is it normal that my wife wants to get naked at a pool party this week

Party went well. After a couple rounds of cocktails a few of the ladies tossed their tops by the wayside, my wife was included in that group. She gave me a curious glance which I assumed meant she wanted to know if it was ok to go naked. I just winked at her. She stepped in to the diving board and bounced a few times to get people's attention, then she gracefully did a dive into the pool. When she surfaced she had her bottoms in her hand and tossed them at me. I waved them in the air to make sure folks knew she was naked. One of the guys hurried to swim her way. They hung onto the pool edge chatting for a bit. Later the wife said he slid a finger into her, and then another. She returned the favor when she grabbed his hard dick for a few tugs. That's as far as anything went, but I'm betting the summer might be a bit hotter at the pool this year...
