Five minutes after Michelle had had her bottom spanked again there was a knock on the door.

She froze in terror, looking at me with pleading eyes.

“Well don’t just stand there!” I commanded. “Go and answer the door!”

Still she didn’t move. “But, but…” she stammered. “I can’t let anyone see me like, um, this…”

“Of course you can!” I laughed. “It’ll be Sally, and she knows all about you, Michelle. Now be a good girl and run along and let her in.”

Sally is my sister. She’s three years younger than me, and I know Mike had always had a bit of a thing about her. He’d once confided in me that it would be a dream of his to make a threesome with us. She was the only person I’d confided in about Mike’s desires to be dressed as a female, and she’d helped me decide upon how I should deal with it. I knew she was SO excited about seeing him en femme.

My explanation didn’t help convince Michelle at all, but the threat of me going to answer the door and then cane her bottom was enough to make her obey.

She tottered over to the door and peered through the lens to see who was there. Sure enough, it was Sally. Reluctantly, she opened the door to her.

Sally stepped in, looking Michelle up and down. “My, my!” she said. “You do make a pretty maid, don’t you, Michelle?”

Michelle blushed the deepest shade of red, before closing the door.

Sally came over to me and we gave each other a peck on the cheek. I could see Michelle watching us, wondering what was going to happen next. I knew that even us giving each other a peck on the cheek would make his imagination run wild.

Sally sat down on the sofa and crossed her long legs.

Michelle was frozen to the spot, and it was only my command that snapped him out of it.

“Come on, girl, how long do you expect our guest to wait for a drink? Or do you need me to spank your bottom again to remind you of your place?”

I didn’t think Michelle could blush any deeper, but I was wrong.

She scuttled off to the kitchen to get Sally a G&T.

When she brought it out and handed it to Sally, Sally thanked him, and then complimented him on his pretty dress, stockings, and high heels. Poor Michelle just looked mortified.

I ordered her to fetch the canapes she’d put in the oven.

Sally turned to me and said “Michelle looks very cute in her dress, stockings and high heels, Sis. Did you put her into panties as well?” Michelle returned with a tray of canapes to serve us just as we were discussing her underwear.

I laughed. “Of course I did! Michelle! Turn around and let Sally lift your dress to see your frillies!”

Michelle looked utterly humiliated, but she knew she had no choice.

As she presented me with the canapes Sally lifted the back of Michelle’s dress to reveal her frilly panties.

“Oh! How sweet!” she laughed.
