The shy me was pitied by a schoolgirl's younger sister who said "just rub, that's all" and let me do sumata, but we got too excited and my cock slipped right into her wet pussy! "Huh!? It's inside!?" But we couldn't stop and I creampie'd her! Usami Reina

The younger sister, a schoolgirl, lies napping with her panties off, causing her older brother to nervously start jerking off, unable to resist. But when she notices him, she's disgusted by her brother's perverted act and angrily snaps at him. Seeing her reaction, the brother begins to feel a bit sorry for her. He offers to help, but she still can't climax, ultimately leading the brother to fully persuade her. As the situation unfolds, their relationship gradually grows deeper.
