In this phone sex business you do indeed lean something every day. For years a caller told me he masturbated without using his hands and I couldn’t quite picture it then one day I watched him on cam and got quite an eye full. I had never visualized this, legs spread and shaking back and for like some sort of odd dance of self love. I guess variety is indeed the spice of life and no harm done. He shimmed and he shaked and then a load of cum went flying. Not one hand touched his cock or balls the entire time.
I’d think this method might be a bit hard on the back and could easily put it out, but if it doesn’t harm you, go for it. Another caller would get on his back and cross his legs at the knees up in the air and looked like he was doing stomach crunches. He was fully clothed, he literally could have done this in a public gym and not one person would have been the wiser as to his actions. There was no indication he was doing something sexual other than his yells of ecstasy!
Another caller is a pillow humper and he too is not using his hands, he’s on his tummy fucking a folded over pillow. The variety of techniques people employ in the name of self gratification is impressive. Women can as well, from pillow humping, to thigh pressure with the legs crossed. One doesn’t always need to use their hands to give themselves a good orgasm. Creativity is always a good thing. The swinging the cock and balls back and forth between the legs is a new one on me though, I had not heard of this or seen this until now.
