“This is the last time Trixie does an act without real practice!”  The disgruntled performance pony trotted hastily across town, her purple cape draped over her body as the moonlight illuminated her way.  Her eyes darted to and fro, avoiding familiar faces trotting about at this time of night.  Taking care to not trip over herself, she glances beneath her cloth.  She sported a fairly large paunch that jiggled with each step.  Even as she stood still, her oval belly would twitch and wobble as the outline of a hoof presses out from within.  A live pony was lodged deep within Trixie's privates from her latest trick, and her body refused to free the participant.  
 
        As she stared at the lumpy girth inside her womb, Trixie whispers to her underside.  “Listen, if you can stay still, we can get out of this sooner, I just need to find a secluded spot to let you out.”  Her wagon was out of the question, as the ponies were stunned by her latest feat.  Even the smallest interruption or knock on her living quarters made Trixie clench in a panic, throwing the pony back deep within her.  Admittedly, even Trixie's performance impressed herself as her nimble body and dexterous movements flowed over the pony.  While she practiced in private with medicine balls and other large objects, the thrill and excitement of a live, warm body was unmatched.  The scene plays before her eyes as she thinks back on her great and amazing accomplishment.
 
        “Behold, my final trick of the night!”  Lights flashed from the stage and fireworks lit up the starry sky as ponies stamped their hooves on the grassy ground, yearning for more.  Faint images of the Grand Ballroom in Canterlot played behind her as the illusion slowly faded into the deep blue night.  Her tricks have been refined and not only have the residents of Ponyville have forgiven her, but they enjoyed her presence.  Cleaning up her act literally and figuratively earned her the trust of this small town and even formed friendships with some of the ponies.  Though she was a traveling performer at heart, she can always come back here for a welcoming audience.  
 
        “I will need a pony from the audience, one of my choosing and of willing mind!”  Hooves shoot up into the air, waving eagerly for a chance to experience her craft.  Scanning the audience, she spots a familiar earth pony.  Nurse Redheart, her sapphire blue eyes glowed eagerly as her snow white coat  shimmered brilliantly in the light show.  Her pale pink mane, normally folded neatly in a bun flowed gracefully across her withers as she called out to Trixie among the masses.  Familiar with her open-minded spirit and enthusiasm for a pony's body, Trixie levitates the eager pony to the grassy floor below her.  Trixie hops off the stage, joining her friend on the ground level.
 
        “Now, watch as I make this pony... disappear!”  The crowd watches as Trixie motions to the area around her.  “As you can see, Trixie is on normal ground.  No trapdoors, nothing!”  She levitates a blindfold to her volunteer.  She quickly ties it around the nurse's eyes as she peeks above the strip of cloth.  “Now now, can't have Trixie revealing her tricks, now can she?”  As Redheart gives her an affirming nod, she pushes the blindfold back up.  Trixie leans close to the earth pony as she whispers into her ear.  “Might want to keep your chin up, will make the trick easier for Trixie.”  She obeys, taking on a stiff posture.  Trixie giggles mischievously as she looks back to the awaiting ponies.
 
        A distant drumroll silences the crowd as Trixie lifts a large curtain, patterned like her cape.  It surrounds the two ponies as it blocks all line of sight from the prying eyes.  The drumroll intensifies in volume as seconds tick by.  A brief moment of confidence and excitement loosens up her lower passages as it oozes with viscous honey.  Leaping into the air, she spreads her legs apart as anticipation drips from her lower half.  She lands directly on the snout of Redheart, who's rigid stance was broken by the sudden, hot sensation spreading over her face.  It was too late for her to react as Trixie's genital lips slipped cleanly over the head of the baffled pony.  The crown of Redheart pressed against the entrance of Trixie's womb, as the magician relaxed her maternal muscles.  The entrance to the padded chambers yawned open as Trixie's hips gyrated on her close friend, welcoming the pony to her depths.
 
        In a panic, the nurse rears back on her hind legs with her front hooves flailing about.  Trixie saw this opportunity as she rode the rearing equine.  Trixie's head popped up over the curtain as she winks to the crowd.  Their cheers gave her the white noise to clear her mind.  In one fell swoop, she stretched out her ridged canal as she sat down onto Redheart with all her weight and magic.  A juicy, squelching sound is barely drowned out by the rising sound of the drums as Trixie's rump hits the ground with a moist splat.  The pony's body is forced to curl up as the womb locks her inside, the fleshy entrance sealed tightly beneath her.  Though her thick, pink tail stuck out between Trixie's legs, she soon remedied that.  Using the last bits of her energy, she forces the entrance of her womb open as she hastily shoves the rest of the nurse's tail into the needy chamber.  The magician stands up on all fours with a smug look of satisfaction as her belly hangs low to the grass.  
 
        She looks over herself as she feels her entire lower region slowly shrink back to normal.  The once gaping lips of her groin tucked itself neatly between her plush cheeks, and the widened pink passage tightened until it could barely fit a pony's dock.  Her womb also started to retreat beneath the cozy fat of the blue unicorn, adding to the round girth of her belly.  While an entire pony resided within her uterus, Trixie has trained her body to hide away such large and heavy objects.  Though this is the first time she has attempted this on a pony, she didn't think it would be much different.  As she drops the curtains, only Trixie remained, as the drumroll stopped with a clash of symbals.  One last light show erupts from behind her as the crowd cheers for another successful performance.
 
        Trixie trots back onto the stage, cape draped over her back.  She bows as she takes her leave, the stage magically folding back into her traveling wagon.  Fireworks and spotlights continue to light up the sky as the magician retires to the sanctuary of her home.  While the colors of her personal cape were quite thinning on her form, her middle was significantly larger than usual.  Her sides bulged ever so slightly out as her belly hung inches lower.  Trixie's vaginal lips sloppily spat out excess gas to get a tighter grip on the pony, but it was not enough to truly hide such a large mass inside of her.  Feeling Redheart tap at the exit of her womb, Trixie let's out a plaintive sigh.
 
        “Trixie will let you out, do not fret dear.”  As she breathes to relax, the loud chatter outside her wagon become erratic.  No longer a steady volume, she hears ponies shout in excitement over the steady murmur of the crowd.  Each unexpected squeal of glee caused Trixie's loins to seize up, returning the passenger to her muggy depths.  The occasional pop and boom of the post-show fireworks did not help either.  Her practices did not include her concentration being broken frequently.  “Ugh!  Trixie cannot focus in these conditions.  We must flee to a more relaxing environment.”  Redheart wiggles in agreement, causing Trixie freezes in her steps.  She gives a labored sigh as the pony's movements sent a shock of pleasure up her spine.  With her magic and stamina completely exhausted, her body welcomed this new sensation.  Shivering at the startling source of satisfaction, Trixie shakes the thoughts of indulgement from her head.  “I know where we can go, follow- err... hold on.”  Trixie slips out beneath the her wagon, among the chaos of the ponies outside.
 
        Snapping back to the present time, Trixie finds herself in front of her favorite building in all of Ponyville: the Day Spa.  While it is already night, Lotus Blossom and Aloe have generously offered all hours access to Trixie for helping to publicize their spa.  Now a tourist attraction, it is normally closed during the sunlit hours.  But at night, it was the perfect escape for the performer.  Unlocking the front doors, Trixie prepares her usual fare.  The jacuzzi bubbles to life as the private room lights up with a dim, sensual atmosphere .  Closing the door behind her, she leaves her cape hanging on the designated hook.  Slipping into the warm water hind hooves first, she breathes a sigh of relief.
 
        “Yes... Trixie can relax to this...”  Stroking her enlarged middle, she feels her muscles slowly melt at the low vibration of the jacuzzi.  Bubbles caress her body as she feels pockets of air escape her lower lips, adding to the orchestra of bubbles popping on the surface.  She massages the plump middle with circular strokes, kneading her body into a softer state.  Her heartbeat slows as she feels the trapped pony shift uncomfortably in the claustrophobic enclosure, the slippery walls played with her as they closed in on the prone form.  While she trained her body to hide such large masses, the squirms of live ponies tickled her fancy in more ways than one.  Unfortunately, she had to let this volunteer out for now.
 
        Feeling her peace of mind returning, her occupied womb slowly slips out from underneath the padded fat surrounding her stomach.  As Redheart's form pops back into view from beneath her skin, Trixie's lower belly grows in size as it releases its practiced grip from within.  As her friend's outline comes back into view, Trixie sits up on the edge of the jacuzzi, her puffy genitals hovering over the bubbly water.  Her lower lips unfurl open as it pours her vaginal secretions into the bubbly liquid below.  The oily substance flows freely from her flower as she moans in ecstasy.  Taking shallow breaths, Trixie pumps her body up and down against her hoof.
 
        Pushing down on the pony-sized lump on her belly, Trixie begins to loosen her lower half once again.  Her hoof fondles her little bump until she feels the elasticity of her body slowly return.  Once circling the entrance of her pulsating tunnel, her fore hoof now fit snugly inside the pink depths.  She thrusts forward into herself, feeling her walls expand with each push.  Heartbeat pounding in her head, Trixie eyes roll to the back of her head as her womb's entrance starts to dilate.  The thick, muscular chamber coax the slick pony towards the loosened exit.  Trixie feels the rounded shape of her guest's head ease into her fleshy passageway.  She grunts as the rounded lump slowly approaches the center of her flower.  As she slips further out, Trixie sees the familiar white muzzle peek out of her gaping slit.
 
        “N-n-nice of you, t-to join Trixie...”  Trixie's breath shakes as she talks, clearly occupied with evicting her friend from her innards.  Nurse Redheart only gasps in response, breathing in the therapeutic sauna air.  Clearly an improvement from the humid atmosphere within Trixie's body, her head slowly slips out as her chin lightly taps the water below.  The dribbling mouth of the magician's crotch continued to pour a steady stream of natural lubrication into the jacuzzi as it struggled to push out its resident.  The medical pony's mane stuck flat against her head as white strings of Trixie's secretions glittered on her coat.  Her shoulders and forelegs were next to follow, all escaping with the distinct sound of slippery, wet flesh against itself.  Any remnants of trapped gas spewed out from between her legs, sputtering loudly against Redheart's soaked body.  
 
        Nurse Redheart slowly regains her senses as she dips her head into the odd mixture that bubbled below her.  Shaking off the water from her face, she looks around the room.  The steamy atmosphere clears her lungs as she rubs the drowsiness and fatigue from her eyes.  Looking behind her, Trixie continues to grunt in effort and pleasure as more of her body slips out.  Redheart attempts to help make her escape by pushing against the ground with her free hooves.  Her hasty push was met with a yank back towards the drooling darkness.  Trixie sharply inhales as she maintains her concentration.
 
        “Please, let Trixie do it... her body likes to keep everything close...”  With that, she lets loose a contented sigh as her body releases its grip on the mare.  Redheart's round belly slowly travels out of the vaginal canal as the round bulge slowly creeps out from under Trixie's own middle.  Trixie stutters in a blind state of euphoria as the soft pony torso slips out with minimal trouble, leading the way for the rest of her body.  The hind legs slip out soon after as Redheart dunks her entire form into the thick mixture below.  Shaking her coat underneath the water, Trixie focuses on recovering from the ordeal.  The gaping maw of her crotch slowly recedes back between her legs.  Once able to fit a pony, it slowly folds in on itself until it is nothing but a thin line that hid her life-giving organs.  Trixie's stomach goes back to a chubby oval from the lumpy mess it was when containing her guest.  She massages her belly, feeling her insides gradually shift back.
 
        “So... I'm assuming this was part of the trick?”  Nurse Redheart meets Trixie's eyes with a sultry glance.  Trixie blushes in embarrassment as she tries to find the words to respond with.  “While I would love to study the intricacies of your body at a later date, shouldn't we be back on stage with me reappearing?”  This obvious realization struck Trixie as she shakily gets back up on her legs.  Still worn from birthing her friend, she grabs her slimy friend in a hoof in a panic.
 
        “That's why there was such a commotion outside!  Come, Trixie must resolve this misunderstanding!”  As the two mares waddle weakly out of the spa, they move towards the large congregation of ponies, eagerly awaiting the return of their beloved magician and medical caretaker.
