I hid. The third rustle was louder still. Sneaking a peek was called for once again. To my surprise, not only were her legs spread and her pussy lips ...alling to me from the top of those divine legs, but now her blouse was undone, revealing a beautiful, proud nipple upon a firm tanned breast. Before I could stop myself, I heard a "Holy shit," echo around the coach.I blushed and tried to sink into the seat. My heart sunk and I though she would let fly. But no. Her right foot lifted up onto the. I know it would just be for the sex, the way it would be for me with another guy. I’ve never seen a live porn show but I’d like to.“Sheila will be easy to seduce. It’s practically a done deal as it is. Maybe we should start with a guy. The ad should be simple to compose.”“Let’s not lose the idea of another couple. That way, we can see everything at the same time.”“Oh, of course. But what if no couples answer the ad?”I laughed. “What if nobody answers our ad? That would be sad.” Gail laughed. I groan again as the pain in my ass starts to exhibit slight twinges of pleasure. The twisting and turning continues as my asshole becomes more accustomed with it. The pleasure twinges increase and I start to moan and groan quietly. On it's own, my ass starts to twitch and gyrate. I notice that I am becoming horny again.After a while, there is more whispering and the hand pulls back a little only to return with the thumb tucked in against the palm. My hole is being stretched again...further. ? I was starting to get nervousat that point because normally Mistress would have me strip naked in front ofher and then crawl naked to the pool.?But as the obedient kitten I am I obeyed her. When I got to her room, Iopened my little closest and picked out my black bikini with a halter top thatstopped just below my breasts and a string bikini bottom.When I got to the pool Mistress wasswimming around lazily wearing nothing. I of course was getting very nervous ofwhat Mistress had in store for.
