You were caught making out with boys at school and they told your step-mom. She scolds you for getting caught and prompts you spill all the details. You confess to going further and that only seals your punishment. If your going to be sucking dick then you need to do it right and not get caught. Fucking your throat with a long dildo until she's satisfied you've learned your lesson. Making you apologize with a cock in your throat. Promising that if you're caught again to bend you over and use your other hole just as harshly.
