The teacher is pretty advanced - letting students fuck in front of her and giving her advice is cool. Sure, the student was a little shy at first, but that passed quickly. I, too, think we need hands-on sex lessons, then it will be proper and safe. And still the guy cum on the boobs of the teacher - after all, the students have to somehow thank her for teaching them.
Yes, she only looks puritanical and prudish, but look how her eyes lit up when the bucks waved in front of her! She wanted to hold that dick herself. ))
