I'm staying at my brother's house to prepare for my entrance exams, and my sister-in-law Suzu, whom I hadn't seen in a while, was as cheerful and beautiful as ever—her figure absolutely stunning. One night, I accidentally witnessed my brother and Suzu having sex, and I was completely captivated by her sensual body. From the next day on, she began seducing me one after another. I experienced my first bareback creampie, secret handjobs, and titty fucks right under my brother's nose. Even now, I remain utterly entranced by her temptation.
