I have been having laser treatments to remove the hair from my back and from dick and balls for about 18 months. I have a lot of body hair. The tech had never done a guys dick before but she was fine with it. The laser being used requires skin contact by the laser. It is also much better if she applies a little pressure. This is fine when working on my back but on my dick and especially my balls its hard to apply pressure.
I finally talked her into trying the treatment when my dick was hard so she could apply pressure. She would apply an aloe cooling gel and actually rub my dick a bit to get me hard. This led to jokes about having to take care of myself after the treatment. She would jokingly say she was going to leave me alone now. Well the last time, I mentioned that I missed having her put the second 'healing balm' on after I was done and asked if she could stay until after I took care of myself and apply the balm.
She actually squirted some gel into my hand and stood back while I jerked off and came into a small hand towel. She reached out for the towel and then took hold of my still hard dick and rubbed the balm into my dick and balls. All she said was 'wow' when I came and not a mention was made of the incident.
