Waking up with a blowjob

Drifting off to sleep after multiple orgasms with your stunning growing girlfriend was likely the best way anyone has ever went to sleep in the history of humanity. You were exhausted and slept through the night comfortably, only waking up when you felt something tickling at the base of your cock. Groggy and still half asleep, you looked down to see Carrie, gazing up at you with those big brown eyes of hers. Naked as can be and with your hard cock pressed against her face.

"Morning babe," she said, running her tongue up the length of your shaft after. You were certainly wide awake now!

"Well good morning to you too," you said, letting out a tiny gasp as she licked your hard cock once again.

"I want to grow more. Pretty please cum in my mouth baby," she said, your cock disappearing between her lips immediately after. You didn't exactly need the encouragement as your girlfriend worked to please your cock, and with how sensitive your morning wood was, you knew it wouldn't be long before Carrie got her wish.

"What...what part are you gonna grow?" you finally managed to ask. Carrie bobbed up and down on your cock for a few seconds, stopping to free your cock from her mouth. Carrie flashed a seemingly innocent little smile up to you for a quick second, not saying a word before she returned to sucking your cock. Your mind reeled with possibilities as Carrie brought you closer and closer to the edge. She clearly had something in mind, but what was it!?

Muscle? Height? Tits? Growing all around? Would Carrie want something even more surprising?
