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.
Beautiful and very tender sex, without fuss and unnecessary hurry, it is obvious that the man is sure that this lady got him not for the first time and not for the last. This is how couples who have been married for more than a year can fuck, the first passion is over, and all that is left is the calm certainty that good sex is guaranteed!
