Synopsis
Yuzuki had abandoned his pride as a man and his mother to become Seiji’s “female.” But on a night of the full moon, his body underwent a strange transformation.
Yuzuki’s lower half had become female (a cuntboy). When Seiji discovers Yuzuki is still a virgin, his attitude drastically changes.
“I must mark you as mine right now so no other man can take you.”
Seiji, overcome with possessive desire, penetrates Yuzuki without mercy. Unprepared and defenseless, Yuzuki’s unknown body is claimed relentlessly.
“I’m already your female… why won’t you believe me!?”
Yuzuki trembles through pain and sorrow. “I needed proof that you belonged to me, no matter what.”
Melted by this clumsy confession, Yuzuki surrenders to an obsessive, all-consuming love and falls into feminization once more.
Seiji’s possessive overwriting of feminized Yuzuki—obsessive domination × possessive desire × forced re-feminization.

Editorial Review
This is an advanced entry in the feminization-focused BL subgenre that hinges entirely on escalating possessive dynamics and non-consensual defloration as emotional catharsis. It operates within a niche but thriving market segment where consent ambiguity and forced scenarios function as vehicles for exploring devotion rather than straightforward power fantasy.
What distinguishes this installment is its supernatural reset mechanic—the involuntary bodily transformation serves as narrative justification for re-establishing virginity and restarting the dominance ritual. This gives the work a cyclical obsession structure uncommon even within forced-feminization circles. The stepfather-stepson dynamic compounds the already-transgressive appeal, and the 53-page length suggests sustained focus on the psychological collapse rather than rapid-fire scenes. The tags paint a coherent tableau: forced entry meets possessive jealousy meets overstimulation as proof of ownership. Seiji’s confession that he “needed proof” pivots the assault into an act of insecure devotion—a framing choice that positions brutality as communication failure rather than sadism, which is precisely what keeps this subgenre’s core audience engaged.
The recurring series element matters here; this isn’t a standalone. Readers returning to the “Seiji Father × Feminized Yuzuki” universe will recognize the relationship’s previous trajectory and interpret the re-feminization as narrative deepening rather than repetition, though newcomers will grasp the setup immediately.
This work caters specifically to readers who eroticize feminization through loss-of-agency scenarios, who find possessive obsession structurally erotic, and who value psychological capitulation over physical description. Approach contingent on your tolerance for non-consensual defloration framed as proof of love.
A focused, deliberate execution of its premise—essential reading for enthusiasts of possessive-obsessive dynamics in feminization contexts, disposable for everyone else.
