Henry and Camilla were excited to try out this service that promised couples that their sexual experience would be greater than ever before for the rest of their lives. These two were already very horny and fucked quite often, so they were looking forward to see what this hype was about.
Once in the building, they were asked to write down what each of them would like to see on the other. Henry grinned as he wrote down that he wanted his already busty girlfriend to have even bigger tits, be a bit more shy and submissive, be hard-addicted to semen and she could only cum if he allowed it, wanting to tease her to no end with constant edging before he allowed a powerful orgasm. He also desired that both her pussy and anus were always tight no matter how many times they fucked prior and that she’d only wear slutty clothes.
Camilla wasn’t as creative as her boyfriend, but despite what her meek personality suggested, she wanted plenty of upgrades on her lovely man. His 5-inch penis was fun to play with, but it could be bigger, way bigger! She wanted it longer, thicker, more veiny, its testicles matching his new cock’s enormous size. She also wanted huge loads from him, not just enough to match the new member’s size, even larger than that, wanting each rope of cum to be shot as if it came out of a hose. The woman wanted her man to have greater endurance, be even taller than he already was and last but not least, she wanted him to be more dominant.
None of them knew what they wrote for each other, simply chuckling and giggling as they handed the sheets of paper to the staff managing the machine that would allow their sexual fantasies come to fruition. Each of them would step into a chamber before their doors would close and it would fill up with some gray-colored gas.
With the gas entering and transforming their bodies, it was hard to tell what was going on, even their senses were off as they couldn’t really feel their bodies. This would go on for about an hour, the doors would eventually open, the thick gas escaping the chamber to reveal the couples’ new bodies.
Henry and Camilla recovered their normal senses, being able to feel their new bodies, and something was clearly off here. The gas exiting out of the chambers continued to blind them, but Henry could feel something big, huge even, and extremely heavy on his chest. The young man also noticed that his hair was longer.
A foot away from him stood Camilla, her body feeling different but nothing too obvious except for one thing. There was something being stimulated, but what was it? It felt like it was right in front of her and around the same height as her pelvis, something that felt long and hard.
Things became clearer as the gas faded away; however, this would only lead to more surprises and questions. Henry gasped as he, or rather she, saw a giant pair of tits hanging from her chest. She groped them, moaning in a feminine voice as they were incredibly sensitive. The former man could also tell they were indeed extremely heavy and that they weren’t some big boulders glued onto her chest, they were real breasts.
The now pink-haired woman would explore her body further, discovering she now had a tiny dick that was about 1.5-inches long, that her ass was plump and that she had lost height. Camilla was in for a similar shock; in her case, she maintained her big tits and fat bubble butt, although both now looking small compared to her girlfriend’s, what changed was the giant appendage in front of her.
Camilla now had a giant penis, being 1-foot in length and the mere thickness of it putting many men’s penis length to shame. Unlike Henry, she could tell this was what she had written down, the massive cock with thick veins and her taller height were exactly what she asked for her boyfriend-turned-girlfriend.
“W-What happened?!”. “I think… we may have gone into the wrong chambers…”. The naked couple would be provided some new clothes so they could return home. Finding anything that fit Henry, or rather Hilda as she would soon be known as, would be very hard due to her watermelon sized tits and giant dump truck of an ass. Camilla wasn’t as difficult to dress up but it was straight up impossible to find anything that wouldn’t show the beach-ball-sized bulge in her pants formed by her big dick and massive testicles. She hoped she wouldn’t have an erection on the way home.
Camilla would drive, focusing as much as she could on the road in front of her. As Hilda didn’t have anything else to keep her busy, she would constantly look to her left to glance at the big bulge in her girlfriend’s pants. She was a straight man just a few moments ago but now she was starting to get hungry for a big veiny cock, making her own puny cock twitch inside her tight pants.
The former man would surprise herself as she got more horny. She looked down in shock to see that her puny penis wasn’t the only thing becoming erect from arousal, her already giant tits would grow even further! They were threatening to burst her clothes. She sighed as she had forgotten that she had also written about wanting her girl’s tits to temporarily grow bigger when she was horny, kinda like a womanly erection of some sorts, and now she had to put up with exactly that.
Camilla would struggle a bit to focus on her task. The blonde woman saw Hilda struggling with her expanding boobs. Her flushed face, moans of pleasure and her attempt to hold them in to avoid further embarrassing herself was super hot in her eyes. Her dormant dick lightly throbbed as it threaten to become erect, trying to calm down as best as she could before naughty thoughts clouded her mind.
“Focus focus focus” she said. Thoughts crossed her mind, thoughts of using her massive penis and destroy her submissive girlfriend’s pussy, wanting to make her feel good, wanting her to worship her lengthy member and fill up her holes with warm sticky cum.
Camilla wouldn’t resist much longer, finding a parking spot as soon as possible. “C’mere babe~ I know you want this!~”. The young woman unbuckled her seatbelt and pulled down her pants and underwear, revealing her big testis full of cum and her flaccid dick about to become hard as she looked at her squealing girlfriend.
“W-Wha-! R-Right now?! But people might see us?!”. Despite her words sounding hesitant, Hilda couldn’t take her eyes off of her babe’s cock as blood pumped into it, soon becoming fully erect. “It’s not a question, girl~”. Camilla would go in for a kiss as she unbuckled Hilda’s seatbelt.
The pink-haired girl would moan in between smooches, her lover switching between groping her massive tits and stimulating her tight wet pussy and pathetic dick. The two would eventually move towards the seats at the back, where Camilla would place her sweetheart on all fours as she slowly but surely inserted her massive dick inside Hilda.
Hilda screamed and moaned in pleasure as she felt her insides rearrange due to the sheer size of her girl’s monster cock. Camilla would grunt and let out a few moans of her own as her lover’s vagina was insanely tight, feeling like it was hugging her twitching cock tightly, occasionally contracting to feel even tighter.
Hilda was supposed to be Henry, the man rearranging Camilla’s insides, now the roles have swapped due to a mistake, but this may just be the best mistake of their lives. The dominant woman would start thrusting her member in and out of Hilda’s tight slutty hole, starting slow and steady but quickly picking up the pace, her libido raising as she heard her girlfriend scream and moan for more.
The former male’s mind and body was being destroyed by her girlfriend’s big dick, she loved every second of it, she loved every second of being used as Camilla’s cock sleeve, and soon, she hoped, as her cum dump.
The big dick woman continued to pound her girlfriend’s vagina. As Hilda had written for Camilla, her pussy was still very tight even after an hour of getting fucked by the human equivalent of a horse cock, making the sexual experience beyond orgasmic for both of them, mainly for the Camilla though. Hilda had forgotten about her rule of not cumming until she was allowed to do so by her partner, said partner only allowing her to do so whenever she herself came.
The car was full of the odor of sweat, cum and pussy juice as the couple just kept on fucking and fucking. It was like a never ending cycle of lust, one addicted to cock and semen and the other possessing incredible stamina and loved using her massive appendage. Hours would go by as the two fucked in every way possible, vaginal, anal, oral, Hilda and Camilla worshiping each other’s perfect bodies until they finally showed some semblance of being tired. They fell asleep in their car, in the huge puddle of their own fluids. They weren’t aware yet that this was the beginning of their new lustful lives.
