There are several massage therapy schools in our area. I've taken advantage of their 50 minute massages for several months now. The students are professional and adept at relaxation massages.
I've been requesting the same young man for the past six weeks. He's getting to know what I like and what I don't like. The school rules insist that draping is always used and none of the therapists have even touched my buttocks although today's session was quite exciting. I'd asked the therapist to concentrate on my legs and hips. While laying on my stomach, my upper legs and hips got ample attention with plenty of lotion being applied along the outer portions of the upper legs and hip areas. The therapist then rocked me from side to side by pushing against the hip area. Well, that got me aroused to the point of pre-cum and just beginning to get hard.
While laying on my stomach this was not a probelm. I didn't leave any stains on the sheets.
When the therapist announced that the session was over, he told me to take my time getting up and dressed. And, I did. I took the opportunity to grab my penis and in about 45 to 60 seconds had worked myself into a very enjoyable orgasm.
