So I had* a girlfriend. I am also bisexual, and only my girlfriend knows that. So once me, her, and my best friend get so drunk that she tells him. He doesn't say anything, and just leaves. The next day he comes over, and he tells me he will make his cock an "all I can eat whenever I want" if I let him have sex with my girlfriend. So he lets me call her, but she's at work. He lets me suck his dick till she comes. When she does come, I tell her what's up, and she seemed more than happy. He fucks her infront of me, and even allows me to join (the catch is, I am only to touch him, not her) so I suck his cock while he makes out with her, and he even slips his cock in my ass for a short while, but doesn't let me fuck him. He finishes sex with my gf, they are both naked, and they both thank me. Then day by day, each time we met up or saw each other, he would let me suck his cock, and I would love it. I sucked his cock at the bathroom mall, in my parents' bedroom, and even at a party, when everyone was asleep. I got addicted to his cock, and once when I was sucking him, he started asking for my gf to go with him alone. I began to object, and he pulled his dick out of my mouth and told me to get lost then. I apologized to him immediately and kept saying sorry, and lusciously and lustly tried to grab his dick and suck it. He asked again, and I said sure. That time was the best cocksucking I ever gave, cuz it was almost taken away from me. He started letting me suck his cock only infront of my girlfriend, and I would feel humiliated but I'd love it. Me and my girlfriend would take turns sucking his cock sometimes. Eventually, after about 5 months or so, my girlfriend broke up with me, said I'm not a man, and she started going out with my best friend. We don't talk a lot like before, but lately we started hanging out. We hang out now and then, and I suck his cock from time to time, because I honestly love it.
