Because it's a couple who love each other ... let's experience swapping! Nakazawa is unable to satisfy his wife because he is tired of his business. One day, by witnessing his wife masturbating, he decides to face swapping. A couple with an age gap living in an apartment. I decided to accept an invitation from her neighbor to exchange husbands and wives, but the result was...? "Swap experience of serious couple with age difference". Includes two powerful middle stories! It tastes great!
