Bianca, a white-haired woman with a swiftly growing cock

Bianca had been going to get a drink of water when she heard the first scream. It didn't sound like one born of pain, rather like one released in the throes of ecstasy. Not that the overweight, white haired girl had any experience with such things outside of porn. She walked towards the repeating sound as quickly as she could, surprised by just how far the sound had carried. Finally, she rounded a corner and saw who was making the sound.

Hunched over in the hallway was her friend and neighbor Elise. Bianca knew the younger girl was around in the bunker somewhere, but hadn't wanted to talk to her in the face of her parents being caught up in whatever was going on outside. Now, she was wondering how someone could change so much. Elise had never been particularly busty, but now her tits were huge, massive wobbling globes that would give any man an instant erection. Though the screaming girl seemed to have that covered too, if the foot long dick emerging from between her juicy thighs was any indication.

Before Bianca could do or say anything, Elise's screams became even louder, her entire body convulsing as a long streak of cum shot from the tip of her cock. Bianca couldn't bring herself to do anything but watch as it flew through the air and landed squarely on the twenty-one year old's face and fatty breasts. Heat immediately bloomed in the white-haired woman's body, a bright flush painting her cheeks as her legs threatened to fail her. She was suddenly aware of an acute emptiness between her legs, one she felt all too often before she squeezed her dildo inside herself. She was slowly regaining control of herself when another thick rope of hot jizz hit her face, a portion of it falling into her open mouth. Her eyes instantly rolled into her skull and her muscles seized as changes rolled through her.

The overweight girl felt her body lightening, rolls of fat that appeared over years disappearing in seconds. Her hands flew to her waist as her belly became what she had always dreamed of, slim and indescribably sexy. Her already large breasts and ass toned themselves, going from loose saggy blobs to firm globes that held their perky shape. She slapped herself on the ass, watching the bubble butt jiggle and ripple.

"I'm beautiful. I'm fucking OH SHIT!!" Bianca's legs buckled again as an intense pressure pushed at the front of her crotch. It didn't take her more than a second to realize what was happening and she moaned with anticipation and desire, squeezing her new tits. In moments, her new cock was forming, replacing her clit and shooting out to a formidable length. Weighty testicles dropped down just behind it and in front of her still gushing vagina.

"Oh yes, look at this fat cock. I'm so fuckable, in every sense of the word. I can't wait to shove this thing in some girl's pussy. Not you though, you look like you're already plenty busy." Bianca looked down at Elise, who was staring back at her with hungry eyes. "Don't worry though, I wouldn't leave my friend in the lurch like that." She walked towards the futa laying on the floor, her white hair bouncing against her back in its braid.

"Cock, fuck me, please. I need it. I need more cum," Elise begged, her red hair everywhere as she reached for the other woman's hard shaft. Bianca quickly pushed her hand away before she could touch her hard length.

"Ah ah ah, none of that for you. Maybe I'll come back and give you a nice taste, but I think this will do nicely for now." Bianca grabbed her friend's oozing shaft and gave it a quick pump, drawing more fresh sperm to its tip. "Open wide," she said, forcing the redhead to bend, and bend, and bend, until she was practically folded in half. Elise's own hard dick was right in front of her, the smell of her own cum too enticing to pass up. The younger girl slowly opened her mouth and gave a tentative lick, entirely unprepared for the blast of pleasure that shot up her spine. Combined with the taste of more jizz, Elise was helpless to resist as she wrapped her lips around her own cock, sucking more of the delicious fluid out of herself, trapped in a loop by her own body.

Bianca watched as Elise picked up her pace, sucking harder and harder on her own shaft until she came and flooded her mouth with pearly cum. The blissed-out girl moaned around herself, pinching her massive breasts on their erect nipples to further her pleasure. No sooner than she had swallowed her load, she was shooting another between her swollen lips, her mind regressing further into endless rapture.

Bianca couldn't help the manic giggle that slipped out of her mouth as she watched Elise consume herself, both physically and mentally. Her own futa cock throbbed at the sight, tempting her to shove herself into her friend's gaping cunt and fuck her until they were both drooling messes. She barely restrained herself though, already decided on who she wanted to be the first to feel her rod. Turning away before she could be tempted again, Bianca made her way deeper into the bunker.
