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.
What better way for a girl to get a hot massage than to hold on to the masseur's dick? Only to take it in her mouth. And not much time passes between these two actions. Because the skillful hands of the masseur ignited the female in her, ready right there on the table to copulate with him. Only an orgasm and a stream of cum can dull this fire. And it seems that the guy succeeded - he cum right into her vagina.
Sucking is normal.
