Even as he thought this, Ashley stared at his son’s face as if looking at some strange creature. Looking back at himself—how he had gone as far as self-harming just to avoid going to a Pheromone party—Nathaniel’s cold attitude was almost absurd. Moreover, such a composed demeanor was, in a sense, almost admirable.
“You don’t seem flustered at all that this period has arrived.”
At Ashley’s words, Nathaniel frowned slightly, as if asking what on earth he was talking about.
“Didn’t you tell me from a very young age that when the time comes for Pheromones to be released, I must take care to let them out so they don’t build up?”
Of course he had. Especially Koi; perhaps because of Ashley’s case, he was exceptionally sensitive regarding that particular issue.
Prevention is a good thing.
Nathaniel was now nearly ten years old, yet he had never shown the typical chatter or overflowing energy of a child. He was generally taciturn and showed no particular interest in his younger siblings. His developmental process was unusually fast; he already read philosophy books that only a college student would understand and easily solved difficult mathematical formulas, but he rarely socialized with his peers.
Occasionally, Koi wondered what Nathaniel was thinking, but there would likely never be a way to find out. Meeting those same purple eyes that looked back at him, Ashley soon abandoned the thought and decided to end the conversation.
“Then, get some rest.”
As Ashley turned to leave, Nathaniel spoke from behind him.
“You don’t need to go out of your way to visit me from now on.”
Those words sounded as if he were telling him not to perform actions he didn’t truly feel. Ashley frowned, but without saying another word, he left the room.
“Where’s Nathaniel? Is he sleeping?”
Koi, who happened to be standing in the hallway, asked as soon as he spotted him, as if he had been waiting. As he peeked into the room, which was obscured by Ashley’s body, Ashley closed the door behind him and spoke.
“He’s doing homework. Let’s go back to our room.”
“Okay…”
It was a shame he couldn’t get a goodnight kiss, but it couldn’t be helped. As they returned quietly to the bedroom, Ashley hugged Koi from behind as if he had been waiting for this moment.
“I missed you.”
Koi released his Pheromones for Ashley, who was taking a deep breath, and said with a smile,
“You see me every day.”
“I always miss you, every single moment.”
At the fervent confession, Koi felt his ears grow hot.
“I… I did too…”
Muttering softly, he slowly turned his head to look up at Ashley.
“I missed you too, Ash.”
At those words, Ashley gave the brightest smile he had worn since returning from work and kissed Koi. As they rubbed their lips together sweetly and let out a sigh, Ashley pulled up Koi’s shirt as if he had been waiting. Feeling the large hand stroking his newly exposed bare skin, Koi let out an excited breath and suddenly asked as if remembering something.
“You were in Nathaniel’s room for quite a while, did something happen…?”
Ashley hesitated for a very brief moment. He would have to tell Koi eventually anyway. It was simply a matter of whether to do it now or later. Of course, Ashley’s choice was already decided.
“Ah, haa, ah!”
Moans burst from Koi’s mouth in succession. No matter how many times he held him every day, every moment, it was never enough. Ashley always felt this thirst. Every time he bit Koi’s neck, drank his saliva, and stirred everything inside him, there was a voice screaming from deep within his chest that it still wasn’t enough.
“Koi, Koi.”
Every time he chewed on the soft flesh, he thought: Will I one day actually devour Koi? His flesh, blood, and even his bones, leaving nothing behind.
I might already be going crazy.
As that thought vaguely crossed his mind, Ashley ejaculated deep inside Koi.
Lying prone atop Koi’s body, who was drenched in sweat and breathing heavily, Ashley playfully kissed various parts of his face. Because he didn’t have the strength to move a single finger, Koi simply left him be and kept his eyes closed.
However, unlike his body, the inside was still greedy. Ashley, who had buried a part of himself inside Koi’s body, noticed it first.
“Mmm…”
Ashley let out a deep, thick groan. The sound coming from deep in his throat was one he made when he was satisfied. He enjoyed the sensation of burying his heavy member in the soft inner flesh, as the inner walls slowly repeated a cycle of contraction and relaxation, sucking it in and letting it go.
As he enjoyed the caress of Koi’s interior, his stomach grew hot again and his member swelled. Ashley waited for it to harden again inside Koi’s belly, and once he felt sufficiently filled, he finally began to move his hips slowly.
“Nnnngh…”
Koi’s moans mixed with the squelching sounds coming from below. With his eyes closed and his brow slightly furrowed, his tilted face was flushed red.
My Koi.
Ashley kissed his lovely partner again, sliding his hips out slightly before pushing back in deep. He barely managed to suppress the urge to ejaculate every time he rubbed against the inner walls. He wanted to stay inside for longer. No, if he could, he wanted to remain inside Koi for the rest of his life.
Without any interference.
But that was an impossible story. They had too many disruptors. Six of them, to be exact. Once one was put to sleep, another appeared; once that one was driven away, yet another appeared, as if they were waiting in line, appearing in an endless rotation. This time was no different.
Knock, knock, knock. Knock, knock, knock. The sound of someone knocking on the door repeatedly could be heard. Ashley moved his hips rapidly, intentionally trying to divert Koi’s attention. As he intentionally thrust roughly below, Koi let out a pained moan.
“It’s okay, Koi. Look at me.”
Ashley whispered, soothing him. He pretended to kiss him while covering his ears to block out the sound, but the knocking continued. A child was hitting the door with all their might with their fist. Perhaps they were even kicking it.
What did it matter?
Even if they were his children, they had no right to arbitrarily disrupt their parents’ time. Right now was a time solely for Koi and himself, and there was no time to allocate to the children. Besides, didn’t the children monopolize Koi all weekday while Ashley was at work?
If so, they should return Koi to him during the time he was at home.
Ashley entered and exited Koi’s interior repeatedly, rubbing against the inner walls. At the sensation of the inner flesh being rubbed rapidly, Koi began to gasp, nearly losing himself.
“Does it feel good, Koi? It does, right?”
The voice asking with a smile was mixed with ragged breaths. Koi barely managed to answer, letting out a series of short, broken moans as if he were aching.
“Yes, nnngh, it feels good, so good. Ash’s cock… feels so good.”
Ah, Koi.
“Ugh…”
Ashley’s brow furrowed and he stopped moving. Feeling the semen that had been boiling in his gut flow into Koi, he gasped for air.
“Say it again.”
Ashley demanded, kissing Koi’s lips lightly, but Koi only blinked blankly. Ashley repeated softly.
“Say more dirty things, just like you did just now.”
Koi’s flushed face turned an even deeper shade of red. Ashley smiled, but he had no intention of letting it slide. Every time Koi used a dirty word, he became so excited he felt as if he would ejaculate on the spot. This time was no different. When he urged him to hurry, Koi avoided his gaze and muttered with difficulty.
“C-C… cock…”
“Whose?”
Koi eventually tried to cover his face with both hands, but Ashley wasn’t the type to let that happen. Quickly grabbing his wrists and pinning them to the bed, he demanded again.
“Tell me, whose cock?”
Knock, knock, knock. Knock, knock, knock.
The sound of repeated knocking on the door echoed between Ashley’s words. When Koi, realizing the sound belatedly, turned his eyes toward the door, Ashley immediately called his name.
“Koi, answer me. I’m asking you.”
Tell me that my cock feels good.
Eventually, Ashley ground his teeth and pressed him harshly, but Koi’s attention had already flown elsewhere.
“We’ve… done it a lot…”
Koi opened his mouth hesitantly.
“If we’ve done it this much, please stop now…”
A lot? We’ve only done it three times.
To be precise, two and a half. He hadn’t even properly enjoyed the afterglow of the ejaculation, and it’s over? Who decided that.
