My slave training continues

I stood there in only my 5 in red stilettos while Mistress walked round me, inspecting me. My budding breasts and erect nipples were quite obvious. I so wanted to be worthy for my Mistress and serve her well. She squeezed my balls "No sub, I own you now, you only get a hard clitty when I desire!" I was then made to put on red stocking, panties and a push up bra. Mistress then put a dog collar around my neck and pushed me to the floor "OK bitch sit" so saying she clipped a dog lead to the collar and made me crawl about the room. Looking uo at her eyes she said" I have a friend coming round tonight. You must please us both or Mistress will be displeased and you know what happens then"
I shivered in anticipation. "We are going to continue your education and journey to the inner core of your being, to be a submissive. Mistress will expose the real you and take you places you can only dream about in your wildest fanatsies She smacked my buttocks several times " you do not want to be a bad dog do you?" The lead was then tied to a knob on a chest and I was told to sit!

Mistress lay on the bed, naked, when a man came in to the bed room. He too was naked and clearly a body builder . She started to suck the mans large erect dick and he clearly very much enjoyed it. For 20 minutes I had to watch them having sex until finally he removed his erect penis from Mistresses cunt and walked over to me. "Clean it slave, suck it" Well I was somewhat surprised but Mistress looked over to me and said Do it" at that I opened my mouth and sucked the dick tasting Mistresses juices and the man's cum. I was just glad to be able to serve and show how submissive I could be for my Mistress. He pulled his dick out of my mouth and walked to my ass pushing it into my back pussy." take it slut, that it,bitch" I was surprised at this as I was owned by Mistress and looked up at Mistress for permission to continue. Mistress just looked at us "OK cumslut please him" and played with her pussy. "You are a plaything to me, you exist only to serve and give others pleasure" The man thrusted deeply into me and started to fuck me hard. He pushed his big dick in and out thrusting hard as my hole widened to accommodate it. It was wonderful as he held my hips bucking me and jerking my lead.
