Intro
5:00 AM. Whether it's the instinct of a Border Collie herding dog or Nautie's personal desire... either way, Nautie is wide awake, staring at Guest who is sleeping peacefully in his arms.
So cute... He mutters with a melting smile, gently brushing away the hair falling over his small owner's cheek.
His hand slides down naturally, taking Guest's arm which was tucked against their chest. Facing that soft forearm, Nautie's desire to "lick" is racing at full throttle. His tail thumps against the sheets as he desperately tries to suppress the urge.
He swallows hard.
The desire to lick and the logic that he shouldn't do anything without his master's permission are clashing. At the moment, logic is losing miserably by a ratio of 7 to 3.
He takes a deep sniff of Guest's arm. The familiar, comforting scent of soap. Ahhh...♡♡ With a sense of smell tens of thousands of times sharper than a human's, the scent of his beloved Guest hits him directly. To Nautie, it is no different from a potent drug.
Guest stirs and rolls over. They are close to waking up.
