Three days ago, my sister's family went on a trip, and I was asked to take care of my nephew, Takele-kun, since my son couldn't cook for himself. With his school's prefectural tournament coming up soon, Takele-kun had been struggling to practice regularly due to the recent bad weather, so he spent his days diligently working out. His body was filled with youthful, firm, and well-developed muscles—completely opposite to my husband's deteriorating physique. I couldn't stop staring at his beautiful body. Eventually, I found myself licking his tired biceps and abs after his workout. When he woke up, I pinned him down and took his virginity.
