Synopsis
Reiko Yumiooka, a 27-year-old female dentist, runs a dental practice in an apartment with her 21-year-old sister Kyoko as an assistant. One day, a robber breaks in, forces the sisters to strip naked, and takes over the apartment. However, Reiko has a promise to meet with her mentor Masaki regarding financing, and is permitted to leave on the condition that her sister remains as a hostage. Masaki demands Reiko’s body in exchange for the financing. As Reiko calls her sister, Masaki thrusts violently behind her, and she gradually begins to moan. Meanwhile, hearing her cries through the receiver, the man becomes aroused and assaults Kyoko. Moans leak from both receivers. Reiko returns to find the sisters bound and asleep. She unties Kyoko, but the girl, now captivated by the man, does not attempt to escape. When the man wakes up, he rages and assaults Reiko. The sisters gradually become enslaved to him. A news report reveals the man’s face—he’s a loan shark robber. His bag contains 30 million yen. The sisters and man attempt to flee by car, but the police net closes in. In the apartment garage, Reiko drives off, abandoning the man. As he chases after her, she reverses the car, trapping his legs against the wall. Days later, in the apartment, the immobilized man is surrounded by the clinging sisters.
Editorial Review
This is a Nikkatsu Roman Porno title—a theatrical adult film from Japan’s most storied exploitation studio—not a doujin work. Henhenta reviews independent, self-published works available on DLsite and similar platforms. Roman Porno films are professional studio productions with theatrical distribution, which falls entirely outside our editorial scope.
If you’re looking for reviews of adult doujin works, we’d be happy to assess independent titles in that space. Doujin adult content typically includes digital comics, animations, visual novels, and CG collections created by independent circles and sold through platforms like DLsite,FantiaFantia, or similar venues. These works occupy a distinct market position from studio-produced theatrical films.
Should you have a doujin title to submit—whether it’s a digitally-distributed visual novel with confinement themes, a CG set exploring similar power dynamics, or an indie animation—we can provide the kind of specialist analysis our readers expect. Our reviews focus on what independent creators bring to niche genres: distinctive art direction, innovative narrative structures, production quality relative to doujin standards, and how they compete within the crowded independent market.
For now, this submission falls outside our coverage area. Please resubmit with a doujin work, and we’ll give it the focused critical attention it deserves.
