Be good, or you might get punished… Everyone looks up to Ayaka. She`s one of the most beautiful professors at the academy, with bright eyes, big breasts, and a brilliant smile. But she`s got a tough side, too: she`s coach of the Karate Club. Treat her well, and you`ll be rewarded with all sorts of sexy favors… but get on her bad side, and you`ll be flat on your back in no time. So far, there`s only been one guy bold enough to anger Ayaka: a brash new student named Togawa. One night, he finds Ayaka having a one-woman orgy in the gym shower room and decides to step in. Will Ayaka`s temper flare up once again, or will she be swept up by her lustful desires?
