My wifey D and I were on vacation and to surprise her I bought her a white thong for the beach. When i showed it to her she raised her eyebrows and told me she would promise anything. I knew that if I left her to think about it that she would come to be excited by it.
On our first day there she came out of the bathroom with it on and a smile to boot. She told me she would wear it but we'd have to be further from most of the crowd on the beach. We found a spot and lay down to enjoy the sun. There were a few people who came by but not many and I could tell she was comfortable. So, a few days later I decided to up the ante and dare her to go in the water and pull them down for me. Again she thought about it for a good while and after lunch said she was ready (nobody was around).
She went in the water and not only pulled them down but took them off! I took a few pictures and attached the best ones that don't show her face. It was her first time doing any kind of dares and injected some kinky fun into the vacation. We are open to suggestions and other dares.
