Making my slave clean my feet and swallow through her nose part 2/2

We were starting training and surprisingly she was very obedient, perhaps because of her eighteen years at the time. I start by making her clean my feet with my tongue and then I put it hard on her throat until I cum and make her swallow cum through her nose. Finally, in part 2, I take her like a dog on a leash to the bathroom and make her a human bathroom.
