During my very first session, Mistress Valkyrie ordered me in slave position in front of Her. I pressed my forehead against the floor, crossed my arms above my head, with the palm of my hands on the floor. She placed Her boots on my hands, while Madame Sarka (who was standing behind me) placed Her boots on the soles of my feet. The pressure was on, one might say. It wasn’t too bad at first, but then Mistress Valkyrie started rubbing Her boots from left to right over my hands. Which was awfully bad for my soft lotion skin. It made my hair stand on end. I promised myself not to make a sound, but my ass started to wobble a bit. So there I was, literally pinned to the floor by two gorgeous Mistresses. They stood on my hands and feet and I stood in awe, needless to say.
