During puberty, my dick was always rock-hard even without thinking about sex, making it embarrassing just to go to school. Around that time, there was a big-titted, kind, and super horny teacher who made the school's atmosphere increasingly perverted. If your homeroom teacher was the fair-skinned, busty, and gentle Itsukai Mei, you'd start taking your studies and club activities seriously. You'd show up for extra lessons every single day if it meant getting a sexy reward. Once you're invited to one-on-one titty fuck tutoring sessions or private sex training, there's no turning back. What kind of teacher rewards hard work by letting you grope her breasts? With a teacher like her, you'd never skip school—perfect attendance would be guaranteed.
