First, total emasculation

Natalie bound the sissy to bondage cross such that her legs were spread wide and she could barely even wiggle in the restraints.

“You think you are a man. And at the moment, that is true. All of this.” She said, gesturing toward Danielle’s outfit and cage, “is an attempt at immersion-based sissy training, a style I reject. All the frilly dresses and new names in the world don’t change the fact that you are, for the time being, a man with what is quite frankly an average sized dick.” She removed his cage. “The reason you are being made a sissy has nothing to do with your penis, because while it is pathetic compared to a futa’s, so is everything else about you. Look, your even getting erect.”

“A male erection is an act of agression. It means you desire sex, but no woman in her right mind would ever have sex with such a pathetic six inch dicklet when futa’s offer them so much more. So to fulfill their desires men **** women to fuck them. You bastards are clever though, you don’t always use physical ****, but through guilt or guile or social pressure you all seek to **** women to have sex with you, and therefore every time a male uses his cock on a woman it is ****, and that erection is an expression of your desire to **** me.”

She then slammed her knee into Danielle’s crotch, cutting off the sissy’s protesting grunts in a agonized, muffled cry.

“Men,” Natalie said, “are inherently destructive, violent, aggressive, evil, and insane. What I do now is to cure you of your insanity. But to do that I cannot merely cover your evil, masculine self in a veneer of femnity, as your doctor and much of the medical establishment tries to do. Instead I must destroy it, I must remove it from you. I would do this literally, but your mother has requested you keep your worthless man cock. So instead I shall do the next best thing.”

She reached down into her bag and pulled out a syringe and another cock-cage, this one far smaller and made of metal instead of plastic as the last one had been. Dannielle’s eyes widened in fear.

“This,” Natalie said holding up yhe needle. “Is a two in one localized testosterone blocker and numbing agent. I use it as the next best thing to gender reassignment. It will keep you from getting erections, and while it won’t prevent orgasms, it will render them totally pleasureless. It’s sadly reversible, but it lasts indefinitely.”

She inserted the needle into the sissy’s scrotum and injected it. “There goes that filthy erection.” She then strapped the cage on tightly around Danielle’s limp, shrunken dick. “Between this and the estrogen therapy, your sissy body will be all taken care of, so all I need to worry about is giving you a proper sissy mind.”
