Heather is stopped at the door

Heather tried to run after Jenny as the door to her room slammed shut, only to be sent to the floor with a gasp as she accidentally rubbed her still-stiff cock, the sensation momentarily overwhelming her. She stood up more carefully and pulled the door open, only to run right into someone.

"My oh my, what's this? Looks like the little girl's sporting a big package," a warm voice said. Heather took a step back and saw that the person she had run into was their neighbor, Monica, a beautiful MILF of a woman just entering middle age. Her long blonde hair contrasted with her darker skin, speaking of some mixing of genes. The alluring shape of her sculpted hips inspired another rush of lust that Heather had to try to **** down, not made easier by her heavily dribbling cock.

"Monica? Please, don't come near me, I'm dangerous. I changed Jenny, I could change you too," the brunette futa said, backing even further away from the mature woman.

"Yes, I saw that. You gave your pretty cousin a big, long piece of meat, just like yours. How did that happen?" Monica took a sensual step forward, slowly closing the door behind her.

"I-I don't know. She...she made me cum, and then she started changing. Just stop, I don't want to infect anyone else."

"What if I want to be infected?" Heather froze, her eyes widening at the implication.

"You...why would you want-"

"You know, your cum could be considered a miracle," the blonde MILF said, striding closer to the nervous younger girl. "I know what Jenny looked like before. Flat, pretty enough, but nothing outstanding. Now she's one of the most beautiful women I've ever seen. She's incredible. And so is the girl moaning out in the hallway. I got to watch her become like you, a thick, busty woman with a fat, juicy cock. Fuck, the amount of cum she splattered across the hallway made me so wet. I saw what she was cleaning up in the bathroom too. More of that thick jizz of yours." Monica finally reached Heather and walked around behind her, pressing her weighty D-cups against the naked girl's back.

"I want to be that sexy, that fuckable. And you can make me like that with just a little cum. Look at you trying to keep it in, I can't imagine what it's like. Though I think I will soon." Monica's hand reached around Heather's body to grab hold of her pumping shaft. The futa barely resisted, now almost looking forward to the bliss of orgasm again. Her walls were breaking down, and she knew that soon she wouldn't care for much else other than the feeling of spurting her thick load.

"My my, listen to you moan, little girl. It must really be something, to have a cock like this. I can hardly wait. But how to do it? I could just give you a squeeze like this and scoop up the mess..." Monica's hand moved quickly, stroking the length of Heather's dick with practiced mastery. Her other hand came up and pinched one of her pointed nipples, the deadly combination making the brunette's balls tighten as another wad of jizz arched out of the moaning futa's bulbous head. "...but that wouldn't be much fun at all. Have you been given your first blowjob yet?"

"Nng-ugh-n-no," Heather grunted, her cock blowing the last of its reserves as her orgasm ended. The dickgirl knew that it was only a matter of moments before the next load was ready.

"Don't worry, I'll ensure you enjoy it," Monica said, turning the panting girl around and going down on her knees. Without a second of hesitation, she slipped her mouth over Heather's cum-covered phallus, creating a tight seal around its head before slowly bobbing up and down the rod.

Heather let out a breathy moan as Monica went to work, her slobber slickening the futanari woman's cock. The MILF was an expert, experience born of many lovers allowing her lips to stimulate Heather to a ridiculous degree. Monica in turn could feel the cum she had consumed already changing her, enhancing her already sexy body. Her pants tightened slightly as her thighs and ass became even more plump, inspiring her to push the enormous cock into her tight throat, her gag reflex gone. Heather's short gasps resounded in the room as a new kind of pleasure hit her system, making her wonder again if she could possibly reach further heights.

Down bellow, Monica pulled on the heavy balls that swung beneath Heather's body, craving the thick liquid inside. Her shirt was straining now, as he D-cup breasts exceeded that size, growing to enormous fleshy orbs. The tall woman could already feel her new cock forming, the shaft of sensitive flesh poking the front of her pants. Unwilling to allow her new self to be impeded, she swiftly shed the offending garment, along with her shirt and underwear, continuing blowing Heather completely naked.

"Oh oh oh oh, it-it's close. Iiii'm closeeee....." the younger woman whined, the now familiar clenching of her testicles heralding her impending climax. Monica's efforts only increased, ready and eager to have her new body completed. The added enthusiasm was more than what Heather could handle and her meaty cock began jettisoning another huge load, this one disappearing down her sexy neighbor's swiftly swallowing throat.

Monica hummed in bliss as more of the transformative semen poured down her throat, quickening her changes and further increasing Heather's pleasure. Monica's tits and ass reached their new full size, both a good deal larger than they had been before. It was nothing compared to the sudden growth of her new appendage, her new cock going from the size of a baby carrot to nearly two feet long. Unused to the new balance of her body, Monica was **** to pull herself off of Heather's ejaculating shaft, splattering them both with the remains of her orgasm.

"Oh, yes, yes, look at me, I'm so fucking MMMHHH!" Monica reveled her new body, running a hand along her gigantic cock. She felt the first bit of her new cum rush up the shaft to ooze out the flared tip, running back down its bronze length on the outside. "Yes, I need more of that. I need..." The new futa quickly grabbed her even more voluptuous breasts and squeezed them together, forming a deep chasm of lush cleavage. She immediately enveloped her new cock with her fat jugs, squeezing the upper half of it between her mountainous swells of titflesh.

"Yeeeeesssssssss~~~" the enhanced MILF screamed, her heavy hanging testicles seizing in the face of the sudden pleasure. In moments, new, hot jizz was exploding out of the newest dickgirl's penis, covering her bronzed tits and the floor in front of her. The woman's body trembled and shook with compounding bliss as her orgasm built and coursed through her, sending shivers of ecstasy blasting through her.

Monica continued to ride out her first orgasm with her new appendage, spraying even more cum around the already coated room. Heather watched in awe as the other woman practically sobbed with with relentless joy and relief. The younger futanari couldn't help the small orgasm that ran through her own body at the sight of the insanely desirable MILF cumming her brains out right in front of her. She couldn't help but wonder what it would be like to feel the same level of mindless pleasure.

Eventually, Monica's peak collapsed, bringing the woman down as well. She laid, sprawled out in a pool of her own jizz, panting as small aftershocks tore through her, her shapely ass pushed up into the air. Heather stared at the meaty flesh with lustful eyes, wondering just what it would feel like to wedge her own shaft between those beautiful slopes.

"See something you like?" Monica said breathlessly, slowly rising to her feet. "You could have me, you know? Just jam that fat prick of yours up my cunt and fuck me senseless. I wouldn't resist, not at all. But you won't because you can't embrace that we're nothing more that horny women with cocks that are begging to fuck something. I already know that and I intend to make full use of this fucking huge cock." Monica stumbled slightly before regaining her full balance, quickly heading for the door. "You have fun with your indecision, I'm going to to find a cunt to pump full of seed."

The exquisitely built woman pulled open the door she had locked not long before, leaving the room to find someone to test her new shaft on, huge even compared to the other futas. The bobbing shaft was the last thing Heather saw of her neighbor before the door closed fully and she came to a striking realization.
