This work is truly a masterpiece packed with the bittersweetness and impulsiveness of youth. From the setup where the most beautiful girl in my class is deeply in love with me, I was instantly drawn in. In the accidental alone time scene, her sincere confession, "I can't hold back these feelings...", warmed my heart. Her bloomers outfit after PE class amplified the cuteness, making it a situation where no one could resist. The progression to intimacy felt natural, allowing me to sense the emotional buildup. What stood out most was her desperate effort to please in the cowgirl position, despite her sensitive nature; her earnestness heightened the eroticism, leaving my heart racing. Umi-chan's navy bloomers were indeed top-notch, with the plump lines and butt depictions offering great visual appeal, enhanced by VR's immersive quality that made it feel like she was right there. However, the male actor's simulated genitalia was a bit disappointing, and I agreed with the desire for a longer runtime to savor it more. Overall, it's a fulfilling content that's worth every penny, appealing even to non-fans.
