Joshua's ear flicked back. Purring? He wasn't hearing things was he? He left off his exploration on his master body, drawing away slightly. His eyes narrowed slightly and he took a sniff. He didn't smell like a cat. His mind was quickly distracted by the sensation of his master's fingers inside him. He shuddered his ears flat against his head. With a low growl his hand went back to stroking his master, spreading the lube up and down the stiff rod. For a moment he thought of what he must look like. A wanton. Practically a slut. His lip rose in a silent snarl. Maybe mating season was coming early this year. He shoved the embarrassing image from his mind, focusing more on the sweet skin of his master's chest and neck. He moved again to tease his master's ear lobe, biting and sucking in turn, trying to make his master moan. His hand kept up a slow teasing pace, slowly picking up speed, alternately teasing the head and fondling his balls. He licked his master's neck again and took a quick bite at the base before sucking it, then another nip, making sure to leave a plain mark there. He rose a bit and half smiled. "You can collar me, but I can mark you as well." He murmured to himself.
