Mami Sakurai is a slender and neat exclusive older sister. She has to move a lot because it's a shoot... but we decided to restrain her tightly so that she can cum to her heart's content without worrying about that. Even when she's climaxing, we continue to thrust her pistons even after she's at her limit! Her convulsions don't stop, her nipples are hard, and her pussy is so sensitive it feels like it's melting... but we continue to thrust! Have you ever seen a beautiful woman who is forced to cum even when she's exhausted, and who only seeks pleasure?
