This is the same patient who tried the swing awhile back and was explaining the difference between an orgasm and cumming. I understand what he means but I'm still not clear on the difference. It doesn't really matter to me and if the guy is moaning with delight and cum shoots out of his cock then I did my job :)
He had a big dick and nice big balls to massage while I milk him. From my experience, bigger cocks take a little longer to cum and need extra attention so I made sure he had constant stimulation and I didn't miss a stroked until he released his load.
Once he started thrusting on the bench I knew I had him close and proceeded to drain him dry.
