In my teenage years, I would get erections during class even if I wasn't thinking about sex. If you had a big-breasted, kind, and very naughty teacher during that time, you'd be standing up and leaning forward in the morning! The new busty teacher, who was in charge of the class for the first time, uses her body as a weapon to give a full-body sex lesson! Titty fucking class, masturbation supplement, and a reward if you get 100 points? If you're told that, you have no choice but to work hard! If you had a school like this, you'd want to keep going without missing a day! It's a school life that's so enjoyable!
