I fantasize about my girlfriend having sex with my friend
Way before I had a girlfriend, my closest friend and I used to goon together, to the point that we started watching porn and jerking off together. The first time we did jerk off together something change on me forever. I saw him naked for the first time and saw his really big dick that you see on those porn videos. His dick really made me feel something I have never felt before. After that first time, most of the times when we jerked off together I just stare at him stroking his dick and he wouldn’t notice because he always closed his eyes. My friend is the type of guy to not talk to girls and have really bad luck with them, so watching porn and jerking off together with him was his way to be satisfied and it was mine at that time. Then I started having a girlfriend, and those moments with my friend stopped. My friend did feel very lonely and I felt bad for it. So one day after months, we decided we were going to jerk off together again so I went to his place. The moment I saw him naked, I started fantasizing right there of him fucking my girlfriend. It felt so wrong, it felt so taboo, I was confused “why is that thought turning me on so much”. I was so turned on by the thought of it that I showed my friend nudes of my gf and he started jerking off to them. While my friend was stroking his dick I told him “I want you to fuck her” and I was in shock I said that and a little after he came. Now every time we jerk off together, is about my gf and he tells me what he wants to do her and stuff and now it became something that I want to actually happen.
