[6 intense scenes, every moment a sexy runaway passion! A top-tier body climaxing repeatedly in dense intercourse—a forbidden drama of ultimate desire!] My first love is about to marry someone—and that someone is my younger sister. I was the one who brought them together. Since then, I've lived in endless regret. My sister suggested a family trip to reminisce before the wedding, but I declined due to work. Now, for these three days while she's away, I want this man to see only me. Sorry for being such a bad older sister... Though I keep regretting inside, I want to do what I can only do now. I want to express all these feelings with my body.
