Take advantage

I knew it was wrong, knew that I shouldn't do it, but I couldn't stop myself as I looked up at my oldest sister standing naked beside my bed, her long fingers toying with her sex as she promised to do anything I wanted. I mean, really, how was I supposed to resist, how could I have done the right thing with that sort of visual stimuli. I knew I should send her back to her room, to forget this ever happened, but as she asked again, "What do you want me to do, Phil?" I found myself answering her.

"Will you suck me off, Stacy?" I asked, still not believing her claims that she was willing to do anything. My mind was racing, trying to put all these strange occurences together in some logical way. My strange new night vision, the ability to see in almost complete darkness, mixed with Stacy's strange somnambulism. I had never heard of a sleepwalker acting like my oldest sister was, it was more like she was in some sort of trance rather than really sleepwalking, but I didn't know what caused it. Well, I didn't know then, I found out later much to my surprise. "Will you give me a blowjob, Stacy?"

"Gladly, little brother," Stacy replied sleepily, a dreamy eager smile crossing her face as she knelt down beside my bed. "I'll do whatever you want me to, Phil" she assured me, her fingers going to the fly of my boxers, drawing my hard cock gently out of it's fabric prison.

"Oh," I moaned in pleasure as Stacy began to run her hand up and down the length of my shaft, her fingers teasing me as she bends her head over my lap, her lips just grazing the swollen tip of my cock. "That's nice, Stacy," I sigh as she opens her lips, taking me deep into her mouth. I placed my hand on the back of my sleepwalking sister's head as she began to work her mouth up and down the shaft of my cock, sucking intensely on my erection. It doesn't take long for her talented mouth to bring me to the point of climax, my hips bucking up off the bed with each stroke of her mouth. "I'm... I'm going to come," I gasp, my fingers curling into Stacy's long hair as she redoubles her efforts at my words. With a loud moan, I thrust my hips up against Stacy's sucking lips, holding myself there as my cock bucks and jerks in her throat, my thick load shooting down her gullet.

"Thanks, Stacy," I sigh as I release her head, letting her lift her head up, my now deflating cock slipping out of her mouth. "That was great," I compliment her as I lay back on my bed, trying to regain my breath after my powerful climax.

"You're welcome, Phil," my oldest sister murmurs in her sleep, a contented smile on her face as she sits back on her heels in front of me. "Is there anything else you'd like for your birthday present?" She asks me in her strange somnambulist state.
