Jac blinked. Several times. Jac was staring in awe at the wonder that had just entered his field of view, simply frozen with his mouth agape and eyes wide. It... was almost the size of Jac's entire forearm! But even thicker!

Thorax simply smiled nervously as the pegasus gawked in awe at his member, his cheeks flaming redder than a tomato. Jac could not bring himself to say a word, for he simply did not believe such a size were possible. Ponies were notorious among other races for having disproportionately large penises for their size, but... not like that.

"Did... is this, um... am... I... is this too, uhm... too far?" It was Thorax's concern that momentarily snapped Jac back to his senses, reminding Jac that he had a love bug to keep happy. He didn't have time for anxiety, because his king was concerned and Jac needed to fix that.

"N-no! No, Thorax! I... I..." Jac bursted in an attempt to comfort his newfound partner, eyes still affixed firmly on the prize. "I..."

As the mango king began to understand what Jac was feeling, Thorax's nervous grin slowly shifted into a more sinister, playful expression. Jac felt Thorax's hands gently press against his shoulders, startling him slightly and sending a small gasp out of the shy pegasus' lungs. The changeling set his gaze directly towards Jac, closing his fingers into a tight squeeze of Jac's shoulders, squeezing and releasing firmly and at a slow rhythm. Jac did not return the gaze, but he knew Thorax was staring directly at him. As a result, Jac's breathing stopped completely.

"Do you want it?" Thorax whispered softly into Jac's ear.

Jac remained motionless for several more seconds, only focusing in shock at Thorax's monster cock. This was the absolute biggest, thickest, and most absurdly delicious looking cock Jac had ever seen in his life. The gods themselves had sent a gift from worlds beyond, placing it right in front of Jac - and it was this penis. It began to twitch with the changeling's arousal, still resting against Jac's leg and sending small tingles up his similarly-sized appendage every time Thorax's blood pumped.

"N- no, I... I..." Jac continued, closing his eyes.

"I... need it."

Thorax would have smiled, but only if Jac had given him the chance. He immediately felt a warm, wet enclosure wrap around the tip of his penis as Jac made a beeline to service his king and taste his delicious citrus flavor. As he did so, Jac squeezed his arms tightly around Thorax's waist on either side.

"N-NNNGGGGGYYAAAAAHHHHHHHHH~!"

In an instant, Thorax burst out in a loud, sensual moan as the tip of his penis was treated to a soft, gooey heaven. Thorax's outbursts continued with each movement of Jac's head - a lick, a suck, a bob - creating a steady rhythm of adorable bug noises paired with the soft moans coming from Jac as he serviced his king. Jac worked his way further down the shaft, doing his best to push the king as far in as he could. While this ultimately did not get him very far, Thorax absolutely did not mind - his wings were buzzing rapidly, casting the love surrounding them into a fine dust behind him before seeping into the ground alongside the rest.

To assist himself, Jac began stroking the shaft with both hands as well, causing Thorax to buck and thrust into them forcefully. Despite these motions slamming the back of Jac's throat violently, it didn't matter to him - Jac had a duty to fulfill, and he would stop at nothing to do it.

"Ngh- hah!- nggg- ngghhh- nghyyyaahh- ngah- hah- nnnngggghhhh...

Hearing the sound of Thorax's joy only increased Jac's determination, and by extension, Thorax's pleasure-driven movements as well. It was an infinite loop of arousal, cuddly moans, and love. And both of them knew this was only the beginning of what would rapidly become the best few days of their lives.

Jac's speed increased yet again, now a rapid-but-steady bob of unrestricted pleasure. Thorax's moans began to border on screams ("AAAAAgGGGhh!- HHHaaaAHHHH! NNGGGGGHAAAA!"), and his wings had begun buzzing so quickly they were practically invisible. The intensity of these sensations caused the mango king to subconsciously grab the back Jac's head and forcefully yank it closer to him - immediately thrusting the entire length of his monster cock into the pegasus' throat.

Not a sound could escape Jac; his throat was plugged with something larger than anything he had seen before. His throat bulged from the massive member inside it, extending all the way down to his chest - even the medial ring was clearly visible from the bulge. And despite the apparent danger to Jac's survival, Thorax continued thrusting, swabbing the entirety of Jac's throat with relentless intensity. What Jac lacked in verbal ability he made up for in movement and expression; he looked to the sky as if thanking the gods beyond for the gift he had been given, holding Thorax's rear and assisting his movement. It was a miracle such a situation didn't kill Jac, for surely his organs shouldn't be able to handle such stress - but they did.

Jac still hadn't noticed that he had already came.

Twice.

Cum had begun to stream from Jac's cock in an unending torrent, as if pre-cum, orgasm, and post-cum had all unified into an unending loop of continuous production. It was impossibly long, and impossibly pleasurable - Jac was shaking so violently that his involuntary spasms alone would be enough to stimulate the most resistant penis to orgasm in a minute.

His mind was in the heavens, lost in the unending feeling of changeling love deep inside him. The moans and screams lengthened, until Thorax was practically emitting a constant flow of the most beautiful sounds Jac had ever been blessed enough to hear.

Jac would never let go, he would ride this moment until the sun burnt out and the sky fell down. He would serve his mango king for all of eternity and more, for Thorax deserved the world. To Jac, Thorax was many things- a king, a lover, an adorable and sweet boy, a precious love bug, and countless others he wouldn't have the brain power to think of for ages. Jac promised himself, despite all that was happening, that he would protect this bug and make sure he was happy if it killed him to do it.

Jac knew what it was like to be alone, and he couldn't stand the thought of his precious love bug being condemned to the same fate. Not even for a moment. Thorax thrust in once more, ramming Jac's lips against his pelvis and extending his throat bulge all the way to his collar bone. The changeling king began to unload a seemingly infinite amount of seed, pumping with the force of a thousand pressurized washers. Jac felt like he could be filled no more, and then proceeded to be filled thrice as much. It was a meal fit for a king.

And it tasted delicious, because it was made with love.

Both an eternity and an instant later, Jac felt as if his entire body consisted of nothing but semen. He was pressurized like no pony had ever been pressurized before, and loved like no creature had ever been loved. He could no longer tell if he was laying on a bed or soaring through the ethereal void, for all sensations had been replaced with nothing more than the most fiery and intense arousal Equestria had ever known.

And it wasn't until Thorax's semen began to stream steadily from Jac's rear when the pegasus finally slipped out of consciousness. Thorax decided not to remove his penis, perhaps in fear that the poor pony had developed a dependency on it for survival, so the changeling merely sat there with his entire length deep inside the unconscious pegasus. Much like Jac, Thorax also found himself simply lost in the bliss of his first round with another pony, unable to think or perceive much more than the pleasure he had just experienced. The citrus-flavored love bug breathed and moaned - far more softly, this time - as his own semen puddled around the two of them on the bed, having been the entire way through Jac's body and now back towards the source it came from.

Even from within Jac's dreamlike trance, he could still feel the changeling king stroke him softly behind the head and scritch his ears. He could still hear Thorax singing a soft lullaby to him, about how precious and beautiful the sweet pony was as he slept. And he could still feel the precious love bug wrap his legs around Jac's shoulders and slowly begin to drift to sleep while still lodged deep inside him.

"You... produce love better than any changeling," Thorax whispered softly, amazed at the love both of them had produced together. "And this, Jac... this is the power of changeling love in its rawest and purest form, my sweet and beautiful boy."

Thorax leaned down and kissed Jac square on the forehead.

"Mmmmmmmm...~", Jac hummed.

"I love you~"

And in an instant, the two were asleep.
