The position made it harder for Tao to move deeply so he compensated by moving harder, banding an arm around Riley's chest to keep him somewhat still. He bent his head to bite along his shoulder, no fangs, no breaking of the skin, just teeth and tongue flashing out to taste him. The sweat, the anger, feel the blood. All too human. A vampire was less then human, not that they'd admit it, loosing the warmth, the life, many the spirit as well. Shifters were more. More heat, more blood, more power. Again, not that vampires would admit it. They told themselves shifters were animals, beneath them, if anything to stop the craving of that warmth and power and blood.
When Riley spoke it had more of an affect then he wanted. Tao growled, and quickly pulled his head back. His hips jerked and lost their cadence for a moment. "Careful, little wolf, not everyone is strong enough to deny an invitation." He hissed through closed teeth. His jaw ached from trying not to let his fangs descend and plunge into the over heated body in front of him.
