[Inashita Shinai, Seiji] Tensei Shitara Joban de Shinu Naka Boss Datta - Heroine Kenzokuka de Ikinokoru vol.1

A reincarnated mid-boss doomed to die at the start of the game gambles his survival on turning the heroines into his devoted possessions. His coolly disdainful maid Alice insists she has no interest in her master's schemes, even as he abandons the assassination plot that seals his fate and tests a strange, heat-inducing medicine that leaves her bare body flushed, trembling and exquisitely sensitive. Caught between a voluptuous, heavy-breasted demoness marked with a lewd womb tattoo and his once-icy servant's slide from disgust into aching, obedient submission, the new demon lord must master seduction and control to rewrite his ending.
