Lucas nestled his head on Claus' shoulder.
"I missed this." he said softly. They were at a hot spring, enjoying a nice long bath.
Claus was holding Lucas' hand under the water and running his mechanical hand through his brother's hair.
"Ouch!"
A few strands of Lucas' hair had gotten caught in the spaces between his finger joints.
"S-Sorry.." he said, trying to remove his hand without pulling the hairs on his brother's head. He couldn't.
Lucas yelped as Claus pulled his robot hand away. He rubbed his head and pouted. Claus chuckled.
"I missed this," he said, echoing his twin's words.
Puzzled, Lucas asked, "Missed what?"
"This," said Claus. "Us."
Lucas blushed. Claus gave him a quick peck on the cheek and nuzzled his chest. Now it was Lucas' turn; he stroked his brother's hair as he held him close. Pretty soon, Claus had nodded off. Lucas hugged him tightly.
"I love you." he whispered.
