When the secret girls had sex with each other out of curiosity... Yui Sayama, who was so excited, had sex with Yui Sayama until her sexual desire ran out.
Yui-chan and I were good friends because of our indoor hobbies. I thought that sex was only for positive people, but when she told me that she wanted to lose her virginity as soon as possible, I suddenly decided to have sex with her... Seeing Yui naked for the first time. She usually wears plain clothes, so I never noticed that she had such an amazing body even though we were always together. Also, I thought sex was not a big deal, but it felt so good that I couldn't stop shaking my hips. A raw sexual act in which they seek pleasure and devour each other. After all, sex between yin characters is the most erotic.
