A/N: Sorry that it's not quite 1,000 words! I must be getting lazy...
Although the sky above is devoid of the brilliant stars he loves so much, there is, of course, one large moon left to light the sky alone. Light leaks through the single window in the room. A moonlit shoulder, hip, her right leg… He longs to touch her.
She lies facing away from him on the sofa, unmoving, save for her soft breathing. It is inaudible at this distance, but he is so familiar with the gentle rise and fall of her chest that he can recognize it from kilos away. He stands in the doorway of the living room, watching her silently. She sleeps with no blanket over her, her nightclothes only slightly out of sorts.
He moves to the sofa, kneeling, smiling widely. She is beautiful even when she is asleep, especially when she is asleep. He loves how her lips look when they are unpainted; they are a brilliant color on their own. Her eyelashes are long even with no mascara on them.
He touches her shoulder softly, burying his face in her neck. Even when she is but a mass of particles in a computer, he can smell her skin: the scent of moss, the color green, what he's always imagined it smells like to simply be alive…
Or perhaps it's just a memory.
But he has her at last, after so long!
He kisses her neck, her cheek, her lips. She pulls away, slightly startled, and her eyes open. She turns halfway towards him. He sits back on his heels patiently, allowing her to view him fully. Seeing his hair, the shine of his eyes in the darkness, his cheekbones illuminated by moonlight, she places her hands on either side of his face and pulls it to hers. She kisses him with a desperate ferocity, and he reciprocates equally.
She rises from the sofa, sitting, pulling him to her as he does the same to her. He sits next to her. They kiss with passion and deep, mutual love in the almost-darkness. He slips his large hands under her nightshirt to hold her bare hips while she grips his forearms, deepening the kiss. His lips move against hers perfectly, countering every move she makes.
After a long while of this (both are thankful for their great lung capacity), they break apart and sit clutching each other tightly, content beyond words in their reunion.
Finally, River lets the tears drip from her eyes. They fall on his tweed until he notices and holds her face, wiping them away with his thumbs. As he gazes into his eyes and she into his, she can see tears in his eyes as well.
"River Song," he whispers, "I've found you at last."
"Doctor," she speaks to him, "you delightful man. How did you even find your way in here?" though she already knows the answer. She grips his wrist without looking away from his face, smiling, fingering the vortex manipulator. "Clever bloke."
He presses a quick kiss to her lips, mumbling, "I've learned from the best, haven't I?"
They sit in each other's company for some time as the sun begins to rise. Light is oozing through the small window. River is properly and entirely drained, and The Doctor's emotions have gone all wibbly-wobbly.
She looks at his face in the growing light: his cheekbones, his eyes, his (lack of) eyebrows, his flopping hair, his chin, his lips… She knows that he can't stay, that he has to leave. Teleport out of the computer and back to reality.
She knows that she must let him. "Take me with you," she whispers. "Charlotte. Miss Evangelista. All of us."
The Doctor answers by looking into her eyes sadly. Then he smiles dismally. What kind of a husband would I be if I left you here?"
She hugs him tightly, pressing the side of her face to his chest, knowing. "One that has a trusting wife, Sweetie."
A tear rolls down his face. He adjusts the vortex manipulator on his wrist, glancing at it over River's unruly blonde hair. He presses a kiss to the top of her head as another tear falls. It lands on River's skin, and she looks up at him.
"Thank you," he whispers before he kisses her one last time and presses the glowing blue button on his manipulator.
He vanishes, and River is left alone in the morning light.
Despite it all, she has faith with all of her hearts and soul that he will return to her.
