Metropicalis – a jungle city on a tropical island nearly twice the size of Australia with lush green trees filled with fruit and exotic flora and mild warm climate. It is home to anthropomorphic primates of a variety of species including simians, orangutans, gorillas, mandrills, etc. and some can have an odd and rare variety in the color of their hair/fur. But their feet are more akin to humans, plantigrade with a big toe.  Their homes can be found in one- or two-story treehouses, apartment complexes made from hollowed out trees, houses, stores and buildings on the ground, and even in cavern systems in the mountains. Vine swinging is their main mode of transportation. Some of the modern technological conveniences exist like refrigerators, microwaves, and TV are the high extent of this world. Also, like a nudist colony clothing is nonexistent save for some wear in the workplace like helmets, aprons, and the like.
Meet the main subje-…er character of this story, Torke Tarzanian. An anthro gorilla who stands 6’7” ft tall with dark navy-blue fur/hair all over his body except for his face with sideburns, ears, chest, crotch, hands and feet that is leathery silvery grey skin. His physique is more like a runner’s build with strong pectorals and 6 pac abs and his male hood is nearly ten inches long. His arms and legs are at even length yet less bulky still showing off sizable biceps and calves for lifting tremendous weights and running long distances. An Adonis ape.

“98…Unh…99…Agh….100! There!” a nude muscular dark navy-blue gorilla with silver grey leathery skin grunted as he put the 100lb barbell back onto the steel holding pegs of the weight equipment. 
He got up from the padded bench and grabbed a grey towel that hung on the equipment, wiping away the dripping sweat from all over his head. He grabbed the plastic water bottle and took a big refreshing gulp. 
Looking around the bambooed and padded floor gym as the early afternoon sunrays peeked through, seeing plenty of fellow gym going primates in various workout stations. From right side of the double door there were weights and pumping iron equipment while the center had the cardio with treadmills, stair masters, bicycles, etc. The left wall was half and half with the front desk, manned by a female white-haired gorilla with dark leathery skin and D sized rack who was reading a Primetime Primate magazine and ab/stretches/yoga station with mats and medicine balls. The back of the room too was half and half with a men’s and women’s shower/locker room on the left and the sauna on the right with a small rectangular viewing hole that can be slid closed.
After completing his two-hour workout regiment, Torke grabbed his stuff and headed over to the front desk before ending his day at the gym in the sauna. While strutting a bit towards there, he ogled some other female simians who bent over to pick up weights, showing their big baboon sized booties, and those running on treadmills as their hips swayed and large behinds and tits jiggled. One of the reasons he loved going to the gym, seeing and meeting hot chicks. 
“Hey Villi, my, my, aren’t you and the twins looking lovely today.” he commented while looking at her boobs as he leaned on the desk.
“Yeah, yeah, yeah….*sigh.” She answered with a hint of annoyance, still flipping through the pages of the magazine and barely making eye contact.  
She was initially put off and disgusted by his constant advances to her but managed to get used to it and shut him down easily. It helped that she threatened to kick him out of the gym for good and call the cops if he gotten too close to her. But that didn’t stop the horny ape from bothering and hitting on the other female gym members, causing some to not come back. Bad for business. However, this the day that might change all that with what she had in store for him. 
“So, you going to hit the sauna before you leave?”
“Heh, you know me too well. Especially, for one who turns me down every time. Having second thoughts?” 
“Hah, you wish! But I do might have something that can help you.” she replied with a light smirk. She reached behind the desk and pulled out three pink crystals the size of baseballs and place them on the counter. 
“And these are?” Torke asked quizzically.
“They’re special purification crystals. Just put them on the heated rocks in the pit and they’ll dissolve into a rejuvenating gas that relieves the pores and causes the body to be more relaxed. Not to mention it’ll leave a sweet lingering scent that I’m sure it’ll make the females swoon all over you.”
“Eh? Sounds like some new age type of crap. Not gonna charge me for it are you?”
“On the house, just for you.”
“If it’s free, guess it wouldn’t hurt to try.” He said, swiping the crystals off the counter and heading towards the sauna. “Thanks!”
“You’re welcome…” Villi replied. 
“…prick. I hope the crystals will work and change him for the better like that witchdoctor said it would.” She added when he was out of earshot.
After finishing his water bottle, Torke, now with the towel wrapped around his waist, opened the dark mahogany wooden door to be greeted with blast of hot steam. The slightly fogged up room was entirely wooden with evenly sized light brown planks from the ceiling with its only hanging light to its walls with benchlike seats jutted out and much of the floor. In the center had a four-foot leveled circular pit of heated stones with a temperature regulator knob on the side. 
“Aaah! Feels good in here! And I get the sauna all to myself too, sweet!” He said as closed the door and viewing hole behind him. Then he looked at the crystals he had in his hand.
‘Might as well try the crystals out. What harm can they do?’ he thought to himself as he tossed the crystals into the hot rocks.
Their reaction to the heat was amusing as they seem glow a hot pink among the embers. It wasn’t long until they began to slowly dissolve as the steam slowly turned into a misty pink and his nose picked up a whiff of the fuming fog.
“*Sniff…*Sniff…Mmm…is that…raspberries I smell? Heh, just like Villi said that it had a sweet scent. I guess this new age stuff isn’t so bad after all.”
Torke took a seat on the left side of the room.
“Aaaah….” He sighed in deep relaxation as he undid the towel around his waist, exposing his flaccid banana. 
“This is really nice…*Yawn…” 
With his eyelids getting heavy, the gorilla began to nod off slightly as he was getting a bit too relaxed. Soon, sleep overtook the ape as sweat dipped and clung to his fur. 
When the crystals fully dissolved, another one of their properties took effect as he slept and breathing in the pink fumes.
His muscular frame slowly deflated. Where there were once hard rippling muscles, now gone while losing a foot in height as well.
His feet shrank a few inches, becoming petite with dainty toes. Up to his legs, they took a more womanly and slender shape with thicker thighs. 
He moaned as his limp dick suddenly sprang to life as it went fully erect. But then, it began to shrink by the inch as his shaft receded into his body along with his two ‘guavas’. Two fleshy pussy lips took their place, resulting a stream of precum dribbled from the seat and onto the sweat puddled floor.
Soon, cracking was heard as his hips began to widen to childbearing levels as his waist shrunk, giving him pear-shaped or hourglass figure. His bum bloated with couple layers of fat with each cheek nearly the size of a ripe coconut. 
Another moan escaped his lips as he felt pressure in his chest. Two fleshy mounds began to grow, developing into FF cup tits the size of large watermelons and fat erect dark nipples with large areolas.
Like his legs and feet, his arms became slender in tone while his fingers gained a thinly and dainty form. His shoulders narrowed soon after.
He grunted and groaned as the final changes were applied to his head and face. His facial features softened and became more feminine as his nose shrunk and narrowed, longer eyelashes, and smooth chin with his head looking rounder. Long navy-blue hair grew from his scalp and flowed down until it reached his lower back.
The pink steam dissipated, returning to its normal color and leaving the hunky gorilla guy turned into an attractive gorilla girl alone. 
But there was still more happening to her body as her newly developed pussy began to grow hot. This made her slowly stir a bit from her slumber as her hand subconsciously reached down and rubbed against her slit. Fingers slowly pumped in and out slowly as she emitted feminine higher pitched moans. When the climax was reached, she gasped as her vagina squirted onto the hot floor, sizzling and evaporating.
It was then she realized something was wrong and fully awoke from her half sleep state.
“Hmm....Huh…wha-?!” she stopped, noticing now the change of voice.
She looked down to see some long flowing hair, huge breasts, lack of muscles and male genitalia. 
“H-HOLY KONG!” she exclaimed as she got up and gave her body a once-over, cupping and giving her boobs a big squeeze that made her moan. 
“How did this hap- Wait! The crystals! Grrrr! That Villi is going to- OO~ooooh!” she was interrupted from her thoughts as her snatch ached with pleasure, making her body shuddered and legs buckled. 
‘Am-am I in heat?!’ she thought to herself while panting and massaging her crotch area that was in dire need as body nectar oozed down her thighs. ‘Good Grodd, is…is this how sensitive females are? My body…it wants- it wants cocks! Long, hard, and thick! I n-need them so bad! ARGH! Can’t think straight! Need to-!”
Again, her thoughts were interrupted as the door to the sauna opened, making her stop her masturbation session immediately. In walked a brown furred gorilla with white towel wrapped around his waist who was a foot taller than her with tan leathery skin as indicated on his hands, feet, chest, face. He also had distinct chin and scar on his left pec. Speaking of which, his face had a moment of shock upon entering, not expecting to have any company esp. a gorgeous gorilla girl.
“Oh hello! Don’t mind if I join you?” he asked.
Torke just shook her head in response, blushing a bit at the beefy hunk of a newcomer as feminine thoughts and hormones flowed through her body.
“Ah that’s good. Name’s Jorik, your’s?” He said as he sat down next to her sweat soaked towel while unfastening his, revealing a large nearly eight-inch-long flaccid dick.
“T-Torke.” She managed to mutter out, blushing as she eyed his cock and shyly looking away not to stare. 
“Nice name. Hey, you look kinda tense. Come here and sit down. I promise I won’t bite.”
She took a seat on her towel next him as asked.
“*Sniff--sniff….*Sniff…” 
His nose took in a strange scent that was slightly yet noticeably different from the sweaty odor in the air. It seems it wasn’t enough to hide her heat.
“Are…are you in heat, miss?” he asked.
“Yeah…but I don’t mind.” She replied, fidgeting a little as her snatch began to ache for male meat. 
“You sure? You seem to be anxious. And I’d wouldn’t mind helping a fair female in distress.” He said as his shaft steadily grew to over a foot length. “Hop on anytime you like, dear.”
Again, she flustered at the offer and now can’t help staring at his crotch, female hormones and a wanting pussy not helping matters. Her body was giving in.
“Ooooo~h! O-okay, I- I’ll do it!” She said aloud whilst mid-orgasm.
She got up and knelt on the seat, facing him as their genitalia touched. Jorik held her steady with his hands lightly gripping her hips while Torke held onto his shoulders around the neck. 
“Ooooooooo~hhhh!” 
She moaned as his big banana slid into her, throbbing against her sensitive flesh walls, slowly pumping in and out. Her body shuddered and twitched from the sensations that coursed throughout, shaking with pleasure. As she rode him, her breasts and butt bounced and jiggled like jello.  
“Ah! Haah….haah….Ooooo~h! Ook- Mmmph!”
“Ungh! Ook-haah! Oooo~h! Ah!”
The primate pair’s grunts and moans quickened and grew louder as they picked up the pace, holding tightly onto each other while pumping faster than before. Jorik’s hand groped her tits, eliciting even louder moans from her, which thankfully the door to the sauna muffled much of the noise. Then their lips locked into one long tongue entangled kiss. However, she broke it as the climax reached its peak.
“Aah! Oooh! Haah! I’m-I’m CUMMING!” Torke yelled as she creamed all over his monster sized member.
“Ungh! Ah! Oh-Me! ME TOO!” He replied as he unleashed his hot load into her womb.
After their respective orgasms, they rested for a while, still in their sex positions drenched in dripping sweat and panting. 
“So, how about we take a shower and continue this back at my place?”
“Oh, I’d love to!” Torke replied, showing how much that masculinity faded.
After they showered off, the new gorilla couple left together with Torke lovingly clinging onto Jorik’s arm.
Villi just watched them with a smile, knowing that it worked out for everyone in the end and that it’s one problem of hers solved.
The End
