What is normal? Maybe whatever you are accustomed to or maybe just whatever you have learned to tolerate. My family of three was a little of each.
Dad is a coast to coast trucker who makes a lot of money. He paid off the house years early and I always had whatever I wanted, from cars to college. His line-haul (settlement) checks were direct deposited to a joint account that he had with Mom and later with me as Mom became more of a vegetable.
I don't think Mom had any health issues; physical at least. She drank, watched television, and occasionally went out during the day. At night, she took sleeping pills. I don't think they were legal because every time the old prescription bottle would get almost empty, it would fill up again.
Dad never did anything with Mom except to fuck her. He would come in during the night and I would hear their bed, then he would leave or spend a little time with me if I was home and awake. In the morning, Mom would ask me if Dad had been home. I guess he fucked her in her sleep and did not clean her up after.
His coast to coast trips would not always bring him near the house, so sometimes he would not get home for weeks.
As I got older, Dad began to tell me things. He said it was lonely out on the road with no pussy. There were plenty of "lot-lizards," (hookers) in the truck stops but he did not like wearing a condom and he would not touch one without protection. That and the fact that he liked to run hard and make the money, not hang around truck stops like a lot of drivers. He told me when he paid off his truck, both the tractor and the trailer. Then he paid off the house.
I said, "Dad, you should take a vacation."
"Maybe a vacation would be nice if I had a girlfriend, but your Mom is not girlfriend material. So I may as well just keep running hard." That was the first time I ever heard him say anything against her.
That leaves me: I guess I am not like every other 20 year old either. I had poor marks in high school and did not think I could qualify for college, but I managed to get into a general business class. My dream was to be an architect but no college would take me. Worse yet "NV" was the only letters that belonged after my name: (Near Virgin.)
There had been a party where a lady got roaring drunk and fucked every guy there. I wondered for a long time if we had raped her because of her drunken condition but she had been the aggressor and really seemed to be enjoying herself. And there was the older woman who had asked me to come up to her apartment and help her with something. I helped her three times that night but when I looked at her in the morning, my only goal was to find my clothes and run.
So while most guys my age were either married, getting all the pussy they wanted from girlfriends, or both, I went without except for masturbating with Mom's panties held up to my face. I loved her musty cunt smell.
The next time she asked me if Dad had been home, I asked her why she thought so. She said, "Nothing Honey."
"I am serious Mom. Did somebody rape you in your sleep?"
"I don't know. I was a mess this morning."
"Yeah Mom, I heard him in the middle of the night but I didn't get up." She seemed satisfied with the answer, especially when she found the big bag of dirty clothes that he left. His clean clothes were gone.
So was she saying that she only knew that she had been fucked if she found her pussy full of cum? This made me wonder if I could get away with fucking her. The next time would be my time.
A couple weeks later Dad came home a little after midnight and was gone by 2AM. I slipped into the master bedroom and found her lying nude on the bed. I started kissing her lips and her tits. It all felt so good. She moaned a lot but never woke up. I got a warm, wet facecloth and cleaned her up. I loved looking at her shapely legs and inviting mound, but my throbbing member reminded me that I was there to have sex with my Mom, not to ogle her.
That is when she started talking. I ran from the room only to realize that she was talking in her sleep.
When I crept back in the room, my Mom was playing with her clit and moaning while in a sound sleep. Her right, middle finger was going faster and faster on her clit and her left hand was massaging her breast. She was moaning louder and louder while pleasuring herself. Suddenly her body went ridged and she started shaking. As her ass lifted off the bed, her pussy nectar ran down between her legs. She let out a soft scream and rolled over on her side, still asleep.
Was Mom really asleep or was she faking because she knew I was watching her? Would she tell Dad? Besides, even if she was faking, how could she fake the juice oozing out of her pussy?
My first thought was to run; grab a pair of her panties and enjoy the heavenly aroma and the memory of Mom pleasuring herself all the while I would be jerking off. But I was glued to the spot. I watched as Mom rolled over to her back again with her legs spread wide apart.
I smelled her musty cunt and stuck a finger in it. Then two fingers. The faster I moved my fingers in and out, the louder she moaned until it was nearly a scream. I kissed her legs and crawled up from the foot of the bed until my face was hovering above her love slot. The smell of her sex was amazing. I started lapping up her juices while still enjoying her aroma. Then she pulled my head into her cunt with both hands. My tongue traveled up and down her slot and my lips nibbled her clit. This had been one of my fantasies for as long as I had been enjoying smelling her panties.
By then my cock was hard enough to break boards. Fear of waking her up was fighting with the desires of my member. The smell of her sex was driving me on. I moved up on her until the head of my love stick was pushing her pussy lips apart. Then I started rubbing the head of my prick up and down Mom's slot where my tongue had just been.
Then my worst fear. She seemed to be waking up and she said, "What?" As I ran out of her room, scared, I began to remember that my boxers were still in there on the floor. Now what should I do? Go back in and have Mom catch me or leave the evidence behind?
While sitting in my room, thinking about my next move, it made sense to give Mom time to get back in a sound sleep, and then rescue my boxers.
Creeping back into her room, while guided by her night light, the sound of her moaning greeted me. Her right hand fingers were massaging her clit again and her left hand was pleasuring her tit. Does she do this all night? And she still seemed to be asleep.
As my eyes focused on her cunt and the swelling in my cock made no attempt to recede, I had to rub my love stick on her pussy lips again. The head of my cock was all the way in and felt amazing.
