I was actually getting a bit jealous of Dave seducing my wife, or visa versa. We came on this vacation together and I was spending my time with anothe... mans wife. A gorgeous wife, but still another mans wife. "Come on Mike! Let's go sing," Linda suggested, pulling my hand. "Are you guys coming?" I asked, hopefully. "Oh yes we will be cumin! We are going back to the room," Dave said, with a suggestive smile. Linda and I headed out to the Buckaroo Room, leaving my hot wife and Dave to sing. Another difference between the sisters, she noticed immediately, was their bodies. Though they had similar proportions, their builds were entirely dissimilar: Christine was soft and round while Darla was sinewy and tight. Lisa watched closely, the cycle of those muscular lines flexing and relaxing really made her wet. She was looking forward to finding out all the other ways the sister were different."Fast learners," Lisa said. It may have come out loud enough to be heard, but that ultimately. She threw her head back one last time before her river of love honey flooded my face. She slid back down my body, leaving a trail as she kissed me long and hard on the mouth. She reaches for my manhood, to find it still HARD,HOT and THROBBING.It dances as she gentley strokes it with her finger tips. Working her way down my body,she leaves soft kisses where her tounge as been. She is driving me crazy now. And she knows this! As she reaches my manhood,she paused for a moment to look at me and. I pulled down my shorts and boxers and threw them on the ground, my dick already firm and erect, jerking as more blood flooded to it. The feeling of being naked out in the open, and the naughty fantasises I had about those two, young hotties made me increasingly horny. I started to stroke the shaft and rub the tip, and closed my eyes, imagining how those young, firm tits looked under their bikini tops. As I tugged my cock more firmly, I fantasized about how it would feel like to touch those.
