While job hunting, I ended up staying at my older brother's house for a while. One day, I came home to find my sister-in-law, Rika, in the middle of masturbating. From that moment on, our life together began—with her fully aware of my presence. She constantly seduced me, and after breakfast, I experienced my first bareback creampie sex with her. Since then, she continued to lure me in every day—bathing together, even showing me the sex she had with my brother. And once again today, our forbidden relationship deepened through creampie sex.
