It had been a few months since the incussions happened. Most of the multiverse had been destroyed, and most of the residents of other worlds had perished with them. Though a few of the people of those destroyed worlds; such as Miles Moralis and Spider-Gwen managed to escape to Earth-616. Miles went off on his own for a bit, but Gwen had decided to join the Avengers of this universe. It took a bit getting used too, but she did manage to adjust to her new world, mostly because Wasp was so willing to be a mentor of sorts to her. Though; Gwen did notice Janet acting a bit odd at times.
However, Surter, Mephisto, and Dormamu had all perished in the collision of the universes. However, evil at it's core, can never truly be destroyed. The power of these three remained, and marging together, they found reffuge inside Janet van Dyne. Over the past few months she had found herself having dark, and sometimes erotic dreams. Dreams of universal conquest and sex; especilly with her own protoge; Gwen Stacy. The dreams had become more and more common, and she was now beginning to even think about them during the day when she was awake. Hanging around Avenger Mansion, Janet went into the kitchen and got herself a glass of water.
"Oh, hey Janet." said Gwen as she walked into the kitchen.
"Oh! Hi, Gwen. How are you?" Janet asked taking a sip of water, and trying to resist fantisizing about having sex with the blonde standing infront of her.
"Ugh, Spider-Man's off with Mary Jane again." Gwen said.
Janet noticed the slight annoyed tone in her voice. She herself having talked that way when talking about Hank ignoring her. "Hey, how about a girls night out. Just you and me!"
Gwen smiled "I guess. That does sound fun.".
"Come to my penthouse appartment at 6. I have some stuff I need to do until then."
"Sure." said Gwen.
As Gwen Stacy left the room, Janet held her hand up to her head. Ever since the inccusions happened, she had been feeling weird. Like something was changing within her. Anytime she saw someone attractive she couldn't help herself, she wanted to fuck them on the spot. But that wasn't her, she was no slut. She shrunk down and flew off, thinking maybe a nap might help.
(Janet's Penthouse)
It only took a minute or two to reach her home. Janet put her hand to her head, feeling woozy. Going to the batchroom she leaned over the sink and splashed some water on herself. She moaned as her body began heating up. Janet began to sweat. Breathing heavily over the sink, she found herself having a hard time breathing. Her mind was racing unabe to stay on a single topic for long. A black aura surrounded her body, as the latant powers of the three devils of the universe manifested within Janet, she fell back, passing out and entered her own subconcious, where her dark self took over, and erased the former heroic Janet from the mind.
Janet awoke a few hours later, a bit groggy. Standing up she felt he body was a bit differant. "Uhhh." she moaned, before changing into a chuckle. She oppened her eyes, as they flashed red for a split-second. She ran her hands down her body. The most sexy and sinister woman to ever live now graced the world with her presance. Gone was the kind heroic Janet van Dyne, for now she was the incarnation of evil itself. She looked at the clock. It was 5:50 pm. Gwen would be arriving any second....and Janet would be ready for her. Ready to turn Gwen into her beautful demonic assistant.
(10 minutes later)
Gwen arrived right on time. She knocked and heared Janet telling her to come in. She opened the door and entered the appartment. Dressed in a pair of blue jeans, pink high heels, and a white tee-shirt. She had a black hairband over her long blonde hair. "Janet. You here..." Gwen began to speak as her spider senses went off, as she jumped forward. A black wall of energy sealed off the door, leaving her stuck in the penthouse. "What the hell?" Gwen said to herself. She then turned and saw Janet. Much to her shock Janet was naked, and walking right tword her. "Janet?!?! What the hell is going on?!!?"
"Gwen, great to see you." Janet cooed. "So how you ready for a night of fun?"
"Why are you naked and what is with your door." Gwen angrily shouted.
"Oh, I was just...reworking..my life a bit."
"What do you...." Gwen began to spoke before her senses alerted her to something. Jumping back, she saw chains emerge from a black circle on the ground. She tried to move but was unable to. Looking back, she saw she had run into the dark wall covering the door. Chains emerged from it and pulled her limbs back, to restrain her. "JANET! What is this about?"
"Oh Gwen. So beautiful, yet so smart at the same time." Janet chucked as she walked twoard the bound Gwen. "You, are going to be of great use to me." Janet said.
"What the fuck are you talking abou...." Gwen began to speak, but Janet's eyes began glowing a bright red. As Gwen saw the flashing red lights of Janet's eyes, she began to feel more relaxed, her mind slowed. Forgetting what she was saying, Gwen stmbled her words, as she looked into Janet's bright red eyes, unable to look away. She felt as if she didn't have a care in the world. As if nothing was a problem. All there was, is the red light and Janet's voice. As she continued to look into her eyes, her mind slowed to a crawl, and soon she stopped thinking. The wall of darkness and chains vanished.Gwen landed on her feet, her body hunched over, and her arms drooped to the side, entranced by Janet's hypnotic stare.
"Now, follow me my lovely." Janet said motioning her finger, and waling to her bedroom.
Gwen's legs began moving on their own. Her body hunched forward followed Janet, doing whatever she was told. Gwen followed Janet to the bedroom, and upon orders, did a sexual strp tease for Janet. Gwen eroticly moved her body, dancing as she slowliy stripped down until she was completly naked.
"Now, Gwen. What do you want?"
"I.....want....to......obey......" Gwen said. "I...want....to be...yours....." Gwen said, her body slumped forward.
"You see Gwen, I am now the she-devil. And what I want is to corrupt and fuck the universe, and you will help me with that. Understood." Janet said with a sinister grin.
"Gwen.....wants to....help....mistress.....corrupt.....all life...." Gwen said in a monotone voice.
Janet chuckled as she surrounded her crotch with a dark aura. Using her demonic magic Janet turned her pussy into a large cock and balls. "Now, how about sucking this cock, and maybe I'll allow you to be my slave." Janet said pointing to her large dick.
"As.....you command.....mistress...." Gwen said. Getting down on her knees she began licking Janet's penis. Grouping the balls of the corrupt woman, Gwen pleasured her mistress. Janet let out a moan as Gwen's tounge licked her demonic shaft. Creating a thone made of pure darkness she sat down. Taking the cock into her mouth, Gwen began to suck on the big, long shaft of she-meat, and continued to lube it with her tounge. Taking it out of her mouth, Gwen put her breasts around her mistress's cock and began giving her a tit fuck while licking the tip.
"Excellent slave. Now into the bed, allow me to reward you!" Janet said with a chuckle.
Gwen got up and walked over to the bed. She laid back on the smooth silk sheets, and Janet flew over to her. Gwen's eye's rolled back as she felt the large dick enter her cunt, as Janet began to thrust into her. Grabbing the sheets tightly, Gwen moaned louadly from the pleasure her mistress was providing her. Janet already about to cum from the blowjob Gwen had iven her earlier, grinned.
"Mistress....gah....oh..gah.....please...ohhhh.....make me yours... Make me....a.....demon." said Gwen, her mind blank from the hypnotism and the sheer bliss of Janet's satanic penis fucking her cunt.
"As you wish, slave." Janet said with a chuckle. She launched her demonic seed into Gwen's cunt as she let out a load orgasm. A dark aura surrounded Janet's hands as she used her magic to transform her slave's body. 2 extra sets of arms emerged directly under Gwen't already existing arms. A spiked tail emerged just above her ass and horns poked out the top of her head. Her nails sharpened themselves and grew an inch or two, turning into large black claws. Her skin turned red and black, and her muscles grew. Her abs developed into a strong 6-pack, and her breasts grew into large E-cups. Her legs gained some muscles and her toenails transformed into claws matching those on her 6 hands. As her eyes turned yellow and her teeth sharpened into fangs, her transformation was complete. She was now a demoness, and the loyal second in command of the She-Devil Janet.
Gwen was reveling in post-orgasmic bliss. The sheer ecstacy of the pleasure she had felt left her mind feeling like mush. As she managed to calm down, her mind started to reassemble itself, into a darker, more twisted version of herself.
"How do you feel, my servant of darkness?" Janet said.
Gwen, still breathing heavily from her release began to chuckle. "I feel amazing, mistress." Gwen growled. Her mind altered to loyaly serve Janet in her conquest. She hoped that her mistress would allow her to seek her wrath apon Mary Jane Watson. To turn that bitch into a sinister supervillainess who would serve the great evil of Janet van Dyne and help her corrupt the universe.
The two got up, and chuckled. With her dark magic Janet turned her large dick back into a vagina. A shroud of fire appeared arround Gwen Stacy as she transformed herself back into her human form, to disguise her demon form in case she went out in public. "If you don't mind mistress, there is something I want to take care of."
