Yui suffers from a sexless marriage. This voluptuous G-cup beauty can no longer endure the frustration and dives into an affair. Her sensitive pussy gets instantly wet just from having her breasts licked. When her slit is carefully teased with fingers and tongue, she writhes in ecstasy, moaning loudly. Penetrated first from behind, then switching to cowgirl and missionary positions, she's finally filled with a creampie. Her physical and emotional transformation is meticulously portrayed throughout the entire encounter.
