Scamp looked down at the squirming, whimpering, clearly eager girl before his eyes flickered up to the trainer holding her in place. He was acutely aware that at the moment her guts were full of sloshing liquid, but his command was quite clear. And the pretty young thing throwing herself at him obviously wanted him to comply.<br/><br/>Rising up slightly, he placed his hands...paws...against Mimi's hip-bones, using the pleasantly curved muscles of her rump to support his weight. His cock slid easily between her waiting folds, the eager pumping of her hips welcoming him as he forced himself into her. Pushing deep into the girl, up to his hilt, he begins to mimic the better trained male dog they were made to watch, roughly and quickly fucking the girl held beneath him. Part of his mind hopes that perhaps the display might attract a more...  permanent ...owner, as the question of what happens when the trainers tire of the pair still worries him.
