My wife Rinrin and I have been married for five years, and including our cohabitation period, we've been together for ten. Now we sleep in separate beds, and we haven't had sex in over a year. Our enjoyment comes from having BBQs with the Uchimura couple who live in the same apartment building. We both struggle with being sexless. During one of these BBQs, I said 'Let's swap,' which gave Mr. Uchimura the idea to exchange spouses for a day. We started this to stir up each other's jealousy, but I never thought Rinrin would be taken...
