All Richard could get out was a weak groan.
“Aw c’mon,” she pressed herself against him, “parts of you want me. We can both feel how hard you are,” she said softly. “I think we just need your brain to catch up. How about this? I’ll beg you. I’ll beg you to do it. I’ll beg you until you have to say ‘yes.’ Would that make this easier for you?”
She ground her fabulous rump back against him eagerly and her voice took on a hungry, plaintive edge he’d never heard before.
“Please do it, Richie. Please take my little bum. Please? I want you to. You were the first boy to kiss me and the first one I showed my new breasts to. I let someone else take my real cherry so it’s too late for that. I’ve… I’ve regretted it ever since. But this… I still have this for you. You’d be the first man there. My big brother could still come first.”
She took a long slow dramatic breath.
“Pleeeeaaaaaase?” she mewled softly, like a kitten that hadn’t been fed.
“You mean like, now?” he finally managed to speak.
“Yeah, it felt really good this afternoon. And it’s so warm out right now. I just had a nice long and satisfying shower. I even had a good stiff drink too. I feel relaxed and horny in a slow, lazy kind of way. I can’t imagine a better mood to be in.”
His willpower evaporated. “Okay. Bedroom. Let’s go.”
“Uh uh, out here.”
“On the patio?”
“Yeah, I want to be with you for the first time just like this. With the sun on our skin and the breeze in our faces. It’s perfect. So, uh, how do we do it?”
“Stick your tush out. And drape yourself over the railing.”
He knelt down behind her and slowly drew the yellow fabric of her sundress up, unveiling her gorgeous sleek runner’s legs and her spectacular miniature butt. It was framed in a tiny, white thong that disappeared into the tight cleavage formed by her little buns.
He folded the fabric up and onto the small of her back then leaned in and planted a smooch on his sister’s ass. He could see the tiny, bare bulge of her naked mound too.
She smiled and reached around to pat his head, “Funny, I’ve been telling you to kiss my ass for years, Scooter.”
“I’ve been wanting to kiss your ass for just as long,” he slid the thong down her legs and off, tossing it away.
She shivered as his tongue traced circles up and down and across her upturned cheeks. She moaned when he nuzzled into her crease and began to lap at her virgin rose.
“Ooooh, that’s nice,” she cooed, “keep doing that bro?”
He rimmed her for several minutes until she was gasping and he couldn’t wait any longer. He stood and jerked his pants down then pressed himself against her, humping his shaft up and down between her cheeks, drooling precum into her crevice.
He centered himself on her tiny hole and watched her grip the deck railing so tightly her knuckles turned white. He pressed himself inwards as slowly as he could but she still struggled.
“Ugh,” his little sister groaned, “easy Scooter. I’m new at this, remember?”
“Sorry,” he winced, “my fault.”
“Wait, first…” she reached back and her small hand wrapped around his cock for the first time. He nearly came right then. It got worse when she angled him down slightly and rubbed him against her smoothly shaven pussy. She pressed him inwards more and more firmly until his tip spread her smooth little lips and he felt the entrance of her vagina suction onto him hungrily.
“Sis?” he said with confusion and he felt himself sinking slowly into her pussy. This was not what they’d talked about.
“Shhh… I just want you nice and slippery. I’m soaking wet. Handy huh?”
She humped back against him, forcing his cock slowly into the wet, clutching heat of her teenage sex. It made his knees buckle. His cock was in his sister. Inside her. She kept pushing back against him and his shaft slowly sank deeper. They both groaned as her slender body opened up around him until his hips met her ass.
She was tight, incredibly tight. In a crazed moment, it occurred to Richard that Chip must not be fucking her as often as he should have been.
They humped together several times. He nearly forgot about everything else as he gripped her narrow hips and drilled himself in and out of her little body. Her insides sucked at him and she limberly rotated her tiny ass in his crotch, swirling him deep inside her and cooing appreciatively with each of her brother’s thrusts.
Somehow though, Lizzie didn’t forget their plan. She slowly pulled herself forward far enough that he popped free of her clutching tight pussy.
“Okay,” she hissed, “now do the other thing. Hurry? Before I lose my nerve.” She bent over the railing more deeply and curved her ass higher into the air, swishing it back and forth.
He pressed himself into her crack again. He felt her opening spread slowly as he drilled himself firmly against her little star.
“Guuh,” she whimpered as his cock began to win its struggle and his tip slowly sank into her. Her knees shook crazily with the force of his invasion. Still, she bravely pressed herself back into him, driving another inch of his shaft into her rectum until she couldn’t bear any more.
“Wait… need… don’t move,” she hissed and stopped for several seconds before nodding for him to continue. Richard gaped down at the vision of half his cock wedged between his kid sister’s ass cheeks.
“Okay, more,” she finally whispered. Together, with a few pauses for her to catch her breath, they painstakingly worked his cock into her virgin asshole.
“You okay, sis?” he said when he was buried inside her.
