After actually watching this work, Matsumoto Riho's portrayal of the seductive older sister was overwhelming! The sensual tone in her voice when tempting her sister's boyfriend was irresistible, and her playful teasing of men was both adorable and endlessly engaging. Her defenseless look in a camisole heightened the eroticism, and the gap with her scary expression at the end made my heart skip a beat. Her beautiful, plump busty body swayed like a lethal weapon, and the intense pounding in fishnet stockings and sexy lingerie was thrilling. The younger sister role played by Fukuzuki Mei was also busty and cute, breaking the usual premise of the older sister stealing away due to her bust size, but Riho's constant flirting made it easy to overlook details and just enjoy. The direct offer of raw sex blew away rationality in seconds, and the continuous creampie scenes mixed guilt and pleasure into an intensely fiery experience! The camera work was spot-on, allowing full appreciation of Riho's curvaceous body, and fans of Isoyama Sayaka or Chitose Yoshino will definitely get hooked on this worthy entry in the famed series. I'll keep supporting her from now on!
