Todd picked up the remote with his free arm that wasn't being dry humped by a snake and pressed the button again. The cobra paused mid-grind and hissed sharply, overwhelmed with sensation, as the four bumps pushed out further. She crunched slightly as bone within began to reform and crackled. She coiled tighter, holding Todd's arm in a snakey death grip, and fell flat, barely hanging on and panting as it finished. She turned her head and blinked, seeing the bulges along her sides had grown out further. They were still useless and tiny, but to her amazement she could move them independantly, wagging the little nubs. Along her midsection she had bulged out slightly, thicker. This was normal for a snake, but the strange bottle shape of her seemed to be the start of a torso. She had inflated a little to accomodate growing organs and bones.
"Todd..." She panted desperately. "I... I... can you put me down on the desssssk?"
"S-Sure, little miss." Todd whispered, absolutely fascinated and aroused himself beyond normal measure. He carefully carried the snake to the desk and set her down. She rolled to her back, panting in heat, and for the first time Todd saw the obvious pocket of her hidden sex organs, placed around her "legs" on her belly. It was pronounced, swollen inside. Carefully, he reached forward and saw her nod excitedly in delight. He touched the warm bulge and was treated to the snake tensing and hissing, a little bit of clear lube leaking out from the pressure of his touch.
"Again." She persisted, falling lazily limp on the top of the desk while Todd sat in the chair.
Todd pressed the button on the remote. The cobra jumped and squeeled. The limbs grew a little longer, more pronounced at the growing shoulder and hip joints. Her body crackled, she widened below "the neck" as her collar bones grew in. She let out another writhe and threw her head back, clenching her eyes. "Yessssss! YESSSS!" She hissed sharply. "More! More! MORE!"
The display was so erotic that Todd found himself uncontrollably masturbating through his pants. Another zap from the remote. The snake began to convulse and he noticed her feminine slit pulsating rapidly. Her limbs grew. The bulges in the side of her body began to resemble limbs cut off at the elbow and lower thigh. She was developing a torso shape and her tail was slimming rapidly below her groin area.
"Ah!!" She cried. "Don't stop! Pleassssse! I'm going to have an orgassssm!"
Todd complied, pressing the button and watching as the reptile began to buck her groin into the air. She was really starting to define now. Her arms and legs were developed up to the knee and began to press even longer. Her body was still mostly serpentine save for a barreled and inflated bulge that was starting to look like a very immature approximation of a human torso. He zapped her again and watched with amazement as she bucked harder, humping the air and hissing strongly, tears welling up in her eyes as she approached the very first orgasm of her life. Her new limbs flailed and kicked out as she grew up to the wirst now, forearms and shins nearly complete and shaped, not nearly large enough to support her yet but growing in nicely.
Todd refrained from pressing the button, trying to keep her just on the edge of release, and heard the reptile whimper, her head falling to Todd's side as she stared at him with shock and delight.
"Couldn't... I couldn't have dreamed anything would ever feel ssssoooo goooood." She rasped, letting out a hysterical laugh and falling back panting. She took a moment to take stock of herself and raised her neck to look down at her strange pseudo-torso and grown limbs. She flexed her disproportionate legs and arms and stared in amazement.
"Ohhh..." She hissed, "Pleasssse don't stop. I have sssso far to go."
"I had no intention." Todd whispered, leaning in closer as he began stroking the cobra's exposed belly and being sure to massage the hot slit above her tail section. The snake moaned and relaxed, tension building inside of her, as Todd hit the button again...
