Nothing, that there is no way to get a boyfriend, as soon as the girl meets a boy he wants to fuck his sister so that it is clear to him that only he knows how to give her a lot of pleasure.
The boy knows that his days with his little sister are numbered and that sooner or later she will “fly from the nest” and go to live with the boy she likes, that’s why she wants to drain her last cartridges and not miss a single one opportunity to throw it. At least the young woman will go calm and relaxed to her date because after this powder I do not think she wants to have sex that night, or maybe yes….
