Evening was settling over Angel Island with an array of beautiful clear skies. The sunset painted the lands in lush colors of purples and pinks that sparkled off the Master Emerald so nicely. It was beginning to be a quiet night, or at least that's what Knuckles had been hoping for. Once he caught sight of the moon he knew it would be anything but.
It had been broken ever since the Eclipse Canon, but it somehow still had its phases regardless, one of those things nature perseveres even in its destruction. It would be a full moon tonight. In the past that wouldn't have bothered Knuckles, mostly seeing it as a blessing during his guardianship, but now living with a certain someone it made things more…. Interesting.
He and Sonic had been courting for awhile now, and recently decided to become mates fully. It had enriched his life a lot since the hedgehog began living on the floating island full time with him. They had even built a proper hut now, only by the insistence of his comrades, and he'd admit it was a bit too nice. The home wasn't anything abhorrently grand, but had large windows so he could see the Master Emerald from any room.
That didn't mean Sonic was permanently grounded though, no one could ever really pin him down. He'd still be running around on his adventures, saving people and kicking the asses of evil maniacs and gods alike, but he'd always end up back on the island every few days. Nowadays though things have really mellowed out. Eggman was growing old, his schemes slowing down in scale, and made their lives a bit easier.
Sonic was on the island now, and Knuckles wondered if he'd seen the awakening moon. Either way it's effects would soon take hold and the echidna wasn't sure how it would affect him tonight. The moon being broken, while still affecting him, sometimes causes issues when he'd transform into a werehog. In some instances he'd be fine, his same old self but with extra fluff. Other times he'd be more violent, usually that means Knuckles would have to spar with him or try to take him somewhere to let off some steam. The final way was less frequent but was still by far his favorite.
Thankfully it looks like tonight was one of those nights.
From his spot beside the emerald he heard a howl from near their home. The moon was at its peak and taking hold of his mate. He waited, listening, to find the result of his changes. There were no roars, so he definitely wasn't feeling destructive, but there was also no talking he could hear. Worry laced against him for a moment until he could see something barreling at him from a distance.
He barely had time to brace when the large navy werehog pounced him. The beast let out a broken whine that reverberated against his chest and his tail wagged.
“Knuxxxx,” His mate whined, his big eyes needy, “Please I need you…”
His pathetic whimpers shivered straight down his body and right into his groin. Sonic's large head nuzzled against his neck as he rutted heavy against his leg leaving wetness behind.
He was in heat.
Knuckles chuckled lightly and took Sonic's muzzle in both his hands, making them look at each other. The pouty look he was getting was almost comical.
“You big dolt,” the echidna huffed before smiling, “If you want me so bad, get on your back.”
For once it seemed the werehog was being obedient this time, as most of the time he'd be a bit more rambunctious. Instead of teasing or even growling back Sonic flipped on his back and whined again, if a bit impatient. Now with his mate all laid out he could see every bit of him.
He was leaking everywhere, pussy completely soaked without even having to be touched. It made Knux wonder if Sonic had been in the mood before he transformed; he could never tell. Using his pointed teeth the warrior pulled his mitts off to reveal with sharp clawed hands. They had never bothered Sonic, but he still had to be careful. Knuckles used his thumb to slide against the wet folds before spreading it to one side.
Sonic whimpered, his hulking body reacting to the smallest of touches. It was entertaining to see his usually snarky mate reduced to nothing more than this. Amethyst eyes gazed over the lips, their normal tanness now a dusty shade of blue due to the transformation. He wouldn't need any prep this time, not that he thought the werehog could wait for it.
All the pheromones must have been getting to him as he was already out of his pouch and stiffening.
“You're gonna be a good mutt for me, got it?” His warning was mostly playful, but he watched Sonic nod, though his bright green eyes were focused on other things. Mainly the one hanging between his red legs.
With a smirk Knux got in between large fluffy thighs and used his hand to slap his dick against all that wetness. Sonic moaned, like the little easy bitch he was, and did everything to keep himself still. He'd have to behave or he wouldn't get what he wanted.
Putting a clawed hand against the large waist under him he began to grind, biting his lip as his tip kissed against the large clit. His werehog form made everything bigger, not that he minded, he actually preferred it a bit.
Ya see Knuckles wasn't exactly… average for his size. Most echidna weren't, it was just their species. So it was always a bit of extra work to get Sonic ready for him. Normally I'd be a lot of tongue work, which was always the hedgehog's favorite. Knuckles’s tongue would put most people to shame, and almost always caused his mate to become a mess before they even started. Now, however, in his much larger state that was no issue.
Those large pussy folds sandwiched his dick so well as he slid between them, but not yet inside. They were so silky smooth and made him feel on cloud nine. He could feel Sonic's fidgeting under his grip, the way his large claws were gripping into the rock of the temple and chest heaved with pants. Knuckles licked his lips as he finally sank into the velvety heat, a delicious groan leaving his chest.
A desperate howl emerged against the night as he dipped in inch by inch. He was so warm and wet, taking his dick with so much eagerness. It was nothing like when they made love in his normal state. His blue lover could only ever take a few sinking moments at a time before having a moment of rest, no matter how needy he was. Right now though? Knuckles had no issues bottoming out inside.
They stayed like that for a moment, linked deep inside. Knuckles let himself savor the moist caverns while Sonic’s breathing only grew. Once he'd grown accustomed he spent no time holding back. He took a hold of the waist in front of him with both hands and went to work.
Sonic howled in pleasure as the echidna put his full strength into every thrust he gave. He rammed in hard, pulling almost fully out before slamming back in. Their bodies rocked with the force of it all, Sonic's spiked shoes digging into the stone slabs.
“More!” The gruffed voice under him pleaded, “I need more! Breed me please!”
Knuckles huffed before pulling out completely and using his full strength to flip the mighty beast over so he was on his hands and knees. He didn't even give Sonic a moment before plunging back in that pretty presenting pussy. It engulfed him, leaking against the temple underneath as he bashed into its folds. Thick wet slamming filled the air as the beast became more and more unraveled.
He gripped the wagging tail in front of him and tugged it causing a breathy yelp. Knuckles could feel himself succumbing to the pleasure; his dick felt as if it were about to burst. Sonic was so dripping wet he could barely keep himself inside with every move he made. He grabbed his hips before plunging as deep as he could go and spilled himself.
The echidna spazzed a bit as he came inside, those walls clamping down to take every drop. His body felt almost like jelly as he let the last bit of his seed be given away. Knuckles pulled out after a second, member limp and he panted with tiredness. Not a drop leaked from before him, every ounce lodged deep.
He was pretty well spent, but his fluffy mate was far from done. He was jumped without any warning as the werehog slammed him on the ground with a bit more force than needed. His head bounced off the rock and made him see stars for a moment before he felt weight against his body.
Sonic loomed over him, large fluffy ringed hands on either side of his head. That dewy look in his eyes had faded into a dark haze of hunger. He growled down at Knuckles before positioning himself over his limpness, using one of his hands to do so. The guardian barely had a second before his dick was sleeved back into the silkiness again.
His whole body jolted at his tired sensitivity, but soon let himself be bought into the new position. He held Sonic's hips again as the bottom bounced greedily above him. Every wet slap made the werehog pant and growl in his feral pursuit of pleasure. For anyone else the full weight of a creature twice their size would crush them, but Knuckles was thankful he could handle it.
He could feel himself getting hard again, not that he really had a choice. He groaned when he was slapped down on and grinded; his left hand making its way to the engorged clit that presented itself before him. He used the rough pad of his thumb to encircle it, pressing against it. The action made the other male jerk at the sensation, he arched back against the moonlight. He could see, even under all the fluffy, those pretty pale scars that made Sonic who he was.
His lover was getting close, he could tell. The bouncing was becoming sloppy, yet he kept a firm pressure as he circled his clit, teasing against its hood.
A final hard slam and a deep howl Sonic was sent over the edge. He squirted hard, coating everything in his fluids. The rush caused Knuckles to tip over as well, and he shot another milky load into his mate's sweet body.
Purple eyes watched, even in their exhaustion, as the body before him began to shrink in size. Knuckles was able to pull out, wincing a bit as he did so, before catching his regular old hedgehog in his arms. He'd quelled the beast's urges, and now they both laid panting.
Sonic's breathing leveled out pretty quickly, all his unlimited energy spent. He was conked out after all of it and did nothing more than nuzzle up against the white crescent of his chest. They would end up laying there the rest of the night, too tired to move.
They both slept peacefully under the Master Emerald’s glow.
