The Cobra Lady and Fred reached the office upstairs to find a heavily turned on Gretta lying seductively in the corner. The male crocodile took one look at the female he had once lived with in confinement and gasped in shock.
"M-My God!" Fred took a curious step forward. "Gretta! What's happened to you?"
The giant crocodile lady grinned slyly and waggled her finger come hither. Fred stared up at the snake lady and she giggled. "I think she wants to show you."
Fred stared in shock and carefully approached Gretta. He looked at her in awe and examined her form up and down, pausing on the good bits and wondering why this body aroused him so much.
"You're so big..." Fred gulped.
The male yelped as Gretta giggled and playfully grabbed him by the midsection, hoisting him off the ground to writhe in her hands. She stared at him hungrily and her fingertip began to brush under his tail gently, the hard claw sliding across his groin scales. He stopped struggling, his breathing heavy, but he was clearly terrified.
"Don't worry, little crocodile." Gretta said sweetly in her husky voice. "I might be huge and powerful, and you might be so small and helpless, but we're going to fix that soon."
"Oh...oooh!" Fred smiled slightly, relaxing as Gretta's touch began to stir his twins inside. "You mean... uh... this is Todd, right?"
"Oh yes. And soon all of us will be like this."
"Oh God!" Fred gulped. He felt his erections starting to rise. The tips began to push from his inner pocket.
"That's right, baby." Gretta smiled sweetly, watching as the male croc in her hands began to show reptilian wood. "All those years we were next to each other and hated each other. I couldn't imagine ever caring for you, but you're going to make a damn sexy crocodile man, aren't you?"
"Y-Yes!" Fred blurted, twisting his head and gasping as Gretta stroked his cocks under her fingers. "Yes! Just... just as big and sexy as you. Oh God, Gretta! I think I love you! I-I want to be your mate!"
"Ohh, Freddie!" Gretta trilled, giggling. "It turns out you're such a gentleman, huh?"
The cobra lady watched this quietly from the darkened corner beside the office door and found her new nipples poking out in excitement. Embarassed slightly, she quietly slipped into the manager's office to find the giant boa constrictor and Todd talking.
"Oh, hey, scales!" Todd smiled, reaching forward and embracing the tall lean snake in an affectionate hug. She smiled and blushed.
"Hey, creator." She said sweetly.
"Okay, ssssso we've got thisssss figured out." The boa sat up awkwardly, cramped in the room at his giant size. "He'ssss going to the janitor'ssss room where the water valvesssss are. He'sssss gonna dump some of the fun sssstuff into the ssssysssstem, then trigger the fire alarm. We don't want the othersssss to ssseee usss jusssst yet."
Outside the office, the rumble and groans of pleasure began as Gretta and Fred began to get heavy with each other.
"Oh man." Todd smiled. "This is going to be insane. With what it did to you guys, I can't imagine what it's going to do to all of them."
"Oh, it'ssss going to be a reptile orgy, I think." The cobra lady hiss-laughed. "Jusssst promissse you'll think of me when you're looking at all thosssse beautiful lizard women, my eager creator."
"Or the nice sssscaly boyssss." The boa chuckled.
"Now get out of here! Come on!" The cobra giggled, handing Todd the now sealed coffee thermos of his remote created concoction.
Todd opened the door to find Gretta and Fred locked in passion. Humping the ground gently, the male croc had his snout stuck between the giant female's legs as he slurped on her clit. She was splayed to the side, tail thudding against the floor, playing with one breast as he pleased her.
Todd resisted the urge to stay and watch them and gulped as he passed by without any notice. Mission time!

The plan worked flawlessly. Although he drew some strange looks and some surprised (and interested) sniffs from the other reptiles and amphibians on his very naked journey to the janitor's room.
Once at the water valve, Todd found what he was looking for. An old clean out valve on the floor next to the shut off. He turned off the water for a few moments and opened it, pouring all of the thermos of pink bubbling goo in and shutting it. He turned the water back on, and took a deep breath as he knew it was dilluting through the pipes in the building. He turn back to the janitor's desk, opened it, and found a cigarette lighter.
He got a step ladder, stood above it, and found the sprinkler system over his head on the pipes. With a deep breath, Todd lit the lighter and held it above the sprinkler's sensor. As expected, it triggered the fire system. Cool water began to pour overhead and from the puddle coming from under the closed door it looked like the rest of the reptile house was getting soaked.
Todd stepped down from the ladder, engulfed in a torrent of water, and gasped as he realized he felt himself tingling...
