Kibbles and Switch
The act of secretly having a dog do the lap work during an oral pleasure season and taking the credit for a job well done after climax is reached.
Johnny was going down on Sussie and a sudden tounge cramp made him unable to preform. Rover was watching as usual. Johnny quitly motioned Rover under the covers were Rover proceeded to vergously lap Sussie into frothy ecstasy. Upon Sussies boisterous explosion Johnny shewed Rover away. With Sussie being none the wiser Johnny took credit for Rover's lingual prowess. Thus pulling the old Kibbles and Switch.
