Had it been under other circumstances, had Loras not given himself to Renly, had he not loved another man on another leven than he loved the man beside him, Loras might have given in to the urge to find the Jedi's lips with his own and kiss him, to see if Obi would kiss him back. As it was, Loras was stunned, if not a bit startled by the action. Obi never even touched him, not unless he was punching him.
"Obi?" Loras asked, his voice too small for who he was. He opened his mouth. Shut it. Opened it again. He wanted desperately to tell Obi everything, that he liked men and to please not tell anyone else; but he couldn't. He only let his eyes fall shut, a dull ache collecting in his gut as he touched a tentative hand to Obi-Wan's strong forearm.
Then the arms were gone. The weight of Obi's chin was gone. Loras collected himself in a surprisingly quick manner. "I better be first," he replied, managing to keep his voice from cracking.
