Naked Gym : Milfs Unprotected 19

Sometimes our basement gym can get kind of hot, so what better way to work-out than by stripping-off completely?  I didn't know Mike was staying over, so when he comes down the stairs for a gym-session I have nowhere to hide!  I don my clothes and we work out together, but the more we continue the more we both want to strip off.  Read as the pair of us gets sweaty together, doing things a woman should never do with her son's friend.
