The thought of Ashton's fingers in his mouth, or over his mouth, stifling his moans, is intensely erotic, and Barcus actually has to pause for a second, shivering at the mental image. "I can...I can control myself enough not to hurt you, idri..."

For a given value of 'hurt', maybe. He's definitely leaving bruises. "Are you afraid to let me get too close to your cock, love? I'm not going to bite you there." That's a near-universal turn off, even for people who like pain.

Lower now, he nips at the outer curve of a pectoral, then licks across the nipple, gentle because that's another place that a hard bite would be unwelcome. "...'course, I'll stop if you tell me to." That goes without saying.
