His hips jerked upward involuntarily, and his eyes shot open in utter shock at the electric shock the action sent coursing through his entire body. Suzaku, too, had seemed to freeze at that, and Lelouch couldn't help but repeat the action, pressing their hips firmly together. He groaned low in his throat, and Suzaku's teeth sank into his lips in response, sending identical shudders through each of their bodies.
Then he felt Suzaku's hand snaking between them, unfastening his pants, and was suddenly overtaken by wide-eyed panic.
He opened his mouth to protest, but Suzaku's tongue was on his neck again, and then lower, scraping wet circles around his nipples, and all he could do was suck his breath in sharply as his pants slid down his legs. It's just this feeling, his mind tried frantically to reassure him, It doesn't mean anything. It wasn't as though he loved Suzaku; he just wanted this, and if it helped his plan along some in the process, so much the better. Belatedly, he noticed through the haze of arousal that the tongue was absent from his body, and he pried his eyes open pushing himself up onto his elbows to focus his visible eye on the other boy.
