Merlin lounged naked on his small twin bed. His half hard dick was tucked between his thin, hairy thighs, which were crossed and propping up an old black notebook. It was about the size of a short paperback, but it had no markings of any kind, except for an inside corner which had a small stamp that read "Property of ________". A name appeared to have been erased from the line.
Merlin tried to flip to the first page, but it wouldn't turn. He licked his finger, trying to grip the stuck paper, but no luck. He tried to wedge a fingernail between the pages, but he couldn't find a seam. Eventually he tried to pull the book open with all his meager, scrawny strength, but nothing. It might as well have been a brick.
Merlin gave up trying to force the book open with a huff, and started studying it, looking for a way in. But still nothing stood out except the nameplate.
Merlin smacked himself on the side of his head, and grabbed a pen from his desk. He wrote "MERLIN," and as if caught by a slight gust of wind the first page turned. In its center were two interlocking pentagrams within a circle of runes. But as Merlin tried to identify them, they began changing. The runes slowly became a different set of runes, and then they started spinning around the pentagrams clockwise, just as the pentagrams began spinning counterclockwise. The runes kept shifting, they were hieroglyphs and then Greek letters then Arabic script, they turned faster and faster, the letters and stars now just spinning blurs.
Then all at once they stopped, and in plain English the words around the pentagrams now read "Merlin's Grimoire."
"No
fucking
way," Merlin nearly shouted. He'd played enough DnD to know that a grimoire was some kind of spellbook. Eagerly he turned the page, ready to learn what invocations or rituals he'd find.
He was greeted by an unreadable block of minuscule text. Merlin adjusted his thick glasses and brought the book up to his nose. But the writing was so cramped it might as well have been scribbles.
Merlin found his phone in the jeans he'd worn two nights before, and after tossing aside a few dozen notifications pulled up a document scanning app and, turning on the flash, took a picture of the first page. He checked the photo, zooming in as close as he could, and could just barely make out the first sentence, "The eyes, once cleared by spinning stars of mirrored revelation..."
Merlin grinned, satisfied with his ingenuity, and flipped to the next page. He figured he could scan the whole book then blow it up on his nice monitor, so with another flash he took another picture. But before Merlin could even reach for it, the grimoire flipped to the third page by itself, and without pressing a button his phone took another picture. Then again, but now the document scanner app closed and the front facing camera turned on. Merlin just had time to see his surprised expression on screen before the screen flashed in time with the back light. The pages began to turn faster and faster, the flashes of the camera quickly becoming strobe lights, and between the flashing screen Merlin watched his own look of amazement as if in a low frame rate movie, his reflective eyes seeming to glow.
Just as Merlin's phone became almost too hot to hold the last pages flipped, and with a thunk the back cover shut the book tight before it disappeared in a puff of scentless smoke.
"Holy shit," Merlin laughed. He checked his phone but it seemed to have shut down. He turned it on, and when the screen lit up he laughed again. The fruit startup logo was gone; two pentagrams were slowly spinning in the middle of the screen, surrounded in a circle by "Merlin's Grimoire," which on the phone appeared more like a button. He clicked it.
The pentagrams exploded out in a strange technicolor static like nothing Merlin had ever seen. Slowly the static faded, and as Merlin's dick and balls nestled between his crossed legs came into view, he realized it was a camera app. There were no buttons, and if not for the thin static border around the screen Merlin might've thought his phone had simply glitched out.
Merlin flicked the screen, and he realized he wasn't in a camera app after all--the video feed moved around at his touch like he was controlling a drone, or swiping around some kind of picture perfect virtual recreation of his surroundings. Merlin found it trippy to zoom out and watch himself playing with the app, his fingers matching his avatar's every movement.
Every object in the VR recreation was suddenly highlighted in a faint staticky glow. Merlin hesitated a heartbeat, then clicked on himself. Everything surrounding Merlin's avatar on screen began to fade away in colorful static, and then the avatar uncurled from Merlin's sitting position and extended its arms and legs out like the Vitruvian man as interlocked pentagrams appeared behind it. It was a perfect 3d replica of Merlin's body. He was able to spin it around and zoom in so close he could see his pores.
Merlin zoomed in on his favorite feature, his 7.5" cut dick. A bunch of sliders and boxes appeared around the edge of the screen. He picked a slider at random and pulled it far to the right. The model's dick suddenly grew down past its knees. At the sight Merlin's dick started to harden, and so did the model's, but while Merlin's real dick just curved up to just below his belly button, the model's looked like it nearly reached his chin.
As Merlin smiled at the image of himself with an enormous dick a small spiral appeared onscreen, where a camera button would usually be. The spiral began to spin, and Merlin pressed it. The spiral spun faster and faster and Merlin's vision seemed trapped in it, twisting and turning in time with the spiral. But then the screen went black and Merlin's surroundings crashed back into view, wobbling in Merlin's mind as if he'd just been spinning around in circles.
Merlin's dick began to feel warm. Even though Merlin had dumped a load in his fleshlight roommate not 10 minutes earlier, a drop of pre leaked out and into his belly button. He felt a pulse deep in his dick near the base, and then a pressure as if he really had to piss. The pressure grew almost unbearable but then it broke, and instead of pissing Merlin's dick started growing. His dickhead, already slick with pre, slid up his belly and ribs and chest.
