Todd took off the coveralls, dresses in shorts and a t-shirt, and lied under the covers of his bed. He cuddled Gretta’s egg close to his cheek, nuzzling the smooth surface. Inside, he knew the embryonic reptile was developing fast. He occasionally checked her stats on the remote and gulped as the egg began to grow longer and wider. After a half hour or more, he heard a tiny muffled peep and sat up in excitement.
The egg developed a crack at first, then began to split, and eventually a fully developed baby crocodile emerged nose first and peeled her way out. Todd peeled off bits of egg and smiled as the baby anthro crocodile stared at him, blinking in shock as she remembered his face. She was a little baby, just over eight inches tall, but stubby and humanoid.
Carefully, Todd picked up her slimy body and carried her over to the kitchen sink. Todd ran a warm bath as he cradled the croc in his arms and watched in amazement as she oh so slowly grew in his loving embrace.
By the time the sink was filled, Gretta was 14 inches, a little stockier, and about six months old. Todd bathed her, cleansed her with a soft sponge, and giggled as she playfully splashed in the water with her hands, feet, and tail.
When she was done, he removed a 20” tall 1 year old from the sink, finding her more defined and heavier, and dried her off. The baby croc giggled and growled playfully, snapping at the towel.
Todd set her down in the carpet of his room and began to play with her as she started to crawl. They played peek a boo, chased each other, all the while gleefully giggling, as soon Gretta began to pull herself up onto things.
Now 26” tall, Todd grabbed her tiny hands and held her up as she began to shakily walk. Growing and developing all the while, she had soon mastered running. Todd found himself chasing a wild three year old crocodile girl as she explored the room, nosed into things, and looked for mischief.
“Hey, Towd!” Gretta began to talk at three and a half, her tail swishing, 32” body starting starting to show early signs of lean muscle growth.
“What, you little monster!” Todd laughed, sweating from keeping up with the reptile, played out.
The crocodile laughed innocently and shook her head, pointing a finger. “No, you’re a monster! A monster butt head face!”
“That’s it!” Todd said, grabbing the surprisingly dense and weighty four year old as she reached 38” and hefting her up into his arms. “You come sit on the couch, missy! Time out!”
“Noooo!” The croc giggled, kicking her webbed feet and flailing her tail with slaps against his arms. Yet she happily giggled as Todd threw her down onto the springy old couch and giggled as she plopped down next to him.
Todd turned on the TV and threw on some cartoons. The rabbit was doing something to the hunter. Gretta’s eyes widened in wonder and then she began chuckling and pointing. As she grew into a 49” five year old, Todd noticed in amazement she was already showing size and definition to her body. Though still young, she had clear muscle beneath her leathery hide, defined and starting to grow tighter.
Todd stared as the young reptile cuddled into him as her biceps swelled, her little amount of baby fat melted, and she grew leaner and more muscular. Indeed, she already had a taut belly and a firm broadened chest. A 53” tall six year old soon became an athletic 56” tall seven year old.
At seven, the much bigger crocodile turned away from the TV as she started to remember. She let go of Todd, sitting up, and seemed to realize her process. She studied her new increasing muscles, watched them subtly bulge and fill, and rubbed her body in her scaly hands with a delicious young moan.
Todd stared open mouthed and grinned as seven and a half Gretta giggled girlishly and clapped his mouth shot in her hand. “Don’t get any ideas, monkey, I’m still just a little girl.”
As she rose to 59” and eight years old, Todd stared in amazement. She was buff, with clear rounded biceps, tight hips, and a powerful tight torso. Even her long sinewy tail was heavier and defined with thick cords of muscularity down its length. Gretta stared at herself as the minutes ticked by and gasped.
“I... I remember.” She said suddenly, eyes widening. “I remember everything. I was shrunk. I... I was an egg. I felt everything. I could feel myself growing in my egg.”
“Really?” Todd leaned in excitedly, putting his arm around a big 62” nine year old. Her hips were rounder, her legs longer, shorter snout starting to lengthen. Her shape was just hinting at a female form, yet Todd knew she was entering puberty now and starting to mature.
Gretta noticed how big she was getting and seemed to duck shyly under Todd’s embrace. “Yeah. Look at me now.” She put a scaly finger on the human’s lips and pushed his face away gently. “Not yet.” She smiled. “I remember. I know what you want. I’m not old enough yet, Todd.”
“S-Sorry.” He gulped, offering a sheepish giggle. He checked the clock and blinked. It had been two hours since Gretta had hatched, she was now 65”, almost the size of a man, and only ten years old. Her muscles were amazing, thick, bulging, fully athletic, yet somehow lean and feminine.
A sudden flood of hormones and growth made Gretta gasp out loud and she grabbed her chest in both hands. At eleven, and 67”, she removed her hands and both she and Todd stared at two tiny scaly dark green nipples that had formed and risen on her hard pecs.
“Ooh.” She gasped. “Y-You really changed me, huh?”
“Y-Yeah...” Todd blushed in embarrassment. “Do you like... I mean...”
The human was startled as the slow growing crocodile gently but assertively cupped his chin in her powerful webbed hand and touched the tip of her long jaws to his lips. She grew to Todd’s height of six feet tall, and while still just starting to get her breasts and curves, she was a magnificent and shapely twelve year old. She kissed the human, flicking her tapering tongue onto his and sensually lapping at the roof of his mouth.
Todd reached out to put his arms around her for a hot interspecies make out session, but was suddenly stopped by the buff young crocodile grabbing his wrists. Gretta pulled away teasingly and Todd opened his eyes to find Gretta sitting next to him with a devious smile. She was now twelve, a bodybuilder in muscle size, and her little nipples were starting to rise over budding reptilian breasts.
“Control yourself, monkey man. I’m still not old enough for you.” She said playfully, voice a little huskier, but cracking oddly in depth.
Todd tried to struggle free, grinning madly, as growing 6’2” Gretta rose from the couch, pinning him down as she leaned in, and drew away to leave him sitting and sweating with arousal.
Gretta noted the firm bulge in his shorts and nodded seductively, caressing herself for him, tracing the contours of her huge muscles. She flexed her big biceps, swelling them, and cupped her growing breasts. They were really starting to stand out. Her pecs had softened somewhat and her boobs were now immature but still shapely B cups. They seemed to be speeding up their development to the point Gretta could feel their pert tissue swelling under her hands.
She was now thirteen, and a staggering six and a half feet tall. She turned around for Todd to admire her firm rump and slowly swelling hips and ass. Everything on the crocodile’s body was huge and defined, every inch of her laced with tight and powerful trunks of reptilian muscle. She was growing scarier and fiercer, scales hardening in, the ridge of spines down her neck, back, and tail turning to hard razors.
She turned around at fourteen and nearly seven feet tall, her womanly curves starting to show with a vengeance, and rubbed her hands all over herself as she slipped a hand down between her legs. She shut her yellow eyes and moaned seductively, masturbating in front of Todd and knowing she was driving him insane. Indeed, she heard him rubbing his dick through his shorts.
She hit fifteen, seven feet tall, and removed her fingers from a tight red pussy to lick her own juices from her claw tips. Her breasts were big, her developing curves were inflating by the second. Her muscle grew still harder, and her height continued to climb.
She opened her eyes at a buff and busty sixteen, impossibly huge and powerful at 7’8”... seductive dark lashes forming over her eyelids, and stared at Todd with the most incredible fuck me eyes he had ever seen. They were intense, predatory. Gretta growled deeply and smirked her crocodile smile.
“Come on, Todd.” She held out a massive reptilian hand and he took it excitedly. She grabbed the human and picked him up effortlessly into her arms.
“We’re going to the bed.” Gretta grinned. “I’m old enough now.”
“Oh thank God,” Todd laughed, the bulge in his shorts poking out obscenely. “You dastardly tease!”
The crocodile and human jointly laughed as Gretta set him down on the edge of the bed and laid down next to him, making the old springs creak. She put her thick arms behind her powerful neck and leaned back with a huge grin. “Do what you will!” She laughed, still growing even more massive by the minute.
