[Follow up from: Sister edging JOI] Your sister gets all dressed up to spend a late Valentine's Day with you but finds out you went out with your supposedly EX-girlfriend. Didn't I tell you to break up with her bro? This isn't going to end well for you. I lightly blackmail you into doing what I say. I tell you exactly how to jerk that cock for me while teasing and edging you. You didn't think I'd let you cum that quickly... or at all?? I tease you, even more by giving you an oiled up assjob and making you call your girlfriend and break up with her right there. I'm still not going to let you cum bro, but you'll not make the mistake of going back to that slut again. Your sister knows you best.
