Enough that I felt com...ortable in telling him that his wife had hit on me! Now you have to remember that back in those days we were both young and horny as hell ! I was taking my girl out parking pretty much on a regular basis naked bound and blindfolded into the woods, plus I was a kinky and devious guy always experimenting and looking for interesting sexual. Gina feverishly lifted herself up and down fucking my son's cock, both of them making moaning sounds to the erotic rhythm of their bodies."Kristy, we shouldn't..."
