This strange erotic story tells you about a teenage boy named Nicky and his lovely big-tittied girlfriend named Gena, who gets transformed by her boyfriend's amulet from the old magic shop that turns her into an ideal mom and has sex with. Not only that, he will continue to change her any moms or MILFs he wants to fuck.
My name is Nicolas O'Donnell, but most people call me Nick or Nicky for short. I'm just some average handsome high school teenager who finished the boring semester and enjoys the summer with my lovely girlfriend, Gena. Gena and I have been friends since childhood, and we've been dating for almost 6 years now. Gena is a cute, pretty, smart, outgoing, and sexy girl in school. Not only that, we've been hooking up with each other ever since our parents were around, we even found a spot where no one disturbed us, and we were enjoying our time together like playing games, studying each other, and having sex. Our relationship had been great, but lately… something wasn’t right. Not our relationship, we're still together.
Ever since I found that weird amulet at the old shop called "Spell R Us", I couldn’t stop thinking about it, as I was curious and decided to buy it myself. The owner is an old man who sold it to me, had winked and whispered, “Ya know, kid. I never thought that one day, someone would buy this. This amulet will give ya whatever ya want, kid.” As the old man replied, honestly, I didn’t believe in magic—until now.
When my mom and dad are on their honeymoon, I get to invite my girlfriend to come over to spend our time together. For a while, Gena stretched across my bed in nothing but an old band tee and panties, her blonde hair splayed over my pillow. Her body was already incredible—those big E-cup tits spilled out the sides of her shirt, her waist curving just enough to drive me wild. But as I clutched the amulet in my pocket, staring at her while pretending to scroll on my phone like I was texting my friends. I remember what the old shopkeeper said to me, and I was about to try it out, so I imagined my girlfriend, Gena, being someone. Someone… older, old enough at my parents' age. Someone with T-cup tits that defied gravity, hips that swelled into a perfect hourglass, a voice like honey and motherly warmth.
“Babe, why you starin’ at me like that?” Gena giggled, tucking a strand of hair behind her ear. "Is there something wrong?"
“Oh no, it's nothing, Gena. I'm just admiring you and... um... enjoy the view,” I lied, my fingers continued squeezing the amulet tighter as I tried to focus on my s. “Here goes nothing, c'mon, change for me,” I thought, unsure if it was even real.
Then, she twitched.
A weird little shiver ran through Gena’s body. She frowned, rubbing her forehead. “Ugh,... what's happening to me?... why... do... I feel kinda… dizzy...”
I held my breath as I realized the moment of transformation had begun.
Her fingers drifted down, grazing her own breasts absentmindedly, and—holy shit—were they… swelling? Just slightly, but I could see them pushing against her thin shirt. The curve of her waist seemed to soften, her hips widening ever so slightly beneath the sheets.
“Nicky, ba... baby,” she murmured, her voice already deeper, huskier. “I don’t… I don’t feel like myself.”
I swallowed hard, my cock already pressing against my jeans. “It’s okay, Gena,” I whispered, crawling onto the bed beside her. “You’re just gonna be fine.”
Gena’s eyes fluttered—and changed. Her once-playful gaze turned softer, warmer, filled with an easy maturity. A crease formed between her brows, then smoothed out. Her lips—full and painted a soft pink before—turned a deeper shade, her mouth parting slightly as a strange, dazed recognition flickered across her face.
“Nicky… sweetheart?” she murmured, voice thick with sudden affection.
My heart pounded with excitement. It was working.
I reached out, letting my fingers brush her side—and gasped. Her skin was softer now, silkier, with the faintest touch of age smoothing over her. Her tits had risen higher, fuller, heavier, straining against the fabric of her shirt.
“Oh... my... god,...” I whispered, unable to stop.
She blinked slowly, then smiled—a warm, maternal smile—before her hand drifted up to cup my cheek. “Baby, you look tense,” she cooed. “Did you have a hard day?”
I shuddered. She thought, acted, and sounded like she was my mom all of a sudden.
But her transformation wasn’t done yet. The amulet was burning in my pocket now, pulsing with energy as her body shifted. Her E-Cup tits swelled impossibly larger, her shirt seams groaning before finally snapping, buttons pinging across the room as those massive T-cup mommy milkers spilled free.
“Oh my!” she gasped—her voice now deep, velvety—and looked down at herself. Her fingers traced over her new curves, her huge areolas darkening, her nipples stiffening. “Ohhh… I forgot how big I was.”
Her stomach had softened into a perfect little pooch, leading down to thickened thighs that could smother a man. Her face had aged—just enough—to show laugh lines, motherhood written in every new crease. Her blonde hair had darkened slightly, now streaked with a few silvery strands, swept into a loose, messy updo of a dirty blonde.
And most of all—she looks entirely different from what she was, and believed she was my mom.
Geraldine.
My new mommy, whom I always dream about.
Her eyes flicked down, spotting my raging hard-on, and she tutted—like this wasn’t the first time she’d caught me like this. “Nicky, really?” she sighed, shaking her head. “You know you shouldn’t be getting all worked up like this.”
I couldn’t take it. My hands shot up, groping her monstrously huge tits—so much bigger than before, so perfect—and she gasped, her cheeks flushing.
“Nicky! My, what are you doing to your mom, sweetie?” Gena,... or rather, Geraldine scolded, but she didn’t pull away. She's surprised when my hands reach out and cupping her massive tits. I knew—this was so much better than Gena. But I still love my girlfriend. Right now, I just want to enjoy my time with my "mom".
Gena gasped, her body felt sensitive to my touch. "Nicky... sweetie... you... you can't do that. I'm your mom."
I smiled, my thumbs brushing over her hard nipples. "I know, mom. I'm sorry, but I couldn't help myself."
Geraldine moaned, her eyes fluttering closed as my hands explored her body. I leaned down, my mouth capturing one of her nipples as he sucked it into my mouth. Geraldine cried out, her hands grasping my head as she held mine to her.
My hand slid down her body, slipping between her legs. I could feel her heat, her wetness, even through her panties. I hooked my fingers into the waistband, pulling them down and off her legs.
I sat up, straddling her hips as I looked down at her naked curvaceous hourglass body. My cock was hard, throbbing with need as I quickly shed my own clothes.
Gena looked up at me, her eyes filled with a mix of lust and confusion. "Nicky... baby... w... we can't do this. I'm your mom. And... what if your d... dad gets home and sees us like this.."
I smiled, my hands sliding up her thighs as I spread her legs wide. "I don't care, mom. And you know, even if you're my mom, I still love you."
With that, I slid my cock into her, her warm, wet pussy enveloping him completely. We both moaned, our bodies moving together in a dance as old as time.
Geraldine's massive breasts bounced with each thrust, her nipples hard and begging to be sucked. I leaned down, capturing one in my mouth as i continued to fuck her, my cock sliding in and out of her at a relentless pace.
Gena moaned, her head thrashing from side to side as she cried out, "Nicky... baby... we... have to stop... what if... someone... would..."
The more she moaned, the more horny I got, and I wasn't listening. I was too far gone, as my body was overcome with lust and desire. I fucked her harder, my cock pounding into her as I continued suck at her massive tits.
Geraldine's protests turned to moans of pleasure, her body shaking with each thrust. But she still tried to resist, her hands pushing at my chest as she begged me to stop.
I looked up at her, my eyes filled with determination. I captured her mouth in a searing kiss, my tongue sliding between her lips as I silenced her protests.
Gena-Geraldine moaned into my mouth, her body melting against mine as she gave in to her desires. When I finally pulled away, she looked up at me, her eyes filled with lust and need.
"You know what, baby," she murmured. "I think mommy love it, now fuck your momma like a slut."
I grinned, my cock throbbing with triumph. I sat back, grabbing her wide hips as I slammed into her, my cock pounding into her at a relentless pace.
Gena-Geraldine cried out, her massive breasts bouncing with each thrust as she moaned, "Yes, baby. Yes! Fuck your momma. Fuck me. Fuck me like a lover."
Our lovemaking was intense, our bodies slick with sweat as we moved together. When we finally cum, it was explosive, our bodies shaking with the intensity of our orgasms.
I collapsed on top of my ideal mom, Geraldine, my cock still buried deep inside her. She wrapped her arms around me, her hands stroking my back as she cooed softly to me.
"That's my boy," she murmured and giggled.
I grinned, my cock already hardening again at her words. I looked up at her, my eyes filled with love and lust.
"I love you, mom," he said, his voice filled with sincerity.
Gena-now-Geraldine smiled, her eyes filled with love. "I love you, too, sweety."
As we lay and cuddled there, our bodies entwined, I knew that this was just the beginning of my exciting transformation adventure. Gena might no longer just my girlfriend, she becomes my ideal MILF that I dreamed about. Maybe this transformation wasn't so bad after all. Perhaps, I could change her back, and then she doesn't remember any of it, or I could keep her this way until my parents get back.
