I'm the section chief, who got drunk and passed out at a company drinking party, and was taken home by my subordinate. While I lay there completely drunk and unable to move, my subordinate suddenly started touching my wife's breasts, pretending it was a massage. "I heard from the chief that you two haven't been intimate lately," he said, pressing forward aggressively. My wife initially refused, but overwhelmed by my aroused subordinate, she apologized, saying "I'm sorry, honey," and began having sex with him right in front of me. Watching my wife, who had been in a sexless marriage, get stolen by my subordinate, moaning and looking aroused, my crotch inexplicably got hard. Excited by the sight of my wife climaxing repeatedly on my subordinate's dick, I kept pretending to be asleep until it was all over.
Close-range NTR is nice, isn't it. Indeed, the male actor in this work doesn't use particularly clever words, yet the development where the protagonist's wife easily opens her heart to him left me with a strong shock and a sense of helplessness. "So easily, my wife falls for another man..." That unbearable feeling is exactly the charm of NTR works, I felt.
What stood out to me especially was the scene where her proud big breasts are freely groped right in front of him. In the story, the protagonist is set to be asleep, so the thrill of observing his wife being embraced by another man right next to him, making expressions he never gets to see up close, was irresistible. This closeness intensified the feeling of being cuckolded, and I think it was extremely effective.
