introduce that girl to your friends as your sister. make it risky. make it real. she is your sister, and now everyone else thinks so, too.

so you have to be careful. you have to hold back.

you have to let every fucking carnal desire in your heart and body build up until you're about to break, anytime you're around your friends you have to either keep your hands to yourself or find ways to sneak kisses and cop subtle feels

until you two are alone and you can tear her apart. look at her, she knows you're waiting, why else would she smile like that, the brat.

fuck her. do it. fuck your sister, you freak.
