“Barely. I hope this gets better soon,” she gritted out through clenched teeth, “move a little bit, let’s see.”
“Uuuugh,” she grunted when he pulled out slightly and pressed back into her ass. He felt bad for causing her discomfort but not bad enough to keep from cumming. Early. And hard.
He couldn’t help it. He’d gotten overexcited. But who could blame him? His own sister was bent over in front of him and he was balls-deep in her gorgeous little nineteen year-old track star butt.
“Are you…?!” his sister’s head whipped around just as he began spewing cum into her straining rear hole.
They had taken several minutes to so slowly and carefully wriggled his cock through her miniature sphincter only to have him cum almost instantly. She looked back at him in amazement as he continued cumming. He streamed more than a dozen giant spurts into her ass, bathing her struggling insides.
“Wow,” she grinned back at him, “aren’t you glad you saved it all up?”
“Ahhh, so that’s what that was all about,” he shook his head.
“Mmmhmm, I wanted a nice fireworks show for my first time,” she half-smiled. “It was over pretty quick though wasn’t it Scooter? Is it supposed to go that quick?”
“No. I’m sorry, it’s been awhile since I’ve had sex and I’ve been really worked up and this is just totally totally fucking hot.”
He bent over and rested his forehead against the soft, tanned skin between her shoulder blades to try and get a grip on himself.
“Guess it feels pretty good in my tushie, huh?”
“You have no idea. Just gimme a sec, sis. If you want, we can keep going. There’s no way in hell I’m going soft inside your perfect little butt. ”
She swished her ass back and forth experimentally, wincing slightly. “Ewww, it’s all warm and slippery inside me now. It’s actually… actually kinda cool.”
She made an even funnier face as she wiggled herself a bit more on him. “You know what? It’s actually better like this.”
“Well, there’s plenty more where that came from.”
“Good,” her bright eyes locked onto his with a serious determination that he’d never seen before, “’cause I want it all, Scooter. Everything in you. You’re going to do me again right now to run your nuts dry. Then we’re going to go to sleep in my bed. And when we wake up, I want more of this before either of us say ‘good morning.’ Got it?”
She twisted her neck and he craned forward to meet her. Her lips dissolved into his, tongue teasing him skillfully. She tasted like the gin she must have been drinking earlier.
“That’s it bro’, open me up. Open me up with that nice thick tool of yours.”
“Feeling better?”
“Meh, at last it doesn’t hurt anymore. It’s a start anyway.”
“But not feeling good either?”
“Uh uh. Still, it’s crazy hot knowing that it’s my big brother’s noodle that’s buried in my butt.” She looked back at him and smiled. “You going to come again, stud?”
“God yes.”
“Good. So far, I like that part the most.” She reached back between her legs and he felt her small hand gently fondle his swinging balls.
As she caressed him, he sawed in and out of her rectum, watching his shaft disappear and reappear between his sister’s little ass cheeks. He lasted all of another five minutes before he came again, jetting another enormous load into her ass.
This time, he gently eased himself out of her and stepped away. His sister stood up carefully and stretched her back, moving slowly and stiffly. She’d been bent over the entire time. Her dress slid back down into place to cover her and she turned to face him and leaned back against the railing to steady her weak legs.
“Whoa,” her face screwed up cutely, “I can feel all of your stuff. Up inside me. It’s kinda crazy. Kinda hot too.”
“Really?”
“Yeah, I’m getting turned on. A lot. Wow. I think I actually could make myself… I think I need to…” her hand slid down and under the front of her dress. Through the thin fabric, he watched her cup and twirl at her mound eagerly.
“Go ahead, Lizzie,” he said softly.
“Here?”
“Sure, why not?”
“Right in front of you again?”
“I don’t think now is the time to get shy.”
“Good point, I mean, I guess after what we just did.”
“Mmhmmm.”
“Well, when you put it that way…” she began to touch herself more urgently. Her lips curled up cutely, “Eeew, it… your stuff… it wants to come out. I gotta go. I’ll be right back.”
She leaned away from the railing.
“Uh uh,” he steered her backwards to a little table on the patio and leaned her against its edge instead, “Stay. I want to see.”
They both heard a drip of semen fall from beneath her dress and onto the patio with a small splat.
Liz groaned and slipped her hand under her dress again, rubbing herself harder, “Ugh, this is nasty Scooter.”
“Nastier coming out than going in?”
“Uh huh,” she whimpered. He watched a small stream of cum appear on the patio again, “Oh wow, wait, there’s still more. Jesus, bro… so much cum.”
Another dollop followed.
“… oh god… Scooter…?” his sister mewled, looking at him through slitted eyes.
What followed was the rawest, nakedest, most beautiful thing Richard had ever seen. His kid sister herked and jerked and frigged herself in front of him as his cum leaked from her no longer virgin ass. The well-toned muscles of her legs quivered and her breasts shook beneath her little dress.
“Guh huh huh huh,” Lizzie rolled and wretched as her orgasm approached. “… fuckfuckfuckfuckfuck…” she whimpered, hunching into her own hand and shaking her head as her climax seized her slender body.
“Aaaah aaaaah,” she finally wailed as she peaked and one long last string of semen dripped out of her and down onto the patio. Her face scrunched up and her body curled in on itself and shook for several long glorious moments.
When she finished, her head hung loosely from her neck, drained completely by the entire experience.
He let her catch her breath, then took her hand, “Come on Lizzie, let’s go get showered up again.”
She nodded weakly. He left the lights off and led her into the darkened bathroom. He undressed them both in the thin light, rinsed her off in the shower, and dried them both. They slipped, exhausted, into bed. Dinner was long-forgotten.
