My upstairs neighbor, Mr. Samejima, was clearly one of those types—intimidating in appearance yet exuding a strangely alluring aura. His habit of smoking in the shared space while shouting loudly every day constantly infuriated my usually serious wife, who would often blow up in anger. As a peace-loving husband, I'd always calm her down with a casual "Now, now, relax," but that dynamic would eventually change. About two weeks later, I accidentally witnessed my wife moaning as Samejima stimulated her anus, and from that moment, I became aware of a hidden side deep within her heart.
