He's embarrassingly small.

[WARNING: Choosing this path will inevitably lead down a path of small-penis humiliation, femdom, and maybe feminization.]

Joshua knew he was smaller than average. Much smaller. He blushed in embarrassment that the woman of the salon had noticed how small he was, even through his underwear.

As often happened, his humiliation gave him an erection. He didn't know why this happened, but he couldn't help it, as much as he hated sexual humiliation, his penis felt differently. It grew to it's full size of just a few inches--barely enough to tent the front of his briefs.

The women seemed to pretend not to notice, for his benefit, but the giggling and chatter in Korean increased ten-fold. One of the women brushed over it with the back of her hand, causing it to twitch in desire. She pretended it had been an accident, but they both knew she was teasing him on purpose.

She continued to "accidentally" touch it a few more times, and once even rested her forearm on it while pulling a strip of wax on his inner-thigh.

Her attentions, as slight as they were, combined with his humiliation, brought him to the brink of orgasm.

He tried to hold it in, to focus on the pain. He couldn't stand to think of the humiliation he'd experience if he came in his tighty-whities in front of these strange women.
