The father-in-law is aroused by his son's wife's body. Excited by the soft, large breasts of the wife, which can be seen even through her clothes, the father-in-law sneaks into the bedroom where his son and wife are sleeping and starts to fondle the sleeping wife's body. The wife wakes up in the middle of the night, noticing something strange, and moans in pleasure for the first time in a long time. The father-in-law's hard, large dick is inserted into her even though her husband is sleeping next to her.
