Force Anna to eat your cunt
From Create Your Own Story
You grab some rope nearby (you've hidden various things, including rope, around the house for easy access to them) and tie your mother's hands and feet together. She appears to be hurting too much to escape anyway, and just looks at you with fear in her eyes.
You squat over her face and shout, "Lick my dripping pussy, bitch!" Your mother starts crying, so you punch her in the stomach. After she gets her breath back, she hesitantly complies and places her tongue on your pussy. She moves it up and down slowly, but she's a thoroughly horrible rugmuncher.
