Amphitrite held on tightly. She didn't need the excuse of falling to press the full length of her body close to his, but the sudden loss of solid ground under her feet made her catch her breath and tuck her head into the crook of his neck.
It was a good fall, a sweet rush, like the sudden crash of familiarity, of home that she felt as soon as she'd seen him. The water was cold and it tugged her down, deeper into old patterns, old loves.
But Poseidon was here - here - and she shuddered in his arms, closed her eyes, and tried to breathe. It was harder than it should have been, and it burned for a moment. She was so much less than what she was. But then something shifted, and the water flowed not only around her, but through her in a strange way that made her more solid, more real than the Amphitrite who walked on land.
And when she opened her eyes, she smiled and placed a gentle hand on his cheek. She caressed him, slowly, as the water around them caressed them, and she could not speak. Her heart was too full for words.
