"Oh fuck yes, baby girl, then take this my little sluttie daughter. You are a hot little bitch aren't you?" John worked his cock in and out of the young girl's twat. He wrapped his hand into her long blonde hair that perfectly topped her five foot seven inch frame. He thought to himself what a frame it was too. She only weighed about 135 or 140 pounds with 36C boobs and a large 40 inch ass and sexy bedroom blue eyes.
"Yes, daddy I am the hottest fucking God damn bitch in town! Oh Christ daddy I am cumming; come on fucker fill my twat up with your seed." Her father stood about five inches taller than she did and weighed 185 pounds and was very athletically built from working out and running. He felt so good inside of her and could make love to her for hours on end.
"Oh shit, little girl I'm cumming," he exclaimed as he released a massive load of sticky nectar deep in her cunt. At the same time he felt his daughter shudder in her own orgasm as she cried out in pure delight. They collapsed beside each other on his king size bed which hadn't gotten much action since his wife ran off with an English Professor.
His friends told him never to date a Romance Languages Professor but he didn't listen and ended up jilted when she got stars in her eyes when the other guy quoted Shakespeare. As head of the Psychology Department he thought he should be able to handle this break up better than most people but it had been three years and he still thought of his wife from time to time.
His daughter, Susan, had helped him not only by fucking him but she seemed to understand him. After all, he was so very proud of Susan as she had just gotten her Master's degree in Psychology herself. Daddy was so proud of his little girl but now they spent many evenings arguing psychological theory.
Susan had been doing experiments on Pavlov's theories. She thought that she could use conditioned response on adults successfully enough that they might do things in public that they wouldn't normally do. Her father argued that you couldn't make a normally intelligent adult do anything unless you either thoroughly brainwashed them or hypnotized them. He confessed that using behavior modification techniques was very helpful in changing a behavior but these people wanted to change the behavior.
Susan told him she had already had some success with one of her classmates who would put her hand to her ear whenever she heard the word 'hi'. She admitted that behavior would likely wear off unless reinforced with positive feedback. Also, it took her a week and three pounds of M&M's to train her. Her dad's come back was that the girl was only touching her ear because Susan was around and expected it.
"Ok, daddy, I'll bet you that I can cause you to have a conditioned response," she pronounced a little defensively.
"There isn't any way in hell, little girl, I know all of the tricks, you just couldn't do it," John boasted.
"Do you want to bet on it?"
"What is the bet and how long do you get?"
"Ok, daddy I'll have you conditioned in ten days and you will still respond two weeks from today. But, you must do everything I say or the bet is off," Susan said gaining some confidence.
"I will be the model test subject, but will resist the conditioning like any smart adult. So, what are we betting?"
"Ok, if you win I will become your sluttie bitch whore and do anything you want. I'll take it up the ass; find another girl for a threesome, or whatever else you want."
John was excited but had to ask, "And what if you win?"
"Well then daddy your ass is mine. If I want you to put on my panties or fuck in the park you will do it." John didn't like the idea of wearing her panties or fucking in public but agreed knowing that his chances of losing were slim. They sealed their bet with a long passionate kiss lasting a full two minutes.
"Well, Susan what are you going to train me to do?" he asked slightly out of breath. He hoped that it wouldn't be something really embarrassing just in case she should really succeed. His worst fears realized when she told him.
"Well, daddy you will get the biggest tent in your pants whenever prompted. You will get so hard that it will feel as if the skin is two sizes too tight." she responded with a glint in her eyes.
"That is no test, I get hard whenever I see you or hear the word fuck," he snapped back.
"Oh don't worry daddy you will get hard no matter who gives you the cue; man, woman, little c***d, or even shriveled up 110 year old lady. Of course I won't use a word like fuck that wouldn't be fair. But I know I'll make you so fucking hard all of the time for the next two weeks that you will feel like you could cum at any time."
"I will believe that when I see it; the clock is running." Susan stood just smiling at her daddy knowing all of his sexual weaknesses. She was well aware of the power that he had given her as to get a fuck he would practically do anything which would make him putty in her hands for training.
"No, no, no, the clock starts right now because big sexy daddy whenever you hear or say the word 'hi' your big sexy cock will get so hard and big for me. Don't you want to get big and hard for your hot little bitching girl, daddy?"
"Oh yes, baby I love being hard for you and can't wait to get back in that twat of yours."
"Well then, my daddy do what I say, ok? Oh my it looks as if my sexy daddy is hard already." She walked up to him and placed the tip of her finger on his erection through his pants and slowly rubbed up and down on it's length and whispered over and over again the magic word. She must of said 'hi' 100 or more times.
Knowing that it would not be enough just to caress his cock while she said the word she stopped the caressing and walked away. She wanted to reinforce that whenever he heard the word that good things would happen. She didn't think candy or treats would be good enough it would take sex. John had been getting excited by the fondling and protested its sudden end, "Susan, don't leave me hanging you just made me hotter than shit!"
"Do you want to shoot your cum out of that big sexy prick?"
"Oh my fucking God, yes I am so horny."
"Well, I guess I'll help you out this time. Go ahead and pull it out of your pants for me. But, if you want me to make you cum right now you will repeat what I say and say whatever I tell you to say, ok," she cooed seductively standing over him playing with her crotch through her pants. She couldn't believe how turned on she was getting herself; her panties were soaked.
Whipping his cock right out of his trousers he answered eagerly, "Whatever you say just go for it right now; you are driving me crazy already."
Susan had already made her father realize in less than five minutes that he might well lose this bet; therefore she was half way to victory. Sitting back beside him, grasping firmly on his member, she whispered in his ear, "Hi!"
Her father just sat there enjoying her hand wrapped around his cock. Since nothing came out of his mouth Susan let go and backed off a little. It took a moment for him to realize what he was supposed to do and finally half whispered, "Hi."
Yanking hard on his stiff rod she leaned in and licked his ear as she purred, "Hi."
"Hi," he responded without a moment of hesitation this time. Susan let her breast brush against his side as she repeated that word that was sounding sexier and sexier to both of them. As her hand began stroking up and down his member John quickly responded. She repeated herself saying the greeting several more times as he got more and more turned on almost responding before she finished saying the little two letter word.
As she loved giving blow jobs the next part would be easy and fun. Her father's eyes were closed in ecstasy as she asked, "Daddy wants a cock sucking?"
Breathlessly he uttered, "Daddy wants a cock sucking."
"Well then, I want you to say over and over again until you fill my mouth with that sweet jism 'the word hi makes me very hard' and don't stop or pause daddy; I want to hear it loud and clear." Susan snaked herself onto the floor in front of him and smiled up at him. Taking his manhood into her hands she blew across the head softly waiting for him to utter the key phrase.
"The word hi makes me hard. The word hi makes me hard. The word hi makes me hard. The word hi makes me hard. The word hi makes me hard. The word hi makes me hard. The word hi makes me hard. The word hi makes me hard. The word hi makes me hard. The word hi makes me hard. The word hi makes me hard. The word hi makes me hard. The word hi makes me hard. The word hi makes me hard," he spit out rapidly.
Part of Susan couldn't believe that her dad was actually doing what she said but right now more than anything she wanted to swallow his hot sticky seed. She heard a moan come from him and then silence. She knew she was close to getting to drink his cum but had to stop. Pulling her head only a couple of inches away he resumed repeating the phrase. Her head quickly returned to the task of liberating his cum. Up and down him her mouth bobbed back and forth on his long shaft until he filled her gullet with his sweet nectar. She licked her lips in deep satisfaction.
"Wasn't that fun dear daddy?" she asked as she got up and straightened up her clothes. John was still trying to catch his breath from her incredible cock sucking. She looked over him and his semi-hard cock and just smiled broadly. Then pivoting around she practically waltzed away from him.
"Hey, little girl, don't I get to kiss your hot pussy or give you a good hard fucking?" He wasn't sure he could get it back up quickly enough to fuck his daughter but wanted to try. If nothing else he knew that he could make her cum by eating her delicious pussy. A frown came to his face as his daughter just kept strolling away from his shriveling penis.
"Not right now but don't worry my sweet lab rat you will have lots of fun over the next two weeks while I thoroughly condition you and that cock of yours." Susan was proud of herself as not only was she licking the sweet taste of cock honey from her lips but she had her daddy firmly in the palm of her hand. She sat down across the room from daddy and began reading the newspaper. Once she was convinced he had given up for now and was back into watching the television she snuck out of the room.
Going back to her bedroom she quickly discarded her clothing and put on a shortie nightie that didn't even cover her rump. Dousing herself with her sexiest perfume she put her hair up in pig tails. After a few minutes of primping to allow time for her dad's thoughts to wander from sex and get into the sports he was watching she headed back to the living room. Sure enough he had tucked his prick back into his pants and was intensely watching the game. Quietly she snuck up to where he was sitting and pushing her naked crotch into his face purred, "Hi."
"Hi," he instantly answered as the smell of her honey pot totally took over his senses. The smell was too strong and her cunt too close he just couldn't help it as his member grew hard. The vision of her thick blonde pussy literally in his face was just too damn much so he meekly responded, "Hi."
"Are you hard for me?"
"Fuck yes, who wouldn't be with your sexy cunt in their face?" Susan reached down and checked out his lap and sure enough his cock was stiff as a board. Grabbing the TV remote from his hand as she slid her legs further apart she took his head and pushed his face to her cunt lips.
"Oh yes daddy, you are so fucking hard; so, you can eat out my hot little cunt." She had never had her pussy kissed while standing up before but really wanted to try it. She figured this was the perfect opportunity as she could maintain full control of her lusty dad. Using his tongue skillfully he licked all over her lips and the tiny hole before turning his attentions to her hot button of a clit.
"Oh God, daddy, eat it now for me," she whispered hoarsely. Susan found that she had to hold onto John's shoulders tightly or she would fall over. Her legs were bowed far apart as her cunt gyrated in the older man's face. John thought to himself that this was quite a life as he was sitting in his favorite chair eating his favorite sweet dessert. As his daughter came for the first time her honey poured onto her upper legs as he tried to catch every drop.
"You taste so fucking great; but, can I fuck this hot little pussy now?"
"Are you still hard? Let me see?"
"You bet your sexy ass I am!" John almost shouted his response as her dainty fingers checked out the bulge in his pants. Susan pushed herself away from him and pulled the gown off. Getting down on all fours she wiggled her ass at her horny father.
"Well then, strip and plunge that big thing of yours into me." Shedding his clothing he never took his eyes off of her big bouncing ass. In a matter of seconds he was kneeling behind his baby girl and violently shoved his prick deep into her.
Susan was amazed every time her daddy's cock invaded her pussy at how great it really felt. She would never get tired of his talented spear jabbing in and out of her pulsating cunt. He had a wonderful weapon and knew just how to use it. Stroke after stroke the lovers moaned in ecstasy as the girl's hips slammed back at John's prick. The eruption was inevitable as their blood was boiling and breathing was getting ragged. With one last hard push John's seed splashed all over the insides of his daughter's pussy.
Pulling out of the tight quarters of her twat John fell back against his chair and just laid there slumped over trying to recover from the workout. He didn't notice his daughter scurry away to her room. While her father was out of it she made a phone call to her girlfriend, Rhonda, to make arrangements for the next day.
Then she got dressed in her least sexy clothing to give her training its first test. She didn't expect that her dad's cock would really get hard with only a couple of hours of training and certainly not after just coating her cunt with a shitload of his jism It took about half an hour for her to emerge into the living room where once again John had the sports going again. Casually she said, "Hi!"
Looking down at his flacid penis she got excited as it seemed to grow a bit in an effort to get hard. But, alas, he couldn't quite get it up. He meekly responded, "Hi, it is just too worn out after what you did to it."
"I'll forgive you this time," she said merrily as she waltzed off to the kitchen to prepare dinner. Their dinner was routine and a very typical father and daughter time together. They filled the time with everyday small talk. The subject of sex seemed somehow to be taboo while they ate their dinner.
Throughout the rest of the evening Susan continued to play with her father finding reasons to leave the room and re-emerge and say the two letter word that had become very sexy. Without fail his manhood would stretch out his pants. Each time she would give him some type of positive reinforcement whether it was offering up her ass for him to kiss, her boobies to fondle and suck on, or some other form of erotic activity.
As they slept that night she was convinced that her father would get hard each time she greeted him, especially with the sexy reinforcement she had been giving him. But, this was the easy part as he had to get erect whenever anyone said "hi" for her to win the wager. A couple of great tests would come the next day when she went into work for a couple of hours to get ready for the next semester.
She walked into her tiny Teaching Assistant's office and quickly shut the door as she braced herself against the file cabinet she yanked off her panties from under her skirt. She brought the cotton crotch of the red bikini to her nose and knew why her dad loved eating her so much as it smelt so damned good.
Susan could have played with herself right then but had more important things on her mind. Hurriedly she sat down and pulled the phone to the edge of her desk. She placed one leg up on the desk carefully placing her pussy only six inches from the phone. The girl turned on the speaker phone and began dialing her home number. She was briskly rubbing her clit waiting for her dad to answer until she heard him softly answer, "Hello."
"Hi daddy, do you know who this is?"
"Susan, is that you?" he carefully asked.
"Yes daddy, are you hard for me?"
"Well, maybe half hard but not stiff sweetie." Dipping her fingers into her cunt she began playing around with her sopping wet cunt. Once she got herself good and dripping she used her fingers to fuck herself creating a wonderful noise that was clearly audible over the phone line. She edged just a little closer to the microphone of the phone so that the slurping and sucking sound would be even louder for her daddy.
"Daddy, do you hear that, that is my red hot pussy and it is wet just for you. Now, are you hard daddy?" John felt his cock spring to life and become stiffer than he could ever remember. He couldn't believe how sexy the swishing of her cunt sounded.
"Shit, fuck yes, I am so fucking hard." Susan smiled broadly knowing that the next time she talked with him on the phone he would have no trouble getting a hard on. She would have to cut the conversation short as she didn't want him to risk using up his precious seed on a phone call.
She told him to chant out loud 50 times that the magic word would make him hard and he would be handsomely rewarded. Repeating the short phrase over and over again daddy was a bit frustrated when he hung up from Susan and considered whacking off but just then there was a knock at the door.
Opening the door the sight that greeted the older man really got his heart pounding. There was the five and a half foot tall Rhonda with her blonde hair blowing in the wind and her pert 36C tits virtually staring at him as they were standing straight up in her thin blouse. The thin girl's deep blue eyes twinkled at him as she purred, "Hi."
John's Cock instantly regained the stiffness that it had lost when the knock came on the door. Rhonda was a true vision of sexuality. She had no trouble noticing the sexy older man's erection as the tent in his pants was absolutely huge. The report to Susan would be a positive one and she could give John some positive reinforcement. So, tugging at her ear, she replied, "Hi, Mr. Anderson may I come in?"
"By all means, my dear; what can I do for you today?" He panted. The girl ran into the room grazing John with the hip of her tight shorts as she slammed the door as she went past the astonished man. Looking him straight in the eyes she began unfastening her blouse.
"Susan told me about her bet with you and I agreed to help her. And, either you are very happy to see me or she is winning the bet as I can see that sexy big thing in your trousers. Now I get to reward you for getting hard like Susan ordered you to." She dropped the blouse from her shoulders exposing her perfect boobs that didn't need a bra to hold them up.
Quite literally she collapsed to the floor in front of him and opened his pants and pulled them and his boxers down to his knees. Rolling his balls between her fingers she used the muscles of her cheeks to suck his prick deep into her throat. John let out a loud moan that sounded like he was in great pain but nothing could have been further from the truth, as all he could say was, "Fuck, shit, shit, my fucking God."
It had been too long since Rhonda had enjoyed a big hunk of cock meat. Being bisexual lately she had found many more worthwhile cunts to eat up than quality cocks. But, no problem here this man's cock filled her entire mouth to its limit and tasted absolutely divine. Wrapping his fingers into her hair John was soon mouth fucking the hot slut.
She obviously loved it as her sucking became harder as her tongue licked at any part of his member that it could reach. Squeezing his balls harder she moaned in enjoyment from around the huge poker in her mouth. As she jabbed a finger into his asshole playing with his prostate he rewarded her with a delightful tasty load of his spunk that she hurriedly swallowed in an effort not to lose any of the sticky stuff.
Letting go of his still hard prick and licking her lips Rhonda stood back up. Gazing into his eyes she gave his member a squeeze with her hand telling him, "You know what, Susan told me we could fuck but only if you said 'Saying hi makes me Hard' fifty times while I undress us."
As Rhonda reached for the top button of John's shirt he rapidly spit out the words that would allow him into the girl's pussy. He talked so fast that they were both convinced that he accomplished the assignment before Rhonda wiggled out of her tight fitting shorts revealing a sexy pair of pink bikini panties, causing John to exclaim, "My God those are so fucking sexy!"
"You can take them off for me and then get that cock in my pussy. I want you to fuck me doggie style right now," she cooed smiling seductively. He ran his hands over the silky surface as he loved the feeling of tight fitting panties against a woman's body. Then with one hard tug he yanked them off of her ass and down her legs. Collapsing to the floor Rhonda rolled onto all fours as John aimed his prick for the Promised Land.
His cock slipped smoothly into her slippery depths. Rarely had she felt the walls of her twat stretched so much by a man's cock; it felt fantastic. Her back was arched almost into a u-shape as she pushed against the invading rod while she panted heavily. Stroke after hard stroke he rammed his manhood into her cunt.
John thought that this chick might be young but she really knew how to use her pussy muscles on his cock. As great as she was fucking him he knew that he wouldn't last long. The fuckers were moaning in ecstasy as John unloaded himself then fell onto the carpet beside her. Rhonda wasn't done cumming so she quickly jumped onto his face and ground herself in his mouth having one massive orgasm after another as John greedily devoured all of the juices.
Having satisfied herself Rhonda got up and threw back on her clothing and headed out the door. On her way out she reassured the older man that she would return sometime in the future. Worn out, John didn't move a muscle and took a nap right where she had left him. Meanwhile Rhonda skipped to her car and drove it straight to campus to report to Susan on the success of her meeting.
It would be an understatement to say that Susan was thrilled at what Rhonda told her. But, she knew that she had a long ways to go before she claimed total victory. First, was to see if dad would get hard with more than one girl saying that word to him. Then, would he get erect if another man spoke to him. She figured she had about 24 hours to accomplish this before weaning him from the rewards of super sex.
It had worked so well with Rhonda that three weeks after starting the project Rhonda still pulled at her ear every time she was greeted. Rhonda quickly agreed to go back over to their house that evening with Susan. Rhonda exclaimed, "Your daddy is one of the best lays I have ever had in my fucking life! I'd fuck him anytime!"
After about an hour long nap John got up, got dressed, got a drink, and began looking over some articles to see if any would be good to use for class next semester. Several hours passed when he heard the front door open. He looked up to see Rhonda and Susan entering and without even thinking he blurted out, "Hi, ladies."
"Hi, Professor Greene," Rhonda said in a hoarse sultry whisper.
"Hi, daddy," Susan joined in her best schoolgirl sensual tone. John didn't have to look at his lap or touch his crotch as he could feel his prick grow stiff as a board in two seconds flat. One quick glance and the ladies knew it too as it looked like his cock would tear a hole in his shorts.
"What are you girls up to," he bravely asked trying to ignore his obvious hard on. He knew he had been caught as both girls walked closer and closer to him. In unison they removed their shirts and stopped about three feet away from him.
"Well, daddy, we came to see if the word 'hi' still makes you hard. It appears to me that you are very hard so Rhonda and I will give you some positive reinforcement," cooed his daughter. The girls faced each other and wrapping their arms around each other kissed passionately. In just a few moments they were removing the remainder of each other's clothing. John couldn't believe the sight before him as soon his daughter was rolling around on the floor in front of him in a sixty nine with another woman.
"Thank you Professor, if Susan hadn't found those pictures of you doing it with some other guy she would never have had the courage to try sex with a woman; god damn it she is so fucking good at it, too," Rhonda nearly screamed as she momentarily pulled her face from Susan's musty depths. John was puzzled for a moment and then realized that Susan must have found the pictures of him with Fred Perkins his next door neighbor who he had sex with on a dare and they had taken pictures of it to prove to their wife's.
Shrugging his shoulders he figured there was nothing he could do about Susan knowing about it now but sit there and enjoy and hope for audience participation. The smell of cunt juice was driving him nuts as he watched and heard the sound of their tongues lapping up the sweet pussy nectar. Finally, Susan who was closer sat straight up covering Rhonda's face completely with her hips and reached over and unfastened his fly.
"Well, daddy, don't just sit there; get up off of your ass, stand up and get your cock in my horny little mouth." Susan demanded. Eager to comply the professor was up in a flash and out of his clothing and placing one foot on each side of Rhonda's body quickly began mouth fucking his lovely daughter.
To Susan this was incredible having her father's prick invading her mouth while her classmate was tonguing furiously all over her cunny. Just then Rhonda pushed lightly but firmly on her girlfriend's ass causing Susan to lift off of her wet face. She complained loudly, "How about my fucking pussy?"
Not wanting to leave Rhonda feeling left out Susan pushed on John's hips and laid down beside her friend and patted the floor indicating where her father was to join them. The trio quickly formed a triangle with John eating out Rhonda while Susan was being eaten by Rhonda as Susan continued sucking off her father. Hands caressed whatever skin they could find; squeezing and rubbing tits an asses. Moans of wild ecstasy came from all of them. Over the next two hours they tried every position they could think of.
John's favorite moment of the night came when he was fucking his daughter on the coffee table with her legs dangling from the side. Rhonda was sitting on her face having her asshole eaten out while she frigged her clit. John leaned in and received the most passionate tongue kissing he could ever remember while squeezing the fucking crap out of both ladies big boobs. Coming up for air for a moment Rhonda commented, "Oh fuck I love being a fucking whore slut."
When Rhonda climbed off and got her clothes back on to leave she could barely walk but told them she had to get home and do something's herself to get ready for school. John and his daughter just slept that night right there on the living room floor. John awoke in the morning to find that she had already left.
Puttering around the house John was enjoying the down time as this experiment with his daughter was beginning to wear him out. Even as he thought about being worn out he had to smile to himself as it was also the most fun he had in a long time. At about noon the door bell rang; John had no idea who it could be.
Looking through the small window in the front door he saw Fred Perkins standing there in a tight fitting t-shirt and shorts. Fred was very athletic and had muscles rippling out of every part of his 6'3" 215 pound body. He was surprised that Susan and Rhonda hadn't been fucking Fred instead of him. As John opened the door Fred greeted him, "Hi, John, how the fuck are you doing good buddy?"
"Hi Fred, I am doing fine; how about you?" To his surprise he could feel the erection grow in his own shorts and just hoped his friend wouldn't notice; but he had no such luck. "I'm fine too; it appears that your prick is really happy to see me." Fred walked a couple of steps closer to his friend. John was nervous and wasn't sure what to do. Fred just smiled broadly at John making John that much more nervous.
"It is this dumb experiment Susan is doing on me telling me that I will get hard every time someone says 'hi'," John sputtered out. Now Fred took another step so that they were face to face.
"Oh kind of like the 1904 Pavlov experiments with the dog and bell with the meat paste; I'd say Susan is succeeding as you are as hard as a board and I am turned on beyond belief. Now let me see that wonderful thing." John stood frozen like a statue as Fred gently stroked up and down the length of his rod before wrapping his fingers around it. A groan escaped John as Fred placed his arms around his back and gently gave him a soft kiss right on his lips.
Susan's father couldn't help himself as he quickly embraced Fred caressing the younger man's back. They kissed again; this time it was a hungry passionate kiss. Their bodies were grinding hard against each other as they tried to devour one another with their mouths. Simultaneously they pushed each other's shorts and underwear off of their asses and down their legs. As they stepped out of them they lifted the shirts off over their heads pausing for only a second in their passionate kiss.
"Oh fuck, Fred, make love to me," John panted. They loved the feel of their cocks rubbing up against each other and continued to grind them together. Both cocks were so hard that at times it was almost like a sword fight down there; it was a true cock fight. Fred held John tighter and began nibbling on his ear working his way to his older neighbor's neck.
He sucked and nibbled on the spot were the neck meets the shoulder until John thought he would go nuts as it felt so fucking good. Fred's hands worked their way down John's back until they found his ass at the same time he began suckling on Johns pert little nipples. It all felt so wonderful to John but not half as good as when Fred got to his cock. Tenderly and lovingly Fred kissed and licked all over the erect penis. Making love to it with his tongue, sliding it up and down the length of the erection, before taking it deep inside his mouth and giving John a blow job he would not soon forget.
While he mouth fucked John Fred began to play in Ernst fondling his partner's ass cheeks. He caressed all over John's rear end before working his fingers down the crack of the ass and finally to his puckering little rosebud. As he poked his finger inside of John his sucking became more furious. John had been caressing the top of his lover's head but now was holding onto it for dear life.
The eruption exploded deep into Fred's throat as he gulped and swallowed every bit he could muster. Then patting John's ass he again let go of the still rigid pole and stood up behind John. Sweetly he planted tender kisses on the back of John's neck and shoulders. His cock was resting in the crack of John's butt.
Slowly Fred slithered his cock up and down between his friend's ass cheeks as he pinched and teased his lover's nipples. He worked his kisses down John's back until he was resting on his knees. His cock had fallen and was resting on his partner's calves. He didn't care as now he had found John's ass with his lips.
Feverishly he worked over the skinny ass with his mouth as he grabbed and kneaded the cheeks; until he was pulling them apart with each caress. As if licking an ice cream cone Fred licked the crevice from bottom to top over and over again. Finding John's stink hole Fred stuck his tongue in as far as it would go; poking in and out. Then, giving a push on the back of John's knee he signaled for his neighbor to fall to the floor.
Excitedly, John got down on all fours pushing his ass up in the air as far as he could get it. Fred resumed kissing the tiny shithole but this time his kisses were much wetter as he was trying to provide some natural lubrication. Happy with the job he had done in wetting John's backdoor Fred aimed his cock for the handsome anus in front of him and pushed in. He used a long steady pressure, not too hard or fast but not too slow either.
"Oh fuck, I'd forgotten how good this feels. Oh yes, John fuck my ass hard." Fred was smart enough to know that John really didn't want it hard, at least, not yet. After letting John's asshole get used to its invader Fred picked up his pace and reached around and began flogging his buddy's cock. Gradually, Fred's strokes got harder and harder and faster and faster, until his prick was a blur going in and out of the tight rectum.
Pounding and pounding as hard as he could Fred knew he would make a large deposit in this wonderful shit tunnel very soon. John was breathless as he continued his thrusting. Then he felt his nut sack tighten and out poured his jism coating the insides of John's poop shoot just as John sprayed a load of his own hot seed onto the floor.
"The word 'hi' does make you hard doesn't it?" Fred asked as he fell to the floor. He scooted up on the carpet and gave John a passionate kiss.
"How did you know about that?" John retorted as he returned the favor by giving Fred another kiss.
"Remember, you told me when I came in besides that sweet slut Rhonda told me about it late last night while she was sitting on my face after leaving here. She promised to fuck me again if I helped Susan and even give me a pair of her cum soaked panties. God John, I'd almost forgotten how great it was with you. Now how about cleaning off my cock?" John moved into position and took Fred's cock in hand.
"Shit yes, Fred, this fucking cock of yours is fantastic! Come back tomorrow and it will be my turn to ram my fucking cock up your ass hole, you mother fucking son of a bitch." Eagerly John licked and sucked all of the combined juices off Fred's half hard pole until not a trace of anything remained on it.
Tuckered out Fred lumbered to his feet and quickly got his stuff together and left. John couldn't help but wonder what was next. He was somewhat disappointed that evening when all he got was his daughter to fuck him over and over again. It was fun and exciting but not something new. Still, in all, she was the best fuck he had ever had.
Over the next few days Susan gradually cut back on the reward while carefully monitoring her father's reaction whenever she greeted him. It appeared to be working as whenever she, Rhonda, or Fred said 'hi' to him the woody in his trousers was clearly visible. By the seventh day she was ready for the ultimate test.
They went out to the local mall and greeted everyone they met. Most of the time she could tell that he was erect but after awhile he didn't seem as stiff. She decided that they would have to go out again the next day, this time to the park. The first couple of times they greeted people John couldn't resist getting hard.
The first person they came across was a voluptuous girl in a bikini and then a cute couple making out. But, when a grandmother smiled broadly and greeted them John's cock barely budged until Susan whispered in his ear, "daddy the word 'hi' makes you hard and my cunt all tingly and dripping wet."
When the older lady was out of sight Susan threw her arms around her daddy's neck kissing him passionately and giving the bulge now forming in his pants a hard squeeze. After about another hour of walking Susan was convinced that she had him trained as she only had to stop twice more out of about fifty people they greeted. He wasn't about to tell Susan but John knew that she had won and decided it was pointless to fight it; maybe he would enjoy wearing her panties.
After ten days their rule was that Susan had to quit rewarding John for getting hard on cue. That didn't mean that they didn't have wild sex every night then four days later the big test came as they would spend two hours walking various places to see if Susan's training had worked on her father.
John had insisted that Susan couldn't mention anything about the bet or anything related to sex as they walked around as this might cause him to get hard for reasons other than the experiment. The two exchanged some small talk but there didn't seem to be a lot to say as their time over the last two weeks had been consumed by the experiment and sex.
First they returned to the mall and Susan had no problem telling that her father got hard every time someone greeted them. It didn't matter what they looked like or how old or young they were. But, Susan knew that this wasn't a true test as it was easy to get her dad hard in this crowded environment and he would pretty much stay rigid.
Next they walked around the neighborhood and the nearby school and again her daddy got stiff right on cue. Their final stop was the park. The girl knew that this was the real test as if anything could take her dad's mind off of sex it was the beauty of nature. She reasoned that if he was still getting stiff after greeting anyone he saw it must truly be a conditioned response. Person after person greeted John and Susan and each and every time his pole rose to attention just as Susan had trained it to do.
Giggling to himself, John thought his cock was almost like an elevator going up and down. With the two hour test coming to an end the couple found a quiet corner of the park with a seldom used picnic bench. As John settled onto the bench his daughter sat in front of him on the table putting her feet on the bench to his sides while placing her arms on his shoulders and asked, "Well, daddy did my little experiment work? Are you conditioned to respond how I trained you?"
She knew that her father was a very honest man and that she did not have to worry about him feeding her some story; dejectedly he would admit it. Knowing the consequences of his answer, but also knowing that now they could have sex again whenever they wanted too, John confessed, "Well god damn it, I guess you did it little girl. I wouldn't have believed it unless I was living it. You got me, you won the bet, you totally conditioned my pecker; congratulations."
A victory smile came to her face. It felt so good to finally get one over on her daddy. He was so smart that she rarely had been able to keep up with his intellect. She didn't care that she used his own penis against him. Confident and proud she kicked off her sandals and drew her bare feet to the bulge in his pants and toying with it cooed, "I told you I could do it. It looks as if your cock is still hard, but now it is time to pay up."
"Right now?" he asked with a tremble in his voice as he had never been much of an exhibitionist. His daughter pulled her dress up over her waist revealing a bright purple pair of bikini panties as she spread her legs apart.
"Oh yes, sweet daddy, take off your little girl's panties and eat my pussy right here in the park just like you agreed to." A man of his word John reached up to his daughter's waist and hooking his fingers in the sides of the undies yanked them all of the way off.
Dr****g her legs over the older man's shoulders Susan leaned back and opened her hot steamy twat for him. As much as he was worried about some one seeing them this was just too fucking good to pass up. As she felt the first hot lick of his tongue she pulled her dress off over her head and tore off her bra; now sitting in the park totally nude.
John nipped and sucked on her little button clit as Susan began tugging and twisting on her nipples. As he eagerly sucked up her magical juices he got quite a surprise when she began moaning out loud right there in the park. The real shock came when she yelled out, "Oh yes, eat me; oh fuck that feels so damn good; oh yes lap it up!"
Lifting his face away he urged her, "hush, Susan, someone will here you."
"I don't care if they do; I don't care if they watch; just eat my cunt; it feels so great." As worried as John was about being caught or even arrested if a cop saw them with his daughter stretched out naked the scent and taste of Susan's pussy was just too powerful. Voraciously John dove right back in to her hairy twat. Susan's juices gushed all over his face as she came over and over again.
"I think this is the most sweet honey you have ever given me, my fucking God!" He was struggling to lick up every drop that the girl provided him. As her body shuddered for at least the fifth time she pushed away from him and picked up her dress. John thought their fun in the park was over, but then Susan laid her dress out across the table like it was a sheet.
"Strip, and bury that pecker of yours in my cunt; I need it now," she implored as she smoothed out the dress. As John took off his shirt his daughter took it from him and rolled it up and carefully placed it on the dress to act as a pillow. Little did John know that Rhonda and Fred were watching the whole thing from a cluster of bushes only about twenty feet away.
"Oh my fucking God she did it, Susan won the bet," Rhonda exclaimed Fred was standing mostly behind her nibbling on her neck as he cupped her tits playing gently with the beautiful orbs. Realizing that the real fun was about to begin Rhonda reached over and unzipped Fred's fly and deftly reached in and pulled out his cock and began softly stroking his stiff member.
"Fuck me, now; I cannot wait any longer," exhorted Fred.
"Just watch for Susan's signal and we'll have plenty of fun. But, since Susan won the bet you can go ahead and have my panties as soon as you take them off of me." His hands were under Rhonda's dress feeling all over the underwear, loving the silky texture. He had no problem sliding them off of her rump or down those sexy legs as Rhonda was only too eager to cooperate.
Rhonda kept her dress lifted for Fred as he fell to his knees behind her to take the underwear the rest of the way off from her feet. She first lifted one foot and than the other for him as he slipped them off careful not to let the sexy garment touch the ground. He brought them to his nose and took a deep breath of her heavenly aroma before stuffing them in his pocket. It was then that he realized that her sexy ass was directly in front of him.
Instantly, his mouth found her deep crack and he began licking up and down its length. Rhonda let the dress fall over his head as she ground her ass into his mouth. Rhonda was blown away by the situation as here was a dirty old man eating out her stinky butt as she watched John pound away on Susan's cunt. Susan saw John's eyes close in intense pleasure and knew it was time for their added fun.
She waved over at the bushes where Rhonda had told her they would be. Rhonda was so into watching John's massive cock go in and out of that hot twat that at first she didn't see her girlfriend's signal. Susan waved again and this time Rhonda saw it and as she shoved Fred's head out of her ass and excitedly proclaimed, "Oh fuck, Fred, it is time let's strip and get over there!"
For Rhonda stripping was easy as she pulled the dress off over her head and yanked off her bra. Then she watched impatiently as Fred fumbled with his clothing. Finally, they were both nervously standing there in the buff as Rhonda handed him her clothes and instructed him to place all of it on the bench of the picnic table. Susan caught a glimpse of their approach out of the corner of her eye and lovingly licked her lips.
Sneaking up on John Rhonda jabbed a finger into his asshole causing him to jump almost falling out of Susan's twat. But, Rhonda pushed her hand against his cheeks as she swung around in front of him and stuck her tongue halfway down his throat as he realized who she was. For Susan there was no surprise as Fred headed straight for her. She grabbed his pecker and sliding her head to the edge of the table sucked his big member into her ravenis mouth. Rhonda Yanked John's hand off of Susan's tits and put it on her own boobs.
With one hand she drew John's mouth to her heaving chest and replaced John's hand on Susan's boobs with her own. As Rhonda's other hand returned to his butt and she pushed a finger up to his prostate John noticed that Fred had joined them and groaned, "We all could get in so much fucking trouble."
"But, what a great way to go," countered Fred as he was fucking Susan's mouth savagely with his fingers intertwined in her hair. Susan used one hand to fondle Fred's cock and balls as his manhood pummeled her mouth and she used the other to caress Rhonda's ass. John and Susan were somehow able to maintain their rhythm as they continued their hard fucking with their moans and groans getting louder and louder. Then, Susan came with a shriek as John dumped a load of hot spunk into her hot tunnel.
Moving quickly to the grass Rhonda shook her ass at her friends. The three others followed her. Fred didn't wait for an invitation and shoved his cock deep into her blistering hot cunt as Susan took a position sitting on her girl friend's face. For a moment John was lost for something to do. As he watched Fred pound Rhonda he was getting hard again looking at Fred's little ass.
He climbed in behind his buddy and rammed a finger up his shithole and then two fingers. Deciding Fred's rear passage was ready John stopped Fred's fucking just long enough to ram his prick into Fred's shit tunnel. It took a few strokes but Fred and John got their timing perfect so that John and Fred's cocks both got perfect friction.
In no time John exploded into Fred's ass as Fred did the same to Rhonda as Susan drenched Rhonda's face with cunt juices. The foursome was totally oblivious to their surroundings as they switched positions and continued their outdoor fun for another hour. Everyone had a chance doing whatever struck their fancy. Few words had to be spoken as everyone seemed to move from one person to another in perfect harmony.
Once it was clear that they were all wore out they all stood up and exchanged one last round of kisses. As Susan shook out her dress she purred, "That was great and it is only the beginning, sweet daddy. You will have a lot more great adventures like this one."
As Susan pulled the wrinkled dress down over her head a thunderous round of applause broke out. There were about 25 people gathered around their rendezvous point having heard the noise they had come to see what was going on only to find the foursome in carnal pleasures. Red faced they hurriedly threw their clothes on their bodies.
"At least there wasn't a cop around," sighed John. Fred had frowned when Rhonda made him carry the clothes from the bushes but was glad now that she did.
"And who do you think I am," a voice rang out from the assembly. It was one of the city's finest firmly gripping his night stick looking menacingly at them. Silence fell over the crowd as they wondered what would be the next act in this show. The foursome looked at each other trying to decide how to get out of this sticky wicket.
"Officer, we are sorry, I don't know what got into us; we just couldn't seem to help ourselves," Susan answered using her cutest little girl voice.
"I ought to run the four of you in for lude behavior, disturbing the peace, and indecent exposure. But, I have been impotent for four months and after watching your sexy little performance out here my cock is harder than it has been in 15 years. So, I will let you go this one time since because of you I will be able to make my wife happy tonight. Just don't do it again," the police officer said now smiling.
"Thank you sir," Rhonda cooed as she walked over to him and gave him a passionate kiss on the lips. She reached for his groin and gave his prick a squeeze. Figuring that returning the kiss would make him even hornier for his wife tonight he kissed her back passionately as he felt up her boobs and ass.
"You sure should make your wife happy with this nice weapon," Susan whispered as she gave his big tool a very hard squeeze as she too kissed him. The cop thought about fucking one of the girls but decided he had better wait for his wife as she had first dibs on his pecker. Maybe if he found them out here again he would fuck the sluts but right now he settled for feeling up Susan's ass and boobs and running his fingers through her pubic hair as she hadn't bothered putting back on her panties in the shock of the moment.
Breaking the embrace Susan turned and began to walk away with her fuck mates to another wild round of applause from the assembly. As they walked Fred made sure Rhonda's panties were still safely in his pocket. All of them felt extreme relief that the cop had not arrested them and were soon laughing and giggling together. Fred escorted Rhonda home and into her bed; leaving father and daughter alone again.
"Daddy, I knew I would win and see it was fun to fuck in the park," Susan purred as she settled onto her father's lap
"But, baby girl, we damn near got arrested doing that."
"That is what made it fun! And see, dad, because I won the experiment I get to have you as my fuck toy to do whatever I want. And for the rest of the night I want you to worship my ass. You must be giving it attention at all times with your hands, feet, mouth, or pecker until I leave for work in the morning." As she said this she took back off the dress leaving herself in nothing but her bra. She stood up in front of him, her ass in his face.
"Oh my god, your ass is fucking unbelievable; so fucking sexy."
"Then kiss it; come on daddy eat my shit hole. That's right, fuck yes, lick it up; deeper daddy," she moaned as John tongued at her back door. Once he tried to reach around front and Susan slapped his hands away making it clear that all she wanted was a good nasty ass loving. They spent the night with John pawing and tonguing with her ass.
They slept with his cock buried between her ass cheeks. They had started to go to sleep with his head on her ass but it was too hot under the covers for John. Susan woke him with a sensual kiss the next morning. He started to get up to piss but she stopped him and handed him a pair of her dirty panties.
"Put these panties on for me, after all, a bet is a bet," she smirked. Shrugging his shoulders, in resignation, John complied and darned the garment eliciting wolf whistles from his still nude daughter.
They went off to work that day with John's balls constricted in the sexy panties. Needless to say, not a minute went by that he didn't think about his little girl. They were in each other's arms in a flash when they got home that night. Although Susan enjoyed the company of Fred and Rhonda something about these times with her daddy were extra special. They never seemed to tire of one another and always looked for new things to try. It didn't take long for the bet to be forgotten as they returned to their everyday life. Their sex life only seemed to grow more and more intense.
As for Rhonda and Fred they were having similar good times and still enjoyed getting together with John and Susan about once a week. A couple of weeks later the next semester started at school and both John and Susan resumed their teaching. Susan presented a paper on conditioned response changing John's response from his cock getting hard to tugging on his ear like Rhonda and got rave reviews on it.
John found himself having to change his entire section on conditioned response in his lecture as a result of what his daughter had done to him. He somehow didn't mind though as this price had been well worth the pleasure. It has now been over six months since Susan challenged her father and she can't help but notice whenever they go out her dad's cock still springs to life whenever someone says the magic word.
Even the other day when they came across a 93 year old lady his cock nearly bulged out of his pants when she innocently said, "hi."
