yrs ago there was one on Blanco. I was in doggy with here and suddenly she looked back and said
You want to fuck my ass........ I said yes
Dont know of any now but would like to find one....
Closest I've ever came was at QQ one time when I put my thumb in the girls ass while in doggy... she liked it and it was so hot that it put both of us over the edge.... YMMV on this one though..
