I caught my dads friend jerking off

I stay around at my dads on Saturdays and he lives with a roommate (his friend) he sleeps on the couch as the house is already full. And i sleep in with my sibling. (My sibling wasn’t there this time btw)

So i went downstairs to get a drink, it was really late so tbh i didn’t expect anyone to be up. But anyway he didn’t have a blanket or anything like that covering him but he did still have his sweatpants on, although they were half off so i could see his big cock. I wanted to look away but I’ve never been so horny in my life. He was letting out little noises that I’ll remember for the rest of my life. The fact that he was even risking being seen by someone made it so much hotter. He was lifting his hips basically fucking his hand like he was craving a pussy instead. I wonder what he was jerking off too. I watched him cum all over his stomach and i swear it gave me butterflies.

I went back to my room and i humped my pillow because i couldn’t sleep after that. The next day i swear he was looking at me differently like he knew i saw him.
