Eventually

"I...I...can't...I'm not a...a slut...I'm a...a good girl..." she whimpers.

"Then you can't be a special student," you say coldly, letting go of her and stepping out of the shower, grabbing a towel and starting to dry yourself. She gives a whimpering sob and starts to cry softly.

"Please...I want to...want to be special...and I want to be good....please...there must be....be some other way."

"No other way. Finish your shower. Dry yourself. Put your clothes on. And leave," your voice is flat and uncaring as you step towards the bathroom door. You have your hand on the knob when she gives a guttural wail.

"Noooooooooo! Nooooooo! I'm begging you! Begging! Please...I'm your slut....your whore...Please....fuck my slutty ass...Please...Oh God Please...Don't leave me....I want to be special!....Please....Please Sir! Please fuck my ass...I want it...I want it..."

You step back into the shower and see Faith with her palms pressed against the wall, her legs spread as wide as the tub allows, her back arched and her ass raised in offer to you.

"That's a special little student," you tell her as you grab her hips and pull her closer, your cock hard, rampant and eager.

"Go slow, oh please go slow...." she whimpers.

"Be a good girl," you say reassuringly as you press your rampant cock against her soap lathered rosebud. "A very good girl."

"Ohhh...Oh God! Oh! Oh! Oh! Oh God!" she squeaks as the tip of your prick presses into her. She slaps at the wall, looking back over her shoulder as she stands on her toes and raises her ass.

"That's a good girl," you praise her, gripping her hips and pressing deeper, starting to fill her bowels with your thick shaft.

"Oh! Uh! Uh! Uhn! Oh! Unh! Oh God! Oh God I'm a Good Girl! A Good Girl! Oh God! Yes! Oh! A Good Girl! Oh Fuck! You're so big! You're going to split me in half! Oh! Oh!"

"Yes! Oh Fuck Yes!" you growl as you start to thrust into her with long deep strokes, her tight ass gripping your throbbing cock. Faith starts to buck and convulse, slapping at the tile wailing with blissful joy as she starts to come, arching her back and grinding herself back against you.

"Oh Fuck! Fuck My Slutty Ass! Oh Fuck Let Me Be Your Whore! Your Slut! Your Gutter Whore! Take Me! Take Me! Take Me!" she screams in orgasmic joy, all signs of the shy and timid student gone, replaced by this desperate, wanton trollop. With a fierce growl you pound her hard, filling her ass with meat, exploding inside her and filling her guts with hot cream.
