The stepsister, who came from her parents' remarriage, is a proud but sexy woman who enjoys sex and gets masturbated every day. (miru SSIS-938)

The younger sister, who appeared after her father's remarriage, is an extremely arrogant and mischievous girl who enjoys catching men on the street. She constantly mocks her brother for being "ugly," "lacking vitality," and "having a tainted virginity." However, slowly, the feeling of being teased by her begins to become interesting... One day, the brother was looking at pornography in the living room when his sister discovered him. His erect penis was witnessed, which was terrifying—he was about to be ridiculed again... But unexpectedly, his sister reacted like this: "When it's erect, your penis looks pretty good! Well then, I'll take your virginity away!" Then, she began to stimulate his virginity: erection, nipple rubbing, counting down to ejaculation—the little devil sister made her brother violate her everywhere! His erect penis was sucked in the morning, their private moments in the kitchen were violated, and they even had sex in yukatas after festivals. He was controlled by his sister, violated by her everywhere!
