Stepbrother Dirty

by Tess Harper

  I flushed because he was right. I had masturbated more than once with his face in my mind over the years. A favorite fantasy had me spread out on one of the big project tables while he pounded into my pussy. I just hoped I could satisfy him with a blowjob. It was still cheating on Harry, but it didn’t feel quite as wrong as going all the way.

  “Touch yourself.”

  “What?” I asked, slamming my legs shut, slightly horrified at the thought of him watching me with those intense eyes.

  “You heard me. I want to watch you do everything you do to yourself at night.” He smiled before adding, “Do it or no deal.”

  Trembling, I reopened my legs and lowered my right hand between them, cupping my mound. My left hand went to my breast and slowly rubbed my nipples, lighting little sparks of pleasure across my nerves.

  I traced the outline of my pussy through the damp white cotton covering it. I slide my finger along the slit before sliding upwards to push inside my panties. I let my eyes slide partially shut, enough so that the room was less focused and I could imagine I was safe at home. Nothing strange was going on. I was just laying in my bed releasing some tension after a long day.

  I was soaking wet and there was no denying that I was aroused by this whole situation. I started rubbing my clit in small circles. I couldn’t hold back the low moans. “James,” I gasped. “Do you want me to take them off?”

  “Yes,” he answered, his voice clipped. I reopened my eyes to see his pants were undone and his cock was in his hands. That sight combined with my fantasies was too much and I climaxed, biting back a shriek as wave after wave of pleasure crashed over me.

  “I didn’t say you could come.” His voice was cold.

  “I’m sorry, James,” I answered as soon as I found my voice again. “I am a slut. I saw your cock and it turned me on so much that I came before I could stop myself.”

  “You’ll have to be punished then.” His voice sounded almost gleeful. “Get on your knees and open your mouth.”

  “So,” he began, “you like to be watched.”

  That was not what I was expecting.

  I looked up to see him leaning against his desk, blue eyes twinkling with an amusement that drained the coiled tension out of me.

  My lips curled into a smile. “I do. I don’t think I’m the only one.”

  He laughed. “You most definitely are not. I always knew the two of us had a lot in common. I never realized just how much it was.”

  “Did you know it was me from the beginning, Aaron?” I asked, relaxing back into the soft leather chair, allowing my legs to fall apart ever so slightly.

  He shook his head. “Not right away. I didn’t even realize it was the same office at first until I counted windows.”

  “What were you doing over there?”

  “Evan Williams,” he answered. “One of the other partners has a place in that high rise and he asked me to water his plants while he was out of town. Usually he’d make one of the secretaries do it, but I told him to stop treating the girls like personal servants, so he made me do it.” He laughed quietly before turning serious. “When I realized it was you, I almost stopped but. . . you were just so fucking sexy. It’s sick. . . to want your own stepsister, but I enjoyed watching you. And I’d do it again.”

  “You’re not the only sick one,” I countered. “When I realized it was you, I was afraid of how you’d react but I wasn’t disgusted. I’ve been thinking about you like that for years.” My voice dropped and I stared at the floor. “Every time I touch myself at night, I’m wishing my fingers were yours.”

  I looked up to see my stepbrother staring at me with a look of pure lust on his face. And I took the time to really look around his office and see it as something other than “My brother’s office.” It was on the corner of the building and two entire walls were made of glass. At night it would be like being inside a fishbowl.

  Suddenly I was very very wet.

  “You noticed the walls huh?” Aaron asked, standing up and walking to the wall behind his desk. “The view is amazing, and it feels so free and open. I’m not going to lie, the first time I walked into this room I thought about how amazing it would be to fuck someone against that glass wall.”

  I whimpered softly at the image that flowed from my mind to that spot right between my thighs.

  “When I saw you watching that couple fucking across the street, I thought I was right about you. You weren’t embarrassed at being caught watching real life porn by your stepbrother.” He turned back to me. “And you weren’t just watching them because they were having sex. You were watching them because they were being public about it and they knew it.”

  “It’s getting a bit dark in here, Aaron,” I said softly. “Would you like me to turn on the light?”
