Longed-For, by Gordon Lawrie

She gazed up at him. "It's been a while, hasn't it?"
 
He returned her smile. "Too long." He realised how much they needed this.
 
He asked, "Are you sure you're ready?"
 
"Don't be silly. Hurry up, it's cold."
 
Gently, he slipped inside. She gasped.
 
"Goodness, you're freezing!" she said.
 
"What do you expect?" he said. "We forgot to pack pyjamas."
 
"We haven't been camping for years. We were always going to forget something." She zipped up the bag. "Come, hold me tight, keep me warm."
 
So he did. And within a minute or so, both were in deep, longed-for sleep.
