Why does she look so unhappy? A bikini car wash makes more sense...
It was probably hot the day that picture was taken. I had a neighbor who used to have his wife mow the grass while he edged and trimmed the shrubs, and then he’d pick up all the trimmings.
When they were done on a summer day, he was washing himself with a hose. She came and let him spray her down. He *UN*politely put the hose in her shirt - she seldom wore a bra at that. Wet “TEE shirt” time!
