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.
Vulgar slut with a pimply ass and an impossibly fucked up front. Personally, I like to fuck sluts, too, and I fuck them with a condom. But kissing her labia? The man is clearly wrong! He'd rather put his dick in her anus! I don't mind mutual oral caresses, but you have to be more careful when choosing ladies. And vulgar, slutty ladies are only good enough to give them in the mouth and to fuck them well, always with a condom!
