They should head home

"Sorry, you're right, I don't know what I was doing," he says, blinking in confusion and holding a hand to his head. He shook it off quickly. "Anyways, I think we should go home. I don't think its good to be out right now. Plus, I feel a little weird."

"What happened to the cops getting statements?" Rachel asked. Parker shook his head.

"There were enough people who ran out for them to get an idea of what happened. Plus everyone inside too. We wouldn't be any help anyways. So let's just head home, my head is pounding."

"A little too much to drink, brother? I saw you down your last one right before we all started dancing," Rachel laughed, happy to feel like everything was normal after what had happened.

"Maybe..." Parker said, unsure. It didn't feel like that, but who knew? They quickly paid for the water, ordered an Uber, and were on their way home, only a short drive away.

"We're back," Rachel called when they got home. Their mother, Arielle, came out of the kitchen, drying her hands on a towel. She was a beautiful woman even at 46, her hair a slightly lighter blonde than her children's. Her form had remained largely trim, despite carrying twins and another child, her breasts and rear giving her a mature, MILF-ish appearance.

"You're back early," she said. "I didn't expect you back until much later."

"We decided to come back early. There was some real freaks at the club, so we left and decided to just come home," Rachel explained, slipping her heels off. Neither of the women noticed Parker carefully watching them, desire bubbling in the pit of his stomach.

"Are you going to stay up at all? I feel bad if you just go to bed on your birthdays," Arielle said, tossing the towel in her hands aside.

"I think I'm going to. The weirdos at the club really freaked me out. I'll tell you about it tomorrow. Right now, I just want to get out of these clothes and makeup." Rachel walked up the stairs heading for her room. Parker's eyes followed her thin swaying hips.

"I think I might stay up for a bit," he said, eyes darting between his mother and his sister.

"Sounds good," Arielle said, walking back into the kitchen. "Your father's asleep and your brother is in his room. Let me know if you need anything." Parker nodded and ambled up the stairs, heading for his room and shutting the door.

He immediately jammed his hand down his pants and wrapped his fingers around his stiff cock, jerking it fast. He had been positively boiling, for the past hour, ever since the orgy at the club broke out. If Rachel hadn't dragged him out of there, he probably would have joined in. But it stuck with him, ramping his lust up to intolerable heights. And now he could finally get some relief.

He leaned against his door, panting heavily as he fantasized about all the hot women at the club, imagining them bucking wildly on his dick. In his fantasy, one of the bartenders was deep throating him while another woman licked his balls. He pulled out of the cute bartender's mouth and immediately pushed his iron length into a pussy, pounding it hard. He fucked her until she orgasmed, at which point he switched targets, burying himself in a random brunette.

He kept up the pussy rotation until he was close to orgasm himself. In his mind, he made one last switch into a skinny, toned girl with dirty blonde hair. He fucked her with abandon, only interested in cumming. For whatever reason, she was more vivid than the other imagined women in his head. A second later, the woman turned her head and he saw he was imagining his twin sister. At the thought, he finally reached his peak and came, breaking him out of his fantasy as his cock spurted all over his room.

Not that he really cared. Parker was too busy thinking about his sister. He had been watching her all night, though he had told himself it was out of concern. Now, he didn't care about that or anything else. He just wanted to fuck her.

Ripping the door open, he stalked down the hallway with his dick hanging out to the bathroom, where Rachel was wiping her makeup off in the mirror, already changed into a pair of booty shorts and a tank top. Parker watched her for a minute, his desire ramping higher and higher as he stared at his sister's long legs and tight butt, emphasized when she leaned closer to the mirror. He considered for a split second that what he was about to do was wrong, but the idea was instantly replaced by the need to rut something female.

Parker slowly walked into the bathroom until he was standing right behind Rachel. "What's up?" she asked, wiping herself of the last of her mascara. Parker didn't say anything, too entranced by his sister's ass. His dick surged back to full size, maybe even a bit bigger. He grabbed the ass in front of him, ignoring Rachel's cries of protest and rubbed his member between her tight cheeks. Even through the fabric, it felt incredible, and Parker immediately needed more. He tore her shorts and underwear off and relished her smooth skin against his, holding her hips to prevent her from twisting away.

"Gah, sis, your ass is great. Not too big, but so tight and firm. I wonder if you're as tight everywhere else," he moaned, moving his dick between her legs.

"Parker, what are you doing?!" Rachel yelled. "Stop it right now!"

"I would," he said, wholly focused on his goal. He eased his cock further and further until he could feel the heat and moistness of her cunt. "But I...need...FUCK!!" he yelled, shoving his length into his sister. Rachel wailed at the intrusion, but Parker didn't stop. If anything, her cries drove him onward, pulling back and slamming back in. He **** Rachel to lay on the counter to get a better angle.

Rachel cried as her brother fucked her, moaning as her cunt instinctively lubricated itself and sent bits of pleasure through her. She couldn't help but watch herself be rutted in the mirror, her brother thrusting into her from behind. "No, Parker, stop!! Please! You can't~OH!" she moaned as her fear began to melt away, replaced by the feeling of mounting bliss. "This is wrong, Parker, just-OH FUCK-just stop. Oh god, you're so deep! Oh, oooooohhhhhh..." she trailed off as a small orgasm hit her, making her buck. She unintentionally pushed herself back further onto her twin's dick, igniting more thrills in her now slick cunt. Unable to help herself, she started to thrust back, meeting her brother half way as he continued to piston into her, grunting all the while.

"That's right, sister, it feels so gooood.... It's even better if you let yourself enjoy my big dick splitting you in half," Parker said through clenched teeth, his own peak approaching. "First I'm going to fuck you, then I'm going to go make us a little sister with Mom. If you're good, maybe I'll give you a baby too. You'd like that, wouldn't you, you slut?" He fucked her faster, turned on even more by her gasps and moans.

"YES! PLEASE FILL ME UP! Fuck me pregnant with your cum! I want to be a sexy MILF at 22!" she screamed, no longer able to deny the ecstacy she felt. Watching herself become more depraved in the mirror as she gave in only egged her on.

"You need tits for that though," Parker said, thrusting harder into his sister's undulating pussy. "No man wants to fill a woman up if she doesn't have any tits."

"Good thing they're growing then! OH, THAT'S IT, FUCK ME DEEPER!!" Rachel's orgasm broke over her as she watched her small tits fill out her tank top, going from small c-cups to bouncing DDs. The pressed against the fabric, her erect nipples poking out sharply though the thin fabric. Her hips widened slightly too, but not as much, retaining her small, tight ass. "See, I've got titties now, Parker! Now FILL ME UP WITH YOUR FUCKING CUM!!" she wailed, her bucking sending her new tits shaking.

"YES, TAKE IT YOU FUCKING SLUT! TAKE MY CUUUUUUMMM!!!" Parker screamed as he detonated inside his sister, shooting glob after glob of warm jizz into her tight twat. He hadn't noticed, but his own figure had improved slightly too, muscles gaining a bit of definition and his cock gaining an extra inch or two. He was too absorbed in the process of cumming as deep into Rachel as he could.

Finally, their rutting slowed as they came down, Parker's improved dick popping free of Rachel's freshly fucked pussy, both of them panting from exertion. Their lust didn't abate though, their minds instantly wandering to the other occupants of the house.

"Gonna go make good on my promise, fuck that MILF of a mom. Gonna breed her," Parker grunted, stroking his slightly abated dick.

"Hmmm, you do that, bro. Make her a sexy bitch like me. OH, my tits are so BIG now!" Rachel squeezed them in through her stretched top, the fabric thin enough to be barely transparent. "You think our little brother will like them? I'm going to go see if he'll give me a taste of his dick too." The two split up, Parker walking back downstairs stroking his cock at half mast, while Rachel strolled down the hallway her bare ass swaying seductively.
