By the time I finished sweeping foyer which is was very difficult in heels. Almost time for the guests to start arriving. I walked into the main room to see if there was anything that Mistress Nora needed for me to do. When I get to the room I can see Diddo looking very good in her green summer dress, Subserviant in her short mini skirt and Mistress Nora in her black evening dress. Looking down I tell Mistress I am finished tidying the mansion and if there is anything else she needs. Mistress Nora says watching you do the work around the house like that has gotten me kind of aroused and I need some relief before the party starts. With that sitting in her chair Mistress Nora spreads her legs showing me her matching thong. Blushingwith Diddo and subserviant watching I get down on my knees and crawl in between Mistress Nora's legs. I can smell the sweet wetness between Nora's legs. I slide her panties down her long powerful legs. I can see her sex is very nicely shaven. I take my tongue and run it up and down her clit. I can hear mistress Nora start to moan that is when she grabs my head and shoves it in her pussy and holds it there and tells me to fuck her pussy with my tongue. When she does finally climax in my mouth she tells me to finish cleaning her up and to put her panties back on. Once done she tells me to go and watch my face and come back and get ready for the party. With a big grin Subserviant grabs and squeezes my ass as I walk by. I go back to Diddo's room to wash up and reapply my make up hoping I will get it right.
