Your mother has always been willing to give you anything you want. Clothes, toys, trips...even herself. To a degree. You've been using your allowance to buy her slutty clothes, then faking sick, waiting til dad leaves, and getting hot, juicy handjobs and feeling her warm wet mouth all over your cock. For a while now. And its time to escalate things. Sure, she didn't want to jerk you off at first, until she felt your cock pressing against her, through your pajamas, that one morning last year. And sure, she didn't want to suck your cock at first, but once she felt you throbbing against her lips during your morning milking ritual...well, she didn't have much choice. Today, you know it will only take a little convincing to play a fun game of "just the tip." And you know mommy is your slut. You know that it won't take long before she's buried on your cock, cumming like a good little whore with her son's cock in her pussy.
