You've been a bad boy, sneaking around with that trampy girlfriend of yours. But not tonight, sweetie. Not on my watch. I'm your step-mother, and I know what you need better than anyone. And tonight, you're all mine. You're forbidden from seeing that no-good girlfriend of yours. Instead, you're going to fuck step-Mommy. Lie back, relax, and let me ride you hard. You're only allowed to cum for me from now on, and I'll make sure you do just that. Feel the warmth of my body as I trick you into filling me with your seed, marking me as your one true source of pleasure.
