"Ta-da! Behold the new full-size bed," said Jessica as she let her brother into her apartment.
"Very nice," Joey replied. "Now all you need is a full-size apartment to keep it in." The bed took up a lot of the one big room.
"Maybe when I get a raise. But check this out," she said, holding up a corner of the large blanket that covered the bed. "Absorbent on top, waterproof underneath."
"Cool. Somebody actually makes these just for pee play?"
"They're marketed mostly for pets and little kids, but they have other uses. Sit down and I'll get us some water."
Joey sat at the small table and watched his sister walk over to the kitchen alcove. As usual, she wore a big, loose sweater that tended to hide her full, round tits. But her jeans showed off the curves of her ass quite plainly. She came back to the table and sat across from him.
"So give me your report on the dating app," said Jessica. "How many responses did you get?"
"Zero."
"None? No messages at all?"
"I told you," said Joey. "Even in the raunchiest forum, no woman is going to respond to a profile that says the guy is into pee sex. Not to mention the part about being non-monogamous, and that's before even getting into all my more general disadvantages. The only positive thing was that I blurred my face in the profile picture."
"Now, stop that. You're a perfectly desirable guy. We knew the peeing thing would mean you might not get any responses, but we had to try it just to be sure."
"For science," said Joey with a grin.
She laughed. "Yeah, for science. The next step is to try again with a proper photo and without saying anything about peeing."
"Yeah. That's where it will get really discouraging. I'm not in a hurry." He took a swig of water and asked, "How did you make out? I bet you got hundreds of responses, right?"
"Well, to be honest," Jessica said guiltily, "I haven't actually made my profile visible yet."
"What? But this whole thing was your idea!"
"I know, I know. But I'm... I'm thinking about kind of a radical change in strategy."
"Like what? You mean leave the peeing out of your profile?"
"No. I mean leave the peeing in but say I'm looking for a woman." She watched him to see his reaction.
"Whoa. I know you've had some bad experiences with men, but that does seem kind of drastic," said Joey in a half-joking tone.
"No, I'm serious." She paused, thinking about how to explain. "You know, I never would have expected everything that's happened between us. It's made me question all my other assumptions about sex."
"Wow. Okay," said Joey more seriously. "But you've never told me before that you're interested in women that way."
"Oh, I've thought about it," said Jessica. "As a fantasy. But I'm attracted to men at least as much, and at first I guess I felt like it was easier just to stick with that. But now, when I try to picture myself having sex with some guy, well, I keep thinking that it couldn't feel as good as it does with you."
"Aw, Jess."
"But when I imagine it with a woman, it's different. And now that we're trying to work out how to see other people and still keep having fun with each other, why shouldn't I explore that option? It doesn't upset you, does it?"
Joey reached across the table and squeezed her hand. "Of course not, Jess. If it makes you happy, I think it's great."
She smiled at him affectionately. After a moment, her smile turned mischievous and she said, "Thinking about me having sex with another woman is making you hard, isn't?"
"As a rock. And boy, do I have to pee."
"Me too. Meeting adjourned. It's time to break in the new bed."
They quickly stripped off their clothes. Joey watched his sister's tits bounce enticingly as she clambered onto the bed. "I want a good long drink," said Jessica.
Joey got up on his knees in the middle of the bed and Jessica knelt in front of him, bending down to take his dick into her mouth and suck on it. Then she held it in front of her open mouth, stuck out her tongue, and looked up at him expectantly.
Joey relaxed and the pee almost immediately dribbled from his hard dick onto her tongue, then shot in a stream into her mouth. Jessica lunged forward and clamped her lips around the head of his pissing dick. She swallowed quickly while his hot pee continued gushing into her mouth. When she couldn't handle any more, she swirled her tongue around the head of Joey's dick, making him stop peeing with a couple of final spurts.
"Oh fuck, that felt good," Joey sighed.
Jessica released him from her mouth, licked her lips, and smiled up at him. "It's crazy how much I've come to love the way pee tastes," she said. "It tastes like sex."
"Yeah, I can't wait to taste yours."
"Give me a little more first," said Jessica, and stuck out her tongue again. Once he started peeing again, she quickly stuffed his dick into her mouth and started licking and sucking on it, making her brother experience another pee ejaculation.
Joey moaned and sat down on the bed.
"Your turn," said Jessica. "Lie down." He settled onto his back and she turned around to get on top of him in the 69 position. Joey spread her pussy lips with his fingers, licked all over her pussy, and flicked at her clit with his tongue. He moved his hands to her ass cheeks and she pushed her pussy further down over his mouth. That was his cue to stop licking.
Joey waited, his open mouth against his sister's pussy, while she relaxed and let her pee flow. The warm, slightly tangy liquid filled his mouth slowly at first, then in a stronger stream. He swallowed, then stuck out his tongue and lapped at her clit. "Ooh, fuck," Jessica moaned, as her pee slowed to stop. "Lick me some more and then let's do that again."
Joey felt her sucking and licking his dick while he went to work on her clit with his tongue. "Ooh, stop, I'm getting close," she said, then held his dick in her mouth like a pacifier. Her pee started again. He waited until it was coming strong, then resumed licking her clit. She made muffled noises around his dick as her orgasm hit her. Her pee stopped, then spurted a few times over his tongue. She groaned and relaxed on top of him while he ran his tongue all over her pee-soaked pussy.
Jessica rolled off of her brother and sat up on the bed, grinning down at him. "I love that so much," she said happily.
Joey was still lying on his back, stroking his dick as he admired his sister's curvy, nude body. "What do you want to do next?" he asked.
"I need to pee a little more, then let's fuck."
"Pee on my dick, okay?"
Jessica knelt over her brother's dick, spread her pussy lips with her fingers, and played a stream of pee over his cock and balls. After a moment Joey started peeing too, aiming his dick to splash the pee over her tits and face.
"Ooh!" Jessica giggled and suddenly jumped on top of him, mashing her pussy against his dick and her mouth against his lips. She stuck her tongue in his mouth while reaching down between their bodies with one hand and guiding his dick into her wet pussy. They humped against each other, bringing his dick back to full hardness.
"You got any pee left?" she murmured into his ear.
