humiliated amp blackmailed by big sis:

Hey there little bro! I know you’re a little perv who’s been spying on me ever since our parents got married. You think I don’t know? silly boy. I hear the fapping sounds every single night. I’ve just decided to ignore it all this time. But I’m tired of you being a little horny shithead, I’m going to show you what a true orgasm is. But you’re going to have to give me something in return… Otherwise, everyone will know about your dirty little secret Cru.sh on me.
