Hermanas: tangas y bombachas III

Note to users: this story is not of my authorship, it was written many years ago by another Poringa user called Nick Bendt, but since he's no longer on P! and his stories were deleted, I wanted to re-publish them so that this excellent history doesn't get lost. Enjoy it from now on. Note 2: all characters represented in this story ARE OVER THE AGE OF MAJORITYChapter VI: Everything has a priceMartín was attentive. His gaze rested on his sister's Booty. She, caught up in excitement, left her pencil on the folder and, lying face down, placed both hands on her hips, holding each side of the leggings elastic.

She looked at her little brother for the last time and began to take off her leggings. She pulled them slowly and quietly down. The first thing that appeared was the pink thong's edge. She continued to pull them down, and her well-developed buttocks became more exposed as she went. She stopped when she had pulled her leggings all the way down to the end of her Booty and the beginning of her thighs.

The boy watched it all. He was seeing his sister's Booty live and in person! The thong was too small, barely covering the crack of her ass, almost entirely exposed. It seemed extremely exciting... big, with volume, well-developed buttocks... the thong disappeared into all that flesh.

He had a hard-on pressing against his pants. He was so excited he didn't even bother to hide his erection anymore, not caring if Florcha saw it.

Florencia was also very turned on, occasionally glancing at her brother's bulge and sometimes wanting to see more, but she restrained herself.

- Well, that's enough-Did the girl say.

Martín just kept watching. She put her leggings back on this time, faster than before. She got them back in place.

- Ugh, a little bit longer??
- Ha ha no way, pervert! It's over for today.
They finished their study session, and Martín took advantage of what was left of the day to do his household chores... double-time. He had to mop almost the entire house. But nothing compared to having seen his sister in a thong. It was worth it, he told himself.

He also cooked lunch, leaving everything ready. Mom came home from work and thanked her son for cooking. Florencia sat down at the table too and called Agustina to wake up. a classic headache accused a major of having drunk too much the night before and stayed in bed. It was passing the day, and the boy was still very hot from what had happened that morning. He had his sister's naked booty on his mind, and his cock would stop every now and then. When his sister bathed at night, he thought about using her thong to masturbate. He called a friend who needed him for a game because they were missing a player. He accepted the proposal gladly and left. As expected, when he returned home in the evening, his sister Agustina was still in bed. He passed by the girls' bedroom and saw her awake, talking on WhatsApp. He went to the kitchen and found Florcha having tea. She was still wearing the same clothes from that morning. - Hello Flor, are you going to bathe now? - Hi, no, I have to go to Lucia's for a bit. Why? - Ahh... okay... nothing. - Eh? Tell me! - Well... because I'm about to take a bath... and I wanted... to do it. - Do what? - That! Masturbate... and I wanted to do it with your thong. - Ahhhhhhh. Shh, mom or Agu might hear us. It's so dirty. When I get back from Lucia's, I'll give you the thong, go take a bath. - Seriously? Thanks, sister! Martin gave his sister a cheek kiss and got into the bathtub. He barely took off his pants and boxers when his hard penis jumped out, eager for a good masturbation to relieve tensions... but he had to wait a bit longer. During his bath, he touched himself, jacked off thinking about his sister's booty with the pink thong, and when he was about to climax, he stopped. He got out of the bathtub and waited for Florcha. Meanwhile, he entertained himself on Facebook. Florcha finally arrived home. Martin was sitting in the living room with a notebook. The girl looked at him and asked where everyone else was. - Agustina is still in her room, and mom went out to buy food. - remembers, from...? - Yes, you're so rushed? - Well... a little yes je. - Aysssss, come with me to the bathroom and I'll give it to you. Florencia walked to her bedroom to make sure Agustina was there. Then she went to the bathroom with her brother behind her. The boy already felt his cock very hard and his heart racing at a thousand. Florcha opened the door and entered the bathroom. - Wait for me here... don't make any noise. –She told the boy behind the door, outside the bathroom. First, she took off her sneakers. Then she removed her legging, and finally she slid down her thong to her feet, to take it off and hold it in her hands. She opened the door slightly, just a little bit, stuck out her hand there to get it for her brother. - Here you go. - Thank you!!!! Martín grabbed the thong his sister was offering him and left while the girl started taking a bath. He went to his room, closed the door, turned on the light, sat down on the bed, and took off his pants. Now he could observe clearly the thong of his sister. It was super wet! She opened it all up and looked at what was always there, the inside part was very very wet, completely. The narrow part was very small, the boy thought for sure that that part had been all inside her pussy. He felt the smell and had to touch himself. He brought it to his face to feel the deep smell of pussy coming from that thong he had seen on his sister's ass in the morning. While with one hand he let the thong rest on his face to sniff it, with the other he jerked off. After a couple of jolts, he started cumming. It was intense. Semen fell and fell from his cock. He thought he had never come so much semen. He filled the floor of his room with sticky semen. Urgently, he opened the door and looked around to see if anyone was near. He went to the laundry and found the floor cloth he had used in the morning. He took it to his room and cleaned everything up in seconds. As fast as he could, he put the cloth in a bucket of water. and he took it to the patio.
Regressed to his room, what relief. Everything's fine. He grabbed the thong again and looked at it anew. Having seen her all in the Booty... it was getting hard again. Another occasion, he smelled it.
Now he had it hard again. He had to lower his pants again. He wanted another one. Why not?
Besides smelling it, he licked it, passed his tongue over the wet part. He loved the taste of his sister's snatch.
Then he wrapped the thong around the trunk of his cock standing up, and jerked off... this time the cum that came out wasn't as powerful. It didn't shoot out, but rather dripped from the glans downwards. It fell onto the trunk of his cock, staining the entire thong with semen.
Once finished, Martin had a penis full of semen. He unwrapped the garment and cleaned his cock with his sister's thong. He passed it over the entire cock and pubis, a bit over the testicles, to clean up all the cum.
The pink thong of Florcha was filled with warm cum. He put on his pants and left the room with the thong hidden in his hand.
He went to the bathroom. Opened the door and told his sister he had already used it, that she could leave it with all her clothes. She accepted.
He stayed in the living room watching TV.
When Florcha came out of the bathroom, she immediately looked for her brother. Found him sitting on the couch in front of the TV.
- You're a jerk, what's this?
- What thing?
Florcha showed her brother the thong full of cum, holding it by the fingertips.
- Is that what I think it is?
- Ahh... yes, I thought you might mind... didn't know if I should tell you.
- This thing is your semen, right?
- Yes...
- Are you stupid? Can't you be THAT GROSS. You ruined my thong!
- Why?
- How why???!!! If you left it full of semen, gross.
- But it can be washed, Flor.
- Si???!!?? And who's going to wash this filth? Look if Mom sees this?
- Ah... haha you're right.
- See? And you think I'm going to put it back on? esto after you've filled it with semen? Apart from Agustina, we share our panties, see if she finds out!!!!
- Relax, we wash them well and they come out like new.
- You fix everything easily. What did you do with this? I don't understand how you made me dirty like that.
- Well... first I smelled it... it had a rich smell, I gave myself a hand job...
- Again those words!
- Well, sorry... I was...
- No, leave it, tell me however you want... it's already too late.
- Well, I gave myself a hand job... and I got hot again, so I smelled it again and had to do another one.
- You jerked off twice???? - Florencia asks, surprised.
- Yes... because of this morning, when you showed me the booty, and then smelling your thong, I was super excited! Then when I did the second one, I finished and got all messy... and I cleaned up with your thong.
- How?!?! You used my thong on your dick?!
- Yes, relax, it washes off, sister...
- I can't believe it. And I'm almost touching your semen, take it and wash it yourself, you pig!
- Florencia gave her brother the thong.
- It's not that bad, it was tremendous, thanks for giving it to me, Flor.
- Yes, I see how tremendous it was, if you jerked off twice and filled it with semen.
- Haha, because I love the smell of your pussy.
- Bueeeenoooo! Don't get carried away!
- Sorry, but I'm trying to be sincere...
- Yes, I know, but you're disgusting. The next time you do this, don't give it to me, put it straight in the washing machine!
- Well.
- Ah, and my pussy has a horrible smell, I'm ashamed that you can smell it. Nothing more. And yes, I speak with those words, let's see if you understand, haha.
- Florcha laughed and went to her room.
- Martín went to the laundry to clean the thong. He put it in soak and removed the stuck semen. Then he put it straight into the washing machine.
- That same night, as they had agreed, Florencia and her friends went out with Martín. The guy didn't really like going out with all those women, but that's what was due, his friend didn't want it. They went to a nightclub, where some of Florcha's friends had drunk too much and let themselves be flirted with by the boys.

Florencia and Martín also drank, and the night was fun together. None of them approached Florencia, maybe they thought she was with her boyfriend... but it was her brother.

They asked for a taxi and went back home together, already dawn on Sunday.

They entered the house trying to make as little noise as possible. They were joking about a boy who was so drunk he couldn't stand up in the nightclub.

Florencia arrived at her room while Martín had to go down the hall to his own.

- Finally time to sleep. –Mentioned Florencia, yawning.

- Yes, I'm very tired.

- Do we study again this afternoon?

- Yes!!

- Ja, you want to study to see me.

- Also... although I like helping you.

- Jaja, yes, of course... let you rest.

- Similarly.

After the break and lunch, Martín was watching a soccer game when Florencia arrived at the living room asking if he wanted to study for a bit. Obviously, the boy turned off the TV and ran out with her.

The same scene repeated itself. She lying in bed, he sitting beside her, they studied. While studying, Martín looked at her Booty and as her underwear was visible just below the jeans.

- What are you looking at?

- You're already showing a little...

Florencia looked and laughed.

- Well, focus on studying now... later that.

- You've had your eye on me since last night, haven't you?

- Yes.

- Is it like yesterday's thong or a pair of underwear?

- It's a pair of underwear, pig, now study!

When they finally finished studying, Martín's pants were already getting tight. Florencia closed the folder.

- Come on, little sister, show me the underwear.

- Go see if anyone is nearby.

Said the girl.

Martín opened the door to the room but there was no one nearby.

He closed it again and sat beside She.
- Nobody.
- Ok.
Florcha unbuttoned her jeans and was about to take them off, but before Martín stopped her.
- Flor, I want you to show it to me from the front.
- From the front?
- Yes!
- Oookey.
The girl knelt on the bed in front of her brother, and lowered her jeans down to her thighs. In front of him, her pubis appeared covered by a white G-string. You could see that her pubic hair was slightly transparent.
- I've already seen it, I'll put my jeans back up.
- Just for a little while longer, Flor.
- Uh, come on, what else do you want to see?
After showing her brother the G-string for another couple of seconds, she finally put her jeans back up.
- Thanks, Flor, you're beautiful.
- Haha, go...
- When are you going to take a bath?
- In a little while, I'll be right there, will you use my G-string?
- Yes, I'm really looking forward to it.
- Well, but don't stain it with semen....
- Does it bother you that much? If they get washed, don't be so mean... I love smelling it and I like filling it up with cum a lot.
- Cum?
- That's what we call semen, little sister.
- Oh, come on...
- Then? Let me pour my cum all over it, please...
- Okay, but if you fill it up with cum, put it in the washing machine, don't leave it there, understood? If Agustina sees it, she'll kill us, and God knows what Mom will think.
- Yes, calm down.
Martín left the room. Florencia, just thinking about her brother was going to masturbate with her G-string, got excited. In the bathroom, she took off most of her clothes and rubbed the G-string well against her pubic area to make sure it was nice and wet and smelly for her little brother. She pulled it out and left it there with all her clothes.
After bathing, the boy entered the bathroom and grabbed the item. He opened it well and realized how soaked it was. The smell of pussy was incredible. He masturbated and finished on top of the G-string directly. He cleaned himself off with his sister's fabric and left it there. When he finished bathing, he went to the washing machine and put it in. washbasins. The girl when she went to sleep, recreated in her mind imagining herself as her younger brother making a masturbation smelling his underwear, and then imagined how it would be passed through the cock, filling it with hot and thick semen. She felt very excited against. At first it seemed disgusting to her, but now she loved it. She enjoyed giving her wet underwear to her little brother so he could make himself off and fill them with cum.

She had to masturbate in bed, thinking about that. Putting her hand inside the underwear, touching herself clitoris, and nipples. She decided to go further, and put the underwear in the crack of the use the word: pussy, to fill it even more with her flows and smell. She had an excellent orgasm. Just as she was going to sleep and already had the underwear soaked for tomorrow! She slept all wet.

Now that she knew what her brother did with his clothes, she was hotter than ever. Almost every day she was excited, and moistened the double underwear before they were. This noticed her brother, who each time he received them, they were much more humid than the first times.Chapter VII: Where is the line of limitation?Monday, Florencia thought about changing her underwear before school because it felt too wet from last night's orgasm, but she left it on to excite her brother more. She was excited all morning, despite having masturbated the night before. She needed to do it again, Florcha had the need to touch herself once more. Occasionally, while in the living room and making sure no one was looking, she would discreetly rub her fingers under her school skirt, lightly touching her pussy above the underwear.

After school, Florencia thanked Martin for helping her with her math homework that day, as it was all correct.

At mid-afternoon, while mom was still at work and Agustina was in university, Florencia left her math notes on the kitchen table for Martin, since she had more homework. Martin opened the notes while taking a coffee.

- Don't we study today? - Asked the boy.

- I don't really feel like it, apart from a little bit later when I have English.

- Ok. Although I'd like to see your underwear a bit.

- Jajaja. The deal was that you would see it when we studied!

- Yes, I know... but since we're not studying today... let me see it a bit.

- Jaaa, no, you're a trickster! Now I'm going to take a bath, and I'll leave it in the bathroom for you to jerk off later.

- Siii, thanks sister.

After getting into the bathtub, Florencia took off all her clothes except for her underwear. She opened the shower and started touching herself again before getting in.

She was standing in front of the bathtub, leaning against the wall. She was rubbing her clitoris in circles to give herself pleasure. More wet, more horny, more excited like a fox. She brought two fingers to her mouth to lick them, and then back to her clitoris to stimulate it. It didn't take long for her to reach climax. She ended up like a slut, leaving as much of a trace as possible on the underwear that was now almost completely...

Empapada directly. She had masturbated twice on top of that bra.

She dried all the cum from her use of the word: pussy with the bra and left it lying in the bathroom for her brother to find.

In a few days, she had turned into a slutty one.

Florencia came out of the bathroom already dressed, brushed her hair, and left for English, greeting her brother who was still doing his homework at the kitchen table.

Once the boy finished his homework, he went to the bathroom, picked up the wet bra from his sister, and did what was usual. He couldn't believe how soaked she left him, but he appreciated it. After feeling the smell of his sister's dirty pussy, he put the little bra on the tip of his cock to finish masturbating and fill her completely with hot cum.

Once done, he folded it all up and put it in the washing machine covered in semen.

A while later, his older sister Agustina came home from university. The first thing she did was go showering. What happened when Martín went to take a bath? He rummaged through Agustina's clothes, found her bra, and had another masturbation session.

This time it was a black bra, unlike Florencia's, which wasn't wet. It was all dry, but after smelling it in the vaginal area, he felt the unmistakable smell of use the word: pussy, although not as deep, but just as exciting.

He couldn't come on this bra, so he just masturbated while smelling it.

After all that, already very satisfied, he prepared to take a shower.

After dinner, Martín sat next to Florencia on the living room couch, while Agustina and his mother had already gone to sleep.

- I finished your homework, Flor. I left everything in your folder.
- Seriously??? Many thanks, brother!! Your reward is in the bathroom as promised.
- Yeah, thanks for leaving it for me, Flor, I swear I loved it!!
- That's good, then you had a good time.
- Very well!!! You left them very wet yesterday and today. They had a rich smell. I did a... masturabation with yours, and then I did another one with Agus's bra.

- With both of them?!?!
- Yes jeje.
- Do you also want to feel up Augustina's too?
- Yes.
- Hahaha, what a dirty guy. I'm going to sleep. See you tomorrow.
- See you tomorrow sister.

:::

It was dawn. When he was getting out of bed, Martín realized his head was splitting and he had a sore throat.

He told his mother he didn't feel well. Mom put her hand on his forehead to take his temperature and gave her diagnosis: You have a fever, dear. Stay in bed today and rest

The boy didn't say anything else and stayed in bed sleeping while his sisters were getting ready for university and school.

He slept until noon when he got up and prepared lunch for the three women of the house. He wasn't hungry, just going to take a hot soup, and went back to sleep.

For the afternoon, Florencia entered her brother's room and woke him up.

- Let's study for a bit? Or are you really sick?

- I'm sick but I can study, and more with you.

- Haha.

The boy accepted. Florencia told him to stay in bed and she sat down beside him. She opened the folder and Martín started explaining some math problems and solutions to her.

Florencia was wearing a low-cut tank top that invited people to peek at her tits, and her red and black checkered school skirt was crossed over her legs on her brother's bed. Martín looked at her, looked at her legs, and obviously wanted to see what was under that school skirt.

- And how do you solve this problem? - Asked the girl.
- Like this... you have to...(the boy's explanation)
- Ahhh it came out so well!!!! - Exclaimed Florencia.
- Good job.

Florencia looked at her brother and observed him looking at her legs so openly.

- You're sick but you still keep staring, haha.
- Haha, yes. Your legs are beautiful.
- Thanks.
- Estás enfermo pero me seguís mirando igual eh, jajaja.
- Jajaja, sí. Qué lindas piernas.
- Gracias. - Today's your turn for the deal, eh.
- Hehe, yeah brother, stay calm, I didn't forget.
- Do you have a thong or G-string today?
- Thong.
- Are you wearing a thong to school?
- Hehe, yes, no one sees me, don't get jealous.
- Hehe. Show me your sister's thong, pervert?
- Yes, pervert.
- Florencia spread her legs slightly, lifted her skirt, and sat on the bed, showing her brother the front of her thong. Martin saw the blue thong triangle covering his sister's pubis.
- Mmm, how beautiful, Flor. It's really turned on.
- To see the thong?
- Yes. Do you want me to get up and take off my skirt?
- Would you like to see me without a skirt?
- Yes, please. I want to see how the thong looks on your Booty.
- Florencia couldn't help but get wet from the thong. The situation overwhelmed her, she was very hot, with her pussy swollen from excitement. The more swollen, the tighter it sucked into the narrow thong fabric.
- She got up and lowered her skirt to her feet. She turned around, showing her brother her enormous butt tangled in the thong. Only the crack of her butt was covered.
- Uff, I love how you look with that thong, Flor... although I like your Booty even more... it's huge!
- Hehe, seriously, do you like my Booty?
- Yes, apart from the thong, it barely covers anything... are you going to give me a blow job?
- Yes, in a minute I'll go take a bath.
- Is it as wet as yesterday's G-string?
- ...Yes, it's a bit wet.
- What a good thing... I can't wait to smell your pussy sister.
- Will it have a good smell?
- Yes... I already told you it's rich, I'll cum soon.
- Will you fill me with your cum?
- Yes, I can't hold on anymore... I'm really hard, Flor.
- Do you want it now?
- Yes.
- Florencia put her skirt back up. She put her hands under and started to slide the thong down her thighs, without letting Martín see anything.
- She grabbed the wet thong and threw it at her brother. On the bed.
I'm going to take a bath. Have fun.
Thanks, Flor!!!
Florencia left her brother's room with her skirt on and nothing underneath, with her pussy burning. She barely entered the bathroom, sat down on the toilet, opened her legs as wide as she could, and masturbated like never before. She spat out two fingers and rubbed them all over her hairy pussy, trying to relieve the heat and tremendous excitement. She imagined how her brother would be smelling her thong right now, enjoying the smell of her pussy, and filling it with hot, yummy, and thick cum. She had a majestic orgasm, trying not to moan like a slut. She stayed trembling. She grabbed her pubic hair tightly and brought her fingers to her mouth. She had never felt her pussy so inflamed.
Her brother? As soon as Florencia left his room, he took off his pants and smelled the thong that had been in her pussy and booty just seconds before. He was so hot that he came right away. There was a lot of cum. He filled his cock and pubic area with semen. He cleaned himself up by passing the thong over his cock and balls, leaving it completely full of cum.
A while later, Florencia came out of her shower, wrapped in a towel, to look for the thong in her brother's room. He gave it to her.
Ah good. How many jerks did you give yourself? Haha.
Just one... but it came out a lot because you left me very hot, sister.
Haha, is that my fault? Well, there's no other remedy than to touch your semen.
Florencia grabbed what seemed to be her thong, full of her vaginal fluids and her brother's semen. She had to get her fingers dirty with cum. She went back to her room to get dressed. She left the thong on the floor, intending to take it to the washing machine later. She was getting dressed when she heard her mother arriving at home.
Florenciaaaaaaaa! - Her mom shouted from the living room.
What's up? - Florencia responded.
I need your help with something... - Her mom said. to see what her mother wanted. I had to help her with some shopping bags from the supermarket. While helping her mom with that, she saw Agustina passing by, who was arriving home and crossing directly into the living room. Florencia remembered the thong full of cum in her room.!!!!!!!!! Late. Florcha left one of the vegetable bags on the floor and looked down the hallway. She saw her sister enter her room. Oh no. And now? Her mom asked what was wrong, why she had been standing there frozen. She finished putting away things and went to her room. I didn't know if I should go in or not. Maybe she hadn't seen me, she thought. She was terrified and trembling!!!! It had been a while since she was trembling from orgasm, and now she was trembling with fear. Finally, she opened the door. She saw the worst. Agustina holding the thong, trying to figure out what kind of filth it was. Agus saw her enter and looked at her. Florencia entered and closed the door. Florencia... what is this? Florcha remained silent, feeling her eyes start to get wet, trembling, and beginning to cry like a baby. ...
