[Chinese]FNS-214 "Eh... Sana-chan!?" Mistakenly deep-kissed her sister, had sex with her sister who blushed while entwining tongues for the first time. ... Ikuta Sana

It seems that her family will be away, so I stay at her house in high spirits. Of course, the two of them were making out, and at night, he wanted to have sex with her, so he kissed her deeply, but she resisted, so when he looked closely, he realized that the person he was kissing was her younger sister, Sana. He immediately apologizes, but it seems like it was Sana's first kiss, so he's in a big pinch. But Sana-chan was blushing and had an expression that I couldn't tell whether she was angry or sad. The next day, when I woke up, Sana-chan came and asked me to kiss her with her cute lips.
