She had a sneaking suspicion that the reason it was so good was because it couldn't last. There was absolutely no future for them, no matter what choices they made- and maybe, somehow, God recognized how bitterly unfair that was, and managed to squeeze all the intensity and passion and wonderfulness of the months and years most couples had together into each one of their rushed and frantic trysts.
She wouldn't have actually called what they did together lovemaking- that was a word associated with tenderness, a word for people who were free to meet in their own bedrooms and spend luxurious hours with their lovers, whispering secret things and dreaming of beautiful futures.
But it wasn't just fucking, either- they cared about each other as individuals far too much for that. Fucking was something animals did, rutting in the dirt just to get laid and fulfill a basic biological impetus.
She didn't know what to call it. She suspected that he didn't, either, although they never talked about it during the day. Somehow it was easier to push back the desperation that drove them together during the daylight. Probably it had to do with the other people around them, joking, laughing, and making it easier to forget how painfully alone they really were.
She remembers the first time they were together with painful clarity. It hadn't been something she had expected, that first night when she went to him with a question about some mundane matter long forgotten. He had kissed her first, and she'd been far too startled to react in the beginning.
