One night, my grown-up nieces and I were sleeping by the river, just like we used to. My mischievous sisters were playing with my nipples and penis from both sides, forcing them to fight back and teach me a lesson. The harshness of being an adult. PIYO-018

My niece and sister, whom I hadn't seen in a long time, have now grown up. That night, I decided to sleep by the river as usual. My niece and sister are both a little older than me. He playfully teased my nipples and penis from both sides. If such cute girls attacked me from both sides… I would ejaculate painfully, even though I know it's not good. But those spoiled sisters needed to be punished. I defeated them with my sister's bowl, teaching them the harshness of adulthood!
