The two horny teens quickly looked for a more private venue. They found it several streets down at a transit station, where they quickly entered a bathroom together and locked the door behind them.
Emma sat on the toilet, not exactly glamorous, and blushed deeply with a giggle. "Ty, look..." She gently rubbed her hands over the massive swell of her chest. "I'm still growing!"
In the time since they had started to look for a 'private' place together, Ty had sped up Emma's breast inflation. The taller nerdy blonde girl's jean jacket could barely close over her substantial tits now. She tried to pull her jacket shut, but her boobs were just too big. So she took off her jacket and threw it over a nearby trash can. Now the sheer size of her chest became apparent. She was been a fairly willowy and skinny girl to begin with, and the firm tightly blown up DD cups under her thin blouse were so huge they were pulling her top up around the middle of her torso. Emma gasped, as did Ty.
"You're huge..." Ty gulped, blushing deep red. He was sweating.
"Ty... come here." Emma beckoned him. They could both see her nipples straining under her shirt, pointing and perky. Wanting.
Ty drew close to his incredibly busty new girlfriend, she stood against the wall. He smiled, she smiled. She took his hands in hers and gently placed them on her expansive tits. The boy barely moved, pressing down gently, and smiled as the tight breasts bounced back at his press. And they held that position for a few moments, during which Ty grew harder as he could actually see and feel her breasts expanding under his hands. Her nipples growing bigger, longer, her shirt getting tighter.
"Here." Emma whispered, and reached for the bottom of her shirt. She raised it, slowly, watching Ty's awe, and pulled it up enough that he could see the big naked growing tits underneath.
Ty held his hands under her breasts, marveling at their silky smoothness, and still she swelled. Ty looked at Emma, now panting and sweaty like himself, and she raised her shirt enough to show a bit of areola. Dark brown, tight, and beautiful. Ty touched the slightly rougher portion of her nipple and watched as they got goosebumps. Emma threw her head back against the wall and raised her shirt enough to show full nipple. Big and engorged. She was up to a round triple D. She had gone from honeydews to small watermelons, with an inch long and pert nipple capping off each beautiful swell.
"Please... do something to me." Emma sighed.
