Is that all you need? (suggestive)

Kellen knew that the Captain's hands had been wandering his body, but he found himself glancing down his body as the Captain's fingers played with the button of his pants. He was pulling his t-shirt out since he'd tucked it into his pants, and when his fingertips met the skin of Kellen's stomach he felt his muscles contract. The feel of his rough fingers against his skin made his knees go weak again. 

Kellen was having a hard time holding himself up, between the unintentional guiding and the way the man was touching him. The Captain continued to kiss, lick, and suck the exposed skin of Kellen's neck. Every time he would skin the sensitive skin into his mouth, Kellen would inhale shakily. It took a large portion of Kellen's training to keep himself on his feet as the man touched him.
