One hot Saturday, there was a knock at my door. I answered it, and there were my neighbour's children, Jason and Lucy.
"Hi Tim," said Jason. "Could we have a swim in your pool, please?"
"Sure thing," I said. "Go right ahead."
I had only moved into that house a couple of months ago, and my next-door neighbours were the only people that I had really come to know. Jason was eleven, and Lucy was nine. Their mother was Kim, and their father was Roger. Roger was a sales rep, and he was away a lot. So I often helped out by looking after Jason and Lucy when Kim had to go out. They were well-behaved children, and I was happy to look after them. As they didn't have a pool, my pool was very popular with them.
I settled into a sun lounge, with a drink, to keep watch over Jason and Lucy. Then after a while, I saw Kim's head appear over the fence. "Hello Tim," she said. "Thanks for letting the kids swim. But just send them home if they are a nuisance."
"They're fine," I said. Then I had a brilliant idea. "It's so hot. Why don't you come and have a swim with them?"
"Thank you, I will," said Kim. "Be over in five."
A few minutes later, Kim arrived. "Roger on the road?" I asked.
"He should be back tonight," she said.
Kim was wearing a short housecoat, which she took off. Under the coat she was wearing a fairly modest two-piece swimsuit. I had never seen Kim in summer clothes before, and I was pleasantly surprised by her figure.
Kim dived into the water and swam around for a bit. Then she stood up and said, "Aren't you coming in? It's lovely."
The water had worked it's magic on Kim's suit, and her nipples were clearly visible under her top. I wondered if her pussy was on show as well. This was too good an invitation to waste, so I peeled off my shirt and dived into the pool.
Of course, Jason and Lucy immediately attacked us. As we were fighting them off, I accidentally rubbed against Kim's hip. She didn't make any attempt to move away, in fact, she smiled at me and rubbed her hip against me. Very interesting, I thought.
