Jake held his breath. The jock toyed with his phone, making a game of pretending to choose. However, Jake could see a faint line of concern on the big blond man's forehead. Was it possible he had never actually seen this message before and was wondering what, exactly, the options would do? 'Block' - would that block Jake's attempt to change him, or brick his own phone? 'Report' - would that stop the adjustment and tell whatever authorities were behind the watch's powers? Or allow them to go through with a mere note? Josh's finger moves slowly toward 'Block' - then, glancing toward the watch, quickly presses 'Sync'.
Sync - what did that mean? Did Josh now have control over the watch? Or something else? Jake felt a familiar warm sensation at his crotch. Warm - he was growing? But that meant...
"C'mon guys, quit yapping!" announced Liz, stretching a thin tape measure between her hands. "Let's see how you measure up!"
Josh's bravado seemed substantially deflated but he hooked his thumbs into his slacks and pulled them down, revealing a very sizable six inch semi-flaccid cock. Was it smaller than it should be for nine and a half erect? Hard to say, and Josh was never a grower. Liz, of course, was in heaven - the last time she'd seen Josh's cock it was a respectable five and a half erect. Now it was bigger than that flaccid.
Jake looked on as Liz nuzzled at her boyfriend's meat and it expanded larger, and larger.
When she was satisfied Liz stretched the tape measure along the top. "One... two... three... four... five..."
Josh seemed altogether too interested in the count to have not felt that cold shrinking sensation. Jake resisted the urge to pull out his own waistband and take a look, but shifting side to side there definitely seemed to be some heft that wasn't there earlier.
"Six, seven... eight..." Liz's ecstatic delivery didn't seem to have the desire impact on Josh - he was looking at how little dick there was past the line. She flattened the metal tip of the measure against his belly and pushed to get a little extra length, which just squeaked the head up to the nine inch mark.
"Nine inches on the dot." she said firmly. Jake looked over at Katie, who had both hands over her mouth in shock. Perhaps reasonably, given Josh's cock had almost doubled in size since the last time he'd gotten it out in her company.
"There's no way," she squeaked. Jake could see the idea of getting acquainted with that monster settling in and he decided to step in.
"Hey, it's a warm evening. I'm feeling pretty big myself. Come on Katie, let's show them how it's done." He put on a smile and slipped his own sweatpants over his growing erection. His girlfriend's momentary deer-in-the-headlights response to Josh's equipment gave way and she scrambled over to him after retrieving the tape measure. Jake willed every ounce of blood he had into his swelling erection.
Katie positioned the tape measure at the side of Jake's cock, pushing the tip into the flesh between package and leg. She looked up at him and nodded - as though saying 'You need all the help you can get'.
"One," she said, "Two, three, four, five" - if his gambit with the watch had gone to plan, he would already have won the rematch and Liz's affections would be all his, he thought ruefully. It *did* look larger than he'd set it to earlier; almost large enough to make him believe his suspicions about the effect of the 'Sync' were correct.
"Five, six, seven... eight..." A slight frown on Katie's face that he recognised as contradictory memories fought against the various realities the watch had brought into being over the past month. Wasn't Jake seven and a half? Or was it more like a foot?
Jake pushed into her hand insistently, and his generous cockhead nosed past the nine inch mark. Her uncertainty turned to glee as she carefully nudged a little more of the tape into the side and loosened her grip a bit on the other end. Jake's cock appeared almost nine and a half inches long.
"Nine! - nine and a quarter - almost nine and a half!"
Liz stormed over, eyes boggling.
"No way, you're measuring it wrong. Look - he's only ... uh..." Liz grabbed the tape from Katie and laid it flat on top of his cock. She left the metal clip flush to his cock head but he quickly put a finger on it and bent it up, pushing it a little into his belly. She looked up briefly, annoyed, but couldn't complain; she'd done the same thing with Josh.
"He's..." she stared at the result.
"Nine inches on the dot." said Katie. The two men looked at each other. At least they knew what the 'Sync' button did now. The process had harmonised Jake's watch-boosted eight and a half and Josh's app-augmented nine and a half into two pleasingly huge nine inchers.
"Mine's thicker," said Katie, grimly. It was true. The sync hadn't made them identical, just changed them to the same length. And Jake at nine inches was thicker with fatter balls than Josh at the same length.
"We didn't say anything about girth," ventured Josh, for the first time since messing with his phone. "We're the same, right? Does anyone disagree?"
"What do we do now then?" asked Liz.
