Ever since I was young, my older brother could do anything, and on top of that, his wife was a beautiful woman, making me constantly feel inferior. But one day, everything changed when I had bareback sex with my sister-in-law. Even with my brother nearby, she gave me blowjobs and flaunted her sex life with him right in front of me. My mind gradually spiraled into chaos, until finally, right beside my brother, I ended up having bareback sex with Yuki, my sister-in-law.
