 My mom started acting different about two years ago.  It was just small
things like a pat on the butt, or she started giving me kisses when ever I
did something good.  Nothing big but it just seemed a little different. 
Then she started doing stuff that would make me a little uncomfortable. 
She would "accidentally" walk in on me when I would be changing and when I
would do something small like put a glass in the dishwasher she would give
me a kiss almost on the mouth just for doing that.  Then she started doing
really big stuff and it only got better.  One day I was setting by my self
my mom was up stairs washing the dishes, everything was normal.  She came
down stairs and said to me "I just saw this thing on TV that said teenage
boys are getting desires on their testicles and they should check to see if
anything seems different." I said "thank you mom for telling me.  " and
told her I'm busy and to leave me alone for a little while.  she looked at
me and she almost looked upset.  I went to sleep that night and was
awakened to find my mom touching my penis.  I didn't know what to say and
she looked like she didn't know what to say, but then she said " I was just
checking to see if there was anything wrong with you testicles, because I
know you don't do what I tell you to do" the n she gave me a kiss on the
forehead and told me to go back to sleep, and she left the room.  I was
going crazy, my cock was the biggest I've ever seen.  I just thought to my
self "was it because of my mom" but then I just thought it was because she
was touching it and it maid it big.  The next morning I went down stairs
and my mom was at the table.  "I was just seeing if there was anything
wrong" I told her "I understand" and then she said something I couldn't
believe.  She said "You are becoming a big boy" and she had a grin on her
face.  I was speechless I just kind of looked away, then she just got up
and left the room like nothing had happened.  I secretly liked what she had
said and it made me feel good.  It was strange because I started looking at
my mom differently.  My mother is about 5'6 and I am about 5'11.  She is
41, She is kind of bigger, not fat, she has thick thighs and a nice big
butt.  her tits are a little large, but nothing really to special.  She has
beautiful hair (she always likes to look her best).  I started having these
strange feelings.  Like this one time I was masturbating and nothing was
really working, and then I thought to my self "should I try masturbating to
mom, why not it will be like an experiment" so I started thinking of me and
my mom having sex.  My dick became almost has big as it was that night my
mom was touching it.  Then I just started thinking to myself "should I be
having these feelings" but then I said "fuck it, I don't care." Nothing
really out of the ordinary happened after that until I had my accident.  I
was skateboarding and tripped and broke both of my wrists.  I was in the
hospital for a very long time because the doctors said I shattered both of
my wrists, and I would have to have on two casts for a few months.  I
didn't think it would be that bad at the begging, but it became horrible I
was not able to do something that I used to do all the time, masturbate. 
After two weeks I was going crazy, I tried everything, but nothing would
work.  On e day I was trying in vain to masturbate.  Then all of the sudden
I see the door open and my mom walked in.  She looked at me and gasped, I
was so embarrassed.  Then she started grinning and said "you poor baby, it
must be hell for you." then she came and sat down by me, and said something
that I wanted to hear for the longest time "Would you like me to help you
out" I grinned and said "yes please" and she said "You know I would do
anything for you, you just have to ask" and she started running her fingers
up and down my cock.  Then she started jerking me off.  I was just looking
at her and she was looking at me and we just started kissing, are tongues
where going all over one another.  At this time she was moving her hand up
and down as fast as she could.  I was getting ready to cum and god did I
cum.  I cummed all over my mom.  She just said "I'm glad I could help you"
then she gave me a kiss on the lips and left the room.  The next morning I
found a note that said "I'll be back later, had fun last night.  Love
mom.". All day I couldn't stop thinking about last night.  Then She came
home and I ran up stairs.  "Mom I couldn't stop thinking about last night,
would you do it again?" she said "You are a good boy, I will do that
anytime you want" and I was just looking a her thinking how good looking
she was.  She had one a nice skirt and a shirt that showed off her tits.  I
said "could we do it now" she said "sure, but lets just try something new"
she unzipped my pants and started robbing my cock until I got a bonner and
then she got on her knees and opened her mouth and started licking my cock
up and down.  She was started sucking on the head of my cock.  her tongue
was just rolling around the head of my cock and she seemed to be loving it
as much as I was.  then she started sticking the entire thing down her
throat and my cock is about 7'1/2 inches.  She started nibbling up and down
my cock.  Then she went back to sucking.  We were going on 10min and then I
finally came, wave after wave of hot cum in my moms mouth.  Then after a
few minutes of silence my mom got off her knees and said "I can't wait
until you are able to fuck.  Your father could never go for very long.  Now
that he is dead I haven't gotten any for almost 3 years, will you fuck me
when you are ready." I said "I would fuck you right now if it wasn't for
these damn casts" she gave me a big hug and went to go take a bath.  We did
that almost every day for two weeks, until the day that I was able to get
my casts off.  I was looking forward to that day because I would finally be
able to pleasure my mom like she has been doing for me.  When I was driving
home with my mom I said "today we are finally able to fuck" she just
grinned and nodded.  We got home and we became almost like animals.  We ran
to my moms bedroom and got naked as fast as we could we just start kissing
and licking each other.  Then I started fingering my mom's wet pussy and
she started moaning.  Then I started licking her tits.  Then I stopped
fingering her and spread her legs and jammed my long shaft into her and she
started moaning.  I was going back and forth, I started licking her tits
and she started screaming "FASTER!  FUCK ME!" I started going as fast as I
could her pussy was so wet and warm it felt so good.  At this point she was
screaming "I'm going to cum!" but I wasn't even close to being done all
those times my mom would give me head maid me able to go for along time. 
She cummed I could tell because I got really wet.  Then I turned her over
she asked what I was doing and I told her "I have always wanted to try
this." I stock my cock as far as I could up her asshole.  She started
screaming "OOOOHHHHHH, I have never felt this good!" I was going as fast as
I could and I started slapping her ass.  I pulled my cock out of her ass
and jammed it back into her pussy.  I was going, and cummed what seemed
like it was a gallon of cum in her.  After she looked at me and said "you
are the greatest I came two times.  I want to fuck you every night" And we
have done it.
