The girl at the desk told me that my new membership included instruction from a personal trainer at no charge for the first thirty days. We discussed ...he details and I signed up to start with a trainer the following week. I made my appointment for late in the evening so I could come in after work. I met Antonio, my trainer, the first night. He was a very fit guy that most women would drool over. He was in his early 30s, average height and Latin. Antonio showed me the equipment that I was not. Gina kept him on tenterhooks for about fifteen seconds, then she said, “OK!” and stood up.She pulled the top over her head with astonishing speed, but then she was like that, Gina, once she’d made up her mind. It was all Ben could do not to drool. He’d tried to envisage Gina’s breasts many times, and what he could see of them inside the snug, black lace bra was better than any fantasy. She had her hands behind her back and he said hastily, “Not so fast, Gina! You look really hot like that!. If anyone saw us, I will be the talk of the hospital. Now, eat your sandwich and I will see about getting your paperwork together."She went out the door, leaving me standing in the room, wondering what the hell had just happened. I went to pick up the coffee and noticed my hands were shaking. Damn, I needed to stay away from her if she did this to me with just a short kiss. I sat down on the edge of the bed, fumbling with the sandwich until I finally got it unwrapped. I ate it on automatic. Emily pulled away from our kiss and flattened out on her back as Chrissy pulled her legs apart and shoved his big cock into her throbbing pussy. Emily and I were lying next to each other getting fucked. We turned our heads enough to kiss as the four of us fucked each other.I ventured a glance and I could see that Jessica and Chrissy were kissing and fucking us at the same time. Emily went into an orgasm first, "Oh fuck Chrissy your cock is so fucking big, fuck me harder. Slam that fucker in me..
