“This does not include personal trainers, they cost extra.” The girl at the desk said as I filled out a form. She took my debit card details and g...ve me an invoice. For two days I went, concentrating on the running machine, thinking it would get my weight down. I could see from the corner of my eyes a girl watching me. I could not help but look at her while she was watching me, she was obviously an extremely fit woman. By the end, she seemed to have enough of watching me and accosted me outside. She was playing with her pussy and telling him how to suck my cock. He was kneeling there sucking my cock as directed by her for only a few minutes. She was on fire. She got up and demanded that he fuck her. She lay down on her back right there on the living room floor. He joined her on the floor and began fucking her. He came very quickly and she was pissed. I knew that it was up to me to salvage the situation. As her husband got up from fucking her I dove in and started licking her pussy. She. I awoke the next morning and swore I could still smell Cass's butt stink on my upper lip and rubbed a quick one off before heading down to the kitchen. At some point during the night Cass had gotten up and gone to bed, leaving her dinner in the microwave. She got up an hour or so later and carried on as though nothing had happened! She was none the wiser to me smelling her ass the night before! Needless to say I couldn't wait until the next time she passed out on the couch! I didn't have to. As the door opened wider, a funnel of light from inside brushed their profiles. Her heart thumping against his, Rosie moved Matthew deeper into the shadows, careful not to make a sound in the gravel underfoot.Despite the gravity of the situation, Matthew couldn't resist reaching between her legs, an errant thumb finding that the crotch of her panties was soaked through. Though she tried to act to the contrary, Rosie, it seemed, was getting off on the thrill of discovery as much as her partner.
