I began fantasizing about fucking her myself, and suddenly I blew my load all over Ryans bedroom door. I swore to myself and hurried to clean it up be...ore they finished. I felt guilty for days after that. I could hardly look Sam or my brother in the eyes. She was his girlfriend, for Christs sake! I shouldnt think about shit like that. And yet, a few days later when I accidentally opened Ryans door after hed told me to wait, my cock hardened instantly when I heard Sam squeal and rush to cover. A couple of hours later, I entered the dining car and saw her sitting alone. I strutted up to her table and sat down without asking. She looked at me with a wry smile on her face, and an invitation in her eyes."I'm Tom," I said."Sue," she replied, with a wink. We both knew what was going to happen. After finishing our meal, I led her to the sleeper car and found my berth. I opened the door and let her enter. She stepped through without hesitation. I followed, closing the door behind me. Once we. I hoped the one in my wallet was OK. Jennifer was staring at me from the bed. “Well,” she said, “you going to join me?” I slipped off my shoes and slid across the bedspread to her. She wrapped her arms around my back and put her lips to mine. Her lips were so soft, and she kissed me eagerly, opening my lips until I felt her tongue slide, wet and warm, into my mouth. I could feel her breasts pushing against my chest, and my hard cock pushing into her belly, and her warm. Actually, the idea of undressing in front of him, have him stare at my naked body and feel our skins touching was just blowing me away, and my thoughts became dirtier and dirtier.Since then, every night I fantasized about having sex with him everywhere in the house: in my bed, in his bed, on the kitchen table, on the stairs, in the backyard while he was taking photos, in the shower after he filmed me… I wanted to suck his cock, lick his balls, taste his cum.I wanted him to lick my pussy, suck.
