Schoolgirl pin

Your mom quickly climbs up your body, at a speed you didn't know she was capable of, and sits down on your neck. She presses her thighs against your ears as her damp crotch makes you struggle for air. She reaches back and pushes your legs down, gripping your thighs with her soft hands.

She scoots forward slightly and her crotch presses hard against your chin, forcing your jaw closed.

You try to take advantage of your newly freed hands but soon realize that her legs are pinning your arms down, and they're starting to feel numb.
