Welcome to the Show, Twilight

Twilight slowly stirred, shifting her wings before she realized she was awake. She surged to her hooves before sitting down, looking down at her body.

There it was. A sheath was now far down on her stomach, almost between her legs. It looked… it looked big.

Bigger than Shining Armors.

Twilight licked a fang nervously, shifting her wings before she reached to touch it with her right hoof, giving it a poke. It felt… real. She could feel her hoof on it.

It felt odd.

Not bad. Not… not entirely unlike when she got her wings. She suddenly had these parts she didn’t have before, giving her sensations she had never felt before.

She frowned and started to slowly stroke it with her hoof. A swelling motion made her gasp softly and she looked down at her sheath as it almost seemed to grow outwards. The purple tip started to poke out.

Swallowing, Twilight ran her hoof along her sheath, her cock quickly growing and hardening as it slid out of her sheath, reaching full size.

“M-master? Wasn’t it meant to only be as big as if I had been born a stallion?” she asked as she looked down at her large cock. It wasn’t Princess Celestia size or even Spike size, but it was larger and thicker than her brothers. Or her fathers or Rarity. Larger than any earth pony she seen even.

As big as that Minotaur toy PF made.

“You are,” Master agreed as he flashed into reality, “If you had been the size of a normal mare, your size had been matching your brothers fairly close. But you are not the size of a normal pony and the rest of your body scale to match.”

That… that made a lot of sense. Just something she hadn’t thought about.

Twilight slowly ran her hoof up along the cock softly. It felt nice, but not absolutely amazing. It wasn’t until she got close to the tip as she gasped and shuddered. Oh, that felt nice. No wonder guys liked it.

She paused, “Master… what time is it? Am I late? I need to get dressed!”

“There is still an hour until you planned to meet your friends,” the diamond answered, “And if you wished, I can move your clothes for the day here.”

“Y-yes please,” Twilight said and then slowly stroked her cock again, shivering as she touched the tip.

She now totally got why stallions loved blowjobs so much. The thought of a muzzle around her cock…

“M-master?” she asked and frowned, “How… how do I make it go back down?”

“The same as any stallion would,” it answered, “By finishing or by waiting without further stimulation.”

Twilight hesitated and then closed her eyes, moving her hoof away from her cock as she started to breathe slowly and deeply, doing her best to think unsexy thoughts.

Her cock on the other hand didn’t want to cooperate and throbbed for her. Blushing, Twilight looked down at her cock.

“Down, damn you!”

It had little effect so she sighed and started to run her hoof along her cock instead, closing her eyes with a small moan. Fine, the other way then! She couldn’t trot around with her cock out!

Stroking firmly, Twilight moaned and shuddered, panting softly as she thought about Applejack, the feeling of being above the strong earth pony. She could do it for real now, without a toy, to feel her around her cock.

Making her moan out her name.

Panting, Twilight stroked faster, her pre cum making her cock slippery. O-oh Celestia!

Crying out with a moan, Twilight gasped and came, shooting her seed over her hoof and the stone floor.

Twilight gasped softly and relaxed slightly, trembling as she opened her eyes again, “T-that was way easier than normally… wow s-stallions has it easy.”

Working to get her breath back, she brought her hoof up to her mouth to lick clean, she looked around to find that her clothes for the day had been laid out already.

Not a lot today. A set of four thigh high white stockings and a medium sized silvery buttplug.

Not too bad.
