He'd seen people kiss before, hadn't understood why. It was a weird, difficult way to show affection for someone who spent upwards of twelve hours a day wearing a helmet. It hadn't seemed worth it anyway. Touching someone else in general, really, what was so fascinating about that?

Now he was definitely starting to get it. His eyes fell closed as the kiss changed, leaving him nothing but a wave of blind sensation strong enough to coax a quiet little quavering sound from his throat.

He should be trying to do the same for the Captain, he was sure of that, but he wasn't sure how. All he could think to do was to imitate, trying to match whatever it was the other man was doing with his mouth and hips that made it feel so much better than it should.
