It just seems he´s getting his ass ready for a good licking. Some tumblr blogs are pure fantasy, though it´d be cool to see it happen someday
Judging by the size of the hand that holding his dick, I'm pretty sure that's a lady, and as Aaggii said he's probably going to get licked by her. The fact that the person was cropped out of the picture makes me certain that definitely a lady on the other end.
"smiling gives u wrinkles, bitch face keeps u pretty"
