I see the two girls down there in the burnt out warehouse. They must be 18 or 19. Fresh-faced but worldly wise. One tall and dark-haired, the other blonde and tanned. I watch them through a dusty shattered window. I make a pretence of hiding but they know I’m here. They like to be watched.

Their game is wild. I know it’s a game because when they first stumble drunk through the doorway, they are laughing and holding hands. They kiss softly, cheerfully caressing each other through their skimpy summer clothing. They are equal partners at this point - they have not yet taken on their special roles.

The girls French kiss each other - exploring with their tongues, hands stroking over thighs and buttocks, eyes sparkling in the sun.

The blonde looks at me and laughs, drunkenly. She can only see my face through the glass but she must realise I have my cock in my hand by now.

The dark-haired girl leans close in to her ear and whispers something nasty. The blonde laughs, apparently shocked and excited by her lover’s words. She nods enthusiastically and immediately drops to her knees - assuming a submissive role down there in the dust.

This is where their game begins - the tall Mistress punishing and humiliating her worthless blonde Slave.

“Strip for me, Cunt!” snarls the Mistress.

I am startled by the words - shocked by the way the dark-haired tormentor’s lip curls up into a cruel smile.

The girl on her knees appears unfazed. She has played this game before. It obviously excites her. She wants to be treated like dirt.

“Do it, bitch! I’m waiting.”

The blonde nods and begins slowly unfastening her dress.

“Quickly! I’ve not got all day. Do you think I want to spend my time with a worthless whore like you? Hmn?”

“No, Marianne.” The Slave lowers her eyes.

“What was that?” The Mistress grips a clump of the girl’s hair in her fist and draws her head right back. “What did you call me, Cunt? Who the fuck is Marianne?”

The Slave blinks up at her Mistress, her cheeks flushed, her lips moist. “Sorry.”

The dark-haired tormenter shoves her Slave back onto the hard, wooden floor. “I am your owner. You call me “Mistress,” nothing else. I call you “Cunt,” or whatever the fuck I want to call you. Do you hear that, you wretched little slut?”

The blonde girl pants, excitedly. “Yes, Mistress.”

“Good. Now, take that fucking dress off before I thrash you!”

The Slave nods and hurriedly slips out of her dress. Her small, pert breasts are flushed from her arousal. The nipples jut out thick and hard. She lies there in the dust - vulnerable and naked, but for her panties.

“Open your legs, Cunt!”

The girl parts her thighs.

“Wider!” The dark-haired Mistress grabs the blonde’s knees and thrusts them apart.

Her Slave gasps and writhes on the wooden floor.

Marianne frowns and points a finger at the damp gusset. “What the fuck is that? They’re soaking wet, you filthy whore. Have you pissed yourself?”

“No Mistress. I’m ... I ... you excited me.”

“Don’t fucking lie to me, Cunt! You pissed your panties. They’re a filthy mess now. Aren’t they?”

The Slave nods slowly. “Yes.”

“What do you do to a dog when it messes on the carpet?”

“Don’t know.”

“You shove its nose in it so it learns not to do it again. Don’t you?”

“Yes, Mistress.”

“Well I’m going to teach YOU a lesson, Cunt.” She immediately hikes the short skirt up around her waist, revealing her bare crotch. Black hairs curl wildly around her vulva. In the center, the pink lips glisten. The Mistress is as aroused by the game as her Slave.
