We would have sex maybe if I was lucky 3-4 times a year. I told her that I was Bi but preferred women. She said she was also Bi but preferred men. Tha... couple years back she worked as a Dominatrix was telling me strange things men wanted to do with them. That she made great money but wasn't satisfying. After a couple bottles of wine and dinner we made our way back to the hotel. We had embraced and began kissing I undone her skirt and slippedIt down, slowly undoing her blouse opening it exposing. Bowed elaborately as he spread it over the most even bit of the clearing, kicking litter away. Grunted as he removed his trainers, and wriggled out of his jeans: -Our fuckmat, dirtygirl. Still standing, her gaping cunt remained presented to him, her legs apart: -Slap your cunt, master. -Oh jesus… His cock rampant, his hand slapped her wetness and he watched her eyes turning up: -More, slap it harder. Your cunt… He watched in awe as her beloved face contorted to the blows. One arm went round her. Even though I had seen her completely naked, I was transfixed by her plump bottom and felt a stirring in my own shorts. If I hadn’t been so fucked-out, I would have horned in on Mark’s action. But as tired as I was, I was content to be a happy spectator…this time. She leaned forward again and pressed her tits against his body. At the same time, her hands moved between their bodies and in short order I saw the top of Mark’s shorts loosen. I couldn’t see from where I was sitting, but I could. After only about a month, I began realizing things about Jenna that I hadn't before. She became more interested in money, and material things than in me. I was beginning to feel like a sucker. One day I came home from work, to find Jenna's sister Kelly at our apartment. Kelly explained to me that she had lost her job, and she had nowhere to go. Of course, my loving girlfriend, generously offered to let me support Kelly. I was furious but I wanted to wait till Jenna came home and make her.
