Tom decided the best way to get the guys was the water trick but only a woman could get that close without suspicion. The cock thickened and formed a cocoon hanging on the rafter. A feminine form hopped out, with a basic suit on. He hear others approach so he primped herself in the mirror as the cocoon flowed back up. She decided to freak the girls out, they were wearing HS senior shirts. Decent tits and ass, but very shy. She intentionally expanded her tits in front of them to DD cups (nice and firm). They gasped, loudly. "Oh, Hi ladies! Do these look ok? Feel 'em" One girl extended her hand, in disbelief (they don't' just grow, do they?). They met the firm breasts and squeezed lightly. Tom already had a trail of liquid traveling down her arm, underside out of sight, to her panties and into her pussy for later use. The friend gasped again, causing the first girl to drop her hand. Tom then patted their asses in unison "Thanks girls, your bods are killer. Senior's rule!". Her fingers flowed into the second girl's pants and she bounced off. The girls changed, asking a hundred questions, not noticing their suits weren't theirs but copies that popped into existence.
A trail of boners tenting followed Tom as he laid out on the beach chairs near the men's court, again he made a point to exchange their water for his liquid form.
The guys were drenched as they couldn't get the ball the last few turns. Sure enough, shirts came off and they chugged water. Tom saw they enjoyed his new form, they were semi hard already. The game continued until they huddled to argue a call. The group went silent as they noticed one pair of shorts tent out a foot.
"What the fuck, cool off man!" "Think of your grandmother or something." "What? Oh shit, it's huge!" The other stared and felt their cock harden. "Not you guys too, come on. It's gonna be a sausage fest at this rate." "Not one girl will get near us."
The Center of the circle filled with tenting pants, Tom made up the difference to they all had foot long schlongs. The guys should have been concerned, but they were too busy staring and rubbing their tents. Before it gets any gayer, Tom gave them all the urge to urinate. Their bodies got leaner as the fat was converted to water. A flock of ten guys ran for the guys changing room, cocks leading by a foot. They forgot to watch the hot lady getting back up and following them, her tits deflating and her crotch growing out.
"Shit, that was close" they neared the door but their dicks telescoped out another foot, startling them all. Their underwear mercifully snapped and their shorts lowered to let the shafts out. They lined up near the urinals, three feet back, and shot. "Thank god, I was gonna burst." "Our clothes did burst you idiot. We're standing ten across with two foot cocks hanging in mid-air, what the hell happened?" The cocks went limp, a crescendo of meaty thuds sounded, as their now one foot dicks swayed between their legs. "Who cares, we're hung like horses." "Well horses are allowed on the beach, perverts with freaky cocks arn't!" "We sill have our shorts, who cares?" Tom had it covered, their balls swelled to bowling ball size as their last bit of fat. They immediately creamed their pants as gallons of cum erupted in their pants. "Oh for crap's sake, no one say anything, period." "We could have.." The sentence was cut off by the other guy's cock being used as a billy club on his leg, immediately sending him to the ground. "Can you keep it in your pants?" "Actually no, no one can it seams. We need something to holster these." "There's a store on the boardwalk, sweat pants will have to cover these until we can get home. Get a bag from the lockers and put them inside to hide them." They all rested their cock hoses in their bags and tried not to get aroused and headed for the store. Tom ran ahead to the store, making sure his long cock was covered with a speedo that had a one foot long pouch, soon to be a big seller.
