Tied up & Made to Cum

I wake up and find myself completely tied up and gagged, and unable to move! What's more, there's a magic wand tied to my leg. I am freaking out and trying to make sense of the situation when it suddenly starts vibrating. Omg!! There's only one person in the room, you, and you're just sitting there watching me. This is super scary, but also surprisingly arousing... My mind switches between wanting to escape and wanting to enjoy it. Eventually, I manage to get rid of the ball gag and start begging you to let me go. Please?! I cannot hold my orgasm any longer, and I cum hard, even though I'm not sure if I want to. Wait, where are you going?! You can't just leave me here!!
