Klaus, her brother

Opening the door, Natalie was greeted by the sight of her younger brother, Klaus, waiting with a backpack.

The bespectacled eighteen year old was wearing sneakers, cargo shorts and a baggy black t-shirt with a video game character on the front of it, some scantily clad female warrior, posed to best show off her ample assets. He was scrawny for his age, far more comfortable in the library than in the gym.

"Klaus!" Natalie gave a squeal of delight and opened the door wide for her brother, accidentally clipping the edge of the door against her newly enhanced bust as she did. With a slight grimace, she put her hand to the affected melon and gave it a quick rub before she realized that her stiff nipples were more sensitive than she been before. Ignoring the tingling in her breast, she gave her visitor a wide smile and held out her arms. "It's so good to see you, little brother! Come on. Give me a hug!" She wiggled her outstretched fingers and then stepped toward Klaus, each excited footstep making her bouncy funbags jump in her shirt.

Klaus, for his part, was standing in stunned silence since his sister had first opened the door. He'd even thought that he had gone to the wrong door when he first saw the busty brunette, at least until she'd called out his name. Now, he still couldn't believe this knockout used to be his mousy sister. Her face was still the same, with a few small improvements, but the girl that he'd once teased for having mosquito bites for breasts was now sporting a gorgeous rack that rivaled the women from his video games. He barely registered his sister coming in for a hug before she was wrapping her arms around him and pulling him close, mashing those massive milkcans to his chest as she squeezed him tight.

Natalie was suddenly aware, as well, that her amplified breasts were an obstacle between them, making it harder for her to wrap her arms around Klaus. With an embarrassed laugh, she let her brother slip from her arms and stepped back from him so she could get a better look at him. "Today's been sooooo crazy, I almost forgot that you were coming this weekend! How was the bus ride?"

Klaus had a blush in his cheeks and and tried to look casual as he moved his bookbag in front of him, hiding the sudden tenting in the front of his shorts. "It was fine," he said, cautiously trying to keep his gaze on his sister's grinning face, though his eyes kept ticking down toward the deliciously deep cleavage exposed by her low-cut shirt. "You're looking really good, Nat." He couldn't bring himself to tell her that she was a total babe now, instead asking, "Are you doing something different since you moved to the city?"
