August 2025 R18 scene: Demian x Izumi.

Couple: Demian x Izumi (The Violinist and the Nerd).

Canon? Yes, it happens right after the end of episode 4 of season 3.

----------------------

Demian pressed Izumi's body against the mattress as his lips kissed him and his hands hungrily roamed over him trying to get rid of his clothes. Despite the urge, Demian always tried to undress Izumi with some gentleness to make him comfortable.

Just a few moments ago, they had had an absurd conversation that Demian regretted. Why had he become jealous over strangers that Izumi didn't even like? Perhaps, deep in his heart, Demian still remembered how he felt when he considered the possibility that Izumi was going to leave him for Eiji. It had all been a horrible misunderstanding that Demian didn't want to give a second of his time to again, but he had and now he just wanted to erase those thoughts in his boyfriend's arms.

Demian pressed his thigh against Izumi's crotch and watched him blush with the devotion he always looked at him with in intimate moments. They had made love a thousand times in each and every spot of that flat, but Demian was still going crazy with the first moan that indicated he had succeeded in turning him on and wanted more.

He would give him more. He would give him everything.

Demian finished undressing him between kisses, revealing his erect member that he was still pressing and stroking with his thigh, forcing Izumi to spread his legs.

He held both of Izumi's hands against the pillow above his head, and dropped his free hand to his erection to offer him relief.

"Ah… Ah…"

Izumi moaned softly, his eyes fixed on Demian's skillful hand and the friction it exerted on his cock from root to tip. Up and down, rhythmic like the beating of a heart.

"Do you like it?" asked Demian in barely a whisper. Pleasuring him like that while he had him pinned down and at his mercy was killing what sanity he had left.

"Y-yes... Nh..." replied Izumi finally looking up to meet Demian's gaze. If he could have put the world on pause, Demian would have frozen that image. Too sensual, too beautiful.

Izumi, who had so far pressed his legs against Demian's thigh, spread them wider, inviting him to invade that area of his body.

Demian took lube from the bedside table and played with his fingers inside Izumi, soaking in the space and preparing his muscles to embrace his member without pain. Izumi squeezed his eyes shut, letting himself be explored.

When he felt Izumi's body respond satisfactorily, Demian released him and proceeded to unbutton his trousers hurriedly and awkwardly. Izumi bit his lip and Demian swallowed saliva so hard he felt he would choke.

He positioned himself between his legs, resting his body weight on his hands on either side of Izumi's head as Izumi adjusted his position so Demian could penetrate him.

He did not wait.

The first thrust drew an audible groan from his partner. The second made him arch his back and clench his fists against the sheets. On the third Demian simply lost control. His hips began to slam into Izumi's body, losing count and gasping in pleasure.

He kissed his forehead, his eyelids, his nose... Izumi vibrated to Demian's rhythm, soft and fragile at his mercy.

Demian squeezed his eyes shut, letting his most primal instincts take over. He opened them again when Izumi's hands cupped his face.

"Ah... Ah... You're..." Izumi swallowed, struggling to finish the sentence between pleasurable moans. "The only one..."

The only one he had allowed to get close enough to let his heart be biten and allow his body to be conquered.

The only one he would let see his most vulnerable sides.

The only one.

Demian smiled, pressing his forehead to Izumi's.

"I love you," he whispered, and his mind repeated it like an echo, an endless echo as their bodies melted into one.

The rhythm increased until it finally became spasms, choked cries and wet bodies. Demian was the first to orgasm, but it didn't take long for Izumi to relieve his own tension.

He lay beside him, looking at him with his cheeks flushed from the effort and his throat still full of sighs. He ran his thumb over his lip before kissing him calmly and sleepily.

"I like it when you kiss me like that," Izumi whispered, barely inaudible.

Demian pulled him into his arms, taking advantage of the angle to scatter kisses through his hair.

"Go to sleep, tomorrow will be another day," Demian told him with a little smile. "Another day in which I plan to kiss you again in as many ways as I can think of."

A few minutes passed in which Izumi didn't say anything, to the point that Demian thought maybe he had already fallen asleep.

But then Izumi raised his head to meet his eyes.

"It's 00:00 already, it's another day," he said, leaving Demian confused and perplexed.

"...Kiss me?"

Demian let out a small laugh, but Izumi waited stoically.

"You're too much," Demian told him, amused.

"Too much wh-?"

But Izumi couldn't finish the sentence. Demian's lips caught his to slowly palpate them, soaking in his taste.

Izumi smiled before kissing him back, clinging to him with arms and legs.

As the city fell prey to sleep, they kept their love awake for a little while longer.
