She gets what she asked for.

The patrons of the shopping center screamed and panicked at the sight of the terrible arachnid monster lounging in the center of the place. Fleeing for the exit, they all found themselves locked in and the doors barred by thick webbing that recoiled any attempts to break the doors down. Then their panicked cries turned to screams when the ceiling was torn open and another massive creature tore itself through and landed heavily on the grocery store floor in front of the smiling Jessica Drew.

There was no flirtation between the two as Peter hoisted her legs up and speared into her pussy in one thrust, making Jessica swoon with delight as she wrapped her legs around his ide waist and tangled her arms in his, their bellies pressed together as he immediately began to buck and thrust against her. "Hmm, welcome to the pack Jessica." Grunted Peter as he thrust hard and deep into the venomized monster woman. "You're gonna LOVE it! All you get to do is eat and fuck as much as you want."

"Hnnmmmmph... Tell me more!" She cried out, arching her back and thrusting out her chest where one of her breasts were instantly captured in his fanged lips.

"Hnnngh... Raaarrrrrgh! I'm... I'm gonna pump you so full you'll be immobile with my eggs."

"Pro... Aaahh... Promises... Promises..."

"We are gonna eat and grow until we RUN this place, and then... Then... TheaaaaaAAARGH!" With a bellowing roar, his balls tensed and flooded Jessica's womb with his cum, making the female venom scream and cry out as her own orgasm blasted through her psyche. Chuckling and moaning, the two nuzzled each other as Jessica moved and turned herself around onto her hands and knees, shaking her massive ass invitingly and quickly being rewarded with Peter mounting her from behind. "Our nest will be crowded with eggs just waiting to hatch, Hnnngh... This city's gonna be a crater when we're done with it."

"YES... Eat and FUCK until there's nothing left but us."

Another roar echoed out as the two reached another climax, causing Jessica's swollen belly to grow larger and rounder, all while she stuffed herself with what was around her. The Spider-Woman was gone now, replaced with a feral arachnid monstrosity that only wanted to grow and indulge, and the idea that she could breed more of their kind excited her to no end. This new uninhibited version of her wanted to experience this all to the fullest. Looking to the screaming, panicking people who were forced to watch on, Jessica licked her lips. Wondering what her new prey will taste like.

Getting up to her feet, she stomped over to the crowd like they were frightened mice and snatched them all up one at a time with her many hands, opening her jaws wide and shoving them all down to swallow whole. Peter soon joined her, eating who and what he wanted as the pair ate and grew larger. Jessica could feel her backside grow with each bite, her arms and legs growing thicker with bone, muscle and fat. It didn't even surprise her that her head hit the ceiling after clearing out the building. What did however was when she squinted her eyes after they became blurry and rubbed them, only to open them again and find she now had four. Gasping, a growth formed just above her massive ass cheeks, swelling and filling out like a third cheek to add to her rump, just as it sprouted a pair of what felt like fingers she could move and flex. Spinnerets.

Laughing with a toothy grin, she turned her attention to Peter who grunted and leaned against a broken wall as he too went through more changes, his own spinnerets forming as he sprouted additional eyes and a pair of prehensile fangs behind his toothy jaws like mandibles. Now more arachnid than ever, the pair looked themselves over with bemused curiosity.

"Hmm... I like this!"

"Oh yes, I wonder how my mates are handling the others."
