In a brief moment, Jeff saw the locker rooms with the surprised naked ladies flashing by before he was dragged back into the open air, across the beach until the guys finally stopped at some distance from the building they took Jeff from, making sure they weren't being followed. Jeff met their gaze one by one as he was being passed around for them to have a better look. "Not a bad catch in all", one guy said, "now what shall we do with it?" Another guy grinned:"Did you see their faces when we ran out of there? Let's one-up that and wear this thing in the open, that oughta draw a few stares." Amazed at his daring, the other guys agreed. He pulled off his swimming trunks and pulled his feet through the leg holes of the suit, barely managing to do so as it was way too tight on his huge body. "Damn this thing is squeezing my nuts, couldn't you have stolen something that doesn't go halfway up my asscrack?", he laughed. For Jeff, however, this was no laughing matter as the stretching actually hurt a lot - he wasn't made for this kind of physique at all. Around the groin area it was too tight and around the chest area too loose, and overall this guy's muscle mass was almost completely visible through the fabric.
Suddenly, Jeff felt his body slinking back to a more natural and less painful state, as if he was now made for this kind of person. The reverse was true, however: his wearer was conforming to him! The crotch molded perfectly into the suit's bottom, of which the rear now perfectly covered a rather small but round butt, and the chest section was starting to regain its usual tension. His wearer was now being stared at by the other guys, who gaped in awe at him - now her. "...what?", she asked while still oblivious to anything being changed, not even noticing her voice. "D-d-dude...you're a chick...", one of them stammered and pointed at her chest. She looked down and indeed, her entire figure had changed. She hadn't even noticed that she had to look up a bit as her size had decreased by about a foot. She panicked as to what to do and said:"maybe it'll go away if I take it off again." She slipped back out of the swimsuit, much easier than originally getting in now, and stood there completely naked for a moment, nothing happening except for the other guys cheering at the naked girl before them. Somewhat irritated at this show of immaturity, she quickly put it back on and she asked them for ideas on what to do now. "Well", one of them answered, "the best idea would be probably to just bring it back to where it was, maybe that'll fix it. And if not, maybe the original owner knows more about this." She smirked and said:"Okay, and who's gonna return it? They'll see us coming from a mile away now."
"Why, you of course. As much as you hate it, your current situation allows you to go in there without anyone giving you funny looks, take off that thing and hang it back. If at all possible, without the original owner seeing you."
"And what do you propose I should wear afterwards then? I don't plan on showing half the beach my private parts."
"Don't worry, we'll go to the store over there and buy you a new one in the meantime."
Agreeing with this plan, she nervously set off back towards the locker room, to hang this cursed thing back and get the hell out - probably...
