Nếu mặc áo sơ mi của anh kế của tôi mà không được phép

My beloved, kind stepbrother. He found out I was secretly wearing his shirt. So today he's going to punish me again. I'm blindfolded, my hands and feet are tied, and he's using a vibrator. My heart races every time, wondering when he'll turn on the vibrator while I can't see. I like being left in an embarrassing position and being watched by my stepbrother. I also like my stepbrother scolding me.
