Alex pisses off his girlfriend

Alex was a little too excited to try out the watch and his girlfriend could tell despite his best efforts to play it cool. Calling his bluff she starts teasing him,"Babe, clearly it must not work because last night you told me your cock was 6.5 inches long but the display on the watch says its detecting a 5.2 inch penis."

"It IS 6.5 inches you must be using it wrong! You can't even program a calculator so why would you know how to work this thing," Alex regretted the comment as soon as he said it but what the fuck right did she have saying something like that in public.

"Oh I can't figure it out can I?" She said with a devilish smirk. Alex started to grow concerned as she pressed the down arrow and the screen started to change numbers.

5.1 inches

5.0 inches

4.9 inches

"Sure you don't want to apologize Alex? And maybe you should apologize for lying about your dick size while we're at it"

"Fuck you bitch, there's no way that thing even works," Alex replied bitterly.

"Fuck me? Not with such a pathetic shrimp dick like you'll be having," She said while entering in a few button presses hiding the watch face from Alex.

Alex begins to feel a tingle in his crotch and has a brief moment of disbelief as he gets what feels like the worst case of shrinkage he's ever had despite the summer heat. He thinks to himself that this is impossible. I mean sometimes it just does that anyway when he's nervous, or cold, or has been running... But he can't help but get scared.

His girlfriend sees the look of concern on his face and starts to get worried herself, this was just supposed to be a joke after all this was not something that could really work. She figured he'd been lying about the size of his dick cause all guys do and 5.2 seemed like the right number but that had to be a coincidence. She hadn't even been paying attention to how small she had set the watch to. Looking down in horror she sees a message saying,"Cock adjustment complete, all changes permanent only one adjustment allowed per subject."

The screen flashes back to reveal her boyfriend's new penis size...
