[Ebisujima Misato] Yuma-chan and the Sea Part 2

Sun-kissed Yuma-chan drags her favorite onii-san to the beach for a swim date, showing off a frilled bikini she knows exactly how to weaponize. Between waves and lazy afternoons in the shade, her bold confessions—wanting to be with him more, even staying at his house—leave the poor man sweating through excuses he was never going to win. When she flashes that fanged grin and coos "then it's decided ♥," his fate as this little siren's summer catch is thoroughly sealed.
