I'm rather nervous as I wait for Master. My butt plug is in, as instructed, and I'm wearing my regulation lingerie. To my surprise Bri walks in and I learn Master has promoted her over me to be an instructor! She inspects me caressing and checking me all over. I'm made to bend over for her to check my but plug is inserted fully. Then she tells me Master wants to see I've been soundly spanked. He likes to see my cheeks nice and red when he plays with me. Bri gets me in the wheelbarrow position so I'm very exposed for a spanking. Then she uses me as a foot stool to herself conformable. We hear footsteps and panic as Master approaches! Bri is as worried as I am, we both hope Master is pleased with our work!
