The hunting party throws off their leafy camouflage, revealing four more curvy green goblin girls. They quickly play a pair of something that must be a local equivalent of rock-paper-scissors. The losers step down and start cajoling and corralling the rest of the goblins into lining up to wait their turn.
The winners climb up on top of the altar on either side of the elk-man, panting eagerly. The pair of winners quickly pounce on the elk-man's wobbling erection from either side, squeezing it between their lewd little bodies and stroking it with all four available hands. The elk-man lets out a plaintive groan, flexing and straining against the unyielding stone bondage as his erection swells and firms under the goblins' attention.
He bleats in alarm one last time before moaning as his cock erupts, spraying sticky white fluid up from between the pair of nude goblin girls. His cum rains down on the goblins, who throw their heads back and bask in the gooey rain, and also onto the stone of the altar all around them.
The goblins smear their fingers through the cum, spreading it over the altar. Then, they each slap a hand down on the stone and call out in chorus, "LUST OVERFLOWING!"
An ominous red glow bleeds through the seams in the stone altar, forming patterns and sigils. This... is not rune-craft. This is something... older, and more primal. Something almost... alive.
The elk-man's entire body flushes, his eyes going wide as his flagging cock suddenly leaps to full throbbing hardness. One of the goblins removes the leather strap from the base of his now-towering cock, which trembles and then launches a solitary spurt of cum into the air. The elk-man writhes in his bonds, a high-pitched, desperate whine bubbling out of his throat with each breath as his hips shake.
The goblins all watch raptly as the lead hunter leans in and ever so gently flicks her tongue against the elk-man's glans. He erupts instantly, his straining cock shooting three distinct spurts of cum into the air before returning to its previous state.
A raucous cheer goes up throughout the goblin tribe, while the elk-man whimpers.
The first hunter wastes no time, standing up and mounting the tip of the elk-man's ensorcelled penis before plunging down, impaling her small body deeply on the massive shaft, air rushing out of her in a wheeze as his girth crushes aside her innards. Her eyes roll up in her head, her body shivering as the elk-man lets out a muffled wail and his cock visibly pulsates, pumping spurt after spurt of cum directly into the goblin's womb.
The goblin huntress' belly starts to swell, then drips of cum leak out of her, running down the elk-man's shaft to drip off onto the stone beneath him. The glow of the ominous sigils intensifies, radiating lust out over the goblin tribe and even reaching Mira up in her hiding spot.
That first goblin pops off the captive male phallus, flopping aside in a spray of fluids. The second huntress instantly takes her place, impaling herself and shuddering in pleasure as the elk-man's cock spasms and floods her womb. She finishes is much the same fashion, and another goblin girl takes her place.
One by one, each of the thirsty goblins impales herself on that throbbing dick and lets her pussy milk out enough semen to stuff her womb full. Then each one crawls away, collects a cooked steak, and gnaws on it as she lays in a puddle of cum and watches the impregnations continue.
