It was just after hogworts, you and Sirius been dating since 6th year after being friends for years. You where now married and wanted kids, which can happen sooner than you thought.
"what if I'm an bad mum" you said as you sat in bathroom with Lilly and your best mate (f/n) waiting for your test results. You where worried cos you never knew how to be an mum, yours pretty left and never came back.
"You won't be, you've had plenty of practice with harry and besdies it come naturally" said Lilly.
"you also got us and Sirius who I know will step up to help he always wanted to be an dad" said (f/n).
"I know, I'm just overreacting, but my own mother wasn't around so how can I know how to be one to this kid" you said as you couldn't bear it no longer and look at the test.
"Your over reacting, beside you never needed her cos you've had seen miss potter and me be an mum" said Lily.
"She right" said (f/n) as the test showed the result as you counted to stare at it.
"I am pregant" you said training around to see the happy face of you two best friends who embraced you into an group hug.
"That's great you need to tell him, so come on bring the test" said Lilly as she grab you by the hand and pulled you down the stairs to see remus on the sofa burried into an book, Sirius trying to get harry to say padfoot and James helping best he could.
"Come on prongslet, say padfoot" said Sirius as he seat in front of harry.
"Moon moon" shouted harry as he pointed to remus and smiling, which was adorable.
"Come on prongslet, your killing me say padfoot or even snuffles" said Sirius still trying.
"Moon, moon" said harry smiling and laughing to the point Sirius looked so angry like an child.
"Face it padfoot you can't get him to say it" said remus smirking under his book.
"I so will Mooney, you goddam watch me, now harry say padfoot" said Sirius not wanting to give in to remus.
"Moon, moon" said harry just as before like remus said he wouldn't say padfoot.
"For fuck shake" said Sirius as he crossed him arm like an child in an tantrum.
"Black watch that mouth around my son or I'll wash it with soap" shouted Lilly as she walk over to harry and pick him up.
"Sorry Lilly pleace not my mouth, my wife wouldnt be happy with an soppy kiss" said Sirius looking at Lilly with an pleading face.
"She wouldn't no" you said as you walked up to Sirius and planted a kiss on his lips, which he turned into an fully on snog. You wasn't complaning cos you enjoy this with Sirius.
"Gross get an room" said James as he got up and stood by his wife and son who chewd on Lilly finger.
"Do you two have to be like that" said remus moving his book closer to his face.
"Already have mate plenty of time, also we do it's how I show I love her" said Sirius defending your action with each other as he broke the kiss.
"I think it sweet and you two need to talk so go on" said Lily so eager to see Sirius reaction to the fact he going to be an dad.
"Thank you Lilly, see someone get it and you okay love" said Sirius fully standing up and looking you over to make sure you where okay.
"I'm fine it's just ...." You said as you put the pregnancy test in his hands. This made him look down and stare at it with shock. Was he not happy was he going to leave you.
"This is so amazing, is it ture" said Sirius after minutes of silence before he face truned into an classic grin.
"Yep, your going to be an dad to your own kid" you said with tears in you eyes.
"Your amazing, I'm happy that I have you and now this kid" said Sirius as he picked you up and spun you around before kiss you with joy.
"That great guys, so happy for you" said remus as he got up and hugged you both as soon as he was able to.
"Now guys just to be clear, im going to be second dad" said James joining in on his hug.
"The kid not your love" said Lily rolling her eyes at James behaviour.
"The kid as good as is Lillyflower, his my best mate, so I get to be second dad like he is to harry" said James.
"He's got a point Lilly, but James and remus will you be godfather" asked Sirius as the group hug finally ended.
"Of Crouse" they said together, which made Sirius jump for joy. They are such kids sometimes, but got to love them.
"Lilly, (f/n) will you be godmother" you asked them as you though of no two people better then you two best mates.
"Sure we will" they both said in union as they gave you and Sirius hugs of joy.
This day really couldn't have gone any better now that you had this amazing news and you had an family right here to help you. What more better is that you had an amazing husband know an Sirius black to be the kid dad and help you out. You where going to be an family and nothing would changed that. This day you'd remember for life.
