Une demi-sœur salope pète sur ton visage

Your bitchy step sister is playing on her phone when you enter her room asking if she could help you with the French homework. Since she is fluent in French and you're not, she starts teasing you about being a stupid loser who can't speak a word of French and tells you that if you want her help, you will have to play by her rules. Whenever you don't write something correctly in French, you get punished with farts, that is. So, do you wanna get this essay done or not? You know you wouldn't be able to write it on your own, so shut up and put up with it!
