I went for my fifth acoustic shockwave session today. I abstained from jerking off for five days beforehand. Before I left home, I took four 5mg tadalafil (Cialis) and four nitric oxide capsules. By the time I got to the therapist's, I'd been stroking myself through my pants and was getting close to erect. After I stripped and laid on the table, I played with my cock and skinned the bit of foreskin I have left right back so my glans was completely exposed. When she came into the treatment room, we chatted while she put on her gloves, and then she squirted on the conductive gel and seemed to be taking longer than usual to spread it above my cock, onto the shaft, all over my scrotum and down the length of my perineum right to my ass. I've generally found myself chubbing up over the course of the treatment, but this time, I was throbbing by the time she'd finished the groin area above my cock. When she held my cock to treat the shaft, I was completely hard and pulsating in her hand. I'm not sitting upright enough to see everything, but I could tell that she was watching very intently as the treatment progressed, and my cock was so hard that I was constantly throbbing and I could feel it jumping and becoming airborne as she worked at it. By the time she finished at the end of my perineum, I could feel my cock clenched and remaining clenched away from my body. I was beginning to wonder if there was a chance I might cum before it was over. When it finally stopped, she gave me a warm wet towel and a dry towel to clean myself up, placing them both directly over my cock. I got the distinct feeling that she pressed the towels down so her hand was pushed up against my hard cock. After she left to let me get cleaned up and dressed, I noticed that there were long drools of precum webbed between my glans and my belly, and I'm sure she had to have seen them. I was so horny that I desperately wanted to jerk off before I got dressed, but felt obliged to wipe myself and dress quickly in case she had another client waiting for the room. I made sure that when I dressed, my cock was still completely stiff and jammed into the opposite side of my jeans from where it would normally be so I could exit the room with a nice big bulge to show her when we set up the time for my last appointment. I've been thinking about this since I got home, and hope I can manage to cream in front of her when I'm there next time.
