I experienced the following interaction when I was staying with Uncle Frank and Aunt Eleanor for several weeks...
Aunt Eleanor caught my cousin (Amy) and I stealing some pocket change out of Uncle Frank's big "change jar" (we wanted to purchase ice cream sundaes at the dime store, instead of just a few pieces of candy).
She said, "Amy, your father will deal with this when he gets home! And, Johnny, you can expect your Uncle to deal with you also! Both of you, go cut and prepare switches from the apple tree! Then, instead of going to the dime store this afternoon, you will pull weeds in the vegetable and flower gardens, until it is time for your thrashings!"
When Uncle Frank arrived home, he came to the vegetable garden and said, "The two of you will be going to bed without dinner tonight, so eat some raw vegetables right now, if you're hungry. Then, prepare for bed, but don't put on your pajamas after showering. You can bring your swiches to the family room."
Apparently, when strict discipline was called for, this was standard operating spanking procedure for Amy... to fetch an apple switch and come to the family room after her bedtime shower (still naked).
Amy said, "Please Sir, don't have us be naked in front of each other!"
Uncle Frank said, "First of all, you and Johnny are cousins and you were partners in committing your crime, so you will also be partners in receiving your punishments together. Secondly, there is NO reason for me to punish your INNOCENT blue jeans, your INNOCENT panties/underpants, or your INNOCENT pajamas, because they did not try to steal my money! The two of you are guilty, and your BARE bottoms will receive the stripes that you deserve, not some innocent fabric that would protect you from your consequences!"
Amy and I were both developing tweenagers (approximately 12.y.o.), so coming to the family room naked together was quite embarrassing!
Amy received her punishment first, and my penis jumped to attention while watching her bend herself over the back of the spanking chair, and seeing angry crimson stripes/welts being raised across her bare buttocks, as her tears started to flow.
Although it was very embarrassing at the time, receiving our discipline together turned out to be something of a bonding experience for us. Approximately 50 years later, we still chuckle when we reminisce regarding our shared naked punishments experience. The best part of sharing this story is quoting the different phrases that Aunt Eleanor and Uncle Frank used when instructing and scolding us. A few years ago, we both admitted to each other that recalling Uncle Frank's discipline (specifically, presenting ourslves and seeing each other in-the-nude together) has been a source of sexual arousal for both of us over the years, and she told me that her husband sometimes role-plays scenes in which she is punished, "Uncle Frank style". She asked if my wife would be interested to play the part of Aunt Eleanor, so Amy and I could both experience Uncle Frank's discipline, together again.
My wife was very agreeable, and it was definitely a turn-on to hear "Aunt Eleanor" tell us to "fetch switches", and that "Uncle Frank" would "deal with us". And, to hear "Uncle Frank" tell us to take showers, and then report to the family room, naked. And, to hear "Uncle Frank" refuse Amy's request to not be punished together, in-the-nude. And, to hear his explanation that the bare bottoms of naughty boys and girls deserve painful thrashings, NOT the innocent panties/pajamas/etc that would proide layers of protetion from the deseved conseqences... LOL.
Amy's husband did an excellent job of playing the part of Uncle Frank. Amy received her thrashing first, and my penis jumped to attention right on cue, as she was bent over the back of the spanking chair. The angry crimson stripes acoss her ass were very real, as were her tears. The only difference was that "Aunt Eleanor" (my wife) did the honors of thrashing my ass (and, spanking my "naughty erect penis" with a ruler).
