Kaye and I were finishing loading the car. It was still dark out but we had a very the long drive to the beach and we wanted to arrive by lunch and get a jump on traffic. We had rented a house just off the beach with another family. We were going with another couple that had kids about the same age as ours. The kids had been counting down the days.
We finished loading up the car and got on the road. The kids dozed off and Kaye and I looked at each other and smiled. Ever since the massage I got for my wife, we had seemed closer than ever. Her sudden, unexpected exhibitionism that night had turned us both on and the sex and been hotter and more frequent since. Somewhat surprisingly to me however, that night didn't light an exhibitionist fire inside of her. She had returned to her usual somewhat conservative self around other people.
We arrived at the beach right around lunch time. The house would be ready for a few more hours so we decided to get some lunch and then head to the beach. After eating we changed into our bathing suits at a public restroom and headed out to the beach. Kaye looked fantastic in her new bikini. Even after passing 40, her slender five three body and B cups were turning heads as we walked onto the beach. We settled in for some relaxation as the kids hit the water.
After we had been on the beach for less than an hour, Mark and Sue arrived with their kids. The kids took off for the water as the adults crashed into their chairs. Sue looked great. She, like my wife was also over forty but worked out regularly and was in great shape. She was about five foot five with shoulder length brown hair and perky A cup boobs. They were the hottest moms on the beach.
Once it got late enough, we packed up and headed for the house to get settled in for the week. The house was three stories with the main living area and one bedroom (ours) on the third floor. The ground floor had the playroom with a pool table, video games and TV. It was kid land. The second floor had the other three bedrooms.
That first night everyone had a late dinner and turned in early after a long day. My wife and I awoke around eight and quietly made love before leaving the room for breakfast.
Everyone had breakfast and began what would be the pattern for the week, heading to the beach for the day and then back for dinner and relaxation. The wives wore bikinis every day. Often at breakfast Kaye would be wearing her night shirt with no bra, her bouncing boobs and pointy nips quite evident. This was the closest she had come to being an exhibitionist.
Sue was a runner and got up every morning for a run on the beach. As we were eating breakfast she would come in all sweaty wearing her tight shorts and sports bra. Her nipples would be protruding. She looked great and I needed to make a conscience effort not to stare.
On the fourth night, we were hanging out in the living room drinking and talking. It was starting to get late and the kids had quieted down. Sue decided to clean some stuff up. She was wearing a loose tank top and as she bent over in front of Mark and me, her tits were on full display. We could see both of them all the way to the nipple.
Mark jokingly said, "Sue, did you decide to put on a show tonight?" She didn't know what Mark was talking about. Kaye, who was behind Sue, looked confused. I kept my mouth shut then Mark said, "You just showed us your tits." Kaye and Sue each had a shocked look on their face.
Sue with a look of disbelief said, "Really?" and then a devilish smile formed on her lips and she said, "O well." She shrugged and took the dishes into the kitchen.
When she walked back in, Mark was kind of laughing and "So you think it's OK that Jim saw your tits?"
She laughed at him and then looked at me and said "You've seen breasts before, haven't you?"
I said "Of course." She then gave Mark a look like what's the big deal and the devilish grin returned. She put her hands on the bottom of her shirt and lifted it up to give us a quick flash. Kaye let out a little yell and Mark and I just laughed.
Sue sat back down next to Kaye and the four of us were joking and laughing about what had happened. After a little while, Mark said, "Hey, wait a minute. Jim got to see Sue's tits. I didn't get to see Kaye's tits. That's not fair."
Sue laughed and said, "Yeah, Kaye, Mark should get to see your tits." They were having a good time with this but I could see Kaye was a little uncomfortable. She didn't know how to react
