I had a girl friend a few years ago who used to lie on her back on the edge of the bed, then I would stand up and my cock was just perfect level to slip into her willing anus, then while I fucked her ass hole she had her legs in the air so I could suck on her toes. She was great. Anus fucking and toe sucking mmmmmmm
Then I would lift her ass up and get my tongue right down her shitter. After having had my cock in there for a while her ass hole was quite wide open and it was great to put my tongue in deep and feel her sphincter close up on my tongue.
