When I went to uni I was a virgin and had never even kissed a girl. I hadn't got the grades I required to get the places I wanted so I went through clearing, this all worked out well but it meant I ended up in a private house share. Three of us were sharing, myself and 2 girls, Claire who was a goth and kept herself to herself and Sarah who was always rushing around and seemed angry most of the time. For me it was a place to crash and get on with my course.

One night I came back about 2am and Sarah was crying, I offered a hug and a drink and she accepted, we ended up chatting for a few hours and innocently fell asleep on her bed. She was a bit nicer after that.

A few weeks later I was having a shower and she knocked on the door begging to use the toilet, since I didn't think she would see anything I said yes. When I heard her strong stream of piss I couldn't help but peek round the curtain, she saw and called me a fucking perv, shouting that I would probably like to drink her piss and eat her. I didn't reply and she left. Later we bumped into each other and she asked if I liked seeing her piss, I went bright red and said I couldn't see anything, even this made me hard which she saw, she reached down and grabbed me, saying I clearly did like it, he closeness and touch made me cum in my pants. I was so ashamed. Pushed her hand away gently and ran to my room crying. She left me a few minutes and then followed, giving me a hug and apologising. We then discussed my lack of experience. She then admitted she thought I was hot and was hoping we could be fuck buddies - at this point I thought all my dreams had come true, she finished the sentence saying that she didn't have time to teach a virgin that cums in his pants and I clearly didn't have the experience to pleasure her. She wasn't quite that blunt but that was the sentiment.

I did my best to avoid her, over the next few weeks she found her fuck buddy, I spent lots of nights, masturbating to the sound of them going at it like rabbits.

Towards the end of the second term I overheard her having a massive row with her fbuddy and doors slamming, I could hear her crying so I went to see if she was OK, I didn't consider I was only wearing my boxers. She sobbed into my shoulder saying he was a cheat etc etc, we again chatted into the night and fell asleep. In the morning I woke up first she was slightly out of the covers and the top of her bra was on show, this made me stare and I was instantly hard, she then stirred and caught be gawking, sleepily asking if I was enjoying the view, I went red, she sat up letting the covers fall, reached behind and unclasped her bra, letting it fall away from her breasts. They weren't great if I am honest but for a horny 18yo virgin that didn't matter, I couldn't take my eyes off them. I remember her bursting out laughing at me, saying they were just tits and she couldn't believe how pathetic men were. To my surprise she then straddled me trapping my hard cock against her crotch (we both had underwear on) and began grinding into me, I went to put my hands on her breasts but she pinned me down saying she needed my dick hard, she eventually came and I managed not to. She then rolled off me telling me I could wank over her breasts if I wanted, I was too scared to.

This was the start of a pattern, we would chat into the evening, she would grind on me until she came and we would fall asleep. Neither of us really drank but one night she came home with some wine saying she had a shitty day. She finished the bottle and went to grind on me, this time she removed her panties and said she had always wanted to use my face and straddled me, I did my best to lick her, I think my in experience frustrated her because she told me to keep still and ground into it, once she had cum she told me I could lick her clean if I wanted (of course I did).

Over the remaining months she continued to use me which I loved, some times I came in my boxers but she never touched my cock again.

As we were both moving out she gave me a big hug and thanked me for being there for her, we have never spoken since.
