Todd took a moment to relish Gretta's crocodillian body and they exchanged a smirk and a laugh with each other as the giant reptile woman sat down on the couch and stretched her muscular arms over the back. Her pussy was still throbbing and she sat with lust on her long face.
"Damn, Todd..." Gretta growled seductively. "Keep that up and I may have to change my mind about monkey people like you."
This elicited a gentle bemused laugh from the snake and she stared up at her human changer expectantly. "I don't know. For how long I watched your kind through glassss, I could never have imagined with my animal mind that you could be ssssoooo delightful."
"Well, I guess I'll have to live up to that."
"Mmm." The snake extended her forked tongue several times. "You ssssmell of Gretta and ssssexxxx. It isssss wonderful. I hope to add mysssself to your ssssscentsssss."
"Well, let's get you to a more respectable size, then." Todd grinned, reaching for the remote from his discarded pants.
"Waittt..." The cobra smiled sweetly. "Before you take me farther into my new form, I wissssh to do sssssomething to you."
"Oh?" Todd blinked. He looked down and gasped as the little snake woman, somewhat human like but still having far to go, gently put her hands over his limp cock and began to stroke it gently. Todd staggered back as her tiny glassy palms rubbed over his tip and her dainty fingers cupped his shaft. Predictably, he began to grow aroused again. His cock began to rise, to the tiny snake girl's keen delight.
"Ah!" The cobra grinned up sweetly, adorably. "Good!"
Todd stared in wonder as the small reptile leaned her neck down and began licking gently. The sensation was otherworldly, the forks of her tongue hitting places and spots with precision and care. Flicks of pleasure as she flicked her tongue, while her tiny hands continued to work and massage his shaft to full erection. As Todd rose to full size and gasped, the cobra lady giggled and gripped him, pulling his tip down to her mouth.
"You may grow me now." She said with casual approval.
Gretta, in the back, watched the display with renewed arousal. Her suppressed and ignored sexuality had grown with her immense new body, and the crocodillian let her fingers slip between her already spread legs to toy with herself.
Thus, Todd hit the button and activated the snake woman's transformation in full as her tiny muzzle closed on the giant tip of his member and she began to blow him off. She could barely mouth his slit, but that soon began to change as the snake woman moaned and began to grow in size and shape.
The little cobra girl was lean and long. Still strangely proportioned in body and more snake than woman. She began to slowly shift, gulping Todd's cock eagerly and licking it with her tongue as her growing hands jerked him excitedly.
The human leaned against the desk and let it all happen, a wall of pleasure hitting him from the snake's tiny attentions. She was helplessly turned on as she now changed constantly and slowly, the transformation burning through her body making her squirm and clench her thighs while her hands were busy.
The crocodile began to masturbate faster and faster, excited as their snake friend began to grow much more substantial. Watching the process and knowing how good it felt was a sexual thrill for the big croc. She knew the little cobra girl must be feeling everything she felt.
Todd felt the snake's mouth take more of him deeper and opened his eyes to see she was now taller than his hips and about stomach high. She was starting to even out in porportion. Her arms and legs were growing, her body shape was smoothing and defining. Her overly long snake tail was shrinking back into her ass, whille her head and neck were compressing downward.
The little serpent girl was enjoying herself so much and lost in so much pleasure she didn't noticed as Todd reached down and parted her mouth from him with a wet slurp. The cobra opened her eyes and moaned as Todd picked her up like a doll, sitting on the desk and placing her in his lap. His finger ventured over her chest and stomach, he rubbed her scales under his finger and travelled downward. She gasped as his finger slipped between her legs and trembled, reaching up and grabbing the human's neck as he penetrated her.
Gretta gasped and almost fell off the couch. She crawled to all fours and leaned over the desk to kiss Todd. He moaned and gasped as the giant crocodillian held the back of his head firmly and snuck her tongue into his mouth. It was the most erotic thing in the world as the snake grew, Todd's finger pleasuring her within, and the human and crocodile made out. Eventually, Todd broke away to see the cobra lady was now about chest high and entirely big enough to fuck. With a giggle, he pushed Gretta's giant jaws back, the crocodile snarling in mock annoyance, and grabbed the cobra by the thighs, picking her up.
The snake grinned madly. "Yesssss! Yessssss!"
Todd didn't need encouraging. He slipped his dick between the snake's legs and sheathed himself inside of her. If Gretta had felt amazing, the miniscule and still growing pussy of the snake felt even better. The serpent hissed and screeched as her human lover fucked her gently on the desk while she grew.
Gretta fell back and began to whimper as she squeezed her clit and masturbated. Wet slurps of the crocodile's fingers filling herself began to sound.
Meanwhile, the growing snake was looking decidedly more humanoid. Lean yet powerful, she had fallen into her developed shape and perfectly resembled a tight hourglass cinched woman, save for the scales and snaking tail curling down Todd's leg. The reptile reached down and began to circle her clit as she and her human friend blissfully fucked, Todd taking her deeper and deeper with ease as she grew to man size. Eventually, they raised from the desk and Todd bent the reptile down on the ground, eagerly falling on her and taking her from behind rather forcefully. The reptile's new ass smacked as Todd hit her. She loved it! The serpentine woman hissed and cried out as she closed her eyes and let her human master fuck her hard, even as she kept growing past five feet tall and onto six, growing shaplier, more muscular, but still lean and tight.
As she began to finish her transformation into a tall and lithe cobra woman, Todd unloaded with a cry, filling the snake's pussy with a second creamy load and falling back panting. The serpent turned gasping and realized her new scale, just as Gretta grabbed her shapely little ass cheeks in her palms and leaned in to begin tonging the snake's pussy.
"G-Gretta!!" The cobra gasped, but didn't object as the big crocodile now took her turn with the snake, lapping at her clit and drinking down the mess with a giant pointed tongue protruding from her half open jaws. Gretta moaned and grunted as she continued to pleasure herself and carefully bit down on the snake's groin and most of her stomach, holding her in pointed conical teeth but not breaking the scales as she licked the snake and hand fucked herself.
Todd watched the display with amazement as finally the snake girl pulled her head back, arched, and her tail curled into a spiral. She kicked her leg and screamed out loud as she orgasmed, her lean tiny frame shaking violently as Gretta brought her to climax and beyond.
Exhausted, the serpent collapsed in a heap as Gretta released her from her jaws, gasping desperately with the crocodile continued to masturbate.
Todd crawled over the heap of the panting snake and grinned as Gretta put her mouth to his, kissing again as she suddenly rumbled and threw her head back, shaking her ass and legs as her second orgasm hit full force, making her whimper and writhe.
At last, all three exhausted creatures sat up and relaxing, all with incredibly pleasured expressions.
"Well." The cobra panted, smiling wide. "Ssssshall we go make sssssome otherssss to play with?"
