Randy and his girlfriend hung out in her mom’s house, enjoying the last hour they had before she got home. When out of nowhere, Lucy pulled out a pair of her panties and presented them to Randy.

“I have an experiment I’m trying to run, and I need you to put these on… please?”

He gave her a perplexed look, “What do I get in return?”

“Oh you know what you’ll get!!”, she slapped his shoulder playfully as he got up. Randy got nude from the waist down, and slipped the panties on. A pang of horniness rushed through him, and he got hard instantly. He saw the panties squeeze around his cock, and let out a moan as it started tingling pleasantly. Then Randy watched in shock as his penis slowly started receding into his body, and the arousal he felt intensified throughout his body.

It was now that Randy realized his tee shirt was tightening up and squeezing his body, shrinking it like his dick. He was now a full foot shorter than he had been, and could feel fat being sucked out from every part of his body. He whimpered in ecstasy as the fat surged into his growing breasts, and expanding ass. Extra fat shot into his thighs, giving him a thicker curvy figure.

Lucy watched smugly as Randy’s panties finally flattened against his crotch, peeling them back a bit from his sticky folds. Then she plunged her fingers deep into Randy’s pussy, accelerating the changes and bringing Randy to the edge of sanity as cum gushed from between his tight lips. His breasts were now full, and he started to feel an aching in his loins. Lucy backed away and giggled as Randy moaned and grabbed his crotch, searching the room frantically for something to ride.

With nothing around, Randy started humping the air, eventually finding a pillow. He was ravenous, stimulating his clitoris with each thrust into the pillow. Lucy watched giggling, picking Randy’s shirt up and tweaking his nipples. Stuck in a hypnotic state, Randy continued fucking the pillow with his eyes closed.

“You’re gonna be my sexy little sister Raven, the biggest bimbo in school! We do each other’s makeup, gossip, shop and even share boys!!

Our mom is the hottest, sluttiest milf in the neighborhood. We watched her bring guys over nightly, and even started joining in when we were both eighteen.”

As Lucy continued changing his past, Randy could feel his memories fading into nothingness. No longer was he the start quarterback, going out with the head cheerleader. His sister was now the head cheerleader, and Raven planned on joining the squad next semester. She just needed to get better grades, and planned in fucking all the teachers to get it.

She remembered all the sex she watched her mom have, transforming her views on the world in general and seeing everything as a sexual opportunity. Raven forgot her old name, and could barely recall her old self as anything more than a past conquest. She shook her head trying to stop the changes, but then Lucy grabbed her face and started kissing her.

All the fight left Raven and she let Lucy slip her out of her panties, before leaning in and kissing her lips. They sat on the couch naked, making out for hours. Each touch of the lips bringing Raven deeper into her new life, Lucy breathed new ideas and memories into Raven. She now needed to be filled, her pussy ached and felt empty without cock.

Every little flick of the tongue changed Raven, her pussy tightened as her body slimmed down some more. She now was able to ride cock like a champion, the muscles necessary becoming stronger on Raven’s sexy body. She was the perfect size to be thrown around by any guy she would be riding, and a playful giggle came out as her clitoris became pierced.

Raven vividly remembered her mom and sister having to convince her to stay home for an orgy, because Raven was already going to a club with a bunch of guys.

She fondly recalled conceding to them, and inviting all the club guys over for the orgy. The three girls had all their holes filled, and Raven got wet just reminiscing about it. Raven had so much sex, she could blind taste cum and know who’s it was. She licked her lips as she remembered the salty taste of being covered in cum, feeling loads shot onto her skin had made Raven orgasm. She especially loved when there were multiple guys doing it, the stream of cum into her open mouth never stopped. Every second her memories intensified and became even more sex driven, Raven eventually totally gave in to the change.

Just then Chanel returned him from work, giggling upon seeing her daughters making out with each other.

“You’ve clearly changed your boyfriend already…

I can’t even remember his name anymore!

I told you to wait for me, I would’ve made those cute little boobies so much bigger!!”

“Wait…”

“Shush Raven, don't worry your slutty little head…”

Raven became much calmer, instantly feeling the worry leave her when mommy told her it should.

“Like mommy, what should I totes not worry about?”

Chanel’s eyes glimmered, “I don’t want you worrying about anything ever again Raven, except how to get yourself more cock to suck and fuck.”

Raven became even more aloof, and started drooling thinking about all the boys she knew she could hit up for blowjobs right now.

“Alright girlies, time for dinner!”

Chanel got up on the bed, and both Lucy and Raven got up with her. Not hesitating for a second, before gripping their mother’s nipple and sucking.

“I changed my husband into my daughter, and then she gets a boyfriend. What am I to do?

Oo! No biting honey. When was the last time you breast fed??”

Each sip from her mother’s nipple made Raven more horny, and delve deeper into her new reality. The same was happening to Lucy, her mother smiled watching both former men drink from her breasts.

Lucy had been transformed weeks ago, her mind was mush compared to what it used to be. Countless hours of drinking her mother’s breast milk, and being eaten out by her magical mouth. Lucy was so deeply entrenched in her mother’s fantasy, she didn’t even care that her new boyfriend was now her little slutty sister.

“Alright Lucy, you eat your sister out. You have my magic inside you, so make sure to give Raven as much as you can.”

Chanel pushed Raven back into a lying position, where she lay moaning as Lucy began eating her out. Chanel then wrapped a leather strap around her waist, closing it around her back and immediately moaning erotically. Raven watched with anticipation as something started coming from her mom’s tight lips, and continued growing into a phallic white object.

Raven drooled as Chanel stroked her new dick, before penetrating her daughter’s dripping pussy.

Raven felt Lucy moan into her as her mom thrust in and out, creating a path for magic to go from Chanel’s cock into Raven’s body. The magic flowed from Chanel’s cock, pulsing through Lucy as she ate out her sister. And Raven felt it trickle into her, making her much more sensitive. Her skin tingled as Lucy licked her folds, each one bringing new sensation to Raven. It started getting harder for her to think about anything besides orgies with mommy and Lucy.

Raven smiled blissfully as she heard the doorbell ring, and guys’ voices behind it. She sucked on her fingers as she thought about having her holes filled, and getting shot after shot of cum inside and outside her new sensitive skin.
