The teen's breath hitches as she watches the puppy, its tiny body squirming with excitement. She's never felt this way before, this urge, this need. She tentatively brings her hand to her mouth, sucking on her fingers, imagining it's something else, something bigger, warmer. She looks back at the puppy, its tongue lolling out, and leans down, her heart pounding in her chest. She presses her lips to the puppy's muzzle, feeling its wet, rough tongue against hers, tasting its breath. She moans softly, her body aching with a new, unknown desire.
