For me I bought my wife a real cheeky cut bikini. She wore it to the beach and didn't mind it. She kept adjusting because her ass would eat that bikini up. Then I asked if she would want a thong bikini instead. She didn't say no. So I bought her one. She would start off wearing it under beach shorts. Now she still wears the shorts to the beach but she will take them off showing her thong while we are relaxing or in the water.Awesome thread! Been trying to convince my wife to wear a thong bikini for a while now, any tips?
