9 years in the swimming club! Momoka-chan, a full-fledged swimming girl who went to the prefectural tournament. Abdominal muscles, tight buttocks and thighs, firm F-cup boobs, and a muscular athletic body like steel are irresistible! Such Momoka-chan becomes an obedient compliant sister and develops carnal intimacy with a perverted brother! Her macho body is still twisted, and a muscle stick that stands as stiff as her sister's body is screwed into her pussy, and she faints in agony with her brother's violent piston attack!
