“Ugh, yes. Just like that. Now in and out a little. Tongue fuck my butt for me, baby.” Sam began work her clit more quickly, racing towards her next orgasm.
Bobbie had Samantha completely wound up again. She was twitching all over and hissing through gritted teeth. He also wasn’t shy about what he was doing anymore. He began to openly sodomize Sam with his tongue. Heather and I watched as his head bobbed in and out of her ass, his tongue speared to a point.
Sam held perfectly still and let him do all the work while frigging herself frantically.
Heather egged her brother on between gasps while I plunged in and out of her adolescent hole, “She’s… ready to … to cum now… Bobbie. Push your tongue… inside as far as you can.”
Bobbie listened to his sister. He pressed forward into Sam’s little rump, grimacing at the effort as he stretched his mouth to cram his tongue into her as deeply as he could.
It worked. Sam shook and came again, her tiny hips humping and twisting as she peaked. She was reduced to several small soft grunts as her orgasm racked her little body.
But that had just been the warm up.
Samantha was still rubbing herself through her final shudders when she arched her back severely to push her ass higher. She was so damn flexible that her belly and her butt were nearly perpendicular. It was a submissive pose and she openly begged Bobbie to take the next step.
“Okay, lover. Put your cock in my ass.” She shivered a few times, still not quite finished coming. “You’ll love it, I promise.”
Bobbie was up on his knees behind her in an instant. His cock was drooling pre-cum. Between her saliva-soaked butt and his dribbling fluids, they had plenty of lubrication. Heather and I watched her brother nudge his knob between Sam’s ass cheeks. Sam reached back with both of her hands to lewdly spread her own ass open for him. We all watched his tip push against her backdoor.
“Slow.” Heather and Sam both cautioned Bobbie at the same time.
Their perfect, stereo warning made the three of us chuckle. Everyone except for Bobbie. He was completely absorbed in the contact of his cock and Sam’s butt.
Like I had told him in the kitchen, she was taking Bobbie right to the advanced class.
We all looked on breathlessly as Bobbie breached Sam’s ass and his glans slowly disappeared into her rear. Inch by inch, his shaft slid into her tiny upturned butt. Sam was well-experienced with my thicker than average cock. She was also relaxed from two orgasms and Bobbie’s thorough rimming. It meant that Sam could let him penetrate her in one long glorious push. It was a sight to behold – nearly eight inches of teenage cock slowly swallowed up by Sam’s miniscule rear hole.
When he was buried completely in her ass, Sam cocked her head to grin back at Bobbie. She still held her tiny ass cheeks open so that he could appreciate the view of his cock crammed in her petite rump.
“Feel good, Bobbie?” Sam purred.
“The most amazing feeling ever. You okay, though?”
She chuckled. “Sweet of you to ask, but I’m fine. I’ve done this a few times before. Ready to fuck me?”
