Work Text:
Eren stirred, his face scrunching up as he slowly woke and gave a big, shaky stretch. His arms fell back to the pillows once he was done, lazing in bed. One eye peaked open and he spied Reiner still sound asleep beside him, flat on his back and his head lolled to the side, softly breathing. His massive chest rose and fell gently with the peace of sleep. Eren smiled, admiring his muscular form and the hint of scruff adorning his jaw. Reiner’s chest and arms were corded with large, thick muscle, making him a mountainous heap under the thin blanket. As his eyes traveled downward, he noted the strong outline of his massive thighs, and even more so, the lazily half-mast morning wood between them, tenting the sheet.
Eren’s mouth watered looking at it, tempted with its girth and shape. Deciding to have some fun, he slowly pulled the sheet back, causing Reiner to hum and shift, frowning, but the man did not wake. Since both of them slept naked that night, not to be bothered with clothes after fucking, Reiner’s lower half was bare and inviting.
Reiner’s cock was lovely. The tip obscured by foreskin and curved over under its weight. It jutted proudly between Reiner’s legs, his large balls hanging low underneath it. Slowly, Eren crawled between his spread legs, leaning forward to ghost his breath over the erection. It gave an interested twitch, bobbing and coming to stand slightly taller, some of the skin pulling down to expose a peek of the head underneath. He chuckled lightly to himself; so sensitive.
With great care, he brought the tip into his hot mouth, taking his time to suckle at it and massage his tongue into the extra skin, swirling and worshiping the small bit of cock, rolling over it with his tongue. Reiner groaned above him, long and pleasured. Glancing up, Eren made sure he was still asleep as he gripped the hard shaft in one of his hands, holding it in place as he began to bob. It grew larger and harder under his attentions, developing into a full, flushed erection.
Eren loved sucking that cock. It was one of his favorite things to do. Making Reiner come undone underneath him and lavishing attention on his boyfriend was bliss. And he knew Reiner loved being woken up with a good blow job, which worked well for Eren — he do anything for him.
In his sleep, Reiner’s hips chased the stimulation, slightly thrusting his hips into Eren’s mouth as he worked up and down that beautiful cock. The head brushed against the back of his throat, to which he relaxed and opened up to let it sink further in, slowly bringing his lips down to the base and planting his nose into the dark blond curls. Reiner moaned loudly. The full, hot erection was sheathed in Eren’s warm, wet mouth. Drool escaped the sides of his lips as he held himself in place, carefully swallowing around the massive intrusion and warming it inside of his fucked out throat. Reiner gave a breathy pant, rolling his hips into Eren’s face. Finally, Eren’s gag reflex triggered, unable to take the cock any further and slid it out of his throat, coughing. He still kept Reiner warm and wet, massaging his tongue around the portion inside his mouth, opting to jerk off what couldn't fit inside at the moment.
“Eren…” Reiner sleepily groaned, a large hand coming up to cup the back of his head. Eren gave a hum of acknowledgement, the vibration going straight to the cock in his mouth. Giving a hiss of pleasure, Reiner instinctively pushed his head down between his legs, moaning again as Eren obediently took him in his throat once more.
“Oh… Shit, ‘ren.” Reiner moaned, waking up slowly, “that’s good. That’s so good, baby — fuck .” The hand on his head threaded into his hair, tightening into a sharp fist. His bleary eyes opened and he guided Eren’s head with a firm hold of his hair. Eren hummed happily and let his boyfriend guide his head up and down the shaft, letting him set the pace. His jaw was splayed open and perfect, making for a sloppy, well-given blowjob; just the right amount of pressure and tongue for Reiner to fuck into.
Reiner held Eren’s head in place for a moment, digging his heels into the mattress to fuck into his stationary mouth, using him like a hole. Eren loved every minute of it. If there was one thing he could never get enough of was choking on Reiner’s cock. He took great pride in his ability to hold back his gags and give his boyfriend the ultimate pleasure he could offer.
After a few deep thrusts, Eren started to get a little light headed, needing air. A few quick taps to Reiner’s thigh was all it took to get the blond to immediately release him. Eren pulled back and gasped for air, panting hotly over the spit-slicked cock. Reiner lovingly stroked his hair, brushing shaggy bangs back from his lightly sweating forehead. He gripped himself and rubbed the flushed swollen head of his cock around Eren’s lips, coating them with spit and precum.
“How long were you going down on me before I woke up?” He laughed lightly, as Eren caught his breath. “You love this cock so much you can’t even wait?”
Eren grinned at him, devilishly darting his tongue out to lap at the tip of Reiner’s offered cock.
“Wanted to treat you,” he rasped, his throat raw, “You’re supposed to lay back and enjoy it, so shoo.” He flapped a hand at Reiner’s, chasing it away and replacing it with his own. Reiner chuckled and settled back into the sheets, propping himself up so he could watch the show between his legs.
Eren guided him back into his mouth, resuming his earlier enthusiasm and sucking diligently at all the right places. When he gave a particular firm squeeze to the base and hollowed his cheeks, Reiner’s head fell back into the pillows with a soft thud.
“God, yes, that’s it,” he panted, circling his hips and fucking up into Eren’s pliant mouth. “You were born to suck this dick, weren’t you?”
Eren deepthroated him again in response, a wicked glint in his eye.
“Fuck, ‘m not gonna last if you keep doing that…”
That only seemed to speed Eren up more. He eagerly held himself low on Reiner’s cock, fucking it deep into his throat before pulling back shortly and repeating, milking him well and good now. Reiner’s thighs started to tremble, a hiss escaping between his clenched teeth. Eren’s eyes were shut tight now, ignoring all discomfort and throwing himself wholly into finishing Reiner off. Should he have looked up, he would have seen Reiner’s face contorted in mind-blowing pleasure, his own eyes squeezed shut and his head thrown back against the pillows.
“Ah! Ah — ‘ren, baby…. Coming, coming!” He whispered, body going taunt and finally spilling down that warm, soft throat. Eren groaned with him, slowing and working his mouth up and down the flushed shaft lazily, helping Reiner through his orgasm. Warm, salty seed pooled in his mouth and down his throat, a little bit escaping from his lips and dripping down the sides of Reiner’s cock to make a mess. Reiner gave a heavy sigh when he was done, sagging back into the pillows, completely spent. Eren pulled off of him to proudly oversee the aftermath of his work.
He swallowed down his mouthful, smirking as he caught Reiner staring at his bobbing throat with hunger. Even fully satiated, his boyfriend still looked at him like he wanted to fuck him into the mattress. Still raring to go himself, Eren devilishly lowered himself between Reiner’s spread legs and tongued up and down the shaft, getting everything he missed and cleaning up the mess. Reiner huffed in sensitivity, but let him do as he pleased, his legs left obediently spread.
Eren finished off with a swirl to the tip and popped off, staring heatedly into Reiner’s eyes.
“C’mere,” the blond ordered, letting Eren crawl up his body and rolling them to their sides. “Your turn.” He grinned.
