Koakuma Katekyo

The protagonist was a shy college student, especially around females. Hoping to overcome this character trait, he accepted a part-time job as a home tutor. His student was a young girl named Yui Katou. She was a little bit dumb and sexy, like a diminutive "gyaru". As he taught her, the protagonist's eyes were drawn to Yui's small and lightly-dressed figure. When she caught him looking she smiled in a strange way. "Sensei, could it be you're a lolicon?" Yui was more sexually experienced than he had guessed. "Fufu, in that case Yui will take sensei's virginity."
