The group looked at the fountain, desperately thirsty, but uncertain of what weirdness might happen if they drank. Jon finally stepped forward and volunteered to try drinking first.
Jon knelt down beside the closest pool and cupped his hands in the water. It was icy cold, but very clear and looked completely clean. He lifted his hands to his mouth and took a sip. The water was cold, clean, and refreshing. It tasted amazing. Jon felt a tingle spread down his arms and through his body. As he watched in amazement, the cuts and scratches on his skin healed and the bruises faded away as though they had never been there. He felt the fatigue falling away from him as if he was discarding an old shirt.
Jon stood up and exclaimed, "Look, the water is magic! It's some kind of healing fountain!"
Excited, Brent and Athena rushed over to grab Stan. They started helping him towards the fountain, when Jon felt a strange pressure building in his chest. Jon reached up and put his hands on his pectorals, where the pressure was focused, when it started to intensify into an almost-painful throbbing.
"Wait!" called Jon, just as two unmistakable breasts started to grow out of his chest. At first they were fairly small, a-cups at the most, but they kept on growing and growing like two balloons filling up with water. Everyone else watched in fascination as Jon's chest expanded into two large breasts - perhaps dd-cups, sticking proudly four or five inches out from his chest, capped with large pink nipples.
"Oh shit," said Jon, trying to cover up his tits. As he touched them, he could feel them getting heavier. The nipples were incredibly sensitive, and his tiny pecker grew rock-hard with arousal. Embarrassed, Jon turned away from everyone else, trying to cover his tiny erection with one hand (but touching it just made him feel more aroused) and his large breasts with his other arm. A tiny drop of milk formed on the tip of each of his nipples. "Fuck, I'm lactating?!" Jon said, louder than he meant to.
The others paused, looking at Jon and then at Stan. Stan said, "Maybe I can try drinking out of one of the other pools instead?", smiling weakly in spite of his battered and abused body.
"I'll try one," Zoe volunteered. She walked over to the pool to the right of the one Jon had drunk from. "I'm okay with getting bigger boobs, if that's what this fountain does," she said.
Zoe knelt down and drank from the fountain. Just like Jon, the minor scratches she had suffered faded as if they had never existed. Stan, Athena, and Brent watched her intently for the next few minutes. Zoe started to feel uncomfortable, and suspected that the three of them had just found an excuse to stare at her small, perky breasts, when she felt a pressure building in her crotch. She gasped in surprise and reached her hands to cover her pussy, just as she felt her clitoris starting to grow. It swelled and thickened, pushing forward out of her vulva, getting bigger and bigger. Within moments, it was as big as an average-sized penis. Zoe turned away from the others and took a peek at it. It was changing in shape, too, and looked unmistakably like an uncircumcised penis rather than a giant clit. It kept on growing, too - the shaft thickened and spread out much wider than the top of her pussy lips, and it got longer and longer. It didn't stop growing until it was at least ten inches long and two inches around. Zoe looked up and saw that Athena had walked over beside her, and was staring in open fascination at her new cock.
"Holy shit, it's almost as big as Brent's," Athena said.
Zoe tried to cover it up, but the slightest touch sent a shudder of arousal rushing through her body, and the penis started to harden. Athena noticed that there was no sign of a scrotum or testicles underneath - the rest of Zoe's pussy sat intact where a set of balls would normally hang, moisture glinting faintly around the lips. Zoe tried to cover herself again as her cock grew even larger with its erection. Soon it stood proudly out from her groin, eighteen inches of thick, veiny meat, throbbing and pink.
Athena looked at Jon, and said "Sorry Jon, but your little sister has a bigger dick than you do now."
Jon, who had been preoccupied with his own large, lactating jugs, hadn't been watching Zoe. He looked over and saw his sister, red-faced, trying in vain to cover the massive wang that was bigger and longer than her forearm, and felt his own face flush in embarrassment.
"Why don't you try drinking from this pool," suggested Athena, "Maybe it will help fix your... problem."
Red-faced, Jon walked over and took a drink from Zoe's pool. The water tasted good, but nothing happened even after he waited for several minutes. Athena made him stand with his tiny erection visible to everyone else so they could see it change, but it remained exactly as it was. Droplets of milk slowly dribbled down from Jon's large, firm tits, and whenever he tried to wipe it away, he felt himself get more and more turned on.
"Maybe you can only benefit from one pool," suggested Stan. "I think I'll try drinking from Zoe's, if that's okay."
Rolling her eyes, Athena helped the bloody and bruised Stan over to Zoe's pool. He drank, and laughed in delight as his body healed almost instantly. He stood up, reinvigorated, and Athena made him turn around so they could see what happened to his average-sized penis.
"I feel something," said Stan, and everyone watched in amazement as a small bump formed beside Stan's cock. Slowly, a second penis, identical to the first, grew out of Stan's crotch. The first penis shifted slightly to the left to accommodate the second, and both quickly grew fully erect. Stan gingerly touched both of his average-sized erections and shuddered slightly with arousal.
"That's not what I thought would happen," said Stan.
Athena said "Since I don't want to grow a cock, and I don't need bigger boobs - or a second set of them! - I think I'm going to try my chances with a different pool."
