[MM] Kiss-loving Mei-chan

Mei has turned allowance negotiations with her big brother into something far more dangerous—a deep French kiss in exchange for pocket money, with the promise she masturbates thinking about it afterward. What starts as a teasing transaction spirals into full femdom territory as she straddles him, big breasts pressed against his chest, mocking him as a pervert even as fingering and grinding leave her crying out in pleasure. A flashback reveals she has been shaping him into a devoted boobs-man since childhood, and this yandere little sister's obsession clearly runs far deeper than spare change.
