Read the erotic story. My older brother took my virginity by having sex with me for the first time.
During my second year of vocational college, I had an internship semester. Luckily, my older brother was a branch manager at a company, so I got to intern at his company. He's several years older than me; he's 36, married, and has a child with his wife. My niece is a 15-year-old girl who's very pretty. So, I got to stay at his house in Bangkok (my house is a little outside of Bangkok) and help out with the housework for my very sexy sister-in-law. In the mornings, my brother, Oak, would drive his sister-in-law and niece (Ing) to work, and then he would be the last to go to work himself. I would also ride with him to work. The office was in a building in the Sathorn area. There were about 10 employees. I was Oak's assistant secretary, typing documents or answering the phone when he was on a busy call with clients.
I noticed that Mam (the secretary), Oak's wife, didn't seem very happy about me interning there, but she couldn't deny that I was the sister of the president/manager. Oak usually sat alone in his office. Mam and Nuna had a small room they shared, partitioned off next to it. In the afternoons, after lunch, Nuna noticed that Mam would spend an hour every day in Oak's room. Nuna became suspicious. One day, at 1 PM, Mam was in Oak's room for an unusually long time. Then someone called, asking to speak to Oak. Nuna transferred the call to the room, but it was busy, and the person insisted on talking to Oak. Nuna, annoyed, opened the door to Oak's room, intending to tell her brother.
The sight that greeted Nuna was shocking. Mam was lying on the table, her skirt pulled up to her waist. Oak was holding Mam's legs, spreading them apart, while his underwear was halfway down, between Mam's legs. Both of them were very shocked and quickly separated. Nuna caught a glimpse of Oak's large, hard penis. He slid his penis out of Mam's vagina with a loud "pop," his head twitching and shaking, wet and slippery with white mucus. Mam's labia contracted, squirting fluid out of her vagina. The floor was wet and messy from both of them. Mam grabbed her tiny panties, lifted her leg to put them on, and covered her skirt with her hand, while Oak stood there, putting his own penis back in his underwear.
The brother then continued to scold his sister, saying he was angry. Nuna felt ashamed and stood there crying, tears streaming down her face, "Hmph, hmph, I didn't mean to."
Oak told Mam to leave the room first, then came back and sat in the chair, offering Nuna another chair to sit in. We were both silent. Oak told Nuna...
“It’s normal for men. If a woman is tempting them, they can’t resist. I’m sorry, Nuna. You won’t tell anyone, will you?”
“I’ll go home now, P’ Oak.”
Nuna promised and walked out. Not seeing P’ Mam, Nuna packed her bag, went to the elevator, pressed the button for the G floor, and stood waiting by the sidewalk. She hailed a taxi with her left hand because she didn’t know how to use the BTS. She thought about what had just happened, seeing her brother and sister-in-law having sex in the room, the slippery white fluid flowing out in a foamy stream.
Since Nuna was born, held and nurtured by two hands as a baby, she had never seen the real thing. She had only seen it on porn videos, sitting with her legs spread and masturbating. Her female friends told her that:
“After having sex with their boyfriends, they got pregnant and gave birth to children.”
Nuna was a pure girl, with fair skin and a beautiful figure. No man had ever courted her. Therefore, no one’s penis had ever penetrated her vagina, only a roll-on bottle or a small finger. This is from me, Noonah.
Noonah was thinking a lot, picturing that scene. She wished it could happen to her. As soon as she got home, she got out of the taxi, rushed upstairs, opened the door, and went inside. She used her fingers to unhook and unzip her skirt, pulled down her underwear, and grabbed a bottle of antiperspirant.
Noonah then sat with her legs spread, inserting herself into her vagina. She opened her mouth and moaned loudly, "Ah…ah…ah…ah…ah…ah…oh ... There were tons of gadgets, including vibrating eggs, dildos, and pornographic books. Each book was full of pictures of naked women being fucked by men in various positions. So, I opened one to read. It turned out the pornographic pictures were of Oak and his sister-in-law having sex. There were pictures of them standing, lying down, sitting, and side-lying. They were both nude and very explicit. My pussy twitched and squirted, getting wet. My tiny panties again!
I was quiet and didn't speak to Oak that morning. After dropping off my sister-in-law and niece, Oak and I were alone in the car. I sat quietly. Oak asked me...
"Are you still thinking about yesterday?"
Noona felt embarrassed and didn't answer. Oak continued, "Don't tell anyone about this. When the time comes, you'll understand that this kind of thing is normal."
Noona then said,
"But don't you love Wan, Oak? Why would you do this?"
Oak replied,
"Of course I do. But you have to differentiate between sex and love. Sex is normal for people of reproductive age. Actually, you probably already have a boyfriend."
Noona countered, "No."
"Oh really? I thought you had a boyfriend. At your age,
who would want a girl with your looks and figure?"
"That's not true. My sister is beautiful and charming, with fair skin and a good figure."
Noona blushed and replied,
"If I had a boyfriend and had sex with him, wouldn't you mind, Oak?"
"I have no right to judge you, and you have to know how to protect yourself. There are many STDs. I'm serious, have you ever had sex with anyone?"
Noona blushed and replied,
"Never."
Oak said, "With such a capable sister, how about I find a man for you?"
"No, I'm a woman. No, brother."
"It's time for my sister to get pregnant." "I want to have children of my own."
We started talking more openly, without embarrassment, all the way to the office.
"Mam isn't coming to work today, probably feeling shy. Oak wants me to fill in for her. Please take care of her."
In the afternoon, Oak called me into his office to look at the computer. I sat down and noticed there were tons of pictures of naked women.
"You're getting aroused, aren't you? Have you ever seen these pictures before?"
"Yes, I have."
"And have you ever read about them?"
Oak opened the Swingstory website and showed me a story about siblings having sex. After reading for a while, I became sexually aroused.
"Do you want to see the real thing?"
I hesitated, feeling nervous and silent. Oak stood up at the edge of the desk opposite me and took my hand, guiding it to stroke his penis through his pants. I blushed, feeling embarrassed. Part of me didn't want to, but another part was curious. When I touched it, I grabbed it with my fingers.
"Take off my pants, little one."
I immediately obeyed. I saw Oak's penis hard, large, and long, pointing at me. My heart almost burst. I gently stroked it with my fingers, while Oak extended his right arm and stroked my pubic mound. Under Nuna's school skirt, her vagina was wet with her own fluids. Oak inserted two fingers into her panties, spreading her labia apart, and teasing her pink clitoris. She clenched her muscles, squirting out a copious amount of fluid. Nuna closed her eyes and moaned, "Ah, ah, ah, ah, ah, it feels so good, brother! Oh, oh, oh!"
You want to take over from Sister Mam, don't you?
Nuna remained silent.
P'Oak carried Noona up and put her on the table. Lift up your skirt. Pull up Noona's tiny panties. From between the legs, falling from the toes I saw a little black hair. Covering the bulging pussy mound The pussy lips close the hole close to the anus. Noona closed her eyes and felt that P'Oak's tongue licked Noona's pink vaginal hole. Her pussy clenched and squirted water between her legs.
หนูนาร้องคราง อ๊ะๆๆๆๆ ซี๊ดๆ อูยๆๆๆ ทนไม่ไหว น้ำของหนูไหลออกแล้วพี่โอ๊ค อ้อๆๆๆๆ เสียวจนไม่รู้จักผิดชอบชั่วดี Thrilling pleasure in the pussy Makes Noona forget all about brotherhood and sisterhood. Brother Oak is going to fuck Noona. Are you ready?
Noona nodded.
The tip of Oak's cock was inserted into Noona's pussy. Spreading and pushing the petals of her pussy open. It's not difficult to slide the long, hard cock into the pussy hole. The head of the cock hit the uterus, causing it to tingle because of the white, slippery mucus. A lot of Noona's stuff was flowing out of her pussy hole. Oh, big, long, tight. I felt pain in my pussy for the first time.
Noona is very excited. Look at Oak's cock. Swipe in and out of your own pussy. Wet, wet, slippery white slime, flowing, making loud noises. Noona didn't hear the word fuck from her own brother. But P'Oak's water came rushing in. Mixed with the water of many field mice. A bunch of eggs hit between her legs with a loud bang. P'Oak opened his mouth and moaned, oh, oh, oh, oh, oh, oh, so comfortable.
Because of the thrill Noona didn't hear those words. I could only moan, ahhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh
Noona was in pain and couldn't hold it in. It's extremely thrilling. She squeezed her pussy hole and squirted out water. Oiling onto Oak's wet cock, our juices mixed together and overflowed from the greasy pussy hole to the butt hole.
Noona finished it once. P'Oak still didn't stop pounding, using both hands to turn Noona's body over onto her face, putting both legs on the edge of the table, and P'Oak's cock plugged into Noona's pussy hole. Go into the back again.
Phi Oak swipes in and out. The head of the cock squirts semen into the ovaries and uterus. Until Noona was almost finished again, ahhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh... I'm almost finished. My water is about to run out.
Noona finished with P'Oak. Spray a lot of water and mix together. Juice from the head of Brother Oak's cock. It squirted all the way into my ovaries and uterus. Ooh ooh ooh ooh ooh ooh ooh ooh ooh ooh ooh ooh ooh ooh
Noona stood with her back, legs spread, on the edge of the table. Oak's cock slid out long. Wet, wet, slimy white slime. It was oozing and flowing out of her pussy hole. It's all over the legs of a field mouse.
Noona is the happiest. Never been like this before Enduring pain for the first time After being slammed for a long time, it felt good. P'Oak took a tissue and wiped the water in her pussy hole. With the fork of a mouse's leg Then he hugged Noona, caressed her two big breasts, kissed her mouth, sucked her tongue, kissed, kissed, kissed.
Noona is happy. Brother Oak gave birth control pills to Nanna to take.
Noona walked out and sat in front of a room. Brother Oak walked out. It's like nothing happened.
“It's better to go home, Noona,” and then went to tell the other employees that
I'll take my sister to the doctor. She's not feeling well.
The two of us walked out of the office. As soon as I got into the car, Noona's hands reached out to hug P'Oak.
“Nuna loves P'Oak the most in the world.”
P'Oak smiled and said
“When we get home, I’ll have sex with you until you get pregnant and we have a child together.”
Brother Oak, my body is ready to have a child.
After arriving home, we two siblings stripped completely naked, changed positions from standing to sitting to lying down, and had sex both front and back, even turning to the side. Brother Oak’s semen flowed profusely, mixing with my fluids. The head of his penis ejaculated semen into my ovaries and uterus, making a loud splashing sound.
Brother Oak’s penis was hard, big, and long, thrusting into my vagina. I groaned, “Oh, oh ... He held it in for a long time, his penis twitching and jerking, ejaculating semen into her ovaries and uterus while he kissed and sucked her tongue, making slurping sounds. He used both hands to caress her two large breasts, his fingers squeezing and gently slapping her buttocks. Noonah, Oak's wife, lay naked on the bed, having unprotected sex, ejaculating multiple times.
Oak pressed himself between Noonah's legs, preventing her from closing them. Her vagina overflowed, her wet and slippery penis sliding in and out, his testicles hitting her buttocks with a loud "slap, slap, slap." Their fluids mixed together, and they finished another round, both breathing heavily, exhausted. Noonah clenched her vagina, tightening around Oak's penis, her body trembling and convulsing, unable to close her legs. It was Noonah's first time experiencing the real thing. Her brother's penis thrust rapidly, ejaculating semen fully into her, mixing with the fluids in her ovaries and uterus with a "splish, splish, splish" sound.
Noonah was deflowered by Oak. Blood seeped from her vagina, flowing in rhythm with the thrusting of his penis. She moaned, feeling a mix of pain and pleasure. "Ah! Ah! Ah! Ah! Ah! Sss! Ooh! Ooh!" Her two large, white, firm breasts bounced up and down. Noonah became Oak's wife after Mam. Her brother's penis was hard, large, and long, thrusting against her labia, spreading them wide open. Slippery, cloudy white fluid oozed from her vagina and even reached her anus.
After that, Noonah got pregnant with Oak's child, and they had a child together. Mam also got pregnant and had a child, without her knowing that her brother had taken her sister as another wife.
"Oak loves Noonah and wants another child. What do you say?"
"And what if Mam finds out that Noonah is pregnant with Oak's child?"
"Keep it a secret between the two of us. Don't tell Mam."
"Okay, brother. Your sister is ready to have another child. Let's do it."
Oak used both hands to spread Noonah's legs apart. His penis thrust into her uterus, ejaculating a stream of semen inside. The large, long, hard penis was wet and slippery with white mucus inside the vagina. They both happily slid in and out, moaning loudly and breathing heavily, panting heavily, lying naked and exhausted.
Oak's semen mixed with Nuna's, making a splashing sound. Their bodies trembled and convulsed simultaneously. Oak had sex with Nuna at home from 8 PM until 7 AM, while Mam was also being fucked by Oak at work from 1 PM to 4 PM. The secretary position was held by only one sister-in-law, who didn't know that her younger sister was her brother's wife. Nuna had been promoted from secretary to vice president managing for Oak.
