She won't let me do anything unless I get in the mood, so I got excited and asked her out on a hot spring trip, but to make it harder for us to have sex, she brought her younger sister with me and ended up sinking... But I thought it was my girlfriend's younger sister Mio. Contrary to her innocent appearance, she is a secret nymphomaniac and seduces me as soon as we arrive at the hotel. ``Rubbing me with your hands isn't cheating, right? I don't know.'' Even though I feel guilty, I try to seduce my little sister. I got on top of her, and she continued to have sex with me for three consecutive nights, and I was completely destroyed by her cute face, whispered dirty words, and techniques.
