"So, is it okay if I use your shower before I take off?"
At the time, this was not a completely unusual thing for me to ask of my friends. I was a law student living in a cold-water flat, so my personal hygiene options involved either showering at the gym on the way to class, or occasionally asking a favor from friends with hot water.
Then again, this was not a typical friend. B and I had been companions, study mates, and eager fuck buddies since the first semester of law school. B wasn't like other women I had dated. She was tall, with short, brown hair and a decidedly tomboyish style, favoring jeans and bulky sweaters. B had small breasts, long legs, and was an intense athlete, enjoying running and biking in the summer and skiing in the winter. All this exercise kept her trim and strong. We gravitated to one another because of a shared sense of humor, and a disdain for our classmates who took school too seriously.
During one of our first study sessions at her house, she made the first move, tossing her book aside and kissing me hard on the mouth. I grew excited as my hands started to explore her taut body, and we soon moved to the bedroom. I was immediately struck by how enthusiastic B was, tearing both of our clothes off, telling me what she wanted me to do, and cumming hard and very quickly. I was used to women needing slow and deliberate attention before they could reach orgasm, but B seemed perpetually randy and easily stimulated. Unless she paced herself, vigorous stroking of her clitoris would have her body tensing in ecstasy in less than a minute. And shortly after that, she was ready for more.
After our relationship began, B would stoke my interest by telling me about her previous sexual exploits (including an especially hot lesbian one night stand) as well as her fantasies. In the library, she would whisper to me about her most recent masturbation session or how she could make herself cum just by squeezing her nipples, while I rubbed my engorged cock beneath the desk. In turn, she would ask me to tell her about the last time I jerked off and what I had thought about or what porn I looked at while I did it. Our "study sessions" at her place quickly became pretexts for prolonged bouts of sex. In order to delay our orgasms, we would often begin by watching each other masturbate, B whispering through gritted teeth how turned on she got by seeing my hard cock. During foreplay, we would describe detailed scenarios to each other involving the two of us with another woman, or another man. Our exploits got hotter and more adventurous. She asked me to fuck her ass for the first time; I loved coming on her tits and her face; on a few occasions, she used a dildo on my asshole while she sucked my cock.
But after a year or so, my eyes started to wander. I decided I wanted to pursue some of the other women at school. B made it clear that, notwithstanding some of the fantasies of threesomes she had described to me, she had no interest in sharing and we decided to break things off. After a couple weeks, we were both seeing other people; B started hanging out with another classmate, S. But as it was a small school and we both still enjoyed each other's company, we remained friends and saw each other often.
In this spirit of camaraderie, I had loaned B some class notes. Now I was at her house having biked over to retrieve them. When I arrived, B had been doing some work on the house. She was wearing jeans and a thin t-shirt, no bra, with a little dirt on her here and there, and a sheen of sweat on her skin. She looked good.
We talked a bit and B was her usual frisky self. She handed me my notes and I was making to leave, when it occurred to me to ask about using her shower. I hadn't showered yet that day and was sweaty from my bike ride. I'd be lying if I didn't also admit to feeling a little horny with thoughts running in the back of my mind of our many hot episodes in that house.
