This happened to me recently. Firstly no one other friends or family know about my meesy kinks.
Recently while having friends round for dinner a topic of conversation came up that was who is the most dominant person in a relationship. Naturally I said she was, fellas we know it's true really.
The other Cople who were with us he started taking the piss out of me for saying that what my misses says goes... a little banter each way about it and my.missus said... I'll show who's in charge.. So without any warning or anything my misses told to go sit on a chair near the back door... naturally I did..the other couple and my misses came out side. She said to them just watch...she ordered me to undo two buttons on my shirt, well at this moment I figured out I something was about to happen. I said no several times because I was really really embarrassed at the thought of being messy in front of friends.. she just said either open your shirt or I'll cut it open... I'm wearing the Xmas gift from her a 150 hugo boss shirt... I said again not to do anything because I loved the shirt. ..again she made her threats about cutting it..I held my ground in believe she was only showing off.. she wasn't. ..seconds later she cut down the front of my shirt.. only about 10 cm. .but it was now cut... I was gobsmacked. ..then she dumped a carton of custard down my front saying. ..I did ask you to open it so it wasn't her fault...both my friends were laughing their head off at the situation. There was me sat in a patio chair with a 150 shirt cut and soggy with custard. By the time I was allowed to move it had run into my pants and jeans.
On one hand I was embarrassed to hell by what she'd done... then she said I had to not move for 15 minutes. .by this time the custard had made its was into my jeans etc..on then was I allowed to go get cleaned up, the other couple really laughed loads at me in agreement that she was in charge in our house... a fact I'd agreed to but it was her way of proving a point. I seriously never expected her to anything like that. So spontaneous in front of others,not bothered about my embarrassment at all.
Never been so embarrassed and humiliated, while at the same time... quietly very turned on

God I love my misses and it was a beautiful soft touch sheen shirt..now in the bin.
