After a few minutes I pulled out a condom and we placed it on me. We laid down on the bed, face to face, my hardness rubbing her thigh. We kissed until I mounted her. It had been over a decade since I had been with another woman, same for her with another man. In the back of our minds we both thought how weird to be in bed having sex with a person you had only just met in real life less than 30 min ago. What a difference being with someone different. Different body, different movements, different feeling, different responses. She enjoyed herself, raising her legs each time she came. The look in her eyes was one of lust. We changed positions a few times until I finally came in her doggy style.
We spent the next 20-30 min lying on top of the covers, naked and talking. Not just about sex, but about our lives. Then I felt a stirring and decided I had to feel her without a condom and climbed on top of her and began having sex with her again. I was going in and out, feeling her skin against my skin, the feel of a different vagina and, I suppose to her, the feel of the shape of a different penis, when she asked me not to cum in her. So I stopped, put on a condom, and let her ride on top. We had sex for another 40 minutes (one good thing about condoms and getting older -- you last longer) until we finally stopped, exhausted and spent, as I unloaded into the condom while my wrapped penis was inside her.
We rested for a little bit and, after realizing we weren't up for a round 3, got up to start getting ready to return to our lives. We considered taking a shower, but one look at the shower quickly changed our minds. Instead we washed up at the sink. There we were, 2 practical strangers, standing naked in front of the sink, looking and smelling like we had sex. I stood behind her as she washed up, while my limp dick ran up and down her ass crack, fondling her breasts and kissed her one more time when she turned her head towards mine.
We washed up as best we could and left the room. After returning the key we went back to our cars, kissed. We each said we'll have to do this again. That was over 4 years ago and we haven't spoken since. I don't justify our actions that day, but it was one of the more erotic in my life.
