I love my girlfriend, but we've hit a rut. When I visit her place, her younger sister Emi always clings to me affectionately. At first, I thought she was just a clingy kid, but never imagined she'd be such a total slut! Her innocent demeanor while seducing me—maybe because my girlfriend and I had grown distant lately—completely broke my resolve. Emi isn't just involved with me; she's also sleeping with our mother's boyfriend. One immoral encounter after another pulls me deeper into a web I can't escape. I keep creampie-fucking this convenient, promiscuous girl, completely addicted to the pleasure.
