Probably Bernie had not fully realised but surely it had lingered at the back of his mind. That Cougar Kendra had manipulated him, and Mom Eliza was the one who had initiated this incestuous relation. Since their first "morning wood" fuck most of their subsequent couplings were the decisions of Eliza . It is an established scientific fact that women with higher than normal male hormone, testosterone, tend to have a higher than normal libido. Eliza most likely was one of them. She must have tried and failed to get more sex with husband, Simon, who had remained constant in his sesxual appetite, the two or three fucks a month guy. Being the good wife that she was she had not commit adultery with another man, other than her son. Her sexual habit also testified to this biological abnormality. She enjoyed fucking at anytime of the day and in any environment.
Bernie's usual trips into town to stock up on groceries and household stuffs were now done together with his mom. This was Eliza's chance to enjoy sex with his son in public or in natural srroundings. She enjoyed the risk and prospect of getting exposed and shocking some unwitting witnesses who might chance upon their fucking.
One such typical day they had had their lunch after their shopping and were relaxing in their car. Eliza started to prepare herself with her vibrator while playing with Bernie's cock. She went to work pulling and pushing his cock through her fist; rolling his balls in her hand and drawing two or three finger nails lightly all the way up the 8" cock again and again. She took just five minutes to get Bernie moaning and hyper-ventilating. When they were both ready she stood behind her car in the parking lot, and leaned on the boot. Eliza just lifted the back of her skirt, and Bernie left his pants on, with only his cock sticking out of the fry. Bernie entered her from behind and started fucking his fully clothed mom. He did not need more stimulation from a naked woman's body even as pedestrian and vehicular traffics moved around them. The extra stimulations for both of them came when some suspicious passersby stared, lingered for those extra seconds, or smiled at them. Less than ten minutes into the fucking Eliza shuddered with her orgasm and Bernie had a great ending while remaining steady on his feet. Then Eliza covered her pussy with two layers of paper towel and squeezed out some of the fluid before walking back to the car.
Even their home-fuckings were inventive and out of the ordinary. It was an hour after dinner, Eliza was leaning on the kitchen table, facing the kitchen door and the big scrren TV in the living room. She was being fucked by Bernie while watching Netflix. As Eliza watched her hero (Tom Hank) making out with his love-interest on the big screen, she was also getting pounded by a big cock, going in and out of her dripping cunt. As usual Bernie was bangging his mom with only the back of her skirt up, and his cock sticking out of the fly of his pants. Suddenly, Daddy Simon who was watching the TV in the living room got up and came into the kitchen to get his beer. The fridge was next to the kitchen door. At this point Bernie stopped the bangging but kept his cock inside his mom. He just switched to massaging mom's shoulders and neck. Dad got his cold beer and went back to his seat, not suspecting a damned thing. They resumed their fucking. Their moanings, and the "putt, putt, putt" sounds made by Bernie's pelvic bangging against mom's butt-cheeks were drowned out by the noise from the TV.
Bernie was obliged to fuck his mom mostly once a week. Bernie had no complaint though. He enjoyed fucking his mom. He also got a bigger weekly allowance and a special meal in town whenever he was on such a date. But he always looked forward to the bonus which was Kendra herself. Bernie's sex goddess could not be anybody else but Kendra. At an interval of four or five weeks Eliza and Bernie would be invited to join Kendra in a threesome sex-capade。 One side effect of all these was Kendra's growing interest and desire to personally experience incest with her son herself. Meanwhile, Kendra had recorded all of their twosome and threesome sex scenes and Bernie somehow had gained access to them. What he did was to send copies of them to Kendra's son, Alex, against whom he had borne a long lasting grudge. He believed Alex had stolen Serena from him, when in fact Serena had never been his to be stolen. By this act he felt he had his ultimate revenge. In his teenager's mind, it went like this: "You fucking stole my girlfriend but I, Bernie, had actually fucked your mom, sucker." As an added twist of his knife he told Alex that it was Kendra's idea to send him those videos.
In the meantime sex-life must go on. One Sunday morning Bernie drove his two lovers in a winnebago/motor home out to the countryside. They had their picnic next to a creek. Giving in to Kendra's request they all went naked and moved into the water. They swam and frolicked in the creek for a while. Then Kendra volunteered to get both mother and son ready for fucking. They were standing in the water as Kendra sucked wetly and noisily on Eliza's nipples and then stooped down to suck her clit. At the same time her hands were busy stroking Bernie's cock and balls. When mother and son declared they were itching for the fucking to start, Kendra directed Eliza to lay down on the unfolded bed next to the winnebago. Bernie got on top of mom and started fucking her missionary style. Kendra's newly acquired fetish got her highly aroused by the mother-son fucking. As Kendra watched the cock plunging into and withdrawing from the cunt she was also massaging her own clit and stroking her own cunt with a dildo. Even though each of them was concentrating on achieving their own pleasure all three of them got their orgasm within minutes of one another.
Upon receiving those videos Alex was just mildly surprised. He felt no animosity towards Bernie either. He knew lots of men and boys desired his mom. He was one of them. But he had not expect Kendra would go for a puny kid like Bernie. When Alex thought about Bernie's statement that it was Kendra's idea to send him those videos, his interpretation could only be that his mom wanted sex with him. He was deeply moved when Kendra hugged him and was closed to tears on seeing him. He squeezed her hard and kissed her on the lips. She had seen little of him since her divorce. They had their supper and settled down in a hotel near the airport. They would make the long journey home tomorrow. After they had their showers, they sat up in bed for a bit of catching up.
"Why out of all the young candidates, you chose Bernie for your first "cougar-fuck", mom?" Alex cheekily questioned mom's sexual judgement. For a few seconds there, Kendra was really caught off guard by that casual remark. But by the time Alex had finished telling her about the videos, she had recovered enough to come back with a retort.
"You think you are a better candidate than Bernie?" She ran her hands through his hair and over his face and then moved in to kissed him on his lips.
Alex was in a much better physical condition than just even a year ago. He was twenty and had bulked-up quite a bit. He slid his hand inside her bath robe and started squeezing and carassing her boobs. Kendra lost no time in taking hold of his erect hard cock and stroking it. After a few minutes they both stood up and took off their robes. Alex saw his mom's hairy pussy for the first time and he touched it with such tenderness. Kendra looked into his eyes and felt the same feelings she had had all those years ago when she was first married to his father. She let go of his cock and started to touch him all over, his chest, his waist, his butt, his neck, his back....She turned over to show him her best asset, her arse. He loved it too and he fondled it, carassed it, squeezed it...
She turned and laid on her back for Alex to enter and fucked her to his first orgasm. Kendra then told him to lie down so that she could keep making love to him until he was hard again. During their second coupling they both had their orgasm. During the next few months mother and son had each other all to themselves.
