Peter tried to comfort Gwen, unknowingly falling into her trap. Unbeknownst to him, she cast her dark magic, given to her by Janet to give herself some pheromone abilities.
"Gwen, listen to me!" Peter said, as her pulled down Gwen's hood and removed her mask. "It's not your fault. We will find a way to get Mary Jane back to herself."
Gwen pretended to sniffle at Peter's words. Trying to keep up her facade until the pheromones made Peter want to fuck her. "You're right. Let's try and find her!" Gwen said putting her mask back on. "Maybe we can find a way to save her."
"Gwen. Let's wait til tomorrow. Let's just hang out for tonight. In the morning we'll try and find her."
"Yeah. Maybe we'll have better luck when the sun comes up. How about I put on a movie, and we'll go as soon as the sun comes up." Gwen said.
"Sounds good." said Peter

Janet laughed as she rammed her dick into Thor's sweet red lips. "Mmm, that's it babe! You sure know how to suck cock, slut!"
Thor tried to speak, but the cock being jammed in her mouth, prevented her from speaking.
"Hmmm. You have such a nice juicy ass!" Mary Jane said leaning over Thor to whisper in her ear, continuing to thrust into the Asgardian's butt with her symbiote dick. "Nice and tight too!"
Thor's mind started to feel numb as the two evil woman continued to use her body. Janet's curse having sapped her will, and made her unable to fight back against this made a tear fall down Thor's face, as she was continuously violated by Mary Jane and Janet.
"I can feel it, Thor." Janet cooed, as she moaned. "Your mind is twisting, turning into a sinister evil bitch. With each such of my cock, and each thrust MJ does into you, the more and more you will want to fuck and corrupt! Just give in dear, and follow me in our sexual corruption!"
Thor moaned as a second symbiote cock entered her cunt, as she was lifted into the air. Her mind being tainted, her power growing as her inner light was extinguished. Finally with one last though, Thor felt Janet's satanic cum flow down her thought. Filling her with her evil, and power. Mary Jane pulled out her symbiote dicks. Having the symbiote again form her suit, MJ moaned as two tendrils jammed themselves into her ass and cunt. Janet pulled her cock out of Thor's mouth and using her devilish magic turned it back into a vagina, and the muscular woman was thrown to the ground.
"So, Thor, how about it?" Janet said bending down and whispering into her ear. "Serve me, and my goals, and I will make sure you will always feel great pleasure! Accept my power, and I will make you a commander in my legions of demons!"
Thor breathed heavily, her mind a mess, but soon it managed to start to reassemble itself, but as a more twisted, and sinister version of herself. One who desired to fuck, one who desired to corrupt, one who desired to rule. Janet would lead her to that, and she would follow her into a dark future. Thor held out her hand, and Mjolnir came flying, and was caught by the goddess. The corruption of Mjolnir, now making it wieldable by the now evil Thor. Standing up, her strong-looking, yet busty naked body on full display. Thor's hair was in a mess, partially covering her face. Soon Janet could hear a sound. A sinister chuckle from the goddess of thunder as a sinister grin crossed her lips.
"Yes, mistress! I swear thy allegiance to thou sinister goals!" she said rubbing Mjolnir against her cunt.
"Mmm. Perfect my dear." Janet said as she walked over to her new servant. She ran her hands down the body of the female Thor. Her muscles, her perfect skin, those large breasts. She had just corrupted a true beauty to her side.
"Mary Jane!"
"Yesssss missssstressss?" She-Venom said as the symbiote covered her face forming her mask.
"Seek out Peter Parker's other ex-lovers. Betty Brant, Liz Allen, and what ever regular girls he ever dated!" Janet said as she cast a spell. "Your symbiote will be able to impegnate them with new symbiotes! Ones that will warp their minds, and twist their morals until they are brought to our side!"
"Ssssoundsss delightlfuly sssssinisssster Misssstressss Janet! We would love to!" Mary Jane said with a evil, almost psychotic laugh. "We'll create an army of evil sssssymbiote ssssslutssss for you and misssstressssss Gwen!" The symbiote covering her fingers extended out grabbing a ledge and she swung off out of Janet's penthouse, ready to corrupt more innocent girls
"Now Thor, who should we corrupt next. The universe is filled with heroes and heroines, all ripe for the picking!"

Peter and Gwen sat on the couch as they watch a movie. Both of them still wearing their costumes aside from their masks. Peter was having a hard time avoiding eyeing Gwen as they watched the movie. For some reason she seemed to be even more beautiful than before. She snuggled up to his shoulder, until Peter pushed her away.
"Gwen, I'm married to MJ, remember." Peter said.
"Oh, come on. I don't think MJ would mind. After all, it would just be between friends." Gwen said batting her eyes.
"Well...." Peter said beginning to think, when Gwen suddenly pulled his pants down and started sucking his cock. Letting out a moan he didn't try and fight back, as Gwen sucked his dick. Unknown to him, his very will and mind were being sucked out as well.....
