... just can't stop, but warn her.

"I'm gonna cum ..." You grunt, feeling the orgasm approach.

Cat stares at you in the mirror, eyes like saucers, mouth open both in shock and in a stifled grunt, holding her breath.
It's just an istant, but you both know what's gonna happen, and none of you has really the willpower to stop it.
A sort of of mutual agreement.
Very welcomed, as it is not as you would be actually able to stop now, even if she had said no ...
In fact, rather than a warning (which would have required you to grasp the gravity of the situation and it's concesequences...), yours was a simple statement, a plain description of the event occuring.
Fortunately for you she'll probably never know about that...

Naturally, like she's not the struggling woman of a minute ago, like she's not Miranda's mom anymore, you let her wrists free, able to brace herself to the sink, and grab her by her soft hips.
Staring right into each other, sudden makeshift lovers, you thrust deeper that you can, flesh clapping resoundingly in the empty bathroom, grunting at the unison.

"Fuck..."

"Fuck meeeh ..."

Your legs almost cave feeling the first thick spray of cum finally being released into the snug cavity of her womb.
At the same time the walls of her spasming pussy, almost like reacting on their own will, a will so primal and inconscious as to know no shame to be filled to the brim, starts to contract visciously, seemingly in the attempt to milk your balls dry.
A little, eager mouth, thirsty of your cum that you sate with ease, given how the your have been teased for the previous hours.
And to be honest, you have been too under a dry spell in the last months.

The initial drive of your thrusts subsides, yet Cat knunkles turn white around the spigot, as you keep pounding her, pushing all air out of her lungs, and all yourself into her belly.
You squeeze her plump cheeks, parting them with your thumbs, streching the darker skin of her clenched anus teasingly, a white trace oozing out of her still convulsing sex over your shaft as you slowly draw it out only to tuck it back in again.
Shuddering, she glares indecipherably at you, still hard and deeply rooted in her, but spent.

As you gradually come back to your senses, you take notice of the shocked expression drawing on her face.
In afterglow you don't get immediatley why Cat seems about to be freaking out ...
And then it strikes you.
You've just come inside your crush's mom.

Shit ...
