 Hi, friends I m Rahul.  I live with my mom and sis Anita and swati.  My dad
works abroad and comes once in two years.  We had gone for shopping we
bought clothes for us all had to.  Didi and Mom buy under garments so we
entered a shop mom and didi asked for a pair of bras and panties.  The
shopkeeper asked them for their size of their bra didi and mom answered 36d
40d the shopkeeper told them there are no such big sizes bra so they took
their panties and left the shop after hearing their breast size I became
horny and from that day I used think about their breast size and
masturbate. Let me introduce them to u.  Anita (46yrs) is a house wife with
40d cup size breasts and a well maintained figure 38-26-38.  she is
wheatish in colour.Swati(22yrs) is S.S.C failure three times.  She could
not get admission any of the colleges so she left studies and help mom in
the house hold works.  She has 38d cup breasts she is wheatish in color.  I
m 19yrs old boy who loves sex.  I m in the 12th standard I had failed in my
first prelims very badly .Mom and didi had lot of plans for me further so
they promised me to give a gift which I will never forget for my lifetime I
knew that they never give false promises so I worked very hard and acquired
63percent.Mom and didi were very happy with my success.  So that day after
my result I came running home.  I asked them for the gift they just smiled
among themselves.  That day both mom and didi had wore a deep neck
transparent blouse.  While talking I could see their cleavages clearly and
my rod had become hard rock.  I went and changed in my shorts.  Mom told me
to close my eyes and tied my eyes with a black cloth.  I could see a little
what they were doing Mom was removing niki's clothes she removed her bra
and panty her breasts were huge now mom told me "beta tere didi ne ek juice
banaiya aur aap ko yeh chusna hein." they threw me on the bed didi opened
her legs wide open.  I had never saw any lady pussy so close mom too
removed her clothes they thought I was blind folded mom started fingering
niki pussy niki brought it very close to my mouth.  I started licking her
pussy clean after this mom too gave me to taste her pussy after the session
they put on their clothes and dressed up.  mom asked me "rahul which juice
was better" I told them both were tasty and I wanted it every day.  They
agreed as it was my holidays We planned to go for a picnic on to the beach
and stayed overnight.  "Swati, please remove you brother's shorts...and
underwear, if he's wearing any." Swati looked at Mom.  "Swati, dear, did
you hear me?  I said 'please remove your brother's shorts and underwear!'"
Well, I had on a pair of swim trunks, and no underwear, and the thought of
what was happening was actually starting to get me excited again, so the
baggy shorts were beginning to tent in the center.  Swati, with trembling
hands, slipped her fingers in the waistband, and suddenly yanked them down
to my ankles.  My semi-erect cock stood out (but not up), and Mom and Swati
definitely stared at it.  "Very nice, now Rahul," Mom said, "please come
over here and lie across my lap!" I walked over to her, and got down on my
knees, and lay across her lap, exposing my bare backside to Anita and
Swati. Mom rested her hand on my muscular rear end for just a moment, and
then I felt her body move slightly, and a hard slap on my butt.  It stung a
little, but it smacked very loudly.  Swati jumped and gasped when she did,
but the thing I felt most was a surge of blood into my cock.  She firmly
slapped my other cheek, and I felt my erection growing, and bumping into
Mom's bare legs.  I felt the intensity with which Swati was watching my ass
as it got smacked.  After about ten smacks, Mom let her hand rest on my
bottom momentarily.

   Then she started rubbing.  "SWati, do you think you want a turn?"
"Well," she replied, "he's looking rather red, and I here has jumped with
every smack, but can't take my eyes off of his rear end, with his balls
dangling down...I think maybe its my turn!  Rahul, dear, will you please
come over here and get your sister ready?" I stood up, my erection firmly
"up" now, and swinging with each step.  Swati was wearing a one-piece suit,
so I knew that the only way to expose her cute ass was to remove the whole
suit.  I stepped behind her, and gently lifted the straps from her
shoulders, slowly peeling the material downward, giving everyone a good
view of her young breasts.  From behind, I got the first good view of her
ass, as the material moved to reveal the slice between her buns.  When I
had the suit on the floor, Mom sat down.  "Swati, dear, please come over
here, and let mom have a look!" Swati moved slowly over, and got on her
knees, and leaned over a rock.  In this position, her bottom cheeks
separated, and gave me (and Mom, too) a good view of her light red pubic
hair.  Woah!  She did have a great ass!  mom gently rubbed over my sisters
bare cheeks with her hand, and then smacked, pretty hard.  When she hit,
when let her hand linger for a moment on her skin, setting the spank, and
leaving a red hand print on her bone white cheeks.  If I had a hard-on
before, it was nothing compared to now.  I wanted to watch mom do this
about twice more, and then I wanted to plunge my stiff member into my
sister, from behind.  But, I knew that Mom was in charge, so I stood and
watched.  mom spanked Swati a few more good times, each time rubbing her
rear at the end of a smack.  After the fourth spank, I noticed that her
rubbing was dipping lower, and lingering longer.  I also noticed that
Swati's ass was wiggling with it, and really getting into the attention.  I
watched transfixed as mom finger finally dipped into my sister's now wet
(again) snatch.  mom's nipples were sticking out in the skimpy bikini bra,
and my sister's bare ass and cunt were now getting some serious rubbing
from my mom's fingers.  Out of the corner of my eye, I saw movement, and
noticed my mother moving and spreading towels on the grass beside the pool.
I reached over and untied mom's top, and slid it off, squeezing and rubbing
her breasts as she went.  This was too much!  My mother and my sister were
now getting hotter and hotter mom motioned for Swati to sit up, and when
she did, she immediately kissed her on the mouth, and I watched transfixed
as Swati's hand began to knead mom's breasts, and mom hand caressed my
sister's smaller ones.  When they broke their kiss, and mom stood up, I
reached down and slid mom's suit bottom down over her hips, revealing the
taut buns of a woman much younger than Swati's actually was.  I then turned
to my mother, and kissed her hard on the mouth, as my mother's hand's
squeezed my sister's fleshy buns.  As they kissed, I started pushing the
straps of my mother's suit down over her thighs, , giving me my first ever
sexual view of my mother's breasts.  Trying to forget whose they were, I
looked from the perspective of a yong man with a raging hard-on, and
noticed how nicely they were formed.  Gravity had had its effect, but still
they were well formed and she had dark nipples.  In my fingers, they
quickly stiffened as we two kissed one another with a familiarity that told
me that this was not an unusual happening!  Watching all of this, I had
started to rub my own cock for some relief of the tension.  Swati walked
over to me, now, and stroked my stiff member, too, and led me over to the
towels.
