That's funny. He really seems to get into playing with her hair and having fun with it at times, but it is not a sexual turn on for him.
I also love the way her face lights up when she's playing with her hair. I've noticed that with some of the other girls, too. Its probably a nice break from all the cock sucking they normally do.
Anyway, thanks again for shairing the wealth and keep up the good work.
PS -- If you ever find a couple willing to do it, I would love to see the girl tie her man to the bed and tease him with her hair.
