Mary-Jane and Peter descended from the web they'd been stargazing in, landing gracefully on the ground. She let go of Peter as they began walking back to his moped.
Not too far away, a small meteor had landed. Out of the steaming rubble crawled a small oily creature. A black blob with dozens of tendrils it used to crawl towards Peter and MJ as they slid on their helmets and jumped onto the moped.
The symbiote skittered towards them rapidly, dashing through the leaves and foliage until it leapt onto the licence plate just as they pulled off. Once on, it slowly crept up onto MJ's back, holding onto her coat tightly as they sped off.
After the journey home, Peter waved MJ goodbye as she approached her apartment building. She'd hoped Peter would have joined her, but he said he had something else to sort out before he finished for the night.
Peter soon sped off, leaving Mary-Jane to her evening. She sighed as she saw him drive down the street, eventually disappearing. Unbeknownst to her, the symbiote waited patiently on the back of her coat as she went inside.
Upon reaching her apartment, she was met by the landlord, who stopped to ask if she had seen Peter, determined to get his rent long before it was due; nevertheless, he persisted despite the issues he knew Peter Parker had.
MJ slid off her coat and went into the kitchen, confronted by the sink full of dishes she hadn't cleaned from the night before. She finished them off as the symbiote dropped onto the floor, landing with a tiny thump.
Creeping across the floor, it skittered quietly towards the foot of her bed, oozing beneath it and sliding out of sight just in time as MJ strode past, starting stripping off, ready to call it a night.
MJ slid into bed moments later, getting comfortable above the sheets, feeling a little too warm to be snuggled beneath them just yet. She switched her bedside lap off, plunging the room into darkness.
After a few minutes, the symbiote slowly oozed out from beneath the bed, considerably larger than before, as it began creeping up towards her.
Stretching out two tendrils, the symbiote reached for her legs, sticking to her feet like glue as it began to grow rapidly, spreading up her legs.
MJ stirred as she started to feel a warm sensation running up her thighs. The black oily tar absorbed her underwear, oozing steadily up her waist, covering her perky butt and coochy.
By the time she awoke, it was already too late. The symbiote spawned more tendrils as it spread to her fingers and up her slender arms, trapping her in place as it bonded to her body.
MJ gasped, feeling the strange black tar spreading over her shoulders. Before she could react, the symbiote covered her face, completely encasing her in its thick sticky matter.
She lay thrashing around on the bed, her screams muffled by the symbiote. Her clothes melting away, consumed by the symbiote as it formed on her body.
Conforming to her slender physique, the symbiote grew extra goo to bulk out her body. Her breasts swelled to twice their normal size, gradually forming into a sleek hourglass figure as her ass expanded in unison, bulking out her hips and thighs to allow for massively enhanced strength and mobility, her arms, stomach and legs toning up as it took over her body.
Her butt sunk into the bed as it grew considerably, her chest getting heavier by the second as the symbiote finished adapting itself to her body, wrapping everything up in the perfect attire. Using her memories of Spider-Man, it formed a sleek, jet-black catsuit with a large white spider across the front and back, mimicking shiny latex as it took shape around her succulent and well-toned figure.
Eventually, her panicked thrashing subsided as the symbiote integrated with her mind and body, starting the process of slowly converting Little Miss Mary-Jane into a permanent host. Within a few days, the two would become inseparable.
MJ gasped softly as the symbiote uncovered her face, allowing her to breathe again. She lay on the bed panting, gathering her now greatly enhanced senses. Gulping as she looked around her dark apartment, too afraid to move, unsure if she'd just had a nightmare or someone was in here with her.
