Y......Yes Mistress" I stammer backNever in a million years would I have considered a feminine name formyself....still I felt it ...as right and I blushed at this thought."So slave Ruby, time to deal with that hard TINY dicklette ofyours....did you bring the frozen peas," she quipped."Yes Mistress." My blush deepening at the emphasis of tiny as I pickedup the peas.I had wondered rather naively what they were for, now it dawned on me."Okay stay standing so I can see and place.
