Hi everybody. This was originally posted in another subreddit and I was told to post it here! Hope you like it (it's a completely true story, btw). In case you're curious, we're in our mid-20s and she is a petite little knockout. A couple nights ago me and my girlfriend started getting frisky in our bathroom after a relaxing soak in the tub together. I laid on the floor and she sat on my cock and rode me while I fondled and smacked her sweet little ass. After a while she asked me to fuck her doggy-style, so I turned her over, got her on all fours and fucked her hard. "Cum for me baby," I said, and after five solid minutes of me taking her from behind she did. Then we moved to the bedroom, slipped under the covers (it was cold as hell) and I started kissing her. She said I could have her however I wanted and could do whatever I wanted to her. I got on top of her, slid my cock into her warm, wet pussy and started giving her slow, deep strokes. After a few minutes I told her what I wanted: a description of one of her one night stands from about six years ago. My girlfriend has a bit more of a sexual past from before the relationship than I do, and it includes a couple of one night stands. When she first told me about them early in the relationship they made me really jealous (they still do). Over the years, however, I've had some fantasies about her fucking other men. So, about a week before this story I'm telling here, I asked her if some time she could describe her one night stands while we're turning each other on/having sex. I was a bit surprised (and really happy) that she immediately got into the idea. Anyway, I was on top of her, fucking her slowly when I whispered in her ear: "I want a little story about your slutty past." She started me off with a teaser: a story about how she got drunk with her roommates one night (about six years ago) and was feeling horny so she borrowed a short skirt from her hottest/sluttiest roommate and went to the bar. She described the short, slutty little "fuckskirt," how it showed off her sexy legs and how she went and danced with some male friends of her, turned them on, rubbed her little ass against their hard cocks, teased them and then went home without sleeping with anyone. Then she told me about her first one night stand: how they made out in the back alley behind the bar, how strangers saw them and told them to get a fucking room. She told me how they went back to his shitty dorm room (they were in college), how he removed her panties and put lube inside of her. She was basically moaning the story by this point.She told me about how she sat on all fours on his bed and slowly backed herself up onto his cock. How he took her from behind, fucking her hard, teasing her nipples, rubbing her clit. How she got on top of him and rode him, just like she was riding me at that point in the story. How good it felt, how wet he made her, how he came inside of her. When the story was over I whispered in her ear, "moan his name" and she did several times. That set me over the edge and I came hard inside of her, filling her with my cum. It was some of the best sex we've ever had.
