A cool breeze stirred the flames of the campfire as the last rays of sunlight trailed over the darkening savannah. They were far north, bordering the desert and the nights were much cooler as the heat of the day simply dissipated with the coming of the night. A young creature plodded back into the light of the fire, two large gourds slung over one shoulder and a bundle of what branches he could find burdening his arms. Save for a belt upon which a machete hung, he wore nothing. He dropped the fuel a little ways away from the blaze and placed the gourds upon the ground in front of him. Sitting around the fire were three similar creatures, but they were much larger than the boy, and they differed in another respect as they all sported a pair of large breasts, with two more pair of nipples hidden below them and beneath their fur. One, the largest of the three, nodded to the boy, and he took this as an invitation to sit before the blaze. She closed her eyes and began to speak, her voice a husky purr as she reviewed his accomplishments.

"Your first day has passed and you proved your worth in the hunt." With this she turns slightly to indicate a gutted impala laying near the three. "You found water and bring it to share with your Matriarch and packmates. You bring back the oil of the rleshani plant, that which we use to ease the pain of whelping, many pawfuls of it. These are all useful skills and you will become a valued hunter for it. But you are a male and you will never know the pain of birthing as we have. So to prove you can be as capable as a female, you must experience such pain..."

The boy said nothing, but his throat bobbed as he swallowed his apprehension. The three females stood nearly in unison, revealing that they too wore nothing to conceal themselves. Between the legs of each hung a phallus, each easily larger than the boy's forearm, though thankfully not similarly clawed. 

"Present yourself. Offer yourself for the oil."

The boy did as he was told, rocking on his knees from a cross legged position to one of deference, seeming to bow before the females as he repositioned himself away from the fire, his tail raised and awaiting the application of the oil.

The Matriarch took up the gourd marked with the symbol of the rleshani plant and unstopped it, its narrow neck finding an easy mark between the boy's cheeks. He shuddered as the warm oil flowed over his clenching muscle, down over his sack, dripping from his limp shaft to the ground below. The slightest grin played on the Matriarch's face and with but a fraction of her strength she forced the neck of the gourd within the boy. He let out a yelp, catching himself too late as he showed his first sign of weakness. The Matriarch's grin widened, revealing more than a few off-white fangs reflecting the dancing firelight.
The boy twitched again as his rectum flooded with the oil, the slick liquid soothing his inner walls as it seeped deeper through tight muscular passages.

"You are ready. Steady yourself boy. Prove you can endure as we have endured."

The Matriarch offered a small bag to her compatriots and each withdrew a long leather pouch that they proceeded to draw over their shafts, all the while squeezing and slapping in order to force themselves erect. It did not take long for them to get engorged, the sight of the boy prostrate before them was delicious in its own way and each licked their lips in turn as they surrounded the boy. The Matriarch kneeled behind the boy, taking a pawful of the oil and slathering it upon her length, before pressing the soft tip to the boy's pucker. He hissed as she grabbed his calves and with little warning, buried nearly a third of her member within him. But he did not cry out. She lay back upon the sparse grass, pulling the boy with her, laying him upon her stomach and chest, his head resting between her breasts as she spread his legs wide and offered him up to the other two females who wasted no time spreading his rear further.

"Yip!" Was the cry as the boy was forcibly stretched wider around three pseudopenises, his formerly virgin hole now screaming for him to join with it despite the painkilling and relaxant properties of the oil. But aside from the yelp of surprise, the boy remained silent as the three females drove themselves deeper within him. One paw length, then two, three, four- the long moments stretching as the females jostled their dicks within his guts, jousting for position over his prostate, his real penis pitifully mimicking the phalluses within him.

Then he was full. With practiced flexibility, the females arranged themselves to skewer the boy as deep as they could manage. His once flat belly bulged under the press of the two females atop him, the three cocks within him displacing his bowels to prove their dominance. His breathing was shallow, slight gasps as his lungs struggled against the three shafts poking into them, but he made no sound as he was stretched like a drumskin around the heads of the females. He had passed this leg of the test.

Then they began to thrust. Each female taking turns to withdraw then piston back in, their rhythm quickly established as they angled their thrusts to pull the boy further apart. What little relief the oil provided was negated as the excess poured from him, spilling onto the ground, symbolic of the broken water of birthing. The females began to yelp, claiming the silent boy, crying out with what little pleasure this brought them as the boy remained steadfast, though tears began to stream from his eyes, though his teeth were clenched and his lip bleeding as he strove to stay quiet despite the female's abuse.  

This continued even as the Moon began to rise, the time stretching in sympathy with the boy, riding in silence as he suffered and endured. Even as the females reamed him, even as they sank claws and teeth into him, even as they added a wooden prop into his hole centered between the three, he endured. As the Moon reached her zenith she smiled down upon the boy, the glow of her full body illuminating the empty plains and bringing his test to a close.

With a nip on his neck to mark him, the Matriarch withdrew first, the lack of her girth allowing for the easy exit of the other two females and the toy. She soothed the weeping boy with a gentle lick across his face as he lay in the dirt, rear to the sky as she applied the rest of the healing oil to his wrecked hole.  

"You will recover in time boy, you are now a man of this tribe. You have endured pain as we endure, and though you will never be female, know that you are near as worthy as we..."
As the other two females began to cut up the impala for them to eat in honor of his passing, the Matriarch took a wadded ball of lions mane and healing herbs and wedged it within the boy's hole, wrapping a soft grass cloth about his rear to keep it in place.
"And son... I am proud of you..." She whispered as she licked his face. 
The boy smiled.
