The answer...

"Chris, what are you doing?" Sky's voice came out in a half-hearted protest. 

Chris's lips brushed against Sky's neck, his breath, a warm whisper, caused a ripple of sensations to course through Sky, as evident in the goosebumps Chris felt on him. Finally. That was at least something. 

 "Merely appreciating your unique aroma." He said before raising his head again to look at him, asking, "Are you this guarded because you think I'm going to unlock the height of seduction no one has gotten to?" Chris teased. 

"Arousal can be contagious. I don't want you transferring some to me. So you'd better return to your senses soon." Sky lectured in a heavy tone.

"But it won't be bad if you were," Chris whispered to him before he leaned in closer, his breath ghosting over Sky's neck, making him stiffen beneath him again. Slowly, Chris inhaled, taking in Sky's scent. He whispered against Sky's neck, his voice a low murmur, "I like it."
