he cheated on me but i still got what i wanted

so my fiance is this hot young prof at the uni where i work and we were engaged like 6 months ago. he's been keeping secrets from day one which really made me suspicious, turns out for a while there was some other chick that he was hooking up with on the side but not anymore. i figured i would be over it after a week or two but as soon as we had our fight about it i just felt this burning rage and desire to fuck him hard in his office right then. so i did. i told him to strip down right there, he was all like wtf what are you doing, but when i got my hand on his cock that shut him up real quick. i got on top of him bent over the desk and started riding him rough, no lube just dry sex with me taking it hard in my pussy. i couldn't get enough so i kept slamming down harder and faster till we were both sweating like crazy from all the friction and moaning. i rode his dick until he came balls deep inside me. i wanted to feel him cum and stretch me out, have that hot seed filling me up from the best orgasm of my life. then once i was done riding him raw we just laid there on the floor for a while catching our breath. it felt so good, i'm still feeling that buzz now even after all these weeks.
