寝取主義者の花嫁弄り！ ～婚約者があんな声で喘ぐのを兄貴は知らない～

I frequently visited my hated older brother Kenichi's house because I wanted to see his fiancée, Miharu. She had all the qualities of a perfect wife: well-behaved, attractive, skilled in household chores and kind-hearted. Unlike the other women I had been involved with, she possessed the qualities of an ideal wife, which aroused me intensely. I wanted to completely possess and dominate her. The dark desire grew stronger every day. Then, I discovered a digital camera in her room, providing the perfect opportunity. She likely took the pictures out of curiosity. Among the happy photos of the couple, I found a few indecent pictures of Miharu engaging in masturbation. They were shockingly explicit and far beyond what I expected from her usual behavior, igniting my primal instincts. That alone was more than enough. I seized the chance to ruin everything. Brother, don't ever think you'll find happiness because that woman belongs to me. Their wedding is only two weeks away. Now, I eagerly anticipate how I will destroy their happiness.
