When Dad was alive he took real good care of Mom. For as long as I can remember Mom has been a sleep walker. Dad had a thin line tied between his leg and Mom's ankle and when ever she started sleep walking he would guide her back to bed. She did not always sleep walk but when ever she felt stressed she would. Like the time her brother Walter was injured in a car accident. Mom woke up three times that night and Dad had to get her back into bed.
The first time I noticed it was about a week after the funeral. I had not been able to sleep myself and was in the kitchen when Mom came in all wide eyed and totally unaware of where she was. I watched her move around the kitchen for a moment or two and knew she was sleep walking. I gentle took her by the arm and guided her back up stairs and into her bed. She did not resist or try to pull away. The moment her head hit the pillow she was back asleep and I left her there.
I was going to leave town and take a job over at Mountainview but when Dad died so quickly I decided to stay home for a while. Now I don't know what to do. I did call the next day for a doctor appointment hoping I could learn more about sleep walking and what to do if it happens again.
A few days later Mom and I talked at breakfast about her coming to live with me in Mountainview as part of the job offered to me there was a fully furnished apartment. It had two bedrooms and I thought that would work out fine. I was wrong.
That night Mom woke me as she opened my bedroom door, came in walked around and left. I followed her down to the basement where she turned on the washing machine without loading it.
Then she went back up to her bedroom. I watched hoping she would not hurt her self and if it looked like she might I would guide her back to bed.
Standing in the center of the room she pulled her night gown off over her head and stood there naked. I had never seen my mother naked before and I was surprised at just how lovely she was. I am twenty two and Mom had just turned forth one. Mom likes to exercise and workout on her tread mill.
She is five foot six, very trim with real muscles on her legs and arms. Her stomach is flat and her fine tight little ass it as firm as any I have ever seen. Her bush does not match her blonde head. I was still observing just how lovely she truly was when she sat on the bed.
I thought she was going back to sleep but instead she lifted her legs spreading them wide. She placed a hand between her legs and started to rub her clitoris. My Mom was masturbating and that some how turned me on.
Watching my Mom rub her clitoris and with the other hand she squeezed and pulled hard on her nipples all the while rolling her head from side to side. I got up close to the bed and pulled my cock out and started to masturbate along with her.
Mom moaned and lifted her ass up off the bed. Thrashing around I thought she would wake herself up. I was going to move back but instead I shot a load of thick milky sperm out across her face and breasts. I could not stop as spurt after spurt shot out coating her body with the milky stuff.
She stopped moaning and blinked. I moved back toward the door. I was at the open door when Mom sat up and looked straight at me. I was so ashamed and embarrassed I quickly turned dashing out the door and back to my room.
I lay awake for a long time waiting for her to come into my room but she never did. I fell asleep and woke when I heard her call up from the kitchen that breakfast was ready.
Mom was all smiles as she is most days. Nothing was said about last night so I figured she must have been sleep walking after all. Of course I did wonder how she felt when she found dried cum all over her body.
My old car needed some minor repair so I decided to do that this morning. I put my car up on jacks and pulled the wheels. I got out my tools and when I started I found I was missing a special wrench I needed. So I went back to the garage where Dad kept his tools and found his big tool chest locked.
I went in the house to ask Mom if she knew where the key was kept and found her sitting on her bed with several Polaroid pictures spread out in front of her. She was sobbing and holding a tissue to her nose.
I leaned in the open door and said "are you alright?"
"Mom looked up at me and said "Yes, I am just looking at some old photos of Dad and I on vacations back a few years."
I took a step into the room and said "Can I see?"
Mom scooped them up and straightening up said "No: these are private pictures."
I noticed one photo slipped off he end of the bed and fluttered to the floor. I stopped in my tracks and hunched my shoulders more of less saying "well okay."
I did say out loud "Do you know where the key is too Dad's tool box. I need a wrench."
Mom got up and going to Dad's chest of drawers she opened the top drawer and handed me a key.
I took if with out further words. Mom turned back to close the drawer and I quickly bent down picking up the Polaroid and went out the door.
I was all the way down to the kitchen before I looked at he picture. I was a picture of Mom on her knees naked between Dad. He was in back and from the angle of the picture I could only assume he had his cock in her pussy from the rear. This in it's self would not have been a big deal but there was another guy in front of Mom with a very sizable cock in her mouth. I stopped in my tracts and looked at the picture for a long time. My Mom and Dad were swingers. "Well I'll be a fucking monkey's uncle."
I bet the other ten of fifteen pictures Mom had laid out were all the same. Then I wondered if they were all of the same vacation or were there more and different vacations as she called them. I knew that Mom and Dad had gone on several vacations by themselves after I was old enough to stay by myself.
Boy this was something to fine out your parents are swingers. Especially after just seeing your Mom naked for the first time the night before. It gave me food for thought. Then I got an idea. It was not an up standing and highly moral idea but more like a dirty filthy lustful idea.
I opened Dads' tool chest and got the wrench that I needed. I was squatting down by the front wheel thinking and not doing much work. I was looking at the brakes but the vision I was seeing was of my Mom with a strangers cock in her mouth.
