and with cropping the photo
Had she worn a thong the day before? Unlikely, as the color on the sides beyond the bathing suit seem okay, and not in any way slightly red, but also the red seems to extend a bit below the cheek, as if the back of the legs were also spanked some of the time.
Just another reason to go to the beach, but to wear suntan lotion. Unfortunately I did not see this woman and her friend walk back past us, but I did not really think to watch for her.
so, if winter ever gets you down...
