A very odd thing recently happened to me. I did an odd session with an online domme, or "pet owner" as she liked to be called. I played as her pet, and it was just good cybersex/domination. I told her how humiliated and turned on I'd be if she cheated on me with a bigger, tougher guy. She told me she'd fuck a guy right in front of me, and make me watch jealously. She asked me if I was bi or if I could fuck another guy. I'm no homophobe but had always thought of myself as a hundred percent straight... When she asked this question, I was frustrated. I had no desire to do it. I was grossed out, but in the end I always have to please my owner... I don't believe a good submissive should ever say no unless it's life or death.
Anyway, during our cyber session, a guy walks in. In our little game, she said she called him and told him to come. He was big and buff, and she ordered me to let him suck me. I was grossed out. All this was getting out of hand... But the minute he went down on me, his tongue felt really good. Just the fact that it made me feel good made be burn inside. I sat there, my face red, heart racing and cock swollen as he sucked me... then she told me to suck him. By now, I wanted his cock in my mouth and his precum on my face. This was so odd to me... I just wanted his dick in my mouth! IT wasn't for the dumb guy... It was for the wet girl lying on the bed watching. I was degrading and humiliating myself for her amusement, and it just felt so wrong and so right.
I sucked him enthusiastically, and then made me watch him fuck her. He gave her an orgasm through fucking alone (I've only given girls orgasms with my tongue, as I'm a sub and not too strong, etc.) She was getting fucked so hard by this guy who's strength, power and "on top" skill I could never match. She gave me dirty looks when she could, but mostly her eyes were rolled to the back of her head, as she was cumming MANY times. Finally, he finished... His sweat, her sweat, his cum, her cum.... I had to clean it with my tongue, and did so happily. Then she made me fuck her up the ass.
I fucked her till I came, and then licked THAT clean. It was over. Oddly enough, I had one last regret. I had wished he'd rammed me in the ass. I'd wanted it SOOO badly... to have to look in her eyes while getting raped by a man... and to have her taunt and tease me. What the fuck was happening to me?

Anyway, the question behind all of this. Are bisexual humiliation desires commonplace? I mean, is it common for a sub to think of himself as bi only while his mistress is watching? I honestly am not atracted to them at all, it's just that when a sadistic girl is watching me... I don't know what comes over me, lol!
