Unconditional Lust Ch. 02.1

*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.

They decided to watch a movie together, but ended up falling asleep on the couch until their mother returned. Together with their curvy mother they then watched T.V. and talked like they used to do before Jack left for college. They always had a good time. Cindy, their mom, was a great conversationalist, and since pulling out of her depression she'd become her old self again and was always very cheerful and upbeat. She'd begun dating about five years ago and was always out looking for another man who could make her half as happy as their father, George, had done; it wasn't easy.

Jack felt for his mother, she had to be immensely lonely, and with her two other children getting ready to head off for college as well it had to be nearly impossible to be this chipper. She was a very strong woman, and beautiful too. Though she was in her early forties, her face still had a rather youthful appearance to it, and she kept her coarse, wavy hair short and curled around her ears. It was a very good look for her. She also had a double D cup, which Jack had learned early in his horny childhood; Rose's panties weren't the only ones he'd stolen to blow his load into. Her waist was still relatively slim, and her hips were wide and child-bearing, with a healthy, plump rear that didn't appear to sag at all.

Eventually though Cindy had to get ready for a date that night and as she left she gave them each tender kisses on their heads and told them not to wait up. They were alone again, for the entire night, but Rose told Jack that she had something she needed to do and so he told her it was fine and that he'd just go pick up some groceries. After taking a list he headed out.

About an hour later he returned with four bags and carried them into the apartment himself. It was dark outside now and when he entered the apartment, it too was dark. Flicking on a light he moved into the kitchen and began putting everything away. Just as he was finishing Rose appeared in the doorway; naked.

"Why hello," Jack purred, his eyes appreciating her supreme figure just as they always did. "What have you been up to baby?"

"Oh, nothing," she said, with a mischievous smile playing on her lips and a twinkle in her adorable blue eyes. "I've got a surprise for you," she admitted with a nervous laugh. "But you have to put this blindfold on, okay?"

Jack laughed, a little nervous himself, "Well, alright, but this better not be some sort of trick." Though he wasn't sure, he thought this could possibly be the moment he'd been waiting for.

Quickly she produced a blindfold from behind her back and tied it around his eyes tightly. Everything became dark for Jack, but he was hurriedly led from the kitchen to what he knew was his sister's bedroom. She told him then to undress and he did so quickly. His cock bobbed out of his underpants, because it was already fully hard and incredibly thick. The anxiety was killing him.

His sister guided him up onto the bed and then told him to wait a moment. He was on his knees on her bed, and sat there with his hands by his side for a minute. He heard something open and then Rose was squirting something. He could hear her spreading the stuff for a few seconds and a light moan escaped her lips. Jack shook a bit, his excitement rising because he knew what was coming next.

"Alright," Rose said, and Jack felt the bed moving as she shifted. Then her hand wrapped around his cock, pumping it back and forth, while also lubing it up. She pulled him forward until his thick meat connected with what he could only assume was her crack. She pushed his cock against her crack harder, the loaves of her pert ass engulfing his head, and he pictured that tight little brown pucker and bucked his hips forward reactively, pushing in a bit more. She moaned, and he felt his cock twitch. He pushed a bit more and grasped her cheeks to pry them apart.

His cock was pushing into that tight pucker now, he could feel it as he eased forward. He could feel her ass give way to him, and then it pushed itself open and his fat, mushroom head popped in before it clenched tightly around him, as if trying to suffocate his prick. It was so tight, and slick. The lube had loosened it up nicely and Jack began to ease his way in to the sound of Rose's encouraging moans. His hands dug into her backside, prying it apart more as he pushed at least half of his meat inside of her dirty back hole.

"Shit!" He moaned, appreciating the irony of that particular word, "You're so fuckin' tight!" His hips pulled back now, then he eased his meat back in.

Rose moaned loudly, "You can speed up Jack, it's fine."

He did just that and began pumping back and forth a bit faster, sinking himself as deeply into her bowels as he could. His speed continuously increased until he was genuinely fucking her asshole, and enjoying the tight brown canal immensely. He knew he would cum soon.

"I'm about to blow Rose, you want me to fill your ass up with my cum?" Jack never stopped to think about why he was still blindfolded.

After a moment's hesitation Rose moaned, "Mmmm, yeah, fill that hole Jack. Fill it up with your hot, white spunk!"

Jack was happy to oblige, he was so fucking close, but first he reached down beneath his sister to rub her clit and push her over the edge with him. As he reached around her lithe body he grabbed ahold of her thick veiny meat. Her thick veiny meat? Jack immediately released her ass and ripped the blindfold from his eyes.

The lights were on and his sister was sitting at the head of her bed with her fingers sunk deep into her cunt, fucking herself furiously as she watched him with glazed eyes and a self-satisfied smirk. He then looked down and saw his blonde headed brother, Roger, looking back up at him, panting and his eyes filled with lust. Jack came, his balls clenching hard causing his cock to erupt into seven huge loads of thick white cum which burst deep into his little brother's asshole, filling his bowels with salty spunk. As he came, panting heavily himself, he still had his brother's thick tool in his hands and squeezed it reflexively. Then he felt the thick meat begin to throb and pulse before it began spilling a huge orgasm all over the bed.

Meanwhile, Rose's back was arched high, and her hips were shaking as she buried her fingers deep into her cunt, riding out a very powerful orgasm. Her orgasm was pulsing out around her fingers, down her ass and thighs, and onto the sheets as well. Together the three of them rode out intense orgasms until the collapsed amongst each other. Jack dirty, flaccid cock slid out of his brother's ass as he fell onto his side and then rolled onto his back. And Roger just lay there in his own pool of cum, ass leaking, and his chest heaving. Rose soon moved down to snuggle with Jack and looked up at him from her customary place under his armpit.

"I'm sorry I tricked you. I felt sort of bad when you asked me not to," She smiled cutely in an attempt to melt his heart.

"It's okay Rosie. I guess I can't be too mad, but I had a question. What the fuck?" Jack asked in a joking tone.

Roger rolled up onto his side then, "I'm sorry Jack." He said, his voice filled with sorrow. "You know Rose and I tell each other everything, so she knew I was bisexual, and when she told me what had happened I admitted that I felt the same way about you that she did and wanted you to fuck me just like you fucked her. So we devised this plan. Please don't be mad with me. I love you Jack."

Jack had never considered himself bisexual at all, but he admitted that one asshole felt just like any other, he hadn't been able to tell. And a nice thick cock in his hand had felt rather good, especially when it was erupting. "It's okay Roger, we can talk about this more later. We all had fun in the end though, so lets just get some sleep huh?"

The other siblings agreed happily, giving their brother a kiss on the cheek each. However, just as they were getting ready to curl up together they heard a gasp from the doorway.

"What in the world is this?" They all heard their mother exclaim.
