I am the wife who married into this family...and this man is my husband's father...my father-in-law...I once gave my father-in-law an aphrodisiac on a whim...and when I saw my father-in-law's excited body, I got turned on and ended up seducing him...At first my father-in-law was very keen on me, but it seemed like he was avoiding a relationship with me out of consideration for my husband...so we came on a family trip to change things up...
