Much of that came from being avid readers, and we had long enjoyable conversations about books we had both read. I still teased her occasionally about...her covert love of romance novels, which after a few blushing episodes she learned to take with good grace.And the sex was ... spectacular. Her body was magnificent, inside and out. She had the tightest pussy I'd ever felt, and she was even more beautiful when nude. And she was completely at ease when showing me her body, in contrast with her. I couldn't afford to have the cars behind me to honk their horns and cause a scene. I went about halfway down the block, pulled into a parking space, and had to catch my breath. I hadn't taken a breath since I saw my Dorothy and her paramour in the motel lot. Once I could breathe normally again I called in to work and said that I had something that didn't agree with me for lunch, and I needed the afternoon off.Then I did some checking at the motel, and found out they meet there every Tuesday. “Don”t worry, we will!” Sis chuckled as she grabbed me by the hair and led me into the den and sat me down on the sofa! She sat on my lap and gave me a good hard slap on the face! “That”s for getting me all hot & bothered at dinner tonight in front of Mom you bad slave!” “But you started it” I protested!! Sis gave me stinging blow!! Then another even harder! “Don”t you contradict me!” “I”m your Mistress Sister! You”re my slave and will do what I say!”Sis got up and stood before me and pointed. ‘Give to me . . . do not ignore me tonight’ An outrageous idea to put upon me! ‘I don’t care anymore – do anything, as you please.’ ‘You want me to don’t you?’ ‘Then find a way and now!’ ‘Do it – JUST do it.’ ‘Oh . . .Rachel.’ With that we fell upon each other, intentionally fierce, rousing in war like clamour, no ambiguity to her pleading THIS time, her openness in wanton exploration of every conceivable idea, a posture constructed for one purpose only, her complete fulfilment. She mouthed to.
