A scared sister leaves you alone

Amy’s face crumples and she flees.

Alone now, you surrender to the climax that’s been building within you for the last minute. Moaning, and with your eyes screwed shut, you ride out the spasms which engulf your body.

Afterwards you lie on the carpet as your breathing slowly returns to something like normal and the sweat dries on your body.

“Amy? AMY..”

Great. You’re still tied. And now the one person who might have helped you has run off.

You consider two choices. Look in your room or try to find some way of freeing yourself. You're sure that you can make it up the stairs, even with your hands tied behind you. But once there, what then? You can't stay in your room for ever. But perhaps Amy will come back.

Suppose you try to find something to cut yourself loose?
