Down her fucking throat

"Im gonna fucking cum soon" You shout as you put both your hands on the wall and start skullfucking her into it, your balls slap against her chin as she senselessly rolls her eyes back.

"Yeah stay there like that you brat, this should teach you your place" you exclaim as you near orgasm, your cum building its way up to the shaft

You let out a "F-F-FFFFUUUUHHUUHHCKKKK" as one final thrust sends 5 or 6 loads of cum straight down her gullet.

She swallows every single drop of your hot cum and licks her lips.

After holding your cock there for a bit you pull out and collapse onto the shelf next to you as Mia start to recover. "Your gonna be my cumslut from now on, whenever or wherever I tell you" you assert.

"Yes master" she says, a hint of smug in her facial expression like she was hoping that would happen.

You go back outside and leave her to clean up
