My wife and I are married for about a decade now. We both ran into each other in college, we feel for each other, we dated for a few years and then we decided to marry each other. Now, about ten years later we are still a happily married, but childless couple. We still love each other. We still fuck each other. And meanwhile we are best friends too.
To keep our marriage up and running we established a few traditions over the years. One of them is date night. We go out at least twice each month to have dinner together. In the best restaurants in town. Always dressed to impress. No, no formal wear, just the best stuff we have in our closets.
We both, my wife and I, we love date night. It gives us time out of house to talk with each other. To show off each other. To spent time with each other while wearing something different then your average comfy stay at home clothes. But one especially good one, one especially hot date night will never leave my mind again. It probably will stay with me forever.
