My girlfriend, Meru, is a blonde nursery teacher with a good reputation. She's loved by both children and parents, but for some reason, she's strangely cold towards me, her boyfriend. Even when I tease her, she often ignores me or treats me coldly, but I never give up. That's because I know that when it comes to sex, Meru becomes all lovey-dovey...! Despite being a total tsundere, she accepts everything when it comes to sex, and I live together with my slutty girlfriend in a sweet way!
