Eren stirred from his nap, feeling sticky and gross but satisfied. His body was stiff, achy and as he tried to sit up he realised his hips were throbbing with pain. His hands drifted up to his neck, tracing the bite mark that had already begun to scab over. It wasn't supposed to be there. He wasn't supposed to be fucking mated while he was here. Just have the stupid children and get out. He was growing pissed as he turned to the side, ready to confront Levi and maybe punch him but the bed beside him was empty. He growled low in his throat and fell back onto the bed

"What the fuck are you growling about?" Levi muttered, making Eren glance up. Levi had a towel on his head, that was covering his dripping wet hair. Eren trailed his eyes down, noticing that Levi was completely naked, water droplets still repent on his skin.

"You, you fucking asshole." Eren grumbled, resting his head back on his pillow, "And put some clothes on."

Levi sighed, taking the towel off his head and folding it neatly.

"Why? Aren't we mates now?" Levi cocked his head at Eren, questionably.

"Not fucking consensually that's for sure." Eren retorted. He felt snappy but wasn't sure if it was an effect from his heat or Levi's words last night.

"I thought you said you were okay with it when I explained it?" Levi sunk down onto the bed, sitting next to Eren.

"I was kind of delirious at the time, you know." Eren huffed, burying his face into the pillow. He felt Levi's hands make their way through his hair, brushing through the strands gently. He knew he should push his hand away but it just felt so nice that he just shut his eyes and sighed into the touch.

"Have you even thought this through, Levi?" Eren questioned, "What do you plan to do with the children? What if I wanted them and you didn't? What if I planned to get rid of them and you wanted them? I'm stuck with you and you didn't even consider this." Levi's hands stop moving for a minute.

"I just thought I'd go along with whatever the Omega wanted." Levi answered, his voice low as he begun to move his hands again.

"A simple conversation beforehand would have been nice." Eren mumbled into the pillow. He felt the mattress dip behind him and felt Levi's warmth on his back.

"I should have talked to you, I know," Levi's breath was warm against Eren's neck, "I have been waiting for someone to mate for so long I just got ahead of myself."

"Isn't every Alpha jumping at the chance to fuck Omegas in heat?" Eren grumbled, feeling Levi's arms snake around his waist.

"We get forced to breed, just like Omegas. Powerful Alphas are getting kidnapped all the time." Levi explained. The Omega hummed in response still partially mad at the Alpha but he understood why he did it. He could also feel the warmness start up in his stomach again so he ended the conversation. His cock was already hard again, flush against his stomach looking for some attention. He felt Levi's hands travel lower down his body, just stopping above his cock, his fingers dancing along the skin.

"I guess we will just have to talk about this later." Levi whispered, kissing Eren's scent glands. Eren squirmed under his touches, moving his hips upwards so Levi's hands brushed against the head of his cock. Levi didn't waste time, he himself was already hard and had begun to sink his cock into Eren's slicked entrance. They both groaned as he slipped in, the heat welcoming him. Levi rocked his hips back as he nuzzled his face into the crook of Eren's neck, placing soft kisses there. He took his time reentering, making every slow and gentle. He drew out each moan from Eren, making sure he buried himself in fully before pulling out. Eren melted underneath the Alpha's skilled thrusts.

It wasn't long before Eren was cumming over the sheets of the bed, one hand hooked back in Levi's hair and the other fisting at the sheets. Levi soon followed suit after a few more thrusts, nibbling the mating mark as his knot locked them together. Levi groaned as he came, coating Eren's insides with white, hopefully hitting his womb. Eren let out a sigh as Levi's knot reached its fullness bringing him the relief that his heat made him crave. Levi was panting as he came down from his high, brushing his hair out of his eyes.

"You good, now?" Levi asked, moving his hands into Eren's hair and brushing it out of his eyes.

"This doesn't mean I forgive you for the mating thing." Eren mumbled, already feeling out of it already even though his heat had just started. Levi's soothing hands only added to his drowsiness and Eren felt a warm feeling spread through his chest. He had to admit to himself that he enjoyed Levi's presence and also his cock that was currently throbbing within him. He sighed heavily, too tired to have a lengthy discussion with himself whether he liked Levi or not instead opting to shut his eyes and let Levi trace circles into his scalp.

"How much do we get to see each other after my heat?" Eren mumbled, already half asleep.

"What do you mean? We'll be sharing a room." The Alpha replied, giving Eren a strange look, "Have they not explained all these things to you?"

"Well, Armin doesn't see his mate often so I just assumed it was all like that." Eren explained causing Levi to groan under his breath.

"They are like that because Erwin runs the facility and is not allowed to mate with an Omega here. It's against policies but he did it anyway so he needs to keep it quiet." Levi felt his knot deflate slightly, not enough to pull completely out but enough so that he could shift Eren around so he was straddling the Alpha.

"Don't explain it to me like I'm stupid." Eren grumbled. Levi looked over Eren, who had his arms crossed over his chest and was looking down at Levi angrily.

"I can take you down in a second even with my cock in your ass." Levi warned which irritated Eren even more.

"So what Mr. Alpha, are you going to make me submit like the weak Omega I am? Mate me against my will? Oh, wait you've already done that." Eren snapped, trying to remove Levi's cock within him. When it wouldn't budge he got even more frustrated and slammed his hands down roughly on Levi's chest. Levi clicked his tongue in annoyance.

"You're acting like a brat." He stated, feeling his knot continue to shrink as his annoyance grew, "These emotions are unnecessary. We are going to spend the rest of our lives together I don't think you should hate me now." Eren gave another pull and Levi's cock finally pulled out, although painfully. Eren pushed himself off the bed, his legs wobbling under his weight before he righted himself.

"Fuck you, Levi." He spat, leaving the room.
