No! Your fingers are grinding against me! My cousin, who's also a teacher at my school, Kyou, is going to stay in my house!? My beautiful sister, who doesn't have a boyfriend, seems to like Kyou! I'm planning to help bring them together, but... I became interested in Kyou and made a big mistake!! He tickles and touches me while trying to tease me... but then, he starts to rub my breasts, caress my butt, and even touch my private parts!? I don't like it, but he gets the wrong idea and stimulates me even more! Finally, Kyou who has been lustful, is going to cross the line that should never be crossed!?
