Cruel Roommate

I've recently joined university, and it's been great so far, apart from my slut of a roommate Amy, who seems to have a different guy every weekend, which I find disgusting. I am totally the opposite to her; I am still a virgin at the age of 19, and even though I get a lot of attention from guys, I'm not interested in a relationship yet or casual sex.

I come back to my dorm room, and there is another guy about to leave. I've had enough, so I decide to lay down some ground rules. Later on, when I explain how I feel to Amy, she goes crazy and tells me that she will set some rules herself.

I almost felt like laughing and storming out, but as I tried to stand up, I couldn't move. Amy then says "This is what is going to happen. I will control your life from now on, but I will try to give you as much free will as possible. If you complete the challenges I give you, the more control you will have. Your first challenge involves you naked in just a towel, so go get changed".

I found myself standing up and walking to the bathroom, unable to stop myself. I can't believe this; how is she doing it?
