[Amateur Submission] I really want to see my girlfriend being NTR'd... I had sex with her using a friend, and I'm sharing videos of my erection NPJS-144

I've had a fetish for NTR (Netorare, a Japanese term for infidelity) since I was a student. It started when a girl I liked dated a friend, and I heard his vivid stories about it. Now, the more I like my girlfriend, the more I want to know what a woman's face would look like if she had sex with him. Just imagining her moaning and groaning makes me want to ejaculate. I've reached my limit... She's such a wonderful woman. If we could have sex, my friends would be scrambling to get her. I'm sorry, I'm the worst boyfriend. But I love you.
