There were absolutely no words to describe how Justin felt right now. It wasn't like he had never touched Colin before or been touched by him. There had been a lot of that before Azkaban. Justin had learned so much while being with Colin. This topped all of it, though. Maybe because he thought he wouldn't be allowed to feel this way with Colin again and being able to was just..amazing and indescribable.
His hand worked over Colin, touching him the ways he remembered that Colin liked. He tried to maintain the kissing, but he kept running out of breath and his mouth would have to shift elsewhere while he got his breath back. But as soon as he did, his mouth would be back on Colin's, kissing him as though it was his lifeline. His free hand went to his own, very uncomfortable trousers and unfastened them, too, but didn't manage to push them down because he didn't want to waste any more time not touching Colin's beautiful skin. "I love you," he murmured against Colin, half joyous, half a small cry because as close as he was trying to get to Colin, he didn't think it would be close enough. He wanted so much, yet he didn't know what he wanted at all.
