Your big sister comes into your room to confront you. "Do you know what this is about?" she tells you she knows you have a crush on her... it's pretty obvious, you can't stop staring at her tits. She tells you not to be embarrassed - she just wants to talk about it so the two of you can find a way to deal with it. "I think the best solution is just to get it out of your system. Do you know what I'm saying?" she wants to make you her little sex toy... but first, you'll have to prove yourself. "You're going to have to be a good boy and do everything your big sister tells you to." She decides your test is going to stroking your dick to your big sister's tits, following her instructions exactly. She edges you for over 20 minutes, dirty talking and rubbing her tits in a way that makes you wonder if you'll be able to control yourself. She makes you TASTE YOUR OWN PRECUM to prove your obedience. When she decides you've earned your orgasm, she instructs you to lay back with your legs up and CUM ON YOUR OWN FACE. If you lasted, she has much more in store for you... big sister has needs of her own, of course. As your sex toy it will be your job to serve her and be used for her pleasure. ***this video has no verbal cum countdown but there is a 20 second countdown in the corner of the screen to follow while I tell you how to stroke yourself and cum on your own face***
