Your mother, definitely not sleeping

"Ohh, fuck" you hear your mother whisper, as the dildo descends another inch into her ass before bottoming out. If you weren't standing there gaping like a fish at the sight with the door open you never would have been able to hear it, but you do. And it is glorious.

"Mmm" she lets out a satisfied hum as she pulls it back out again. She is on her stomach, tits flattened against the bed while her ass is in the air, propped up by her knees. Her right hand is slowly withdrawing the dildo from her guts as her left hand is doing slow circles of her clit. You can see her pussy *dripping* and soaking her right arm, which is going between her legs to manipulate the tool currently in her.

The first thing you think is 'I'm bigger than that thing', the second thing you think is 'wait why the fuck was that the first thing to come to mind' and your third thought was silenced by the *pop* of the dildo as it is fully retracted.

You're still dangerously hard

You're also completely frozen, mind blanking on what to do or say, every neuron focused on watching your mother lubricate the bright pink toy with her own *copious* juices, running its full length between her fat lips, down to her clit, and back up again before easing it back into herself with a satisfied sigh, pushing it all the way to the base once again.

"Oh".

You can see her clench, hard. She wheels around and, gasping hard at the sight of you she, dildo still in ass, grabs the blankets she was laying on and throws them around herself to protect her modesty

Or tries to, at least. She grabs the corner of the blanket she was sitting on but unfortunately she was sitting close to the edge of the blanket and didn't think to grab the other, longer, side and only manages to cover one nipple with the short end she has.

She rectifies this by using her arm to cover her other one, mashing her breasts together and against her body, making a scene possibly more enticing than if she just let it hang.

You are both once again, frozen

...

"Sorry, I'll come back lat-"

"T-This isn't what it looks like! I was-"

You both try to speak at the same time, then pause, try to speak again and pause again, too polite to just speak over the other person and dragging on the awkwardness

Your mother gets up, you might have been able able to spot a furious blush if she wasn't already redder than usual and flushed from forehead to tits, and she rushes towards the door, likely to try and close it, with a blanket just barely protecting her upper half from being seen. You get a good look at thick lower body though, as she stumbles.

A lot of things happened in that moment she stumbled. The cause of it was the half-forgotten piece of gnarled silicone sitting firmly in her ass, slipping out onto the floor. Her eyes rolled back in ecstacy and she falls to the side, twisting her ankle and landing in a rough, spasming heap on the ground, the pain only adding to the sensation.

With her eyes rolled back and her teeth clenched, one hand grips the fat lips of her vagina, as if if she squeezed it hard enough between her fingers it would stop the humiliation of orgasming on the floor from anal stimulation right in front of her son, while the other hand roughly squeezed a tit of its own accord.

"Ahn! F-f-fuck!"

She writhes.
