When I went to my brother's house for the first time in a while, my brother's wife suddenly asked me to share my sperm with her! Apparently, my brother doesn't come home from work until late at night or early in the morning, so they neglect their nighttime activities. My brother's wife, who is anxious about not being able to have a child, has her brother's sperm as her target! I was confused but satisfied with the windfall raw fuck, but my brother's wife said, "One shot isn't enough!" and held me down as I tried to escape, and continued to piston my sperm until it dried up! "I can't produce any more sperm! Please forgive me!"
