The sisters are totally different - one is active and energetic, and the other is quiet with glasses. And the second was afraid to have sex with a guy - even her panties were not sexy. But still even she got aroused when the guy started fucking her sister in the asshole. She licked his dick before doing it and started squeezing his balls. Just like that, the quiet girl joined in. And I hope she didn't regret it. The main thing is to start and suck in time!
How all the girls love young tutors, they apparently drool at the sight of these men with pumped arms, so they give him all the passion, in principle, not surprised.
