Armin looked up at Hange, nervously waiting for her answer.
"So, it looks like you're good to go," She grinned, "Please him well." Armin blushed profusely as they continued walking. They had reached the hallway and Hange stopped, allowing Armin some space. The young Omega glanced back over his shoulder, glancing at Hange with a timid look.
"Are you sure that it's alright?" He asked, eyes nervously flickering back to the massive door that stood in front of him.
"Yes. I am sure now hurry up and get that Alpha dick." She laughed with a wink. She waved him on, shooting him a reassuring smile. Armin knew she wouldn't let him do this if she wasn't a hundred percent sure that it was safe. The baby he carried was the only thing he could attach his hope to. If he lost it, he didn't think he would be able bounce back like the last one.
He took in a sharp breath, yanking the large door open. His Alpha was sitting at the desk, head in his hands, dozens of papers littering the surface. Armin felt himself smile as he waddled over, arms resting on his Alpha's shoulders. His scent calmed Armin down, the familiarity and calming nature soothing his tensed muscles.
"Erwin," He nagged, gently rubbing his fingers into Erwin's shoulder muscles, "You're working too hard again." The Alpha sighed back into Armin's touch and kissed his hand gingerly.
"Sorry, I just have so much to do and I haven't been able to meet you. I missed you." Erwin stated with a small smile. Armin lips spread into a wicked smile as he felt his cock twitch in arousal. He slid into the Alpha's lap, mindful of his stomach and grinded his ass down against his crotch.
"What are you doing?" Erwin questioned, watching Armin with lust filled eyes.
"Well, you had a rough day and I've been incredibly horny waiting for you." Armin grinned, feeling the bugle grow larger at his words.
"Naughty," Erwin smiled, before his hands dropped down to stroke Armin's swollen stomach, "Is it safe?"
"Hange said it was okay." He answered, leaning into to capture his lips in a quick kiss. Erwin didn't break the kiss as he hooked his forearms around Armin's thighs and hoisted him in the air. The Alpha placed him gently on the bed, lips unlocking from Armin's and began to travel down his neck. His tongue glided past the bond mark they shared, causing Armin to shudder and twist his head, allowing him more access. Erwin took the extra room, greedily and began to suck, bite and lick all of Armin's neck, leaving a shit ton of bruises in his path. Armin let out small noises as Erwin continued, arms fumbling around the Alpha's waistband to pull his cock free. Erwin smiled against his neck, as Armin began to fondle his dick.
"Quite impatient today." Erwin laughed, pulling back away from Armin's neck to rub fondly at his stomach.
"Please?" Armin begged, looking up at the tall blond man with large puppy dog eyes.
"I cannot resist those," He said with a sigh, hooking his fingers on Armin's waistband and pulling down his sweatpants and underwear. Erwin shifted his body down, so his head was nestled in between Armin's thighs. He took the Omega's member in his mouth, encasing the organ in hot wet heat. His fingers travelled down to the tight ring of muscles and was pleased to find it already leaking slick. He sunk his fingers into the hole causing Armin to jerk at the intrusion and groan. He swirled his tongue around the tip of Armin's length and flicked his tongue across the slit causing the Omega to let out a loud moan. Armin arched his back into the Alpha's touch, mouth parted slightly as he inhaled sharply.
"Erwin, please," Armin begged, his finger sliding inside Erwin's shirt and up his back, nails digging into the soft flesh.
"Oh god," Armin muttered as Erwin spread his fingers apart and curl. He removed his mouth of Armin's dick, instead kissing his stomach as he removed his fingers from Armin.
"Just a little longer," Erwin whispered, reaching down to guide his own cock to align with Armin's puckered hole.
"Ready?" Erwin muttered into the shell of the Omega's ear with a smile. Armin nodded enthusiastically, hands snaking around Erwin's back. Erwin slid into Armin with a soft moan, the tight heat wrapping around his dick. He stayed still for a moment, concentrating on keeping his knot down and not spiling already and also allowing the pregnant Omega to adjust.
"Has he been treating you alright?" Erwin asked, one hand running along the curve of the swollen stomach.
"I don't think the right time to ask is with your dick up my ass." Armin muttered grumpily, silently urging Erwin to start moving. He looked up at him with a small smile, slightly swaying his hips but he knew he wouldn't move without answer.
"He has been good but recently he has begun his kicking phase," Armin replied, noting the loving smile Erwin was giving him, "Come on." He teased, pulling his lower half up slightly, then bringing it back down.
"Oh god, if you weren't carrying my child right now, the things I would do to you." Erwin growled, lowering himself to kiss Armin's soft, pale neck. He pulled out to the tip before thrusting back in, hard and fast. Armin let out a deep moan, wrapping his legs around Erwin's waist and locking his ankles together. His Alpha didn't hesitate to quickly pull out and push back in again, aiming for the spot he knew would make Armin fall apart. The young Omega pushed his body, as much as he could manage, trying to meet Erwin thrust for thrust as the all too familiar heat began to tighten in his lower abdomen.
"Fa-fast-faster," He spluttered out, his hands fisting the sheets tightly as Erwin increased his speed.
After a few more thrusts, Erwin's knot began to grow, spreading Armin's ass wider. He loved the feeling, whether he was in heat or not, and even craved it. Erwin's hands moved to rest on the Omega's plush hips, digging into the flesh as he pulled Armin's ass to be flush against Erwin's body. As the knot grew larger, Erwin's thrust slowed down considerably. The moans and grunts from both males also grew louder with the knot, filling the room alongside the sounds of flesh slapping against flesh. Armin felt his own orgasm rising, his legs twitching and the coil of heat growing tighter and tighter.
"E-E-Erwin…I-soon." The almost inaudible words spilt out of his open mouth.
"Same." Erwin stated, leaning down to capture Armin's lips in a breathless kiss. His thrusts had mellowed down to shallow ones, as his knot grew to its maximum size. With one final thrust, Erwin spilled inside Armin, hot white fluid filling him. Armin's own release followed a beat behind, his clear infertile seed shooting up to coat his and Erwin's stomachs.
"I love you," Erwin whispered as he nuzzled down into Armin's neck, still coming down from his orgasmic high. Armin smiled as his arms tightened their grip around Erwin.
"I love you too." After gathering a number of pillows, Erwin shifted Armin on his side supporting his belly with the pillows. Armin sighed contently as Erwin kissed the top of his forehead, hands protectively wrapped around the swollen stomach. Erwin's fingers travelled through Armin's hair, slowly lulling him to sleep.
When he awoke, the mates were no longer tied and his stomach was cleaned off all his fluids. A little panicked that Erwin wasn't lying beside him, Armin sat up in a hurry only to see Erwin sitting back at the desk; body hunched over paperwork. He sighed, pushing himself with struggle off the bed and draped his arms around Erwin's neck.
"You can't stay away, can you?" Armin stated, leaning over his shoulder to kiss him on the cheek. Erwin muttered something inaudible under his breath as he turned his head to place a quick kiss on Armin's lips. A sharp knock on the door interrupted their domestic bliss and Armin nodded to Erwin, before waddling towards the door. He opened it with a yank to see Hange standing there with her usual shit eating grin.
"Time to go, sweetie." Armin, as fast as he could, padded back over to Erwin, pouting at the doctor.
"Already?" He asked sadly, his arms looping around Erwin's waist.
"It's been three hours." She explained, eyes connecting with Erwin's. Armin let his arms fall from Erwin, glaring at him.
"You let me sleep that long?" His tone containing faked hurt. Erwin just gave him a loving smile and bent down to lock lips with Armin's.
"I'll bring her next time, Armin." Erwin promised, rubbing his neck along Armin's own neck, making sure he lathered the Omega in his scent.
"You better," Armin smiled. With another quick kiss, Armin left Erwin alone in the room, despite the aching in his chest.
Hange escorted him back to his room, after stopping at the canteen for dinner, and gave him and Eren their night time medication. She ignored the flipped nightstand and broken lamp, leaving Armin to deal with the obviously angry Omega.
"Eren?" Armin called out. Instead of answering Eren shifted himself so he was facing the corner, back towards Armin.
"Are you okay?" He padded over, touching Eren's shoulder gingerly but the brunette shrugged him off.
"How many times do I have to get pregnant?" Eren hissed suddenly, catching Armin off guard.
"What?" He asked, seating himself on the end of Eren's bed.
"How many fucking kids do I have to have before I can leave?" Eren hissed again, pulling his legs tighter to his chest, hands balling up into fists.
"Three." Armin replied, subtly shifting his body closer.
"Where do they go?" The anger in his voice lessened, mixing in with another emotion Armin had yet to distinguish.
"Well if you have a mate, they can live with them or you can put them in a foster care and live with them when you leave. Last option is just putting them up for adoption." Armin answered, his own hands subconsciously running over his own stomach. The baby gave him a light kick in response.
Still here, mum.
"But- "Eren's voice broke off and a sob replaced his words. Armin couldn't help his instincts and he pushed himself forward, wrapping his arms around the crying Omega. Armin let out soft 'shhs' as he calmed Eren down.
"It is a lot to take in and its only your first day," Eren turned around, face-to-face with the blond Omega and he buried his face into Armin's shoulder, "Plus your hormones are all over the place. Once you have an Alpha it will all become much easier."
"Where am I supposed to get one of those?" Eren cried, his voice muffled by the fabric.
"The facility is also a place for Alphas to choose mates, you know." Armin laughed lightly, brushing a strand of Eren's hair behind his ear, "You're such an attractive Omega."
"I don't want to be mated or pregnant." Eren stated low enough that Armin couldn't hear. They remained in silence, Armin's mothering nature calming Eren down enough to get some sleep.
