Daisy tried her hardest to contain herself, biting down softly on her lower lip as Reiko's tongue probed her nether lips, forcing moos of pleasure from the beefy morsle.  The girl coughed slightly as her head was sucked into the stomach cavity, hot gases steaming across her face.  The insides were coated with thick tummy slime that oozed from the walls, smearing across Daisy's face as she was slowly pulled inward.  Her legs were trembling outside the puppy's mouth, her toes curling as she drew closer and closer to orgasm.
