A surprise from your roommate

Several hours later and your sleep was interrupted. You woke to the beginnings of the sunrise peeping in your windows, and with Carrie's naked body crawling on top of you. Still half asleep and groggy, it took a second for your eyes to focus on the sight that was in front of you. Carrie flung the bed sheets aside, exposing your naked body and causing you to snap awake much quicker.

Carrie situated her naked body on top of yours, straddling you and looking down with a massive grin on her face. She didn't say a word, just looked down at you, and it slowly began to click that something was changing. Little by little, Carrie's frame was slowly blocking out more of the light coming in behind her. Weighing down heavier on top of you with each passing second.

"You...fuck are you growing more?" you blurted out as you saw your girlfriend expanding out before your eyes. Carrie didn't say a word, keeping the same perverted sexy smile on her face as she ever so slightly nodded her head. She reached a hand down and wrapped it around your cock, raising up in bed as she rubbed the head of your cock against her dripping pussy.

"I thought it was just from cum in your mouth?" you said, trying to understand just how Carrie was able to grow as she lowered herself down onto your now rock hard cock. Carrie slid down and engulfed every inch of you with ease, her head rolling back as she slowly began riding you.

"It is!" she said, gleefully bouncing up and down on top of you.

"Then how did you grow?" you asked, still trying to make sense of things as your hands went to your girlfriend's waist.

"Promise you won't be mad?"

It was hard to even fathom being unhappy as your stunning girlfriend rode your cock, while also somehow growing larger.

"How the fuck could I get mad at this?" you said as she slid down onto you once again. You felt your own orgasm building already and your fingers clenched down on Carrie's hips as she continued to slide up and down.

"I just sucked Jake off and had to come back to fuck you," Carrie said as she bounced on your hard cock. It took a second for you to truly comprehend what she had just admitted to.

Your roommate Jake. Got a blowjob from your girlfriend.

The scumbag mooch that missed rent half the time, left a constant mess, and was an obnoxious asshole to you and a sexist pig to the woman you loved.

And your girlfriend just sucked him off and swallowed his cum.

Your jaw dropped as you gawked up at Carrie, the news leaving you stunned and speechless. Her growth finally began to slow and Carrie looked down at you, locking eyes and no doubt able to tell that you were shocked.

"You said you wanted me to be huge, right? I thought it would be a hot surprise. Plus it's the only way you'll ever be able to fuck me as I'm actually growing," she said. Carrie argued her case as she sped up her movements, which was unfortunately too much for you to handle. Despite the news you just heard, your body was in heaven and begging for release, and you let out a moan as you felt yourself nearing the edge.

"Baby wait!" Carrie screamed, sliding off your cock and trying to rush to gulp down your cum. Unfortunately you couldn't hold back, your cock twitching as the cum sputtered out. Thanks to her suddenly stopping, your orgasm was nearly ruined and just a little bit of cum oozed out as your cock throbbed. Carrie scrambled down the bed and situated herself between your legs.

"Fuck baby, you came fast!" Carrie said, licking up the small bits of cum from your cock. She had you clean in the blink of an eye, quick to get up every tiny dribble of cum, and slowly eased off of the bed.

"You should measure me now. FUCK I feel big!"she said as she stretched to her feet. As you relaxed from your orgasm, it began to hit you just how big Carrie looked now. Everything about her had clearly grown, and you blinked a few times while trying to focus. Sitting up in bed gave you a better idea as you stared up at your larger than ever girlfriend. Everything about her was bigger than just the night before. Wider hips, thicker muscles, bigger tits. As you staggered to your feet, you gulped as you looked up at Carrie.

Up. At. Carrie.

Carrie had grown taller than you!

"Guess I should have warned you, Jake came a LOT," she said, giggling after. Carrie had a devious little smile on her face as she watched you stretch out the tape measure. You placed the end next to her foot just as you'd done the night before, expanding the measure little by little. Soon you hit Carrie's original height of 5'4 inches, just yesterday that was the top of her head, and now she had much, much more to go. You stretched the tape measure out nearly another foot, gulping before you said the measurement aloud.

"You're...six feet, three inches."

"Mmm, I like the sound of that," she said, her hands roaming down her naked body.

Just one load from Jake grew her that much? How much did the fucking bastard cum!?

You could barely believe what was happening, but Carrie was practically beaming right in front of you, clearly overjoyed at her massive growth spurt.

"God damn babe, Jake made me as tall as he is!" she said happily. Carrie turned around, giving you the first view of her expanded ass and affording you a better view of just how long her legs were now.

"Be back, gotta go clean up," Carrie said. Before you could question it, she was walking out of your bedroom door. Your girlfriend, now nearly a foot taller than she was just yesterday, walking naked right out the door without a care in the world.
