Well, I did punish Sylvie in a new way, drawing upon some of the ideas above.
She had clients coming into her office the other day, so I made sure I arrived before they did. Sylvie knew she had a punishment coming, but not where or when it would be administered.
A couple of minutes before the clients were due, I called Sylvie into the small supply room off of her office. After she undressed, I made her bend over the small metal file cabinet that was in there, and she had to stay there until we heard the clients arrive. I didn't gag her or anything, and she can be very vocal! Once the clients were sitting quietly in the waiting room, I caned her, concentrating on the top of her thighs. She couldn't cry out as I caned her, because of the clients in the next room.
As soon as I finished, I made her get up and dress right away; no waiting/recovery period. As soon as I told her to get dressed, I went and showed the clients into her office, so she had no time to even think about anything other than getting back to her desk right away.
I looked into her office once or twice while she was talking to them; it was amusing to watch her trying not to sit down anywhere! She leaned against her desk for a while, but even that was uncomfortable!
If I had been thinking ahead, I would have pinned her labia lips open, stimulated her to flowing wetness, and made her talk to them with no underwear on, too. Oh, well, next time ....
I also found a new position for punishment. I made her lay on her bed, flat on her back. Then she had to pull her legs up til they were almost touching her chest. She held them with her hands until I got cuffs on her ankles, which I attached to the headboard with bungie cords. I put 2 pillows under her lower back/bum to give her a little support - she's no spring chicken anymore!
So her legs are spread eagled over her head, and her arms are now flat on the bed by her side. I cuffed them, and bungied them to the footboard. Then, I flogged her until my arms got tiredWhen I was finished, I dripped candle wax onto her thighs. I wanted to get one of those small tea light candles, and set it on her pussy, but I wasn't sure how hot the metal around them got, so that will have to wait. Instead, I pushed a long white taper into her, and lit that.
I also would have loved to make her beg for an enema while in that position, but since her stomach was already scrunched up under her legs, I decided that might be too awkward for her, and a bit unfair. Oh well, we enjoyed ourselves anyhow ...
