Your cock is caged

You pull off the sheets and look down in horror to see your cock has been locked in a pretty, pink plastic chastity cage. You struggle to open it, which only sends painful pangs throughout your body. You whimper in frustration and go to find the asshole that has the key to your release. You slip on a tshirt and sweats and head downstairs.

You find Brad in the kitchen, casually eating a bowl of cereal wearing nothing but a smirk. "Hey, little sis, what took you so long? I thought you were gonna sleep all day." You are ready to read him the riot act, but then he swivels in his stool, and you can't help but notice his cock seems to have been waiting for you to wake up too. Fully erect, jutting in the air, a perfect pearl of precum glistening on the tip of his cock. You feel a painful throb in your cage before you **** yourself to look away with a whimper.

"That's right, sissy. Your little clit and cum belong to me. If you want relief, it's going to come from my cock milking your sissy cunt. And I have all week for you to beg for it. All week to break you and make you my bitch. And the longer you take to beg, the harder I'm going to make you work for it." Brad grins cruelly, you know he expects you to give in and beg for him to make you his bitch here and now.

A part of you sees his point. You almost surrendered yesterday without this added "motivation" what hope do you have to last the week caged and longing? On the other hand, if you can manage to hold out, you can show your parents what a creep your brother is and maybe finally put him in his place.
