We were both adults, way past the point where anyone could call it anything but pure filthy need. I was twenty-eight, she was twenty-six, and the house was ours for the weekend while the parents were gone. It started with beers on the couch, the kind of talk that got dirtier the more we drank. She’d always been the bold one. “You ever piss on a girl?” she asked, smirking over the rim of her bottle. I laughed it off at first, but the way her eyes locked on mine said she wasn’t joking.
By the third round she was straddling my lap, grinding slow, her shorts already damp from more than just sweat. “I want it,” she whispered. “All of it. Your piss, your cum, everything. Right here, right now.” My cock was rock hard against her before she even finished the sentence. We didn’t bother with the bedroom. The bathroom was closer, and the shower stall felt right for what we both knew was coming.
She stripped fast, dropping her clothes in a pile. I followed, my dick slapping up against my stomach. She stepped into the tub and spread her legs, looking back at me over her shoulder. “Do it. Piss on me like the dirty sister I am.” The first hot stream hit her lower back, running down between her ass cheeks. She moaned loud, pushing back into it. I aimed lower, soaking her pussy from behind, the yellow stream mixing with her own wetness as it dripped down her thighs. The smell was sharp, nasty, perfect.
She turned around and dropped to her knees, mouth open. “Give it to me here too.” I let go again, aiming at her tongue, her tits, her face. She swallowed what she could, the rest running down her chin and over her nipples. Her hand was between her legs, fingers working her clit fast while I marked her. When the stream slowed she grabbed my cock and sucked the last drops straight from the head, tongue swirling like it was the best thing she’d ever tasted.
We didn’t stop there. She stood, pressed her piss-wet body against mine, and kissed me hard, sharing the taste. I pushed her against the tile, lifted one leg, and slid into her soaked cunt in one thrust. Every stroke made wet, filthy sounds. She kept begging for more piss, so I pulled out, let another hot gush cover her mound and my own cock, then shoved back in. The extra slickness made it even dirtier, her walls gripping me tight while urine and her juices ran down both of us.
We moved to the floor of the tub. She got on all fours and I pissed across her back again, watching it cascade over her ass and down to her pussy. Then I was inside her once more, pounding hard, one hand reaching around to rub her clit while the other held her hip. She came first, shaking and cursing, her orgasm squeezing me so tight I almost lost it. I pulled out just in time to cover her ass and lower back with thick ropes of cum, then finished with one last long piss that washed everything down the drain in a filthy mix.
Afterward we stayed on the wet floor, breathing hard, her head on my chest. She looked up, smiling lazy and satisfied.

“Next time I want you to drink mine too.” I just nodded, already hard again at the thought. The weekend had only just started, and we both knew the house was going to smell like sex and piss for days.
