MJ was walking home when a black monster appeared. It was the Venom Symbiote. Peter had rejected it when he found out it was slowly corrupting him. It's second host, Eddie Brock, was killed during a fight with Spider-Man. It needed a new host and here was one right in front of it.
"Who the hell are you?" MJ asked.
"I am Venom." Venom replied. "And you are mine. Now, ssstrip."
MJ slowly stripped off her shirt and pants. The Venom Symbiote slowly moved up her legs and MJ moaned when it softly touched her pussy. Then it covered her boobs and pinched her nipples. MJ moaned louder before it fully covered her body. MJ loved it. With the Symbiote, she was ten times hotter than she was before.
"I won't corrupt you, I promise. I just want to help you and Peter get clossser." Venom said. "Do you trussst me?"/
MJ nodded.
"Good." Venom replied.
"Hey, MJ. How are you-" Peter stopped when he saw the Symbiote on MJ.
"What the heck? How did you get it on you?" Peter said. "No, no, no this can't be happening. Stop! I don't want to fight you. Block it out! Snap out of it!"
MJ moved towards Peter and before Peter could do anything, she pulled his face toward her and they kissed. Peter couldn't help but moan, feeling their two tongues touch each other. MJ sent a tendril that gripped Peter's cock and he sexily moaned as MJ was thrusting his cock, his eyes fluttering. Then MJ sent a tendril into Peter's ass and he gasped as he was butt-fucked. Then MJ sent a tendril into Peter's mouth and he swallowed the globs of cum Venom produced.
"Are you ready now?" MJ asked.
"Y-Yeah." Peter said.
"Good. Let me show you how much I love you." MJ replied. Soon they were both on the bed, deeply kissing each other, with Peter's hands moving across MJ's body as she moaned. Then Venom sent two tendrils that groped MJ's boobs and sent another tendril that squeezed Peter's balls. Another tendril went into MJ's pussy a third went into Peter's ass and they let out a series of sexy moans.
Both of them were surprised that Venom was fucking them both but it made it all the more sexier. Then Peter was the one ontop of MJ and squeezed and fondled her boobs. MJ moaned with pleasure and her moans turned into screams as Peter put his cock into MJ's pussy. Then MJ went ontop of Peter and rode his cock as they both moaned and MJ's boobs bounced up and down. Both of their moans came at the same time and it was hard to tell who's moans were who's.
"MJ? I think…I'm…gonna…cum!" Peter said in between moans and MJ went down and began sucking on Peter's cock, devouring all of his cum before they both fell ontop of each other.
"Wow. That was fantastic." Peter gasped out.
"Wow indeed." MJ said. "I guess the Symbiote made us both hotter."
"Way hotter." Peter agreed. "I love you, MJ."
"I know." MJ replied sexily. "I love you, too, honey."
Then they both fell ontop of each other and slowly kissed before they fell asleep.
