Taro's father remarried and now lives with his mother and sister-in-law. I thought that my sister-in-law, "Rena", who was a year younger than me, was a gentle girl who always smiled, but when we met, she gave me a footjob under the table even though her parents were right next to me. I was made to ejaculate. From then on, his older brother Taro was destined to become his sister Rena's "sex slave".
