ROYD-294 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 bare-knuckle intercrural sex and gave me my first creampie. Miyu Otori

A word from her brother transformed her plain sister, who used to go to school without makeup. She treasured those words and improved herself. She was happy when her brother called her "beautiful." But her brother couldn't resist and tried to cross the line between siblings. The sister proposed a promise to just do some "sumata" (dry sex). And so a wall was created. But when she thought of her brother, her heart ached. Even though she tried to control herself with reason, she wanted to touch his skin... "I want you to not just do some sumata, but to penetrate me." She found herself saying it out loud. Alone she couldn't take the step. But being with her brother gave her courage. She wanted him to stay with her and watch over her forever. Her brother responded to his sister's request with a kiss.
