Yes, she does.

"Make out with her Carol." You command the maid. "Dominate her tongue."

"Yes, Master." Carol replied immediately, crawling seductively towards your bound mother.

You take your finger out of your mom's cunt, placing it between your lips, sucking on your mother's juices.

"Huh... It's a little sweet..." You whisper. You could grow used to that taste.

"You'll get it, mom. Your fantasies..." You say, your lips leaning closer to her cunt. "Will come true..."

You and Carol both reach her at the same time. Carol kissing her lips agressively and dominating her tongue. You, tasting her pussy on your lips, licking her slit.

"Mmmmmmph!!" Katherine cries out, bucking her hips, her orgasm approaching rapidly.

You look up, watching as Carol devours her mouth, making her moans in pleasure. You lick her slit, slurping the juices off your lips.

Your teasing from before had left her agitated enough, so it's no surprise that your mom was close to an orgasm already.

"Haahh..." And so, soon enough she released a loud moan, her eyes rolling back into her head. "Aaaaannngh!"

Her whole body trembling as she climaxed, her thighs clamped down on your head, locking it in place.

You don't care though, your tongue kept circling around her clit until she went limp, panting heavily.

"Very good..." You compliment Carol after she finished wiping away her saliva. "Now... Let's turn her into a real slave."
