FNS-214 · "Eh... Sana-chan!?" Mistakenly Had a Deep French Kiss With My Girlfriend's Sister, Then Fucked Her... Sana Ikuta

Since my girlfriend's family was going to be away, I excitedly went to stay over at her house. Of course, we were flirting, and at night, wanting to have sex, I gave her a deep kiss. However, she resisted, and when I looked closely, the person I was kissing was her younger sister, Sana-chan. I apologized immediately, but it seemed it was Sana-chan's first kiss, putting me in a huge pinch. But Sana-chan had a blushing expression, and I couldn't tell if she was angry or sad. The next day, when I woke up, Sana-chan came to me and tempted me with her cute lips, saying, "I want you to kiss me."
