They leave most of their belongings, including their clothes, and run buck naked behind the house. They set up a big blanket and place some sex toys in a basket. Margaret makes sure to get all the sand off the blanket so it doesn't interrupt their fun as Jane is opening a brand new bottle of massage oil.
Both sit on the blanket smearing the oil all over their naked bodies making their bodies slippery and shiny. Margaret has her phone nearby just in case but far enough so it doesn't get in a way of their fun.
"Let's play a little game." Margaret says lubricating her genital region. "If you cum first you have to make me a really fancy dinner."
"And if I win?" Jane answers massaging the oil into her generous tits with pleasant squishy noises.
"I'll let you in on a biiiiig secret." Margaret looks towards her phone.
"Doesn't seem like a fair bet."
"Trust me, it's a really good secret."
"Deal."
Jane pulls a pink double sided vibrator from their basket. It's thin, flexible shaft bends easily around into a "U" shape. She gently inserts the tip into Margaret's slippery depths giving it gentle push in and out with the rhythm of her lover's breath. Once the dildo is sufficiently lubricated with Margaret's fluids she flips a switch and bends it upward to spear herself on it, then lays on top of Margaret once again bending it into "U" shape connecting them as tiny vibrations start.
"It's something new I found for both of us. The vibrations will start slowly and keep increasing until it reaches max, then it will stay there until we turn it off."
Margaret already blushes as the vibrations enter noticeable setting. "Got a nice kick to it, I'll give you that." she says tensing slightly. "But not enough to make me cum."
"No, of course not. But this on the other hand...." Jane lays flat on top of Margaret, grabs one of her slippery breasts and runs her tongue around large brown nipple.
Margaret moans. "You cheater...." she says sensually arching her back.
"I can't be a cheater if you didn't setup any rules... mommy." Jane grins knowing how calling her that turns her on.
"S-stop that. I can't... oh god.." Margaret is getting closer as Jane sucks hard on the nipple coaxing drops of thick liquid out and into her mouth.
Jane is still nowhere near there as the vibrations reach the middle setting. She is getting a steady stream of creamy milk out as her hand milks the other slippery tit gently, but firmly, like an udder. The unattended drops streak onto the blanket.
Jane impatiently pulls the vibrator out of her pussy and puts it with the other one inside Margaret, then proceeds to suck more milk swallowing the tasty liquid like her life depends on it.
Margaret screams as the combined vibrations and stimulation from the forced breastfeeding brings her to the absolute edge of toe-curling orgasm. She tenses all her muscles trying to stop herself, but it only delays the inevitable by a few seconds.
She cums, her tits spray dense milky substance out like bottles of cream giving Jane a nice mouthful after mouthful until even she can't keep up any more and has to stop letting the liquid drip and congregate on the blanket around Margaret's quivering form. Margaret squirts hot pussy juice out in a flash of blinding light clouding her thoughts. She rides out the orgasm for a minute until she's brought back to reality by slippery sounds of her girlfriend masturbating to her messy state.
Gasping for air Margaret collects herself and sits upright taking the toy out. Looking at her oily body and dripping breast she collects a handful of the thick liquid and drinks it out of curiosity. It tastes sweet and creamy, not unlike a coffee creamer, but the consistency is so dense... almost like cum.
Jane is still trying to reach her own orgasm."Please let me tell you something now." Hesitantly Jane takes fingers out of her snatch with empty unfulfilled horny feeling, curious to hear what Margaret wants to say.
"Ok, so here's the secret."
Margaret tells her all about the phone. All the changes she made and all that happened since then. Jane believes her which even Margaret finds surprising.
"Oh yea. These apps exist. I've heard about them. Really hard to get them since you can really mess up reality. Like what you did to the children we apparently had, but if they are okay then no harm done."
"Maybe we can bring them back after vacation. This is some really powerful stuff we're dealing with but if we're just a bit careful there shouldn't be any problems."
"Think about all the different changes we could do, anything is possible. You could turn both of us into some girl's ovaries. Give me some animal junk. Turn into a big pussy and let me crawl inside like a sleeping bag. Even transfer kids to me and make me your personal breeder."
"If you want that to happen it could be arranged."
"No. I'm just saying. Anything could be done, any perverted reality or dream you had can be fulfilled. This is pretty amazing but scary at the same time since all the changes will be permanent unless it's all changed."
"So we stop using it and maybe..."
"Nonsense. Just tick the box to let both of us be aware of changes and lets have some fun!"
Margaret did this and handed the phone to Jane. "Since I already changed so much it's only fair for you to get a chance."
"Fuck yeah! I'm giving myself something weird and kinky, this is gonna be amazing." Jane, still super horny, is idly rubbing her clit with one hand from excitement.
With that she points the phone at her spread oozing crotch and taps some buttons.
"Oh you can just point it at stuff? I thought it just picks subjects randomly by proximity." said Margaret.
"Yeah you point it at person, thing, or body part. Look!" With that Margaret glanced at the newly generated sentence.
"Jane is close to orgasm and will squirt from her lubricated pussy."
