My Teacher Is Extreme Sadist, and Horny Beast

"Your body's the only thing that matured." Even though class is still going on, his long finger slid between my legs and rubbed my sensitive spot... This is the first time I've felt pleasure like this. It's overflowing! Tomoru has feelings for Chitose, the P.E. teacher and her childhood friend. She's been trying to get his attention ever since she was little, but he'd always brush her off. Tomoru, who couldn't restrain herself anymore, tries to seduce him in order to make him look at her... then suddenly, he starts greedily eating her up as if he had turned into a different man!
