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.
The lady is gorgeous, pure sex! Such can inspire a man to sexual exploits even if he is very tired at work! But I would not advise to go on business trips with such a sultry friend, she obviously can not do without sex for a day! It's good if she is good with a vibrator, and if not?
Baba should be fucked just like this man does, that is, to drive a big cock into her pussy and start fucking the sweetheart with such force that she was stunned with pleasure. And then he'll dump his sperm on her, too.)
