Hi guys I am Kiran, this is my first story on FSI.
This is the story about how I had incest sex with my cousin sister while teaching her biology. This happened when I was in first year of engineering and monika was studying II PUC. During that time I used to masturbate around 2-3 times a day and would do anything for a pussy. I was a virgin and didnt talk too much with any of the girls in my college, so then monika came to my mind because, when we were small we used to go to our grand mother’s house in our school holidays, when my mom and aunt used to sleep in the afternoon we would play games in our home and one day my aunt and mom brought both of us pair of underwear we took bath and wore the new ones and in the afternoon we started playing again and after some time she raised her frock and showed me her underwear it was pink.
Then she said “show yours” I removed my half pant and showed mine then she looked outside
the room if somebody had woke up and then she said “we both have same ones” and asked
“can we exchange our undies?” I said yes, she removed hers and i couldn’t see anything
because of her frock and I also removed mine but due to my long T-shirt she too didn’t
see anything then we both handed our undies then suddenly she raised her frock then I saw
her pussy it was hairless and I could see the cleft from where her slit started, then she
asked”do you want to touch there?” I said”yes” from my childhood I was always curious
what could be in between the slit so I kneeled in front of her and with my thumb and
index finger I spread her pussy and I couldn’t make out what was in there as it was dark
then she asked me “Can we sleep over each other” I said “No” as I was afraid then we both
put our undies back, and after our holidays we came back and never talked about it and we
used to look at each other awkwardly whenever we met.
Now coming back, Monika had performed poorly in her I PU exams so my aunt and uncle
were worried about her studies and once when had went to meet her they scolded her and
told her to learn from me and my aunt asked me ” Can you teach her whenever you are free”
I said “no problem” then my aunt said “But don’t forget about your studies for sake of
your sister’s” then I came back to my home I was very happy that I will get a chance to
spend time with my sister. My aunt’s home was around 10 minutes ride on bike, my uncle
used to remain in home all the time and my aunt was a job holder who used to come back
home at 6:30 PM.
First day I taught her maths and as my uncle was in home I didn’t tried to seduce
her. This went on for one week and most of the maths chapters which she didn’t understood
were clear to her and on the next day when I went to her home I asked what she wanted to
learn she said “everything is clear to her except some parts of biology ” then I asked
“tell me which parts you don’t understand I will read them and explain them to you and
you do some other work because I need time as I am statistics student” she said ok and
started to show me the chapters to explain, I was shocked because she pointed at the
chapter which contained about human reproduction. She was quiet while pointing at it as
uncle was in home. Then she went back and started practicing something.
I read the chapter it was about prostate gland, sperms, ovaries, zygote and family planning.
After sometime my uncle said that he needed to meet somebody and is going to come
back around 10 in night I saw at clock it was 2 pm uncle said “If you are going to home
I can drop you” I said” No, still have some chapters left” he said ok and left home, we
both were alone in home now and while reading the book I came to know that my sister was
horny that’s why she has asked me to explain this and also she knew about her father
going outside. Now we both were sitting in the hall, I said “I have read the chapter and
I understood only a little as I am stat student so I will explain you whatever I know,
if you have finished your work I can start explaining” she said “OK, I will go to toilet
and come back” and then she came back and started closing windows, as some people were
standing outside. Then she sat on sofa beside me and I started explaining. “This is about
reproduction i.e how babies are produced, to produce a baby combining of male and female
sex organs is needed, when combined male sex organ releases semen inside female sex
organ which combines with ovaries of female and then baby starts developing”. Then she
asked”what is semen?” I said “It is a white fluid that is released from male sex organ
during sex” then I asked her “what do you call for male and female sex organs” she said
“tunni(penis in kannada) and tull(vagina in kannada)” she asked “why does semen gets
released from penis” I said “due to simulation” she said” Oh! who simulates it ” I said
“you dumb! it is simulated by you girls during sex” she asked “Then how girls simulate
it?” then I said”It can be simulated by many ways i.e through your vagina, mouth, hands”
“By mouth …….?” she asked i said “girls take the penis in mouth and lick it until
semen is released” she said” isn’t it dirty” then i said” even boys do it to girls” her
mouth was wide open when she heard it, then she said ” we pee from down there how can you
lick that” then I replied “nothing is dirty when it comes to pleasure”.
She seemed to agree with me then I told that I was going to explain about sex
organs in general, she nodded, then I said”male sex organ consists of penis,testis and
scrotum, penis is like pipe from which we boys pee and even semen also comes out of this”
she was nodding her head, I continued”each male has two testis where semen is produced
and they will be inside scrotum” she said”Ya I have seen kids sex organs”.
Then I started explaining about female sex organs, I said “female sex organs
are vagina where penis is inserted, its lips which look like slit, clitoris contains many
nerve endings which is used for pleasure” she asked “is it the one which is hidden below
lips?” I nodded my head she said “I feel tingling in my stomach whenever I touch it” I
came to know that she has completely turned on, then I asked “have you ever orgasmed?”
she said “No, I don’t know what is orgasm, but whenever I keep on rubbing my clitoris I
feel like tension building up in my stomach I get scared and stop rubbing it”.
I said “OK now let’s see about family planning” after a affirmative look on her
face I said” family planning is about having pleasure of sex but not getting pregnant”
she asked eagerly”How is that?” I said “by using condoms and some other device called
copper-T, condoms are like rubber shield worn on penis which prevents semen but female
cannot feel the warmth of hot semen” she said “what’s the point when you cant feel
pleasure in tull(pussy) aren’t there any other methods?” then I said” you can use i-pill
or you can have sex after your periods around 5 days without having protection” she was
delighted to know all this.
Then I said “let’s conclude if you have any doubts then ask” she said “what does
penis and semen look like” I said”I have told you earlier and haven’t you said you have
seen kids penis” she asked “can you show your penis?” I said “it’s wrong” she said “you
are just teaching me and how can it be wrong” I said ok and got up and by then there was
a large wet spot on my pant and she asked “is it pee?” I said”its precum it comes from
penis whenever we are excited just like your pussy” she said in a playful tone” so you
are excited, my tull(pussy) is also drenching even my skirt is wet, now remove your pants
I want to see it” I said”ok now on you can call your tull as pussy and my tunni as cock”
she nodded and I slid down my pants along with boxers my cock was completely
erect and I have it of decent length of 5.9 inches. Monika’s eyes lit up when she saw my
cock and she exclaimed “its huge!!!! and hairs are so tiny” then I said “its of average
size, other guys claim to have bigger than this and I have trimmed it” she asked “can i
touch it?” I agreed, then she gripped my cock and said “it’s very warm” she left my cock
and squeezed my scrotum in her right hand, I squealed in pain and cried “be gentle with
the balls” she nodded and started caressing my balls gently and said “these are heavy” I
replied”they are filled with lot of semen” then she asked “can you show me your semen?” I
was very much turned on by now and wanted a release very badly I said “ok, but this place
will be complete mess as there is lot semen developed in my balls due to all this sex
talk” she asked “will it be that much?? and how many times can you release it??” I said
“my sweet little sister, I release it only one time but if I consume viagra I can go on
for two to three hours” she went inside her dad’s room and brought some capsules and
asked”are you talking about this?” they were viagra capsules by some other name, she
said she saw every night her dad taking those pills so she brought me them.
I said “bring me water” she brought and I took out one capsule she said “Not one
take three mom and dad have went relatives funeral they will come tommorow night, they
had texted me and I want you to release your cum all day for me”
