Ivy keeps licking Adira, looking for signs of her proof.

She sees that Dee has undressed more- losing her bra- and is rubbing Adira's body to speed things up.

"This is good...but not enough. She'll just say that I'm not good at licking pussy."

Ivy rolls her eyes, but doesn't object.

She undresses fully and gets on her back.
Adira starts licking her pussy, while Dee goes behind her and does the same.

The young girl knows her stuff and actually makes Ivy cum!

In the afterglow, she watches her Stepdaughter cum from Dee's tongue.

"Maybe...maybe you were right," Ivy says, "Let's go again to see if you're right though."
She winks at Adira, who smiles back.

The young girl is back-first on the couch.
Ivy is licking her pussy.
