You suddenly feel a hot breath creep over your back in a long exhale that borders on the release of heat from an oven. You slowly turn around to see a titan of an arcanine sitting before you. Her body is taught with muscle barely concealed by her lush fur. Your eyes travel down her body to her slightly spread legs and the rather large vulva pressing into the soft grass and making a steadily growing pool of sexual fluid. This arcanine is in heat.
She sniffs you, her demeanor rather calm and relaxed for her current state. She continues to sniff you. You start to wonder what's going to happen next. She could smell the vulpix's pee and think you are a male or she might see you as a threat to her territpry that needs to be taken care of. Or something else entirely.
