A neighboring couple had a very boring sex life, so they proposed to Tsumugi Akari's husband about the idea of swapping partners to increase their sexual excitement. Akari thought her good husband would never agree to this, but surprisingly, he accepted the proposal, and Akari began living with the neighbor, who was very skilled in bed, and she reached orgasm many times. On the other hand, Akari's husband was foolish to exchange his sweet wife for an older woman; it seemed like he preferred to fly planes :)))}
