My BF (at the time) and I were quite the adventurous couple. We would always tease each other and push boundaries. One night we went VERY far. We were out on a nice date at a nice hotel. Throughout drinks and dinner we started giving each other dares to do. They were innocent at first, dare you to blow bubbles in your drink, dare you to take a bite of the fake flower on the table, etc.
It soon devolved into more sexual dares tho, things like “I dare you to leave your number with our waitress” or “I dare you to tell our bartender you’re not wearing any panties.” A particularly fun dare was for me to get my nipple noticeably visible through my bralette and dress. That was fun. On our way up to our hotel room after dinner, he dared me to flash the lobby. The elevator was all glass at the back and had a view of the massive lobby/ restaurant area. So I turned around in the elevator that had the glass side looking into the lobby and slid the straps off my dress and lifted my bralette to flash the lobby. I saw one older gentleman see my tits and his jaw dropped.
