She's changed as well, but on a different level

"It's... too weird...!" Hannah sniffled, while hugging her arms even closer around her body, almost as if physically hurt - but also like she was actually trying to hide something about her.

"Hannah...?" Emma told her, as gently as she could, while walking up to her little sister and putting her hands on her shoulders. Instead of accepting the embrace however, the girl backed slightly away from her, and it finally dawned on her what had been looking so wrong about Hannah ever since she met her at the door.

"Just let me see it, okay...?" She insisted, still in her most gentle voice, while reaching for the front of her little sister's pajama. Hannah resisted a little at first, but then just kept on whimpering while she allowed her hands to be pried away from her chest.

"Oh, wow..." Emma breathed as she eventually managed to undo the buttons in her little sister's shirt, allowing the garment to fall open and reveal what was hidden underneath. Just like Emma herself, it would seem like her sister had suffered an unreasonable change to her body over the night - though for Hannah it had taken a quite different shape alltogether.

Instead of a cock, the 'poor' girl had apparently been gifted with an extra two pairs of tits, each of them nearly the same size and shape of her usual round and firm little A-cups, but positioned just underneath them on her slender chest. In some ways Emma could understand the girl being frightened, but at the other she couldn't help from enjoying what she saw.

"Oh, wow..." She repeated once again, while her fingers traced the outer curves of her sister's perky young breasts, watching as the nipples involuntarily grew harder at the featherlight touch. "Hannah, they're beautiful...!"

"Y-you think...?" Hannah just stared to her improved bosom, and couldn't help from blushing rather than continue her sniffling. She obviously didn't know what to say or think about her sister's acting, but found the gentle exploration to be strangely comforting. "B-but isn't it weird? I mean... they're not supposed to be like that...!"

"No, they're not!" Emma agreed, while marvelling at the feeling as she cupped each of the three sets of breasts in the palms of her hands. For some reason she found herself wondering more about what they would look like on herself, than worried why both she and her sister had experienced these changes to their bodies. "But, hell, they look good on you!"
