The demoness slipped into the sleeping mortal's room, her eyes latched onto her prey's chest, listening to their slow heartbeat with a devilish hunger. Silently, she strode over to their bed, her barbed tail swaying slowly behind her as she crawled onto their bed and straddled the unsuspecting victim. Softly, she hummed her deadly tune as her barbed tail pierced cleanly through their chest, as a knife would through warm butter, and wrapped around their still beating heart, but not yet squeezing. "Tell me all your dirty fantasies", she purred before pressing her lips to her sleeping victim to enter their dreams.
