When I was a student at the U, I had a Chinese gf. She liked dancing a lot. Once, there was a salsa workshop in our building. We went there, but it turned out the tutors were 2 black guys from Cameroon and there were 2 more couples practising with them. We tried to mimic their moves. But soon one of the black tutors stopped me and told me to watch. He took the lead with my gf and she soon adapted to his moves. I never liked salsa, but wanted to give it a go. However, the tutor told me to keep watching and I sat down by the wall. He went into precise instructions of how to tilt and shake the body while placing the feet in this and that position... So I got bored and told my gf I would go fetch a beer. She was busy paying attention to the tutor.
I did fetch a beer but went into my room to watch football.
After perhaps 40 min, she came to my room asking why I left and said she was sweating a lot from all the dancing exercise. She took out her clothes and went directly into my shower. I picked up her clothes. Her pants were lightly moist. But there was no bra. As conservative as she was, she would rarely leave the room without a bra.
Next week, I came from class to the communal kitchen, asked for her, and her friend said she probably was at the salsa workshop. When I went to the bar where they practiced last time, the door was locked. I could hear the music playing though, but no one in there. One of the barkeepers came with a crate of beer and told me to check in either room of the tutors nos. so and so. Went to the one of their rooms and just there I could listen they were playing loud African music inside. But most notably I could hear her laughing. My heart and throat froze. My head was about to explode. Then one girl came behind me through the corridor and I moved away to the staircase. I was filled with fury. I told to myself to calm down, wait, and pass by another time a little later. But what would I do then? I looked at my watch and gave myself some time. I was boiling after some minutes. Went to another kitchen, drank some cold water. I decided to go past the other tutor's room. He had left a message: "I'm in the bar". I quickly went back to the corridor of the first guy. The music was still loud but anyone could notice there was some hot action on his bed. I couldn't help to put my ear on the door and could hear a little of their moaning.
I went to my room and cried like a stupid. That was the last time I ever felt weak. I would not ask her. I would play along. And I would make a whore out of her. That night I noticed they have stretched her pussy nicely. I told her we would need to open the back door from now on. She was horrified, but in the coming nights I opened her butt hole for the first time. For that night and some others later, I fucked her throat, let her lick her boobs, facialised her, and showed her a lot of lesbian porn. Then, after a month or so, she had her face covered with rash: we both got chlamydia. I healed and soon dropped her for another girl.
She was used to lies and I was always a bit suspicious. But I was fond of her for a while. I left out, however, that the evening of her cheating I had a permanent hard on. Thinking about that contradictory experience I lately realised that I didn't look for revenge when I decided to use her, but I was celebrating her naughtiness. When I met my gf / neighbour months ago it was like going through similar stages of that exp. The difference now is that I'm bringing all of this to another dimension and am per agreement sorta pussy-free.
