Get your mother involved

You don't need to give Sam any order. She lifts her skirt by herself to offer your mother a better view on her ass bouncing up and down as she impales herslef on your shaft. "Like what you see, bitch?" she asks, slapping both of her cheeks at once. "I wish Mom was sexually aroused when Sam calls her degrading names and wouldn't protest against it."

Your mother swallows her spit and nods frantically. "I love it, sweety." she answers in a dreamy tone.

You grin and place your hands just where your older sister spanked herself to firmly seize her butt, then spread it apart so the blond woman can admire her tiny hole.

"Then kiss it." the maid orders while softly caressing your neck and pressing your face into her cleavage.

Your mom's face turns red, but her face almost instantly disappears between her daughter's cheeks, and you soon start hearing a licking sound.

"I wish Sam's ass was extremely sensitive, to the point that a rimjob would give her as much pleasure as a cunilingus."

The beautiful brunette's scream double in intensity, as she gets her pussy and ass taken care of simultaneously in very different ways.

"Don't just kneel." you suddenly instruct your mom. "Crouch with your thighs spred and caress yourself. Knead those fat jigglers and finger your little cunt while you pleasure your own flesh."

The older woman gasps, but after a brief instant of hesitation she obeys to the letter. She soon starts whimpering, one hand squeezing her massive left tit, the other searching inside her panties. You can see it's not easy keeping her balance perched on her high heels.

"I wish Mom's nipples were as sensitive as her clitoris, and her entire chest was erogenous enough to bother her when she's wearing any piece of fabric over it."

The muffled sound rising from your sister's butt suddenly turned higher.
