When I was younger, maybe 19 or so, I caught my girlfriend cheating. She and I were over at one of her sisters friends apartments. You know the kind where the laundry facilities are in another building. Well, we are there watching a movie and I'm doing some laundry. I got up to go change the clothes to the dryer and when I left and passed by the window I could see in the room. the TV was still going but only now he was over standing in front of her with his dick out and she was blowing him. I watched for a bit then I watched him tense up and he came in her mouth. I was so pissed cuz she always told me to not cum in her mouth....that she didn't like that.

Later that night I finished up my clothes and packed my car to go home but couldn't resist getting some payback. I asked her to suck me off before I had to go. She was going at it when I said I was close. She once again said don't cum in my mouth. When I felt the urge I grabbed her head and came in her mouth then pulled out for the last couple spurts that hit her face.

I asked if that's what his cum tasted like. She knew she was caught and said yes. I asked if she sucked other cocks and she nodded. I asked if she fucked anyone else and she said yes again. I told her I had to go but I would call her to discuss this when I got home. I never talked to her again after that night.
