A scene opens up with Atomsk waiting for TME to show.

TME than walked in while he had some pieces of paper and stuff in his hand like a list of ideas while he looks thoughtful… so much so he walked into a pillar making him stop to rub his nose while he grumbles about remodeling.

Atomsk blinks a bit.

"Hey man, all okay?"

"Hmmm… oh yeah, sorry was just thinking of some ideas that this story can go… got a few… one is an all female Ooo or thats what it seems at least… leads to one idea of mine so we can use Emerald and maybe Cedric later under their female names like Esmeralda and Cedrina but that's for much later… but this story is mainly a Fionna centered story so should have her as the lead and stuff, question, want her to be a Futa human or no?" TME asked while he moved to get next to Atomsk while TME looks thoughtful on ideas.

Atomsk was thoughtful.

"Depends, is she born with one or uses a spell to summon it?"

"Hmmm… born with it but can store it with a spell later, mainly think of the version of Surge we use who is normally a futa and has to store her cock via magic and stuff… Fionna may not even store it in this story unless a REALLY rare male is met, again a mainly centered female or futa story so would impact on what OC's we can use or their genderbent variants at least."

Atomsk was thoughtful again.

"Hmmm… go Futa. Feels like a Vanilla in Heat eh?" He said.

"Hehe, yeah, anyway I'm going to try and have low OC use unless its Canon characters with OC names, like Bandit princess as Jasmine or Jungle Princess as Elena, point is should be mostly canon until later, give people what they want more or less instead of using OC's to throw them off… may as well give warning that things will happen with OC's later, but not now, and if we use Canon character with OC names… well unless said in Canon, can't just call Jungle Princess JP or Phoebe FP since Phoebe is FP's real name but no name for JP… point is expect names for the princesses who have no names at least… for now ready to start officially with Fionna and Cake at the Treefort?... If we're going females mainly, may as well have Cake instead of Jake and stuff." TME said while he shrugs his shoulders.

"Makes sense so let's go nuts." Atomsk said.

"Nice… anyway as you read people, pure futa Fionna on females mainly with a VERY rare male moment… will save the male stuff for MUCH later, can make it even a good event on males being a rare thing… but for now… onto the story!" TME said as the scene shifts to…


Ooo/ Treefort/ Fionna, Cake

The scene currently showed the camera circling around the treefort as a narrator explained some things… come on think of it as some crunched up backstory people to prevent a long winded explanation later down the story.

"Greeting dear readers… what you are reading is a more or less a special dimension… one that is rather unique in it being a rare combination… there could be others like this in other stories, other dimensions, even in other media if people want to get creative… point is this story more or less embodies how chaotic the Adventure time Multiverse is with this Dimension being a Rare combination of there being mainly female power centered room, males being even rarer, and even the main heroine of this story being female… on some level… as you may know… this Fionna is more or less dual gendered… which will make things VERY interesting for her when her 18th birthday happens… which is ironically today… so enjoy the lustful hijinx everyone and remember, this story is mainly for fun, hopefully not much conflict will happen unless Fionna runs into a female enemy… hehe… thats when things get spicy…" The Narrators voice said as the camera flew into a particular window of the treefort and showed that the day was just getting into the room as an alarm went off… one that was rather festive themed as groaning was heard on the bed.

"Damn alarm." Said someone with feminine voice as they brought out their arm to stop the alarm.

The arm though tough looking with toned muscles and with flawless skin hits the alarm and once the sounds were ended, the figure yawns and she sat up in some kind of sleeping bag with only one arm and a female face was seen and she yawns again as she rubs her eyes of sand.

"Another day, another adventure." She said as she gets up to go to the bathroom.

As she got out of her sleeping back, all the female had on was a light blue T-shirt and panties… she had a shapely figure, and a MASSIVE bulge barely hidden by the panties, honestly if the female, Fionna as you all know, was a full female, would be a supermodel right now… with both genders… looks like she was the apex of both worlds by having the best of where it counts… all in all, thanks to today being her 18th birthday, seems she would be getting an interesting guest because after Fionna entered her bathroom… an amused giggle was heard as Marceline the Vampire Queen appeared from the ceiling when she turned Visible and had a smirk on her face.

'Just in time.' Marceline thought as she got a good gift for Fionna.

Comically enough, Marceline's hair behind her back starts to lengthen oddly enough but this turned out to be more of Marceline appearing and in a large ball of hair was a Slumbering Cake who missed the alarm thanks to Marceline blocking the sound from hitting her, and Marceline looks really amused when she had Cake in the living room and looks to see BMO and smirks at them.

"Hehe… make sure that they don't wake for a bit… going to give Fi a birthday gift to remember hehe." Marceline said when she smirks at the robotic game companion friend.

"Sure thing nice Vampire Lady." BMO said with a smile.

Marceline smiles as she pets BMO on their head and floats up to Fionna's room and smirks when she starts undressing to show her nude body… she wouldn't let it be seen yet because she turned invisible and dropped clothing on the ground as she floats to the bathroom and used her shapeshifting to slip under the door to see what Fionna was doing and smirks when she saw Fionna in the shower and Marceline got a good look at her figure and more.

Fionna has got a athletic build for one her age with long blonde hair. She also got a nice hourglass figure with curves, along with some scars. Her breasts were C-D size as her ass was well tone.

Marceline licks her lips when she saw that and practically drools when Fionna turned to show that Fionna had a massive cock with a morning wood issue with large heavyset balls… she had a tight looking virgin pussy and ass and pretty much left the morning wood alone most likely from habit if Cake never taught them anything on masturbation… now this could either be a natural thing or mutation but Fionna had a massive 10 to 12 inch cock that was 3 in width… definitly well above the average and had thick veins all over the cock as well showing how intense the cock was.

'Hehe… Happy Birthday… to me.' Marceline thought as she can't wait to get started.

As she waits for Fionna to wash her hair and body off, even watched as Fionna cleaned her cock under the dickhead and more showing she took cleanliness to a good level… once Fionna washed her hands… she jolts when she felt some kind of pressure on her cock like a hand was on it and she didn't know what was going on when she felt this and… groans when she felt the pressure move on her cock while she looks royally confused and felt really weak right now.

"W-What the fuck." Fionna said before groaning as she didn't know what's happening.

Marceline on her end smirks as she used her other hand to stroke Fionna's cock while licking her lips while she looks amused at the confused look on Fionna's face and chuckles when she speaks.

"My my my… didn't know my minion had a hidden meat sword." Marceline said when she smirks as she made herself visible to Fionna while Marceline was on her knees in the shower surprising Fionna immensely.

"M-Marceline?!… what are you doing?" Fionna said.

"Hehe, well Fi… was going to surprise you in your room when you woke on your 18th birthday but when I saw how tired you look getting in the shower, figured I should wait to see what happens… and must say you really should have shown this cock here… would have made any attempts at dating me MUCH higher… granted couldn't do anything until now but since your 18… may as well give a gift that will really help you hehe… losing your V-Cards." Marceline said though Fionna blushing did look confused.

"V-Cards?... uh… I don't have Cards with V's on them." Fionna said making Marceline sweatdrop as she sighs.

"OK look Fionna, first off V-Cards are first times in tier 15 that happen that can only happen once, once you have sex, you're no longer a virgin, and before you get alarmed, no you can have more sex, its just the first time will be the most special to you more or less unless you don't care much on that… mainly… I'm willing to help make you a woman… Bonnie and I figured since you have more gold than most and can get what you want for your birthday at anytime, figured we should help you with learning tiers if Cake never did teach you… and since you didn't get what a V-Card was… pretty sure you'll need this… big time since I heard many other Princesses will come here for this meaty cock of yours… want to know how to survive a pussy and more?... well better agree to let me teach you right… no mind games… no jokes… straight up offering to have sex with you in a lot of ways and Bonnie will be coming to test you as well… unless you have no freaking interest even with me being on my knees here." Marceline said while she gave Fionna a half lidded look at the end.

Fionna jolts at the look.

"I… do want to learn. Please teach me, Marcy."

Marceline now smirks at this.

"Nice… just a heads up… while I will be going easy on you for now… know that some princesses are MUCH more kinky than others… kinky means that in tier 15 they would do things that get them off in a particular way… as long as you agree to humor some things and suggestions from me since again… many princesses will be coming for this huge cock of yours… well… I don't mind teaching you everything I know… could be a good Mistress and Minion bonding moment… who knows… get lucky enough and Bonnie and I may have you as a surrogate in knocking Bonnie up… being undead on my end does cause me to not have the ability to have kids… well… to Bonnie when she scanned my DNA, is so low may as well be impotent… can explain more with her later… for now… ready to enjoy your 18th birthday and really become a woman?" Marceline said with her licking her lips as she strokes Fionna's cock again.

Fionna blushes brightly.

"Y-Yes." She said.

"Good… just a heads up… if you feel a sick feeling in your stomach like some kind of pressure is building there or you feel like you're about to wiz or something while I do this… don't worry… you did use the bathroom before showering which I'll assume… so I'll explain here that these packed balls here will be getting some sweet relief for unloading sperm for the first time in their life hehe." Marceline said when she fondles Fionna's balls as an example.

Fionna shudders at that action.

"O-Okay." She said.

"Good… now… considering you have no idea on Tier 15… let me show you a trick that will make you want to visit me a lot." Marceline said when she opened her mouth wide and slowly starts taking Fionna's cock deep in her mouth, not gagging at all from the size and with no need to breath, a large bulge formed in Marceline's mouth and Fionna was stunned from pleasure hitting her head when she felt her cock getting fully deepthroated… though she did gasps when she felt something blast from her cock and Marceline was amused when her stomach slowly swells when Fionna was having her first ever climax in no time… guess a sudden deepthroating like this would overwealm a virgin like her which amused Marceline as she fondles the throbbing balls in her hand and even rubs Fionna's folds to help her more.

"F-Fuck… Marcy!" Fionna groans as her toes curled on the shower floor.

Marceline mentally smirks more as she waits for Fionna to tap off, when she did she slowly pulls her head back and off the cock and looks amused when Fionna was rock hard, hell she looks harder than ever while Marceline pats her stomach which looked bloated.

"Fuck… guess I went too fast and got you some relief before you could enjoy a good cock sucking… how do you feel though?... balls feel much lighter?" Marceline said with a teasing look on her face.

Fionna blushes.

"Y-Yeah."

"Good… let me try again and this time much more… built in… since you have heavy looking balls right now… bet it will take more than one suck to finish this cock so…" Marceline said when she moved to suck Fionna's cock again… this time takinging only half in and bobs her head while she sucked Fionna's cock properly, this time being more aware of Fionna and her stamina being lacking given her virgin state.

"Oh fuck." Fionna groans as she felt Marceline's mouth on her cock again.

Marceline mentally giggles while she keeps on with her sucking actions… funnily enough seems Marceline was not the only one with invisibility abilities because some kind of floating drone was floating outside of the window to look at the duo and on the other end was Bubblegum… but surprisingly instead of her lab, she was in a large bedroom with a number of princesses and other women in the nude in the bedroom… all 18 or older, and all seeing how girthy Fionna was…

"Wow… Fionna is definitely big down there." Said one Princess who was blushing.

"Indeed… anyway the reason I called you all here was mainly to help set up a truce because lets face it… many of you before I called you were all about to rush to Fionna and try and get her on your side romantically… or in some cases just have fun or… try and give second chances… but honestly many of us would fight for Fionna if thats the case on various grounds so I called you all here before you could cause issues so we can talk civil in a number of matters…" Bubblegum said while she glanced at some in particular like Phoebe the Flame Queen and Huntress Wizard in the room while those like Susan, Frieda, Canyon, and many more were here.

"How can we be civil since we all want the same thing." Breakfast Princess said.

"Well there are three methods… a combo with similar results is one I do not recommend and that is cloning… same with robotic doubles since that may as well make Fionna Minerva, in capable of birthing kids or giving us kids… option two… we make a contest to see who can get Fionna's heart more or less… with conditions for certain people like Phoebe here so I can work on a way to make Fionna fireproof so they don't burn around her… finally… depending on how things go… we share Fionna more or less, ergo, make a harem for Fionna more or less… should be the simplest method and helps them with their stamina… as you can see I sent Marceline to train them and get their virginities… ALL of them… so don't expect Fionna to have an innocent look in her eyes like she does for now… before you all ask, unless Fionna gets lucky and by that I mean full moon shooting star and the moon is a different color lucky, Marceline is impossible to impregnate… who better to train for sex than her?" Bubblegum said when she had a hand on her hip.

The females in the room would speak but didn't… since no one knows sex better than Marceline.

Bubblegum nods her head.

"OK… so if you're OK with sharing or very least working to try and seduce Fionna… lets go over some ground rules before we start our own fun… we are nude after all… may as well enjoy the show." Bubblegum said when she reminds many they were nude here.

The females either blush or didn't mind the nakedness like Huntress and Canyon as everyone else looks at the screen.

When they did, they saw Fionna moaning with a pleased look on her face as she came hard inside of Marceline's mouth making her cheeks puff with sperm when Fionna was a virile as her last load much to Marceline's pleasure.

Marceline hums for a bit before she starts drinking down Fionna's load.

After Fionna rides out her orgasm, Marceline used her hair to catch Fionna before she could fall.

"Hehe, careful Fi… don't want to pass out yet… got the real virgin busting to do and believe me… if you thought blowbjobs are good… well you have no idea on what real tier 15 is… if you want to know, this maybe tier 13 or 14 on the tier 15 list… the foreplay before the final tier hehe." Marceline said with a smirk on her face as she turned off the water to the shower and worked to dry Fionna off with a spell much to Fionna's surprise on the spell use.

"Y-You knew a spell to dry off?" Fionna said.

"And a few more… mainly what some call as safe spells… spells that won't fuck with your head… may not like magic after what happened to Ashley but can admit that spells for this will be handy… Bonnie may not like magic but quick drying and cock hiding are fun spells to use… anyway ready to head to your bed?" Marceline asked while she smirks at Fionna eagerly.

Fionna is cautious.

"What about Cake?" She said.

"Hehe, well if she is still sleeping, she sleeps… if not… well leave the talking to me… could have her join in on the fun… she may have had kids with Lady Monochromicorn and this Lady Rainicorn woman… but seems they don't mind if Cake has fun from her home… bit of a tip in case you worry on things…" Marceline said when she picked up Fionna bridal style and carried her from the bathroom.

Fionna blushes brightly after hearing this but blushes from being carried which made her heart beat a bit.

Marceline smirks at this.

"Hehe, relax Fi, can hear your heart beating… think of it as practice for the wedding if you marry someone… pretty sure with a cock like this you could get any lady in your bedroom." Marceline said with a teasing smirk on her face while the Drone entered the building when it used a special ray to make the window phasable and it followed Fionna and Marceline into the bedroom and many princesses saw Fionna looking adorable as Marceline brought her to the bedroom and sets Fionna on the bed.

The females did blush when they saw that despite her toughness, Fionna was sinfully adorable with the blush… and cock.

Marceline on her end smirks when she grins at Fionna.

"Hehe… want to see a trick since some ladies and princesses could do what I do?" Marceline said when she moved back from Fionna and when Fionna looks… Fionna and many Royals watching blushes immensely when she saw Marceline form a cock that was definitely 12 inches long and 3 in width, similar to Fionna's cocksize but a bit bigger showing it was around the later inches, not the earlier sizes.

"Y-You can also grow your own?" Fionna said as she didn't expect that.

"Hehe, shapeshifter remember?... think Bonnie and I can't form cocks?... granted Bonnie has to mold one and her body does the rest to make it work but I fully work to make the cock here… can even make it various species as well." Marceline said when she reformed her cock to look like a horse cock, a canine cock, and a ridgged Dragon cock with the kink factor rising with some small tentacles on the cock and finished with a cat cock with barbs, the cocks looking a mix of grey and purple with a gray shaft and dark purple dickhead on some of them.

Fionna and the other females were surprised at the info.

"Wow… had no idea." Fionna said.

"Hehe, well now you know… guess who gets your pussy virginity today before others?" Marceline said with a fanged grin when she looks eagerly at Fionna lustfully.

This made Fionna blush again while her cock, surprisingly throbs like it was excited.

Marceline smirks as she moved to get over Fionna.

"Before I do take your V-Cards… want me to keep the cock on my body while I have my pussy take your dick's virginity or want me to lose it?" Marceline asked while she had a hand on her hip as she stood over Fionna with a throbbing cock over Fionna's face.

Fionna lightly gulps.

"Y-You can… keep it on you."

Marceline smirks as she moved to use a hair hand to aim Fionna's cock at Marceline's folds.

"So… ready to become a real woman Fi?" Marceline teased when she rubs the head of Fionna's cock at Marceline's pussy lips.

Fionna shudders at the feeling before nodding her head.

Marceline than moved to lower her body and she groans when she took in Fionna's cock deep in her folds while Fionna on her end grits her teeth when she could feel how tight the Vampire Queen was.

"F-Fuck… so tight." Fionna groans.

"Hehe… well welcome to womanhood Fi… try and not burst yet… I want my load in you to build up." Marceline said when she licks her lips and moved to fondle Fionna's breasts and Marceline moans when she starts riding Fionna's cock making slap sounds being heard as many royals watch Marceline's ass bounce when she rides Fionna's cock taking it deep in her folds again and again.

Fionna grunts and groans as she couldn't believe she lost one of her V-Cards as she grabs the sheets of her bed.

As Marceline groans and moans more… she grins when she looks down at Fionna.

"Hows my pussy Fi… want to bust a nut inside of me?... want to try and take a risk and knock me up?" Marceline teased surprising many royals watching.

Fionna groans.

"A—Ah!… It feels… so good!" She moans.

"Hehe… thats right… enjoy it Fi… once you bust a nut… I'll be busting that pussy and ass virginity wide open…" Marceline growls while she rides Fionna harder and as her eyes glow… Phoebe blushed when she saw how intense Marceline was right now.

"W-Wow… Marceline is getting a bit intense." Phoebe said.

"Yes well when Marceline gets worked up, she really gets worked up… honestly reason why I love Marceline, but lets just say even I have trouble keeping up with her." Bubblegum said with a smirk on her face as she worked to mold a cock when she sat on the bed before many Royals.

The females saw and blush when looking at how big Bubblegum's cock was.

It was about as big as Marceline's cock and she smirks at the others.

"What?, I know most of you like to form a cock from your bodies… especially you Phoebe since you did talk about how cute some women here were." Bubblegum said when she smirks at many… mainly Phoebe to tease her.

Phoebe did blush after hearing that while ladies like Huntress Wizard, Canyon and Elena, the Jungle Princess, were amused.

Bubblegum looks amused when she looks at the others.

"So… anyone eager to start their own fun, please don't let me stop you, may as well enjoy ourselves." Bubblegum said when she wondered which princess would come to her.

Few ladies were shy before Huntress spoke up.

"I'll take a whack at it."

Bubblegum smirks at this.

"Hehe, figures… never did anything with you… eager to try and get that kiss from me or more since that wizard competition?" Bubblegum said with a smirk on her face while she stroked her cock.

Huntress smirks back.

"You betcha." She said as she approaches the Candy Monarch with swaying hips.

Bubblegum smirks while some were confused… though before many could ask, Bubblegum moved to a communicator and spoke into it.

"Minerva… mind if some of you and your bots waiting come in and… help encourage people to relax?" Bubblegum asked while she waits for Huntress to get close as she lets go of her cock.

Most blink when they heard that before the doors open and comes in Minerva Campbell, Fionna's mother, and her hand select bots.

"Certainly Bonnibel. Glad to be a part of this." Minerva said.

"Wait… Fionna's mom is apart of this!?" Phoebe said with a surprised look on her face as Minerva giggles.

"Well of course, need to make sure… prospective ladies for Fionna are not going to have issues and may as well get some samples to collect to see who has a better compatibility childbirthing wise with my daughter… I mean… unless you don't want to know who can be a good surrogate at least or find out if your compatible… you are free to leave but…" Minerva said as she and her bots smirk when they start undressing.

"Considering how pervy you all are in watching my daughter fuck the Vampire Queen… pretty sure you all already made the choice to stick around… may not be flesh and blood and wasn't in as good a shape as Fionna… but many did say I looked good for my age so even if she isn't immortal… pretty sure she will have a good figure years from now." Minerva said when she and her bots undressed showing well mature looking figures… some looks various in sizes but seems the main Minerva had the most Fionna like look of them all.

"Before any ask, this bot speaking is my default… the others here have their figures altered for tastes… so… think it would be bad to leave when me and my bots can help all of you eager royals feel good?" Minerva said when she and her bot squad gave the female Royals eager looks.

The female royals all blush and despite the look alikes, Minerva was indeed attractive.

Minerva smirks as she looks at the bots.

"Split up ladies, lets get a long overdue lay and make sure that Fionna won't have any issues when these horny sluts go for our daughter." Minerva said when she and her bots smirk when they look at the Royals with eager looks when they approached a few Royals while the main Minerva approached Phoebe of all people funnily enough.

The bots chuckled before each one went to a blushing royal.

As Minerva got before Phoebe… she took Phoebe's chin in her hand.

"So… an eager unstable fireball like you wants to try and get back with my daughter again?... or very least use her as a fiery cumdump?... well two questions… one… are you stable or did you find a way to circumvent that unstableness?... and two… why go for Fionna again when I heard you broke up with her?" Minerva asked when she looks amused when she looks at Phoebe's body to drink in her figure.

Phoebe blushes a bit.

"Well… after being friends again for so long… I start to miss what we had before the breakup."

"Hmmm… maybe… still doesn't explain the unstableness…" Minerva said as another Minerva bot smirks.

"Well from medical checkups with some flame women… seems one in particular Blaze, Phoebe's personal Advisor has an… interesting way of making that unstableness go from a supernova to an explosion from a particular point of her body." Another Minerva said near Elena the Jungle Princess… this Minerva was more top heavy that the others and Elena was enjoying herself when she fondles the breasts and sucks the nipples before her.

"Is that right?" Minerva said with a smirk making Phoebe blush again.

"Hehe, yeah… have Phoebe form a cock and when she is about to climax… kiss her… we should see what gets Blaze's attention with the Queen here." The Big breasted Minerva said when she pets Elena's head.

Phoebe blushes more before she shyly summons her own cock that was at least 10 ½ inches long and 3 in width.

Minerva with Phoebe smirks.

"Oh?... and you wanted to use something like this on my little girl?... for shame… you should use bigger since it seems Fionna will be a Size Queen soon…" Minerva teased when she trailed a finger on Phoebe's cock to mess with her.

Phoebe shudders at the touch.

"M-Maybe I don't want to… h-hurt her." She said.

Minerva smirks.

"Oh she is a tough one… take a look…" Minerva said when she had Phoebe look and watched as it seems Fionna, not wanting to be on the receiving end, moved to have Marceline on her back and was in a missionary position with her, kissing Marceline while she rammed her cock deep in Marceline's folds, seems a moment happened with Marceline talking Fionna into taking the lead and she was aggressive it seems as she dominates the Vampire Queen as her balls slapped against Marceline's ass cheeks..

Marceline was muffly moaning and groaning as she enjoys this moment before wrapping her arms and legs around Fionna while having her tongue fight hers.

As this happened. Minerva smirks when she looks at Phoebe.

"So… think she would be weak offensively?... just wait till Marceline gets her vaginal and anal virginity and train her more… just think of the pounding she could take with a cock like this… and if Bubblegum makes Fionna fire resistant at least, could be one hell of a fiery passion filled time between you two." Minerva said when she gripped and stroked Phoebe's cock and in time with Phoebe's thrusts like it was Fionna riding Phoebe's cock right now.

Phoebe groans from that action but blushes as she imagines Fionna riding her cock or pound her heated pussy.

Minerva smirks and nearby, another interesting moment was seen with Susan and Frieda while a Minerva with a cock equipped approached them.

"Hehe… so the powerful seeker and her sexy engineer wants some tasty sperm huh?... will say didn't expect you two to be back… what changed your mind you two." Minerva said when she approached the duo.

Susan chuckled.

"Well, after seeing parts of the world, Frieda and I talked about settling down and find a possible surrogate."

"Hehe, possible Susan or Frieda Jr?... maybe they can take a special Seeker program I'm making… makes it so that the augments are temporary and based on emotions and stress… could work in making you not as bulky Susan… more in line with normal looking humans… your call but all in all I suggest taking it since it can be a boon not having your body limited like it is… pretty sure getting through normal doors can be a pain." Minerva said before she sweatdrops as she looks at a Susan strong esk sized head hole in the doorway nearby which had to be made because Susan couldn't fit normally.

"Hmmm… you do have a point." Susan said.

"Yeah… still thats for later… for now… ready to see what Fionna could do if she was in my place with me being a demo of her?" Minerva said with a smirk on her face as she stroked her own cock before Frieda and Susan.

Frieda blushes as Susan smirks.

"Oh I'm ready alright."

"Good… I'll let you two decide who gets fucked first." Minerva said when she smirks at the duo… only one cock on her after all.

Susan looks at Frieda.

"Want me to go first or you?"

"Hmmm… I'll let you go first Susan… her cock does look YOUR size." Frieda said with a smile on her face.

Susan smiles as she kissed Frieda on the lips.

Frieda moans into the kiss while Minerva smiles at how sweet this was.

After the kiss, Susan looks towards Minerva with a lustful look.

Minerva smirks at this and she crawls on the bed toward Susan.

"So… considering things, got the foreplay or needed wetness so I can fuck you… or need a lube applied and I skip the foreplay?" Minerva asked while she opened a compartment on her body and pulled out a lube she could apply on her cock if needed.

Susan smirks.

"Get the lube." She said.

Minerva chuckles as she applied the lube and puts the bottle back up when the cock was well applied… after she did… she looks at Susan.

"So… want to lead or should I?" Minerva asked while she stroked her slickened cock to get the lube all over her cock properly.

"Hmmm… you lead." Susan said.

Minerva nods and in no time she had Susan on her back and aimed her cock at Susan's folds and slowly forced her cock inside of Susan's folds.

Susan groans as she felt her folds getting penetrated.

Minerva growls when she got pretty much balls deep after a little pushing against Susan's cervix.

"Ohhh… so deep… maybe Fionna will have a better time… I'm using Marceline's size… and she is an inch or two bigger… maybe if Fionna learns a spell or takes special nanomachines to make herself bigger for a woman like you… pretty sure maybe Fionna's size is perfect or… want cervix busting deep?" Minerva asked while Frieda blushed when she heard this and could see how deep Minerva was in her girlfriend/possible wife.

Susan smirks at Minerva.

"I would say… both."

Minerva looks amused.

"Well may as well give a taste for now by doing this!" Minerva growls when she starts thrusting her hips making her cock barrage Susan's folds while she gripped Susan's hips.

Susan groans a few times as she felt Minerva get rough with her thrusting.

As Frieda blushed… some royals waiting for Minerva bots to come to them blush when they heard Fionna on her end as her thrusts got erratic with Marceline.

"F-Fuck… I-I'm… about to… to…" Fionna muttered while she had a strained look while Marceline looks amused when she enjoyed how hard Fionna was fighting to keep from climaxing as Fionna worked to have her cock go balls deep inside of Marceline more and more until…

Fionna groans loud before she pushes her cock deeper and climaxed hard inside Marceline's snatch.

Marceline moans from this when she came hard on Fionna's cock while her toes curl from the feeling as Fionna grits her teeth when she came HARD in Marceline's womb and pussy overflowing her in no time…

Some of the females that saw blushes brightly when they saw how fertile Fionna was before seeing the heroine lean down and actually kiss Marceline during the orgasm.

After the duo ride out their orgasms, Marceline smirks when she looks down at a panting Fionna who had to recover from how much sperm they unloaded in such short time.

"F-Fuck… so much." Fionna said between pants.

Marceline smirks as she leaned down and smirks at Fionna.

"And yet I have yet to fuck those tight holes of yours." Marceline said but before more could be done… a large white and yellow paw came from out of nowhere and wrapped a few times around Marceline making her blink in some surprise as a voice was heard.

"You got some explaining to do missy."

This made Marceline look over and smirks when she saw Cake.

"Hehe, well celebrating Fionna's birthday… thats what up…" Marceline said when she smirks as she wiggles her hips making her cock wiggle inbetween some loops that could have it bee seen by Cake.

"Want in?... pretty sure at this point while you could save Fi's remaining virginities, you take me away Fionna is going to be pretty mad with you…" Marceline said with a smirk as she made her cock wiggle more so Cake could feel it in her enlarged paw.

Cake could feel it before hearing Fionna speak.

"D-Don't take her Cake. I need her." She said.

"What?... need her?... baby you hear yourself?... maybe it was wrong of me to not teach you tiers and stuff but you think Marceline the Vampire Queen would want anything serious?... come on we both know she has a thing for Bubblegum… even if you did things what are the chances she actually sticks around?... this isn't a matter of just learning sex honey its a matter of connection… and no Marceline before you open that mouth while I do have two ladies, they were in a relationship first… so they asked me to join in as their surrogate and stuff so I get the idea your going with, you just have to explain to Fionna on WHY I should let this happen… forget the immortal VS Mortal thing… pretty sure Bubblegumh as something planned with you being here… no way would you have sex without Bubblegum's permission… she got a spy drone or something?... heard she had a few of them flying around occasionally around her kingdom for security and stuff…" Cake said while she sniffs around and when she picked up something metallic and sweet… she hums as she used her free hand and knocked the drone from the air when she used a wide hand of sorts making it tumble to Cake's bed and when she saw the dent, she gripped it.

"Aha!... knew it… wonder if Bubblegum is the only one looking through this…" Cake said when she saw the drone appear and Bubblegum's voice was heard from it a moment later after Cake used a part of her to reach and grab the drone.

"Well no use hiding things now. Sorry for spying on you Fi but hopefully you, Marceline and Cake can hear me out." Bubblegum said.

As Fionna looks confused by this… a hologram projector shot from the drone and in no time… well Fionna blushed BIG time when she saw that on the other side of the room was a large bed, holographic of course with Fionna seeing MANY royals with Minerva bots while Bubblegum on her end lightly moans when Huntress Wizard was sucking her cock while Cake got wide eyes from this when she saw this as Marceline looks amused when she didn't do anything when she looks at Bubblegum.

"Couldn't resist being the peeping princess eh Bonnie?, didn't know there would be others on this spying party… that Phoebe I see getting it on with Fionna's mom?" Marceline said while she smirks at Bubblegum… guess Marceline had no idea on the drone and people looking but didn't mind both.

"Pretty much. Reason I had them here was for a interesting compromise regarding Fionna." Bubblegum said.

"Compromise?" Cake asked when she looks bewildered.

"Pretty sure if I can take a guess… mainly them coming to a deal to not bum rush this place given our pretty futa adventuring hero is a fully mature and legally aged woman now… pretty sure if not for Bonnie… most royals would try and fight for Fionna here… that right?" Marceline said when she looks amused before she looks at Cake.

"Hey mind letting me go?... pretty sure the holding isn't needed." Marceline asked while she looks amused as she relaxed in Cake's large paw.

Cake raises an eyebrow before she let go of Marceline.

"Ah… much better… so Bonnie whats the main reason or two to talk Cake into not kicking me out and letting me get Fionna's virginities here?" Marceline said when she sat next to a now sitting Fionna who blushed when Marceline gripped Fionna's ass.

"Two reasons really, a third will be used for why you should let Marceline continue once I get over the first two main reasons… one Cake… you see this many Royals?... let me tell you thanks to the space… what you see is mainly just the front part of the bed in a special room I have made… about 1/5th…. Pretty much EVERY Royal on Ooo is here minus LSP… and more like Huntress Wizard as you can see, Susan Strong, Frieda, Canyon, and many more… if I didn't hold them here for this meeting… think you could take all of them on in holding them off from getting to Fionna?" Bubblegum said as she went over reason one… or the start at least to try and get Cake to realize how many Royals were in the room with Bubblegum and how many Cake would have to deal with if not for Bubblegum's meeting call for them.

Cake was quiet for a bit and knew even her stretching powers were not enough.

"Fair point."

"Yup… second reason on why you should let this happen… think a virgin like Fionna would even survive the eagerness of many females here?... as you can see with Phoebe, some can form cocks of their own… pretty sure a virgin unprepared would be overwealmed by one of them." Bubblegum said while gesturing for Fionna, Marceline, and Cake look to the hologram version of Phoebe moaning when she was about to climax… and funnily enough Minerva kissed her making Phoebe muffly groan as she pretty much blasts such heavy dense sperm so hard it shot off as Bubblegum looks shocked.

"My ceiling!" Bubblegum said while not expecting that kind of explosive change from the kiss with the unstableness being forced from Phoebe's cock boosting her ejaculation… this left Phoebe in a happy daze when she tapped off as Marceline was laughing her ass off while Fionna who saw that… well…

The heroine actually felt turned on when she saw her mom and ex in the act which made her cock get hard.

Bubblegum groans when she saw the damage and she looks to see Fionna worked up now.

"As you can see Cake… I'll have to make Fionna fire resistant at best or flameproof at worse with various injections or alterations with some cybernetics… mainly so Phoebe here doesn't blow a hole in them like they did with my ceiling…" Bubblegum said while Phoebe chuckles in a pleased if somewhat nervous way… though Bubblegum looks at Cake now.

"The reason why you should let Fionna do this with Marceline… well she has a low chance of knocking Fionna up, a VERY low chance, so small that it would be nearly impossible… if it happens, it happens, if not it doesn't… as for after… pretty sure unless Fionna comes to us, she may get calls to other kingdoms with various other women… pretty sure Fionna should worry more on having a will of iron or having lots of experience… when it comes to sex now… pretty sure both are weak right now… so yeah… Marceline is more or less giving Fionna experience she will need because sooner or later someone WILL try and have fun with Fionna… the numbers here do not lie… as for what I want… well mainly not only helping Fionna… but seeing if she can be a good surrogate in case things do happen… don't worry Cake, if you're worried about tricks and stuff, I can make a Royal promise if needed on things if you want to be assured on some matters… either way will ask before you ask things… want to help Marceline with teaching Fionna tiers?... pretty sure it will help since… unless she lost her hymen training… this will be a… painful event for Fionna for a moment before the real pleasure happens.' Bubblegum said while she looks at Cake to see what she thought.

Cake was quiet for a bit.

"Despite what just happened… may as well help Fi since she's my sister."

"Hehe… in name only… pretty sure with how virile Fi here is… you could be having an interesting explanation to do with your two ladies." Marceline teased when she smirks at Cake.

Cake blushes before frowning.

"Don't make me spank you."

"Hehe that a kink of yours?... Bonnie does that a lot to me when we got to the hidden BDSM dungeon she has." Marceline teased while Fionna blinks.

"BDSM?... not sure what that is but if its a dungeon can I go there?... sound like it would be fun." Fionna said… oh the sweet sweet innocence… will be shed soon.

Marceline had to hold back her laughter.

"Oh it is… but not the type of dungeon you're thinking of." She said.

"Really?... well if its intense, don't worry, I can take anything in that dungeon." Fionna said as Marceline fully busts out laughing before she looks at a blushing Bubblegum.

"Hehe, hear that?... better get the wolves, horses, and Morlock's Lion body Bonnie for one hell of a gangbang while we get even freakier stuff." Marceline said with a grin on her face.

This confused Fionna for a moment while Cake blushed as Fionna starts to realize what was said, piece things together… and REALLY blushed now compared to Cake when she realized what she just said…

"Wait… it's a tier based dungeon isn't it?" Fionna said.

"Hehe the tier 15 type all the way hehe!... won't lie, if you want a sex dungeon with prizes, pretty sure Bonnie can think of something… maybe use that Dungeon train thingy she found once thanks to your stories and stuff, could be a fun time with randomized sex dungons without much worry on actually putting the thing together hehe." Marceline said before she laughs again.

This made Fionna blush more from this as Cake just facepalms.

Once Marceline calms down, she chuckles as she looks at Fionna and Cake.

"So… you two ready to have threeway fun while many eager royals watch?" Marceline said when she had a full power erection again in no time.

Fionna continues to blush as Cake shrugs.

"May as well since they are watching."

"Nice… mind taking an altered form so you can be pleasing to the eyes to many here?" Marceline said when she smirks at Cake.

Cake just nod as she uses her powers to give her body a very nice shapely form with wide hips, D size breasts and a big ass.

Fionna blushed brightly from this and Marceline smirks when Fionna's cock got fully and REALLY painfully erect when Fionna eyed Cake in her hot form.

"Looks like someone likes that form." Marceline said in a teasing tone.

Fionna blushed brightly from this as she couldn't deny what was said as Cake rolls her eyes.

"Baby many enjoy these buns when I make them just right… pretty sure you can't help but stare if I make my trunk as full of junk as Bubblegum baby." Cake said with a smirk when she made her ass an exact double of Bubblegum's ass.

Marceline was amused.

"Guess Bonnie has some competition on that area then."

"Hehe, yeah… granted can't keep it all the time so guess Bubblegum is the Bubblebutt Queen while I'm the princess but don't think I'll be going down fast if you want to take me on." Cake said while she approached the bed to Marceline and Fionna with swaying hips making her luschious ass sway in ironically enough, many Royal's views.

Fionna blushes from this as Marceline licks her lips.

"Not at all. I love a good challenge."

"Good." Cake said when she moved to push Marceline on her back and Cake smirks when she moved to get on the bed and moved to lick at Marceline's cock with a scratchy tongue which Fionna saw.

Marceline groans as she felt that action as Fionna wondered what she can do.

Cake on her end smirks when she looks at Fionna and moved to slap her ass near Fionna… seems like if Marceline got the licks and sucks, Fionna would handle the backside of Cake.

Fionna blushes a bit but seeing that display made the 18 year old heroine get behind Cake.

Once on her knees, Fionna gulped before she start to eat out Cake's folds.

Cake groans from this while she moved to stroke Marceline's cock with a paw like hand while she used a finger to finger Marceline's folds.

"Oh fuck." Marceline groans as Fionna kept up with her licking.

As this happens… Bubblegum on her end smirks as she pets Huntress's head while many Royals watch as Fionna ate Cake's folds out more.

"So far so good." Bubblegum said before groaning as her cock was being sucked by the wood nymph.

Huntress on her end looks amused when she enjoyed how Fionna was taking charge with Cake and sucked Bubblegum off harder… she fingers Bubblegum's folds while enjoying how sweet tasting Bubblegum's cock was.

"Oh fuck… really take my cock." Bubblegum groans.

HW on her end really looks amused when she deepthroats Bubblegum's cock… so much so she nearly takes all of the cock surprising and impressing Bubblegum greatly.

"F-Fuck… Guess Marceline isn't the only one to… d-deepthroat a cock." Bubblegum moans as her toes curled on the floor.

HW on her end looks really amused as she sucked Bubblegum's cock harder and faster with various bobs as she felt Bubblegum getting closer and closer until…

Bubblegum groans a bit loud as she throws her head back and climaxed inside Huntress's mouth.

HW on her end muffly moan when she felt this and worked to drink the sperm as best as she could while making sure not to spill much sperm so barely any escaped her lips.

Bubblegum was impressed when she saw that as she rides out her orgasm before tapping off.

After this happened, HW licked Bubblegum's cock clean, she pulls her head back and smirks at Bubblegum.

"Very virile… pretty sure if you fucked anyone besides the Vampire Queen, unless you made your body impotent on command, pretty sure you could knock up anyone with this load… well besides a Wood Nymph unless multiple tries are done… hard to impregnate without a bond after all." Huntress said while licking some sperm from her lips.

Bubblegum did blush at first before smirking.

"Well… wouldn't stop me from trying."

HW really looks amused.

"Good." HW said when she pushed Bubblegum so she laid on her back and HW got on Bubblegum's lap and moved to aim Bubblegum's cock at her folds… HW groan when she lowered her body and her folds took in Bubblegum's cock.

"F-Fuck!" Bubblegum groans as she felt how tight HW's pussy was.

As this happened, Phoebe watched as things were kicking off and blushed when the Minerva she was with moved to get on her lap.

"So… ready to have fun?" Minerva asked when she smirks at Phoebe teasingly.

Phoebe blushes cutely.

"Y-Yes."

"Good." Was all Minerva said like she was echoing HW and like HW, Minerva moved to aim Phoebe's cock at her folds and Minerva moan when she took Phoebe's cock deep inside of her pussy.

Phoebe groans as she felt her cock getting squeezed by Minerva's folds.

"Ohhh… so… hot… definitely need to have Fionna buffed to resist the heat before coming to you…" Minerva groans when her internal temperature skyrockets immensely.

"A-Ah… and you're so… tight!" Phoebe groans.

"Hehe… well I am a sexy robot milf… better get ready because if you can't keep up with me… pretty sure once Fionna gets trained properly… she will be able to outlast a cutie like you." Minerva teased before she starts riding Phoebe's cock while Minerva moan at the feeling.

Phoebe starts groaning a few times as she felt her cock touching all of Minerva's spots.

As Minerva keeps this up, Fionna on her end couldn't help but look over and blushed when she saw how intense her mom was with Phoebe while Phoebe looked like she was loving the feeling as she lets Minerva ride her cock more.

'Wow… Phoebe seems to be really enjoying my mom for the moment.' Fionna thought.

She than heard a groan and looks back with a blush when she watched as Marceline forced Cake to deepthroat her cock and blasts sperm in Cake's maw forcing her to drink Marceline's load.

"H-Hehe… that's right kitty… Drink all that cream." Marceline said as her cock throb.

Cake muffly moans from the taste while she drank the sperm with a blush on her face… Fionna blushed more when her cock looks painfully hard now.

Fionna couldn't handle the erection now before she surprisingly brings her cock… to Cake's folds.

Cake blinks at this when she felt that and after Marceline tapped off… she pulled her head back and looks back at Fionna with a cute blush on her face making her look adorable.

Fionna blushes from this before saying this.

"Sorry Cake." She said before pushing her cock deep in Cake's pussy.

"O-OH!... fuck!" Cake groans while Marceline looks amused when she looks to see a bulge forming in Cake's womb when Fionna didn't show her sister mercy when she forced her cock deep inside of her adopted sister's pussy.

Fionna did groan from the tight squeeze before she starts thrusting her hips back and forth.

As Cake groans, Marceline wondered what Fionna was thinking since she was getting pretty lucky with Marceline herself and Cake right now.

'Glob… can't believe I'm actually fucking Cake. And earlier I lost my V-Card with Marcy… this is actually… best birthday ever!' Fionna thought.

Marceline looks really amused when she could guess the best birthday part given how predictable Fionna was… Marceline though did get up when she floats around and well… she got behind Fionna.

"Hehe… hey Fi… you know that this birthday won't be done until I or maybe Cake take your pussy virginity and anal virginity… won't lie… first times hurt… but believe me it feels SOOO good getting fucked by a well hung cock… can fuck you now so I'll let you pick… want me to get your pussy or your ass while you fuck your sister?... can let her get what I don't get." Marceline said while she licks her lips eagerly.

Fionna blushes brightly after hearing that.

"F-Fuck my… P-Pussy."

"Hehe… you sure?... if thats the case got a cock shape?... horse?... cat?... dog… human?... Dragon?... skies the limit so may as well make sure your virginity is taken by a cock to your desire." Marceline said while she had a throbbing erection now.

Fionna was quiet for a bit.

"Go… wolf."

"Ohhh… how… Knotty…" Marceline teased while she reformed her cock to look like a Dark purple wolf cock that looked massive… though was a few inches shorter at 10 or so inches but that was to allow Marceline to use the massive knot on the cock's base that was 2 inches wider than the main inches that the cock had… so from tip to base, 3 inches in width aside the pointed tip, 5 for the knot that can swell to look bigger and Marceline smirks when she wondered if Fionna has second thoughts.

Fionna gulps a bit.

'Very big.' She thought.

"Now… ready to become a full on woman?" Marceline said when she stroked her cock behind Fionna.

Fionna blushes cutely.

"Y-Yes."

"Good… want to finish with Cake or want me to make it so instead of you doing the fucking… the two of us fuck you?" Marceline said while she gave Fionna a lustful look.

Fionna was thoughtful for a bit.

"The second one."

"Alright… Cake… get ready to thrust those tasty buns back… going to want to distract Fionna from the pain." Marceline said when she looks at Cake mainly now.

Cake did groan before calming down.

"O-Oh I'll thrust alright baby."

"Good… now try and relax Fionna… on 3 I'll thrust OK?" Marceline said when she got behind Fionna and aimed her cock at Fionna's folds.

"O-Okay." Fionna said before she took a bit before she was calm.

"Alright… 1…" Marceline said before she used her speed to rapidly thrust her hips when Fionna was off guard and her cock was rammed deep inside of Fionna and her hymen was ripped away and blood leaked from her folds while Marceline made sure not to have the knot enter her.

Fionna's eyes widened at the feeling.

"Fuck!" She groans from the pain as the females that watched, cringed.

Marceline stayed still while she waits for Fionna to adjust… she could smell tears from Fionna and Marceline moved to fondle Fionna's breasts from behind while licking and nipping at her neck to tease her.

Fionna groans from the fondle which slightly helped lessen the pain.

Cake on her end looks back and moved to kiss Fionna when he made sure to massage Fionna's cock with her folds moving around.

Fionna was at first surprised from the kiss but this also helped as she starts to feel better.

After a bit… Marceline lightly thrusts her hips to make sure to check to see if she can move yet.

Fionna did groan from that action before she sent Marceline a thumbs up.

Marceline mentally smirks when she moved to thrust her hips hard and fast now while she makes sure to use more power making her cock bash by Fionna's cervix a number of times now.

Fionna groans a few times before Cake starts thrusting her hips back and forth.

In no time this results in Fionna getting a fucked up look on her face and after Cake pulled her head back to let Fionna moan and groan… well funnily enough…

"Oh fuck! So fucking good!" Fionna moans.

Marceline grins when she fucked Fionna harder.

"Hehe… hear that Cake?... looks like your sister will be enjoying it when you bust her ass wide open later." Marceline growls when she fucked Fionna harder making her cock glide in and out of Fionna's folds while Marceline's knot hits Fionna's pussy lips again and again and threatened to bust into Fionna if Marceline got rougher.

Cake smirks as she thrusts her hips more.

"N-No doubt about it."

"Well let finish her off and if she is able… may as well make sure she can even get on all fours or something to take your cock!" Marceline growls as she starts fucking Fionna hard and fast now to help Fionna feel better than ever.

Cake growls as she thrusts her hips faster and harder making Fionna's cock go deeper in her pussy.

This made Fionna on her end groan more while Marceline and Cake please Fionna more… so much so that they could feel Fionna getting closer and closer until…

Marceline groans as she goes balls deep and gives Fionna her first creampie that heads straight for her womb after Marceline forced her knot into Fionna and her knot quickly inflates as Cake climaxed on her adoptive sister's cock.

Fionna on her end had a shocked and pleased look when she felt something in her go off, more so when the knot quickly inflates and she really groans with eyes rolled back, tongue hanging out of her mouth, and her body felt like she was having a full body orgasm when she came hard on Marceline's cock while sperm overfilled her folds as sperm blasts from Fionna's cock and into Cake's womb while Fionna's balls throb and clench with each shot and overfilled Cake's womb after making Cake's womb bloat a bit.

This made Cake's climax get stronger as the trio rides out their orgasms before Marceline and Cake tap off.

When this happened, Cake and Marceline, after Marceline enjoyed the afterglow, reformed her cock to not have a knot as she pulled her cock free and Fionna fell to lay on the bed with a fucked up look on her face as sperm leaked from her pussy with some blood while Marceline smirks as she enjoyed the sight.

"Hehe… nothing like a busted in virgin to get one worked up… so Cake… ready to fuck Fionna's ass?... and Fionna… ready to continue or want to continue when you get a second wind?" Marceline said while she had a hand on her hip.

Fionna got a dazed look on her face.

"M-More." She said.

"Well… you heard her Cake… form a cock and while I have Fionna clean me off, get ready for tight human bun fucking." Marceline said when she smirks at Cake.

Cake smirks back before she uses her shapeshifting powers and summons a cock that was a size of a big lion cock.

It was Marceline's initial size so the 12 incher with a 3 in width thing with MANY barbs on it… Marceline on her end smirks as she moved to stroke Cake's cock while she muttered something and a lube formed on Cake's cock which Marceline stroked onto it aggressively to get Cake worked up.

"F-Fuck." Cake groans as Fionna was able to see this.

When Marceline got the cock fully lubed, she smirks when she stands and used a spell to clean her hand off…

"There… now you should glide into that hole like ice cream being melted by a hot spoon." Marceline said while she slapped Cake on the ass so she could approach Fionna and her unguarded ass.

Cake did groan from the smack before smirking at Fionna as she got closer.

As Fionna blushed from seeing this… all she had was one thought as her sister got close.

"Again… best… Birthday… ever…" Fionna thought as Cake gripped her ass cheeks and aimed her cock at Fionna's asshole… before more could be seen though the scene fades to black as a piercing sound and a strained groan was heard as Cake worked to teach her sister more on tiers with Marceline backing her.
