You knew she'd be desperate to end the bullying, but you didn't think she'd be THIS desperate! When that twerp's step-mom called you to come over, you figured she'd be angry, above all else, considering all the horrible stuff you've done to her precious boy, but she was more sad than anything else. Begging you to stop, not to bully her step-son anymore. You can tell she'd do anything. Anything at all. And her heavy tits have your mind running. You've always thought she was total smokeshow, an absolute MILF, and now is the perfect opportunity to get what you've always wanted. "I can't believe you would even ask me that--you're far too young to know what that is!!" She acts indignant, but you know she'll do it. Anything to stop the bullying. Of course, once she agrees, you've got it in your head to move the goalpost. Its only nature. Give a boy an inch and he'll take a mile. Or, give a bully a blowjob and he'll demand you fuck his cock like the hidden slut that you are. Same saying, really...
