Best things to do while between sets are looking at girls boobs and talking a good whiff of a ovulating woman. And since it is so hard to find picture of girls on the internet I would be happy do sell you some (picture of your wife or girlfriend cost extra). I can also sell you that sent of an ovulating woman in a new product I have trademarked A.I.R. PM me for a full price list.
