It's a good enticement, if you spin such a screen saver at the entrance to the brothel, there will be no shortage of customers. In fact the lady does not really please herself, but only demonstrates her body and temperament. By the way, the body is only a four, but the boobs are great!
And why the girlfriend was so turned on - he was her half-brother, not her own. And who's gonna train his sister, a stranger's uncle? No, only your own should be trusted with her pussy.
