Suzu, a pure-hearted girl in a school uniform, fell in love with her sister's boyfriend at first sight. She was always watching her sister's boyfriend from behind a pillar. She took advantage of her sister's innocent feelings for her, who was so devotedly in love with her... When she was scolded and feeling down, she was pampered, and when they were fighting and feeling irritated, she was roughly creampied. Still, her sister tries to accept the feelings of her sister's boyfriend, who is her type, so she uses her pussy as a convenient sex friend and an outlet for her sexual desires, and uses it as much as she wants.
