A shy man lives with the woman he is about to marry. While his girlfriend is away on business, her adult older sister Ichika comes to visit and immediately sees how easy he is to tease. She traps him between her long legs, grinds his cock with her feet, wraps him up during slow cowgirl and makes him lick her legs. Behind his girlfriend’s back, she rides him through repeated creampies until he is completely defeated and obsessed with her legs.
