It was a story about a couple where Dad's hours were later than Mom's, so Mom was already ready for work and leaving while Dad was just getting into the shower when babysitter would arrive to watch baby for the day. Dad wasn't comfy with young (18/19) babysitter walking in on him in the shower, where babysitter made it clear she was going to do so anyway, and even wound up bringing a friend in to meet him naked when she was going to be taking over.
I just can't seem to find that story again. I think it was in either exhibitionist or non-consent/reluctance.
