The world is hard on an Omega...
Severus stared at Sirius.
The silence was overwhelming Sirius, he was sure he fucked up. Without noticing he started fitgeting, Severus raised a brow at him but the smiled,
"I never would have thought I'd get to see Sirius Black fidgeting because of me.", Sirius leaned back i relief, "Soooo what's your answer?", Sirius tried so seem relaxed but he wasn't sure if he could trick the Slytherin. "I thought I just imagined that! But why? Why do you want to bond with me?", now it was Severus fidgeting, Sirius found it endearing, "After what happened at your House I saw how vulnerable an unmated Omega is...we already decided to be partners and parent Draco together. I found myself thinking that I wouldn't mind, you know, being mated to you!", Severus scowled, "That's why you want to mate? I can't believe you. Two should only mate when in love. I wont mate you because of that!"
Sirius smirked knowingly, "So you only object because you think I don't like you... you didn't say you wouldn't want to mate.", Severus stood up from the couch spluttering, a light blush apearing on his face,
"No! No. I didn't...You, You're misunderstanding! Not everyones in love with you just because your handsome you arrogant arse!", Sirius slowly walked towards the Omega as if approaching a wild animal until he had Severus crowded against the dining table, "Really? But you just said you think of me as handsome and you always blush around me. Now that I think about it...you could have gone to Albus, Remus, Moody, Minerva or Lockhart but no you came to me. Why did you choose me? I think you knew I would have helped but also wanted it to be me. You like me. I just don't know for how long you have. hm?".
Severus tried to avoid Sirius eyes but he grabbed his chin turning his head. He felt like the Alpha could see his soul, he felt exposed, "Even if it was true, and I wont say it is, you don't love me so we shouldn't mate. I wont mate with unrequited feelings. Not that it's true that I feel something for you! Don't get ahead of yourself.", Sirius smirked, "Love? No one talked about love. So you love me? I feel flattered. I'm happy you return my feelings.", Severus eyes were wide as Sirius took a step back and hurled Severus over his shoulder and went to pick up Draco, "Put me down you buffon! Put me down! What are you doing?!."
After dropping Draco of in Severus bedroom, Sirius went to his own, casting a silencing charm while Severus was still kicking and complaining. He threw Severus on the bed and crawled over him. "What do you think you're doing! Let me go!", Severus face was red which made Sirius only more sure of his feelings towards him. He had always liked the Omega, only in secret of course, all the bullying was a bad excuse to hide to his feelings. He always looked for the Omega afterwards, to check if he was okay, he always felt bad but now he could maybe make everything right. James and Remus never knew about it, but now the feelings are back and he wont let this chance slip through his fingers. "Look at me Severus. Just for one moment! I have loved you for a long time and I'm sorry for all the things I did back at Hogwarts but I didn't want anyone to find out! Now that your back I want to make things right! I can see that you feel the same and I'm sorry for everything but please give us a chance! If you don't love me back then say stop and I will."
Sirius took off his jumper and opened his trousers then he began to unbutton Severus shirt he looked to Severus expression but Severus had his face turned, after no objetions came he kept going until he reached the Omegas zipper. Dainty and cold fingers stopped his and he looked back up. "What's wrong? Do you want to stop?", paniv rose in Sirius chest, "I...I'veneverdonethisbefore!", Severus kept rambling so much that he didn't notice Sirius climbing his body up until they were face to face, only when a hand was on his cheek did he see Sirius looking at him lovingly, "Well then I would be honoured to be you first and last for this life. Do you trust me?", Severus face was very warm but he nodded words failing him. In one swift motion he was naked. Severus tried to relax but he never felt more exposed under Sirius hungry grin. Sirius hand was on his face again and hus thumb began stroking his lip, "Can I kiss you?", Severus swallowed hard, "yes, you can."
Suddenly lips were on his and a hand travelled his down his body. A slicked finger found it's way to his opening and he looked at Sirius confused, when had he lubed his fingers?, but Sirius read his mind, "wandless magic.", the first finger entered him forcing a moan to escape. Sirius smirked at the pleasured face and kept adding fingers until he was sure Severus was ready to take him. "Are you ready?", Severus opned his eyes, his field of vision blurry because of the tears that had formed out of pleasure.
"hm? yeah sure.", a kiss found its way from his neck to his mouth as something breached his rim, going deeper and deeper until it hit a spot. "AaaAh, what was that? Sirus! It uuhmhm...it feels weird." Sirius sucked the skin on his neck, "It will feel good soon." Sirius kept thursting slowly, only after feeling his know swell did he go faster. Severus pressed against him, " Sirius, there is...it's to big! It hurts...make it stop.", The Alpha stroked the Omegas hair and kept whispering to him encouraging words. "I'm cumming, love. Are you ready?", the Omega smiled and nodded they came toghter as Sirius bit down on the Omegas nape marking him as his. An overwhelming feeling flowed through both of their bodies and they could feel the conection forming. Sirius layed them both down on the side so that he was big spooning Severus because they were still knotted together. After a while they fell asleep. A feeling of belonging on their mind.
