The next stage of evolution

Peter laid on the ground, stroking his massive belly, his legs spread out wide. The ladies stared at his massive cock but they were so delightfully tired from the hunt that for once there was no urge to mount him. Though that didn't stop Cindy from lightly jerking Peter off while Gwen nuzzled him.

As for Mary Jane, the one that had truly started all of this, she looked at the other three and smiled, the mask she wore peeling away to reveal her own lust-filled gaze. They were lying on one of the floors of Kingpin's tower, bellies heavy after they had eaten the Wrecking Crew, and thanks to their bond she knew each and every one of her mates was thinking the same thing: why had they waited so long to do that?

"Venom?" she said softly, loud enough for the others to hear.

'Yes?'

"Now."

Venom knew at once what MJ meant and all four of them cried out as they at once both orgasmed... and bonded even further with the symbiote.

Their bodies swelled out rapidly, truly becoming gigantic and size. And it wasn't just that they gained weight... they become taller. Bigger. Rising to nearly 20 feet tall and just as wide so that they were truly blobby spheres with arms, legs, feet, and delightful pleasure zones. The venom costumes that coated their skin rippled and Mary Jane moaned as the black ooze sank into her stick, causing it to darken like she'd been tanning all summer. There was no need to hide who they were anymore... they were venom and venom was them so why bother with suits? the patches of white became like beauty marks or tattoos on their skin, each one of them spotting a white spider along with splashes of white around their arms. Mary Jane lifted up her fingers and saw that while they looked rather human the ends were now pointed claws, the same with her huge feet. Her face widened as she gained yet another chin and she smiled, feeling her lips pulling back further and further as her mouth became larger. She glanced at Cindy who, despite having her human features, opened her massive mouth and wiggled her elongated tongue her. Gwen squeezed her nipples as they jutted out from her wreckball-like breasts and Mary Jane licked her lips as she stared at her puffy pussy and huge throbbing clit.

Moments ago there had been no need for Mary Jane to mount Peter. But now staring at his cock that was as big and wide as he had been before their bonding she crouched down and leapt into the air, slamming down on him and causing the floor to cave in. They fell only for a moment before all four fired out webbing, stopping and allowing Mary Jane and Peter to begin fucking in earnest. She rode him, using newly enhanced muscles to squeeze and milk his massive cock while Gwen and Cindy licked at his massive hairy balls.

All thoughts of her life as a model, as a potential hero, as a girlfriend... as a human... faded away. She could feel the same thing happening to Peter, Gwen, and Cindy. In fact she reached through their link and grabbed any passing thoughts about what it meant to be human and gobbled them up like she would any snack. They weren't human... they were so much better! Why bother with such concerns anymore? She wanted them to only think of the four of them. of their lives... their pleasure.

"Only we matter," MJ told them as she felt Peter tense before she too screamed as venom helped the two cum at the same time...

...and in that instant Mary Jane felt the symbiote open her womb and let as many eggs as it could fall into place to intercept Peter's seed.
