He'll take matters into his own hands... literally

"It looks like I'll have to administer some real punishment myself."

Anna was a bit worried with how frustrated the teacher was getting.

He sat down in a chair in front of the class and beckoned for Anna to approach him. "I don't know what you were thinking, but this punishment will make you think twice before you try to pull a stunt like this again." He motioned for Anna to lie down on his lap. When she didn't respond, the teacher told her, "Anna, you'd better obey if you plan on passing this course. Following instructions is a large portion of my grading."

Anna hesitated, but eventually complied. She lay face towards the ground on his legs. Mr. Barclay's bony legs dug into Anna's midriff. Her face glowed a bright shade of red as the teacher grabbed the hem of her skirt and slowly pulled it up. The rough cotton of Anna's skirt brushed the outside of her thighs as it exposed her legs. As the same sensation passed over her soft rear end, Anna stared into the floor. A cool draft tickled her bare butt, but it was the audience of her classmates that sent shivers down her spine.

Caught up in her embarrassment, Anna did not prepare herself for the callused hand smacking into her smooth skin. The loud clap echoed through the room. First startled by the noise, Anna gasped and then clenched in pain. A bright red hand print slowly faded from her unprotected ass.

Once again, Mr. Barclay's hand sliced through the air, bringing another bright red hand print along with it. While more prepared this time, Anna still felt the slap shake her whole body.

The teacher's hand came down hard again, not yet satisfied with the pain it had inflicted. Anna counted the spankings in her head, "3... 4... 5..." She could feel each slap fly through her body, "6... 7... 8... 9..." Anna waited for a tenth slap, desperately hoping it would be the last.

She heard the sound of air whipping around the teacher's hand as it left her backside glowing with heat. Anna balled up her fists, clenching her fists and clenching her teeth to stop herself from exclaiming profanities.

Anna held her stance, waiting to see if there would be more slaps, but none came. Relieved to be done with her punishment, She relaxed her whole body. Each finger uncurled slowly and opened her eyes. She let out a long sigh, which is the only reason she couldn't cry out when Mr. Barclay's unrelenting hand imparted her with one last smack. She squirmed while her relaxed butt shook with the impact.

The end of the punishment had startled Anna so much, she lost her balance and rolled onto the floor without the teacher holding her down. Landing on her rear end, Anna balled up in pain, holding her mouth shut while she muttered obscenities.

Mr. Barclay dismissed the class and Anna picked up herself up from the floor. As the class and teacher left the room, Beth approached the red-bottomed girl.

"I guess I lost the bet then. If you want you can rat me out, after all, that was the deal."
