There's one thing you HAVE to do if I'm going to let you cum today. You're so horny and eager to start pumping, you'll agree to whatever it is! Are you sure? You have to do whatever step-Mommy says. You'll have to ruin your load. Ruin it. This will be a pleasureless orgasm and it will drip pathetically from your cock while you watch and Step-Mommy laughs.
