[Yamanouchi Yuu] Misao no Keiyaku - CHAPTER 1-12 (English)

A shy male student is forced into a compromising position by a confident teacher who brandishes a key tattooed on her thigh, promising freedom in exchange for compliance. The classroom setting turns tense as she commands him to obey, her breath hot on his skin while he stammers, caught between desperation and the threat of exposure. The uneasy power dynamic escalates, hinting at a deeper, possibly binding agreement that will test both their limits.
