Use it

Edward flexed his new muscles in the mirror. I’m ripped, he thought. He wondered, how many women he could conquer with a body like this. He grinned. Then his eyes fell on his penis. It was still small. Edward had measured it once. Three inches. Laughable. He frowned.

Edward uncapped the marker and placed it against his thigh. He hesitated. What if it didn’t work? His hand shook slightly. He exhaled sharply and wrote: BIG COCK.

As the final letter was written, Edward wrapped his hand around his penis. He felt the veiny cock grow inside his hand, until his fingers only barely met. "Shit!"

Edward's breath came in short bursts as he stared down at himself, his half-hard cock dangling between his knee-caps. “Jesus!”, he called out, instinctively beginning to rub himself. He couldn’t help himself. The sheer novelty of sensation was overwhelming.

His hand, once too large for his own equipment, now struggled to contain it. He squeezed experimentally, feeling the unfamiliar heft, the way his fingers sank into warm flesh. Precum slicked his palm as he stroked, watching in the mirror as his reflection, this new, sculpted version of himself, responded in kind. His abs tightened, his thighs flexed. He’d never felt this kind of raw, visceral pleasure before.

For a moment he forgot the marker, leaving it on the sink for the time being, while he enjoyed the fruits of its labour.

Edward’s hand moved in slow, deliberate strokes, the pleasure overwhelming him, as he imagined a bimbo suckling on his massive tool. He bit his lower lip, as his penis, hard as a rock and pointed high towards the mirror, finally shot out its load, sprinkling its owners face in the mirror with his own white cum.

Luckily most landed on the mirror, and Edwards body remained mostly unscathed. He grabbed a towel to clean the mirror, leaving no trace of his self-pleasuring behind.

Now, once again, Edward turned to the shower, ready to clean himself, though he knew he had to give up this body of his, at least for the time being.
