Ep. 6: Nana Teases Aki and Challenges Ayaka to a Summer Swimming Competition

Aki encounters Nana, Ayaka’s sister, who is changing in his room. Nana teases him by calling him feminine and attempting to verify his anatomy. She stays for the summer, and the pair grow closer through shared activities like sleeping in the same bed and playing video games. Later, at a public pool, Nana’s friends Maiko and Mea flirt with Aki using similar remarks. Nana then challenges Ayaka to a swimming race where the victor gains control over Aki. The competitors remain evenly matched, and the facility closes before a winner is decided.
