A night of sexual exploitation with a depraved roommate

After a long day of classes, I came back to my dorm room to find my roommate in the throes of ecstasy, his pants around his ankles. I couldn't help but be drawn in by the sight of his tight ass being vigorously pounded. The sight was enough to get me hard, and I found myself joining in, my cock sliding into her tight hole. As I fucked her hard, she moaned and writhed, her body quivering with pleasure. I could feel her tight asshole clenching around my finger as I pushed it deeper inside her. The sight of her being stretched wide open by my thick cock and finger was enough to push me over the edge, and I pulled out to release my load all over her ass. The sight of my cum dripping down her tight ass was enough to make me want to fuck her again, but I knew that I had to stop before I exhausted myself.
