You're all alone at home since your parents are gone and your sister is sitting in her room getting bored, the same as you are, so you think maybe it's time to go to your sister's room and keep her company. That way you could both entertain each other and make the time pass faster. Biiiig mistake, as the moment she sees you in her bedroom, she already starts plotting and coming up with strategies of how to use you and take advantage of you. So she suggests you play a little game: you have to come up with a word starting with the last 2 letters of the word she said...then she will do the same and it keeps going until one of you loses. Guess who will end up losing and gets punished with farts? hahah that's right, you! And you will end up getting trained to actually like farts and develop a brand new fetish :P
