The next day, Cindy and Gwen have caught up...

The next morning, Peter sat up in bed, practically rolling over and finding the distance between the bedframe and the ground wasn't to far when he ended up on his hands and knees. Getting to his feet, Peter groaned and scratched at his thigh, making his way out of the bedroom one shoulder at a time to head to the bathroom. There was no mistaking it, he was getting bigger. As the days went by, his and MJ's shared home felt more and more like a shrinking doll house. He even found he needed to duck to enter the door frame of the washroom as she lurched in front of the mirror and caught his reflection.

He was still in his venomized state and likely had been that way the entire night with him and MJ together. Giving himself a look see, he turned his head back and forth and opened his jaws wide, not too dissimilar to the mouth of a piranha but with a long prehensile tongue. His hands were clawed, as were his feet, and looking further down at his body, he stared at his bulbous chest and prominent gut hanging in front of him, along with the foot and a half long flaccid cock that hung heavily between his legs along with the pair of oranges he had for testicles.

"Like the look?" He heard Venom ask in his head, prompting Peter to close his mouth and smirk. "It was your lover's idea."

"Never thought I'd like having fangs, something tells me my dentist would hate me for that though." Pulling back the symbiote, Peter watched as it left his body completely nude, but his dimensions remained the same as black oily skin peeled back to reveal pale skin with thick hair over his chest arms and back, along with his legs and the underside of his gut. "Still... This isn't too bad."

"Then you like." He heard MJ from behind, the large woman smiling at the door as she squeezed herself into the washroom and pressed up against Peter from behind, smiling over his shoulder while letting her hands roam over his arms and gut. Her hips and thighs brushed against the door frame getting in, and with the two of them in the washroom, the space was very cramped, making Mary Jane smile more impishly. "Hmm... I like it when we're cramped together like this, the sensation of being too big."

"Do you wanna hold off gaining more?"

"No!" She smiled, letting her hand grope at his cock and give it a pump. "And let this one eyed monster shrink down? No way Tiger, I want you BIG! Big and gruff and heavy, just for me."

"Heh, okay, got to admit, the added curves are pretty good looking on you too." turning around, Peter found himself pressed against the wall as MJ made out with him, moaning into his mouth as she pressed her breasts and belly against his chest and gut, her hand never leaving his cock as she pumped him rigorously. Pulling away at the last minute, MJ fell to her knees and clasped her lips around Peter's hardened erection, just in time to unload a deluge of seed down his lover's throat. Grunting and panting while leaning against the bathroom sink for leverage. Shuddering, he looked down at his tall, curvaceous lover who sat up and swallowed his load hungrily.

"Wha... What was that?"

"Breakfast... Have a good morning lover." Getting up to her feet, she turned around and made her way out, intentionally pretending to get her hips pinned in the door way and looking over her shoulder to grin, seeing his erection bob and drip at the sight of her thick thighs and massive rear just as she pulled herself free.

Blinking and shaking his head, Peter turned around and went to cleaning himself up, he worried that they were getting too big for convenience but... Sex had never been better, and he was starting to enjoy being large for a change. Getting cleaned up and willing the symbiote to appear as clothing, Peter squeezed his way out of the washroom and out the front door, waving back to his girlfriend as she waved back from the bedroom.

Once he was out of sight, MJ purred at what was coming next.

2 hours later...

Coming..." Purred MJ, making her way towards the front door, smiling as she felt her thighs rub together in the act. When she opened the door wearing a black button t-shirt unbuttered and tied at the front with a pair of matching denim shorts, the hefty woman smiled at her visitors. The two women standing in front of her panted, their faces flushed with arousal. Stepping back and outstretching her arms, it didn't take long for Gwen and Cindy to storm their way inside and slam the door behind them.

Pinned against the wall by their combined bulk, the two women made out With MJ, their hands roaming over her body as she willed her symbiote to peel away and made her nude. Wrestling her tongue with Gwen's when their lips collided, the two women moaned into each other's mouths before separating and switching places, giving Cindy a turn to make out with the red haired woman while Gwen sniffed at her neck and licked at her ear. Snaking her hands around to grab handfuls of their thighs and ass, MJ smiled into Cindy's lips. Both women had over the course of the night eate and grew to become three times their original mass and it showed on their tall ample frames. Gwen swooned when her melon sized breasts mashed against the women in front of her, their bellies pressed and their thighs rubbing against each other. Cindy reached down to grab Mary Jane's hand and brought it to her bloated belly, then to her ass as if to how off her new expanded curves and how far she had come.

"Hmm, you've both grown SO much. I'm proud of you both."

"So hungry... Had to eat, had to grow..." Husked Gwen, burying her face in MJ's cleavage and clasping her lips around one of her stiff nipples.

"Become big and FAT enough for you... For Peter."

"I NEED him inside me!" Mewled the blonde, pressing her thigh against Cindy as they quickly made eye contact and made out at first sight. Whatever impulse control they once had was gone and likely gone for good. Hoisting her breasts in her hands, Mary Jane waited for them both to turn their attention to her and was pleasantly surprise to have them both bite down at her nipples.

Biting her lips, MJ twerked her ass against the wall as she felt the two suckle at her tits, their tongues swirling around both stiff nubs. "Hmm... Welcome to the pack girls! Come with me..."

Making her way over to the bedroom with the two walking behind her, she could still hear them whimper with lust, with Cindy tracing a finger down Mary Jane's back and caress at her wide rear, making the tall and plump woman smile. Once they were inside the bedroom, MJ stood over the sight of the king sized bed, flattened and broken with its legs splayed out from underneath and the mattress springs poking out of the sides.

"We need a new bed if we're going to be sharing Peter, any thoughts my sisters?"

Pressing up behind Mary Jane and leaning her head over her shoulder, Cindy snaked her arms around MJ's body to caress her belly fat and cup at her large breasts. "But do you NEED a bed? We can fuck anywhere, I bet even the floor would feel good."

"On the floor? Like some animal?"

"Yeah! I just feel so... UGH..." Grunted Gwen, tossing her hair and twerking her hips. "I just want him to dominate me like a bitch in HEAT! Who cares about a bed if we're gonna be BIGGER than the bed? Bigger than the BEDROOM!"

"Mmm, I like the way you think sister, and you're right. Why waist on HUMAN comforts? We're wild, primal and pretty soon we won't fit in this tiny room anyway." The mental image of the four of them growing big and fat enough to threaten the walls from bursting turned on the red head to no end. "This isn't a bedroom... It's a DEN! And I think it should be broken in."
