I have always enjoyed paddling a woman wearing jeans. Sure paddling panties and bare bottoms are most enjoyable, but I like jeans for a change. The crack the paddle makes on jeans is louder.

Looks Like She Found The Perfect Fit
Bacall got new jeans. We are breaking them in.
Our Bottoms Burn 
Soften the sound, tightens the bottom, my wife dreads these spankings. I still enjoy a good old fashion OTK bare bottom for her.
i can't say i've ever been spanked over jeans. I'll ask bikss what he thinks!
I've always found that spanking over well fitted jeans has a tendency to hold the heat in! Hope you and Bacall have fun breaking in those jeans. 😉

It is pleasant warm feeling.
Short shorts are ideal as, when taken over her disciplinarian’s knee, she is immediately aware that a lot of her lower buttocks are already conveniently bare for me. I can add to her humiliation by further hoisting them high into her butt crack.
