Sister in law
by sheepisheyes

My sister in law (wife’s sister) is very aggressive and very attractive.
She has said in front of me that my wife could have done a lot better. She
does not have any respect for me and thinks I am a loser. Which of course
she is right. Somehow she has a wanker radar and seems to know I am a chronic
masturbator. I don’t know how she knows but I have met other women that seem
to also somehow sense I am pathetic and masturbate all the time.

Of course my sister in law, Nancy makes me feel inferior and pathetic
which just makes me want to masturbate even more. Its a downward spiral
when she comes to visit. I am sure she knows this and tries to turn me
pathetic so she can point out to my wife what a loser I am.

Nancy also has a habit of letting me see her panties. This is my wanker
weakness. She always wears short little skirts and dresses and sits across
from me. She will open her legs just long enough for me to see those lace
white panties. Again I am pretty sure this is on purpose so that I will run
off and play with myself.

I am in a sexless marriage. My wife stopped having sex with me years ago. She
said I just don’t get her off. She knows I am a chronic masturbator and allows
me to play with myself in front of her at times while she mocks me. I don’t
think she is cheating on me although I told her she could as long as she
tells me about it. I am just too pathetic and not a real man for her. She
needs to be taken and fucked which is something I am not capable of. My lot
in life is playing with myself and feeling pathetic.

Nancy came to our house to visit. It was warm weather so of course she had her
short little skirts. She’s petite with nice breasts and ass. Just hearing her
talk in her commanding voice makes me feel inferior. She will right away
make fun of me and I of course will take it and start feeling horny. I don’t
know if my wife has ever told her that we no longer have sex but I’m guessing
Nancy at least senses it. She is always trying to get my wife to go out at
night and leave me home.

On this visit the 2 of them were going out of town to see their parents for
a few days leaving me home alone to play with myself. After they left I noticed
that Nancy had left a pair of white lace french cut panties laying on the
bathroom floor. She is so evil. This had to be on purpose I just know it. The
first day I ignored them, but then I just got to feeling so pathetic and
helpless. I just had to go into the bathroom and look at her panties.

Of course being a chronic masturbator the oppurtunity to play with myself with
my sister in laws panties was about as pathetic as it gets. So loser me got
out my vaseline and started stroking while sitting on the floor looking at
her panties. Then I had to pick them up and smell them. I needed to be
careful not to get vaseline on them. One sniff and I started shooting my goo
which landed on her panties. At this point I didn’t care and I just let all
of my cum land into her sexy little panties.

I figured I had a couple days for them to dry and she wouldn’t notice. But of
course the next day I did it again and the day after that. Each time I knew
I was increasing my chances of getting caught and that just added fuel to the
fire. I kept imagining her noticing the panties soaked with my cum and thinking
what a pathetic loser I am. There was no stopping now.

They came home that afternoon and when I walked past the bathroom I noticed
her panties were gone. I instantly got hard and could not even look her in
the eyes. During the day she did not say anything but something in her face
when she looked at me told me that she knew. Kind of a smirk and a knowing
smile. I wanted to run upstairs an start stroking.

That evening Nancy and my wife were sitting in the living room watching TV.
I sheepishly walked in the room and sat down. They both looked at me and
that’s when I noticed her panties sitting on the coffee table.

After seeing the panties on the coffee table I looked up at my
sister in-law and my wife. I must have turned 8 shades of red. I didn’t
even need to say anything, my reaction made it very obvious that I knew
why the panties were there. My wife said “I think you need to go and
wash these by hand and then come apologize to my sister”. Nancy just
looked at me with a smirk and shook her head in a condescending way like
I was a bad little boy.

At this point there was no denying it, not to mention I was incredibly turned
on at the utter humiliation. I could feel myself getting hard as I stood there
looking at the floor. I reached over and picked up her delicate lace panties
which made me want cum in pants right then and there. I quickly went upstairs
and started hand washing her panties in the sink. Just the feel of her panties
in my hands made want to jerk off again. I couldn’t believe how pathetic I felt.

I finished washing her panties and dried them as best I could with a towel. I
then hesitantly went downstairs and entered the living room with her damp panties.
I then handed them to Nancy. She reached and took her panties, my wife then said
“What do you say to Nancy?”. I looked down and turned red again and said I was
sorry. My wife then said “Tell her why you are sorry”. I couldn’t believe I had
to say it. I was so incredibly turned on. They could both see I was hard and felt
so helpless in front of them. I then told her I was sorry for masturbating with
her panties.

The humiliation was over powering. Nancy then told me she left her panties there
on purpose and bet my wife that I would jerk off on them. She told me she knew
what a loser I was and wanted to prove it to my wife. My wife asked my how I
could be so pathetic as to play with myself with her sister’s panties? All I could
say was I was sorry. My wife said “You are not sorry at all! You’re so pathetic!
This is why I don’t have sex with you anymore”. Now my sister in-law knew for sure
that my hand is my only sex life. I didn’t care anymore. All I wanted to do right
then was play with myself.

Nancy then said “I also made a bet with your wife that I could make you play
with yourself in front of me”. I just stammered and could not say anything. It
was exactly what I wanted to do though. “Prove to your wife whether you are real man
or not.” Nancy said and laughed. My wife said “Go on upstairs and get your Vaseline
I know you want to”. I had no choice. I was about to change everything. Nothing
would be the same. Nancy would forever lose all respect for me. My wife would lose
what little respect she had for me. I would be the most pathetic thing I have ever
done. God I was horny.

Of course I hightailed it upstairs and grabbed my Vaseline. I was literally shaking
when I walked back in the room with my little jar of lube in my hand. Nancy laughed
out loud “I thought so. You’re not a real man. Just a pathetic masturbator”. I just
shook my head yes and look down. My wife said “Well then Go for it”. The sweetest
words for my ears. As embarrassing and pathetic as it was, it felt exactly right
that I should show these two women that I was not a real man.

I dropped my pants and underwear, and sat on the floor with my legs spread apart.
They just sat and watched and laughed. I dipped my finger into the Vaseline and
took a huge scoop of it. I then grabbed my penis and coated it. The sound was almost
obscene as I started stroking. Both hands were covered with lube now as I grabbed my
balls with my left hand and stroked madly with my right. They watched me as the sloshing
sounds got louder.

The look of amusement on their faces was almost too much.I slowed down a little because
this needed to last, it was just too hot. As I pathetically made a complete spectacle
of myself, Nancy stared right at me and slowly started to part her legs. She asked
if I would like to see her panties again as the perfect white triangle between her
legs came into view. I could see the black hair of her landing strip through the lace
fabric.

That’s was all I could take, I spurted ropes of cum onto my shirt and the floor. I
could not believe the amount of cum, I was so turned on. They both started shaking
their heads and laughing out loud. They started mocking me for being a loser and
a panty sniffer. I was way beyond caring anymore. I wanted them to know who and what I was
and make fun of me. My fate was sealed. Nancy said to my wife “Looks like I won that bet
and its time we found you a real man”. My wife nodded her head and said “Yes its time”.
