Greg leaned down and began to kiss Theo's flat stomach everywhere, using his hands to run up under Theo's shirt at first, as his lips slid across the taunt skin. He thought he could see a roundness to it, and realized that they must have made Theo eat something.
They probably force fed him, he thought grimly and he lay his ear flat on his stomach so that he could look up at Theo's face. He could hear the gurgling of a stomach turning; to Greg it was a good sound, one that meant comfort and satisfaction. It pained Greg that it meant something differently to Theo.
"Leave it in there," Greg said soothingly, his hand moving up to Theo's chest, to find his nipple, and Greg played with it gently, brushing his finger across the sensitive nub, back and forth as he turned his head back to the stomach to lay more kisses across him.
He put his face into Theo's skin and smiled, "You smell good, love. How I've missed you these last hours," he added.
