Not long after completing the graduation exam, Ariga's sister hurriedly asked her parents for permission to go to her brother's house in the city to play for a few days. This is also understandable when she and her cousin have been in love for a long time even though they know that it is incest and extremely wrong. That day, my sister-in-law had just come out of the house early in the morning, and it was also time for Ariga to wake up, she sneaked into each room to find her cousin and happened to find him sleeping very soundly. She crept in, then gently found the erect penis under the thin blanket and kept sucking and licking it as if he was in estrus, which suddenly woke him up. He taught her a "lesson" to remember life because he dared to break other people's sleep.
