You see an ultimate MILF

You turn around to see who snuck behind you.

You see a woman, probably in her forties, wearing a black one piece swimsuit. Her breasts look as enormous as the girl you were spying on. If you had to guess, you'd say she is...

"So, another neighborhood pervert spying on our Emma, isn't it?", she says with an expression that could be either amused or disgusted, possibly both.

Emma's mother, definitely. Yep, she got them from her mother.

"I was just... I mean", you stammer.

"Yeah, yeah, save it for the police. It's not the first time we've had to deal with the likes of you", she says coldly as she takes out a cellphone out of her bag.

"Call 911? Not if I can do anything about it!", you think as you lunge at her, popping of the cap of your Sharpie. You manage to knock her off balance and make her fall on her back. You land on top of her body and straddle her stomach with your legs. Your scribble the words "RYAN'S MILF" on the nearest available place which happens to be her chest. The woman stops resisting and looks up at you with an inert expression. "Sorry about that, Master", she says to you.

"Master? Did you just call me that?", you confirm. "Yes, Master", she answers without missing a beat.

Well, that was not exactly the test I was going to perform, but the most important thing is the Sharpie does in fact work on living people. You survey your current situation. It's been merely a minute or two since Emma's Mom caught you by surprise. You are straddled on top of her, with your cock, still ready to pop at the slightest stimulation, and she is in your thrall.
