I Still Remember The First Time I Was Ever Cucked. My Gf And I Were Staying Together In A 2 Bedroom Apartment

I still remember the first time I was ever cucked. My gf and I were staying together in a 2 bedroom apartment and we both worked. One night I came home to hear moaning and our bed squeaking. I quietly walked upstairs to our bedroom door. It was open slightly so I could see inside. And there was my petit 4'11" gf getting pounded by a another man. They couldn't see me to I just watched. She was lying in the bed on her back with her legs in the air, and he was standing next to the bed fucking her. I watched her as she moaned and cried out for more. I watched her B cup tits bounce each time he trusted inside of her. I looked at him and saw his cock was about 7 inches and he wasn't wearing a condom. I took out my (much smaller) penis and started to masturbate. About 5 or 6 minutes later he came inside of her and I had fun all over myself. I quickly ran to our spare bedroom to hide and clean up. I listed as they made out for a few minutes before he put his clothes on and left. I ate her out that night and swallowed his cum from inside her 😁 thank you for reading
