He lapped at it with his tongue before he glanced up, his gaze fixed on Felix's face as he scattered kisses from one side of his boyfriend's chest to the other. With his hands still running over Felix's abs, he bit down on the nipple before moaning somewhat exaggeratedly around it in the hopes of riling Felix up even more.
