Swimming club veteran of 9 years! Momoka-chan, who made it to the prefectural championships, has a bodybuilder's physique with defined abs, firm buttocks and thighs, and proudly displays her F-cup breasts. Her steel-like athletic muscles are irresistibly tantalizing! Such a Momoka-chan becomes an obedient little sister and engages in incestuous sexual activities with her perverted older brother! Her muscular body is licked all over, and her brother's rock-hard muscle cock is thrust into her pussy, making her moan in ecstasy from his fierce piston-like thrusts!
