Запертый взаперти для твоей учительницы

It's not always easy to pass all exams, especially when your teacher is as demanding as I am. But let's just say that you still have a chance of getting this sorted, as long as you do as I say! If you're a good boy and follow all of my instructions, nothing bad is going to happen, and I'll find a way for you to pass. But there will be a couple of sacrifices you'll have to make to convince me that you really deserve it! For starters, you'll have to put this chastity cage on and then show me how well you can worship my body! All under my instructions and careful not to cross any limits, little one!
