I had no important lectures in college from Monday-Wednesday so I planned to take a holiday and execute my plan & fuck Poornima.I was sitting in my to...wel watching porn to get a hard-on when the bell rang. It was Poornima & I was ready to execute my plan. I opened the door, she was shocked to see me in a towel only & I ran towards my room acting like I didn’t want her to see me like that & that I had just taken a bath. When she came close to my room I heard her footsteps and I dropped my towel. I hadn’t seen dressed this way for at least two years and couldn’t believe my pep talk had actually worked. I think bit of background history before I go any further though.My wife and I are both in our early seventies and for most of our thirteen year marriage, we’ve had the kind of sex life that most men would give their right arm for. We made love at least twice a week and weren’t afraid to experiment. We were actually swingers and I’d watched and joined in while my wife had sex with over. Not soon after that, I felt Derek spread my pussy lips apart and a strong, powerful vibration take the place of his tongue. I thought I would cum again right then and there. Derek had other plans, however. He deftly turned the vibrator off, and commanded to me, “you are not to cum this time until I give you permission. If you fail to obey, you will be punished, and trust me, you don’t want to find out what the punishment will be. Nod if you understand”. I nodded hard. I did not want to be. I followed her up to her bedroom as she dried and styled her hair.Sitting on the swivel stool facing the mirror, she let the now redundant towel fall away from her body revealing her creamy, soft flesh. There was nothing new seeing Rebecca naked, but now times were different, and I think she was well aware of it.We had agreed we weren't going out anywhere and she told me she'd had sex with our shared fuck buddy, Len, a few times during the past week and commented that he would be with us after.
