I find a rabbit punch to the nut sack all ways cheers me up. Fun AND empowering. I also love it when I grab a handful of scrotum, making sure the balls are below my grip and pull upwards until they are standing on tiptoes and I've got 4 clothes pegs clipped to their foreskins. I really get off on the way I feel their balls spasm and try desperately try to suck themselves past my fist and up into their bodies. The begging is always reaches that pitch of desperation. That shit just gets me moist!
