This is the only work where you can see MINAMO's anus in such close-up! Attracted by this catchphrase, I immediately watched it. The story about a lively college girl sister who, while nursing her brother, notices his big penis and, as if to vent her frustration over a canceled date, repeatedly extracts his sperm in a big butt cowgirl position, fully showcases the forceful and sexy older sister character. MINAMO's natural vibe perfectly matches the role of a sister who cares for her brother, and especially in the last scene, seeing her dancing and laughing made me feel happy too. However, many voices expressed disappointment every time the brother actor's face flashed by, which was indeed a bit regrettable. Still, MINAMO's anus close-up is magnificent, significantly enhancing the value of this work.
