Disclaimer: Not mine, but I love them like my own. No Peters or Olivias were harmed in this production (in fact, I think they quite enjoyed it).

It happened when she least expected it. Not that she was necessarily expecting it at any time. But certainly not then.

To be honest, she wasn't even thinking about it in the moments before it happened. No, she was definitely preoccupied with other thoughts and feelings like how amazing his mouth felt on her. How he knew exactly how to lick and suck and ohmygodrightthere.

How soft his lips felt as they trailed up her body as she tried to catch her breath.

How the curls at the back of his getting-too-long hair felt so silky between her fingers as she tugged his head back towards her mouth.

How his tongue slid deliciously along hers in the moment before he thrust inside her, his mouth swallowing her gasp as she adjusted to the hot, thick feel of him.

How she held him as close against her as she could so she could hear the words he whispered fervently into her ear—how tight she was, how good she felt, how he loved her loved her loved her.

How she believed in his love for her, especially when he put his forehead against hers and stared into her eyes just seconds before he began to tremble and shake apart in her arms, "Olivia," said so softly she almost didn't hear it.

How she loved holding him and feeling his body wracked with his love and desire for her even as she came apart again herself, moaning his name.

And after, as she held him inside of her for as long as she could, she could think of nothing but the gentleness of his kisses, his nose sliding alongside hers, the sleepy blue of his eyes as he struggled to stay awake.

And then he said it. His lips tilted up into a lazy, happy smile, and then, "Marry me?"

For a long moment, she just stared at him, her own green eyes widening in happy shock. And for just a second—just one-Peter's smile faltered. And then she realized he was waiting for her to answer.

She quickly decided to put him out of his misery and smiled back at him. "Yes." And then it was all kisses and renewed desire, and she was rolling him onto his back and demanding that he pay for catching her so off guard. A demand that he happily gave into several times that night.

Just before dawn as Peter finally fell asleep wrapped around her, Olivia smiled to herself. Peter wasn't the only one who could catch someone by surprise. She couldn't wait to tell him her news—their news. She would wait until he least expected. . .or maybe until breakfast.
