In this volume of "Beautiful Collection," we have the lovely older sister type, Reo Tsubaki! She lives alone with her younger sister after their parents passed away. Her little sister has started dating someone really hot, but she can't help feeling attracted to him too. Whenever her sister isn't home, she finds herself thinking about him and masturbating while fantasizing about them together. One day, he shows up at her place when her sister isn't there. They both know they shouldn't be doing this since he's her sister's boyfriend, but their bodies just can't resist each other. Before they know it, things escalate, and they end up having sex right there on the spot!
