I panted. I took about half of his length, then moved my hands to his stomach and started riding him; his hands held me by the hips to keep me upright...and in rhythm. My pace quickened as my bottom became a blur of pink, jiggling flesh. I picked up the pace as I was building towards my own climax. After a while riding that magnificent dick, I let out a scream and dug my nails into his thighs. I dropped my weight on him, slipping to my knees. My ass cheeks quivered on his loins as I came hard;. I large sign on the wall displays my instructions. It says "Strip Naked then proceed".I remove my clothes and hang them up. Despite knowing what is coming, my penis is getting hard, very hard. I move the curtain aside. My mistress stands before me. She wears a long black leather skirt, with a long slit up the side, i can clearly see her boots and stocking tops. She wears a white blouse, clearly displaying her black corset underneath. Her long brown hair is in a french pleat. She wears a collar. " What's it about?" She asked me."It's a story about the devil going to hell, and how he came back to earth." I realized that it was a pretty terse commentary on the book, but being that's its a weird book for a teenage boy to be reading I left the description pretty vague.She read one of my highlighted passages aloud her voice competing with the sound of the television. When she was done she look at me strangely, "What does that mean?"I laughed and told her it was a description of hell, and. I asked she where cold? She looked down and smiled, no she said just horny. She slipped on a pair of black spike hills then a transparent black lace knighty. Is that all you are wearing to great that guy I asked her. She said yes, and while looking at herself in the mirror she asked if she looked OK? Her five foot four one hundred pound body is made for sex. I said I think Tim has met his match, there's no way he can go all night long with you looking that beautiful. She thanked me and told me.
