Sirius lay back on the bed, a thin sheen of sweat coating his forehead. His breaths came in short, rapid gasps, each one punctuated by a low groan. The contractions were coming faster now, barely giving him time to rest in between. His hands gripped the sheets tightly, knuckles white as he braced himself for the next wave of pain.

James sat on the edge of the bed, one hand holding Sirius's tightly, the other gently brushing away the damp strands of hair clinging to his forehead. His eyes were filled with worry, but he kept his voice calm and soothing. "You're doing great, Pads," James whispered, pressing a soft kiss to Sirius's temple. "Just a little longer, love. You're so strong."

Sirius managed a weak smile at James, though his face contorted in pain a moment later as another contraction hit. "I swear... when this is over... you owe me... a lifetime of foot massages," Sirius gasped out, trying to keep his sense of humor despite the agony.

"Deal," James replied instantly, his voice filled with love and reassurance. He looked up at Regulus, who stood by the foot of the bed, hands hovering uncertainly, ready to help but not wanting to be in the way. "Reggie, do you have everything? The potions and... whatever else we might need?"

Regulus nodded, his usually cool demeanor cracked with worry. He had already set up a tray with calming draughts, pain relief potions, and a few towels. His wand was in his hand, ready to cast any spell that might be necessary. "I've got everything," Regulus said, trying to sound confident. "I've read every book on childbirth I could find. We're prepared." His eyes softened as he looked at Sirius. "You're doing amazing, Sirius. I'm here, okay? We're both here."

Sirius nodded, too focused on the pain to respond verbally. He squeezed James's hand harder, his other hand reaching out for Regulus, who immediately took it, offering his brother silent support. Another contraction hit, and Sirius let out a cry, his back arching off the bed as the pain wracked his body.

"It's okay, Pads, breathe," James coached, his voice steady. "In through your nose, out through your mouth. Just like we practiced."

Regulus watched, his heart aching as he saw Sirius in pain. He knew this moment was inevitable, but seeing his usually strong and confident brother so vulnerable was almost too much to bear. He squeezed Sirius's hand, offering silent strength, his other hand resting on Sirius's knee.

Sirius's breaths came faster, more labored. His grip on their hands tightened. "I... I think... it's time," Sirius panted, his eyes wide with a mixture of fear and determination.

James's eyes met Regulus's over Sirius's trembling form, and they both nodded. Regulus moved into position at the foot of the bed, ready to help guide the baby. James stayed by Sirius's side, whispering words of encouragement and love.

"Okay, Sirius," Regulus said, his voice steady, though his hands shook slightly. "When the next contraction comes, I need you to push, alright? Just like we talked about."

Sirius nodded, his face pale and glistening with sweat. He felt another contraction building, stronger than the last, and he gritted his teeth, bearing down with all his strength. A pained scream tore from his throat, and he felt the pressure shift as the baby began to move.

"That's it, Sirius! You're doing it!" James said, his voice filled with awe and pride. He kissed Sirius's knuckles, holding his hand tight. "You're incredible."

Regulus's voice was calm and reassuring. "I can see the head. You're almost there, Sirius. One more big push."

Sirius let out a sob, his body trembling with the effort. He squeezed James's hand and pushed again, every muscle in his body straining. The pain was blinding, but he focused on James's voice, on Regulus's steady presence, and the promise of finally holding his baby.

With a final, desperate push, there was a sudden release of pressure, and a new sound filled the room—a thin, wailing cry that was the most beautiful sound Sirius had ever heard. He collapsed back onto the bed, tears streaming down his face as relief and joy washed over him.

Regulus gently lifted the tiny, crying baby, a look of wonder on his face. "It's a boy," he said softly, wrapping the baby in a soft towel before handing him to Sirius. "You did it, Sirius."

Sirius took the baby into his arms, his heart swelling as he looked down at his son's scrunched-up, red face. "He's perfect," Sirius whispered, his voice thick with emotion. He looked up at James, who had tears in his eyes, and then at Regulus, who was smiling softly.

"We did it," James said, leaning down to kiss Sirius's forehead, then the baby's. "You're amazing, Pads. Both of you," he added, glancing at Regulus with gratitude.

Sirius smiled, his exhaustion forgotten as he held his son. "Our little family," he whispered, his heart full. "Together."

Regulus placed a gentle hand on Sirius's shoulder, his eyes filled with love. "Always," he agreed.

The room was filled with a sense of peace and joy as they all gazed down at the newest member of their family, their hearts bound together by love and the promise of the future.
