What happens next?
Jake gets even more
Carrie left you alone as you were still struggling to wrap your head around what had started off this day. Your faithful girlfriend gave your roommate a blowjob and used his cum to grow until she now stood at a massive 6'3" tall. It was difficult to actually believe it wasn't a dream as she walked back in, naked and looking like an absolute goddess.
"Growing while we fucked was soooo insanely hot, wasn't it sweetie?" she immediately asked. She left the door wide open behind her as she walked to the edge of the bed and looked down at you. After a few amazing seconds of gawking up at Carrie you finally manage to answer.
"Fuck, it really was," you said.
"God I'm glad you agree!" she squealed, jumping up and down a bit. Her newly grown tits bounced and jiggled more than ever and were practically hypnotizing as you gawked up at her. Carrie clearly loved the attention, but after a few seconds of your stunned gawking she spoke up.
"I'm gonna go suck Jake off again then."
She said it so confidently, turning and walking right back out the door. No hesitation, she was going to give another man a blowjob, and didn't even think to actually ask you about it. Hell, she didn't even think to ask before the first one, and now here she was nonchalantly leaving for another man's cock.
You sat on your bed, trying to comprehend what was actually happening. Your girlfriend was going to your roommate's bedroom to guzzle down his cum so she could grow more for you.
Your thoughts were interrupted as you heard noises coming from down the hall. It took a second for you to register what the familiar noises were that brought you to your feet.
Carrie was moaning. Loudly.
You didn't bother getting dressed as you rose from the bed and walked down the hall. With each step your heart beat faster, until you came to Jake's wide open bedroom door.
Instead of walking in and finding your now impressively large girlfriend on her knees sucking off your asshole roommate as you expected, you found her naked on his bed. She noticed you in the doorway, her beautiful brown eyes locking onto yours as you took in the sight. Your girlfriend, on all fours, being fucked from behind. Through grunts and moans, she finally tried to explain.
"Don't worry baby, he promised he'd take it out in time to cum in my mouth, he said this was the only way he'd let me have more of his cum."
Carrie explained it all like it was normal. Like there was nothing at all wrong with the fact that she was letting your roommate fuck her right before your eyes. Meanwhile Jake kept sliding in and out of her, with no concern over the fact that you were watching them. Another moan slipped out from Carrie's mouth, followed by a yelp as she looked over her shoulder to your roommate.
"Oh fuck! Not so deep Jake, I'm still trying to get used to your size," Carrie said, returning her attention to you. "C'mon baby, come join us," she begged.
