The students were on top of their exams when they came to the teacher's house. They talked and showed off their tender young bodies. Then he decided to fuck them each in the mouth, but at the same time. While he grilled one, the other was always there, stroking and encouraging. The instructor, by the way, is no fool - he has the girls in their asses, anally, not bothering to work out for long.
Watching your wife suck other people's dicks is a buzz kill. And she understands that by licking other people's testicles, her husband's boner will get sharper. So these swinger couples swap to sharpen their senses, bring back the novelty, and make their orgasms brighter. Only I would make the lighting not so bright, then there would be more understatement and less embarrassment.
Who would do me like that?
