“It’s a shame we didn’t find anything of interest on this expedition professor.” The slightly rotund Morris Chutney made small talk with his adventuring partner as he flew their biplane. “Nothing but a sick prank by the locals that was!”

“You can say that again Morris.” Tenured archeology professor and world renown adventurer Emilia Atkinson responded. She looked out the plane's window at the eastern coast of South America, her hand cupping her cheek as she leaned into it. They had come down here to hopefully find some artifacts and ruins as there’d been reports of ancient figurines in the area. Well those ‘ancient figurines’ ended up being some art pieces which the locals told a tourist were ancient and rare to jip them out of more money. But it worked, they even managed to waste a good chunk of Emilia’s and Morris’s time. Morris banked the plane and as they were turning Emilia made out some land out in the horizon that shouldn’t have been there. “Wait Morris! Look!” She tapped him on the shoulder and pointed out at sea. “There shouldn’t be any islands there, at least not according to my map.”

Morris leaned back and followed where Emilia’s finger was pointing. Indeed off in the horizon was land which had been uncharted. “What a great find, Emilia! It looks like we aren’t going home completely empty handed.” Morris banked the plane once again and began flying towards the island.

Emilia got to work grabbing all of their belongings and packing them neatly into their bags for their impromptu expedition. Even if there weren't any archeology sites they’d make sure to chart out the perimeter of the island so they had something to bring back to the states. As they got closer to the island they could make out the tall trees and lush foliage of an undisturbed jungle with a small mountain poking its way through the canopy towards the far side of the island. “Can you spot anywhere safe enough to land?”

“Not yet Ms. Emilia, it’s too-” Without warning the propeller electronics in the plane shut off as the plane began to descend. Morris grabbed the stick and pulled it with all his might, trying to pull the nose of the plane up with the mechanical flaps but it just wasn’t enough. “ We’re gonna crash! Grab onto som-”

------------------------------

When Emilia came to, she found herself laying face first in a patch of dirt. Her ears rang as small isolated bits of fire crackled about. A sheet of metal from the plan had landed on top of her, luckily just bruising her but she was pinned by its weight. Hers and Morris’s belongings were scattered across the crash site along with wood planks and shreds of woven leaves… “Morris!” Her eyes darted about the wreckage looking for any sign of her friend. He wasn’t out among the wreckage like she was and the cockpit of their biplane was crushed into the ground with what looked like a bell dropped on top of it. She rolled over as much as was able to and tried to push the sheet of metal off of her to no avail. It was simply too heavy for her. “Come on! Why- won’t- you- budge!”

“Do you need help with that?”

“Holy fuck!” Emilia was startled by the deep voice that suddenly spoke up from behind. She turned and felt the blood drain from her face as she went pale at what she saw. A large gorilla standing upright on it’s hind legs and wearing rudimentary clothing had somehow snuck up on her and was now looking right at her.

The gorilla cleared its throat, “I’ll ask again. Do you need help?”

Emilia silently nodded at the gorilla, still unsure if what she was seeing was real. The gorilla nodded back before taking a few steps towards her and lifting the sheet of metal off of her. She crawled out from beneath the metal sheet and turned back to watch the gorilla drop the heavy metal back onto the ground. “Uh… th- thank you for rescuing me!”

“It’s no problem.” The gorilla turned and gestured at the trees, waving them to come in. A couple dozen monkeys and apes, each dressed in a wide range of simple fiber and plant based clothes made their presence known as they approached the crash site. The apes began clearing away the scraps of rubble as the monkeys carried wooden buckets full of water to stamp out any rogue fires. “Please follow me.” 

The gorilla began to turn but Emilia spoke up. “Wait! My friend is still in there!” She pointed towards the cockpit of the plane.

The Gorilla stopped and looked at where Emilia was pointing before slowly shaking his head. “We will bury him and you’ll get to pay your respects but we must make haste.”

Emilia bit her tongue and silently followed the Gorilla. It wasn’t her first time dealing native tribes even if this one was made up of speaking monkeys and apes. And although they seemed friendly the Gorilla seemed in a hurry and she didn’t want to push her luck. After trekking through the jungle for a while they came across a large clearing that opened up to a large lake at the base of the mountain. Surrounding the lake was a robust village of anthropomorphic gorillas and monkeys going about their day. Stalls lined the wooden walkways where freshly caught fish and ripe harvested fruit were being sold. Children danced through the crowd's feet as they chased and played with one another. Who would’ve thought hidden away on this island existed a civilization of intelligent apes?

Despite her gawking she followed the ape man around the lake and through various districts of the village. From the lake side market district, past an agricultural district, and through a residential area until they reach the mountain where in front of a gorgeous waterfall, atop a flight of wooden stairs sat a hut with smoke billowing from a hatch on the roof. She was led up the stairs and to the front of the hut where the gorilla man knocked on the door. “Sakiko needs a favor from you and I must go. He is a very nice man.” As the door to the hut opened he left back down the stairs they just came from. 

Emilia entered the hut. It was one large room which had been separated into different segments. Along one wall there hung a hammock among some instruments and painted canvases while on the opposite side, underneath the hatch in the roof, was a large cauldron with shelves and tables full of herbs, dried fruits, and jarred insects. Behind the cauldron, sitting on a stool was an orangutan man who was wearing something akin to a robe and an intricate headdress. With his feet he holds a large ladle which he uses to stir the contents of the cauldron while with his hands he reads from a large leather bound book and periodically drops in more ingredients.

“Excuse me, are you Sakiko?”

“Hmm?” The orangutan man lowered his book and peered over it. “Oh! You’re here already, that’s wonderful!” He rested the ladle on the side of the cauldron and set the book face down on a nearby table as he jumped down from his stool and approached Emilia with one arm extended to shake her hand. “I am Shaman Elder Sakiko but the title isn’t necessary.”

“It’s nice to meet you Sakiko.” Emilia reached her hand out and met his, giving him an awkward hand shake. “My name is Emilia.”

Sakiko nodded in acknowledgment before leading Emilia by her hand closer to the cauldron. “I luckily just got everything finished Emilia so I’d appreciate it if you hear me out.”

“I still don’t really know what’s going on so… sure!”

Sakiko jumped back onto his stool and patted the seat of a chair next to him. “Take a seat and I’ll get started.”

Emilia sat down next to Sakiko and listened to him as he gave a brief lesson about the island's history. He explained that the mountain nearby was rich in a magnetic metal that scrambled any and all electronics. In fact, she wasn’t the first person to even come to the island by accident but because of the mountain it was impossible to leave. “Now,” Sakiko explained, “one of my jobs as Shaman Elder is to help you get acclimated to our way of life and to assign you a job.” He grabbed a wooden bowl from the table and ladled some of the cauldron's contents into it. “Now normally I would discuss with you what jobs best suit your wants and skill sets but I’m in dire need of someone filling a role before sunset today.” 

Sakiko handed the bowl over to Emilia which was filled with a thick, yellowish-white liquid that had a sweet aroma to it. “You want me to drink this?”

“It is custom.” Sakiko nodded his head.

Emilia hesitated, looking down at the not so appetizing mixture she had been handed. “Okay…” She lifted the bowl to her lips and slurped down the contents which she found surprisingly pleasant. Despite having a strange salty taste it mostly tasted of fresh coconut and pineapple. She smacked her lips and set the empty bowl down. “So is that symbolic or-?” An intense heat suddenly washed over her body telling her that ‘No, it wasn’t just symbolic.’ Sweat began to form across her skin as she fidgeted in her seat. The warmth inside her was uncomfortable as every touch or movement across her skin tingled with pleasure. All across her body patches of fur, brown like her hair, began to sprout up like weeds in a garden until most of her face, limbs, and face was covered. Her ears felt swollen as they grew in size, changing from a human ear to large rounded ones akin to a chimpanzee. Her feet quickly filled her shoes as they too changed, eventually bursting free from her boots. She wiggled her toes, finding that she had much better control over them now that they were prehensile feet. On her back at the base of her waist her spine began to elongate as a long and thin, fur covered tail began to grow. 

The strangest sensation amongst her chaotic changes was the pulsing and unbearably pleasant heat centered on her hips and rear. Each rhythmic pulse of radiant heat caused her fur covered ass to jump in size. Her thighs became as thick as tree trunks as they bumped into one another. Her hips jutted out, getting caught on the armrests of her wooden chair. Ass flesh spilled over her chair as her butt fought against its makeshift constraints until- Wood cracked and splintered beneath Emilia as her preposterous posterior won the battle against the chair sending her plummeting ass first into the ground. Her wobbling soft meat cushioned her fall with the sound of a faint reverberating drum beat. With a lot of effort Emilia used the table to brace herself and get back to her feet. “What was in that stuff!?” She rubbed her ass as, although it absorbed a lot of her fall, the direct area that landed on the floor was sore.

“Nothing I normally don’t put in there.” Sakiko scratched his head as he picked up his book and skimmed through it. “Maybe it’s because…” he muttered before closing the book and turning his attention back to Emilia. “Do you know how to play an instrument?” He asked and watched as she shook her head. “That’s interesting! May I try something?”

“Uhh… sure? I guess?” Emilia stood still, her cheeks a vibrant red from the embarrassing situation she found herself in, as Sakiko got behind her. Without warning he lightly spanked her rear causing it to ripple. Instead of hearing light smacking noise her butt instead made a hollow reverberating noise similar to a wooden drum.

“I think I know what happened.” Sakiko walked back in front of Emilia and began explaining his hypothesis. “The potion you just drank does two things. The main effect is that it alters your body to that of a primate to help you better acclimate to your life on the island. The second effect it has is it will change your body to better suit the job you have chosen and… well it’s strange but it’s given you just that. You see, your plane crashed into our bell tower which we ring everyday before sunset so those who are outside of the village know to start returning before the predators start their hunt. Without our bell tower and with you not knowing how to play an instrument it… well it made you into an instrument.”

“This is all a lot to take in.” Emilia rubbed the bridge of her nose. “Like I can accept talking monkeys and even being a monkey but this?” She twisted her hips, pointing her comically large rear at Sakiko. “I can’t live with this!”

“Please, just do this until we can rebuild the bell tower! If you don't, a lot of people may get hurt or even killed. Especially those out today, they have no way of knowing that the tower was destroyed.”

Emilia’s mind was racing as she stood awkwardly silent in front of Sakiko. She somehow felt more nude with just her shirt on than if she was just nude and she was being asked to fill an urgent task. Emilia was really only in this for archeology and found herself out of her depths. If only Morris was here, he was always good at winning over people. She sighed, “Morris would have wanted to help. I’ll do it but we need to deal with this,” she gestures to her waist and hips, “once the bell tower is fixed.”

“Thank you so much Emilia! Once the tower is fixed you have my word that we’ll discuss a new role for you and take another go with my potion.” He seemed elated and relieved to hear that Emilia was willing to help as he vigorously shook her hand. “Now we’re still in quite a predicament however. Our old tower is deep in the jungle and I don’t think it’d be safe to send you in alone. Plus we still need someone to…” His voice trailed off before he snapped his fingers, “Ah-hah! I have an idea!” He turned towards the back of the hut and cupped his hands around his mouth shouting, “Moroto! Can you come in please? I have something to ask of you!”

A well hidden door along the back of Sakiko’s hut creaked open as a towering visage made its presence known. Stepping through the doorway, having to duck his head and shift his shoulders to fit through, was an absolute beefcake of a primate man. The silver and black furred man towered over Emilia and Sakiko as the top of his head came just a few inches shy of hitting the ceiling. Morot wore just a loincloth made of rugged burlap which put both his muscles and ill-covered dong on display. Swinging freely between his legs was what Emilia could only describe as a truly monstrous cock. It was nearly as big as she was, minus her exaggerated rear, and adorned with two swollen testicles each the size of coconuts.

“Emilia, this is Moroto. He usually acts as my personal guard but for now I’m gonna have him escort and protect you while you’re out in the jungle.”

“It’s uh… nice to meet you Moroto.” Emilia's face was bright red. She was already embarrassed about being bottomless but now, no matter how hard she tried, she couldn’t get her eyes off of Moroto’s hog sized penis or his barrel sized pecs. 

Moroto simply nodded in acknowledgment towards Emilia before turning to Sakiko. “We should leave now. It’s almost sunset.”

Sakiko once again thanked Emilia as he hurried the two of them out the door. Moroto had Emilia walk ahead of him as he occasionally grunted out directions. “Left at junction.” “Right at sign.” “Right by mossy rock.” All the while as they made their way through the village and the jungle Emilia kept her red flushed cheeks. With her shifted center of mass she found that she had to adjust her gait which meant she had to sway and roll her hips as she walked which just brought more attention to her butt. On top of that each step she took caused her rear to wobble and shake which in turn meant the beating of drums followed her as her dumpy cheeks slapped against each other. Of course this meant that before they left the village's premises everyone’s attention was on her and that was still somehow less embarrassing than now. Her butt rhythmically rang out soft bongo claps as she and Moroto trekked through the quiet jungle with only Moroto's directions breaking up the passive sounds her body made.

“It should be just up ahead.” Moroto pointed past a small bend in the trail at the wooden tower. Its top rose above the treeline despite its run down appearance. The two made their way up to the tower's top where they were greeted with an open and bare room which had been overtaken with vines and dust. “Lay down on this mat.” Moroto cleared some dirt from an old bamboo mat and patted where he wanted Emilia to lay down.

Emilia nodded and gingerly walked up to the mat. She got down onto her knees before leaning forward and resting her stomach on the ground. Her ass jutted upwards from the rest of her body, still jiggling like a cube of jelly as she moved. Moroto followed shortly after, plopping down hard onto the ground behind Emilia. He sat with his legs splayed outwards around Emilia and leaned forward. He set each of his massive silverback gorilla hands onto Emilia’s ass cheeks and as he shifted forward his gorilla dong bumped into Emilia’s taint. Despite how massive Emilia’s booty now was, Moroto's hands were able to cover them completely.

“It’s almost sunset. Are you ready?”

“I- I guess…” Emilia couldn’t bring herself to look back at Moroto as she answered. Her anus twitched as his gorilla hands gently gripped her butt and his cock radiated heat which she could feel sat between her legs and just below her ass. Moroto lifted one hand from her rear, lifting it high above his head before slamming it back down into the make-shift drums in front of him. “Oh~!” Emilia tensed up as her ass was slapped with a beast like strength. The loud clap of a bongo rung through the jungle causing nearby flocks of birds to set off in flight. As soon as Moroto’s hand landed on Emilia’s rippling rear he lifted the other, alternating which cheek he’d beat in a musical rhythm. Emilia couldn’t help but squeal and mewl with every strike to her bottom. Her fur covered ass was numb with pain where sore, red hand imprints were left but each open palm strike to her cheeks sent vibrations through her core. Her innards tingled and her abdomen shook, tensing with each palpable bongo beat of her bouncing butt. The mat underneath her was soaked in juices which her monkey twat leaked profusely but before she could pass over the horizon and get her release Moroto suddenly stopped, leaving her panting and edged on the dusty floor.

“That should do it.” Moroto said with certainty in his voice as he stood up from the ground. He extended a hand down to Emilia to help her up.

“Thank you~” She cooed as she grabbed onto his hand. He effortlessly lifted her to her wobbly feet, letting her cling to his arm as support.

“We too should head back before sunset. Do you have a place to stay?”

“I ugh… no I don’t believe I do.”

Moroto’s cheeks and snout lost some stoic demeanor as a slight blush crept along his face. “You can stay with me for the night. We can talk to Sakiko tomorrow about finding you a place to stay.”

The two of them made their way back to the village as the sky turned a beautiful collage of purple and orange with the sun slowly setting beyond the horizon. They didn’t say much as they walked, just letting Emilia’s rear fill the silence with its drum noises. She hoped Moroto didn’t notice the trail she was leaving as her burning labia drooled moisture onto the jingle ground but he never made a comment on it as he followed behind her.

Moroto welcomed her into his abode, a small yet cozy hut which didn’t have much furnishings in it. He showed her where the bathroom and kitchen was before showing her where she’d be sleeping for the night, a queen sized bed which happened to be the only bed in his house. “This is where we will sleep.” He got underneath the covers and patted the other side of the bed.

“Oh! Do you uhh… have a different bed?”

“Why would I have two beds?”

“Yeah… I guess you’re right.” Emilia let out a nervous chuckle. It was already rather late and she didn’t want to burden Moroto with finding her somewhere else to stay but- Her face became flushed at the thought of sharing a bed with him. No! It was only for one night, she could do this! She climbed onto the bed and wiggled her way under the sheets.

Moroto quickly fell asleep once he closed his eyes, filling the room with his soft guttural snoring. Meanwhile Emilia was struggling to get any rest. Due to Moroto’s sheer size he took up about three quarters of the bed which meant Emilia was snuggled up nice and tight against him. This also meant that she could smell the pleasant and arousing musk emanating from his soft fur which combined with her lack of release from earlier was driving her nuts with arousal.

Moroto grumbled something in his sleep and rolled over onto his side, wrapping his large gorilla arm around Emilia who found herself as his new snuggle buddy. His meat had found itself sandwiched between Emilia’s buns. The heat from his dick was comforting and the sensation was too much for Emilia to ignore, she couldn’t help herself! When she eventually rattled her thoughts free from her bedmates anaconda she found that she had begun to unconsciously grind her cake into Moroto as his already massive while flaccid dick became engorged with blood. “Fuck~ I can’t help myself~!” She pushed back hard against Moroto, pinning his tree trunk of a dick between his waist and her rear.

“Hmm?” Moroto stirred from his sleep due to an unfamiliar bestial sound he had heard. His crotch and abdomen felt the warmth of someone else pushing against him. He lifted the covers to see Emilia grinding her spread cheeks on his penis, letting soft lust filled grunts and moans leave her lips. “You know,” Moroto held Emilia tightly to himself as he rolled over on top of her, “If you wanted it you could’ve asked.”

Emilia yelped as she was suddenly moved against her own volition, rolled over onto her stomach as Moroto pressed her against the mattress. “Hah~ I didn’t want to bother you~” 

Moroto chuckled, “I wouldn’t have minded.” He shifted his weight a bit, placing both of his hands on either side of Emilia’s head while pulling his waist back so his cock pointed down at her ass. He could easily crush the woman’s head with one hand yet he instead gently ran a finger through her soft and silky hair. Emilia wiggled her butt at Moroto, inviting him to his treasure of booty which he gladly accepted. He lowered his waist pushing the head of his cock into the star shaped hole which his plunder pillowed around. 

“Oh~!” Emilia gasped as she felt her anus slowly stretch around Moroto’s cock. He pushed his way inside gingerly allowing her to feel the full sensation of being stretched and filled. Her asshole suckled at the head of Moroto’s penis, slowly accommodating its size. The head eventually popped its way past her sphincter, leaving just the shaft free from its clutches. Moroto continued to invade Emilia’s anal cavity by pushing his shaft further inside her. Each throbbing vein on his cock uniquely pressed against her abused and stretched anus until- Emilia could feel the entirety of Moroto’s weight on her as his waist met her butt and his swollen testicles tested against the under part of her butt cheeks.

“You doing alright? I can feel you shaking.”

“Yesh~ Don’t shtop now~!”

“Okay,” Moroto chuckled and began unsheathing his cock from Emilia’s ass. He watched as her anus gripped onto the shaft of his penis, fruitlessly trying to hold it in as it slid free. Once the head of his penis reached her sphincter Moroto dropped his weight back into Emilia, thrusting his cock deep into her anus with the loud clap of a drum. Over and over and over again Moroto pounded into her ass, each thrust accompanied by the beating of bongos and the pure primal moans and cry of two primates in heat.

“Oh~ Agh~ More~ Agh~” Emilia could only spasm underneath the silverback gorilla as he continued on for hours. With Moroto's size and build he had enough stamina to put a race horse to shame as his neighbors got a six hour drum solo to the sound of their passionate night of sex. Emilia’s stomach and intestines were coated and bulging full of cum, her anus puffy, swollen, and gaped to the exact size of her lover's cock.

------------------

Emilia waddled down the dirt road, her tail swishing happily behind her as she cupped her swollen belly. With her new added tummy weight her waddle gave her a rather loud one-man drum band that followed directly behind her. It had been a little under a year since she found herself trapped on this island but she found she didn’t really mind it at all. Her and Moroto continued fulfilling their duties, sounding off the drums before and well after sunset each day until the bell tower was fixed. She found herself embarrassed to tell Sakiko that she was happy with her job and didn’t want to stop just because the bell tower was fixed but Moroto had her back. He made up some bullshit that the drums were louder and easier to hear which Sakiko easily agreed to.

With her and Moroto’s nightly fuck sessions it was only a matter of time before she was knocked up. They went to Sakiko to get checked up and were elated to hear that they were gonna be having triplets and, because she was pregnant, they’d use the bell until she had given birth and could raise her babies.

She stopped once she had reached her destination. Standing tall in front of her was the bell tower the village had been using in her absence. Near the base of the stairs leading up the tower was a wooden plaque which read, ‘In loving memory of Morris Chutney- Friend to all.’

“I don’t know what you would’ve thought about this place Morris but…” She paused to wipe tears away from her eyes. “It’s rather nice here. A bit strange but nice. You always loved meeting new people and they would’ve loved to meet you.” She sniffled and wiped more tears away from her eyes. “I talked to Moroto and he was more than fine with me naming one of our kids after you… that way I can still have a little bit of you still with me.” She smiled and placed a lone flower on the plaque before waddling her way back down to the village.
