Christmas Carol: Rocketgirl yet-to-cum: Serpentina slithers in and impregnates her

"If there are no objectionsssss, I've got ssssssomething I think the ressssst of you will enjoy ssssseeing," Serpentina hissed. She rubbed her belly tenderly and smiled. "Sssssome eggsssss for the former sssssssuperheroine to to lay. Jusssst imagine sssssseeing her writhe and ssssspasssm asssss sshe triesssss to give birth to my beautiesssss..."

Everyone nodded in agreement except Rocketgirl, who began again scrambling to try to get her footing, only for her artificially heavy midsection to pin her back to the ground. "No! No! You can't do this to me!"

Rubber Boy shot another wad of rubber cement at her, catching her throat. It wrapped around her neck and bolted her neck to the floor. Now the heroine folded her arms and legs like a crab to try pushing her body off the floor, but was pinned both by the weight in her belly and the heavy collar around her throat. "No! No!" she panted.

Serpentina began transforming her body once again to its alternate snake-like shape. She knelt and wriggled before Rocketgirl's panicking face and stared into her eyes. "Oh, yessss, my ssssweet," she smiled, then completed her conversion and slithered down Rocketgirl's chest. "Sssssee you on the other ssssside, Rockettitsssss," she hissed before rearing her scaly head back like she was about to attack her prey. She darted into the heroine's pussy with a wet POP sound, Rocketgirl's fingers grasping uselessly at the rest of her wet, scaly body as she squirmed deeper inside.

Rocketgirl clawed at her pussy for a few moments afterwards as though she might still have a chance at prying the villainess from her. She continued to pant as she craned her head to try staring at her pussy, but couldn't see it because the rubber cement collar prevented her from lifting her head high enough off the floor.

Soon Rocketgirl's pelvis twitched and rolled, partly from her own discomfort, partly from the maneuvering of Serpentina within. "Oh, god...ugh!" she moaned neauseously.

Momentarily, she could feel Serpentina stop moving. There was a muted rumbling sound from within Rocketgirl's belly. She felt a growing pressure within her womb, and then the movement started again. But now it traveled in uneven flow within her gut. She pounded the floor in frustration.

"I'm going to break the collar," Ms Kyoto said. "I think we're about to see one heck of a show, and I don't want any obstacles."

Out of Rocketgirl's sight, she retrieved some items from her closet. She walked back and knelt beside Rocketgirl, smiling down at her as she donned a welder's helmet and lit a blowtorch.

Rocketgirl screamed with fright as Ms Kyoto lowered the blowtorch to the heroine's neck. But the professor was careful not to injure the heroine, instead carefully slicing through the rubber cement collar, then scraping its remnants away. She stood back with the rest of the gang.

Now free from her restraint, Rocketgirl only remained pinned to the floor by the considerable weight in her midsection: the rubber cement combined with whatever Serpentina had just deposited in her. She could feel Serpentina slithering throughout her internal organs -- slowly for a time, then quickly, occasionally stopping altogether. If there was a pattern, the nauseous, panicking heroine could not discern it. She barely understood that Serpentina was wreaking havoc within her. Mostly she knew she was bloated and uncomfortable.

Rocketgirl was sweating profusely. She panted, kicked, wailed in agony, and pounded her fists against the floor. She couldn't muster the strength to sit or stand, but she writhed, spasmed, and jerked, much to the villains' amusement. After a particularly long, aggressive slither by Serpentina, Rocketgirl felt bile rise up in her and she vomited on the floor, carefully steering her body to avoid lying in it.

After about ten minutes, Rocketgirl felt Serpentina move up within her chest. Rocketgirl's breaths became shorter and wheezing. Her eyes bulged in a panic when, for nearly two minutes, she felt her throat closing. Then there was a reptilian, pulsing sensation on her tongue and the villains watched her cheeks bulge. Serpentina's head emerged from Rocketgirl's lips, and the rest of her sinewy body slithered out slowly behind. "The worsssst isss over," she hissed when she was halfway out. Rocketgirl's bulging eyes went crosseyed as she stared at the snakelike villainess emerging from between her lips.

Once Serpentina was coiled comfortably between Rocketgirl's breasts, she transformed back to her human form. She gave Rocketgirl a quick peck on the lips and smiled. "Thankssss, preciousssss," she hissed. "Sssssoon the clutch I laid in your womb will ssssspill open, the eggsssss hatching deep inssssside you. Then you'll give birth to hundredsssss of my beautiful sssssnake babiesssss."

Rocketgirl lay panting in an exhausted, sweaty heap on the floor. She slowly shook her head with the last bit of strength she could muster. "No, please no," she whispered.

"It'sssss too late to expresssss your disssspleasssure now, my sssssweet," Serpentina replied. "Ssssstill, the birth processsss ssshouldn't sssssstart for ssssseveral hoursssss yet. Perhapssss one of my colleaguesssss can ssssstimulate you until then?"
