Is it normal not to fuck the maid?

My uncle has a maid and I'm staying with him. Aunt's in New York, kids are at summer camp, uncle's at the office for at least 3 more hours, and the dog ain't sayin' shit. I'm 21 and hornier than anyone I've ever met. Maid's pretty damn decent-looking. Shy, no husband, no bf. Thinks I'm really funny. She's Latina and would love, it seems, to get with a successful young man. She lives alone and doesn't get out much. I'm an attractive guy and I would LOVE a blowjob from her. But I don't know how to insinuate it properly.

is it normal to want women to make the first move? I'm definitely not shy--I told her she's beautiful and I asked her if she was married. I asked her what "she does to relax and have fun" in a really suggestive manner. Why doesn't she make a pass at me? Should I just go up to her and say, "Hey, uh, how about you just let me vacuum that rug later and you and I can take a 10-minute break together."? Even then, I'm not sure she would get the hint. She's vacuuming in the other room right now and I just want to feel between her legs while she blows me. How could she not want that? Is she simply being shy or does she get the hint and think I'm a pervert?

C'mon everyone likes sex/fooling around when there are no repercussions! She's not like a dime piece either and I doubt she's getting any from elsewhere. What do I do this is driving me nuts! Especially because she's cutting into my jerking time right now and a 'substitute' for masturbation would be quite welcome in my book.
