And to stay on topic: I did BB anal this AMP girl once. Couldn't help myself, it was dark and I though I was just sliding up and down her but crack when she reached around with her hand and the sensation changed all of a sudden
She wasn't tight, asshole-wise, so there wasn't the obvious struggle to get my weinerin. Plus I was still pretty inexperienced at anal. So there I was banging away, thinking to myself, "Did she just stick me in her ASS?!"
I reached down and around and stuck 2 fingers in her pussy to make sure shedidn't park me there (she was bent over the massage table) and then before I could confirm back door penetration blew my load. Too bad the lights weren't on. Must've missed one helluva anal creampie scene!
Anyway, about 2 seconds after you cum you end up freaking out and kicking yourself forever (or until the testresults come back, whichever is first). So it's best just to avoid this kind of craziness altogether.
