My brother, living alone, fractures his leg and is in big trouble! To fulfill his desires as a masochist, Natsuki (J-style gyaru) makes a surprise visit to nurse him back to health. With a mischievous, teasing attitude, she torments him with orgasm denial and strict ejaculation control, yet ultimately showers him with sweet, unconditional affection. While breastfeeding him so intensely their bodies seem inseparable, she jerks him off with sensual handjobs until he erupts. Focused entirely on the cowgirl position, this work relentlessly pursues ultimate pleasure.
