So I tiptoed to his bedroom door and very gently eased it open. Enough light was coming through the curtains from the street lamps outside to let me see dimly into the room. To my amazement and delight he had thrown back the single sheet that was covering his body and was hard at work on his tool. I say "hard at work" because he was so engrossed in what he was doing that he did not immediately realize that I had come into the room. His thumb and forefinger were placed delicately round his knob and he was gently rubbing the foreskin up and down with short, even strokes, so that I could only get occasional glimpses of his glans. I didn't masturbate like that, preferring to roll the foreskin down and concentrate on the sweet spot underneath the head.
Suddenly he noticed my presence and, with a start, covered his dick with his hand. "Carry on" I said huskily, "It looks wonderful." I thought I might get another lecture from him on lust, but no, either he was too far gone, or being caught red-handed had removed his inhibitions. Either way, he smiled and said "I think I will - I can't stop now" and I realized that he had been milking his dick for every last sensation and was close to orgasm. It didn't require much further stimulation. His strokes varied neither in speed nor length and very soon I noticed a small gob of white cream appear at the tip of his knob. This was then pushed out by another globule, and this in turn by a thick ooze of spunk. He didn't seem to shoot in spurts like me. "Great" I said - and meant it. His dick was like an extended triangle in shape. It was thick at the base and much slimmer at the point just under the head. Then the head itself was a magnificent mushroom. It was more than I could have expected it to be and I felt that I had achieved an ambition in seeing him jack himself off. Knowing that he would say that he was not interested in seeing me cum, I asked him if he ever did it twice. "Often" he said, simply. "Will you do it again tonight?" I asked. He considered this and then said "Not in front of you anyway." And then, after another pause, "I hope you're satisfied now."
I was - and I went to my own bed feeling very content with what I had seen and was soon doing some hard work of my own. I slept well that night!
In the morning, after my father had left early for work, I crept along to Tony's bedroom again and knocked on the door. "Come in" he called. He had pulled back one of the curtains and light from another fine day was flooding in. The sheet covered his body but I could see that he had a morning hard-on and this time he did nothing to hide it. "Having another go?" I asked. "You'd like me to, wouldn't you?" he said, looking me in the eye. Unabashed I said "Yes" - not thinking that anything would come of it and bearing in mind his feelings about "lust".
"OK" he said "Look your fill" and he folded back the sheet and there in all the glory of the morning light was the dick I had so much wanted to see. The broad knob, with the foreskin pulled back, was like a section of a slightly convex, elliptical saucer with a pronounced purple edge to it - a wonderful shape, bigger than mine and something I would have longed to have had. And his performance? Just the same as the night before, a long, long ooze, only I could see it better this time.
When he'd recovered he said "And that's it", meaning "An end to all this tomfoolery." I reckoned he'd done me a service and enjoyed two good wanks at the same time, so life couldn't have too bad for him!
He went home after we'd had another game of squash (both of us a little shagged out, I'm sorry to say) and when we met back at College in the September term we made an agreement not to repeat our "experiment" nor to talk about it to anyone. I kept to the bargain and so did he, for after he graduated I never saw him again, but I've always been puzzled by how he could categorize masturbation as "lustful", yet do it so delicately AND let me watch him.
But I'm glad he did!
