*Thanks to everyone for their comments. Its been around a year since I posted this and I apologize for the long gap in between chapters. Life has gotten in the way, but now I feel like I have some time and inspiration to work on this and others. I reread my first chapter to get ready for this one and I apologize profusely for how bad the grammar and typos were at some points. I'm a bit mad at myself for not checking it better. I promise this next one will be quite a bit better. Hope you all enjoy! Don't forget to leave feedback. And I'm sorry for its length. I cut it short so that I could submit it, and would be encouraged to finish this chapter and continue it from there.
Note: Contains watersports and bisexual encounters.*
It had been over a week since Jack and Rose had consummated their love for one another in that brief night of passion. Since that encounter they'd fucked like rabbits, trying new and different things with one another and simply immersing themselves in pleasurable and sinful acts, to the point of nearly forgetting to eat some days. Jack had probably never been happier in his life, nor more tired, than he had been over the past week. Sadly, however, their mother was home now and so they had to put an immediate halt to their rabid sexual adventures whenever she might be even near the house.
She was gone for three hours on a lunch date with some friends currently though, and so Jack was laying on his back in his empty bathtub with his enormous erection pointing straight up into the air, his hand wrapped around its base. His long legs had to be thrown over the side of the tub, just so that he could fit. Standing over top of him, or more so squatting, was his gorgeous sister Rose. Her toned tummy was scrunched a bit and her tits were hanging due to her hunched position. Her small left hand was securely gripping the side of the tub, while her right was reaching down between her legs to pull her meaty cunt open erotically.
The two of them were looking into the other's eyes with longing, and for anyone who walked in it would seem that Rose was about to plop down on her brother's fat cock and fuck the shit out him. Her cunt was a mere three inches above his throbbing pecker and already glistening with her nectar. However, today they had decided to try something new, something they both wanted and that they'd discussed several times previously but never gotten around to. As soon as their eyes darted down to their groins Jack let out a long, heavy moan as the tip of his prick erupted into a strong torrent of piss. The pale green liquid shot straight up and onto his sister's pussy, spraying in all directions as it collided with that beautiful pink flower.
They both groaned in extreme, erotic pleasure, watching the dirty act with eager eyes. Then Rose grunted, her blue eyes squinting sharply before her piss-covered slit erupted into its own geyser of yellow liquid. Their piss streams collided briefly and sprayed them both with their excretory mixture before Rose began peeing directly on her older brother, and father figure's, pulsating cock. The pleasure this brought the pair of siblings was immense. They both watched as they emptied their bladders on one another, and Jack began pumping his meat up and down as his stream began to die. Meanwhile, Rose had been lowering herself more and more, and before either had finished peeing she sunk her smooth cunt down onto her brother's meat and engulfed it easily. He was still peeing inside of her, and she almost felt like she would come already.
Sheathing her brother, she was still pissing into his pubes as she began twisting her hips, but soon her pee died down and she began bouncing and twisting on her brother's cock, albeit a bit awkwardly due to the somewhat confined space of the bath tub. The two of them had a tendency to fuck in silence, just their grunts, moans, and cries of ecstasy adding to the sound of Rose's sloshing cunt. They had an unspoken bond and knew what the other was thinking without words, but at times they liked to talk dirty to arouse one another further.
This was one of those times for Rose, "You like fucking my piss-filled slit Jack? You like pissing in your baby sister's pussy?" She was almost close to an orgasm and knew Jack was as well.
"Mmm, fuck!" Jack growled and began pumping his hips with extraordinary strength, pummeling Rose's gash even as she rode him. "Fuck yes Rosie! I should have just fucked you while I filled your slutty cunt with my hot piss!"
"Oh, shit Jack! I'm cumming! Fuck! I'm cumming all over my brother's fat cock! Cum inside of your little sister Jack! Oh I love you so much!" Her cries became intelligible as that tight cunt began clenching and convulsing on her brother's shaft and she forced herself down as far as she could go. Her body tensed and her huge orgasm ripped its way through her loins. At the exact same time Jack pumped up into her as far as he could reach and she felt him start shooting big thick loads into the back of her canal, filling her up with load, after load of hot, sticky cum. She sat there for over a minute screaming out the pleasure of her orgasm as it continued for one of the longest moments of pure ecstasy she'd ever experienced.
Once her climax had subsided she collapsed atop her brother, smearing their piss-covered bodies together and simply trembled in his arms, cock still lodged between her lips. They lay there for a while, just holding one another, but finally stood up and turned on a warm shower. They rinsed themselves clean, almost regretfully, and then Jack bent her over again and fucked her doggy style.
He still hadn't gotten a crack at his sister's crack, she was a little scared about that one, and it winked teasingly at him as he fucked her from behind. He wanted to pierce that tight brown pucker some kind of bad, but he respected her fears. He felt though, that it might not be much longer since they were trying all sorts of new things lately; as seen by their piss-fest. After filling her eager cunt up with another explosive load, they finished washing and then got out and dried off.
