I have a girlfriend who hates sex, leaving me frustrated. To relieve my sexual urges, I went to a brothel and unexpectedly ran into her younger sister! It turns out that I had been secretly visiting brothels behind my girlfriend's back, and her sister had been working at a brothel in secret from her family. Sharing this secret brought us closer. I was drawn to her large breasts and the fact that she let me ejaculate inside her. I started sneaking off to see her and have sex with her every day. And finally... I had massive internal ejaculation sex in front of my girlfriend！！
