Join in on the fun.

Haley looked over her shoulder and smiled at me as she teasingly wiggled her ass. I stared at her ass, which was barely covered by her bikini panties and miniskirt, until I heard her sister let out an unlady-like grunt. I looked up to see Emily bent over with her face down on the bed as Bill took her from behind.

"I guess we're going to be here for a while..." I shrugged in resignation and fished out my growing erection from my shorts.

As I walked up behind her, Haley pulled aside her panties to let me have unobstructed access to her soaking wet snatch. She let out a low moan of appreciation when she felt the tip of my cock push past pussy lips and down into her tight hot cunt. I rested my hands on her ample tone ass and pounded away, causing her ass cheeks to ripple with each hard thrust they absorbed.

There was no game of Greyhound -- no competition of who could bring their partner to the most orgasms first. We were just fucking for the sake of mutual pleasure. The girls were moaning and crying out to God while Bill and I were churning in and out of their pussies. Haley came at least twice before I finally felt my balls tighten.

"Ugh..." was all the warning I gave before I came.

"Fill my womb up with your semen!" she moaned.

I wondered if her sister knew of her fetish? If Emily did, she didn't react since she was too busy being hammered from behind.

I just stood there and let Haley's pussy massage my deflating cock while the two of us watched Bill fuck Emily a couple more minutes until he finally let out a roar and overflowed her pussy with his spunk.

"I guess we should finish packing," Haley giggled, reaching between her thighs to scoop up some of the leaking jizz to taste.

"I'll try..." her sister groaned, still recovering from the hard pounding Bill gave her.

Bill and I gave each other knowing nods and smirks.
