There she lay, my gender bender whore, and constricted her balls just like I advised her to. She hat to fuck herself with a medium sized plug to warm up.. but I did not like this position. For the upcoming backside jerk off I attached the constricted cock and the balls to the bitches manacles doggy style. She was totally defenceless with the strap going from crack up to her back. I did her hardly and lustfully while she moaned loudly until her juice squirted on my gloves. I licked the juice with pleasure.. a very special jerk-off.
