ROYD-259 My sister is plain and modest, but when she takes off her glasses, she turns out to be a stunning beauty, and when I couldn't resist, she started with a dry hump and then inserted it raw, giving me my first creampie. Ririka Amami

Lacking confidence in her appearance, her stepsister has always avoided the public eye. But it's her younger stepbrother who teaches her how to do makeup and choose the right clothes. Little by little, she changes. Her smile is more refined, her beauty is more polished. As she begins to attract attention, her stepbrother's heart begins to race. "I've always liked you," she says, but she rejects him. "We're brother and sister," he says, unable to give up. As his feelings grow, the two make a promise. --You don't have to put it in. I just want to be close together. But unable to resist the overflowing heat, they cross the forbidden line. It was only supposed to be once. But even so, she keeps her distance. "I didn't want you to hate me...because I fell in love with you..." Caught between guilt and love, the two seek each other again and again. There's no turning back.
