I've Heard You Wanking

Shouldn't you be at College?! You've come home at lunch because you can't be bothered with the lessons... When you get home your step-mum is at home doing some cleaning, so you try to sneak in quietly, but she catches you! She threatens to tell your Dad, but she's had enough of you. "Get your COCK out", she tells you. She's seen you looking at her the way you do... She's heard you WANKING over her at night.
