Perfect Pair (RIREN/ERERI- Omegaverse! Au)

chapter two- Levi's affection

Eren had fell asleep long ago, leaving me alone with Erwin. His snickering pulled me from my work and engaged me in meaningless conversation.
"What is it?" I hissed venomously, "Never mind, I just want to get this over and done with." His obnoxious noises continued throughout his visit but stopped as Arik cried out for attention.
"I-I'll get him..." Eren tiredly wandered out of our room, like a zombie, towards Arik's.
"Stop Eren," I hugged him sweetly, "Go back to bed, I'll check on Arik." Eren's weary eyes lit up before he turned on his heal and began heading to the room.
"Please hurry up with your business and come to bed, I'm lonely." That was the last thing Eren said that night; Erwin and I finished our work by daylight. Finally a Sunday with my family away from work, having fun alone.
"Please let me see Arik!" Erwin begged as Eren brought the small cub into the living room for his breakfast, "Please! He's so cute!" I growled deeply under my breath, alerting him to my anger.
"It's fine Levi," Eren slipped Arik's small nimble body into Erwin's, "Please be careful." Erwin smiled down at my child with an admiring gaze, peering over at Eren as he compared he two.
"I wish I had a baby! They're so cute!" Erwin snuggled Arik, "Levi is so lucky to have a wife like you!"
"We... We aren't married..." Eren nervously rubbed the back of his neck, retrieving our child from the strangers arms.
"So how was Arik conceived?" I knew what he wanted to hear- that Arik was the result of an omegas heat and that I was the first alpha on the scene. I felt disgusted by what he was implying.
"Arik was conceived properly! Like every other fucking child out there, not when I was at my worst!" I hated what we were but at the same time accepted it because without Eren being an omega, we would have no future together. Arik had a long time before he was to be sorted into the hierarchy of our society, I only prayed he was an alpha.

"I know you weren't happy about what Erwin said and I understand," Eren appeared angry unlike usual, "I wanted to punch him right there!" He used to be violent, masochistic and free but later gave up that life to become a mother.
"Eren," I whispered, "We haven't... had sex... in a while, Arik's asleep so..." it seemed Eren knew what was going to happen. After putting Arik back to bed, we began kissing passionately in the bed room. I shoved Eren forcefully, by accident, onto the mattress. Eren removed his clothes willingly; I ripped away my clothing like it was nothing. Eren was had his face towards the bed and his back facing me. My body didn't want to to stop as I instantly began thrusting inside his slippery wet entrance as it begged to be filled. As much as I wanted to sink my teeth into his clear nape, I stopped myself instead and kissed it gently. My hand made its was up Eren's stomach and chest to begin playing with his nipples.
"W-Wait Levi... stop!" I panicked instantly but couldn't pull out due to the tightness, struggling to fight my lust against my concern.
"What?! Have I hurt you?!"
"N-No..." I could see he was red to the ears, "I'm... my nipples are... well, I'm kinda... lactating a little..." then I noticed it- the small amount of breast milk dripping down my fingers and into my palm. Using my other hand, I flipped him over and grinned as I licked away the fluid. He showed showed a face of horror and embarrassment before lightly punching my arm. "You're disgusting! Now I'm never gonna be able to feed Arik again without imagining this..."
"I drink anything that comes from you," I hummed as I started to thrust into him deeply once more, "So your milk is bad but your sperm is okay?" He didn't answer, signaling defeat. This is why I love him...
