On the day their son was scheduled to return home for his mother's seventh memorial, he receives sudden shocking news from his father—that he's getting married. Returning to the family home, the son finds his father with a young, beautiful wife. Despite their age gap, the couple appears deeply affectionate, sharing a warm meal together. The father is passionately learning to cook, striving to recreate the late mother's flavors. When asked if he'd prefer a younger brother or sister, the son hesitates—but the conversation shifts as the father gets drunk and starts rambling. He reveals his new wife was once his subordinate, and how he fell for her kindness. They discuss cooking, the son's love life, and their desire for children—though the father refuses. Then, the beautiful young wife turns her attention to the son, seductively touching his cock through his pants. He responds instantly, his clothes quickly undone as she gently kisses him, whispering, "Is this okay?" She removes his underwear and carefully licks his penis, checking how long it's been and how much cum has built up, then performs a meticulous blowjob with varying rhythms. She mounts him, riding hard—clearly pent up—and cums repeatedly. Switching to rear-mounted cowgirl, she takes deep, pounding thrusts until climax. As she moans, "Go all the way inside," "Ah, amazing," the intense motion almost wakes the drunken father, but luckily, he only stirs before passing out again. The son resumes from behind, muffling her moans with his hand. In standing doggy style, she begs, "Harder," "So stiff, feels incredible." She strips off her panties, now fully naked. In missionary position, she gasps, "I'm about to cum," "Cum deep inside," "Let's do this again secretly, without Tateshi-san (father) knowing."
