Ken makes a low, hungry sound as Chikusa's nails and fingers encourage him to forget everything else. Nothing's better than Chikusa actively participating, actively doing, actively wanting things. Being one of the things Chikusa wants, and wants badly enough to actually do stuff, is incredibly flattering. Even without consciously reading into the message, Ken feels the importance of it - the satisfaction of it.

As soon as Chikusa's pants are down, Ken's got his cock on his hand, stroking it roughly with calloused fingers. Chikusa reacting to him is the best thing, and he's usually willing to do just about anything to get those reactions. He leans in and nuzzles Chikusa's throat before biting at it again. "Turn around, byon," he orders.
