I love my wife to restrain me and make me cum without any penile stimulation by using two vibrators, one that hits my prostate from inside and one that vibrates it from outside.
My wife first restrains me into a position making me utterly vulnerable to frontal anal penetration and completely helpless to stop it. She tapes my wrists behind my back and lays me down on the bed, naked of course. She has me push up so she can slip a foam roller under the small of my back just below my taped wrists. Then she tightly pulls my legs wide apart and back over my head with this fun little restraint:
Next she snaps a leather strap with a chain leash tightly around my cock and balls. She pulls the chain tight and snap hooks it to a metal ring in the front of my leather collar.
My hairless taint and anus are now upwardly oriented, and both are stretched as tight as a drum. My wife lubes my anus and opens it up with one, two, then three fingers. She lubes and easily inserts the prostate stimulator with only a few gentle pushes. It deliciously fills my rectum. I feel its bulbous ribbed section massaging my prostate perfectly as she pops it into place. I start clenching down on it to enjoy it more. Then she turns on its vibrator. Wow! If she touches my cock at this point I cum almost instantly, but she won't touch my cock at all, and she will still make me cum.
My wife runs her hand up and down the entire eight inches of my tightly stretched out taint. She says she can feel the vibrator inside me, and she uses a felt tip marker to mark the exact spot. She pushes down on the spot and rubs it and massages it. I can cum from this alone, but she takes her hand off my taint. She grabs our Hitachi Magic Wand vibrator, (without any attachment), and moves its round head slowly up and down my taint as it vibrates on the low setting. Then she puts the head of the Magic Wand on the spot she marked. The sensation of two vibrators squeezing my prostate from two sides is amazing. I moan with pleasure as she just hold the wand on that spot for several minutes. She switches it to high and gradually starts to increase the pressure of the wand head on that same spot. The pleasure is insane and grows more intense for several more minutes until I finally cum.
It's such a powerful orgasm because she never touches my cock. It's all anal. My orgasm wells up very powerfully yet slowly from a place very low down, far from my penis. It builds for several minutes. The pleasure gets stronger and stronger until it feels like an orgasm, even better than an orgasm, but I still don't cum. The insane pleasure goes on and on. Finally I feel the orgasm starting, but it seems like it still takes more minutes to finally come. I explode and my whole body begins convulsing in ecstasy. The pleasure exceeds everything but the very best sex we've had together.
My wife loves to watch me cum this way. The restraints position the head of my cock high over the center of my chest, so that several big squirts of semen always hit me in my face and chest. She squeals with excitement when I cum all over myself. This time a big blob of cum lands in my open, gasping mouth. "Now you know what it tastes like! ", she laughs with delight.
