Do as mother says

As his mother lead him to their bedroom, Josh remained in shock that he was married to his own mother. But also to some degree at how fantastic she looked. He'd always known his mother was attractive, but it looked like in this changed reality she'd went to great lengths to keep her body in tremendous shape. Especially given she had apparently given birth to a child when she was already a mother to grown children.

They had barely crossed the threshold of the room when his lingerie clad mother spun him in front of her and shoved him onto his back on the bed. She seductively climbed on top of him, looking down at him over her full breasts. "Come on baby, show mommy how much you love her.", she purred. A moment later you felt your pants being yanked down, nearly torn from your body. Your erection was now fully presented before the woman who birthed and raised you.

"Good," she said, "but I think you can show mother even better.", she spoke in her rich, sensual voice before grabbing hold of your balls and giving them a light squeeze. "You know what mommy wants, so don't make me wait little man. This may be a good, hard erection for your sister - but you know mommy wants you so hard it hurts. You want to give that to mommy don't you."

Josh gulped as he realized that while his relationship with his sister was on the dominant side apparently his relationship with his mother was almost entirely submissive. She gave him another squeeze, and despite himself he realized his cock was actually getting even harder, as if his body pumped more blood to it because his mother wanted it. He suddenly realized that his earlier thought, about how he had learned to unquestioningly obey his mother's voice extended to the bedroom. As sexy as he found her body, her voice seemed to be in complete control of his body. Even if he couldn't remember the history that brought him here, his body was apparently well trained to his mother's appetites.

"Good boy.", she said, as if praising a child. "Now, show mommy what you've learned about getting her ready."

With that statement she slid herself up your body, briefly brushing your overhard girth with her panty clad pussy as she slid up until she was directly over your face. She then pulled aside the material covering her waiting lower lips and lowered herself onto your face. You immediately found it impossible to breath through your mouth, and difficult through the nose as she completely covered your face with her ass and hips, but when you did inhale through your noise you were met with the overwhelming scent of your mother's sex - and somehow, despite your erection being beyond anything you thought you had, you got even harder. You could feel your mother reaching back and playing with your balls and cock - and she seemed to be in complete control of them, able to hold you from cumming while continuing to raise your arousal.

And then she tightened her hand painfully on your balls. "Don't make mommy upset - I've trained you better than this on how to ready your lover. Why are you bringing this on yourself? Mommy knows how much it turns you on to turn her on, so why are you hesitating?"

Realizing you hadn't been doing what she expected, and from this position there was little doubt of what that was, you began to use all the movement that her pressure on your face allowed you to tease and stimulate her. Your lust addled mind did allow you just enough thought to come up with a new rule you would enter immediately after you were finished satisfying your mother's sexual desires, which you were sure would lead to many other positions before she was done.
