As the two women ballooned past 650lbs, Kim felt a strange sensation inside her now J-cup breasts. It felt as if some sort of pressure was building up inside her chest and it was slowly becoming painful. As Kim's gut formed a third roll and Shego developed her third chin, Kim had begun to groan from the pain in breasts. After a few seconds of this, Shego began to get annoyed.
"Oh put a lid on it Princess," Shego snapped at the girl beside her, thinking she was groaning solely about the loss of her figure, "It may suck beyond belief to watch a lifetime of training to go down the drain, but this doesn't even make the top ten on the list of things that have happened to either of us."
"But it hurts Shego. My breasts feel like they are gonna explode," Kim whined out as she clutched at her nipples in a vain attempt to make the pain go away.
"Uh, fine," groaned Shego, "If it hurts that much, I will see what I can do to help."
Having said that, the exasperated woman let out a small grunt, and managed to heave her now 700lbs body upwards into a standing position. Shego slowly waddled over to Kim, and knelt next to her. As Kim started to blush, Shego reached out and started to massage Kim's breasts. Kim immediately moaned in pleasure as some of the pain disappeared under Shego's expert touch. However, the pressure she was feeling continued to increase, and the nipples of her now K-cup breasts stood hard and erect. Shego noticed this development and blushed slightly before smirking and trying to embarrass Kim even more.
"Aww, is the big fat crime fighter getting hard for the villain?" Shego teased, "What happens if I just squeeze these really hard? I bet that'll get you really screaming."
Shego got what she wanted as Kim blushed furiously although not for the reason Shego thought. Kim was trying and failing to keep naughty images of her and her archenemy out of her head. Then Shego made good on her threat and gave Kim's swollen nipples a hard squeeze.
Almost immediately, the pain and a great deal of the pressure left Kim's body, and Shego was abruptly splashed with a thin spray of milk from Kim's porn star sized tits. As the spray turned into a thin trickle, Shego instinctively swallowed the creamy liquid. Although she somewhat enjoyed the taste, she couldn't let Kim get away with this without more teasing.
"Really Kimmie, your making milk now?" Shego taunted, "Guess I'll have to call you Kimmie-cow from now on."
Unknown to Shego, this had eroded the last of Kim's self control over the lustful thoughts in her head.
"Damnit Shego, squeezing isn't enough," Kim shouted, "I need you to suck them, please suck my fat tits."
With this, Kim suddenly stood up and forced a very startled Shego onto her nearly love seat sized butt. Shego only had time to gasp in surprise before Kim forced her mouth open and stuffed both nipples inside before pressing her twin orbs into Shego's face, and the rest of her body into the green skinned woman's flab, lustily groping as much pale green ass fat as she could while pinning Shego under her.
With 700lbs of heroine now pressing sown on her, Shego had very little choice but to comply with the redhead's demand, and started to suck and fondle her breasts, although one hand moved to grasp Kim's own sizable ass nearly on its own.
Despite her anger and shock at being so suddenly molested, Shego had to admit that Kim had very nice breasts. The giant globes of flesh had the natural heft and thickness that Shego preferred in her occasional female lovers. Kim's milk was also exceptional, with a rich creamy taste and a thick heavy texture that blew anything Shego had gotten from a store out of the water. Shego began to moan slightly from the wonderful taste, and the heat rapidly building up in her body as Kim's erotic behavior continued.
Unknown to Shego, Kim's milk was amplifying the effects of the nerve gas that still filled the room, as she was now fattening faster than Kim. While Kim had just passed the 750 mark, Shego had ballooned to a staggering 800lbs. Her pale green breasts now matched Kim's at M-cup size, but her belly had now passed Kim's by a decent amount, and her ass was nearing the size of a three person couch.
While Shego was unaware of her accelerated gain, as any additional heaviness she felt was mentally assigned to Kim's continued weight gain while lying on top of her, Kim was fully aware of how rapidly Shego's weight was exploding, and how she was grabbing more flesh with every squeeze. Kim moved one of her hands higher so that she could start grabbing at Shego's belly. As she caressed the engorged sphere of fat, she felt her body slowly get pushed off the ground, as Shego's gut was lurching forward with every gulp of milk. Milk which was sadly running dry.
As the milk entering Shego's mouth slowed to a trickle rather than being pumped out full force, Shego's hands left Kim's topmost curves and moved to caress the redhead's gut. At the same time, Shego removed her face from Kim's breasts, her gaze lingering on the large orbs and the cleavage between them before moving up to Kim's plump, almost beet red face.
"Well," Shego started, "I certainly wasn't expecting that kind of attention from you of all people, pumpkin."
"You will find that I have a lot of attention to give," Kim said in a sultry voice, "Especially to someone who sounds so damn sexy when they are drinking."
With that, Kim forces herself back onto Shego's belly, and initiated an aggressive kiss, claiming the green woman's plump black lips with her own red ones while her hands wrapped Shego's back and pulled against her back rolls to keep her in the kiss.
'Damn, I thought Kimmie was an innocent little girl,' Shego thought to herself as Kim began to grind against her while deepening the kiss, 'But I guess she did choose to be a high school cheerleader, so that shows what I know about judging character.'
A second later, Kim released Shego with a soft "mwah" echoing through the abandoned base.
"Finally," Kim said as she stared into Shego's eyes, "I've been wanting to do that for over a year now."
"Wha, when did you?" Shego mumbled incoherently as she began to get lost in a lusty haze.
"Oh Shego, I'm going to show you all the things you've made me do to myself over the time I've known you," Kim said as one of her hands slipped between her legs.
It was Shego's turn to blush a brighter green upon hearing the things Kim was promising.
"My only problem is," Kim paused, "It doesn't seem fair for you to be bigger than me. Time to see if that is fixable."
With that last comment, Kim's mouth latched onto one of Shego's engorges beasts and began to suck hungrily.
