The Precise Moment Clothing Fails [WM]

The green haired futa's eyes were devious as Lily took the potion and drank the contents. Nefer couldn't help but get a good look at her sisters new cock as she stood. She was slightly jealous to see that hers was a bit bigger than Nefer's. But that didn't last long as her eyes quickly went from devious to wide with surprise as what was left of Lily's clothes began to groan in protest before starting to rip. "What the?.."

Nefer's cock throbbed powerfully, drooling precum onto the floor beneath her as Lily rapidly swelled in overall size before her. And what a sight it was. Before, Nefer had been aroused. But, after seeing this? She was beyond horny. And a little scared.

Finally, Lily's growth seemed to stop when she reached around 10ft (305cm) tall. And Nefer was now eye level with Lily's proportionate cock in her face, with heavy gurgling balls swinging beneath. "So... big..." She muttered.

However, Nefer flinched out of it when Lily began to speak to her. "P-Potions?" She stumbled over her words. "Y-Yeah, there were a ton more potions all over the place. There was... at least 50 in the room that looked like an alchemy lab..." Nefer pointed to a side room. Lily's cock drooled a massive glob of precum onto the ground causing Nefer's eyes to go even wider. Of course Lily had to get a potion that turned her into a mini giantess right after they both got a cock...

As she looked down at her older sister, the new perspective was definitely doing something for her. Seeing Nefer at such an adorable size, compared to a few inches taller than her, was something she certainly wasnt complaining about. She glanced at the door Nefer pointed to, half listening and not really paying attention as her gaze traveled back to her cock swinging just beside her sister's face.

She bit her lip as she listened, "Uh huh...right..."

While tempted by the idea of all those wonderful potions just waiting to be tested, she started to get another idea in her head.

A glob of precum dripped from her cock as it shuddered, and started to become stiff and erect. She bit the tip of her index finger and held her shaft with her other hand, "Sis...do you think...do you think you could help me out with this?
