Starting with a playful mood of idly touching nipples, the innocent smile and persistent nipple teasing by J-style cousin・Shizuki Kokoro quickly had me completely tamed. For those weak to pleasure torture or seeking nipple development, this work is irresistible, with an intense erotic vibe. The filming distance is generally good, with the missionary position offering a close-up face view that enhances immersion, though the cowgirl position could benefit from a closer shot. Compared to the same label's 'Seishun tte...', released 4 months earlier, this piece falls slightly short in direction and angles, possibly due to director differences. Still, the pure white thighs and tight body keep the arousal going, and the creampie scenes are thoroughly enjoyable. Experiencing the evolution of KMPVR in 8K, I fully savored the naughty sex education with my cousin.
