Stephanie leapt to her feet in the hot tub, holding her huge cock with both hands. She panicked for a moment; obviously she wasn't able to pull it off, and that seemed to be making it harder anyway. Her bikini was far too skimpy to hide the massive member, as it was designed to provide the bare minimum coverage of her body to be allowed on the school swim trip in the first place.
She was so freaked out by what was happening to her that it took her a minute to tune in to what was happening all around her. Stephanie looked up and realized that everyone was staring at her, and most people were muttering things to each other like "Is it real?" or "Is this some kind of a joke?"
Stephanie realized that she needed to get out of here in order to calm down and deal with this rationally. She climbed out of the hot tub and headed for the ladies' change room. About halfway there, however, strong hands gripped her arms and half-led, half-dragged her away. It was Mr. Wong, one of the supervising teachers, and he looked furious. He pulled her to a door near the lifeguard station, opened it, and shoved her inside.
"You two are in serious trouble!" he shouted. "Now get rid of those things before I come back!"
He slammed the door, and Stephanie looked around. It looked like she was in a first aid station. There was a small cot, a couple of chairs, and a large white cabinet with a red cross on the doors. Biff was also sitting in the room, and he had tears running down his face. It looked like he was completely naked, and he had one arm across his chest attempting to cover what looked like a huge set of tits. His other hand was thrust between his legs, covering his groin.
"Holy shit!" he said, as he saw Stephanie's huge cock. "Did you get those texts about a curse, too?"
As the initial confusion and embarrassment fell away, Stephanie remembered the strange texts she had received earlier. "Right!" she said, "is that what happened to you too?"
Biff nodded. "I can't remember the phrase to undo it, though, and Mr. Wong won't let me go to my locker to get my phone."
Stephanie said, "That's easy, it's un.... wait a second, you're trying to trick me!"
Biff's eyes widened. "No!" he said.
"Yes!" Stephanie replied, "you just tried to make me say the phrase first, so you could win! Now that I know this curse wasn't bullshit, I can think of some pretty sweet things I could do with it. I'm going to put up with this longer than you can."
"Fine!" said Bif, starting to panic. "You win! Honestly, I just need to know the words!" He clasped his hands in front of him in a begging position, letting his huge boobs flop down and revealing his tiny, bald nub of a cock.
Stephanie gasped and covered her mouth, trying not to grin. "Holy shit, I thought I had it bad!" she said, starting to laugh. "I was going to say that at least I had a bigger cock than you, but you barely have one at all!"
Stephanie turned her back on Biff and examined herself more carefully. Her cock was huge - it was probably 10 or 11 inches long, and so big around that she couldn't quite reach one hand all the way around it. She put her hand in her bikini bottoms to feel her balls, and was relieved to find there were none - she still had her normal vulva, complete with vagina and clitoris, underneath the huge dong. It seemed to grow out of her pubic mound.
Stephanie thought about her predicament. Clearly Mr. Wong thought that they were pulling some kind of prank; she could work with that. She found some small towels in the first aid cabinet, and tried to cover herself with them. Unfortunately, there was no way to hide her massive cock, at least when it was erect like this.
"How do you get rid of an erection?" she said aloud, to herself.
"Usually it goes away if you jerk off," said Biff, sniffling.
"Alright," said Stephanie, "let's see if my hand job skills work for me."
She started stroking her cock gently. Damn, that felt good. She felt her pussy dampening under her bikini bottoms. She stroked faster and faster, amazed at how good it felt. If she had looked, she would have seen Biff's tiny cock spring to an erection that was slightly bigger than the tip of his thumb. She kept stroking, almost completely losing herself in the feelings of pleasure, when suddenly she came. It hit her like a truck, and her hips spasmed almost uncontrollably. Thick cords of white fluid spurted out of her huge member, splattering across Biff's huge boobs and the wall behind him.
"Oops, sorry!" Stephanie gasped when she caught her breath. Biff leapt to his feet and started mopping the jism off his chest with wads of towels, his tiny erection standing forward. Stephanie noticed it, and couldn't stop herself from giggling again.
"Fuck you!" Biff shouted, trying to clean himself up. Stephanie stopped laughing and helped him clean up, but she couldn't wipe the shit-eating grin off her face. When they finished, most of the towels were sticky with her cum, and were useless for hiding her cock.
"Shit!" she muttered, then had an idea. Her cock had softened, and was hanging flaccid in front of her bikini bottom. It was only about six inches long now, and her pussy was still dripping wet. She pulled her bikini bottoms out and started trying to stuff the huge member into her vagina. It was painful, but it worked. Her pubic mound looked extra-big under her bikini bottoms, and it was painful to walk, but she could pass for normal if she could get some pants on.
Digging through the first aid cabinet again, she found a box with some old lifeguarding t-shirts in it. She also found a tensor bandage, and used it to bind Biff's huge boobs down to something that was almost concealable under a baggy shirt, if he slouched. Then they each put on a lifeguarding t-shirt, and Biff wrapped a second one around his waist.
"I'm going to outlast you on this curse," Biff hissed at her when Mr. Wong came to get them.
They apologized for their sophomoric "pranks" at the pool and were suspended from school for two days. They both managed to make it home, in significant discomfort, but the rumour spread that they had somehow smuggled fake tits and a fake cock into the pool and faked the whole thing. Many students had their doubts, but there seemed to be no other explanation that didn't involve magic, so they accepted it.
"This is no good," said Jon to Stephanie that evening. "I barely got to see anything. We need to plan the next one so that we can watch them get humiliated for longer."
"Alright," said Karyn, "but I'm amazed that neither of them has said 'uncle' yet. I wonder what happened in that first aid station?"
