Sissyfication/Feminization: The term sissy when referring to a man, is basically a man who does not measure up to being an alpha male, strong man, independent and knows how to take care of a woman. Could be his penis is under 5 inches, or he cannot cum like an alpha male and sexually satisfy a woman; or, he is a bottom and has a yearning for sucking cock like a cum slut.
Along with that feminization process for a true, real sissy, involves dressing up sissy in sexy, slutty lingerie such as a babydoll lace teddy, lace panties and a bra. Then stockings and high stiletto heels. A chastity cage to hide that embarrassing excuse for a penis. A wig and some makeup. Mistress will dress sissy and make you my bitch.
