A new thrill... (image story in the description)

As she treaded water near the edge of the pool, she was filled with excitement about the new thrill she was experiencing. She had been thinking about this for weeks while she was away, planning what jeans she would wear, picking out a new sweater, choosing which boots and planning when the opportunity would be right. The water needed to be warm, yet the weather cool enough for her to dress like she wanted. And today was the day, she had snuck out to the pool, sat down and stuck her feet in then slid into the water before she could change her mind. She loved how everything felt now that she was in the water. This was quite a different feeling of excitement with the chance of being caught. Normally she would have striped and gone in topless in just her underwear, but this time the naughty feeling of wearing all her clothes was a delightful new experience which wouldn't end when she got out because she would be wet for hours!
