Amazonian Futa

With just a click of her fingers, her body began to balloon with muscle, growing taller, larger and stronger with every second. Her delicate ballgown tore like paper against the might of her swelling musculature. The floorboards creaked as she stumbled forwards, curling in as her traps became huge, rock-hard pillows, her lats massive wings of power.

With a roar, she hauled herself upright, all three metres of muscle. Her fist, one and a half feet across, came crashing down on her bed, crushing it into tiny splinters that couldn't even break through her leathery skin. Her body shook as huge, rumbling laughs bubbled up from her throat.

She was huge! She could hardly believe it, but seconds ago she had been the frail princess, small, weak, and completely ignored. Now look at her! She flexed into her mirror. Not only was she bursting with strength, she was also hot enough to make any model or bodybuilder fall at her feet and worship her. Her sister wouldn't be able to resist her now.

Right on time, Elsa stumbled through the doorway. "Anna! I thought I heard... something..."

Anna turned around, flashing her with a sharp grin. "Hey Elsa. What's up?"

The queen looked as though she might faint any second from the sight of her. "Anna? But you're-"

"What, are you speechless? Aw, I'm glad to see you too." With another click, a huge, baseball bat sized dick sprung from her crotch, standing at attention. Her cantaloupe-sized balls gurgled, her hyper-virile seed itching to be released into Elsa's virgin pussy. "And so is this bad boy."

Elsa was drawn in closer, the musky smell of her sister's throbbing member almost too much to endure. It gave her a feverish heat, a flush spreading across her skin, her mouth watering at the mere thought of the monstrous cock sliding down her throat, or stretching out her insides. "God, Anna, you're so damn hot!" She didn't know who was talking at this point. A haze of lust had taken over her mind, pushing her to rub up against her sister's naked body.

Her hands wandered across the veiny, leather-bound muscle, starting at her mountainous abs then working further down, past her groin and down onto her shaft. Her fingers delicately danced across it, icy cool touch at odds with the tremendous heat it was giving out.

Anna smiled down at her now tiny sister. She placed one massive hand on Elsa's head and positioned her at the head of her cock. "Now, suck."
