Peter opened the door as the symbiote formed into a black T-shirt and shorts.

MJ came in with a seductive smile.
"Hey Tiger, I just got off work and I'm wanting a little something." She whispered as she dropped off all her bags. Peter growled slightly as he picked up MJ and they went into his bedroom. He put MJ on the bed as the symbiote formed over Peter again this time with his cock hanging out. MJ undressed herself and she pulled down her panties revealing her flaps. Peter pounced on the waiting MJ as he teased MJ occassionally let his pole touch her vagina. Finally, he drove it in as she moaned. He slid out as the symbiote encased his cock and tentacles sprouted out. He drove it in and they both moaned as the tentacles pushed up against her inner walls, sucking it clean and caressing it.
More tentacles sprouted out as they plunged into her ass causing her to gasp.
"Wow Peter, you're already making me..." she said trying to hold it in. THe symbiote reached her clitoris and encased it in it's slime causing her to scream.
"CUM!" She yelled out as her pussy juices started flowing. Peter began reaching climax too and his seed began pumping out of his dick and into her womb.
Unknown to him, the symbiote was ready to spawn another symbiote. In the symbiote's memories it saw MJ as Peter's mate and wanted to gift it with it. As semen flowed in to MJ, so did some red slime. Peter didn't notice as larger and larger amounts flowed into her while tendrils sucked up her pussy juices.
He finally slid out as they panted. However MJ, contniued to feel pleasure. Peter was confused as to why that would happen as all the tentacles retracted back to his suit.
His eyes widened when he saw red and black slime flowing out aggressively out of MJ's flaps causing her to moan again. The new symbiote covered the hole while forming a dick to penetrate into her. SHe moaned more and more oblivious to the bonding as it crawled down her legs turning her feet into claws.
"Oh! PETER!" She yelled as Peter gazed at the bonding scene. The symbiote continued crawling and expanding as it slapped down onto her breasts causing her to gasp. Some of the slime  wrapped around her back before a lone tendril flowed down to the top of her crack and stopping. The symbiote crawled up and stopped just below her neck and rose, ready to pounce. All at once, the symbiote penetrated her vagina while the tendril plunged into her crack causing her to open her mouth giving the symbiote a opening. It plunged in as she finally realized what was happening however the penetration was too distracting for her to take action.
The symbiote flowed over her face turning creating teardrop shaped eyes as her new mouth formed. The symbiote turned her red hair into small symbiote tendrils as her new mouth opened up showing large amounts of sharp teeth and a long tongue. The bonding/sex finally stopped although the symbiote covered her clitoris, keeping her at a high. She leapt up and leaned into the shocked Peter.
MJ's costume looked similar to like a female version of Carnage and Peter realized that in this timeline, the symbiote had yet to spawn Carnage so when it did, it bonded to the closest person which was MJ. Peter was at least thankful that he didn't have to deal with a crazed maniac like Kassady in this universe. He looked up and down at the differences. MJ's breasts had gotten bigger to about a D-Cup and the symbiote hugged her tightly showing all her curves and leaving nothing to the imagination. Her hands had small tipped claws and her symbiote hair flipped and twirled in the air madly.
"Hello Lover! How do we look?" She said seductively as Peter's member throbbed from the scene and the excitement of what to do next. However, Peter's morals still stand as he was conflicted as to whether to give in or do something.
"Come on! Don't keep us waiting." She whispered as green ooze leaked out of her vagina.
