Is it normal to seduce a fellow student while in class?

While helping my dad pack for his move to Dallas, I found some of his old workout shirts. He called them "muscle shirts", and they were basically sleeveless t-shirts with huge openings for arm holes. I asked if I could have them (they were xl so much too big for me). I wore one of them to class at the university this past Monday. It was tie-dyed and swallowed me, but my tits were free to bounce and if I leaned forward even a little, my tits were in full view from the arm holes. I wore a really short jean skirt with no panties and my favorite butt plug. When I got to class, I sat next to a really cute guy and made sure he got plenty of good looks at my tits. I caught him looking and winked at him and asked if he liked what he saw. When my professor turned his back, I pulled the opening aside where my classmate could see my entire tit. As class ended and I was getting up from my seat, I made sure to let him see my smooth pussy. After going up to my instructor to ask a phony question (I just wanted to let him get a good look at my tits, the poor guy was so nervous he could barely talk), I went back to talk to my classmate. The room was not going to be in use for the next hour or so, so I asked him if he would like to fuck me. He did! Is it normal to seduce a classmate during class?
