Brother Loves Married Sister’s Big Lactating Boobs

Recently, I started reading stories on this site and became a fan of them. This is going to be my first story writing here and every single incident that happened in my life with my sister will be portrayed.

Since these are real incidents, I am going to change the names of the persons involved in their privacy. This series of stories is going to be a little long. Please be patient while reading them. Please bear with my writing skills as I am new to writing stories.

The family consists of daddy Vasu 54 years, who is an officer in the government sector, mom 52 years, who is a housewife, Son (me) Sri, 30 years old, and my sister Priya who is 28 years.

I am Sri, 30 years old. I am an average guy with, fair complexion with a penis of 6.5 inches. I have been a horny guy since my teenage. I started masturbating when I was quite young. I started watching porn and fantasizing about girls while fucking.

I was always curious about a woman’s body. This incident happened at the age of 28 while I was working in a private company but from home due to the lockdown.

My house consists of 1 hall, kitchen, 1 bedroom for me and 1 master bedroom for my parents. Generally, I will sleep in the hall when my sister comes home or anyone comes to my home as I have a single cot bed.

Now let’s jump into the story. I shall tell you how I explored incest sex with my sweet sister. My sister’s name is Priya. She has 34C size boobs (mainly because of my constant play with her breast..ha-ha) with a good figure and an innocent face.

My sister had got married 3 years back and had a happy married life. Now, my sister was pregnant and she came home 6 months ago for her delivery. I was seeing my sister after a long time of nearly 18 months, and even after her marriage, I hadn’t seen her.

On the day of my sister’s arrival, I didn’t go to the office so that I could see my sister and brother-in-law.

When they arrived, I saw that my sister had changed a lot in her physical appearance. I welcomed them at home and then we were in the hall chit-chatting and exchanging stuff.

After those 2 days, my brother-in-law went back to his house. Because of pregnancy, my sister used to wear loose t-shirts, nighties, dresses, and sari. At home in general, she used to wear a t-shirt with pants, sarees, and nightwear.

A few months continued like this. I was going to my office regularly for meals while she would share all the love stories of her neighbor and the fighting of husband and wife in and around neighbors.

We were like friends more than siblings and I would share all my colleagues’ stories. During the day she used to work in the household with light work to help my mother.

We used to have food in the hall because we don’t have a dining table. All the bowls are brought to the hall and kept on a tea-poy. During that time, my sister used to help bring the bowls.

One night while she was bending to keep the bowl, accidentally I saw her cleavage! Then again while she bent to take food or serve the food, I could clearly watch her cleavage.

My sister’s round boobs were in the shape of perfect balls and her nipples poking through her blouse made my mouth water. Seeing this, a tent formed inside my brief. She noticed my glances at her. There were multiple times where she caught me looking at her breasts.

I was becoming very horny. Immediately after lunch, I went to my bathroom and masturbated thinking of pressing my sister’s right boob that would perfectly fit in my hand and sucking her left boob and biting the nipple like a small child. Finally, I released my cum in the bathroom. After that, I went to the hall to sleep.

The next day when I woke up in the morning, I saw my sister sweeping the hall by bending in the same nighty. And again and every time she bent to sweep the floor, I could see her boobs sway left and right. This made my dick automatically rise (It was very hard to control!!) and form a tent in my brief.

My sister came in front of me and continued sweeping. I was looking at her round boobs with big eyes. I could even see up to her navel and belly. Suddenly, she turned to the opposite side and I was completely lost by seeing my sister’s ass in a nightdress.

Her dress was stuck in her ass and I was staring at her ass unconsciously. After some time, she turned back and found me staring at her body. Our eyes met. As I regained my senses, I looked away from her body.

I went to my bathroom and masturbated thinking of my sister’s boobs and ass. Then it was normal for some days. I didn’t get a chance to see her cleavage.

After some days, my sister delivered a baby boy. In my family, all were very happy with the boy and we all believed that this indicated the birth of my grandfather who had died last year.

My sister was staying in our home for almost 10 months because she didn’t know how to handle the baby boy since it was her first time.

Daily after coming from the office, I used to play with my nephew (sister’s son). This was my daily routine before the meals. Then my sister used to take him for feeding milk. It was the practice in typical Indian family where the women feed their child with breastmilk for up to 1 ½ years. In that aspect, my family was very strict (my mother fed me for up to 2 years) so daily my sister used to feed him milk in the hall or in the bedroom.

After delivery, my sister used to wear a loose t-shirt so that it was easy to feed him. She used to lift her t-shirt above her boobs and breastfeed him.

Once I went to the bedroom to take my stuff. I opened the door and went inside the room. I was shocked to see my sister breastfeeding her son.

She was in this position where she had lifted her t-shirt above her boobs so that her boobs were clearly visible to me. Her right boob was being sucked by my nephew and the left boob was open. Maybe before I had gone there, her child may have been sucking her left boob.

I never thought that I would be able to see my sister’s boobs so openly. Immediately, she covered her boobs with a towel and she said,

Sister – Why did you come here?
Me – To take my stuff.

She – Don’t you ever knock on the door before entering?
Me- Sorry sister, I thought you were sleeping and did not want to disturb you. So I didn’t knock on the door.

Sister – It’s okay to see me breastfeeding my baby but when I come from the bathroom after bathing, maybe I will be without my dress. How it will be then?

I was shocked to hear that she was saying that it was okay to see her breastfeeding i.e. her boobs and also was talking about being without a dress.

Me – I’m sorry sister, next time it will not happen.
She – It’s okay, take your stuff.

I took my stuff and left the room.

One day I was playing with the child in the hall and simultaneously watching TV. After some time, the child started to cry. I called my sister and told her that the child is crying. She picked up her son and said,

Sister – Maybe my son needs milk. Nowadays my son drinks too much milk just like my elder brother.

I was shocked to hear this from her and I immediately said, “I didn’t drink too much milk.”

She – Then what you did when you were a child seeing the boobs of our mother?

I was shocked to hear her talking so openly about boobs. Meanwhile, our mother came to the hall on hearing the child crying.

Mother – My grandson is the same as my son. My son used to cry a lot and wanted to drink more milk and that is why I fed him for more than 2 years.

My sister winked and smiled at me. Mother told my sister to feed him or he will not stop crying,

Sister- Okay, mother.

Then sister sat in the hall on the bed to feed her child. She was in a loose t-shirt and night pants. I was shocked that she is feeding her child in front of me while I was watching some movie on TV.

Randomly I was checking to see what my sister was doing while I was watching TV. She was feeding her right side boob to the child by lifting the t-shirt above her boobs.

I was sitting on the sofa, the TV was on my right side, sister was sitting opposite me and facing toward the TV side. I could clearly see her right side boob. I was staring at her boobs while watching the TV.

One boob was outside and half of the other boob was covered with the child and that was clearly visible to me instantly. I was getting horny on seeing that nice view. When she looked at me, I was watching the TV acting like a nice boy.

Like this staring at her boob, I was enjoying the view of my sweet sister. After that, maybe the child completed drinking milk from the right side boob, so she changed her son’s position to the left side boob.

When she started to lift the right side which was covered earlier with her son, it was now open that showed 90 percent of her boob to me. I never expect that move from her.

Seeing her boob, I was getting more excited and the tent was forming in my underwear. I become so horny that I can’t control it and went to the bathroom and masturbated thinking of her boobs. That day, I cummed a lot more sperm than normal days.

My sister now was comfortable with me breastfeeding her son in front of me and a few days went like this.

One day in the evening, our daddy’s colleague from the office came to our home to see my sister and son.

Daddy was not there at home. I welcomed my uncle to our home and we were sitting in the hall and casually talking about my job and salary. His age will be around 30 to 35 years.

He asked me about my sister and her son. Meanwhile, my sister came to the hall and was sitting beside me on the sofa wearing a t-shirt. Uncle was sitting opposite us.

Uncle – How are you?
Sister – Good, Uncle.

Uncle – How is the baby? Where is he?
Sister – He is a good, uncle. He is sleeping in the bedroom and just had his milk.

Uncle was casually talking about his family issues and blah blah blah etc. While talking with my sister, he started staring at her boobs. At first, I was angry with him that he was looking at my sister’s boobs. I thought that why he was starting at her breast?

Then I looked at my sister and her breast. I can see that her t-shirt has a wet spot in the center of her boobs, near the nipple.

I can clearly see her nipple poking out from the wet spot. I became hot in my body. Maybe the wet spot was because she had breastfed her son 15 minutes earlier. The milk had oozed out of her boobs and created a wet spot near the nipple.

Then I thought, who will not stare at my sister’s boobs after seeing such a beautiful view of her boobs and nipple and the wet spot on her t-shirt?

After daddy came back and uncle had left, I told my sister,

Me – Sister, please wear a towel when any guest comes to our home.

Sister – Why?
Me – Uncle was looking.

Sister – Uncle was looking at what?
Me – Uncle was looking at your boobs which were clearly visible in your t-shirt.

This was the first time that I was talking about her boobs openly with her.

Sister- My.. (Then she suddenly saw her breast over the t-shirt and identified that her nipple was clearly visible).

Sister- Ooh. Maybe this is due to the excess milk in my boobs that my son didn’t drink completely. It shows a wet shop on my t-shirt near the nipple.

I was struck by her words. She was saying the word nipple in front of her brother.

Me- Yeah, sister. So please wear something when guests come.

Then I went to the bathroom and masturbated thinking of her boobs. She said, “Okay,” and went to the kitchen (she had a naughty smile on her face).

This went on for 2 or 3 times that she didn’t wear a towel. Finally, one day in the morning when our parents went to a relation’s function, my sister was as usual in a t-shirt. She was feeding her son on the bed in the hall and watching TV. I was on the opposite side on the sofa watching TV. I took courage and asked her,

Me – Sister, why don’t you cover your breast with anything while feeding?
Sister – Who told you that I am not covering with anything?

Me – Why should another person tell you? I was seeing that.
Sister – What? You are seeing that towel is there or not, or are you looking at my boobs.

I was shocked by her words. She was telling me about looking at her at the time of breastfeeding. I can see the smile on the corner of her face.

Sister – When did you see again? I was very sure that I am using a towel on the t-shirt when anybody comes.
Me – When our cousin Rajesh came home for dinner last week.

Sister- Oh, on that day I was wearing sari na..

Me – Yes, but when you were arranging the bowls for dinner in the hall, you were in a pink sari and white-colored blouse and without a bra. Once your pallu fell down in front of him, and your bare breast was visible to him. Your cousin was watching you.

After that every time you bent, your boobs were sagging down a lot and that showed him more of your bare, big, boobs.

Sister – Ooh shit. On that day I wore my mother’s blouse to get a loose fit so that it was easy to feed my son.
Me – That show was like a cinema with our cousin.

Sister – Sorry brother, next time I will concentrate on that.

Meanwhile, she was shifting her son to another boob while feeding him.

Sister – But I think you were right beside him (cousin). That means you also saw me like that.
Me- Sorry sister. (I was keeping my head down).

Suddenly, she was telling her son, “See son, my elder brother is seeing his own sister’s boobs” and she started laughing loudly.

She didn’t get angry and was in the spirit of laughing. I took courage and said, “Who can resist seeing your beautiful big boobs in an open saree blouse?”

Sister – So you also were looking at the cinema.

Me- Hhmm.

Sister- Tell me one thing, you told me that my boobs are big. Are my boobs so big that they look ugly?
Me – Your boobs are big but they do not look ugly. They have a nice shape.

Sister – It means that you’re observing me for a long time.
Me – No sister.

Sister – Then..?
Me – After marriage, you came home and I saw that you changed a lot. After marriage, your body has become physically beautiful.

Meanwhile, I was staring at her boobs and that wet spot near her nipples.

Sister – So my brother has grown up.

Suddenly, she asked me what I was looking at? I kept my head down.

Sister- Then I am correct. When you were a child, you didn’t cry for milk to see the boobs of your mother.

Me – At that age, what do I know about that sister?

Sister – So now you know that after seeing your sister’s boobs.

Me – Sister, that was an accident.

Sister – I know what is ‘accident’ and when you are staring at my boobs. I should be careful with you and my son.

Me – What did your son do?

Sister – Nowadays, he is also drinking so much of my milk and sucking my boobs more, just like you did when you were a child. Mother told me that when you’re a child you used to drink more milk and suck her nipple a lot. After that milk got over in her boobs but you were crying a lot for milk and that’s why she breastfed you for more than 18 months.

I was in shock hearing these words from my sister. I got angry went to her and said, “Give my nephew to me otherwise, he will also become like me.”

I was trying to take my nephew away from her, while she was breastfeeding him. My nephew was sucking on her left boob.

I kept my palm below my nephew on both sides of his head and legs to take him from her. In that process, my right side palm was under her son’s head touching her directly on her left side boob.

I had kept my left side palm under my nephew’s legs which were touching her right side boobs over the t-shirt. Her boobs were so soft which were silky white, and full of milk.

Her nipples were thick brown and she has big areolas. My fingers were touching her nipple while lifting her son. In a fraction of seconds, my mood changed from anger to horny state and there was a smile on my face.

What the fuck! What had I done? I thought that my brother-in-law enjoyed my sister a lot in bed with her boobs playing with them all night time. Instead, I got horny in the process.

Her son was in my hands and he started crying.

Suddenly my sister’s eyes became big.

Sister – You idiot, you are taking my son away from me.

She took her child from me.

Me – Sorry, sister.

She went to the bedroom. I went to my parent’s bathroom and masturbated. Thinking of my sister’s boobs that day, I came so much and I shot my cum on the walls of the bathroom. This had never happened before.
