Gente,¿Como Hago Para tener sexo con ella?

I've wanted to have relationships with a woman for a long time, it's a distant relative (is that still incest?) the thing is, she's really great (if you want to know how sexy she is send a private message) but she logically is married to an idiot who spends all his time traveling, she logically knows me, sees me as just another distant relative, how do I get close to her first? Honestly I want to have sex with her so please answer and help me, I want her to also want me too, thank you very much, thanks
