I watched the latest work of Arina Shin, and it's truly a spearhead in the competitive AV world! First off, the title delivers on its promise with a massive injection scenario featuring a virile man performing 20 vaginal ejaculations. The climax scenes with her slender body arching back are breathtaking, and varied performances like facial cumshots under guillotine restraint and forced implantation using toys shine brightly. Particularly, the close-ups of the union, her climaxing prowess, and moans are seared into memory, making it irresistibly rewatchable. On the flip side, the mechanical repetition of creampie scenes and overuse of close-ups felt slightly off, but overall, her bright and voracious nature explodes on screen, with excellent camera work. While themed around impregnation, the fun of the concept outweighs the drama, making it a must-see masterpiece for fans!
