Make her copy a pornstar.

"Considering how you have forgotten our lessons we had better start with an easy one", you say to the attentive popstar. "I will put up a video of a professional cocksucker and all you have to do is copy everything she does".

"OK", Katy replied. "Could we turn up the heating it is quite cold in here", she asks.

You reach down and tug on one of her erect nipples. "No I think I like seeing these standing on end." You say.

You turn on your television and turn onto the video. You have chosen one of your favourite porn videos, a facefuck of a very talented whore who barely flinches at the rough usage.

The video starts and Katy copies as she was told, massaging her big tits and rubbing her pussy through the solo section of the video. Your cock aches watching her copy the whore's every move. Impatience strikes and you fast forward the video. Katy is taken aback as the same well made up girl she was copying is now on her knees, covered in her own spit and her throat bulging with every deep penetration into her throat.

Katy looks up at you, and pauses.

"Do it", you command.

Katy obliges, opening her mouth and taking your cock into her warm wet hole. You look down and can't believe what you are seeing, Katy's big tits bouncing every time she slides her head back and forth on your shaft. You let out a satisfied groan.

Katy sits back, "See I am good at this", she says smirking. You worry about the change in attitude and land a firm slap around her face.

"My dick is only half wet", you shout. "Do that badly with a producer and your next album will be scrapped. Maybe that is what you want?" You ask.

Katy quickly moves from holding her stinging cheek to focusing all her attention on your cock and presses her head into you as hard as she can, forcing your shaft into her throat. She gags, but perseveres, saliva dripping from around your cock into her big tits.

"Best make you look the part", you say. Rubbing your sodden cock all over her face. Her heavy make up smears all over, leaving her a mess. You **** your cock back in before she has had time to catch her breath, taking hold of the back of her head and watching her lips inch closer to the base of your shaft.

"Nearly there", you say, pushing harder, feeling her gag constantly at the deep penetration. You finally reach the base of your cock, feeling her throat squeezing tightly around your head.

Katy taps on your legs, telling you to pull out.

"She isn't doing that" you say, pointing to the screen. The girl on screen has a cock held balls deep in her throat and is simply holding her heels.

You can only tell that Katy can even see the screen because she relents her protesting, taking hold of her heels on the floor behind her back, accepting your control.

You bucket your hips, staying deep inside the popstar and enjoying the gagging around your cock. You can feel an orgasm bubbling up, and good timing too as Katy's eyes are about to roll back.

You pull your shaft free, holding Katy's weak body by her hair, and covering her already messy face with rope after rope of thick cum. Katy slumps to the floor once you have let go, trying to get some air, she looks at the screen to see an almost mirror image of the pornstar on screen, and smiles.
