It was hard enough when Aang reached manhood, his voicedeepening and strengthening shaking with power to stop conversations with a word. The idea of that man, that broad shouldered shaving man with his sister unnerved him a little. It was hard to see his sister as a woman, even though somewhere deep down he knew that she was grown, that the faint resemblance to their mother had grown as they aged. It wasn't until her belly was swollen with a child that he saw her, though, really saw her as a woman standing next to a man, ready to begin a family.

They were grown, they were grown. It drummed in his head endlessly wandering through the small, half-built town they were struggling to create Republic City in. He sat by the river, head pounding, hoping to find some peace and only finding Toph Beifong instead.

With his mantra drumming in his head, the realization of her was sudden and painful. She wore a strip of green fabric tight around her breasts - which were obvious now, even when she wore loose fitting clothes. It was damp and stuck to her as she up ended a bucket over her head. It rolled over her, her dark hair even darker wet, and a bright contrast against her skin. It fell down to her back, and the water rushed onward, over the narrow waist and wider hips, though still far slimmer than Katara's, they were no less feminine. No less adult.

Her feet were just barely in the water, and he suspected she only allowed that because of how muddy and firm the beach was. She put one foot on the drier shore, higher up, and cocked her head. "Sokka? What are you watching for, you perv?"

"You look grown up."

"I am. Thanks for noticing," she said dryly. "I'm twenty, you jerk."

He shrugged. "I guess, but you look grown up. I was just thinking of it, because of Katara, you know?"

"I look grown up?" She jokingly covered her breasts with her hands. "I knew you were a pervert."

"Shut up." He splashed her. "What do you think Katara's gonna have?"

"A waterbending girl." She came and stood next to him. "Come on. We've got grown up things to do."

"Now who's the pervert?"

She yanked his wolf tail. "Shut up. Let's go build a city."
