Seduced by my girlfriend's busty younger sister, I engaged in intense intercourse. Under forbidden circumstances, my erection continued to be drained of my seed. Hoshino Natsuki EBOD-943

One day when I went to my girlfriend's house, her cute younger sister, Xia Yue, came out to greet me. Xia Yue, who was even more cheerful and had bigger breasts than her older sister, was not wearing a bra and her breasts were exposed. Was she trying to seduce me? "Let's find a way to deal with the discomfort in my uterus." Even though we weren't dating, she suddenly wanted to have a baby!? Faced with this lustful body that was in heat and wanted to get pregnant, even though I knew it was impossible, I was still excited and got an erection. So I secretly let her continue to drain my juices without telling my girlfriend.
