Use Transmutation on Marcus

You felt the energy swirl within you and the spell written across the page glowed, calling out a siren’s song.

Transmutation…

Looking over at Marcus, your mad curiosity won out over your conscience, the words escaping your lips seemingly on their own. The spell was in Latin, something you had no experience with, yet somehow your speech moved smoothly, as if the spell wanted to be spoken aloud. Your ring glowed, first crimson, then purple, a small inferno of melding colours that stretched out and found the sleeping form of Marcus. Soon he was enshrouded by the energy, his sleeping form beginning to rapidly change before your eyes.

You wondered if he would make for as attractive girl as Chloe.

But then something changed, you could feel the string of words that make the spell falter slightly, the energies changing in a way that you couldn't control. Marcus let out a decidedly feminine moan, and his body began to swell and soften in different areas, yet as the mist of energy cleared you saw that you had partially failed. Marcus had largely became female, but the erect dick that stood proudly showed that it was ultimately a half measure.

Marcus, or at least the being that was once Marcus, gasped awake, breathing heavily in his new form. “What….what’s ….happening?” Hands explored the new body, and at first you thought she was going to freak out at the sudden transition. But when she looked up at you, you realised something else had changed. “Cock,” she groaned, “need tasty tasty beautiful cock…”

She was up from her chair and on you in moments, holding you down with surprisingly strength and working to free your dick from within your jeans. A coo of delight escaped her lips once she saw the erect cock flesh and without preamble she sank down and went to work sucking you with everything she had.

Part of you was too stunned to properly react, but another part of you was excited to have futanari girl worshipping your dick like it was a sacred object. You lay back and tried to stifle your groans of pleasure, painfully aware that Tina was sleeping only a few feet away.

“Cum,” she said, taking her lips off your dick just enough to whisper around its head. “Gimme your sweet, sweet cum…”

She dove back down, the suction maddening. It wasn’t long before you felt your balls tighten and you emptied yourself deep into her waiting gullet. She locked eyes with you as she gulped down your load, not a single drop wasted.

When you were done she continued to lick and suck at your sensitive head, cleaning it thoroughly before resting her head on your lap, staring your softening cock flesh with wistful adoration.

“So gooood,” she sighed, content. “You taste so sweet, baby,” she grinned up at, drunk with lust and something else that you dare not name. “You’re such a good friend, Mike. Maybe you can fuck my boi pussy next?”

You were shocked by her words, but even more surprised by what happened next. A ripple went through the transformed futa, her body beginning to shift and reshape, her eyes glowing red-purple. She stumbled back from you, fell on her ass before the fireplace and then shifted back into her pevious male form.

He looked dazed for several heartbeats, then slipped back to unconsciousness. His breathing returning to the sleep rhythm.

You looked at your friend and then back at the book. You had failed your first attempt, but you supposed that it wasn’t a complete wash either. With a sigh you got up and went to work dressing Marcus and moving him back to his chair. You would experiment more with the spells at another date.
