Her blouse

You decide to make her take off her blouse.

"Mom, take off your blouse for me" You command, not knowing if it will work.

Your mom looks up at you briefly, before standing up. "Okay" she says. "If that is what you want honey" she says as she grasps both sides of her loose, purple blouse with each hand and slowly lifts it over her flat, slim stomach and then over her boobs, revealing a red lacy bra which is just see-through enough to be able to get a rough idea of what her boobs might look like. Unfortunately, the intricate pattern cleverly covers her nipples so that not everything is on show. "Is that better honey?" She asks almost seductively.

You can't help but stare, almost not beliving what just happened before finially stuttering out "u-urm yeah. Thanks mom!".

"You're welcome honey. Anything for you. You are my son after all; I HAVE to do whatever you tell me" she explains, emphasizing the word "have".

Now you know she will do anything you ask...
