I really get off when my wife takes control. I love it when she grabs my balls and squeezes them 'til I can't stand it any more. Sometimes she'll do it when she's on top or when I'm masterbating. She says she likes to think of all the guys that pissed her off that day and shows me what she'd like to do to them, so, while she's talking she'll grab them and stretch them....and without warning...slap- and I'll feel a sudden twing of pain in my lower stomach. Then I cum like there's no tomorrow. Other times, she threatens me with pain if I don't cum on time! She'll count to ten and, if I havn't cum yet, wham - I feel the full force of her slap right on my twins.
She even bought me a scrotum stretcher/spreader so she can see them better and she can't miss 'em when she smacks them.
I don't know if it's the pain or the helpless fealing I have when she has my scrotum in her hands or, seeing the pleasure in her eyes when she takes out her daily frustrations.. But whatever it is, it really turns me on. Am I really that strange or are there other couples out there that like the same kind of S&M sex.
