Chapter 13:

A short while after leaving the house they rounded the corner and Reg took off running when he saw the opening of the park. Sirius kept his pace knowing his son was safe once he saw him run into park area, the wards around the place prevented kids from getting hurt or taken. That was one reason he came here, always afraid that James would figure out who Reg was and try to take him away. When he entered the park area he looked around and felt like running when he saw Severus walking up to him. He stood his ground however and looked away from the other man to see his son running around with the other kids.

"Hello Sirius." Severus greated as he walked closer to him.

"Severus. Glad you could make it." He smiled and felt his heart melting when he saw the other man smile back.

"Regulus seems to be having the time of his little life." Severus stated as he looked over at the boy now playing tag.

"He loves this park. He's made some great little friends here." Sirius stated as he continued to watch the little boy laughing.

Sirius found himself backing up and sitting on the bench they were standing in front of and held his breath as Severus sat right next to him, not leaving any space between them. They sat in silence for a while as they just watch Reg run around and have fun. Sirius couldn't help but think of all the things the three of them could have done together if it had worked out back in school.

"Is everything alright Sirius?" He heard Severus ask as he placed a hand on his knee. He jumped right up and walked over to where his son was now sitting laughing with some other kids.

"Reg can you come here a minute. I have a friend I want you to meet." He stated seeing his son jump up and smile at him.

"Sure Papa." He responded as he grabbed the hand offered and followed Sirius.

"Son you may know Dr. Snape. What you didn't know is that we were friends in school together. I just wanted you to meet him because he will probably be around alot more." Sirius said to his son who was peeking from behind his leg.

"You made me take icky Medicine." Regulus said as he moved out in front of his Papa.

"Yes I did, but I see it made you feel better now didn't it." Severus laughed at the nasty look Reg gave him.

"I guess." Reg answered back making Sirius laugh as well.

A couple hours later found them back at Sirius house sitting on the couch just after Regulus went to bed. Sarah made herself scarce so they could be alone together for awhile to "Work things out" As she said.

"I know it had only been one day Sirius and I have no objections to being your friend but I really want more with us." Severus said as he turned to look at him.

"I know you do and trust me I do to. I just need time Severus." Sirius replied.

"I get that I do, I just hope you don't need to much. I should leave now before I do something I may regret. It was great being with the both of you today. Call me when you want to do this again." Severus smiled as he stood up and made his way out of the house, Sirius doing nothing to stop him this time.

Sirius arrived at work the next day confused more than ever. He couldn't stop dreaming of everything Severus and him could have done together the last couple of years when they were apart. He couldn't help put dream of the other man running his strong hands along his body and bringing him pleasure he hasn't felt since James. He wanted nothing more than to give in and let the other man have his way with him, but he knew he needed to wait, he needed to make sure Severus would be there not only for him but for his son also.

Just as he rounded the corner he saw James and Remus walking his way, he tried to get away before they saw him but it seemed fate had another thing in mind.

"Sirius I have been looking for you. We need to talk." James spat out and Remus looked down to the ground.

"Well I don't have the time, I have a case that needs to be looked at." Sirius replied and tried to walk away only to have James grab him and shove him into the nearest room, Remus following. His heart dropped when he thought about what this could be about.

"Remus told me something interesting that him and Severus have been hiding from me for years. He thought since the person he has grown to love just up and left him for you that it was about time I knew. Do you know what that little secret is Sirius." James spat out and all Sirius thought about was killing Remus. How could he do this. He wasn't even with Severus.

"I don't know what you are talking about. I'm not with anyone so I don't know who you think Severus left you for Remus but it wasn't me." He stated hoping to not get into this conversation. Remus didn't look like he believed him however and just turned away from him.

"Don't play fucking stupid with me Sirius. I know that bastard son of yours is mine." James said this just as he was right is Sirius face. He felt the blood drain from him and tried not to respond to what James just said. "Remus told me while he was all heart broken by Snape. He told me that they kept the secret from me while we were in our last year of school and even up until now. I should have known when you said Snape wasn't the father that it was me. I want my son Sirius." James spat at him.

"Fuck you." Sirius pushed his way passed James and Remus and left the room then the building he wasn't going to have James think he was going to get his hands on his son. He quickly made his way to the Law offices and sat down with the only Lawyer he knew could help him, even though he hated the guy.

"So Sirius, let me get this correct. You got pregnant by Potter in school, he left you to be with Evans. You never tried to tell him he had a kid on the way or a son after he was born. You have been taking care of him by yourself with the help of a Nanny all this time and now James knows." The man stated what he just told him.

"Yes that is correct. I know we hate each other but I was really hoping you could help me. I mean my son is technically related to you." Sirius stated.

"I think we both have grown. You may not talk to your family but Sissy is worried about you. I will help you keep your son away from Potter. I don't see any grounds that he would get him. Your name is just as powerful as his, if not more. Also the one time you said your son met the man he scared the crap out of him. I will write up a affidavit and present it to the Potter's lawyers. When I am dont they will agree to letting you keep him with no interference from them." The man smirked as he sat back in his chair.

"So hopefully no going to court over this. I don't want to drag Regulus into this if I don't have to." Sirius worried.

"Yes I believe they will agree to my terms, as long as you agree to mine as well." The man stated.

"I knew this was to good to be true. What do you want Lucius?" He asked the man across from him.

"Nothing to bad. Just that you come to the house with your son and reunite with Sissy. Your cousin misses you and I'm sure that our son's will get along great, they are also cousins after all." Lucius smiled and Sirius was shocked.

"That's all you want?" Sirius asked a little suspisous of the other man.

"Yes. She has seen you around and misses you dearly." Lucius replied.

"Alright, we will be over tomorrow night. Let me know then how everything went. I will also bring a friend with me if that is all right." Sirius asked knowing he wanted Severus by his side.

"That is fine. I will let her know to expect you guys tomorrow night. She will be so happy. See you later." Lucius said as he got up from his chair and opened the door for Sirius.

"Please just help me keep my son." Sirius was worried the James was going to take the one good thing in his life away from him, he couldn't loose Regulus.

"I will, you don't have anything to worry about." Lucius smiled as they said their goodbyes.
