The author of the omnipotent cunt deserves all credit with inspiring my MtF version. I'm just going to slightly one up them by also doing it with breasts and cock.
Mary bent down to look through the peephole and saw her friend with benefits/ fuck-buddy Gabriel. Mary had a hard time and low self esteem (until now), so she couldn't get a boyfriend despite being reletively attractive, so she turned to online dating apps, she had more problems with the dates always going wrong, until she met Gabe, at that point she was desperate and just wanted to fuck. Gabriel was kind enough to take it slow and Mary eventually felt he was to good for her, but didn't want to lose him, so she proposed they become friends with benefits/fuck buddies/fuck friends, either way friends who occasionally have sex.
Mary had forgotten that today they had scheduled to have sex with each other. But now that he is here, she plans on making him her personal fuck toy of a wife. Mary opened the door and invited Gabriel in. The moment Gabriel stepped in, she slammed to door lock behind him and grapped him. Gabriel in shock, could only ask "Mary is that you?"
Mary replied yes to him while dragging him. They quickly entered her bed room in which she threw him onto the bed and tied his hands to the posts. Mary could see the fear in Gabriel's eyes and decided to reasure him. She loves him and doesn't want to hurt him, but her raging boner is compelling her to fuck hard.
"Gabriel don't fear, I won't hurt you." She then went downstairs to grab the box of vials. Returning to her room she continued, "This box of vials here is what turned me into the person infront of you. I drank some and now you will too. I want to try out my new meaty cock, but your body won't be able to handle it like you are now, so I will use the vials to turn you. Think of it as a new sex position we are going to be trying out for our fuck day."
Gabriel face changed from fear, to apprehension, to a bit of lust as he heard want she said.
Mary already having an idea of what to do grabbed a bottle named woman+. She then helped Gabriel drink it down after convincing him some more. Gabriel's body barely changed into a woman's. He was definantly a she now, her cock was gone replaced by a small pussy, her chest now had A-cups on it and her face was feminine now, but that was it.
Mary was a bit disapointed, but she guessed it was very difficult to turn a man into sexy woman in one vial.
Mary grabbed a collection of vials she planned on using.
She grabbed: Pussy+, Breast+, Ass+, Woman+, Curvy+, Muscles+, Tongue+, Magic+, Power+, Liquid+ and Height+
With these vials Mary began to work. Gabriel having no strength to resist Mary in any way, let Mary do as she pleased to him/ now her.
Mary target Gabriel's overall figure forcing the new woman to drink a coctail of vials.
Gabriel moaned as her body changed, she grew to 7', her body gained an hourglass figure as her hips and ass expanded, her breast grew till they where the same as Mary's head sized tits, her thighs thickened and her hair expanded going till, if she was standing would reach her large ass. Gabriel looked like Mary exept for hair color, muscles and height.
Now with Gabriel being similar to her Mary then targeted her pussy, wanting to turn Gabriel's cunt into the perfect pussy to take her massive cock. Mary using her thick muscular finger began working Gabriel's twat, till it was wet and loosened a bit. Mary the shoved a funnel into Gabriel's cunt before dumping the coctail of fluids she made with the vials.
Mary used 2 Pussy+'s, 2Muscle+'s, 1 Magic+, 1 Power+, 2 Liquid+'s , and 3 Tongue+'s on Gabriel's pussy.
Gabriel's pussy, womb and ovaries where coated with the fluids, she felt the changes happen immediately. Gabriel felt her pussy bulge out, now no longer being able to be hidden in any underwear let alone pants, Her stomach bulged a bit and gained a 4 pack. Gabriel reached down with her hands to play with her changing pussy. Her pussy began drooling out juices. Her mind began to connect to the new muscles she had control over in her needy drooling cunt, and her cum hungry, muscular womb. Gabriel felt as three prehensile tentacle like tongues wrapped around her finger, completely under her control. Her pussy then became pulsating an electric current, increasing the pleasure she felt. Her pussy now generating the power of a nuclear reactor, all for sex, forever greater pleasure.
The last changes Gabriel felt numbed her mind a bit, only because of the overwhelming pleasure she felt. She felt the moment she has a very good fucking her mind would return to normal, for now it completely succumbed to a haze of lust, pleasure, and desire. Her pussy changed gaining hypnotic abilities that could easily mould the mind of any lovers, bestowed by the Magic+ vial as well as her pussy-juices getting laced with cock enhancing hormones and aphrodisiacs. As if to futher complete her insatiable sex goddess pussy, her cunt began leaking out a pink mist of pheromones. Her pussy, while her mind was lost to lust gained a some level of sentience.
Gabriel squeezed her pussy down hard and orgasmed from the pressure, squirting pussy-juice all over Mary's legs creating a puddle.
Mary smiled as she saw Gabriel succumb to her new pussy. Said new pussy opened up wide to reveal swirling hypnotic color, which hypnotized Mary, if only to continue what she had planned on doing and encouraged her to see Gabriel as her wife and equal. Gabriel's pussy's sentience was just an extension of Gabriel's inner will and desires. The pussy then made sure that Mary would gain cock equal for a pussy this powerful.
Mary went on to Gabriel's tits. She used needles to deliver the liquids, since she was targeting the nipples and the breasts. She used: Pussy+ one for each nipple, Breast+ 2 for each tit, Msucles+ 2 for each tit and nipple, Liquid+ 3 for each tit, Tongue+ 3 for each nipple, Magic+ 1 for each tit and nipple, and Power+ 1 for each nipple and tit.
Gabriel already lost to lust felt the changes in her tits. Her breasts grew to take up the space of her chest, becoming hyper tits. Her nipples on the outside didn't alter at all, only on the inside did they change. Gabriel's nipples opened and closed up as they grew muscles, her nipples on the inside becoming just like her pussy. Her tits grew a bit more as they swelled with milk, they reached down to her waist in a sexy teardrop shape. Her tits gainning muscles on their own helped to relieve the crushing weight of themselves on her. Three tentacle like tongues came out of her nipples in a fountain of milk.
Like her pussy Gabriel's tits began generating the power of a nuclear reactor, making her tits hot with pleasure. Her breasts then became truly gravity defying as the Magic+ kicked in. Her milk gained aphrodisiac properties and hypnotic suggestion properties. The milk also became laced with hormone enhancing properties. Her Breasts gained the same level of sentience as her pussy, having control over what the hormone enhancing abilities of the milk
Mary saw Gabriel's large pillowy tits and just wanted to lie on them while fucking her, but held back as she wasn't finished yet. Mary unsure if Gabriel could stand let alone breath with such massive tits on her chest decided to give Gabriel a small bit of a Muscle+. Gabriel gained just a hint of muscles in some places, helping out her already sex goddess figure.
Mary targeted Gabriel's mouth next with a Pussy+, 2 Tongue+'s, 1 Power+ and 2 Muscle+'s. Gabriel felt the back of her throat change into a pussy, her tongue lengthened and her whole throat became a perfect cocksleeve. Gabriel could now easily deep throught Mary all day.
Mary then target herself, seeing Gabriel's massive hungry pussy, made her already impressive cock feel a bit inadequate. Mary took a Cock+, then injected a Muscle+, Power+, and Magic+ into her cock.
Mary felt her cock grow till it was 2 foot long. He vains grew larger as her cock twitch with power, pulsating a pleasurable electric current sure to drive any woman she fucks wild with pleasure. Mary felt the muslces in her cock change from just allowing it to get hard to becoming fully tentacle like. She felt the level of control of her poweful cock and new she could use it the grab hold of things like her hand. Laslty her magnificent cock gained sentience, subserviant to Gabriel's pussy and pussy enhancing cum.
Mary couldn't wait to fuck Gabriel any longer, she was a bit jealous, because during the entire time since she changed Gabriel's pussy, Gabriel's been cumming non-stop, slightly flooding her room with love-juices. She was madly in love with/hypnotized by Gabriel and wanted nothing more to take her as her wife
