I also have a fetish for gangbangs too, first exp was in BKK 2 yrs back, 2 guys + 2 gals, feels really high doing it.
But I have a fetish to be in gangbangs with the other guy having a large dick fucking the gal. Feels really high for me when i see that. Found out about this when brought one ang-moh friend to ktv, both of us got sucked off on same couch.
Until we normally go hunt together. Last month we did a 2 guys + 1 PRC gal, got me high when she held both our dicks to her mouth, taking turns to suck our cocks. Especially when she can suck my whole length but can only take half his shaft. Sick and strange fetish I have.
Unfortunately she did not allow me to take pics, otherwise it would have been posted in the Private pics section already...
