Tiffany walks in none the wiser

Tiffany is quite the cutie, you think to yourself. Huge boos for her age and beautiful blonde hair. As she passes by. You see her phone playing a video of herself doing a TikTok dance. She looks still at her phone and sits down on the couch, not even looking at you. Probably some stuck-up popular bitch.

You use this time to look on your computer for some nice hippo bimbo porn for your apprentice fellatrix to hear while you talk with her daughter. You play a couple of videos at the same time and crank up the volume to make sure nothing distracts Sarah from her training.
"GLUUUURK!!!!!" You feel a nice, tight constriction around your member. Sarah had a bit of a ****, nothing unusual in a throater's training. Tiffany looks up from her phone in a startle. *cof cof * you fake to disguise the sound "Sorry for that, I have been coffin all day, nothing nice to see you again, Tiffany, how has the week been going?"

"OO you know, same hold, same hold ... My tiktok's as not been getting any more views, my boyfriend Dilan keeps begging me for sex. But mainly, my Mom has been pissing me off so much. All she does is complain that I am always on my phone. That I should study. "You can sympathise with her as you also were not the biggest fan of school and spent most of your time online. "Why should I study??? That's not how you make money nowadays, plus she is just a dumb bitch who married my rich loser dad, so she does not know anything about working hard. I wish I could make money online."

She speaks in this really bratty tone. That would normally piss you off and make you slap and fuck the shit out of her face, but you really care this time.

"GLUUUURK!!!GLURK!!GUGDD!!"
...
"What was that?"

"Nothing," you say in a panic, quickly getting a hold of her mother's hair by the back of her head and sinking the rest of her head along your shaft, muffling her chokes.

...
While the silence fills the room, you keep your cock deep in your dumb bimbo shaped cock holster, and as she struggles, the sound is almost imperceptible. But you should still make an excuse.

"Sorry, I had a video playing on my computer."

Looking under your desk, making sure Sarah is not listening, but she is fatefully at work, sloping and polishing your gnob. She feels nice, not quite taking you all the way down her throat now, but in the deep concentration that you expect from her. Right now, she is living in a world of void where only your cock and her mouth exist, with a voice telling her that her "This is your destiny, you were born to be a slut."

Tiffany looks clearly uncomfortable.

"It sounded like somebody ****.... "
"I can kinda still hear it,"
...
"Are you watching porn ?"

You think for a bit, taken aback by the question of the nubile innocent teen, and decide its propably still not the right time to show her mother as your blowjob trainee, she is still clearly embarrassed about sex, and you imagine she would not be able to grasp her mother's state of mind of absolute submission.
But why not teach her, slowly?

"Why do you think that?" you ask, keeping your best poker face and looking back straight into Typhany 's blue eyes, while getting satisfaction from her mother ever improving tecnique. "You told me you spend a lot of time online. Do YOU watch a lot of porn?" you throw her question back at her without answering "You said you wanted to make money online."
