Recently, I was at a leather fetish/sex party. There was this cute bearded guy working as the bootblack in the front room. At the end of the night, as the party was winding down, he approaches me in one of the back rooms, and says "Would you fuck me with that thing?" I say sure. While I'm lubing up my cock and getting it good and hard, he slips off his pants, and lies down on his back on this buck, but with his legs together and feet still on the floor.
I'm ready, so I lift up his legs, and... That's when I found out that "he" was actually an F to M transexual, and despite the nice beard, all was still original equipment below the waist. I said "Just give me a moment," and then shoved my cock in.
I actually have to say it was quite nice, and regret that the experience came so late in the party when I and my cock were rather tired out. Then I got in deep, and felt my cockhead get tucked up by the cervix, and... OH MY GOD, nobody's ass ever did that to me! These straight people just might be on to something....
