^ fvck ya, i agree. Not sure why so many guys on here are so quick to say no dont fvck your land lady or married chicks....probably just jealous of your options. If you want it, take it. Do you want to be alpha or beta?
if you are smart about things then there shouldnt be a problem. you have to be upfront with her in the beginning. Ask her what she wants, fun or an LTR? If she says LTR then ya dont do it unless you want issues later on.
