In freshers week of my first year at university, we were all drinking with the house/halls next to mine one night. One girl, who was way out of my league but I was kidding myself, was chatting to me and kept filling my cup with vodka.
After some time, she asked me if I wanted to go to her room with her for a bit. I couldn't believe it.
When we got in her room, she started kissing me, and pushing me back towards the bed. She asked me if I had licked pussy before. I told her I hadn't. She said she'd teach me.
She kept her top on but pulled off her skirt and panties and then straddled my face. It was my first time being face to face with a girl's pussy. She held my head to her c**t and told me what she wanted to do. All the while I could hear the music and laughter down below us. She used me to get her off three times before climbing off, saying "thanks!" and then getting dressed and heading back down to the party.
I felt so used, but I couldn't deny how turned on I was.
Later that night, one of her housemates drunkenly told me that she'd used me to get her nice and wet for the guy she planning on fucking later (and she did). She laughed at me called me a bitch.
Over the next week, it became clear that everyone knew what had happened. But eventually got up the courage to go up to her one day and tell her that she could use me like that again if she wanted to. She just put her hand on my shoulder and laughed, calling me pathetic. But she said ok, and told me to put my number in her phone. She texted me to come over all the time for the rest of university, sometimes before her and her friends were going out clubbing and they'd all see me come to her room and laugh. Sometimes even after she'd come back from clubbing, and one or two times after I was sure she'd been fucked by some guy.
I felt utterly humiliated for three years but I also liked it. It's still what I think about when I jerk off.
