"Good boy" she said with a satisfied smile on her face. "Here help get me out of this corset I can't breathe in this thing." As I undid each clasp I n...tice just how tight it was and I wondered how did she get this thing on by herself without anyone helping her? She peeled her black satin panties off and tossed them towards the closet door which was closed. She was now clad in only a black garter belt and sheer black stockings. She turned around slowly to face me and my eyes were immediately. For that's how she regarded Guy now.He was hers.And Guy was content with that.He had long yearned for sex with "Margo" and now he was getting it!That it was on her terms and conditions seemed a small price to pay.Her condition now was for him to wear the cruel adjustable cock-ring when he was performing his duties. She said it was good etiquette if the boy was to learn correct behaviour when fucking.Even if he was simply performing cunni on her before she went off to work some mornings.But in. The desk rocked. Rosie let out a strangled noise. Taking him slowly, inch by inch, had been bad enough - but this was different. This was brutal.He started fucking her, thrusting in and out of her with such force and speed that her upper body was bouncing up and down on the desk, her tits sliding over the mess of papers he had made there. "You do what daddy tells you, slut" he was saying, "You stupid fucking cunt." Her arms were flailing desperately, trying to grab onto the desk like she. But whenever she looked at me i felt she had magnet in her eyes at that age too, no wonder she pulled dad towards her, later i came to know that this was her second marriage too..Dad had to go outstation for few days this he told me before leaving and asked me to take care of the house and not to fight with his wife, i did not even reply to him, but thought to myself that i should come home early in his absense, that night i was having my food which was in the dinning table, she came to serve.
