Made My MOM a Slut

This all started when I was 14 yrs old.
We had a dog max which was a black lab about 5 yrs. old, He was a great dog and always very friendly.
My mom is 5′ 7″/about 140lbs/short black hair with big brn eyes/with a model type face with big eyes, nose and mouth, lips etc, if you know the type?
She is 38d-26-38, with extremely long thick nipples! Pink nipps that were almost impossable to hide even with a bra.
My mother had been div. for some years, going thru a number of boyfriends.
We were living in a 2 bedroom apt, in a huge complex, we each had our own bathrooms, but our bedrooms shared a wall, which were quite thin!
I would hear her getting fucked by her bfs, So I could tell which ones were good and which ones werent so good.
She was always quite vocal, so it was easy to hear and know the level of her excitement.
The last bf really made her loud and I could tell she was having the best orgasms ever!
Well her bf got a new job that involved alot of traveling, I could tell when he would be gone for 2-3 weeks at a time my mom would get VERY horny!
One weekend mourning I got up to find her dressed in a blue very thin cloth robe.
I then notice that this robe buttoned all the way from the floor to her neck, but she had it unbuttoned from her neck down to just the top of her breasts, and unbuttoned from the floor to just below her pussy!
I was pretty shocked by this cause I could tell she wasnt wearing a bra! Her nipples were very very visable to me, then when I saw her bending over I relized she did not have any panities on either!
This made my dick extremly hard right away and she did glance at it a time or two.
I jacked off like 3 times that night thinking about her!
The next day we were out shopping, food etc, and stoped at a 7-11, I asked just on a whim if I could buy a pethouse mag, My mom smiled at me and said sure go ahead.
From then on I was a porn addict, I LOVE PORN!!!
Anyway this went on for about 2 weeks, there was more of seeing her in the robe, she was showing more and more clevage to me, stiing down with legs apart so if I looked I could see her cunt hair etc.
The I started letting her catch me with a hard-on, that first time was something, she walked into my room one sat.
