A husband who enjoys letting his wife be cuckolded, a husband who takes a picture of his wife being fucked and ejaculates, couples who cum over and over again while swapping wives, a husband who wants to embrace his wife right after she's been embraced by another man, a husband whose sexual desire is heightened by his wife sleeping with anyone, and a wife who becomes even more lewd... A married woman goes crazy with her sexual sensitivity in her ever-increasing sex life! An insatiable desire for Kokoro and an unrelenting sexual desire! This is middle-aged and elderly sex!!
