She does indeed

"You're not really expecting me to wear that...? And what, do a film?" Nathalie is horrified.

Miss Wilson has put down her camera and is setting up the video recorders. The outline of her thong is still clearly visible through her grey dress.

"Don't worry," she says. "You can keep the mask on, and it isn't a speaking part. No one will know its you. But it would be such a shame to let that body of yours go to waste."

"Certainly would," grins Frank.

"Now put the costume on," Miss Wilson says. "Or I start publishing your photographs on the internet."

Grimacing, Nathalie steps into the red one-piece swimsuit and pulls it up, running her fingers along the elasticated leg bands to straighten them. The swimsuit is tight but somewhat better than being naked. She puts the black cloak around her shoulders and then the mask, which covers her face.

"Fantastic," says Miss Wilson, admiring Nathalie's body. "People always love a new model, and your body is just perfect. Ok, so your role in this movie is simple. You're an evil villainess who has been captured by Mighty Bat here, who is going to give you a little punishment spanking." She sees the look on Nathalie's face. "Don't worry, the market for this stuff doesn't do BDSM or nudity. Your costume will stay on and the spanking will be very light. You still need to kick and struggle though as if it is really hurting. It is a punishment, after all. Everything clear? Ready?"

"Ready," grins Frank. "I'm looking forward to spanking this posh bitch."

He sits down on the chair expectantly. Nathalie's eyes are drawn again to the bulge in his grey costume.

Soon I'll be pressed up against it, she thinks. Urgh!

"We're rolling."

Frank booms. "Your dark reign of crime is at an end! Now come take your punishment." He pats his thigh meaningfully.

Nathalie shuffles forward, face burning, feeling extremely thankful for the mask.

Frank pats his thigh again. "Over you go!"

Nathalie pauses, but has ****. She slowly lowers herself onto his lap, feeling the hardness of his erection pressing into her groin. He steadies her with one hand and expertly positions her ass with the other. Nathalie feels ridiculous, bent over and helpless, and she can tell Frank is silently laughing at her.

"Now you will find out that crime doesn't pay!"

She closes her eyes in anticipation.

There is a pause.

Smack!

"Ow!" Nathalie says, kicking her feet. Wasn't this supposed to be a light spanking?

Smack! Smack!

"Ow! Hey! That hurts!"

Smack! Smack!

The spanks come expertly fast and hard on her poor ass, and soon Nathalie is writhing and dancing on Frank's lap. In doing so she knows she is grinding against his erection and that he is enjoying it. After ten minutes the spanking stops, and she becomes aware of Miss Wilson moving in for a close-up.

"You've taken your punishment like a little girl, not a crime lord! Lets see your face!"

And then Frank unmasks her.

"What? No! You said...." Nathalie struggles on his lap but he holds her firmly in place. Miss Wilson thrusts the video camera into Nathalie's blushing face.

"And... Cut." Miss Wilson says. Frank immediately lets go of Nathalie and she slips to the floor, then gets to her feet and paces with one hand on her poor pink ass, much to their amusement.

"Don't worry," says Miss Wilson smugly. "That final shot won't go out. Not unless you start shooting your mouth off. If you do, you're going to become an internet star. Do we understand each other?"

Nathalie, blushing at the thought, nods.

"So your plans to **** me have failed, Miss Chapman. Think about that next time you sit down. Now get dressed and get out of my house - and if I ever see you again there will be hell to pay. Understood?"

Nathalie nods again, sullenly, and then starts getting changed back into her dress and blouse. I'll get my ****, she thinks, casting an eye at her former teacher. One day. I'll see you're the one being an internet star. I swear it.

Dressed, watched closely by her tormentors, she slips out of the room and prepares to leave the house.

"Oh, by the way," says Frank calls after her. "Nice ass for a posh girl!"

Dirty bastard! She flushes and steps out into the street. The sounds of laughter behind her cut off only when the door shuts.

How humiliating, she thinks. At least she has Miss Wilson's g-string tucked into her skirt. She's halfway to winning the bet.
