Notes: For the [community profile] seasonofkink prompt, biting. You know I had to do an Ankheiji fic for that prompt. This was meant to be rated M and be a shorter and fade to black sort of fic originally... But then I got deep into my Id somewhere along the way and this became more than what was originally planned. Enjoy some monsterfucking and lots of Ankh being a bitey bird!

Also On: Ao3, Dreamwidth


It was a nice spring day, the weather was pleasant. Ankh and Eiji were still in Japan but traveling around. Away from what would be any semblance of society. Ankh didn’t know, or particularly cared to know where exactly they were. That was for Eiji to worry about. But ever since his revival this was what they did. Phone service wasn’t particularly great in this area… But Ankh would survive.

They’d better get ice cream at some point soon though. Ankh didn’t care how he’d get some, Eiji just needed to provide.

As they walked deeper into the woods, birdsong could be heard. It made a thought begin to creep into Ankh’s mind. It was spring. And he was a bird. Birds get extremely horny around this time of year… But it surprisingly hasn’t hit him yet.

He didn’t feel it was worth dwelling on the thought for too long right now, the true center of Ankh’s focus right now was two things: When would there be phone service? And Eiji better get him his ice cream soon.

After some walking around, they found a nice area to take a rest. The surroundings were pretty flat with a river close by. Surrounded by trees that would be great for shade.

Getting out his map, Eiji expected Ankh to immediately nag him about what was next for their travel plan. But there was silence. It wasn’t right, something was up.

Turning to check on Ankh, he noticed there was something… Different about him right now. He was off-puttingly silent, and his breathing slightly labored.

Eiji wasn't entirely sure what was going on with Ankh. But before he had any time to ask, Ankh’s wings bursted out in vibrant color. Almost iridescent as the sun shined against those feathers. And Eiji could only look in awe whenever they came out. There was something truly mesmerizing about them. Beautiful beyond any words, they were a part of Ankh.

But he didn’t have much time to admire. Before he could even properly react, Ankh pinned him right down to the ground.

His wings were doing most of the work, enveloping him completely and covering Eiji up from their surroundings. Greeed arm suddenly forming, as both Ankh’s hands gripped Eiji’s shoulders.

With his senses heightened from adrenaline, Eiji could hear the nearby river roar in his ears, notice how the breeze made its way through the plants, and hear the birds chirping that were high up in the trees.

Eiji’s heart raced, feeling like it was even going to leap out of his throat. Ankh’s talons dug themselves just enough into his right shoulder where it stung a little, and would definitely leave some marks.

Not that Eiji ever really minded that…

There was something different about Ankh right now. Panting heavily as his irises glowed a deep crimson, almost blazing like fire. His gaze pierced right through Eiji. Such a look reminded him of a hawk going straight for its prey.

His heart could only continue to pound in his chest, as he could feel his cheeks flush and begin blood roar in his ears.

Man, now was not the time to be horny about this!

Speaking up, “…Ankh? What’s going on—” He didn’t have time to finish the question, Ankh began kissing him roughly.

There was tongue and teeth, biting down onto his lip before kissing him again and again. Eiji was unable to keep up as he felt his mind get into a haze, and melt under Ankh’s grip. Moaning as he bit down onto Eiji’s lip yet again. Enjoying the rough treatment, and the hints of pain.

Next he bit around Eiji’s neck. Sucking and nipping across every inch of skin that he could. Leaving what would be several marks. Eiji writhed and moaned, grinding up against him. He couldn’t get enough.

“M-More Ankh… More…” Carding his hands through the curls in Ankh’s hair.

Eiji loved it whenever Ankh got rough with him. Whenever he’d bite him, leaving countless marks against his skin. Or his talons leaving pink lines across his chest and back. And making new ones once the others faded. Eiji was just drowning in the pleasure from it all.

Kissing up to his ear Ankh whispered, “You’re mine.” Before nipping at his earlobe.

Those words went straight to Eiji’s dick, heat pooling up inside him. Whining as he ground against Ankh desperately for more friction. There was something about Ankh whenever he got possessive, staking his claim on Eiji, that he could never get enough of.

Ankh knew this and loved it too. Which, good. Eiji was his, after all. A strong feeling of smugness and pride would rush throughout every inch of his body any time he’d think about how much Eiji liked it.

He continued to bite all around Eiji’s neck, collarbone, and shoulders. Leaving his mark, claiming what was rightfully his. Eiji gripped Ankh’s hair, one hand sliding down to Ankh’s neck. Wrapping around it to bring the two of them even closer. Making it easier for Ankh to bite Eiji even more, and more.

It was a convenient thing that he already often wore scarves. Well, convenient for Eiji. Ankh couldn’t care less if others saw or not. Though he always felt a little smug, and a sense of amusement whenever someone was unfortunate enough to spot one on Eiji’s neck.

Eiji was mewling for more, but was made silent when Ankh suddenly transformed into his Greeed form. Breath hitching as he enveloped Eiji even more in this form. Completely towering over him, feeling like prey even more than he did earlier. Dick twitching in his pants as he excitedly looked up at what his boyfriend truly was.

The pace only ramped up from there. Kissing him again, it was even rougher. Eiji was completely lost in the feeling of how Ankh’s lips in this form felt compared to his human one. It felt different, in a way he couldn’t really articulate. It wasn’t human skin. The best way one could describe it was that it felt smooth, cool, and almost leathery.

But it felt so, so good. Kissing back, he needed more. More.

Once again grinding up against Ankh as much as he could. Even more desperate than earlier. Needing all the friction he could possibly get from a body which was so different compared to his own. All of those grooves, edges, and textures. When Ankh reciprocated, grinding back up against him— He gasped out a moan.

Ankh chuckled before biting around Eiji’s neck some more. Savoring and taking in all of his reactions. How his body trembled underneath his touch, all his whimpers and moans, taking pleasure in how this form would always make Eiji become completely undone.

Eiji was left absolutely breathless and ecstatic as Ankh kept biting his neck, and grinding up against his dick. His talons slowly dragged across his chest, the combination of bits of pain mixed in with pleasure was completely intoxicating. Leaving more marks across his body, pink lines decorating his chest.

“Mmm… Ankh— More, please—” He begged, eyes hazy with lust.

Pulling down Eiji’s pants in a swift motion, Ankh’s dick then came out of its hiding place. It was a bit windy, having a bit of a curve along with some ridges, and purple. Eiji was unable to look away, feeling goosebumps form all across his body. Aching to be filled already, his excitement was palpable.

Ankh’s wings swiftly went up, a burst of wind and feathers scattered around them as well. Freeing Eiji from being enclosed. Then pinning him against the closest tree, his back pressed up against it. Eiji wrapped his legs around Ankh’s waist as he entered him in another swift motion. He gasped and tightened the grip of his legs around Ankh, needing more.

Arching up into him, Ankh was getting a few more bites in. Then pounding deep into Eiji with a frantic pace. Muttering “Mine. Mine.” with each thrust for the first handful of them. Before being so overcome with pleasure that he could only grunt and moan with each thrust then on.

Eiji felt amazing as Ankh continued to fill him up. Ridges from Ankh’s dick rubbed against his prostate, sending shock waves of pleasure throughout. Melting from the roughness of his thrusts, the heat Ankh’s body emitted, and how deep he went. Now unable to form any sort of coherent speech as his brain short circuited.

He was so pent up from earlier that he could barely last much longer. Ankh was also the same.

Eiji came first, the stuttering of his hips being what pushed Ankh against the edge. Putting in one more thrust that was deep, filling up Eiji and then pulling out.

The two panted as they slid down and curled up against the tree together. Ankh wrapped Eiji with his wings, holding him close. Eiji rested his head and snuggled up against the soft feathers that surrounded Ankh’s neck as he drifted off into sleep. It wasn’t too long after that Ankh dozed off as well.

When Eiji woke up, Ankh was awake and had already reverted back to his human form. His line of sight was focused at the birds up high into the trees. Which were singing their hearts out. There was a look of thoughtfulness in his eyes.

Finally Eiji had a chance to ask. Still a little groggy, his voice was sleepy. “Hey Ankh, what happened back there?”

He scoffed, “Isn’t it obvious?” Not giving any eye contact, his gaze was still focused on those birds.

Ankh was already back to his usual self. But there was a comforting familiarity to it that Eiji had come to appreciate since he was revived. Over the years, he realized just how much he ended up missing it deep down.

Nevertheless, Eiji still mumbled as he fixed up his clothes. Putting his pants back on. “Well it’s not that obvious actually—” He noticed how Ankh was looking up towards those birds. One was doing a courting gesture towards another. Gears quickly began to turn in his head, and it all made sense now. “Oh!”

“You’re always an idiot.” Speaking with a smirk.

Eiji smacked his shoulder, and that’s what it took for Ankh to finally get his eyes looking at him. Now he was looking offended, instead of being deep in thought.

Groaning, “Well you barely tell me anything! You can’t always expect people to know what you’re thinking!”

“As if I care!” Getting up, Ankh gripped his face. A gesture Eiji was all too familiar with, his cheeks squishing in Ankh’s hand. This too, was something else he also missed. “Just get me today’s ice cream already.”

Ankh! We’re nowhere near anywhere that sells any—!”

Scoffing again, Ankh turned away. Petulantly crossing his arms. “That’s not my problem.”

Both of them kept bickering by the river, as Eiji charted out the rest of the course for their trip. Noting that the closest town was at least a couple days away. And Ankh wasn’t happy about that… Promptly biting the tip of Eiji’s nose when given the news.


End Notes: Yes it's over well halfway into summer, but Ankh being a horny bird suddenly because it's spring is a evergreen concept. I meant to write something like this back during spring... but it just didn't happen. Life and all. But I had to get a fic like this out of my system, seasons be damned!

Some behind the scenes fic details:

Bird behavior was implemented! It's based off mantling. I got the beginnings of an idea from this tumblr post. I was talking about Ankh mantling with some buds and my dear friend mostlyjustgoose said "Except instead of trying to kill him he’s just giving bitey chaos kisses" and those were the inspirations for this!

As mentioned above, with that inspiration in mind this was originally meant to be rated M, be a bit shorter and fade to black fic.... Things ended differently lol! But I had fun with this and am very proud of how it came out, especially with all the diligent work I did. I hope you enjoyed reading it as much as I enjoyed writing and working on this.

And how I described the shape of Ankh's monster dick is based off of a design drawing I did for myself a while ago. (18+ art. That is a bird monster dick!)

Say for the color, which the fic A Heat-Seeking Greeed is where I got the idea of it being purple, which I like more than what I originally came up with for a color scheme in my own art. This is a fic my friend did for me for an exchange! I adore and cherish it. If you want some more ankheiji monsterfuckery in your life, please do go check out the fic and give it some love.
