I want to know how to ask my mother in law to have sex?

[Secret E]

firstly, i dont need the ewww gross, what about you wife, dont do it, yada yada crap ok. i know all this stuff. if u clicked this then u must want to answer. and i want an answer to the question. not some other crap ok. ok now, she lives in our house, we are alone all of the time, and she hasnt had any in years! she doesnt drink, so how the hell do i go about trying something with her? because if she isnt into it, then i could lose my wife. i need to test the waters or something. need some ideas, cause i have wanted her for along time now. remember, just answer what im asking or dont answer at all!! thank you =]
