After stacking Sophia's ass over Katherine, Zed started alternating between their pussies. He made gentle love with Sophia while getting in fucking-mode once inside Katherine.
Sophia felt the balls slap on her ass as he slammed into her mother. The sound of flesh hitting flesh overpowered everything, even the moans of pleasure.
Such high intensity of the strokes surprised her, but she theorized it must be her mother's instructions.
She must be making them learn something new!
This made her cunt gush from fear and anticipation.
What must hardcore fucking feels like?!
Surely she would be able to handle it if her mother can!
Afraid but also excited, she nuzzled her lips on her mother's neck, nibbling on the sweet-tasting skin. Simultaneously, she reached for her mother's ample breasts.
They were soft and pliable and yet also firm! She couldn't help but squeeze them together.
