A week later, Jeff sneaks over

"Jeffy! You aren't supposed to be here when my step-mommy isn't, like, here! She said like, no boys!" She'd spent all month talking in her bubbly airhead accent and diction, and was finding it more difficult to turn it off at all. She set her phone down and walked over to him and leaned in for a welcome kiss. Elizabeth was lounging in her favorite schoolgirl uniform, a checkered yellow and black number that tied off between her tits, with a skirt that barely came down below her ass. The top was so sheer that you could see her nipples through the fabric.

Jeff kissed her back and cheekily said, "I just wanted to see my little Lizzie, aren't you happy to see me?"

Elizabeth shuddered at the name, but didn't correct him. "Oh baby, you hafta like, go now. If mommy sees you here I'll get, like the most big spanking evar!"

His eye brow lifted. "You will, huh? Well in that case, I'll have to make it worth it." He grabbed her and kissed her harder. She could feel his cock, already hard, pressing up against her. She felt herself go weak and wet all at once, powerless to stop him at all.

They moved quickly over to the couch, where he bent her over for an inspection. "What have we here? Lizzie isn't wearing panties? Naughty little girl, she is." He began rubbing at her clit just like her sister had done, eliciting a moan from Elizabeth as she struggled to hold herself upright.

"Is this an invitation? Do you want something from your daddy?" He positioned over her. She could feel her schoolgirl uniform riding up her stomach, her slit was sopping. The tip of his cock touched her pussy, and a tiny part of her knew inside that if he fucked her right now in her current state of mind, she was going to crack completely.

"Do you want this?" He asked, the implications heavy.

She hesitated the smallest fraction of a minute. "Oh gawd, please daddy..."

Her husband plunged into her, and she saw stars as an orgasm ripped through her mind like a tornado, shattering the last bits of Elizabeth.

Lizzie cried out in lust and primal need as Jeff pounded her little college freshman pussy. She felt her legs give way as Jeff grabbed her hips and jackhammered into her. She needed this, she needed it so bad.

"You've been a little slut, haven't you?" Jeff asked her as he fucked her.

She never would have let him call her a slut before, but she didn't care right now. All that mattered was his cock.

"Oh yeah, I've been a real bad girl, daddy. I need your cock!" she cried.

He kept pounding at her, waves of bliss and hormones washed through her mind.

"You stupid girls think you can just tease men all day and not get fucked?" Jeff grunted as his cock cleaved into her mind.

A small part of her mind cried out that something was really wrong. Why was he being so rough with her? Jeff was usually kind, gentle.

"Answer me slut, or are you just too dumb? Are you just your boyfriend's cum dumpter? "

Her mind screamed as another orgasm raged through her. She'd thought Jeff was her husband, but she was probably just too dumb to remember. Yes, she was just a dumb cock socket. A dirty little skank.

"Yes! Oh god don't stop daddy!"

He didn't stop, and with each successive orgasm, felt more of the old Elizabeth Hastings McDaniels, wife and older sister to Megan Hastings, splash away into the ether. She wasn't pretending to be Lizzie the bimbo girl anymore, she'd have to pretend to be Elizabeth McDaniels.

She felt Jeff cum inside her cavity, his hot load painting the walls of her tight little cunt. He crawled off of her and slapped her still reddened ass playfully. She moaned in delight and pleasure. He cleaned himself off and got dressed, leaving her to recover on the bed.

A few minutes later and she was able to find the strength to get up. Lizzie stumbled on her wobbly legs and felt herself squelch onto the couch, cum dribbling out of her cunt. She heard Jeff from the bathroom, "Baby, daddy has to go to work ok? I'd love to stay and fuck you for another round, but I got a job now, so I can finally start paying the rent again. Maybe you can come over sometime if your mom says it's ok. I'll fuck some more of your brains out, haha."

The high of their delicious fuck gone, her mind reeled. Jeff got a job? Shouldn't that mean she could quit... whatever it was she was doing, and move back in? Why was she living here again? She shook her head to clear her mind, as Jeff walked back in to the living room.

"But Jeffy, I... I thought we was like, living toge- toge- like, in the same housey?" She stuttered. She hadn't meant to speak in her airhead diction. That was usually just for when mommy was around. "I mean, like, wasn't wes like, married or something?" her eyes went a little wide and she put a hand over her mouth. Her fake yellow nails sparkling with rhinstones and glitter. She couldn't get rid of the thick accent.

Jeff seemed not to notice, he just laughed, "I don't think I'd marry a dumb slut like you, Lizzie. You're a great fuck, but I need a woman who's got something going on upstairs." Lizzie pouted, crestfallen and confused.

Jeff kissed her on the forehead, and grinned evily, "but if you want, we can do a little roleplay, you can come over and pretend to be my sexy little wifey. It'll be hot."

Lizzie nodded, figuring maybe all this fucky fucky was messing with her simple mind. "Oh, ok daddy. I'd like that super sexy fun idea. It would be like, so much fun!" She grinned, braces on her teeth glistening against her already straight teeth. Mommy had told her she needed them if people were going to believe she was only 19.
