Work Text:

Shawn huffed, turning over onto his other side. He ripped the blankets off his legs, feeling the cool air from the room. When he glanced up at the clock, it read 3:27 AM. He groaned softly, wiping a hand down his face. He hated when he got like this, when he’d stay up for days on end. He never wanted to, but something would tip his excitable brain off and get it stuck on loop. For all the benefits of his eidetic memory, this was certainly one of its downsides.

Giving up on being able to fall asleep, he threw the covers off himself and hauled out of bed. He padded into the bathroom. Shawn stretched, splashed some water on his face, and looked at his reflection. His eyebags were heavy, weighing down his features. His stubble had grown in, scratching his hand as he rubbed it. He looked, for lack of a better word, like shit. 

The case he was working on currently swirled around his mind. All the physical evidence pointed to a suicide, but Shawn was sure it was just a cover for a murder. His mind raced as he tried to think of people of interest, someone who might have motive to frame a suicide. There was no money, power, or property to be gained from the victim’s death. No one seemed to have opinions on the victim, much less murderous rage or revenge. He’d been running himself ragged all day trying to find something, any clue that would tip off the true culprit. 

Something didn’t fit. It was driving Shawn crazy that he couldn’t figure out what it was. Two days of investigating and they have nothing.

He groaned under his breath, moving to finish his business and sluggishly walk back to his bed. Shawn’s weight made the bedframe creak as he plopped down, exhausted. He shut his eyes, willing to stop his brain from running. He tried to think of sheep, Gus’ bald head, the churro guy, anything that would take his mind off of the case’s facts. 

No matter what he tried to do, his brain just wouldn’t stop and instead worked harder. Images flashed in front of his eyes, garbled conversations he’d had earlier in the day ringing in his ears. He felt dizzy, and all he wanted was just to go to sleep. Shawn cried out in frustration, headache quickly growing. 

He sits up, moving into the front room. He winces a bit, adjusting to a light he’d just turned on, and reaches for his coat. His sneakers are shoved onto his feet, and before he knows it he has his keys in hand, locking up his place. His motorcycle is parked outside his apartment, quickly starting up.

~~~

Gus wakes up, heart immediately racing as he’s flooded with adrenaline. A creak of his bedroom door woke him up, and he flips over to see who (or what) has opened the door. He lets out a small whimper when he sees a dark figure in his doorway, illuminated by a hallway light behind him. He quickly reaches over to his nightstand and grabs the first thing he touches as protection.

His hands close around his alarm clock, and Gus grips it tightly, preparing to make his move. He lets out a yell, clamoring out of bed towards the intruder. The man takes a step back into the light, holding his hands up in surrender.

Gus relaxes, holding a hand over his racing heart. “Shawn, man, what are you doing here? You could’ve just knocked, you know. One of these days you’re going to kill me doing this.” He feels a bit silly, holding an alarm clock and standing just in his boxers. 

“S-sorry Gus,” Shawn mumbles, a bit like a scolded child. He doesn’t make eye contact with his friend, shifting on his feet. “I need your help, dude. I really can’t sleep. I-it’s this case, I can’t get it out of my mind.”

Once Gus has calmed down a bit, taken a breath and woken up fully, his eyebrows crease. He sees Shawn’s face, taking in the weariness on his friend’s expression. His hair was unkept, jeans and t-shirt laying crooked on his body, and stubble on his cheeks. Most of his remaining anger melted away, understanding the situation. While he didn’t agree with the way that Shawn went about asking for his help, Gus is mainly happy that he came to him. It wouldn’t be the first or the last time, and at least Gus knows what to do about it.

Gus nodded, gesturing for Shawn to come into the bedroom. Shawn gave him a small smile, quickly clamoring into Gus’ side of the bed. Gus smiled to himself and groaned, pushing Shawn over to the other side and climbing back under the covers.

It wasn’t something they talked about, really. Shawn was always the more sporadic one, riding highs and lows while Gus tried his best to be consistent. When he faced those lows, he came to Gus for help. It had been the pattern of their entire friendship.

It had started when Shawn first came back to Santa Barbara. Shawn had had fits of insomnia all his life, but the episodes had increased in frequency since then. It was the beginning of Psych, the old story of Scary Sherry come back to haunt them. Shawn hadn’t slept for three days, running purely on instinct and caffeine. 

Gus had known something was off, but didn’t bring it up. Shawn was still new back to the city, and Gus was still afraid any little movement would send him running again. Luckily, he didn’t have to wait long until Shawn came to him.

He had snuck into Gus’ apartment, something that shouldn’t have been surprising to his oldest friend. He had managed to get all the way into Gus’ bed before waking the other, really giving Gus a heart attack. 

“Shawn, that had better be you,” Gus whispers angrily, once his heart rate is back to normal.

“Gus,” Shawn had whispered back into the dark. “Just ignore me. I haven’t been sleeping the past couple of days and I’m desperate, man.”

Gus had shifted to face his friend, watching all-too familiar stress lines develop on Shawn’s expression. Shawn had looked so tired, so needy, that it broke Gus’ heart. He thought for a moment, finally sighing and beckoning Shawn closer into his arms. Shawn slotted in perfectly, his back against Gus’ chest.

Just like that first time, Shawn was soon resting against Gus’ chest. His head lay right over Gus’ heartbeat, trying to focus on the steady thumping. Gus curled his arms around Shawn, holding him close. He tried to ignore the way Shawn’s breath ghosted over his stomach, the way his hair scratched at Gus’ skin.

Tried to ignore his body’s reaction to the close proximity.

As difficult as that already was, Shawn made that job infinitely harder, squirming and readjusting himself in the bed. Every once in a while, he would mumble something about the case to himself. Gus had known him long enough to tell when he was getting antsy, frustrated at not being able to fall asleep. His hand drooped down to Shawn’s back, rubbing circles absentmindedly. 

Gus wasn’t sure how much time had passed, not daring to move lest he disturb Shawn. Both of them pretended to rest, both knowing the other was still awake.

“C-can we?” Shawn asked quietly, breaking the silence. Gus didn’t need any further explanation, turning to face the other man.

“If it’ll help you sleep,” Gus replied, trying to hide his interest. “How do you want to do this?”

Shawn turned his head, making eye contact. “Can I suck you off?”

Gus sucks in a breath, nodding quietly. He can practically see Shawn’s smirk in the dark, his hand wandering down to the waistband of Gus’ underwear. His hand dips inside, grabbing Gus’ half-hard length. Shawn earns himself a groan, slowly jerking Gus off.

Gus’ breathing deepens as he gets fully erect. He’s not much of a talker in bed, but Shawn loves squeezing any little noise he can out of him. Once Shawn is satisfied with how hard his friend is, he throws the blankets off of them and pulls Gus out of his underwear. 

Shawn moves down Gus’ body, planting himself so he’s eye to eye with a hard cock. Gus is staring at him, lust blowing his pupils open. Shawn gives a little kitten lick, tasting the pre cum that has beaded at the tip. The salt on his tongue helps keep him in reality, keeping his thoughts at bay.

He slowly takes Gus into his mouth, Gus groaning at the wet heat. On the first pass, he goes about halfway down, wrapping his hand around the rest of Gus’ length. With each bob of his head, he goes deeper, the head hitting the back of his throat.

Gus lets out another low noise, his hands tangling in Shawn’s hair. His hands guide Shawn’s head, pushing him to take more and more into his mouth. Drool drips down Shawn’s chin, mixing with the steady stream of precum leaking out of Gus.

Shawn finally takes all of it, Gus’ cock bulging his throat. He sees Gus throw his head back, grip tightening in his hair. “God, Shawn,” Gus mutters, using his sex voice.

Those words shoot right down to his groin, getting him fully hard. Shawn reaches down, rubbing himself over his pants. He hums around Gus’ cock, earning himself another groan.

Shawn rubs himself, practically humping his own hand, as he continues to suck off Gus. He can tell Gus is getting close, noticing the change in his breathing. He feels Gus’ hand tighten again in his hair, pulling him off of his cock. “Don’t want to cum just yet,” Gus admits, voice strung tight. “Feeling any better?”

Shawn licks his lips, frowning slightly. Thoughts of the case still swirled around, distracting him momentarily. “No,” he mutters, voice grainy. “Can you just fuck me already?”

“With pleasure,” Gus replies, his voice low and silky. “Lay back and put your legs up.”

Shawn obeys, stripping off his clothes and exposing himself. His own cock is rock hard, twitching as it drools on his stomach. “Need you inside me so bad, Gus,” He whispers like a prayer, bucking his hips shallowly. His gut is red hot with anticipation.

Gus grabs a small container of lube from his bedside drawer, the one he’d bought for this very occasion. “I’m gonna open you up now, Shawn. Just relax, let me do the work.”

“Well I haven’t got all da- oh.” Shawn is cut off by a finger sliding past his entrance, filling him up. He tosses his head back, Gus’ finger exploring inside of him. A second finger soon finds its home next to the first, and Shawn tries not to moan as he’s scissored open.

Shawn drags his head back up, looking down at Gus. He notices that Gus’ eyes are already on him, watching his expression for any pain or discomfort. They keep eye contact as Gus slides a third finger in, and Shawn can’t hold back his moans any longer.

“Oh fuck Gus- forgot how good you were with your fingers, oh shit right there-” Gus gives Shawn an evil smirk, pressing on his prostate again. Shawn’s dick and stomach are a mess, covered in his precum. 

“I-I’ve gotta be open enough, Gus. Please just put it in already,” Shawn borderline begs, spreading his legs wider as if that would help convince the other man. “Need you inside me.”

Gus frowns, slowing his movements. “Are you sure, Shawn? I don’t want to hurt you.”

“Hurt me? Gus, please, don’t give yourself that much credit.” Shawn teased, “Besides, who’s to say I don’t like a little rough play?” His trademark smirk rested on his face, even with Gus’ fingers inside him.

Gus’ expression flattened, pulling his fingers abruptly out of Shawn’s ass. He puts some lube on his cock, rubbing his hand up and down himself. Shawn can’t keep his eyes off of his friend’s erection, practically drooling at the sight.

“Don’t say I didn’t warn you, Shawn,” Gus says, lining himself up with Shawn’s loosened hole. Shawn gasps, forgetting how big Gus really was. A shiver of excitement runs up Shawn’s spine, the need inside him controlling his mouth.

“Just fuck me stupid, Gus.” Shawn says, moaning as Gus starts to push in. Shawn grabs his legs, spreading them wider as Gus pushes in deeper and deeper. Shawn’s eyes glaze over as he’s stuffed full, their hips touching as Gus bottoms out. Bolts of pain strike up his back, not stretched enough to take all of Gus, but Shawn ignores them.

At least the noise in his brain is starting to go away. He breathes heavily, letting himself adjust to the stretch as his cock dribbles all over himself.

“Move,” Shawn whispers, more of a prayer than a request. “Please, Gus.”

Gus doesn’t need any more encouragement than that, slowly pulling out to the head and pushing back in. “Fuck, Shawn, you’re so tight.” Shawn whimpers, feeling the pain and pleasure get crossed on their way up to his brain.

He’s slow and gentle, carefully watching Shawn. The man looks absolutely wrecked, grunting lowly each time Gus bottoms out. If Gus squints, he can see the little bump in Shawn’s stomach with each thrust, proving how deep he was inside Shawn. Slowly, Shawn opens up for him, stretching to accommodate Gus’ size.

“I-is that all you’ve got?” Shawn teases again. He wants more, needs more, and he knows Gus can deliver. His head is still half occupied with the case, and he’s tired of thinking about it. Gus needs to start pounding him into the mattress, like now.

Gus recognizes the challenge, picking up his pace. Shawn moans, reaching down to touch himself. He yelps when Gus slaps his hand, denying him. He whines, but obediently puts his hands behind his head. Gus’ hands go to his hips, holding him down to the mattress.

Shawn’s eyes roll back, moaning louder when Gus finds his prostate. Gus changes his angle, aiming for that spot over and over. “F-fuck, oh my god Gus-

“Not such a smart alec now, huh?” Gus smirks, hitting his prostate harder and faster with each hit. He’s starting to lose his grip, unsure how long he’s going to be able to hold off his own orgasm. He needs Shawn to come first, and wraps his hand around Shawn’s ignored cock. He gives an experimental jerk, watching his friend fall apart.

“Nghhhh…” Shawn replies, going limp in pleasure. His eyes roll back, letting Gus use his body like a toy. “G-gus…keep going-” 

“Anything going on in that pretty head of yours?” Gus teases, knowing that look on Shawn’s face. He’s practically drooling, eyebrows furrowing as he tries to concentrate on anything but the huge cock in his ass.

“Uhm, uhm…f-fuck oh my god…n-need to cum Gus. S-so close,” Shawn stutters out, face flushed and cock leaking. “Please, please, please.” 

“That’s what I thought,” Gus nods, knowing Shawn was thoroughly distracted. He groans, hips aching as he thrust inside of Shawn as fast as he could. His hand flies over Shawn’s cock, desperate to bring him to orgasm. “Cum for me, Shawn.”

Shawn cries out, grabbing Gus’ arms for stability as he cums all over his hands and stomach. He tightens up around Gus, and a few thrusts later, he’s painting Shawn’s insides white. He gives another shallow thrust, collapsing onto Shawn. The other man gives a small grunt, but otherwise doesn’t protest.

“Oh wow,” Shawn mutters, a few minutes later once they’ve both caught their breath. “You’re amazing, Gus.”

Gus doesn’t miss the yawn that comes out of Shawn’s mouth, the way his eyes are slipping closed. He presses a gentle kiss to the other man’s forehead, pulling himself out of Shawn. “So are you, Shawn.”

Shawn whimpers at the loss of contact as Gus rolls off. “Wait here,” Gus commands, earning a tired thumbs up from his friend. He climbs out of the bed, leaving Shawn on the bed.

Gus heads into the bathroom, grabbing two washcloths and wetting them. He cleans himself up with one, grabbing a pair of underwear from the laundry basket. He puts them on, taking the other damp washcloth to the bedroom. He walks in, finding Shawn passed out over the covers, drying cum still on his body.

Gus smiles, affection blossoming in his chest. He gently wipes Shawn up as best as he can, prioritizing keeping the man asleep. He throws a blanket over the man, sliding in next to him. Gus’ eyes slide closed, drifting off to the steady rhythm of Shawn’s breathing.

~~~

“Gus, I figured it out!” Shawn runs out of the bedroom, dressed in some of Gus’ clothes. “The handwriting, Gus, we didn’t check the handwriting!”

Gus is sitting in his kitchen, slowly eating a bowl of cereal. He startles, spilling a bit of milk on his shirt. He frowns, turning to face the other man.

“Good morning to you too, Shawn,” Gus mutters, cleaning himself up. “What handwriting did we forget to check?”

Shawn bounces on his feet. “The note! I knew it couldn’t have been written by the victim! Come on, let’s go.” He walks over to Gus, lightly tugging on his arm as if to hurry him up.

“Shawn-” Gus tries, only to be cut off by the press of Shawn’s lips to his own.

“Thanks for your help last night,” Shawn whispers as he pulls away. He winks, turning to grab his keys. Gus sighs, quickly finishing his meal and hurrying after his best friend.
