            Alone in a room at an inn, Fern was starting to get nervous. The purple haired, young woman tried to keep herself occupied by tapping her fingers against her staff or getting rid of the wrinkles on her black coat and white gown. Typically, the thought of her master staying out late by herself was settled by the knowledge that the elf was one of the strongest mages in existence. However, she couldn’t shake off a sense of dread that hung on her shoulders like the weight of a horse.

            Fern’s introspection as to why she was feeling this way was interrupted as the door to the room swung open. Though she couldn’t see who it was at first, the large stack of random bottles and boxes blocking her view gave her a good clue. Dropping off the haul of items on the ground, the elf with twin-tails of silver hair greeted her apprentice with a wide grin.

            “Where have you been?” Fern asked as Frieren brushed off any dust from her white skirt and blouse.

            “This town has a very interesting collection of magic shops,” the elf replied, her voice muted but still managing to express her excitement with the look in her eyes. “I managed to get all of this for just a few gold coins.”

            “And that wasn’t suspicious?” Fern asked, seeing the pair of pointed ears sway back and forth as the elf rummaged through one of the boxes.

            “That’s the fun part,” Frieren replied as she popped her head back out. “More than likely there will be some duds mixed in, but something of actual value might have been included. We get the privilege of figuring out which items are genuine.” Standing back up, she held up a bottle containing a bubbling pink liquid. “For instance, take this potion. It’s supposed to be able to let a person experience other worldly pleasure.”

            Fern raised an eyebrow at the strange mixture. “What does that mean?”

            Pausing for a moment, Frieren scratched at her chin. “I’m not entirely sure. The only other thing on the label is the conditions for the effects to be negated. I’ll be sure to give it a thorough examination before trying it out. We can get started since we have some time before Stark meets up with us for dinner. I think I have a tool in my bag that should help us-“

            Too excited by the premise of discovery, Frieren failed to notice one of the other bottles roll out in front of her. Tripping over the object, she managed to stop herself from falling, but the potion wasn’t so lucky. Unable to move fast enough, the pair of women could only watch as the pink liquid twirled through the air. When the container finally smashed against the ground, it showered the women with the mysterious, pink liquid.

             “That was unfortunate,” Frieren commented, trying and failing to brush off the mess from her clothes. With a shrug, she stood up to meet face to face with her apprentice’s typical pout.

           “Miss Frieren, I urge you to be more careful,” Fern reprimanded as if she were the elf’s mother. “Especially with potions we know little to nothing about.”

           “Of course, of course,” Frieren stated as she wiped the lingering drops of potion off her face. “At least the other bottle didn’t break. I think it rolled underneath the bed.”

           “You wouldn’t have tripped over it if you hadn’t brought so much junk into our room,” Fern replied with an even stronger glare.

           Frieren meekly lowered her head to avoid Fern’s gaze, letting out a sigh as she looked at the shattered glass on the floor. She was sad to have wasted the potion like that. Even still, she could sense that whatever the liquid was meant to do, she could feel the first signs show up in the form of the strange tingling going across her body. Rather than distress at the warmth permeating across her skin, her curious grin appeared once more.

           “Do you feel any different?” the experienced mage asked, fanning herself with her hand. “Anything notable?”

           “Now that you mention it, my clothes feel a lot tighter than before,” Fern noted, tugging at the collar of her gown as she experienced the same prickles of heat along her body.

           What started out as a slight discomfort mutated into something else as the tingling focused on specific parts of Fern. Specifically, it was as if sets of invisible hands were rubbing against her chest, backside, and in between her legs. In an effort to deal with the rising heat, she shed off her coat and watched as her master did the same.

           “It seems our bodies are changing,” Frieren mused as she removed her outer robes. “These types of potions are always interesting with how unique their effects can be.”

           Fern turned to Frieren to ponder how many times her master had done something this, only to see the elf’s previously flat chest slowly rise. Though she felt the same sensation going across her own bosom, her focus drifted towards the tightness affecting her panties as her buttocks began to swell. Lifting up her skirt to fully understand what was going on, she revealed something pushing up against the front of her panties.

           Pulling the undergarment aside, Fern let out a yelp as she spotted the dick jutting out from her groin. Feeling her new manhood’s testicles jostle against her vagina, she once more looked towards her master for assistance. What she witnessed was a similarly imposing cock and balls growing out from beneath Frieren’s skirt to obscure her womanhood. As Fern stared at the dicks growing between their legs, a rush of emotions flowed through her. Anger, surprise, curiosity, and a growing flame of lust.

           “This is too much to process,” Fern said, mainly to herself. A shaky hand hovered above the growth, unsure of her next step. “We should find a way to counteract whatever was in that potion you spilled on us,” she spoke to herself as she struggled against the curious desire to rub her new manhood. “What do you think, Miss Frieren?”

           The only response Fern heard back was the sound of heavy breathing. Turning away from her rigid member, she watched as Frieren slowly slid her fingers along the length of her own cock. As the first drag of her palm across the shaft brought forth droplets of cum from the tip, the elf pushed herself to rub back and forth. While the purple haired woman found the increasing speed of her master’s masturbation session revolting at first, she couldn’t stop herself from watching.

           More droplets of cum trickling out from the elf’s tip ate away at what little restraint Fern had. Staring back at her own, needy cock, she saw the same liquid starting to seep out. The sight mixed with the sound of Frieren’s moans made her body tremble. Try as she might to resist the urges that flooded out from her groin, it hit a point where a voice inside of her head asked, “What would be the harm in just giving it a touch?”

           The experimental taps of Fern’s fingers against her shaft turned into a tight grasp as she felt the first tremor of pleasure. Copying her master’s actions, she began to vigorously pump up and down. Leaving her mouth open, she freely let the hot breath of her moans blow onto her throbbing cock. Whenever she bothered to break her gaze away from her masturbation session, it was to see Frieren moving alongside her on the same journey to experience every ounce of pleasure that their new additions provided.

           Feeling her new testicles shudder, Fern ended up being the first to shoot out her load. The wad of cum was flung upwards to further stain her clothes. Leaning back on the bed, she watched as Frieren made a similar mess on her own body as she experienced her orgasm. Her mind a mess of hormones and questions, Fern tried to catch her breath in the hopes of figuring out what their next step would be. Unfortunately, she was cut short by the vibrating sensation emanating out from her breasts and buttocks.

           Tired of them getting in the way of her overwhelming lust, Frieren stripped off the rest of her clothes. A perverted look crossed the elf’s face as she grasped her growing breasts and vigorously massaged them. Barely able to reach the peak of her nipples, she let out a hiss of pleasure as she pressed her fingers into her teats. The frantic stimulation was more than enough to make her member grow rigid again. However, she was more concerned at the moment about giving attention to her newly engorged bosom.

           “This must be why men seem to love them so much,” Frieren commented as she gave her stiffened nipples a pinch.

           Across the room, Fern bit her lip as she felt her growth spurt focus on a specific part of her body. Her skirt grew taut as her ass cheeks swelled to take up more of her bed. In the process of trying to make herself comfortable, she shrugged off what remained of her clothes to leave her completely nude. Ignoring her own enhanced bosom for the moment, she reached out with the intention of removing her panties.

           “Leave them on,” the voice spoke up, making her fingers stay still in spite of the growing tightness of her undergarment. “Let your ass swallow them up.”

           Fern’s hands glided across her growing globes, occasionally squeezing the masses as her panties dug deeper into her cheeks. She slipped a hand between them to dig out her panties when her fingers brushed over her asshole. A small moan escaped her lips while her cock twitched to attention. Unable to hold back her curiosity about this reaction, she began circling the rim before plunging a finger into her hole.

           The young woman’s pace started slow as she got used to the unexplored stimulation. Once she felt comfortable enough to speed up the process, moans began to leave her lips. When her hole became too loose for a single finger to satisfy, she didn’t have any hesitation to slip in a second one. Reduced to a whimpering mess thanks to her first session of anal masturbation, her other hand grabbed onto her cock. She soon built a rhythm between pumping her throbbing member and shoving her fingers in and out of her asshole. Reaching her limit, she cried out in ecstasy as she sprayed her seed all over the floor.

           Recovering from orgasm, Fern’s attention turned to other needs. Rather than cleaning up the mess, getting new clothes, or trying to reverse the effects of the potion, she kept smacking her dry lips. In the process of trying to wet her mouth with her tongue, she collected a stray drop of her own cum. The strange, yet bizarre flavor gave her body an inkling of what it needed to be satisfied.

           Fern’s initial idea to merely use her own supply was hindered by most of her cum having leaked onto the floor. Before she could attempt to lick up the remnants, her attention turned towards Frieren. Still busy playing around with her own, enhanced assets, the elf had left her cock to its own devices. With each throb going through the meaty members, a few droplets of semen managed to spill out. Unwilling to let such a delicious meal go to waste, Fern decided to take matters into her own hands.

           Getting down on her knees, Fern surged through any feelings of shame as she placed her mouth on the tip of Frieren’s cock. Though she was eager to slurp up what she could, she faced immediate problems as she realized just how large the shaft was. Try as she might to get down as far as possible, the most she could handle were a few inches before she hit her limit. Undeterred and unable to contain her desire, she bobbed her head back and forth to make the most out of what she could muster.

           The blowjob became easier for Fern as her neck became stretched out and thickened up. The grip her mouth held on the cock grew tighter as her mouth reformed itself into an o-shape. Freiren showed off her fondness for the purple-haired woman’s plumper lips as she began to let out a series of moans. With her tongue growing longer to facilitate sliding across the entire length of the shaft, Fern was eventually able to get what she desired as her mouth was filled with a load of the elf’s cum.

           The apprentice’s enthusiastic drinking finally managed to pull Frieren’s attention away from her beloved breasts. She watched with a sultry smile as Fern’s neck elongated even further; gaining extra mass to match the thicker appearance of her torso. She bit back her moans as Fern seemed to learn on the fly how to give a better blowjob, the movement of her head and tongue changing with each bob.

           It didn’t take long for Frieren to cum inside Fern’s mouth again. The second helping chugged its way down the girthy throat without a single drop being spilled. The experienced mage gasped as her apprentice kept sucking in an effort get more out of the over foot and a half long cock. In turn, the elf’s testicles became further engorged to meet the demand of her needy partner.

           Enduring the hungry mouth of Fern, Frieren reached forward with her hands in an effort to stabilize herself. She was forced to stop as her fingers hardened over each other, forming one large nail. Her arms grew thicker to match the new transformation, as well as give her a chance to press her “hands” together to confirm what they had become.

           “Hooves, how intriguing,” the elf muttered as she watched her feet go through the same transformation.

           The act of the mage trying to stand up on her newly hooved feet caused Fern to come up for air. Frieren only managed to stumble around for a few moments before her modified limbs and spine forced her down to the ground. Any sense of innocence brought about her moving like newborn foal learning its footing was undone by the sight of her two foot-long cock dangling between her legs.

           With each one of Frieren’s awkward steps, more of her face distended outwards to mimic that of her apprentice’s. The puffier lips adorning her ring-shaped mouth beckoned for some form of moisture. Trying and failing to fulfill her needs by running her elongated tongue along her modified lips, she was forced to turn her thick neck elsewhere for relief. What her horse-like head led her to focus on was the plethora of cum still hanging on Fern’s face.

           Given a much needed rush of energy to work through her less than graceful movement, the elf managed to stomp her way over to the purple haired woman. A pleased moan was shared amongst the two of them as Frieren came in for a kiss. Though she couldn’t grab onto her partner’s assets, the sheer stimulation brought about by the sloppy twitches of her tongue was enough to make Fern give in to the embrace.

           Under the duress of her master pushing against her, Fern was forced to get down on all fours. Stability was gifted to her in the form of her hands and feet becoming more hoof-like as well. The added strength provided to her thicker limbs and torso were invaluable for keeping her in place as Frieren continued the messy make out session. By the time the two finally parted with a trail of saliva connecting their two mouths, they had both changed to resemble a pair of fleshy, depraved horses. Simultaneously, the two heard in their heads the voice speak the word: DORSE.

           Frieren let out a content whinny as she shook her head, her pigtails falling free from their ties in the process. Whipping around her freed hair, the newly transformed dorse managed to make her locks resemble a mane. Putting aside the admiration she felt for the uniqueness of her body. She turned her attention towards Fern who seemed to be rubbing her ample posterior on one of the bedposts.

           With a newfound confidence, Frieren sashayed, as much as her dorse body would allow, over to her apprentice’s rear. As she walked, a small nub formed at the tip of her spine that was eventually covered up by more silver follicles to form her tail. When she finally reached Fern, she saw her prize sitting in front of her. Nestled between other dorse’s large butt cheeks and curtained by a tail of purple hairs was her asshole, puckering with need. Angling her head back to face her master, Fern’s eyes pleaded for help satiating her libido.

            Frieren didn’t waste any time diving her tongue into her partner’s asshole. In spite of her body requesting the act, the purple haired dorse still let out a surprised neigh. Entranced by the sound, the elf lowered her face closer to press her lips against the orifice. Circling the rim with her tongue, Frieren shifted back and forth between her speeds in order to test the limits of what her apprentice could handle.

             Some part deep down in Frieren knew this was wrong. That she shouldn’t be doing these things with her apprentice. However, the potion’s effects had dulled that rational part of her brain until it couldn’t speak out anymore. All that was left was a mind unrestrained by dignity, similar to the sense of lustful desire that had already overtaken Fern’s thoughts.

            Letting out another equine moan, Fern let herself give into her orgasm. Frieren was barely able to hear the loud splat of cum along the floor as her face was nearly engulfed by her apprentice’s expanding butt cheeks. As she staggered backwards, the elf dorse noticed that some of the load had managed to make its way onto Fern’s tits. The sticky substance proved to be the perfect catalyst to further engorge the purple haired dorse’s bosom several sizes.

            The few inches separating Fern’s nipples form the floor disappeared as she roughly pressed down against the ground. Rolling her breasts back and forth along the floor, she let out a string of moans that spoke of the overflowing desire that had yet to be sated. If there was any confusion left on Frieren’s mind about what she was supposed to do next, it was taken care of by her apprentice clenching her ass cheeks along her cock. Stuck between the meaty mounds, the elf understood the full intent of her partner as her shaft was dragged back and forth across the pair of needy holes.

            Frieren reared up with all her strength and plunged her cock into her apprentice's dripping womanhood. Her boobs pressed against the other dorse’s back as she started thrusting in and out with the full force of her wide hips. Fern used her back legs to assist her master, trying to stay in rhythm with each jolt. The combined effort ensured that the room echoed with the sounds of their hooves stomping against the ground and the euphoric moans that came pouring from their puffy lips.

           The elf didn’t last long as she was still pent up from playing with her apprentice’s ass. She began to huff as she seemingly went faster and faster, as if she was in a deep haze. Adding in the sensation of her larger, more sensitive breasts rubbing together and the tightness of Fern’s pussy, the elf climaxed with a sizable load filling up her partner’s insides.

           It took Frieren a second to hoist herself off Fern, surveying her work with a look of satisfaction. Though her mind was a mess of lust, she could still notice the expression of wanting in the purple-haired dorse’s eyes. Her own cock still yearned for pleasure, but what little remained of her normal self told her that she needed to give her apprentice a chance to fully enjoy their new bodies.

           Sucking in the air to recover and revel in the smell of euphoria that permeated the room, Fern missed the sound of her master’s hooves clopping along the ground. She finally took notice of Frieren once the silver-haired dorse laid down on the floor in front of her. Rolling herself over, the elf spread out her limbs to give a full view of her body. Letting her gaze linger on her master’s sizable bosom and rigid cock Fern eventually drifted her eyes towards the puffy womanhood barely visible beneath Frieren’s swollen testicles.

           Understanding the generous gift that had been offered to her, the purple haired dorse wasted no time ramming her cock into her partner’s pussy. With each thrust, Fern had more of her body clamber against her master’s. While her own cock had originally been left bare, Frieren’s submission had granted her manhood the feeling of being embraced by her apprentice’s ample bosom.

           As the pair of dorses began to reach their limits, a powerful thrust left the two of them right on top of each other. The couple’s moans became muffled as their mouths were pressed together. Savoring their passion and unbridled lust, they allowed themselves to revel in the euphoria permeating across their forms. Even with their tongues intertwined, the eventual orgasms that shook their bodies forced them to separate. Rearing back, Fern inadvertently angled her master’s cock to shoot her load across their bodies. Rather than bemoan the mess their latest release had made, the beasts did their best to suck up the remains from their flesh.

           Once they finished cleaning off their own bodies, Fern and Frieren rolled off of one another to search through the room. Drinking up every drop of cum helped to gradually re-energize their stamina. As they reached the final spill, they managed to keep their urges back for the few seconds it took to take on the liquid meal. From there, the series of grunts they made as they pressed into each other once more made them ignorant to the sound of the door to their room creaking open.

           Stepping forward with a hand on his axe, Stark got ready to fight with the strange creatures. The momentary pause that came from him recognizing the similarities between the dorses and his companions came alongside him seeing the shattered remains of a bottle on the floor. Locating the label of the broken container, he relaxed the grip on his weapon as he got an idea of what happened. Letting out a sigh, he shut the door to the room of the inn and headed back downstairs. While the two mages worked through their lust together, he would spend the evening eating a good meal and trying to ignore the sounds of moans and clopping hooves.
