【4K shooting HQ/60fps】 'Kai' is a 3D VR work with no male voice at all. The virgin protagonist reunites with his first girlfriend after 10 years, and while surprised by her very assertive attitude, he succumbs to her erotic temptations and enjoys intense eroticism in various positions. The intensity of the facial scenes and the powerful climax during the riding position in Chapter 1 received particularly positive feedback. Additionally, if the quality of the shooting improves, overall satisfaction will likely increase. However, the waist movements in the work feel slightly unnatural, and the short release period since the previous work may have affected the overall quality. Looking forward to future works, it might also be nice if the protagonist's virgin setup changes a bit.
