The first change in our relationship since our father left happened on Christmas morning. As usual, I woke before my sister, and started the coffee, hash browns, and eggs. We had agreed that neither of us felt up to celebrating the holidays, so when my sister rounded the corner into the kitchen, my jaw dropped. She was wearing a simple pair of boy shorts, and nothing else. I was silent, as she grabbed a coffee mug, both from shock, and being unsure what to say. As Ailiyah turned her back to me, I saw the back of her panties had slid into the crack of her perfect ass, and struggled not to stare. Ailiyah sipped her coffee, then let out a content sigh, before turning toward me. Without a sound, she dropped to her knees, and gently slid my shorts to the floor, freeing my semi-stiff cock. Looking up at me with a wicked grin, she leaned forward, and slowly slid her lips around me, slowly pulling me further into her mouth with each bob of her head. Her hand slid down between her legs, and Ailiyah started rubbing her pussy through her silky panties, letting out a long, satisfied moan. I leaned backwards, putting my hands on the counter behind me, as I was unsure if she wanted to be touched.
In a single motion, Ailiyah slid her free hand up, and stroked her fingernails gently up my scrotum, as she swallowed me whole, pulling my cock into her throat. She looked up at me, and started swallowing forcefully, which made it feel as if her tongue were wrapping around my shaft. I struggled to control myself, but eventually let out a loud moan, letting my sister know that I was about to explode. Ailiyah smiled, as she gave me one last long stroke with her lips, swallowed again, and squeezed my balls gently, knowing that this would send me over the edge. As my hips bucked, my sister pulled my throbbing cock from her mouth, looked up at me with a loving gaze, and stroked me, as I came all over her perfect face. As I stared down at her, she seemed to be in a state of bliss, as I painted her face. As I finished cumming, my knees buckled slightly, and Ailiyah giggled. She stood in front of me, and kissed me deeply, pressing her body against me, as her tongue slid into my mouth.
"Merry Christmas, dear brother. I'll be back for breakfast after I shower. I love you." she purred,
When she returned to the kitchen, she acted as if nothing had happened. Ailiyah was dressed in a pair of festive pajamas,and acted as if nothing had happened. Of course, even though we had taken an extended break from sexual contact, this behavior fit with her attitude from earlier. She simply seemed to initiate intimacy without a second thought, any time she wanted. It seemed in her mind that she had simply given her brother his christmas gift, no better than a gift certificate. I looked at her as if I were asking a question, but she refused to take the bait.
After breakfast, I resigned myself to getting no answers, and started cleaning the dishes, as m sister retired to the front room to read. I had finished the dishes, and was putting them away, when I heard her voice in a tone that sent chills down my spine. That single word screamed that something was wrong.
"Brandon"
