Isaac sucked lightly on Cormac’s nipple, teasing it with his tongue as he did. He rolled Cormac’s other nipple between two fingers, not pinching too hard. He did, after a few licks, give just the gentlest bite, making Cormac gasp.
Then Isaac switched nipples, playing with the wet one and putting his mouth over the other one, immediately earning a whimper from Cormac. Isaac sucked harder this time, and Cormac made a loud sound. “Okay, okay,” he said, panting. “Okay, stop, I get it, I believe you.”
Isaac stopped, getting up. He was straddling Cormac, who was flushed in the face and looking up at Isaac, his hair a mess even though Isaac hadn’t touched his head. “So anyway,” said Isaac. “The reason why we have nipples even when we don’t need them is because touching them feels good.”
