Dildo riding training with weights on my nipples – to please my Master

On my Master's orders, I am training myself to stretch my pussy and torture my breasts. My Master wants me to be the perfect submissive for the lover he has chosen for me. My task is to fulfil all of my lover's sexual expectations - I hope my Master will be pleased with the progress of his property's training. As usual, my husband knows nothing about this, but he hasn't been involved in my sex life for a long time.
