I am to watch my sister Mina's punishment. She is without sin, this is to be a reward.

Naked, unafraid, she stands as our latex-clad mother begins.

I, too, am naked and forbidden from touching myself. That is my punishment.

Silence, just the liquid sounds as Mummy's fingers do their work. Mina catches fire quickly. Her neck and chest soon flush red.

My own body is responding fiercely, but I dare not move. Mina is biting her lip to stop her whimpers from escaping.

Now the agony begins, for if Mina moves or makes a sound, Mummy will stop immediately.
