"Mommy's Girl" has a rather limited and repetitive format (that fans dig) consisting generally of a hot stepmom making love to a petite stepdaughter. This segment varies that structure, with two extra MILFs in the cast providing a lengthy all-girl sexual 4-way.

Serene Siren is the stepmother, showing off a selection of newly designed gym uniform for girls aimed at being more flexible and durable garments.

Her teenage daughter Sophia Burns tries on the new uniforms and even undresses and dresses in front of mom and her friends Ember Snow and Syren De Mer to show them the fit. Everyone gets turned on and soon it's group sex time, all-female.

The level of eroticisim here is impressive, making up for the merely token set-up material.
