I was in college. I lived at a house with about 10 other guys. My living area had 3 roommates. One of the guys was a friend of mine from high school. He was a year older. He was tall, athletic, and had a reputation with the ladies. He was a basketball player and had basketball hands.
One night we had a party at the house to raise money. I invited my girlfriend (now wife) to hang out. Party was big, everyone got hammered. I remember walking upstairs to my room (which was a loft) and seeing my friend talking to my girlfriend near the foyer we had. They were very close and face to face. I was going to say something, but chose to watch.
He said something to her and she cracked up then he fell on her over into futon. Her legs were spread and he just dry humped her right into it. She pretty much embraced him. They laid there for a second and didn’t move. At this point, I bugged out and screamed some nonsense and stormed down the stairs.
To this day, I still regret seeing if she would’ve cheated on me there. She ran after me, obviously, but, I wonder what she would’ve done if I didn’t fuck it up. I’m pretty sure she would’ve fucked him, but who knows
