So as you know, I recently discovered that I like my thigh spanked while I masturbate.  Well, today I had a hard cum!!  I was doggy style in this chair and was vibrating my coochie with my little toy while my man took the strap to the back of my thighs.  OMG, I loved it.  I had to tell him twice to go harder.  I think I'm in love with leather on my thigh  :)
