I developed a hiccup fetish [I Like Spicy Food]

So I went to this restaurant w my boyfriend and we ended up getting a table way in the back where there wasn’t any other party around us except for 15/20ft away. Anyway, my boyfriend and I had spent the whole day out on the lake, swimming, having some drinks, having a great time. I was still wearing my swimsuit but with a, pretty much, a belly shirt and some shorts. We had ordered already and were drinking our beers. Suddenly, I hiccuped! My boyfriend already loves it when I wear short shirts that expose my bellybutton, but especially loves it when I get the hiccups. Anyway, so as I begin hiccuping really fast, as they always do when they start, my bf sits closer to me and puts one arm around me and the other on my stomach to feel my hiccups. He started to move down to my bellybutton and started playing with my bellybutton while I had a strong case of the hiccups! I was pretty embarrassed at first but he told me that it was ok and he actually was really into my hiccups! I wasn’t expecting that! He told me to sit back , and I did. He wanted to watch my hiccups and he wanted to “admire my bellybutton while I hiccuped” and he “loved to listen to my hiccups”. Ever since that night at the restaurant, we have had many similar experiences where I get the hiccups and he becomes very flirtatious with my bellybutton. So now, both have a bellybutton and hiccup fetish.
