(28M)took an 8 hour flight with my wife (28F) to meet her ex AMA

So it all started as a joke I asked her if we can go meet her ex. This particular ex who has had many sexual encounters with my wife and was currently in touch with her. She is aware that I get really turned on about her hotpast but little did I know that she would really accept this proposal at first I wasn't even sure but we went. So we decided to meet up for a day go clubbing and enjoy ourselves also my wife had little surprise for me but wouldn't tell me anything about it so she wore a shirt and a skirt but little did I know that she wore a mesh lingerie inside we are drinking and talking we go to the dance floor while her ex was just standing away from us so she invites him and here we are dancing in the middle surrounded by crowd drunk and she starts getting close to me grinds me and I can see her ex literally just starting at us and then time for my surprise she just takes off her shirt I was shocked and turned on at the same time and her ex's reaction was priceless he gets a little glimpse and she turns to me and says do you like the surprise. Also I posted the picture of her outfit on my account.
