My Boyfriend's Mother I'd Like to Fuck

I've been with my boyfriend for about a year now, but I've always liked girls. I just always date guys because of my family. Anyways, I started talking to my boyfriends mom on the phone ( long distance thing) and she started saying things like "everyone can probably see my ass"– she said it like five times, she was in a night gown because it was like 3 am. Then she went on to say that she wasn't wearing a bra. Just thinking about it turned me on, I just wanna have my way with her, I feel like she knows, that's why she said those things. I want her so fucking bad.
