I remember growing up and finding my older sister Angie wandering the house -- and sometimes the neighborhood -- while sound asleep. The first time I caught her like that I woke her up right then and there. My god I thought she was going psycho on me the way she screamed in terror! Our folks took her to the doctor and were told to be very careful that we NOT wake her up during these episodes. Rather we were to gently guide her back to her bed, or at least just let her wander as long as she couldn't get hurt by her actions.
She left home after high school and I figured that eventually she had outgrown it. Nobody ever mentioned her still doing it. Each of us married soon after leaving the paternal home and ironically found that both couples purchased new homes within six blocks of each other! Shit, we even picked out the EXACT same floor plan! Man did we have a laugh fest over that one!
When I turned 24 and Angie hit 27 our folks hit it big on the progressive slot machine. Make that, hit it HUGE as they both instantly quit work and moved to Florida to 'retire'. Angie and I found we saw each other more often after that just to have some connection with family. One year later my ever loving wife gave birth to a VERY black little girl, which is hard to explain coming from two parents of Scandinavian decent! I filed for divorce two days later after the paternity test proved I was not the father. In our state that was all the cause I needed and she was booted out with nothing but her cloths and her baby.
Living as a bachelor again was a big change as I suddenly realized that she actually had done several things around the house. Just not enough to keep her sorry ass here. Fuck that shit! Angie soon was spending huge amounts of time with me whenever her husband was out of town on business, which was happening more and more as he progressed further up the corporate ladder.
This morning I got a frantic call from sis telling me that she woke up to find eight inches of water in her house due to a broken weld in one of the pipes. I instantly told her they could stay with me while their house was being remodeled. Naturally her husband Rick was 2000 miles away on business and couldn't get back for nearly three weeks.
Two nights later at around midnight I was coming in from taking out the trash when I nearly crashed into my sister as she walked down the hallway. I jumped back startled to see her as she had gone to bed over an hour ago, then noticed the telltale signs on her face that she was sound asleep! Shit was that a surprise.
I followed her into the kitchen where she opened the fridge and got out the milk, then poured a glassful through her empty hand shaped like a 'C'. Milk poured off the counter top, down the cabinet doors onto the floors. Sis put the milk away, chugged from her empty hand and glided down the hallway to my bedroom where she got in bed and covered up as if she was at home. Shit, this wasn't good! Wondering what I should do I returned to the kitchen and cleaned up the mess before getting a blanket and pillow so I could sleep on the couch.

"Dave, wake up," my sister said as she shook my shoulder.
"Huh," I mumbled as my eyes tried to open.
"How come you are out here and how did I get in your bed?"
By then I was fully awake and had swung my legs out to sit up. I looked at her and chuckled before telling her of her late night wanderings. "Oh shit, I haven't done that in over 4 years! Damn it, I hope I didn't make too much of a mess for you to clean up!"
I assured her not to worry about it and eventually she calmed down. Luckily she stayed put the next two nights and both of us thought that maybe it way just a mental reaction to her nightmare of a problem at her house. Then it was Friday night and I woke up around one AM as she slipped into bed right on top of me. I guessed I was sleeping on 'her' side of the bed! It took some doing but finally I was out from under her and then managed to coax her out of bed without waking her. I guided her to the guest bedroom and got her into bed where she started snoring softly right away.
At around 4 o'clock I woke with a start as a moist and warm pussy slipped down onto my rock hard cock. Hell I had been in the middle of a fantastic dream but I never expected it to turn out to be this! "Oh god honey, you feel so good tonight," Angie said softly as she slowly started moving her hips up and down in about two inch movements. "Oh Rick, you feel so good inside of me," she moaned again.
'Fuck' I thought, 'this is just so wrong in so many ways!' My mind was whirling as I tried to come up with a way to get her to stop and then back into her own bed, but how? Her moans were getting louder and her pussy was really working over my cock as she pushed towards her climax. Suddenly I thought, 'Oh shit sis, don't wakeup while you cum!'
I needn't have worried. About ten minutes into her ride she flung her head back and cried out "Oh god Rick, I'm cumming! Oh shit I'm cumming so hard! Yes...yes...yes...YES!!!" Her madly convulsing body slowed to a near stop as she recovered while slowly moving on and off of my granite-like 8 inch pillar. Very gently I tried to move her a bit to start getting her to un-mount me when she started pumping her cunt on me harder and harder...faster and faster.
Oh god this is not good. If she doesn't stop I am going to cum inside of her! A brother doesn't fuck his sister! He doesn't cum inside of her...even if she is sleep-fucking! My hands on her hips tried to slow her down but there was just no way to gently get her to stop!
