Even after marriage, Yua still felt uneasy about her father-in-law. He was selfish, egotistical, vulgar, and crude. On a day when her husband was away on a business trip, he suddenly showed up at her home—clearly having timed his visit when she was alone. Slurping loudly, he praised Yua's natural juices while licking every inch of her body. Despite being middle-aged, his skilled oral technique brought the cheating wife to a dripping, lustful climax.

Over the three days her husband was gone, the big-titted wife fell deep into a sticky, obsessive affair. A full episode depicting her descent into infidelity.
