I was browsing around looking at porn and craigslist. An add that said “Looking for a Submissive Bi-Sexual Slave to Serve us both” caught my attention. The add said that they were looking for an obedient young guy to perform oral on both of them while they had sex, and then clean up afterwards. I imagined putting myself in that situation and I started to fantasize about joining a couple for a threesome.
I decided to post my own add. I described that I was looking for an open bi-sexual couple that would be interested in having a threesome. I went on to elaborate that my fetish was to play the submissive role for them, that I wanted to suck his cock and let him fuck my asshole. I wanted to be subservient and there to enhance their pleasure. I thoughts of role-reversal, being humiliated and dominated turned me on so much.
