Originally I when I stated to write this I was going to give the readers the power to decide by ratings and comments if this should be a one off story or do more parts after it. However I just could not stop adding to it. More and more ideas kept popping in my head and I just kept typing. So in short I do not know still if this is a one-off. We will see how it goes. Again power in the readers hands.
Turning It Off
"Do you think I would turn it off if I could? Just does not work that way."
"Try! Try hard! Donna this is not normal!"
"Robert! Normal? Normal you say? What is normal about the things you like to do in bed with me. Having me on my knees as you face fuck me. Spending all that time with that long dildo so I can become accustomed to being throat fucked. That is normal?"
"Well yes. At least that is not illegal."
"Legal. Fuck that. This is my home, okay our home. What happens in our home is our business. Who will it hurt? If he is willing, then anyone that has an issue with it can go fuck themselves."
"Look, honey I would do anything for you; you know that. But this. Technically it would be cheating and on top of it well in my opinion not normal."
"Bah!!! Normal. I seen the way you look at our daughter when she walks around in her bikini. When she is lounging around the house in a sports bra and spandex shorts. They are so short her butt cheeks hang out. You are no different from me than you think so. So what if I want to fuck our son. Is that so wrong? It is within the family. At least I do not want to fuck some other guy outside our family."
The mother continues to say "Look honey I been dealing with this since childhood. I have had the same desires as when my father was alive, and when I was living in my parent's home with my brother. My brother was a hunk. Yes, he was no athlete but with all the calisthenics he did in his room he had a nice body. Our son is just like him."
"Look I get it. We all have our fetish, but some just should not be acted upon. There are those with some disgusting illegal fetishes that I will admit are far worse than incest but still, this is incest."
"Look Charlie, you are either on board or not. I am done trying to fight these feelings. The fact is if Chuck is interested, then I am going to suck and fuck our son's cock. Just how it is going to be. Either accept it or leave me; either way this is going to happen which again depends on if Chuck is into it. Also honey if you wanted to fuck our daughter, I would not stop you. Hell, I would watch and even take part."
"I need to get out of here. I am going for a drive. Chuck is home and our daughter is out with her friends and will not be back in the wee hours of the night. In fact, I am going to stay in a hotel tonight. You want to fuck him, then go ahead. But I do not want to hear a single thing about it."
"Fine with me. Just need to take a shower and cleanup my pussy a bit with the razor. Then I will be sitting on Chucks face as he eats his mother's pussy."
"Oh yeah that is assuming he will be interested in fucking his mom."
"Oh please...I see how Chuck looks at me. He will not be able to stop himself, this I am sure of." Mother continues to say, "Go! Pack a bag and go. I will see you tomorrow. Besides when you get back, I am sure after you think about what is happening while you are gone you will be so turned-on you will be more than happy for me to let you throat fuck me. So, go. I need to get ready."
Chuck's father grabbing a travel bag throws in some essentials and storms out of the house.
But what Chuck's mom and dad does not know is that Chuck was listening the whole time. With cock in hand and his ear to the door Chuck finds his dream will come true.
The fact is Chuck wants to fuck his mom, even his sister. Both are sexy. The sister is obviously hotter due to being 19 she has a body you cannot help but stare. Mom on the other hand has this MILF thing about her. She is not some blonde goddess like people imagine or jerk off to but quite the opposite. She is a brunette with an hourglass figure. Chuck's mother is not shy about walking around in very little clothing. Now hearing their conversation, Chuck cannot help but wonder if she wears such clothes to entice him.
Either way mom not only has a body that her son finds appealing and so does his friends who commented how she turns them on, but she is also has a motherly face. And the best part is when she has her librarian type glasses on; let us just say Chuck must leave the room while she is reading her book to relieve himself, so she does not see how hard he is.
But now hearing their conversation their son need not to worry. Turns out his mom is just as interested in him as he is to her. Not being stupid to pass this opportunity up. Just need to do some prep work and a little plan of his own.

Several minutes later...
Chuck sneaks back to his parent's room and pauses. Not hearing a sound, he nervously turns the knob and slowly inches it open. Using the mirror angled perfectly he sees enough of the room that is mom is not in there. That must mean she is in his parents' personal bathroom.
At first Chuck thought of laying on the bed naked but then had a better idea. Risky if he did not know what he knows. But he does know his mom wants to fuck him. Finding a perfect place to hide with a hard-on ready to go Chuck listens to the shower running as he anxiously waits.
Minutes goes by which feel like hours and finally his mom turns off the shower. Not able to help himself he peaks slightly out of his hiding space to see just enough into the bathroom. Watching his mother dry herself off she then hangs up the towel and starts exiting the bathroom.
Unknowingly passing her son Chuck makes his move. Using one arm to grab her around the waste, and the other on her throat he startles his mother. Not giving her a chance to react using much force pushes his mom to the bed resulting her falling or more like bending over the end of the bed.
Without a bit of hesitation Chuck aims his cock into his mother's wet hole and enters in with force. Then grabbing her by the waist Chucks pounds his mother with everything he has. His mother Donna reacts with grunts and moans and gripping the sheets with her hands. Her fingers turning white from using such a tight grip his mother is on the brink of an orgasm.
Not usual for Donna to cum so easily and quickly; usually she needs her pussy eaten with a lot of attention to her clit to get her off. But today probably because it is her son Chuck that is fucking her that changed that. Assuming it is Chuck; hoping it is Chuck. Either way she cannot help herself and just as she is about to cum, she opens her hands, pushes up on the bed in a Yoga Cobra like position to which Chuck grabs his mother by the hair and pulls her head back.
Hearing his mother screaming so loud that the neighbors can hear and feeling the grip on his cock he can clearly tell his mother is having an orgasm and Chuck is not far behind.
In the last few pumps Chuck grabs his mother again by the waist and with one final push he pulls her tight with her ass pressed against him and too grunts and moans so loud that the neighbors may come knocking on the door to ask if they are okay.
Mom and son are okay, better than okay. They both just had an orgasm for the record books. With Chuck and his mom catching their breaths he pulls out his cock and looks down looking at his mother's pussy close shut but does not stop his load from dripping out of her.
After a few minutes, his mother pushes herself off the bed and turns to her son and said, "Thank You!" Then kisses him on the lips then walks back to the bathroom to flush out her pussy.

Several hours later...
Around 11pm Chuck and his mom Donna are laying on top of the mattress cover covered in sweat and bodily fluids. After the first time Chuck took her and the mother flushed out her pussy they sat and talked. Then went from talking to kissing, and then from kissing to sucking, eating, and fucking...more than once but several times till about 11pm where they wore each other out.
Donna looking over to her son and said "Honey, I love you so much so do not be upset when I tell you to go back to your bed. Do not get me wrong I would love to cuddle and fall asleep with you on the bed but if your father finds us like that, I do not know how he will react. He is aware of this was going to happen as you clearly know when you told me you were listening at the door. But regardless, I do not think he is ready to be face-to-face with it. At least for now."
Kissing her son he does not say anything and slips off the mattress and heads over to his room and by the nick of time. As Chuck was about to enter his room, he hears someone fiddling with the front doorknob. Being concerned if it is a robber because his father was not expected by morning, he peaks from around the corner finding his sister stumbling into the house obviously shit-faced drunk.
After she barely made it through the door, she almost collapses which with Chuck quick on his feet catches his sister. In the position she is in facing her brother with her arms around his neck she looks down and says "Ummm...hiccup.... why are you naked?"
Chuck replies "You would not believe me if I told you. Let me help get you to bed before mom sees you like this."
"Oh, my big brother is taking his sister to bed completely naked. Are you going to take advantage             of me being that I am so drunk I will not remember this in the morning?"
Chuck thinks about this for a second and goes from a straight face to a grin.
Using all the strength that he has he lifts his sister in his arms with her wrapping both of her arms around his neck she says, "Oh my...my hero is here to save his sister from mom....hiccup....god I am drunk!"
After carrying his sister to her bed, he gently lays her on top of her covers. Taking a moment to take her in she is wearing a crop top, clearly no bra, and her skirt is so short and loose that with her legs spread as they are Chuck can clearly see that she is not wearing any panties. He also takes in that his sister has a landing strip not bald like mom.
While he knows this is wrong, but since he already fucked his mother Chuck decided to get a little taste of his sister. Granted he has fantasized about this before but never thought an opportunity such as this one would ever happen in real life.
Not thinking with the right head, Chuck positions himself between his sisters' legs. Using both of his hands he spreads her lips apart while leaning forward with his tongue extended; he takes a lick from the bottom to the top of her slit where then he hears his sister moan. Taking this as a sign of approval he continues giving his sister much needed oral pleasure. At least that is what he thinks seeing how wet she was before he even started.
Getting wetter by the second Whether Amanda is aware of who is going down on her or not, she reaches for Chuck's head and pulls him closer, smothering him with her pussy juices. Having the time of his life Chuck thinks back when this all started. In one evening, he first had his mom, now his sister. "Life cannot get any better than this" he thinks to himself.
Chuck is slurping it all up and while doing so uses his finger from his right hand and puts it in his sister's pussy. Getting it nice and wet Chuck pulls it out and slides it down from pussy to taint to her butthole. Using a little pressure Amanda's ass accepts the intruder and grips his finger.
Hearing his sister say, "Oh shit...fuck yeah finger that ass!" Chuck does just that. Shortly after pumping his finger in his sister's ass Chuck sucks as hard as he can on his sister's clit and starts flicking it.
