Forced Feminization Frenzy: Ossan Ka Kusuri's 40-Page Masturbation & Leotard Fantasy
The grotesque beauty of **Ossan Ka Kusuri** unfolds as our transformed office worker discovers her leaking nipples respond to phantom male urges, forcing her to ride sybian machines until her new pussy squirts across the page. Each panel escalates the degradation—from anal beads stretching her virgin asshole to public masturbation scenes where strangers finger her swollen clit.

This gender-bending spiral crescendos with a Dionysian orgy where multiple possessed bodies merge into one writhing flesh-pile of ecstasy. Readers craving more reality-warping erotica will cream their pants over Forever a Bride, another masterpiece of erotic metamorphosis. Not since Motto Motto Senpai has a doujin so viciously fucked the boundaries between pleasure and terror.
