I came to uni with my boyfriend and now I'm wondering if that was a smart thing to do.

I'm a fairly pretty asian girl at a big london uni and have quite a lot of hot guys hit on me, especially at parties.
Which is exactly what happened last weekend.

My boyfriend wasn't there, so I got talking with a guy I found seriously hot. Eventually alcohol made me really flirty with him and he suggested going to somewhere a bit quieter. We found a closet and we just started kissing right away.
I was so turned on. This guy knew I had a boyfriend, and so we both knew I was cheating on him. It turned me on a lot. His hands moved down into my panties and he began to finger me as we kissed. Eventually, he made me cum, hard.

He then unzipped and made me get on my knees. I had never given my boyfriend a blowjob before (I only give him handjobs, although he does lick my pussy for me) so I felt especially slutty as I took him in my mouth and focused on pleasuring him as well as I could. I heard him take a photo with his phone. He promised not to show it to anyone which I didn't believe for a second but tbh I didn't care much by this point. My boyfriend is quite submissive and I was enjoying cheating on him.

I could tell he was about to cum and I wanted to swallow it all so I gulped down each spurt as it came out into my mouth. Once we were finished he zipped up, kissed my forehead, and we both went back to the party.

I felt a little bad later on when I kissed my boyfriend with my cheating lips, but it was made a bit better by him licking me before we fell asleep. I felt especially bad for reminding him that I was sorry but I wouldn't suck his cock, as I "didn't feel ready", and he said he understood. What a beta male. I just licked his nipples and stroked his cock until he spurted for me, no idea what his girlfriend had done earlier that night.
