At first Siya is worried, not knowing how you would react to his cock's behavior, but as your murrs deepen and rumble over his body, Siya fears are at last lain to rest. He knew that his cock wouldn't take in anymore of Arkain's hand unless Arkain wanted it too, so Arkain was in no danger. He settles down and murrs in contentment as Arkain continues licking and swallowing. His own murrs deepen a little as he feels the water around his lower half increase slightly in temperature and begin to swirl softly. Siya slowly spreads his tentacles so that the warm, whirling water moves around them, and his cock continues sucking gently on Arkain's thumb: the long slit on the underside of it opens and the suckers unfold, adhearing lightly to Arkain's arm and providing a sure grip on him.
