It was time to serve Mistress and Master their late breakfast. They had been up a while and from the sounds clearly enjoying themselves. I had been busy with the chores I had been set: polishing boots and tidying the playroom after the previous night's play session. I took the jam covered toast and cups of tea to their bedroom. I walked in, placed the tray on their bed and knelt down, my head lowered. Mistress walked over and inspected me. She liked to check that I had not fiddled with anything she had placed on me. My cock was secure in its cy cage and she rubbed it with her foot. She enjoyed making it stir then seeing my discomfort while it remained constrained. She squeezed my nipples hard like she always did; she loved to hear me moan but the gag she had placed on me kept me securely muffled. The fact that she had placed her worn panties in my mouth first behind the gag ensured a snug fit! Mistress removed the gag and told me to hold the plate out with the toast on. As I did so, Master came over and stood with his now erect cock pointing towards me and over the plate. He started playing with himself as Mistress nuzzled his neck and nibbled his ear. They had clearly been planning this carefully as he soon came, directing copious amounts of cum carefully all over the jam covered toast. The contrast between the dark colour of the jam and creamy cum added to the humiliation that I realised I was about to endure. Master sat down on the bed and Mistress, standing beside me, took the plate off me and pushed me forward towards Master's still erect cock. She pushed my head onto it and told me to clean it thoroughly. i did so. Mistress then told me to start eating the toast and handed me the plate. I had to eat every last piece as they both watched and commented how submissive I was and how much they enjoyed seeing me humiliated. When I was about halfway through, Mistress told me to stop and knelt down beside me. She whispered how much she loved to humiliate me in different ways. She then moved her head over the remaining piece of toast and carefully spat several times all over it. She picked it up and, telling me to keep chewing, fed me the rest of the toast and jam now covered with cum and spit. She looked at me as I chewed and smiled that wicked grin that showed how much she was enjoying herself. When I was finished, I remained kneeling. Mistress reached for a tall glass beside the bed and, opening her legs, she peed into it filling it to the brim. She was well practiced in this art! I could see that it was not her first pee of the day as the colour was a light golden yellow, but she had clearly been storing it up. I knew what came next. She carefully handed me the now warm glass and I took it with both hands, placing it to my lips so I could smell her aroma. I waited for Mistress' command then when ordered drunk every drop down without stopping. As I did so, she knelt down again and looked directly into my eyes; this was one of the occasions when I had to look back at her and not keep my eyes down. She loved to see the look in my eyes as I submitted in this way. Handing the glass back to Mistress, I could feel my stomach full of her piss and my mouth tasted strongly of it too. The sense of humility was overwhelming as I contemplated that I was now full of the pee, cum and spit of my Mistress and Master. Another day had begun in their service....
