Ryoko Asamiya, a big-breasted mature teacher, sees male students as men and actually gets excited during class when there's a student she's interested in. Ryoko is a dangerous teacher who continues to give one-on-one lessons while making sex appeal by twisting her body. At first, he takes the student's hand, who is a little timid, and lets him touch his skin directly, then opens his thighs and continues to seduce him, and begins to forcibly caress him. The male student, who was hooked during her operation, could not contain his excitement and inserted it on the spot. Changing the location to a gymnasium, the two of them heighten their already cold excitement even further, and do it again in a closed room where their moans echo.
