The Girl's on her rag so obviously you have to fuck her in the ass. So you blow your load in her ass hole, and you pull out real quick and punch her in the ovaries, causing her to excrete period juice, as well as the shit and cum already in her ass. The remnants of this is a big red white and brown mess all over her parents bed, hence "The Neopolitan"!
"So the bitch tries to get out of it by telling me shes on her rag. So I gave her the neopolitan treat".
