Son mom barely spoken in a decade has become like a stranger how can i seduce with little to no risk of anyone finding out

[Fantasyfulfillment]

Short version im early thirties she is 60 slim 5ft 4 very by the book and religious. She left when I was y**** and now she remarried and lives 4 hours away. How can I respectfully go about making this happen even if a once off. I look almost like my dad my family always commenting so that's a start.
