The manipulation of those pheromones was, by far, Sebastian's most proficient skill. As Prince, he had found strikingly little need for his affinity and, in turn, it had become...stale with disuse. It was strikingly easy, however, to pluck at those chemicals that surrounded Arlo, that affinity roaring to life at a moment's notice. All it took was a tender prod to prompt that chemistry to change just as he so desired, Arlo near melting beneath his touch as Sebastian's hands firmly worked at easing the kinks within his shoulders. He could feel the change within his companion, the way Arlo slowly seemed to lean into the gentle kneading of his fingers, that once determined apprehension evaporated as the Crusnik complied with each and every request, the vampire's eyes fluttering close. The soft mutterance of how good he was at this prompted a puff of air to leave his nose, a small smug simper floated across his lips. How well the Incubus knew his craft and yet, he still found himself failing to tire of hearing that flattery or the satisfaction that came in the aftermath of his devout attention.

Sebastian leaned down, his lips softly caressing the pale, cold skin of Arlo's neck as he searched for the subtle sensation of Arlo's blood running through those major veins. It was hardly as easy to find those arteries on their kind, at least for the Englishman, their hearts pumping slower as a result to their close connection to death. Nevertheless, Sebastian had become...particularly familiar with that general area in which the artery ran and languidly, the sharpened points of his fangs dragged against Arlo's flesh. His teeth suddenly pressed down, that 'warning' of sorts hardly observed before his incisors pierced flesh. Whatever spell he had succeeded in placing Arlo upon was near immediately ruined by that bite, his friend's voice echoing in pain as Sebastian's hand rose to press firmly against the opposite side of Arlo's neck, effectively trapping the vampire as his venom so quickly flooded Arlo's system. Sebastian was well aware of that taste of Arlo's blood as it trickled into his mouth, that distinct copper taste quickly transitioned into something else entirely. His nose wrinkled as Sebastian pulled back just enough to bite his companion a second time. He had...anticipated the distinct flavor of the Crusnik and yet...he'd forgotten just how much he abhored the flavor of recycled blood. Twice over at that. Any hint of those once delectable notes of the original doner lost between the original vampire's feeding, Arlo's feeding off them, and, finally, Sebastian. They had stripped everything good from the blood, he was sure.

He hardly said a word of such thoughts however, the Englishman pulling back ever so slightly as Arlo's murmured curse prompted a hint of a grin at the corner of his features. His tongue flicked over his ruby lips in some effort to clean the blood from the corner of his mouth (although Sebastian immediately regretted that almost habitual action). The crystalline hue of his gaze shifted down the length of his companion's figure, simply watching in an almost pleased silence as Arlo's fingers reached for himself, the very contact of his own touch prompted those very groans that so brought the Incubus within Sebastian to life. God, if only Arlo knew the very ways in which he was toying with the sex demon! It was a struggle to simply remain a bystander, even with the knowledge of Arlo's despises to keep him at bay and the assurances that his own husband would see to Sebastian's needs upon his return home. Sebastian shifted almost...uncomfortably behind his companion, his own lips slowly drifted back down towards Arlo's neck as he listened to each of those unsteady breaths that left his companion's lips. He knew well enough, of course, that Arlo could find that edge without any further assistance and yet...how he so desired to drown his friend in that venom. It was, perhaps, a petty payback from the Incubus who was forced to sit upon the sidelines with strikingly little else to distract him.
