Well, first of all, forced feminization can be of two rather different types. It can either be by a man for the purposes of gay sex (as sometimes happens in jails - which is usually non-consensual), or it can be by a female dominitrix for the purpose of humiliating her slave so that he submits to her more.

The femdom scenario is always consensual, as the man is always free to walk out the door and escape the situation if he chooses to do so. He may be totally submissive, and therefore unlikely to do this, but he still always has a choice. All non-consensual

Forced Femme of Slut

He hurried to get to the department store. Somehow he had a very good idea that being late tonight would not be forgiven, not dealt with in a pleasant manner. The parking lot was full and there were no places close. It was raining and he had not gotten to leave work early as he had planned. He could feel a tiny knot of terror building in the pit of his stomach as he tried to get inside quickly and get the make up items that lori had faxed over to him. He also had read the postscript that said that if he was asked whom the makeup was for, he was to say it was for him. All he could do was pray that no one asked him, as he was not certain he could say that. He also was not certain he could continue to shave as he had been instructed by Madam, he could already see problems with that if he did. It was not a big deal to keep his cock and balls shaved; he had grown to like the feel of them against his underwear, finding it arousing. But his legs and armpits?

He finally got into the store and found the department that he had been instructed to go to by lori. The young girl behind the counter had just taken the sheet of paper from his hands when he tried to tell her he needed these items. A few times she had glanced back at him as if to ask a question and then had not, returning to gathering the items that had been listed. She returned back to where he stood and showed him the various items one at a time. Explaining how to apply the dermacare makeup and how that he would need to shave very close prior to applying it. He could feel his face growing red as she continued on with her explanations. She finally looked up at him and smiled.
