Oldawg, you rule!
This is one of my favorite things to watch in porn, a guy licking out a tgirl's sweet asshole. I always fantasize it's me in his place.
Loved the story, too, and I don't blame you for "getting carried away." A tgirl's ass is a special thing, and so close to her beautiful cock and balls that you can lick her all over down there without traveling too far!
