At one point Kayla asked Mary if she had told me about their experiences together. I perked up a bit and Mary got real quiet and shy. Kayla was amazed...that Mary hadn't told me. Finally she said well if you won't I will. She went into great detail how on those nights when neither of the males were around how they would finger each other then finally eat each other's pussies to shattering orgasms. Hearing this got me incredibly excited. Mary took my cock out and started to stroke me. I told her. My back was to the shower wall so there was no where to go except down my throat.I took it all and it was getting jammed down my throat as the Married Guy thrusted. I pulled his balls out of his speedo and held on to them with my left hand to hold him back from impaling me on his cock. My right hand was stroking the bottom half of his manhood alternating as my lips took it in, and out, and in, and out.The Married Guy was better at being quiet than I was just minutes earlier, his cum exploded. Tonight, if he didn’t freeze to death first, he’d have her and complete his private little ceremony with her, and fade off into the dark night. They’d find her later but there would be absolutely nothing to connect the two of them. He put his weight on one foot first and alternated with the other in a somewhat vain attempt to keep warm. There wasn’t much chance of success on that front unless he could find a way to a spot closer to the fire without being noticed. Without being noticed, that was. It was extremely hot sucking two nipples into my mouth at the same time. While they rubbed their nipples together I stuck my tongue between them, flipping their nips up and down. Feeling both their nips pressed together as I sucked on them was quite sensual. The no touching rule had gone a bit further! As they rubbed and we sucked, Erica held Lacey's hips, and Lacey began to press her leg between Erica's. Watching her press her leg further between Erica's thighs gave me an idea for my next.
