“Emily get down here!” Shouted Megan, “we’re not going to a wedding, we’re just fucking.”
Emily looked towards the bathroom door, “one more minute!” She shouted back to her sister. She had to get ready for this. She studied herself. Her F cup tits almost spilled out of the tank top she was in, her equally large ass sat comfortably in the sweatpants she wore, and her dark hair flowed down past her shoulders. She took a deep breath, it was time to fuck her sister. Or rather, it was time for her sister to fuck her. Megan was into bondage, one of her ex’s got her started and she could never stop. But today, Megan would be the one to tie up Emily. Emily stepped out of their bathroom and started down the hallway. She opened the door to the basement and started down the stairs, carefully closing the door behind her. She was greeted by her empty basement. It was finished, with painted walls and carpet, but neither sister really had any use for it. The storage room in the back provided more than enough space for all their stuff, so they only had a couch and a TV down here. But there was also something else in the basement, Megan.
She had already taken the liberty of stripping naked and was sitting on the couch. When she spotted her sister she power walked over to her. Megan reached for her sister's tank top, “take it off, come on,” she said. Emily grabbed her sister's hands. Megan rolled her eyes and smiled, “it’s not like we haven't seen each other naked before,” she pointed out. Megan was right, so Emily lifted her tank top and bra off before moving on to her sweatpants. She slid them off and let them fall to the floor. The two girls embraced, their tits pressing together. Despite being the younger sister, Emily had the bigger tits. Megan’s D’s were impressive, but Emily won the gene lottery in that regard.
Megan broke their hug, “should we start off slow?” She asked her sister. Emily nodded and Megan laughed, “pee it is then,” she declared.
Emily was thrown off, “pee?” She asked.
“Pee,” Megan repeated. She started over to the far side of the basement where the closet was. Megan entered it and pulled out a series of ropes and a small box. “Have you ever done anything with pee before?” Megan asked.
“No,” answered Emily.
Megan looked over at her, “but you want to?” She asked.
Emily recoiled, Megan was right of course but it was still a shock that she knew, “well, yes,” said Emily.
Megan smiled and started untangling the rope, “I’ll tie each other in a sixty nine position,” she held out the box, “here is a timer, after thirty minutes it will open and we’ll be able to cut ourselves loose with the pair of scissors inside.”
Emily nodded along, “what if I don’t have to pee,” she asked.
Megan pointed to the bathroom on the other side of the basement, “in there you’ll find a couple one gallon jugs of water, one for me and one for you, bring them out here and start drinking,” she told her. Emily did as she was told, walking into the bathroom and finding the jugs before bringing them back out. They looked exactly like milk jugs, but filled with water of course. It was a lot of water, maybe a little too much. Megan carefully laid out the ropes on the ground. She picked up one and started tying it to her own ankles, effectively creating cuffs made of rope around them with a length of rope running out of them. She then did the same to her wrists, although she struggled with this. While her sister was struggling, Emily opened up her jug and started sipping. The water went down easy at first, but it quickly became difficult to get down. Megan finished with her ropes before moving on to her sister. She bent over and tied her ankles, before standing up and tying her wrists as well. Both sisters had their wrists free, but with rope around them. Megan then tied a rope around their stomach, before doing the same to her sister. The jug was waiting for her, so she started to drink her own water.
After a few minutes of struggling, the sisters had emptied their jugs and were ready to be bound. Megan led them over to a carpeted part of the floor that she had picked out for them. It had four small U-clamps evenly spaced along the ground. These clamps were small pieces of metal that looked like upside down U’s. “You’ll be on bottom, lay down,” Megan told Emily. Emily first sat on the ground before laying back and facing up towards the ceiling. Megan stepped one leg over her and faced towards her feet. She joined her sister on the floor a few seconds later, her crotch right over her sister's face. She started by tying her own ankle to Emily’s wrist, and then her other ankle to Emily’s other wrist. It took some contorting, but Megan eventually then managed to tie both ankles and wrist to ttwo of the U-clamps. This spread out Emily’s arms above her head and spread Megan’s legs out so that neither girls could move them. Megan moved the box towards one of the clamps in front of her. She leaned forward and took Emily’s legs with her. She first tied their stomachs and chests together. She did the same thing but in reverse, with her own wrists tied to Emily’s ankles. The second tie was tough with only one hand, but she managed to do it. The two sisters were now tied together. Emily laid spread eagle on the ground, unable to move her arms or legs. Megan laid on top of her, but facing towards the ground. The two girls were now inseparable, both of their faces were right on top, or below, the others pussy. It was perfect.
“That went well,” said Megan.
Emily moved a little bit, getting used to her sisters weight on top of her, “what now?” She asked.
“We pee,” said Megan matter of factly.
“But I don’t have to go,” said Emily.
“Well I guess we’ll have to improvise,” said Megan. With that, Megan began slowly licking her sister’s pussy. Emily was not expecting this. Her head shot up in surprise, only for her nose to make contact with Megan’s pussy. Megan jumped in surprise, “a little gentler please,” she joked before going back to her licking. Emily moaned softly to start off. She wanted to return the favor and start eating her sister out, but she held off. Megan’s tongue found every inch of Emily’s pussy. It danced around her clit and moved down to wet her labia with her saliva. Emily was confused by something at first, “how are you so good at this?” She asked between moans.
“I practiced on some of my lesbian friends,” she said, “speaking of practice, you need to start now,’ once she said that she lowered her hips closer to Emily’s head. Emily finally got the hint and raised her mouth to meet her sister's pussy. Megan’s pussy was already pretty wet, so Emily’s tongue glided over her glorious pussy. She started off on her labia, she softly poked the tip of her tongue into her sister’s entrance. Megan moaned into Emily’s pussy, causing more waves of pleasure to flow through her.
Emily continued pushing her tongue inside of her sister. Slowly Megan stopped moaning, “you have to move around a little bit more,” she said. Despite saying this, Megan’s pussy was still dripping wet.
“Ok,” said Emily. She moved her attention back to her pussy lips and flicked them with her tongue. Megan returned to lickingher pussy as well, focusing most of her attention on the clit. Emily’s clit was subjected to her sister's attacks. Her sister had certainly practiced. She was already approaching her first orgasm. But she was able to get out of this though, “I have to pee,” Emily said.
Megan giggled, “go ahead,” she said, “I’ll drink it.”
Emily pushed her head up off the ground, “you’ll drink it?” She asked.
Megan laughed, “why do you think I tied us up like this?”
This threw Emily for a loop, “I don’t know,” she admitted.
“Well trust me, it tastes good, you’ll find out when I have to go,” Megan said. Megan then cupped her mouth around her sister's pussy, ready to take up all the pee into her mouth. It took Emily a little while longer to push her pee out. She, like most people, was used to sitting over a toilet rather than having their own sister ready to drink their piss. With one last firm push the first stream of pee came out of her cunt. It shot straight into Megan’s mouth. He lapped up the warm, sweet nectar of her sister. Taste was never really what drew Megan to piss play, it was intimacy. She had certainly seen her sister pee before, but now the two would drink each other's pee. They would be forever closer after doing this. Emily, who was still rather nervous, pushed her pee out in spurts instead of one long stream, Megan didn’t seem to mind. Eventually Emily felt that she had pushed all her pee out and Megan lapped up the last drops that remained on her pussy lips.
Megan giggled, “my turn,” she said. She moved her hips down closer to Emily’s lips. Emily was nervous, she had never even thought about drinking piss before, but now she didn’t have a choice apparently.
“Do I have to?” Asked Emily.
“Just trust me, it tastes great,” she said. Emily doubted that, but she did trust her sister. Emily trusted her enough to be tied up with her, so she might as well give it a shot. She opened her mouth below Megan’s pussy and raised her head to bring her lips closer. Megan took a few seconds, but the first drops of pee started leaking out of her pussy. They were salt, but also somewhat sweet, it was strange but not unwelcome. The first few drops didn’t compare at all to what Megan had in store. She was a lot more confident than Emily, so when she pushed her pee out it came in one long stream. She could tell Megan was holding back slightly, which she appreciated. She tried her best to lap up and swallow all of her sister's sweet nectar, but some still dripped out and ran down her chin and chest. It was still a strange taste, but for some reason she kept going. Emily kept swallowing her sister’s own pee. The two sisters had seen each other pee before and had seen each other naked before of course, but nothing even close to this had ever been done before. The intimacy and the warmth of the pee made Emily oddly turned on. Her pussy started to get wet again as Megan pushed out the last few drops of her nectar. Emily still wanted more, so she licked up all the spare drops that were deposited on her labia and clit. Megan moaned through these licks, “you’ve learned little sis,” she jokingly said through moans.
Emily didn’t stop. She kept on going, determined to make her sister orgasm, that was the least she could do for Megan after she introduced her to her new piss fetish.
“Make me cum,” moaned Megan, “make me squirt,” she said. Emily did not need a second invitation. She ran her tongue along her sister's slit, she found her labia and her entrance and pushed her tongue inside. Emily carefully avoided her sister's clit, she would use that to send her over the edge. For now, she moved her tongue in and out of Megan’s pussy. This caused her to leak yet more juices, which Emily now happily lapped up. She could feel Megan’s arms and legs moving against her bounds, her hands balled into fists and her toes curled as she almost started her orgasm. Emily withdrew her tongue from her sister and started attacking her clit. This was too much for Megan, who immediately was sent into an orgasm. She cried out in pleasure and instinctively rose her hips up. Emily chased her sister's pussy, she gave her clit a few more licks until she went back down to the floor just in time for Megan to shoot squirt out of her pussy. It wasn’t much, but it was enough to soak Emily’s tits as she lay on the floor. Eventually, Megan lowered her hips back down and Emily licked the last few drops of squirt off her pussy.
“That was hot,” said Megan through labored breaths, “I didn’t know you were that good.”
“I learned from the best,” said Emily. The two laughed.
“I suppose I’ll let your squirt out too,” said Megan.
“But I’m not a squirter,” said Emily.
“You will be after this,” said Megan.
Megan then showed her sister how much she had practiced. Her tongue was strong and it probed around Emily’s pussy. She gasped when Megan found her labia and moaned when she ran her tongue over her clit. Megan was in no mood to build Emily up to an orgasm, she wanted to get her there as quickly as possible. She stuffed her tongue into Emily’s pussy and began to thrust quickly as if she was fucking her with a strap on. Emily assumed that Megan would wait, and slowly build her up to squirting. Clearly though, Megan knew what she was doing. Emily was already almost having an orgasm, but there was a new feeling as well. It was as though she needed to pee, but much different, much more pleasure filled. Megan quickly withdrew and attacked her clit. This sent Emily into her orgasm. She contorted her body with the pleasure, but Megan followed her all the way until she felt the squirt shoot out of her pussy. She screamed out in pleasure as her sister finally let go of her clit. Slowly Emily returned to her normal position as she came down from her orgasm.
“Did I squirt?” Emily asked.
Megan laughed, “you couldn't feel it?” She asked.
Emily smiled, “I just wanted to make sure,” she said.
The two girls giggled together. Over the next few minutes they only made small attempts at pleasuring each other. They would slowly lick and kiss each other's cunts and thighs, making no real attempt to send each other into a second orgasm. Then there was the pee as well. Each sister would drink the others pee and then relieve herself into the other's mouth. It was a continuous cycle. All good things must come to an end however, and eventually the 30 minute timer ran out and the two girls managed to cut themselves out of their bindings.
