Foreheads touching, Owen and Cristina pant in unison, coming down from ecstatic highs. Their mouths seek each other out for tender kisses, before he moves off of her. He gently guides her onto her side before grabbing a brush off of her nightstand.
Cristina sighs happily as he begins to brush her hair. He has always loved her hair, long and lustrous and dark. The streak of white hair only adds to her beauty. He pulls the brush through her thick hair, which curls around his hands. Once he's satisfied with his work, he puts the brush back on the nightstand and turns off the light.
Owen lies back in the bed, spooning Cristina. She shifts closer to him, as he runs his hand down her bare arm. She still takes his breath away, after all their years together. They've worked together and left their marks in the field of medicine. They have children and grandchildren, and many memories filled with love and laughter. Their hair may be growing white, and lines may mark their faces, but the magic between them is eternal.
"What are you thinking of?" Cristina asks.
Owen smiles, continuing to stroke her arm. "Thank you for the first forty years. I can't wait to see what's next."
