NFDM-457 I was used as a sex toy by my step-sister who lived with me and was made to ejaculate many times. Aoi Rena

Taro's father remarried and he ended up living with his stepmother and step-sister. His step-sister, Rena, is one year younger than him and seems like a kind girl with a constant smile on her face, but when they first met, she gave him a footjob under the table, even though his parents were right next to him, and made him ejaculate. From that moment on, Taro was destined to become Rena's sex slave.
