SONE-127 | I became lustful for my girlfriend's younger sister who couldn't say "stop" and secretly continued to fuck her... and she unexpectedly became addicted to my dick. Kokoro Asano

When I went to her house to play, I encountered a really cute little sister. She can't help but worry about her sister more than herself. I decided to attack him, but although he didn't like it, his resistance was weak. I boldly fondle her breasts, give her fingering, and give her a strong blowjob. I kept the momentum going and fucked her. Ever since that day, my girlfriend's sister has become addicted to my cock, and every day I secretly fuck her without her knowing.
