I did my best to comply. And even when I was done shooting, Ellie's internal muscles were still tugging at me while her hips undulated beneath our bodies. For the first few seconds, my cock was way too sensitive and I started to pull out. But Ellie's legs locked behind me, her sneakers once again digging into my shirt to hold me inside of her.

I wriggled for a few moments but then the sensitivity began to fade and my half- hard erection was starting to enjoy the feelings once again.

The pleasure was coming back. Add to that how Danielle and Cherys were still going at it through the wall, and I was starting to feel up for round 2. Thank god for teenage recovery.

“Turn over, sweetie," I told Ellie. I pulled out and she rotated around until she was perched on my bed, her ass in the air with her head resting on her folded arms, her back angling down away from me. There was plenty of room for me to settle onto my knees behind her, and with a happy moan from Ellie's end, I slid my cock back home.

We were just getting into rhythm when a fresh conversation came through the wall.

“Ooh, you brought Fred, Cherys?" Fred was Cherys' dildo. I'd heard the name often enough. Only it seemed that my sister and Ellie's sister were speaking a little more loudly than usual. I imagine they were getting off on the knowledge that we could hear them.

"Uh, huh. And Fred's gonna split you open!"

“Unghh! You little bitch! I wasn't ready for that!" Danielle squealed.

“But doesn't he feel so good?"

“Unghh! Fuck yeah..."

“OHH! Damn you Dani! I wasn't expecting that!" Cherys cried loudly.

“You want me to stop?"

"No, sweetie. Fuck my ass with your finger! Fuck it!"

The vision that crept into my head sent a powerful jolt through my dick, a spasm that Ellie clearly felt. "You like that idea, don't you?" she asked me quietly.

The extra juice in my next thrust answered for me.

“Oh! David!" Ellie called out, loud enough for the others to hear.

“stick your thumb in my ass! Stretch me open! C'mon, get me ready baby.

Don't you wanna fuck my ass? Don't you want to put your big, thick cock down into my shithole?”

My eyes went wild as I really began fucking Ellie. We'd never had anal sex before. And I wasn't sure if she was just talking so that her sister could hear or if she really wanted me to fuck her ass. But I wasn't going to pass up the opportunity.

I paused from my pumping just long enough to dip both thumbs inside of

Ellie's juicing snatch. For a moment, she squirmed against the extra stretching of my thumbs along with my shaft inside of her. But then once I got them good and wet I pulled out and placed my thumbs at her crinkled rosebud.

I stopped my thrusting and Ellie went still, my cock still embedded in her pussy. And with gentle pressure and Ellie panting as she tried to relax, I managed to pop my right thumb inside of her.

The left thumb came soon after, and then I was tugging gently to the sides while I slowly pistoned my dick in and out of her soaked pussy.

“Ohhhh.... Ohhhh..." Ellie was whimpering. At first, her anus had clamped down around both thumbs tighter than anything. But the Longer I kept screwing her pussy, the more she was able to relax her sphincter.

And after a few minutes, her hole seemed to gape open just a bit on its own.
