Harry didn't know what had possessed him, well he did of course he did but why malfoy of all people. It had all happened so fast, he'd been out when he'd spotted malfoy and malfoy was drunk, this was perfect. Harry had all but carried malfoy back to his place, in the state the blonde was in it was easy to get him to make the unbreakable vow. He new it was wrong but he needed this, he wanted this more than anything.
When Draco woke up he wasn't sure why but it felt right for him to start making breakfast, he somehow new where the kitchen was. Having made breakfast he took it through the house and opened a door to a room, he new that the breakfast was needed here, he put the breakfast he'd made down on a small table by the door.
The room was kitted out like a nursery, sat on the floor was Harry playing with toy animals, Draco looked round confused. He saw an envelope with his name on it, Draco opened it and read.
Draco
Your probably very confused now, which I guess is understandable. Last night you made the unbreakable vow to for want of a better word become my daddy. I never had a childhood, well not a pleasant one at least. I'd quite like one though. I want a childhood with a parent who actually likes me, who will take care of me and play's games. Someone who will keep me safe. I want a dad.
I will say that I am not heartless, your vow will only last for 4 months, then I will wipe your memory and you will be free to leave.
At the end of the letter was signed your new baby boy. Draco walked over to Harry who was still playing dressed in an adorable onesie, Draco breathed then spoke "come on little one time for breakfast".
The dark haired man, boy which ever, looked up and said cautiously "daddy?", Draco smiled and said "that's right little one".
Draco sat Harry on his lap and fed him, after breakfast he washed dried and dressed his new charge. In spite of the circumstances he found that he was enjoying himself, the blonde had always wanted kids but Voldemort had made it so he couldn't.
Draco new it was punishment from when he didn't kill Dumbledore, Voldemort had seen that what Draco wanted more than anything was to be a father. He realised that he could be a father to Harry, this was perfect.
The first few days when by in a flash of nappies and cuddles. That first night Draco had removed Harry from his crib and put him in the big bed with him.
At first Harry was scared but Draco looked terrified and suddenly broke down saying "please don't make me sleep alone, we can sleep in your crib if you want, we can sleep anywhere you want, just don't make me sleep on my own".
Harry felt concerned and came out of his little persona and asked "Draco what happened?" The blonde looked at Harry and said quietly "I don't wanna wake up screaming anymore".
Harry promised Draco would never sleep alone ever again, he lay down in Draco's arms and the blonde started telling him a bedtime story, about a teddy bear.
Draco was the perfect daddy, in the week Harry went to work for the ministry but when he got home he and Draco would play games.
The blonde had looked up fun activities for kids, and when Harry got home they built a blanket fort. they had slept in the fort that night.
One day he found cardboard boxes and together they turned the stairs into a slide, the blonde loved his new life. He liked making sure Harry was safe and happy, he liked feeding him seeing the absolute trust his little boy had in him, he liked going into the kitchen and seeing the pictures that Harry had drawn him stuck up on the fridge and the walls. He liked being a dad.
The blonde laughed as they made cup cakes, they both had flour and icing sugar in their hair. His favourite sound was Harry laughing. When the cupcakes were cooled and iced, Draco took him and his little Harry to have a shower.
Harry was worried that Draco might get the wrong idea, but he didn't. Draco washed them both then dried and dressed him in brand new footsie pyjamas, this was perfect.
The four months were coming to an end soon, and Draco didn't want to loose the memories, he wanted to be a dad it didn't matter that he didn't have a baby, he had the next best thing, and as long as he had those memories he'd be happy.
When Harry got home from work that day, he found the house empty and saw a letter.
Harry
I'm sorry I've left, I know that your going to wipe my memory tomorrow, and I don't want to loose the best memories I've ever had. Being a dad is the thing I've always wanted, I've wanted to be a dad since I was 10, but to punish me for not killing Dumbledore Voldemort took any chance of me being a father away. I'm not going to let you take those memories from me. For four months I was a daddy. I'm keeping my memories, there mine I'm keeping them.
The dark haired man looked shocked at the letter, he had to find Draco.
He realised with alarm that he had to find Draco before nightfall. He'd promised him he'd never let him sleep on his own ever again.
First he had to see what the blonde had taken with him. He made a list, drawings, Harry's pillow and blanket and one of his onesies.
Harry left his wand on the table and used the floo network to go to malfoy manner. He figured that if Draco was leaving he'd want some of his stuff.
As he stepped out of the fire covered in ash from the fire place, he was almost knocked over by Draco who was rushing round packing. The blonde held up his wand in a vice like grip, his arm was shaking slightly ready to defend himself.
Harry looked at him innocently and said "daddy come home". Harry held his arms out to Draco who dropped his wand and grabbed the man who was stood before him and held him tight "I I can still be your daddy?" Harry smiled and nodded.
Draco looked at Harry trying to stifle a laugh there was a thin covering of ash and soot now covering them both "my little one is all covered in muck, I think we may need to get you into a really big bubble bath with loads of bubbles, what do you think little one?". Harry was bouncing up and down excitedly as his daddy led him upstairs.
