Something tells me that the title is a little wrong, but never mind, the point is that they fuck great and despite the fact that the guy's dick is not particularly big, he managed to bring her to squirt, is this not an achievement, I think very much so. It's nice to watch, the lady is jumping around, riding the guy, as it should be, and he is not lost, helps to reach the peak of pleasure.
The sister is not shy with her brother - he has known and used her body for a long time. She often bailed him out while he didn't have a steady girlfriend. Now he has a girlfriend, but he enjoys pleasing his little sister. And he always comes only in her mouth - she loves the taste of sperm.
