So ... after I spanked her in the nude, I made her put her jeans back on and spanked her over her jeans.
The sequence was:
Over jeans
Over panties
Bare bottom
Nude
...and then over jeans ... I know this isn't usual!
But I didn't want to do too much skin damage, and the jeans protected her, so I could spank her longer.
Partway through this spanking, you can hear her yell, "not there!" That's when she reached back to cover her butt, and I spanked her thighs. That educated her about the error of trying to cover up.
What a cute photo!
