Chapter Text
There were two secrets Yamazaki Sousuke vowed to never tell Rin.
Sousuke retreated to his dorm room, locking the door behind him. Even though he knew his roommate wouldn’t be back tonight, the protective action became a habit whenever he planned to expose his brace. With a sigh, Sousuke sat down at his desk and peeled the shoulder brace that had been discreetly hidden under a layer of shirt and jacket off. The skin underneath was an unhealthy shade of pink. He mused at its resemblance to undercooked meat, which kindled the thought of him slowly becoming shark bait. That wouldn’t be so bad.
Mundanely, Sousuke searched for the muscle cream inside the desk drawer and massaged a careful mass on the damaged shoulder. He winced at the tender pain.
The first secret would make Rin cry.
As stubborn as the teenage boy was, Sousuke learned to know his limit. Perhaps he should convince Rin to swim the individual butterfly for him during preliminaries next week.
Nursing his injury had become so much of a chore that the pity and punishment he had once imprisoned himself in naturally began to dissolve, but not without the earnest resolve to recover as well.
When Sousuke first heard that Rin was back in town, the spark he’d lost was ignited again. If he couldn’t be Rin’s rival, at the very least, Sousuke wanted to be someone who could understand what it meant to swim alongside his best friend. As a team. It became one of his last whims before he would see Rin take the gold medal on screen.
The other selfish desire was was to protect Rin’s dream, which meant eliminating anyone who was in Rin’s way. Sousuke thought of the one person he had in mind. In resentment, and cold jealousy, he pushed the boy’s stale face out of his head, replacing it with the redhead’s. His hand had deserted his shoulder and found itself dangerously lower than he intended. It was a good thing he’d locked the door.
Sousuke paused, trying to search for reason - anything, no matter how small - but soon gave in to lust and frustration when he failed to seize one. There was no need to coax and tease himself when he had already become so large. All the blood in him rushed to his lower parts. His sparsely cream-smeared hand made the sensation feel raw and organic. The hand that carried the injured arm gripped the edge of his desk. He pumped himself stronger and faster until the image in his head changed into something viperous.
Rin was under him, his face distorted into emotions Sousuke couldn’t discern. One hand jailed his best friend’s hands above his head, the other supported his back as Sousuke forced himself into the other.
“Ah!”
His partner relished in pain and something else. With tears cornering Rin’s beautiful eyes, Sousuke leaned down to - he stopped. He abandoned what he coveted.
“I’m sorry.”
But this Rin didn’t want to accept the apology. Instead, the Rin struggled out of his restraints and braced Sousuke’s shoulders, his arms and gravity again enclosing the space between them. The boy underneath beaded sweats of pleasure as hips, legs, and skin rarely unmasked encountered each other. The ache in Sousuke’s injury grew - perhaps from the imaginary Rin’s force, or perhaps from his own.
Ghostly whispers of desire filled the room. Even so, the image was so wrong. His best friend didn’t belong in his chains.
Sousuke opened his eyes. He let the bright room blind him.The pleasure only lasted a few seconds before guilt and shame drowned him to his fingertips. He hung his head back.
The second, would ruin Rin.
