It was time. My dick couldn't get any harder.

I pulled out, still with a healthy coating of female nectar on my shaft. I dipped my hands to her sopping wetness and spread even more of the natural lubricant around her asshole. I was going to have to acquire some Astroglide after this. And then I'd placed the head of my cock at Ellie's anus.

“Ohmigod, ohmigod, ohmigod,” Ellie gasped. And then she felt the pressure as I leaned in with my hips.

“Push it in, baby!" Ellie cried. "Put it in my ass! Fuck my ass! Fuck it!

And then I pushed. Like everything else, I knew Ellie wouldn't want me to just slam my cock into her. Not on the first try, at least if I ever wanted to have a second try. So with some constant pressure and Long exhalations from my girlfriend's end, the mushroom head finally popped through.

“FUCK! I didn't know it could feel so BIG!"

I stayed there and let Ellie get used to the feeling. And after I saw the knots in her shoulders begin to relax I pushed another inch in. And then another. Slowly and methodically, I got my entire rod embedded deep into Ellie's bowels. I'd heard guys brag about what it was Like to tap a cheerleader's ass.

It was everything promised and more.

It was so tight, so hot, I was on the verge of ejaculating right then.

But fortunately, the slow descent had given me a breather and I managed to hold back. I wanted to enjoy this a little more.

“FUCKING FUCK MY ASSHOLE!!!" Ellie yelled. Then she just planted her face into the mattress and reached one hand between her legs to frig at her own clit while I backed my shaft out three or four inches before pushing it back home. I did this a few times, soaking in the feelings, and listened to Ellie panting, “Holy shit! Holy shit! Holy shit!"

It was then that I realized I wasn't hearing noises through the wall anymore. And on instinct, I turned my head left and right trying to strain my hearing in a different direction.

That's when I saw them.

Well, I'd like to say that I saw Danielle and Cherys standing by the doorway, watching us. While it was technically true, what my eyes focused in on were Cherys' PERFECT tits. That's the "them" that I saw.

So big. So round. The perky nipples were dark and smaller than I'd imagined, which made the globes appear even larger. And then my vision expanded outwards until I saw that she was standing not three feet away from me, fully nude. Her legs were just as toned and lithe as I'd thought they'd be. And to my utter delight, I saw that she was shaven completely bare. It was the first time I'd ever seen my goddess completely naked.

And then I realized Danielle was standing right next to her, completely nude as well. Likewise, it was my first time seeing my sister naked, and I couldn't help but notice she was shaved as well. Her naked tits were about the same size as Ellie's, large enough to be a pleasant handful. And her toned musculature instantly made me wonder just how athletic she was in bed.

ALL of this stimulation was simply just too much for me. I was embedded in my girlfriend's asshole for the first time. And I was staring at two forbidden, naked beauties: one the woman of my dreams and the other my illicit sister. There was no way I could hold back.

My steady pumping motion became a roar of power pistoning as I gripped

Ellie's hips and just started pounding her with everything I had. Ellie shrieked a metronomic "Fuck! Fuck! FUCK!"

With her face still half-mashed into the mattress in the wrong direction, she had no idea the others were in the room. But her twiddling hand and my cock filling her ass sent her into climax, and on that last "FUCK" she quivered and came.

Her ass muscles clamped down onto me, and that was all the restraint I had left. I pushed myself balls deep one final time, and ejected every ounce of fluid I had in my body.

Ny back was tensed, my butt was clenching, and I was spewing a torrent of cum down into Ellie's nether regions. My head was thrown back and I screamed at the power of my most intense orgasm ever, and still my dick was spitting out wads of semen.

An hour passed. No, not really. But it was a fucking long time. And then I was finally done. My legs were about to buckle, and slowly I pulled out of Ellie's abused ass as I sat down on the bed, still ina kneeling position behind her.

Ellie panted, her entire body covered in a fine sheen of sweat. Her dilated anus stayed obscenely wide open, and as she lowered her torso down towards the bed I saw a trickle of white cream bubbling out of her.

Cherys' eyes were entirely on her sister. Quietly she stepped up and touched a hand to Ellie's shoulder. "I can't believe you did that."
