He pulled the front of his underpants down tucked the elastic under his balls and started stroking himself again, faster than before, sliding the silk...y panties up and down, rolling his hips up and rubbing his balls with his other hand. He could feel the end approaching.Maybe she would want him to jack off for her first. He had often imagined that he was a performer, going to women's parties and masturbating for them and getting paid for it. In the bathroom at home he would stand on the toilet. I can't say that Mother Superior went out of her way to involve herself in my punishments or to rule on any infractions I might have committed, but whenever she did, she was never fair to me. She always took the other side against me. She was right though, I was the oldest, and the biggest, boy at the orphanage, for a very long time. I thought a big part of the reason they kept me had to do with my being able to do so much work at the orphanage. When I looked back at it though, it must have. As is the norm when we're enjoying a day off together, we planned to indulge in a little bit of naughtiness if possible. We chose a quieter spot next to a grassy banking, however for a good while there were no suitable "targets" around so we just enjoyed the time relaxing..with DJ giving me some personal little flashes of her tits and pussy just because that's what she does! After a while a young student looking guy (maybe late 20s) appeared and took up a recently vacated space on the grass. So we would have to duplicate everyday usage. Normally, a group of men would be hard to find who would even do it, and those who wanted to would probably skew the results. So we were custom made for this study. Alone, isolated, well compensated outside the study and surrounded by women. No men other than ourselves to worry about. Also, monitored in a way which was hard to duplicate. I had to hand it to whoever thought this one up, every part of our total effort synergized with every other.
