Having dropped out of school and holed up at home, I met my relative, Tsubasa, who came to me seeking a better life. She's so beautiful…and while cleaning, her swaying jeans and perky buttocks are irresistible…One day, I found myself losing my temper and penetrating her from behind!…However, my premature ejaculation caused Tsubasa's tight hole to erupt with ejaculation! "Wait, she ejaculated again…?" To avoid being discovered, I denied penetrating her again, using my premature ejaculation to relentlessly thrust and bring Tsubasa to multiple orgasms…!
