Night 1: Let the fun begin

"Okay Vinyl, dinner should be done in a few minutes. I'll call you down when everything's ready." Octavia said as she placed a fresh pot of water on the stove.

Vinyl simply nodded before going upstairs, almost immediately loud partying music could be heard. Downstairs a supernatural portal suddenly opened up and the spirit Desire flew out laughing manically.

"Yes! Freedom! It's be so long! Now I can cause endless chaos and wreak havoc on all you mortals and-oh what's the point? I'm just gonna get defeated and get sucked back into my own realm, again. Man, I'm in a rut. An endless loop! I need to try something...different this time. But what? Eh, I'll just wing it I guess." she said with a heavy sigh.

She turned into a purple gas form and floated upwards phaseing through the ceiling only to have her head appear on the kitchen floor, there she watched as Octavia was busy cooking dinner throwing in different spices in a large pot of homemade sauce. Desire sniffed the air and gagged in response.

"Ugh, what is she making? Barf casserole? " Desire said rolling her eyes.

Suddenly there was a loud ding sound.

"Oh! The spaghetti's done!" the earth pony squealed as she excitedly put on her mitts before opening the oven and began pulling out a hot tray of spaghetti.

Bending over gave the unsuspecting Desire a clear crisp view of her large curvaceous backside, her eyes grew wide as the earth pony swayed her hips side to side humming along to a peppy tune.

"Oooh, baby got back I see. Hmmm, it's been forever since I actually fully possessed anyone. I hope I still got it." Desire said as she smiled wickedly.

The female spirit  hovered just a few inches above the mare who was still taking in the heavenly smell of her freshly prepared spaghetti, she cried out in surprise as she felt Desire beginning to seep her way into her large pillowy ass. Button mash's mom threw her hands back to try and grab the intruder but her fingers simply passed through the spirit's tail as it slipped inside with one final slurp sound. She groaned aloud as she began to walk around the kitchen aimlessly. Her entire body shook violently as the intruder inside her fought for complete control of her body. Finally Octavia fell to the floor unconscious only to wake up a few seconds later with a wicked grin on her face. As she got off the floor and stood, her mane slowly began to grow longer in length until it reached her waist and took the form of Desire's usual hairstyle as her skin glowed with new life. She then giggled with joy as her light tan brown breasts inflated to an E cup going along with her slightly bigger yet firm backside, she gave it a hard smack causing it to jiggle wildly sending waves of pleasure up her spine.

"Oh God! It's been forever since I felt this good!" She sighed as she played with her new oversized breasts.

Upstairs Vinyl started to grow hungry and was wondering what was taking so long. She quickly got out of bed and tip toed downstairs before poking his head in the kitchen to make sure if everything was alright, he was surprised to see her butt naked as she was bending over to look inside the fridge.

"T-TAVI!" She yelled as she covered his eyes.

"Hm? Oh, hello Vinyl! Sorry dinner is taking so long so I thought we should skip dinner and move on to...desert." She said as she pulled out a can of whip cream.

Vinyl slowly opened her eyes again and realized that her roommate was speaking in am entirely different voice while also noticing the hertra long mane much unlike how she usually kept it.

"You're not Tavi. Who are you and  what did you do to her!?!"

"Why, Vinyl  I'm standing right here. Now why don't you come over here so I can give you a special treat for being a great roommate." the imposter said as her eyes glowed an eerie red aura.

Vinyl gasped as the door behind her slammed closed followed by a swift click sound, realizing the situation she began to panic for she had no idea who this imposter was or what her intentions were. That soon changed as Vinyl could feel her senses going numb as he stared into her hypnotizing eyes, the Dj pony soon lost control of her movements and was being driven forward only to stop inches away from the mare. In response Desire uncapped the bottle and sprayed whip cream on each of her tender nipples and held them both in each hand. Vinyl gulped aloud before slowly sticking her tongue out, Desire smiled as she finally came in contact with her right nipple then proceeded to lick her nipples clean of the tasty cream much to her sexual enjoyment. The imposter then ordered her to get on her knees which she immediately did so allowing Desire to spray a dollop of cream on the tip of her nose before licking it off leaving a trail of saliva up to her forehead, she shuddered with happiness. Taking the whip cream can again Desire shook it a few times before filling her exposed pussy to the point where cream was overflowing from it, she then grabbed the back of Vinyl's head and buried her face inside her cream filled crotch crying out in excitement as she began to eat her pussy out like a delicacy.

"Oh yes! Oh fuck yes! Ah! Put your tongue back in! Ahh!" she cried out before cumming all over her face.

Once Vinyl had finished scrapping her pussy clean of the cream and the last of her juices Desire tapped the top of her head sweetly implying she did a great job before turning around giving a close up look at her plump, juicy fat ass. Taking the can once more she spread her ass cheeks apart exposing her tight puckered asshole.

"Hope you're still hungry." She sighed as she filled her ass crack with the cream.

Vinyl licked her lips before grabbing her ass on both sides and burying her face inside licking away between the imposter's asscheeks, she moaned in deep arousal for it was centuries since she felt something like this. Once the last of the cream was licked up  Vinyl laid down on the floor completely exhausted, she gasped as Desire climbed on top of her guiding her finger up to her jacket zipper and pulled it down exposing her breasts before taking her right nipple and sticking it inside her mouth. Vinyl gasped as a cloud of purple smoke began to leave her body which the imposter swallowed immediately before letting out a small burp, the Dj shuddered wildly before going completely limp and unconscious.

"Hmmm. Her lust had a pretty sweet taste to it." She  laughed evilly right before growing a few inches taller as her coat turned a darker shade.

"Still sucking mortal life forces Dessie?  Heh, and I thought you were more daring than that." A new voice laughed.

Desire spun around to see two figures floating in midair, at first glance they looked like regular female ponies but their intimidating sharp teeth and sluttish outfits told a different story. They were both members of the dreaded Succubus species, a small number population that dwelled in one of the deepest darkest pits of Tartarus only to surface periodically to wreak havoc on the mortals while also fulfilling their lustful desires in the process. The first pony was tall, thin, with big bouncy breasts and a well rounded ass. She was wearing a simple purple blouse and white undershirt that revealed her cleavage with tight fitting  jeans that hugged her curves, her glossy purple coat and orange mane practically glowed underneath the kitchen light. As for the second pony she was thick and curvy with a big thunder ass and well proportioned breasts that jiggled with every movement, she wore a simple white dress that had a hole in the center of her chest displaying her rack of goods and like her sister her silky grey coat and white mane looked smooth to the touch and glowed in the kitchen light. They both had jet black bat wings and long slender tails that ended with a triangular point.

"What do you two bimbos want?" Desire snapped at them.

"Whoa, no need for the name calling Dessie. We were just wanted to check up on you and make sure you're alright." The first succubus pony known as Violet Rose said as she lowered herself to eye level with Desire.

"What do you mean? Of course I'm alright."

"Really? Cause we've been hearing you crying your eyes out every night for over a month now. Please tell me your not still hung up on that human."

"What!?! O-Of course not! Like I even give two shits about that limp dicked loser." Desire yelled as she slightly blushed.

"Mmm-hmm."

"Listen Violet, no offense to you or your whore of a sister-"

"None taken."

".....Right. But I'd appreciate it if you left me alone now."

"What? And let you have all the fun up here, as if." The second succubus known as Silver Moonlight snickered as she floated right next to her sister.

"What fun?"

"Ahem." Silver said as they all looked down at the still unconscious Button mash still laying on the kitchen floor.

"Now Dessie, you for one should know that our kind isn't supposed to be out and about around this time of the year. It would be a shame if Queen heard about your disobedience."

Desire's eyes grew wide as her skin turned pale, Queen was the most respected and most sought after leader of the Succubus race and her strict rules forbid any member of said race to be out around this month. If word got out that Desire did so she would become Queen's personal slave and sex toy for who knows how many centuries, several shivers went down her spine.

"I-I-It was just a one time thing, please don't tell Queen. I beg of you." She said with pleading eyes.

Silver and Violet shared sly glances with each other.

"Sure, we won't tell Queen." they both said in unison.

Desire knew that look in their eyes, they wanted something out it. She sighed heavily realizing how desperate she was in this situation.

"A contest."

"A what?"

"Well since you like taking virginity so much, let's have a little competition to see who's takes the most virginity in one night." Violet declared.

"Interesting idea sister. How do we do that?" Silver asked, her eyes beaming with interest.

"Simple. Since using our powers are more likely to raise suspicion each one of us will possess one mortal and using said mortal we go hunt down every virgin in town."

"Specific gender?"

"We did all females last time, so this time let's go for the guys to be fair."

"Rules?"

"Free-for-all. No rules except you can't leave your host body. Agreed?"

Desire shook her head and sighed but figured a silly competition was better than a cold night in Queen's dungeon.

"Okay, fine."

"Great, so I'm guessing you're sticking with the middle fancy middle aged bimbo look?" Violet said with a teasing smile.

"What? Afraid my giant ass will put both of yours to shame?" Desire said turning around and teasing the two with her curvy backside.

"Laugh while you still can, just don't bitch when we beat you fair and square."

"Ha, whatever."

Before the contest could officially began the two needed a host body to preform in and Vinyl's body wasn't much without lust, they phased through the walls of the house and looked around for a potential victim. A few minutes later a certain purple coated and pink maned pony was strutting down the sidewalk carrying a handful of school supplies and paperwork, Silver and Violet smiled wickedly at each other before shifting into two separate purple ghostly forms and flew over to the pony's direction. Violet tapped Cheerilee's shoulder causing her to turn around and look behind only to see no one there, she turned around again to face a phantom ghost. The cloud flew closer to  Cheerilee and squeezed her mouth open, a pair of full buttery lips phased into view before being placed onto Cheerilee's and gave her a big seductive kiss causing her to drop her belongings in surprise and shock. The fog still squeezing the mare's mouth open quickly squeezed into her mouth, Cheerilee whimpered in fear as she tried using her muffled voice to cry out. Violet's upper body flew in a rapid pace as Cheerilee's throat bulged out, she could feel the figure take room in her stomach.

"Coming through!" Silver yelled excitedly as she flew into Cheerilee's still open mouth only to stop at her giant ass.

Silver's lower body began wiggling frantically a she tried to push herself inside.

"Oh, Tartarus! I'm stuck!" she said  as she floated back out only to turn around and try to enter bottom first.

This caused Cheerilee's mouth to open even wider as Silver forced her large backside in first, and with a loud 'pop' she began entering the mare's body. Cheerilee tried grabbing the spirit by her thick hips and tried gripping on it, but it was no use. 'Fwoooop' was the noise that was made as Silver completely entered the mare's body, Cheerilee then collapsed onto the ground. A few seconds later she woke up with an evil grin on her face.

"Wow, it really has been forever since we inhabited a mortal body." She said using both of the sister's voices in unison as she stood up and began groping her medium sized breasts and ass groaning with pleasure.

"So, this is your style? Posing as a simple flat chested  school teacher? Hmph, and you talk down to me about being daring." Desire laughed as she walked into view.

She was now fully clothed wearing a sexy black tanktop underneath a black leather jacket, a short miniskirt, and heels. Her mane was now in the form of a super long ponytail.

"Oh, we're not done yet. Observe."

Cheerilee stuck her thumb inside her mouth and began to blow, almost immediately her bust sized ballooned up to a Double D cup causing the buttons to her blouse to pop one by one revealing her black laced bra as the fabric to her skirt was being stretched to it's limit as her ass practically doubled in size. Her new bouncing ass cheeks were spilling over the top of her over stretched skirt.

"Now were evenly matched." She said with a teasing smile as she stuck her tongue out.

Desire rolled her eyes in annoyance.

"Anyway, I found a perfect place to put our new bodies to the test. Some pony is throwing a wild party in the center of town, I bet there's plenty of virgin stallions there."

The two walked to the center of PonyVille square, there was loud music and party lights streaming from the windows of one of the dozens of houses. On the front lawn was endless amounts of red cups and colorful confetti as well as dozens of drunken partiers that have passed out long before, Desire and Silver/Violet smiled at each other before walking off in different directions. Inside possessed purple pony was looking around sizing up the room, she spotted several good looking targets and was about to advance towards one when she was stopped by a certain peppy pink pony.

"Hey there Miss Cheerilee! I didn't expect to see you here, not exactly "your scene" if you know what I mean." Pinkie giggled.

Pinkie who had just turned 19 not to long ago  was wearing a loose white T-shirt that barely covered her big bouncing tits and black yoga sweat pants that made her ass looked even bigger. Based on her drunken posture and messy unkempt curly mane it was clear that she had indulged in a few too many alcoholic drinks already and was barely able to stay awake. Seeing this as an opportunity to get her own body to play with Silver excitedly left Cheerilee's body and flew directly into Pinkie's mouth, Violet quickly shoved Pinkie into a nearby broom closet to let the possession finish without anyone seeing. A few seconds of wild thrashing later Silver who was now in Pinkie pie's body stepped out and began stretching as two stallions walked by and their jaws dropped upon seeing Silver's inflated mountain of an ass.

"You know you could've gotten us caught by doing that." Violet said crossing her arms in annoyance.

"My apologies but you know that I can't really feel anything when we share, this way I can get as much fun." Silver said giving her ass a hard smack.

Violet rolled her eyes as she watched her sister walk off to escort the two eager stallions upstairs. As for Desire she was walking among the dense crowd of dancers to spot at least one stallion who wasn't smelly or vomiting on the floor. She then spotted three stallions sitting side by side on a red velvet couch, they seemed to be your typical introverts who barely get invited to these kinds of parties. Seeing this as an opportunity she approached the stallion sitting in the middle spreading his legs apart she began grinding her lower body against his crotch much to the delight of the nearby onlookers as they cheered.

"They were right, I did need this. I don't even remember what I was crying over."

Meanwhile, at Sweet Apple Acres.

After a long day of picking apples, making apple cider, and maintaining the farm Applejack was exhausted to the bone and collapsed on top of her bed and immediately fell asleep. A half hour later she could feel something (or someone) slipping underneath the covers and pulling down her jean shorts, she moaned in her sleep as she felt a pair of fingers massaging the edge of her outer lips only to go deeper and deeper until she finally cried out when something entered her clitoris. Her eyes shot open to see Sam inches away from her face.

"Sam! Oh my Celestia ah' can't believe it's really you!" She said wrapping her arms around him.

Sam didn't say anything, he merely lowered his head and began kissing up Applejack's neck.

"Whoa, slow your roll there partner. Ya just got back." Applejack said pushing him off her.

"All the more reason to get back in business." Sam said grinning from ear to ear.

Applejack was surprised to hear his voice, he sounded older and more mature. Taking a moment to really look at him she noticed that he was taller and was even more built than before, without realizing it Applejack traced her finger around his chest area inhaling sharply at the temptation. Her thoughts became cloudy as Sam ran his arms underneath her T-shirt cupping her double D breasts in both hands causing a quick gasp to escape her lips as she grabbed him by his shoulders. Memories of her first time meeting him flowed through her mind, but now the once timid and confused human became the tall muscular dominating figure in her bedroom.....and she wanted him.

"Now Sam, we apples are all about business and such...so I hope you're ready for the wildest ride of your life?"

"First you take my virginity, now you taking my lines? A little too far don't ya think?"

"Not far enough."

With Sam's assistance she pulled off her tan brown apple designed panties exposing her long moistened pussy to it's beloved owner, her breathing slowed as he trailed his tongue along the edges teasing her slightly while getting a taste of her all natural goodness.

"Oh quit the pre-show and get to he main event already!"

He smiled at this and granted her wish pulling out his enlarged rock hard cock that was greatly compared to a well endowed stallion cock and shoved it inside causing the farmer to cry out in sheer pleasure. He could feel her inner walls clamping down hard on him practically begging him not to pull back out and frankly he didn't want to, during his time with Desire none of her tricks seemed real at all. In fact nothing in her dimension was real, and naturally he didn't feel a damn thing. The rest of the night Applejack tried her best not to scream aloud at the force of Sam's master cock slamming against her maiden marehood biting down hard on her bed pillow as Sam's cock began to twitch inside her, it exploded with tremendous force shooting out wave after wave of his cum. Applejack simply laid there breathing heavily, despite being called the toughest female pony in PonyVille she never could really stand another round after tangling with Sam's beast. But tonight was a completely different story, she gasped as she felt his cock harden all over again as he slowly pulled out of her winking pussy.

"Oh no you don't." she said as she grabbed his cock before getting on all fours and positioning it right in front of back entrance.

Sam grinned upon seeing this, Applejack's jiggling cheeks was by far one of the biggest butts in PonyVille right behind Pinkie Pie and Mrs. Cake. It was one of the reasons why he fell in love with the pony, he dreamt of shoving his enlarged cock up her warm asshole and making her scream to the top of her lungs. He groaned aloud as Applejack began licking all over his member to lubricate it before hotdogging it between her plump cheeks, she tried even harder to keep in her lusty moans as Sam circled his tip around the rim of her asshole while using his free hand to pull up her T-shirt causing her breasts to hang allowing him to play with her erect nipples.

"Oh fuck, I see why the cows like this." She moaned only to gasp as he slapped his bare palm against her left buttcheek causing it jiggle like a giant plate of jello.

Sam could feel something burning in his chest, the need to really make this mare his and his alone.  He pulled her asscheeks apart and buried his stone hard cock inside her, the sudden insertion made Applejack scream to the top of her lungs.

"What the hell is going on 'round here!?!" Big Mac yelled as he kicked he door open, standing behind him was Granny Smith and Applebloom.

Applejack and Sam simply stood in their positions.

"Uh, howdy everypony." Applejack chuckled nervously.

A few minutes later everyone was sitting around the dinning room table where Sam told his tale of his misadventure in Desire's clutches only to escape by giving her what she wanted: a one night stand with Sam's beast.

"Well...as long as ya made it back in one piece. Applejack was pretty mopey around here without ya, guess she licked playing wit your Twinkie just as much." Granny Smith finally said.

"Granny!" Applejack said in embarrassment.

"What? I can't be honest?" Granny said with a sly smile.

"Eeeyup." Big mac said in agreement.

As everyone laughed Sam could feel somepony tracing their fingers along his inner thigh, he turned to see Applebloom fluttering her eyelashes at him. Now 16 she had grown aloud over the years (the word years is being used because apparently a lot of time has went by during his absence), she now had nearly a single D cup and was starting to show some inches on her rear and it was clear that her feelings for him only grew stronger.

"Something tells me this is gonna be a whole lot more than I bargained for."  He chuckled inside his head.

Meanwhile, in one of the deepest trenches of Tartarus

Sitting on top of a tall plush throne was the biggest and bustiest succubus mare in all of Tartatrus, her dark crimson red coat and long silky purple mane and wore a red clothed robe dress glowed with a powerful radiance yet strangely enough she greatly resembled the sun goddess Princess Celestia herself. She was resting on her beloved throne being fanned by smaller less curvier mares when a fog of black smoke appeared before her and another succubus phased into view. She was a tall slender yet muscular beauty wearing a viking helmet and clothed clothing with a  light sky  blue coat and a long stately grey mane.

"My beloveded Queen, I bring you urgent news." She said bowing before the succubus queen.

"What is it now Dream Fury?" Queen yawned.

"We fear that some of your followers might have entered the surface world and is now participating dark sexual practices."

"You could have just said sex." the giantess said rolling her eyes.

"That's not the point, it is your very own rule that we are not allowed to bed mortals around this time of year."

Queen yawned loudly in disinterest .

"My queen, we must take action before it is too late."

"Why? What's the big deal?"

"T-The big deal is that this violates your own rule."

"To be completely honest I don't really see the big attraction is up top, all they have are inexperienced stallions and mares with barely an E cup. Disappointing if you ask me, oh how I long to bed someone who are show fearlessness in the bedroom and can ravage my insides like a barbarian. Sadly there is no mortal like that left in this centaury."

"Uhhh...." Dream Fury said darting her eyes to the left.

"Do you know someone like that? If you do I command you as my scout to tell me."

Dream Fury gulped.

"Th-There is. A human mortal named Samuel who now resides in PonyVille. Desire, another dream scout had targeted him for quite sometime now and we believe her influenced has....changed him somehow. After his brief time with her she was found on her bed moaning his name, she told me that he has evolved into something not of this world and... well, I for one would like to see what this mortal can do."

The other mares whispered excitedly amongst themselves.

"Silence!" Queen yelled, the ground shook at the sudden outburst.

She then grabbed Dream Fury with her giant hand and brought her up to her face.

"This Samuel, he seems like a worthy challenge fit for a queen. Bring him to me, so I may see for myself."
