[Rokujinchuu (Haraita)] Onee-san ni Osewa Sasete | Let Onee-san Take Care of You (Granblue Fantasy)

Narmaya finds a peculiar medicine that can turn anyone's body and mind into a child, and she is more than willing to provide the care they need. As the Captain regresses, she steps into a nurturing yet intensely physical role, using her lush, heavy breasts to soothe and satisfy his new, smaller needs. From gentle attention to more direct, intimate sensations, this intimate experience explores a unique dynamic of care and pleasure, where every touch is designed to make him feel better and more comfortable in his regressed state.
