Step-mom in the Shower

You decide to take Claire in the shower. You've been wanting to tap that ass ever since she married your dad, and today you are going to do it. You make your way down the hallway towards the bedrooms. Your parent's master suite is at the end of the hall. Melanie's and Rachel's rooms are on either side. The bedroom door is shut but you open it up and stroll right in.

The door to the master bathroom is open and you can hear Claire humming to herself in the shower. The sound of the water masks the noise you make as you approach her. You open the glass door to the shower and jump in.

"WHAT THE HELL, DAVID!?!"
Claire is obviously surprised by your intrusion. She spins around, covered in soapy bubbles, as you gaze at her naked body. She moves one hand to cover her breasts and the other to cover her neatly trimmed pussy.

"Surprise bitch! God, you have no idea how long I've wanted to do this!"
With that, you grab her and spin her back around, facing the water. It sprays her in the face and she spits and sputters. While she's distracted, you hug her from behind, wrapping your arms around her and grabbing her breasts while your cock slides between the slick cheeks of her ass.
"Why you little motherfucker!", she yells.

A very poor choice of words, given what you plan to do to her.
"Actually, MOTHER, that's exactly what I'm going to do."
You bring one hand onto her back and bend her over. Then you grab a handful of her auburn hair and snap her head back up. This has the effect of forcing her chest and ass out. You release her breast and use that hand to line your dick up with her pussy. You slap her pussy lips with your dick a few times and she whimpers beneath you.
"Here we go, MOM."
You emphasize she's your mother, trying to drive the point home. She yelps as you slide your rock hard dick into her quivering hot box. Then you grab her hip, still holding onto her hair, and start thrusting away.

"Ah, ah, ah, ah!"
Claire starts screaming as you pound her from behind, the water splashing down onto her back. You thrust harder and deeper each time until your balls are slapping against her clit. You look down and watch your cock disappear into her backside with each stroke. Then you get a devious idea. You release her hip and move your hand into the crack of her ass.

"Wait, no ..."
When she realizes what you are about to do, she puts up some minor protest, but is too caught up in the royal fucking you are giving her. You spread her ass cheeks apart and rub your thumb across her puckered asshole.
"Ahhhhhhhh!"
Claire moans at this. You start rubbing her asshole a little harder, continuing to thrust into her pussy. Then, without warning, you jam your thumb into her tight ass.

"AH FUCK!"
Claire screams and bucks back against your cock.
"Oh, so you like that, do you MOTHER? Maybe I'll have to try that hole out next, huh?"
Claire glares back at you over her shoulder with a fearful look.
"Please, no ..."
You jam your thumb into her ass a little further. Damn, her ass is super tight. Your father must not have fucked her here.
"It's ok, bitch. I want something else anyway. Get on your knees."

You pull out of her pussy and it takes her a few moments to come down from the pounding she was taking. But, after a few moments regaining herself, she slumps down on the floor of the shower.
"Yeah, bitch, now suck my dick clean."
Claire looks up at you with disgust but opens her mouth. You grab her head and start pumping her face. You take some gratification in knowing she's tasting herself on you. You pick up the pace and really start fucking her face.
"Yes, yes, yes. Take it."
Her eyes snap shut and her jaw goes slack as she lets you take over. You piston yourself in and out of her mouth, pushing deeper and deeper each time.
"Deepthroat that cock!"
You push all the way in and she gobbles your entire cock in one motion. Obviously, she's had some practice with this. Now that her throat is open, you plunge in and out, again and again.

You look down, seeing the pretty face of your step-mom Claire, stuffed with your cock. Her tits bouncing on each thrust. Her freshly fucked pussy writhing on the shower floor and you can't take much more. You feel your orgasm building and get ready to burst.
