Boo's Mansion

By: Lapsa

For: Toronia

"Hm...Even in this decrepit place this strange world is colorful and bright." The small white-furred yordle's piercing red eyes slowly moved around the abandoned grounds before him until they set on the mansion at its center - the occasional whine of a metal gate behind him making him wince as he mulled over all the strange place, he found himself in had to offer. "Perhaps one of the other strange inhabitants of this place calls this mansion home...and can help me return to my own."

Asriel began walking forward in earnest; his baggy purple cloak flowing with each step he took towards the rotting wooden steps. He'd only find himself briefly pausing as the caw of a raven echoed out from above - the small figure taking the familiar sound as an omen as his gaze met the dying rays of the sun as it dipped further and further below the horizon. Even with the lack of light the strange look everything had seemed to remain, the strange softness to the world around the small figure as he started to walk once more - reaching the large door as it creaked open to reveal the darkened interior with only the distant hint of a flame in a far off room.

"Hm!" Asriel smirked a bit as he walked into the mansion, feeling the cool stale air against what little fur was exposed as his eyes fixed on that distant flickering flame. "I guess I'm not alone here after-all."

The yordle barely took a step further into the mansion before he heard the whine of the metal gate behind him once again followed by a loud clank - only thinking to turn around at the new noise reaching his ears. He'd be met with the sight of the gate now shut, the wooden bar that was detached when he entered the grounds now set up - repaired by some unseen force as it blocked an easy exit.

"Interesting..." The yordle felt almost no surprise, though the grip on his staff tightened as thoughts started to push through his mind. "Perhaps I'm dealing with something a bit more than a few sapient fungi this time."

Four piercing red eyes would push through the darkness as the yordle's tail dropped from around his waist - a snake's head at its end that hissed at the stagnant air burning at the sensitive tongue that licked around. The candle-light would become even more crisp and distinct in the distance as the four orbs adjusted to the darkness, the details of the main entrance Asriel now found himself within slowly falling into place; half-covered furniture, rotting floor-boards, a few hanging candelabras set above dusty broken tables.

"Whatever is here, I don--" The words were interrupted as the now faint light trickling in through the entrance faded away entirely - a sudden gust of wind nearly blowing off his pointed hat as a loud slam echoed through the mansion. "Hmph!"

Asriel's gaze hardened as he turned to face the now closed door - the locks and bolts secured in place an ever so faint chuckling seemed to taunt him. He'd only grip even more tightly to his staff, tail hissing as it looked around into the darkness behind him for any signs of movement. He'd find himself frozen there for a few seconds as he thought over what to do next - whether to confront whatever was in here or simply leave. It wouldn't be until the snake eyes caught glimpse of the flickering candle fading away that he'd finally make his choice - a smirk coming across his face as his expression softened once more.

"I guess I have no choice..." He turned back around, letting his eyes adjust once again before making his way through the large mansion's first floor - floor creaking beneath each step as his leather boots knocked softly on the ancient wood.

***

Asriel's exploration of the house would go by swiftly with two pairs of eyes and training in the arcane, each room scoured for any signs of magic or life. Crumbling furniture would be revealed, ancient jewelry examined, every single detail looked over for whatever had wanted him trapped so badly in this long-forgotten place. He'd almost contemplate just leaving once more as he rounded back to the main entrance again, eyes just barely catching the ruined stairs leading up to the second floor - light fluttering in through one of the few windows not boarded up or covered in thick cloth.

The yordle would let out a sigh before slowly making his way up the creaking steps - nearly falling through as a few steps buckled beneath even his meager weight. Even still he'd make his way up to the second story - greeted with a long hall that seemed to wind around the outside of the mansion - halls on the left of each as his eyes darted down both paths set before him.

"Assriiieel~" The yordle's ears would perk up at his name - the whisper almost floating on the wind as it blew into his ears - a small cackle following just seconds later echoing out through the dead halls before the same familiar voice spoke again. "Assssriiiii~"

"Who's there?" The hint of playful smugness would leave Asriel's voice as the cackles faded away - both his own eyes and the snake's darting about.

"How do you know my name!?" The yordle heard giggles mocking his question from behind him as he spun around to see nothing - his staff raised up as it flared with magic. "What do you want!?"

"Assssrrrriiiiiiiii~" Again the voice came and echoed, the snake hissing as it just barely spotted a white blur move past its motion - the yordle twirling around to stare intently down the empty hall.

"Stop playing games! Come out and sho--"

His words would be cut off as his head darted to the side to finally see the source of the voice - a pair of crazed demonic eyes staring deeply into his own; yellow and red mixing together to swirl and spin about in between outlines of black. Before he'd even be able to fully take in the details he'd feel something push against his lips, tiny hands wrenching his mouth wide before a sulfurous taste his him. He'd be on his knees gagging and choking within seconds as the figure pushed its way inside of him, vanishing completely to leave the mage writhing as prickling waves of numbness washed over his body.

"D-damn it!" The words would leave between coughs as Asriel finally managed to catch his breath, picking himself up after just a few seconds as his head began to throb. "I-I was too slow...w-where did it go!? Where are you!?"

"I'm right here~" The yordle's eyes widened as he heard the voice echo across his thoughts - feeling a weight press down on parts of his mind suddenly, sifting through each before settling itself down in a deep dark part that seemed to radiate with an unfamiliar aura. "There is so much room in here, especially if we get rid of some of these pesky little thoughts~ Maybe I should invite some friends~"

"W-what!? G-get out of my head!" The spirit's words would echo as Asriel yelled out, trying to push inside of his own mind with the magic he had trained so hard within - feeling sparks hit whatever force had nestled itself in like a hand hitting a thick wooly cloud. "Y-you have no power over me!"

"Oh~? Are you sure about that~?" Asriel would let out a growl as he felt the force nestle itself even deeper, all the while the throbbing in his head growing and growing until it was pushing at the base of his skull. It wouldn't be long after before he'd feel it move through him like an invisible force; slowly draining out into each limb as his muscles began to twitch and move on their own. "So small and feisty~ You'll make the perfect host~"

"Rrrrr..." Another growl would leave the yordle's lips as he felt his body twitch even more, every bit of his mind struggling to maintain control as he felt himself start to turn - the head of the snake on his tail now flared up with a hood as it hissed at the unseeable foe within. All the while giggles and chuckles would mock Asriel as they echoed in his mind.

"Release me! I command you to leave my head!" Asriel would shout even louder now, voice booming with anger as he briefly managed to take control of his body. "You have no power over me!"

"Its so fun when they fight back~ Its really been too long~" Once again the yordle would lose control over his body as trembling legs would slowly move him forward along the hall - the light from the window fading as he pushed forward into complete darkness; a door at his side soon swinging open as he paused in front of it. "You'll love this~"

With a few more steps Asriel found himself completely in the room - the door behind him slamming shut as soon as he entered - both the snake and his own head darting around the room as many small white orbs so gave into view. Their expressions would be just the same as the one he saw before, their tongues lolling out of their maws amid sharp jagged teeth as they swirled around before flinging themselves towards the possessed yordle.

"N-no...n-not this time!" With a grunt the yordle managed to raise his hands as a thin white barrier surrounded him - the boos slamming into it as their forms dissipated only to reform again with even more crazed expressions.

"Hey! Let us in!"

"Yeah, give us that body~ We'll take good care of it~"

"F-fuck off!" The barrier flickered as it expanded, pushing the boos back once again before they reformed - now slamming themselves against it over and over as they cackled and giggled around him.

"Awww~ That's no fun at all~!" The voice inside of his mind feigned disappointment before a manic cackle echoed out after - a burning sensation rippling across Asriel's fur just seconds later as his clothes erupted into greenish flames. "Let's at least liven things up a bit~!"

"Ugh! W-what!?" The barrier flickered as Asriel struggled to divide his focus - the flames not licking at his fur, only seeming to engulf his clothes as tattered ashes of once regal purple robes slowly fell away. Second by second would pass as he was slowly left - naked; toned body fully exposed in the aftermath, limp black cock sitting between his legs, black gloves tipping out his otherwise white coat as they raised up even higher.

"Such a cute little body you have~ It could definitely use some...improvement though~"

"W-what are yo--" Asriel's eyes shot open wide, teeth clenching as the barrier nearly completely fell. He'd feel a spark shoot up his spine, entire body tingling with a strange energy as a faint pink glow began to surround him. "U-urk!"

The tingling would reach his groin just as he felt something hard grinding against him - a thick member grinding itself between his cheeks as his snake eyes stared towards it helplessly. Both would together prove to be more than enough of a distraction to let another boo wriggle its way through the barrier, another soul that forced its way inside of him as he once again struggled to keep on his feet - mind and thoughts even more smothered as the new will imposed itself just as the first had.

"Finally~! Let's see how far we can go before the little kitty breaks completely~"

"Yeah~ We'll see how durable this little cutie's mind really is~!"

Asriel felt the tingling in his groin grow even more as a partial numbness set over it - cock twitching within his sheath as the cock continued to grind against him, now pushing between his cheeks even more firmly. Even more of his attention would be taken from the barrier at that, the flickering magic starting to wane as he looked down to see his cock starting to shrink, balls and all seeming to recede further and further away as a sickening lump formed in his throat.

"M-m--W-what the hell are you doing to me?!"

"Oh poor little kitty~" A cackle would tease. "I told you that we needed to make some improvements~"

The tingling sensation would continue as Asriel felt his cock completely fade away - little more than a tiny lump on his crotch as ethereal hands wrapped around his chest to grope at him. Before he'd even let out a yelp at the sensation he'd feel a tinge of paint shoot through each of his nipples, breasts now growing in size to slowly obscure the sight of his cock and balls fading away into nothing.

"Starting to look much better~"

"Yeah~! Almost done~"

"S-stop it! S-stop! Thi--" His eyes shot wide once again, entirely body stiffening - tail shooting straight out as he felt the ethereal cock move around to between his legs, rubbing itself along his newly formed slit as it teased against the entrance. He'd feel his knees start to wobble as it pushed against him, buckling legs giving out in the seconds that followed as it pushed its way into his newly formed passage - barrier shattering completely as the still waiting spirits rushed forward with a manic giggle. He'd be forced onto all fours at the sensation, flames of lust fanning upward and into his mind at the overwhelming force of all those souls pushing past what little defense he could muster.

"Time to break this little cutie~"

"Why don't we make some more changes while we're at it~?"

"Good idea~"

"N-no...m-my...my body..." Asriel's pleas trailed off as the tingling sensation flared up yet again. He'd feel as his muscles started to soften and fade - draining away ever ounce of strength he'd trained into his small form with only a chorus of laughs to mock his whimpers and snarls that would echo louder and louder until they drowned ut even his own thoughts.

All the while he'd feel his body reposition itself to better take the cock still pounding as his fresh new slit - the ghosts working together to rob away any control over his new feminine body he could muster beyond the few growls and twitches he'd barely manage. The yordle would be entirely helpless as he was used, the cock thrusting in and out faster and faster, seeming to get thicker and thicker each time it pushed into him, stretching the tight passage more and more with each motion as sparks of pleasure followed each.

"So warm~"

"So full~"

"So many sensations~"

"We love having a body~!"

"G-g-get out! S-stop!" The yordle's fists clinched as they sparked with arcane energy, Asriel unable to focus enough to try to cast a spell or channel magic - the cock now pushing in and out of his wet slit as his new breasts swayed with each motion, growing larger even still as they weighed down at his chest.

"Don't fight~"

"Yeah, we know you love this too~"

"It'll feel so much better if you just give in~"

"N-no...I-I...y-you hold....n-nnmmm." A hand would grab at his horns to pull his head up as his tongue lolled from his maw briefly - cock pumping even harder in and out of him; stretching his hole even more, feeling even more real than the wood beneath his hands and feet as it finally stopped growing. All the while the hands massaging and groping his breasts would continue, breasts finally levelling out to ad a DD - touching the floor now as more cackles broke between his thoughts.

The assault would go one for minutes and minutes as the yordle slowly started to find himself relenting to the pleasure - twisted body equally twisting his mind as waves of bliss tickled into the back of his mind while pink flames burned hotter and hotter to slowly burn away his will. He'd be able to feel himself pushed closer and closer to the edge, more and more pushed towards climax as he tried to grip even more tightly onto every little bit of will he could.

"What's that~? Getting so close already~?"

"Guess he liked it more than we thought~"

"Well we'll just have to fix that~"

"W-wha--?" Asriel felt the cock stop suddenly within him, teasing as it throbbed and pulsed deep within his passage - the warmth radiating out through his body and making him tremble. Even with the still groping hands at his breasts he'd feel himself stuck on the edge, body not listening to commands to rock back into the cock, mind barely able to form any sort of thought. He'd watch as ghostly hands and paws grabbed at the chord of pleasure that was so close to snapping - pulling him back from the edge and teasingly dangling him over it as they held on even more tightly than he had to his own will.

"No cumming for you~"

"No pleasure unless you submit~"

"Submission is pleasure~"

"F-fuck...n-nnmmm..." The grip would get even fighter as his slit dripped to the floor below, the ethereal cock within him just barely pulling itself back to add even more electrifying tingles to tease at the yordle. The pleasure was already too much for him to bare, too much to fight against as the snake-tail watched with an almost pleading expression at the cock stuffed into his small body. "C-c-can't...g-gotta...f-fuck..."

"Need to just give in~"

"No need to fight~"

"Pointless to resist~"

"J-just...g-nnnmm...n-no..." His hips would slowly splay out even more, rump plumping up until he could feel it jiggle each time the ethereal cock moved within him. The sight would only serve to tease him even more - some sickening pleasure taken in having been dominated and changed, mind and body twisted and contorted.

"Just accept it~"

"Just submit~"

"Can't fight~ Can't resist~"

"Need to cum~ Want to cum~"

"N-need t-to cum...w-want to cum~" He could see the image of the boos in his mind clearly now as he closed his eyes briefly; feeling their hands caress over his more slender form, feeling them raise his chin to meet their eyes as more drenched slit continued to drool to the floor below. He knew he couldn't resist, knew he couldn't fight as their will pushed even harder against his own - their teasing words forming a chorus in his mind that burrowed so deep that it echoed through every thought.

"It'll feel so much better with me in control~"

"Need to submit to us~"

"Need to give us your body~"

"Y-yes, I-I submit~! I submit~! P-please let me c-c--" Asriel whimpered as the words left his lips - the hold on his mind loosening as soon as they reached his own ears. He'd almost choke on the pleasure that followed as his eyes rolled into the back of his head, tongue lolling out as he felt his womb flooded with seed, his body convulsing as he finally was able to climax - even more juices drenching the ancient dry wood below. "Cumming~! O-oh f-fuck~ W-we're cumming~!"

With each burst of pleasure and spurt of cum Asriel's will would fade away that much more, gobbled up as those sharp teeth made short work of the now malleable soul that formerly inhabited that body. He could already feel his body fade away, his thoughts falling soon after as only pleasure remained as the last blinding pink light he could see. It would take minutes as those ethereal balls emptied within him, minutes as the last few changes to his body took hold before it would finally before - eyes rolling back into place with a now pinkish hue to the still present red; a crazed grin spreading across his face as he rose to his feet.

"Finally...a body." The new being would cackle as she raised a hand; pink light pouring forth to bathe her in its warm magical essence. A black dress would slowly cover her body, high heeled boots following, darkened gothic lip-balm and magic up finishing the attire as black threads streaked down her hair. If any part of Asriel remained he wouldn't be able to recognize what his body had become now - hips swaying with each step as she made her way from the mansion, the light of the full moon reflecting off of her glimmering eyes. "Finally free~"
