I was helping my wife strip the bed - it was time to change the sheets... and as I tugged the fitted sheet off the mattress a purple lacy thong popped outta the crack between the mattress and the footboard.

I picked it up and looked at it. There was a bit white shmutz in the crotch. I held it up with two hands. They were tiny - way too small to be my wife's. I can't remember the last time my wife wore a thong, but it was at least two decades ago.

"Whose are these?" I said.

My wife turned, said, "Oh!" Then she laughed, "Well... they're not mine."

I tossed them at her, "Whose are they then?"

Daisy said, "They're either Nicki's or Phoebi's." She sniffed the thong, "They're Phoebi's, I think."

"You have a sleepover while I was away?" I asked.

My wife shrugged coyly, "Girl's entitled to her secrets."
