Lots of oral sex, nude holding and mutual masturbation before I ever had intercourse with someone, but I'm guessing that's what this thread's about, so about my first time (which both of us definitely enjoyed)...
I met "Liana" where I worked: she was tall, blonde (natural blonde, as I later found out), statuesque, lovely, about 10 years older than me, and (as far as I knew) very married. She had asked for my help on several occasions, and of course, I was happy to oblige. But one morning, she met me at the door and said, "I'm running out of excuses to come talk to you."
We sat down outside, and Liana asked me if I would like to have lunch with her. I said, "Sure! What's the occasion?". She smiled and said, "I would really like to get to know you better."
I was with someone at the time, though, so I told her that. She smiled sadly and said, "I should have guessed. We'd probably better not, then."
As you can imagine, my head was spinning. I told her that if I didn't have a commitment to someone else, I would have said yes in an instant. Liana smiled again and said, "Thank you for telling me that. But I'd better keep my distance. I'm very attracted to you, and it's not Platonic. I want to have sex with you, and leave my marriage."
Liana wished me the best, but asked me to call her if I ever changed my mind.
Six months later, my girlfriend and I had broken up. My guess was that Liana had long since moved on, but when I said that to a female friend, she laughed and said, "You don't know very much about women, if you think that. You should call her."
So I did.
Liana had NOT moved on, and was very happy to hear from me. We met a few times for lunch. She talked about how her husband had gotten more and more abusive, and she really wanted to leave him for someone like me. We would hold each other and kiss, but I told her that was my limit unless she separated from her husband.
But I looked forward more and more to seeing her each time... it was hard to think about anything except her.
One afternoon, she asked me if she could come up to my dorm room, so we could kiss there. Of course, I said yes... but once we were there with the door closed and locked, and after a few minutes of heavy kissing, she said, "I want to take my clothes off now."
She stood up and did exactly that, stripping to her panties. (Could you have stopped her?) She was even more beautiful than I'd imagined... and I'd imagined a lot.
Liana told me I didn't have to undress, but she wanted me to touch and hold her that way.
The rest was history. Details to follow.
