In a cave with large openings in the ceiling that provides sunlight for lush grass, plant life and even some trees to grow. It was the size of a football stadium with a sizable pool of freshwater that fed from an underground source and flowed out to a cave entrance further away.
In the middle of all this was a tree that was directly under the largest opening in the ceiling. It was not the tallest tree in the area but there were no other trees surrounding it, only grass and some shrubs.
At morning's first light entering the cave, a wisp of ethereal blue light peeked out the trunk of the tree. It slowly circled around the tree it came out of then proceeded to zoom off thru the underground cave, it chased after a few insects for fun, frolicked with some butterflies, checked in on some bird nests with chicks in them and made some playful circles around a slime that tried to follow it.
As it was playing around in the cave, the wisp stumbled upon something new. At the edge of the pool it saw something that washed up. Upon closer inspection it was not something but somethings, there were two of them…. Whatever they were…. The bigger one was wrapped around the smaller one and covered in scrapes, cuts and bruises while the smaller one seemed to be just unconscious.
The wisp circled around the huddled creatures before trying to touch them, just as it closed in on them, the bigger one coughed out some water and started taking deep breaths between coughs. This surprised the wisp and it quickly flung itself behind a rock then after a few seconds peeked at the creature from behind the rock.
After the bigger one was done coughing up water, it turned to the smaller one and started prodding and shaking it which also resulted in the smaller one coughing up water. This is new, new is interesting and fun. The wisp decided to watch these creatures.

Grud jolted awake and started coughing up water, his body was aching after the injuries from fighting the wolves and ramming into river rocks while protecting Nita as they were pulled along the river's flow. After he was done coughing, he looked down and saw Nita. Fear gripped his heart as he prodded and then started to shake Nita to try to wake her up while calling her name.
Thankfully after a few seconds she too jolted awake and coughed up water, then Grud turned her over to pat her back while she coughed up the rest of the water. When she was done coughing Grud asked "My love, are you ok? Are you hurt anywhere?" Grud fussed over Nita until she silenced him with a peck on his lips "Stop fussing over me, I am fine. But you are covered in wounds." Now it was Nita's turn to fuss over Grud with a loving smile.
While Nita was cleaning Grud's wounds by the pool of water, she asked a question that was on both their minds "Where are we?". As they both looked around Grud replied "I don't know but seeing that nothing attacked us while we were unconscious seems like a good sign." Grud noticed Nita shivering and looked around for a good place to rest. As he turned around,
a lone tree bathed in sunlight on slightly elevated ground caught his eyes. After Nita was done tending to his wounds, Grud got up and helped Nita to her feet then said as he pointed to the lone tree "Let's head to that tree and warm ourselves up while we let our coverings dry".
After making their way to the tree, they undressed themselves, Grud's eyes were locked on Nita's generous curves and started getting hard and as Nita looked back at Grud's erect penis, she noticed that her husband's balls were hanging a bit lower than before.
Nita came over and Grud bent down to meet Nita with a kiss. While they were kissing, Nita reached down with both hands to cup Grud's balls and noticed they were a lot heavier than they normally were even when they were full.
Nita thought back while massaging Gurd's balls and realized that ever since they were married, there was not one day that Grud went without pumping a couple liters of cum into her until the tribe had to start traveling to The Ancestor Rock.
After the first night on the journey where Grud fucked her until her legs were shakey and was not able to walk properly, Grud ended up having to carry her for half the day. After that they limited sex to giving Grud a handjob, blowjob or tit job before she was too tired to continue due to the long day's travel. Traveling with breasts the size and weight of two grown men's heads held up with her bra was not easy for a woman of her small size.
Bring restricted to just one ejaculation on inconsistent nights was almost torture for Grud, as most nights Nita would fall asleep the moment they layed down and latched herself onto Grud to cuddle while she slept with her breasts squished onto Grud, while he also tried to fall asleep.
"My poor husband, as your wife I have neglected your needs for too long." Nita pushed forward and Grud let himself fall backwards gently while bringing Nita down along with him. "You just rest now and let your wife do her womanly duties" Nita said coyly.
Nita brought herself between Grud's legs, then sandwiched his dick between her huge boobs and started stroking. As usual upon the first down stroke, his foreskin peeled back and unleashed another two inches of dick.
Nita was intoxicated with the smell of his dick and started licking his dick while stroking it with her tits, soon after she started sucking on the tip, followed by fitting the penis head in her mouth. It was not easy when Nita first tried to give Grud a blowjob, but after over a month of trying, Nita managed to fit Grud's dick in her mouth.
While Grud's dick was in her mouth, Nita's tongue danced over his penis head while sucking as hard as she could in an intoxicated trance and soon after Grud's seriously backed up balls released his first jet of cum in most likely three days.
When the jet of cum hit the back of Nita's throat, she almost gagged but instinctively started swallowing like it was her first drink in days, but the load of cum Grud was shooting out was too much for Nita to swallow fast enough and the extra started leaking out her nose. But that did not stop Nita, the moment she got a chance, she snorted back the cum in her nasal passage so she could breath again and continued sucking.
While Nita was savoring Grud's cum, she was continuously climaxing while milk was leaking from her nipples. When Nita was done sucking, Grud had cummed two more times and Nita's stomach was slightly bloated from swallowing Grud's jelly-like cum. The moment his dick was out of Nita's mouth, Grud sat up and pushed Nita down, grabbed both her breasts and started sucking the sweet and rich milk from both her nipples at the same time, this made Nita climax even harder.
Soon after, Nita noticed her breasts felt lighter and the soreness in her breasts she thought was just from the long two weeks of travel, started to subside as her milk tanks were being drained by her thirsty and hungry husband.
While Grud was sucking on Nita's tits, he had to hunch over to position his dick at her pussy entrance due to height difference. When he was in position, he started plowing her while listening to her sweet moans, seeing the sloven look on her face with her tongue out and eyes rolled back.
Even after Grud stretches Nita's pussy out on a daily basis, her pussy was tight as the day Grud took her virginity due to the mutating agent that is constantly being introduced into her system, repairing any damage and even making her vagina more elastic. Whereas last time she could only take in half his dick, now she could take in three quarters of it.
As Grud released Nita's nipples from his mouth to concentrate on properly fucking his wife limp, he admired Nita's beauty and the bulging outline of his enormous dick as it was rammed inside of her going up past her belly button.
The sight of this fired him up, causing Grud to increase the speed of his hips and after Nita lost count of how many times she climaxed, Grud finally shot his load directly into her womb for more than a minute while he watched her womb inflate from his cum. But from the size of his balls that still looked and felt full, this breeding session was far from over.
It was more than six hours later, that Grud released his final load into an passed out Nita that now looked six months pregnant, when Grud pulled his flaccid penis out of Nita, very little semen flowed out due to the very thick viscosity of Grud's backed up semen. But he was too tired to notice that, so he pulled Nita into a cuddle and fell asleep in the afternoon sun under the shade of the tree.

All this time while Grud and Nita were doing the Nasty, a certain wisp that was invisible to most was peeking at them from the trunk of the tree they had been fucking under. It had seen animals mate before but the intensity of this mating session it was witnessing was abnormal even from its limited understanding.
It was wondering 'why was the male mating with what was obviously the female's mouth?' and when the male ejaculated in the female's mouth, besides the moaning, there was actually sound being produced from the gushing of seed being shot out from the male.
Another thing that amazed the wisp was the amount of seed being produced, to the point of the female's belly expanding slightly. Observing this as it had observed many other animals through the years, the wisp came to the conclusion that this species of beast must be one of those that dies shortly after mating (even if it was most likely doing it wrong by mating with the female's mouth) but what did it know, this was its first time seeing this species.
After the male had finished its climax, it expected the male to become limp and expire shortly after. What it saw was the male climaxing twice more and showing no sign of weakening. The wisp switched its mystical vision to observe the lifeforce of the two creatures.
When it observed the female, it had stronger and deeper lifeforce than the average animal, then it switched its target to the male, it observed the male and was shocked. Besides its vastly strong and robust lifeforce, its lifeforce was deep as only seen in trees… No…. upon looking closer, the depth of its life force had no end and was quickly replenishing the thick lifeforce rich seed it poured into the female.
As the wisp was observing their life forces it noticed the male push the female down and started feeding on the milk that was leaking from the female's teats and shortly after positioned its penis and penetrated the female. So it did know how to mate properly.
While the male was moving its hips vigorously, the wisp thought to itself 'While binding myself to the tree in this nice and peaceful place for the past couple hundred years was nice and all, this male creature would outlive the tree if it did not get killed. If I am able to also bind myself to this creature, I will be able to travel where it goes and see new things.' while the upside was that if it bound itself to this creature, it would be able to see and experience more of the world, the downside was that binding itself to this creature was risky, in doing so it would essentially separate a part of its essence to bind to this creature while leaving itself weakened for quite a while and if the host of its separated essence were to die for whatever reason, it would be in tremendous pain.
The wisp learnt this lesson the hard way when it was younger and shortly after binding to the tree. It bound itself to a small bird nesting in its tree's branches, a few days later the small bird was snatched out of the air by a bird of prey. The only reason the wisp survived the backlash was because it was bound to the tree.
After a while of weighing the pros and cons of bonding, it decided that as nice as its current residence was, it would be more exciting to explore more of the world and floated its incorporeal body into the male to start the bonding process.
As the wisp made contact with the male creature's lifeforce, it was taken by surprise at the strength of the lifeforce that swept it up in the vigorous flow. This change in situation frightened the wisp as it instinctively felt that it now had no choice but to succeed in bonding or be swept away by the lifeforce and potentially die.
It hurriedly started the bonding process, fortunately the bonding process only takes a short period of time. Just as the wisp's essence was suffused throughout the male creature's body and about to permanently bond, the male ejaculated deep into the female. Part of the wisp's essence was carried along with the lifeforce dense seed pumped into the female, this made the wisp even weaker, as a bit more of its essence was forcefully separated from itself and started to suffuse a mixture of the wisp and the male's essence and lifeforce into the female's lifeforce.
Shortly after the wisp sensed the bonding was successful but the male was very much the dominant one in the bond. After this bonding session, the wisp was too exhausted to do much of anything and fell into a torpor-like state while housed inside the male.

Grud startled awake due to his left foot becoming more and more uncomfortable until it straight up started hurting from a burning sensation. He raised his left foot to see what was wrong and saw his foot engulfed by a blob of greenish transparent slime with an off white in color stone the size of a ping pong ball floating around in the slime.
