Actually, about a dozen years ago, I had an assistant in her early 30s, married, had three small kids. You wouldn't know it. Hot. Very hot, leggy, slender, long haired blond. AND... it got to where she'd mumble things under her breath when I'd talk about my dating exploits like, "now I know what you like" and "wish that were me" kind of stuff. And I'm thinking, did I hear her right?
So one day she calls me at home to ask if she can come over, she bought something for me. Okay. She comes over and is wearing the tightest damn pants, like a second skin. Really showed off the shape of her lovely little butt. She had bought a couple of little things to hang on the wall. I know the real reason she was there was to f@ck. But she's married, I know her husband, and she's my worker. I would've LOVED to nail her, still would as a matter of fact, but I can't say it would've been a good move. Then I met someone soon after and got involved.
I did contact her a couple of years ago, and when she answered the phone, I said, "Hi" and she blurted out,. "Hi HONEY!!!!" She mistook me for someone else, and since I don't sound like her husband, I'm guessing I must've sounded like her lover. Oh man! Yeah, so, we spoke a bit but you could see she wasn't interested anymore, I suppose she had her boy toy.
Buit aside from my account of how a woman can indeed be hot even after popping out three kids, to the OP here's another thought:
If she's a SINGLE mom with THREE kids, her bait of sex could be to hook a dad who'll help support them all. Wear two gloves.
