A/N: The prompt was the first part and I continued with "Emma took a deep breath..."
Fluffy fluff!
"Darling, what happened?" Killian looked down at Emma, his features paling when he saw the tears brimming up in her eyes against her strong-willed denial of their existence.
Emma took a deep breath and stepped forward, wrapping her shaking arms around his torso. Killian held the back of her head with his hand and wrapped his hooked arm around her, wondering what had upset her like that.
"Emma?" he asked again and she stepped back, reluctantly meeting his gaze.
"I…I…" She took another deep breath, but kept her eyes locked on his. "I don't even know why I'm crying, it's stupid, really. I guess… I guess I just don't have the most pleasant memories with this. I… Killian, I'm pregnant."
Killian opened his mouth to say something, but found that he was choked with emotion, so he closed it again and stared at her, completely taken aback by her revelation. He reached up to cup her cheek with his hand, pleasurable warmth spreading from his fingers over his body, leaving his heart filled with love and happiness. Then he leaned forward and pressed his lips softly against hers, telling her everything she needed to know.
