Daisuke's father remarried Reona, so he has a very young and beautiful stepmother. Because his father is older and busy with work, he no longer pays attention to sexual matters. Meanwhile, Reona has a great sexual desire. Her body feels extremely uncomfortable, restless, and thirsty to "moisten" this "dry land". And when Reona's unbearable lust overwhelms her, she turns to Daisuke. He is also in his prime and curious about sex, so they quickly understand each other and immerse themselves in the depths of lust. Daisuke's hard cock makes Reona climax again and again. Every time her husband leaves the house, just two seconds later, Daisuke immediately thrusts his cock deep inside her, fucks her, and ejaculates all his sperm inside her!
