I lead him though to my classroom and told him to sit at the desk. I almost felt sorry for him – he was so self-conscious wearing his little schoolgirl uniform, and being so desperate not to expose his frilly knickers.

“You are to sit here while I bring someone in to meet you. Won’t it be nice to have another girl here in your classroom?” I asked, mockingly.

I knew he was already beaten. Everything from now on was a bonus.

“Naomi!” I called, “Would you mind joining us?”

The door opened and Naomi came in. ‘Naomi’ was actually Sarah, my younger sister. She was tall, slim and blonde, and turned heads wherever she went. She was wearing an older girl’s version of the school uniform Mike was wearing. I could see Mike’s jaw drop when she walked in. In other circumstances I’m sure he would have been completely smitten by her. But in his current predicament he just blushed beet red at being seen dressed as a little schoolgirl by such a gorgeous creature.

“Oh my!” exclaimed Naomi. “Who’s this little darling?”

Mike sat there frozen. “Well introduce yourself! Don’t be rude!” I ordered.

“I’m, um, uh…”

I brought the spanking paddle down hard across his knuckles. “Stand up, girl, when you're addressing your betters. Did your mother not teach you any manners?”

He awkwardly stood up and continued. “I’m um, Mike.”

“Well hello Um Mike. How nice to meet you. But I don’t think we can call you Um Mike when you're dressed in your pretty little schoolgirl uniform, can we? I think we’ll call you ‘Michelle’. Do you like that name?”

Poor Mike hung his head in shame and embarrassment.

“Well, Michelle,” I taunted, “do you like your new name? Or do you need another spanking to help you decide?”

“Yes, Miss.” he stammered.

“Yes Miss what?” I was determined not to make things easy for him.

“Yes Miss. I like my new name, Michelle.”

Acceptance of his new status was an important part of his therapy, and I was delighted at how well it was going.

“You look so sweet in your uniform, Michelle!” teased Naomi. “Are you wearing panties under your little dress?”

His face was almost impossibly red, and he didn’t know what to do with himself at this humiliating questioning.

I brought the spanking paddle down hard across the backs of his thighs. “As it seems the cat has got your tongue I think it’s best if you show Naomi what you have on under your dress. Lift it up so that she can see.”

He looked at me pleadingly, silently begging me not to inflict this further humiliation. I just stared back at him, tapping my fingers against my arm, clearly signalling that I was waiting for him to comply. Naomi had her arms folded, a smirk appearing across her ruby red lips.

Slowly, reluctantly, he lifted the front of his dress, revealing his frilly white knickers.

“Oh my God!” exclaimed Naomi. “I’m sure I had a pair of knickers like that when I was maybe three. They’re so sweet. Let me see the back!”

She went round behind the poor dear and lifted up the back of his dress, revealing the layers of lacy frills across his bottom. She teasingly ran her hand across his pantied bottom. “Mmmmm… so soft and silky. They must feel SO nice against your bottom! And so delicate too. Almost no protection at all when you earn another spanking!”

For brief moment the look on Michelle’s face made me wonder if he’d already suffered enough. But then I remembered the awful things he'd done, and I pressed on with the rest of his therapy.

“You can lower your dress now, Michelle, and sit back at your desk” I said. “You’re now going to do a test. It’s about some of the women who’ve done amazing things. The answers will be easy for anyone who recognises the power of women. You need to get at least eight out of ten right. If you do, you will earn a reward. If you don’t then you will earn another spanking. Is that clear?”

He meekly nodded.
