Severus didn't want to let go. He wanted to stay here, like this, leaning against the wall, with Remus' cock inside him. He wanted to stay sweaty and messy and with come seeping out his arse and with Remus' arms around him.
For a while, Severus couldn't do anything but breathe, trying to be able to speak. He really hadn't wanted this. He had wanted Lupin to piss off and die, and that determination lasted exactly until Lupin had kissed him again. Merlin, this was awful and wonderful at the same time. Once more, Severus wondered how hate and... something else could go hand in hand this way. It wasn't even because Severus was ambivalent, because if he stopped lying to himself, he wanted Remus Lupin, he wanted him now, tomorrow and next week. Probably for the rest of his life, considering Severus consistency when it came to... when it came to...
He looked up, away from Remus' neck where he had hidden his face. When he looked in Remus' eyes, it was hard not to use that word, or to dismiss the bubbling feeling inside him. Severus gave up. This was just like stopping the sea from flooding the land. He could fight and deny and ignore all he liked, but it would be a lie.
He kissed Remus softly, letting him see that this wasn't said in the heat of the moment, but that Severus, although reluctantly meant the word.
