HZGD-293 Kasumi Tsukino has sex with a married man who has been saving up his sperm for 773 days and has a passionate affair with him after removing the condom

"Kasumi" contacts her husband's boss, Oshima, who she has been interested in for a while, and invites him to have an affair... It was supposed to be just a little snack, but Kasumi becomes addicted to his insatiable cock, which doesn't go soft no matter how many times he ejaculates, unlike her husband's. Even though she knows it's wrong, she becomes engrossed in the affair and doesn't go home until the morning, drowning in sex and climaxing to the point of death in this super-intelligent act of infidelity!
