Dr. Sivanan does not stop at just tying up poor Mary! He turns him into his evil mate.
By Dr. Bone: Who Sez: This is a parody, done all in fun and not the real thing. For adults only!!! Mary struggled manacled to the examination table in the hidden laboratory of Dr. Sivana. If only she could say her magic word and become the other Mary, Mary Marvel, she could easily snap the restraints that held her tight. But the gag in her mouth prevented her from talking. Something was different about Sivana tonight. And did he cop a feel off of her as she was tied up?
The ugly, evil bald scientist laughed his maniacal, "Hee! Hee! Hee!" as he paced his lab. "I have something special in store for you tonight Mary." he said, he then grabbed her tits and there was no doubt about it now as he squeezed them. "So small and tender, a bit too small but I will take care of that later. Hee! Hee!"
As she struggled he undid the buttons on her blouse, then he took out a pair of snips and with three quick cuts he took off her bra. She felt his hot breath on her breasts and vowed he would pay as he kissed her nipples and began to suck on them. And yet part of Mary was turned on, she did not know if it was the bondage from being tied up or if it was how ugly he was.
She could see the huge bulge in his black pants as he leaned over her. His hand reached up her skirt and rubbed her pussy through her panties. Then his finger slipped into her pussy, after several thrusts he pulled them out and licked her juice off of them. Then he yanked her panties around her ankles and picking back up the snips and cut them off. He held them to his nose and sniffed them tenderly before throwing them into a corner of the room.
Then every nightmare she had ever had came true as before her eyes he undid his zipper and pulled out his cock. In disbelief she stared, it was pink and huge with a giant round head matching the head of its owner. And it was already as stiff as a board. He laughed his maniacal laugh again. Where was Billy, her brother also known as Captain Marvel, he would save her. But the walls did not come crashing in. Sivana pressed a button and the stirrups her legs were chained to spread her them wide. She struggled to no avail as he slowly lined up his cock and pushed it into her.
His size was so big and he was so hard she did not think she could take it, but he kept a steady pressure on her and the head popped in to her unwilling vagina. Sivana started to thrust as his hands played with her breasts. Mary planned to take revenge on the little gnome as soon as she could get out of this trap she had fallen into.
He thrust faster and harder and until he came inside of her. She could feel the hot load shoot into her violated pussy. He laughed some more and came around the other side of the table wiping his cock across her face and forehead.
"Pop! What the hell is going on it here?" said Thaddeus Bodog, who preferred not to be called Sivana Jr."
He was followed by his equally ugly sister Georgia who yelled "You have gone too far pops! Really!"
Mary saw some hope, maybe they were not so bad after all! Then her hopes were dashed as they began to strip. "Yeah you were supposed to wait for us." Georgia complained.
"But first we have got to take the gag off her, how else is she going to lick my pussy." said the ugly girl as she and her brother took off their wigs to reveal they were as bald as their father.
"Then we are going to shave her head." Added Thaddeus as he undid Mary's ball gag.
"Shazam!" Mary screamed waiting for the lightning that would change her into Mary Marvel, but nothing happened. She had had nightmares of being in a plane about to crash and not being able to change, now they were coming true. "Shazam! Shazam! Shazam!" she said starting to cry.
The family danced around her naked mocking her by chanting her magic word and laughing.
"This room is soundproofed both in the physical and metaphysical. That old wizard cannot hear you!" laughed Sivana.
"What are you doing?" she asked as he took out a needle and injected her with a pale green fluid.
"You will see." he giggled.
As Thaddeus shaved her pussy Georgia shaved her head with her father's sonic razor. The hair disappeared with each pass leaving her head perfectly smooth.
When she was done the ugly woman rubbed her pussy against the top of Mary's head coating it in her juice. Mary began to feel her own pussy tingle. Her nipples started to harden. "What was in that shot?" she wondered as Georgia lowered herself onto Mary's face and told her to lick it.
"Come on you goody goody bitch lick it!" Georgia said squeezing Mary's throbbing nipples. She rubbed her cunt across Mary's face until Mary finally stuck out her tongue. Georgia made Mary lick her pussy harder and faster by brutally squeezing and twisting her nipples when she did not comply.
Thaddeus plunged his cock into Mary next, his cock was even bigger than that of his father.
Sivana climbed on top of her and fucked her tits as his daughter held them together for him. Then he lowered the back of the table so her head leaned back and over the edge and rubbed his cock against her closed lips while his daughter licked Mary's tits and tongued her navel.
"Open up! Come on!" Mary did not want to but then she noticed her tits had become larger. "Yes I injected you with something that is going to make those little boobs of yours not fit into any of those cute lacy white bras you own. And it is making you hornier by the moment also. Can't you feel it? If you want the cure, which only my own twisted evil mind possess you will open that mouth of yours. Come on! Yes! Hee Hee!" he said as he plunged his cock into Mary's mouth.
"Deeper! Deeper!" he ordered. To punish her he pinched her nose shut and plunged it down her throat making her gag and choke. "Now deeper!" He ordered as his balls slapped her forehead.
She started to moan from the fucking she was getting from Thaddeus. She felt his load shoot into her. "That's it take it!" said Sivana as she tasted his hot bitter cum in her mouth. He clamped his hand around her mouth and made her swallow every drop, again smearing it all over her face and bald scalp.
Georgia then got on her knees and had no problem licking her father's and brother's seed out of Mary's used pussy. Under the skilled lesbian's tongue Mary came like she had not came before. Sivana unshackled Mary and told her she was free to go but she did not, out of shame, and out of lust.
As Georgia worked Mary she jerked off her brother and father. Mary got on top of Sivana's cock as Georgia slowly guided her brother's oiled penis into Mary's ass. Tears ran down her eyes but she took it and all the pleasures that double penetration brought. She knew she could never go back to the Marvel Family again after being used in such a manner, she knew some of it was the serum, but some it she had fantasized about playing with herself under the blanket in her mother's mansion. She could not go back, but where to go next? As fate would have it that decision was taken out of her hands.
After both men had finished with her she was told to get up. As she did she felt their seed run out of her ass and pussy and down her legs.
Sivana flipped a switch on the wall and then he turned to her, "You can say your magic word now. Go ahead."
Suspecting a trap Mary hesitated for a moment, then a plan came to her mind, she could still change, capture the villains, and say they lied about what she had done. Yes she could still be the hero.
"Shazam!" she screamed, but the word echoed through the chamber, and distorted until in her own voice it became "Sivana!" then the word flew skyward, and a bolt of lightning came down and struck Mary, she changed, but not in the usual way.
She felt her self becoming more intelligent and evil. "What have you done to me?" she cried as her face became uglier, more similar to the Sivana's.
"No, it is what I have done for you. I have made you beautiful and smart."
Under a daze they dressed Mary in a white lab coat and black pants with boots. Though she did not need them they gave her a thick pair of glasses, and why not? She was now a Sivana.
The evil scientist got on his knees and asked her to marry him and be truly Mary Sivana. She punched him in the jaw and told him yes.
The wedding party was a riotous affair with the full Monster Society of Evil attending.
After a honeymoon in some of the most evil and vile places on and off earth the new Mrs. Sivana took charge of the household.
"Don't cry out your father cannot hear you, I drugged his milk. You and I have to get something straight on who the boss of this house is." said Mary to the tied up Georgia, "As your brother found out." Mary hit a remote control and an image appeared on the wall of Thaddeus tied up. A robot fucked him in the rear with a huge dildo as it reached around to jerk him off, on his ass was a brand mark, read "MS".
Georgia yelped as the branding iron burned into her flesh. As she sobbed in pain Mary laughed "Hee! Hee!" as she strapped on a horse sized studded dildo to teach her step-daughter a lesson
As it slowly stretched Georgia's pussy to its limits Georgia smiled, she was proud, her stepmother was truly the world's most evil woman.
