Something wakes you up.

You're roused from your sleep by a strange feeling, as if something is wrapping itself around your ankle. But that's silly. You shake your leg to shift your covers and make the feeling go away, but the feeling just gets tighter. Then another warm thing wraps itself around your other ankle like a rope. At this point you think someone is trying to tie you up, so you kick out with one legs, but your foot never hits anything, just empty space. Then you feel a firm pulling your ankles and you're wisked out of bed, the covers falling into a pile below you. You're being held upside down by the ankles, and your loose shirt falls down around your head, blinding you and exposing the rest of your body at the same time. Your nipples stiffen at the touch of the cool air, bouncing upside down as you're jerked around, and your crotch feels very despite the panties covering it.
