I was 19 at the time, and had a steady girlfriend for more than a year already - Serena was her name. We were very open with each other sexually, and ...ould often fulfill our fantasies, like doing sex-play in public places or dressing in costumes. We both loved to fuck and to explore ourselves sexually.Serena was hot, having nice sized tits and a big butt, kind of like J-Lo without the all the help money can buy. I loved to fuck her in the ass, and the night this story begins I was trying to do. She asked me if I wanted to see her naked, I nervous but said yes. She giggled as she pulled her pink sweater over her head exposing a blue lace bra, she threw the sweater on the floor, slipped her bra off and when it hit the floor I felt like my dick was going to explode, she has huge round boobs with light pink nipples, she looked at me and said "do you wanna touch?" I nodded because I could not speak, she leaned towards me and took one of my hands and placed it on her left boob, I started to. "I pressed on, "And didn't they often ask you to show it off?" Ofcourse!" He said, "But what the hell are you leading up to?" I have a friend," I said, "Who's a doctor and a night time teacher at the university." I'll bet you're a medical rarity, as well, and you could earn hundreds, just showing it off to some medical students. You might even get to try it ON a medical student!"I was trying to encourage him to expand his sexual horizons, lest he make me his 'bitch', and if he pressed me, I. I sat down leaning against my bed, and Doe came to me, and pressed her nose against mine. Her mouth was open a bit, and as I breathed in she licked my mouth. I thought it was funny that I had never thought of kissing a dog before, but anyways, I went for it. I opened my mouth and slid my tongue into hers, and pushed my lips right up against hers. From that point on I must say that its hard to describe and probably awkward to look at, and you need do do it a certain way, but I must admit that it.
