Fuck her. Hard.

It's time. You take a deep breath as you line your cock up with your mother's sodden slit. Your gaze drifts up, across your mother's taut belly, past her voluptuous tits, until you lock eyes with her. Wordlessly, you ask her what she wants. She groans, sliding her lips up and down your cock, pleading with her eyes.

"Please, Riley. Please."

You slam in in one go. Your mother screams as you hilt yourself in pussy.

"OH! Riley! More, please!"

A thought crosses your mind: your mother's tits grew when she thought of you. Certainly, turnabout is fair play?
