[Tansan Protein no kai (Tansan Protein Kashiwagi)] Change Sex and Become a Sex Slave [GTF]

A gloomy young man, dumped by his girlfriend after yet another joyless hookup, whispers a desperate wish to become a girl and finally live a life of value. His transformation grants him a cute new body with a bouncy ponytail, but the world awaiting her is far crueler than imagined—a commanding man in a suit snaps handcuffs around her wrists, collars her, and delivers the trembling virgin to hired men who delight in breaking in fresh girls. What began as a longing for beauty spirals into a nightmare of restraints, tears, and submission she never agreed to.
