This happened when I was about 23 years old. My English isn't that good as I am Dutch.
When I was about 23 years old and was out in a bar with some friends in the Netherlands, a girl I was talking to was telling me about her boyfriend. From what I heard there was something wrong with her relationship, and I told her. She started crying and I provided a shoulder for her.
When I met her again, she told me they had broken up. She was obviously trying to make me into a rebound, and that was fine by me.
Pretty soon we were hooked up, and after having visited a friend of her, we went to the alley behind her friends house to make out.
This is where this happened.
Pretty soon we were kissing and touching, feeling each other all over.
I moved my leg in between hers, and grabbed her butt with both hands.
Our tongues were twirling, and things were heating up, and I pulled her into my leg with a little more force, pressing her pussy up against my leg.
This obviously got a reaction from her, and things heated up more. I started a bit of a rhythm going, and she got flustered and started rocking herself.
I anticipated her movements, and she stopped kissing me and started moaning in my ear, much to my pleasure.
Eventually her eyes were closed, she was breathing and moaning constantly, and suddenly her movements became inconsistent as the orgasm washed over her and she almost lost control of her legs.
She looked at me a bit sheepishly after that, and felt a bit embarrassed about what just happened.
I comforted her and told her that it was ok, and that I was glad she enjoyed it. Unfortunately there was no time to return the favour, and soon after that we broke up. I still look back at that moment every now and then just because it was so much fun to do, and the fact that I was able to bring her to an orgasm with both of us fully clothed still makes me smile.
Hope you enjoyed this short story, it was my first one after having read so many nice stories from all you guys!
