Nineteen years ago Severus had stood outside a home in Godric's Hollow. His grief was silent, tempered by the shock of the Dark Lord's demise. He had stepped into the ruins of the house and saw his childhood friend's son in a crib, a scar bright on his forehead.

He had left the house and fled to Malfoy Manor. To spread the word. To ensure his godson was safe. Two infants whose lives were changing in ways they would never truly understand. It wasn’t often that history veered in such a way.

Severus had spent nineteen years protecting them both as best he could. Even when Harry sneered and stepped blindly into harm's way, Severus had stood in the shadows ready to catch him. When Draco had shrugged his hand and help away, Severus had ensured he walked away in one piece. And after the war he'd kept Draco out of jail and made sure Harry stayed whole.

Nineteen years ago.

Today they had turned the tables.

"You need taking care of, Sev." Draco pushed him onto the bed.

"Let us look after you," Harry said as he began to unbutton dark robes.

They were children, he told himself as he gathered strength to push them away. He was old enough to be a father to either of them.

Then one warm mouth met his lips and another wrapped around his cock and he let his doubts bleed away.

Nineteen years later and it was time for his reward.
