The father-in-law, reeking of alcohol, thrust his enormous, hard penis deep into the woman's vagina, bringing the son to orgasm and making her pregnant. (Misaki Kana, NGOD-282)

The father-in-law lives in the apartment next door. A volatile and alcoholic "husband's father," he's always been disliked by his earnest wife, Kana. When she and her husband visit her father-in-law's house, seeing his continued decadent lifestyle and dilapidated room, Kana sighs. The following week, Kana goes alone to her father-in-law's apartment to deliver business documents. But there, her father-in-law, aroused by the unsuspecting woman's body, gets an erection—a thick, hard, middle-aged man's penis—and approaches "her son's wife"...!
