Synopsis
A story from when Makoto was an intern at the academy.
Suzukaze Yurina is a popular art teacher instructing students in drawing at the academy’s art studio. She is married, though her husband works alone in Italy on business.
When her father, who owns a gallery building, falls ill, Yurina decides to stay in Japan until his condition improves. Through an introduction from Sakakura, a senior from her university days, she takes a position as a temporary teacher at the academy. She enjoys friendly interactions with students during club activities.
Sakakura, a chemistry and physics teacher, has been independently researching a secret drug since university. He now uses it for conditioning experiments on academy staff and students. The underground conditioning room in the abandoned school building is under his management, entrusted by the director.
Sakakura has harbored an abnormal obsession with Yurina since university and has been plotting her conditioning. When he broaches the conditioning plan to Yasano Shiro, another teacher he’d been watching, Yasano reveals his own interest in Sakakura’s activities and that he’s targeting Makoto, the research intern.
Finding common ground, the “Yurina Conditioning Plan” is set in motion.
Days later, Yurina is ordered by the director to attend an exchange training session. On departure day, Sakakura offers her tea. As she finishes drinking it, he tells her the training session doesn’t exist. Shocked, Yurina tries to stand but her legs give way, her vision darkens, and she collapses.
Yurina awakens to find herself restrained naked in a conditioning chair, a ball gag in her mouth, her nipples and clitoris coated with the secret drug, kept in an aroused state.
As Yurina struggles not to lose consciousness, Sakakura delivers the final blow: she will be confined in this conditioning room for two weeks of training.
Yurina is horrified. She faces what seems like an eternity of vile conditioning.
★★★CHARACTERS★★★
■Suzukaze Yurina (Age 26)
Daughter of a wealthy gallery building owner. From childhood, surrounded by paintings, her dream was to become an art teacher. She obtained her teaching license at university, then studied painting abroad in Italy, where she met Yanase Keigo, a trading company employee, and married him. They lived together in Italy.
Years later, when her father fell ill, she returned to Japan alone while her husband remained in Italy. She stays in Japan temporarily until her father recovers. During her extended stay, she was invited by Sakakura, an acquaintance from university, and her dream was…
Editorial Review
NTR doujin centered on coercive scenarios have become increasingly mainstream on DLsite, but this work distinguishes itself through its institutional setting and the deliberate construction of plausible access routes. Rather than relying on chance encounters, the narrative establishes Sakakura’s position of authority—chemistry teacher with unsupervised control over an abandoned building—as the foundational mechanism for the conditioning premise. The drug-use tag combined with captivity creates a scenario that prioritizes psychological breakdown over conventional seduction, marking it as part of the harder end of the NTR spectrum.
Yurina’s characterization as an established married woman temporarily separated from her husband (stationed in Italy) provides the narrative breathing room NTR works require; her temporary teaching position introduces her as accessible but not permanently embedded in the protagonist’s social world. The art teacher profession and large breasts tag suggest conventional visual appeal, though the synopsis trails mid-sentence, leaving unclear whether this is a narrative choice or a technical limitation. The “conditioning” tag structure—repeated drug application in controlled environments—indicates this isn’t spontaneous infidelity but methodical psychological transformation, which appeals to readers seeking escalation mechanics over immediate conquest.
This work will resonate most with readers who prioritize scenario plausibility and institutional power dynamics within NTR frameworks, particularly those interested in the conditioning-over-consent subcategory rather than traditional blackmail or coercion narratives. The chemistry teacher angle provides thematic coherence absent in more generic scenarios.
A solidly constructed institutional NTR entry that leans into psychological conditioning mechanics with enough structural specificity to justify its premise.
