"Oh, Gwen! You startled me. If you're looking for Peter, he just left." Mary Jane said.
"I know, I actually came here to see you." said Gwen as she pulled back her hood and removed her mask.
"Really? I thought you hated me." Mary Jane said.
"That's why I'm here." Gwen said with a twisted grin coming across her face, as she transformed back into her demon form.
Mary Jane took a step back, and began to run for the door. However, with but a snap of Gwen's fingers, she made the door and window vanish to get rid of all of Mary Jane's ways of escaping until her mistress' will had been done.
"G... Gwen? What is going on!?!"
"You have always been such a tease to every man you see! But now, you will not just be a tease, you'll be an evil slut, just as I have become thanks to my mistress!" Gwen said as she let out a sinister chuckle. Opening the bag, the Venom symbiote lunged out, and oozed over to Mary Jane.
Mary Jane took a step back before falling over. “No…. not that!” she screamed as the symbiote started to cover her.
“Yes! And you will soon be She-Venom! A loyal minion of me and the Deviless!” Gwen said, as she began to laugh. The symbiote oozed up Mary Jane’s body, forming a suit, that was almost like a second skin. The black substance covered her from the neck-down. A white spider symbol crossed over her breasts, as talons formed over her hands and feet. Under the symbiote Mary jane’s body began to shift. It Her body became more muscular, and her breasts grew to F-cups. She gained a whole foot in height and 100 pounds of muscles on her arms and legs. Gwen grinned and licked her lips. “Mmm. What a sexy bod you have now!”
“I…I look like a monster!” Mary Jane said as she began to cry.
“No……you look like a beautiful Amazon! A wonderful cross between a bodybuilder and a supermodel. And soon, you will use this body, for constant sex and evil!!! Now, on your knees!”
Mary Jane found the symbiote forcing her body to move, to do as she was told. Before she knew what was going on she was kneeling before the demonic woman in front of her. It was as if the symbiote was bound to Gwen’s will.
“Now, spread your legs!” Gwen demanded, as she used her magic to form a cock around her crotch.
“WHAT?!?!” Mary Jane said as the symbiote forced her body to move to the bed and bend over.
“Time to fill you with darkness and lust itself!” Gwen said as she stroked the massive cock and walked toward Mary Jane.

Thor and Wasp flew through the sky to get to time square where they would meet up with Captain Marvel and She-Hulk to investigate the city for traces of demonic activity. Arriving, they saw the two sitting at a table at a café.
On the left sat a green woman with large muscles. She was wearing a white and purple jumpsuit, and had long green hair. On the left, drinking a coffee, was a woman with short blonde hair, and an outfit that was red, yellow, and dark blue.
“Hey girls.” Janet said, continuing her friendly ruse. Walking up to the two she touched their arms, and just like with Thor, she infused them with her dark power. Just as she had fused Gwen with the sin of Lust itself, she had infused Thor with Pride, She-Hulk with Wrath, and Carol Danvers with Greed, and the more they used their power, the more the sin will take them over, and bend them to her will. Soon, she would have her Seven Sin Sisters ready, to lead her demon army to spread corruption through the universe!
