The East Pack's settlement did have running water, but only for crops and for drinking. For bathing they had the river and so Riley could say easily that he had never been in a tub like that. Maybe he'd been washed in a bucket or a laundry basket when he was very, very young, but mostly it was cleaning in rivers. His nose twitched at the scent of strange things in the air, he had a very sensitive sense of smell, and so every new thing that Tao added to the water was another layer for him to experience. At the vampire's command, Riley rolled back on the bed, propping himself up on one elbow, the other hand preoccupied with stroking down and up his already half-hard cock.
