Aunt Joyce had gone from a simple older woman that was content with sitting at home, reading a book to where she wass now.  There is where I came along, with my fertive desire to stick my hard rod into her  honey pot.  I had been wanting to fuck her for the longest time, but how do you approach your aunt and ask her if she would like to have sex?  I can't think of a way; but the opportunity presented itself and I went for it.  When I first slid my  hard cock inside her unused pussy, she didn't know what to feel.  At first, I'm sure that it hurt- with her vagina not having any action for many years.  But then, I suppose all the feelings that she used to have whenever her husband used to plow through her cunt, came back to her.  You could tell the moment that it started feeling good, because she began to shiver with every lunge of my dick inside her.  Then, she began to let her emotions take control of her body, and she began to move her large body in order to meet my undulating cock.

She shouted that she couldn't believe that she had missed this feeling for all these many years.  But, then something happened that would change both of our lives- a dog named Pounder.  I had this crazy and wild idea that I would love to see Aunt Joyce getting fucked by a dog.  Just the thought of this possibility gave me the hardest erection that I have ever had.  "Yeah, I would love to see her being fucked by a rapid fire dog's cock- with it banging her ass as fast as he could go", I thought to myself.

Well, I devised a plan where I would be in the bed with Aunt Joyce, fucking away and bring Pounder onto the bed and let him take over my place in her fucking.  This plan did more than work- it screwed up our lives.  In the process of fucking her, I patted my leg to signal Pounder to hop up on the bed- which he obeyed to the tee.  As I quickly moved over, Pounder began humping Aunt Joyce with a desire that I had not ever seen.  At first, she  knew that something was up, and, in fact, scolded Pounder to get off her, but to no avail, because Pounder just kept up his rapid fucking of Aunt Joyce's large pussy.

After several lunges from Pounder, she began to feel the incredible sensation of having  a 10 inch dog's cock sliding quickly in and out of her vaginal entrance.  Aunt Joyce began to shout at the top of her lungs, "FFUUCCKKK  GODDAMNIT!!!!  UUUUHHHH  AAAAHHHHH He's so big inside me!!- but it feels so good!!  This is the best feeling that I have ever had!!  OOOHHH  SSSHHHIIITT- I can feel his cock getting hot.  I think he is going to cum in me.  OOOHHH YYYEEEAAYY  Here it comes- FUCK, his cum is

hot!!!  OOOHHH YYEEAAHH!!!

With those few words, Aunt Joyce had just become a dog lover.  She got to where she would no longer fuck me, but wanted Pounder, instead.  I had no one to use my horny prick on, except on the floor, while using my hand.

Each day, you could hear Aunt Joyce and Pounder fucking like there was no tomorrow; however Pounder got to where he wanted to fuck Aunt Joyce almost all the time.  They would have just completed ttheir sex act, and then 15 minutes later, Pounder would come over to her and begin sniffing her crotch and trying to get her to get on all fours so that he could fuck her from behind.  Finally, Aunt Joyce began telling Pounder "NO"; but this didn't sit well with him.  He would try again, and again she would turn him down.  Finally, Pounder would hop down and sort of growl at her, because of her rejection.

Aunt Joyce would ask me how to solve the situation, and all I would do is laugh and tell her that it was her problem and she had no one to blame but herself.  Of course, this pissed her off; but I was just standing aside and letting her deal with it herself.  It got to be somewhat ugly, with Pounder sometimes getting some pussy and other times being told "NO".  He got to where that if he was told "NO", he would begin to bellow this low growl and bare his teeth.

Aunt Joyce got to where she was afraid to turn him down, but there were times that she was so red and sore from Pounder's fucking her that she had to say, "NO"  The situation got to where Pounder would  bite her on the neck and claw her with his front feet if she turned him down.  He was becoming extremely violent, and she didn't know what to do; she was afraid to turn him down for fear of getting really hurt.

The next day, the door bell rang and to Aunt Joyce's surprise, it was her daughter, Dawn.  She had not seen her in almost two years, so both of them were excited to be together.  Dawn (who was 38) was down to spend a couple of weeks with her mom.  At first, Aunt Joyce was tickled to have her daughter home with her, but then she realized the major problem.  What about Pounder?  

He will want to continue his fucking and for God's sake, she couldn't let Dawn know what had been going on between them.  That's all she needed- to tell her daughter that she had become a dog slut.  That would go over well.  Maybe if she just closed and locked the door to her bedroom, maybe that would half-way take care of the problem for tonight.

At 11:00, we all went to bed, with me sleeping in a separate room, Aunt Joyce, in another room, and Dawn, by herself in the third bedroom.  Just as I was about to doze off, I heard Pounder howling about the fact he could not get into Aunt Joyce's bedroom.  He was making an extreme pest of himself, with all the howling and growling and whining he was making outside the door.

Dawn spoke up, "Mom, why don't you let Pounder in your room, so we can all get some sleep?"

Aunt Joyce couldn't tell her daughter the truth, so she told Dawn that he was such a pest and would be hopping on and off her bed, and would be constantly bothering her.

"Well, at least some of us would get some sleep", Dawn replied."

"You don't understand", Aunt Joyce    said.

About that time, Aunt Joyce heard Dawn get up and open her door.  Pounder happily ran into Dawn's room and began wagging his tail.  It seemed that everything was back to normal, but boy was I wrong.  Within a few minutes, I could hear Dawn's voice asking Pounder, "What do you think you are doing.  Get your nose out of my crotch!!  Stop licking me there!  You need to get off this bed.  What is that thing?  OH MY GOD!! What a cock!! NO NO !! Don't put that thing in me!  OWW  That hurts.  STOP THAT!!  QUIT! GET OFF ME!!"

Next, you could hear a low moaning coming from Dawn.  "OOOHH OOOHHH- OH YEAH!!"

You could hear Dawn's voice as it got louder and more excited.  I had to slip out of my room and see what was going on with Dawn and Pounder.  I got out of bed and eagerly approached  her bedroom and, with it being dark, I had to allow my eyes to get adjusted to the darkness.  As my eyes began to adjust to the darkness, there was Dawn on all fours, with the dog behind her, with his ass firing his swollen cock into Dawn's aching pussy.  She was, by now, screaming at Pounder, to fuck her hard- that it felt so good.  With Pounder's every lunge, Dawn would back her ass up so that she could feel the entire length and girth of his cock.

While I was standing there watching, Dawn saw me, but she couldn't speak- her body was shaking and trembling so bad.  The only words that I could make out was, "Please don't tell."

I thought to myself, "You're going to fit right in."
