Why do young couples make love so intensely?
A women's magazine that specializes in reporting on pornography wrote that, over a year, it happens about
once every night.
But my brother and sister-in-law! Almost every night, and whenever they get the chance, whether it's morning,
noon, or night, they don't miss a single one, just like eating three meals a day!
My sister-in-law, Chieko! She's a woman with a very high sex drive; the intensity she displays during sex
is startling. Although she's not my brother's type, she has a great figure, and
you can tell at a glance that she's the kind of woman who's very promiscuous and stamina-boosting in bed, so my brother is late every morning.
"It's okay, it's just a little bit late... Besides, this proves your love for me even more
!"
Sometimes I would quietly go to their dormitory and peek through the half-open door. Sometimes
I would see my brother tying his tie in front of the dressing table mirror, looking like he was busy getting ready for work, but his
pants were half off, and my sister-in-law, Chieko, was kneeling beside him, taking his penis out of his underwear
and rubbing it against her cheeks with both hands. This scene was truly shocking.
It was already past seven o'clock, which is the time for ordinary wage earners to leave for work
, and my sister-in-law's unreasonable insistence on keeping my brother there, along with her coquettish manner, left me completely stunned.
They were completely unaware that someone was watching them through the crack in the door, yet they were so bold…
Chieko held her brother's fully swollen penis, sometimes sucking on it, sometimes biting
and kissing it. Her excited, almost frightening, manner was almost maniacal, but the scene was so captivating
that I watched intently.
What would the brother do now? He watched his penis continue to swell, and his wife, Chieko,
relentlessly rubbed and even loudly gnawed at it.
At this moment, Chieko, her eyes filled with boundless lust, suddenly stood up and quickly removed her skirt and underwear,
even her pink shirt.
In the mirror on the dressing table, I saw Chieko's thick pubic hair, and her private parts seemed to be overflowing with
vaginal fluid. Just then, I saw my brother's hand reach out, so Chieko lifted one leg and rested it on the dressing table,
then bent over and raised her buttocks, striking a pose that said, "Come and fuck me."
Then I heard my brother say, "Like this, don't you think it's not enough? Just do it!"
"Yes! That's it... like this... hurry... hurry and give me your cock... hurry... hurry and
fuck me..."
"But Sanae's almost erect! What if..."
"It's okay! What are you afraid of... you won't be... hurry... darling... hurry... please...
fuck me..."
My brother, with his pants and underwear pulled down to his ankles, faced my sister-in-law Chieko, lifted her
large, white buttocks, and then thrust inside.
As my brother lifted Chieko's buttocks, I got a good look at her private parts. It turned out that her voluptuous
body also housed a large genital organ; beneath the thick pubic hair were two fleshy labia—a
truly breathtakingly large organ.
My brother's fierce thing was thrusting in and attacking! I saw Chieko using one hand to help insert it
, while her other hand pressed against the dressing table for support. Yes, my brother was fucking her from behind.
I watched Chieko's large breasts swaying violently in front of her, my god! The earth-shattering
moans of lust told me how intense they were going to be.
I couldn't watch any longer, so I quietly struggled and groped my way to the entrance, then went to work. Luckily,
I was only about half an hour late, though that lateness was also due to the passionate relationship between this couple.
Sometimes my brother would stay home to rest because of a cold, but that was definitely because he was too busy with Qian Jiangzi to
go to work.
Sometimes I think, my brother is really amazing at how he manages to handle Qian Jiangzi's constant courtship
!
In the year or so since they got married, although they've been immersed in passionate sex, they've also had their
periods of cold war. The reason for the cold war was that during my brother's annual company trip, he had a passionate night with either a hot spring geisha or
a female colleague, which made my sister-in-law extremely jealous, to the point of no return.
They had a cold war for about two weeks, probably because neither of them could bear the torment of not having sex! Finally,
they returned to their old life, and even more intensely than before!
From my observation, my sister-in-law, Qian Jiangzi, is a domineering person. She often orders my brother around, and despite this, my more
mature and steady brother usually tolerates her unreasonable demands.
I forget when it happened, but one night
, around 2 AM, I heard Qian Jiangzi making a lot of noise. I was almost asleep.
(What happened? So late!) What could be happening? As usual, I
listened intently.
I heard splashing water; the sound must be coming from the bathroom. This building has an automatic water supply, so we don't need
to heat water ourselves. But taking a shower at 2 AM is truly unacceptable.
I opened my eyes, got up, put on a coat, and walked out of my room towards the bathroom. I
could hear the couple's voices coming from inside.
There were two swaying figures; it seemed my brother was very drunk!
"...Understand? So we're not doing it tonight!"
It was as if they were arguing about something.
"So you mean you hate women's periods! So you're not sleeping with me tonight either!"
Chieko shouted in her high-pitched voice, the loud sound shaking the glass and shocking my
ears.
"That's not what I meant! I just... I thought since my period started, we should use
this time to rest properly. And if we can avoid taking a bath, a shower would be better."
"So you're a blockhead, an old-fashioned person too. That's outdated superstition! It doesn't affect you
doing me at all," the domineering Chieko retorted defiantly.
"I...I'm not interested..."
"Who's talking about interests with you! I'm talking about love. If you still can't understand, then
go sleep somewhere else tonight!"
"Hey! How can you be so unreasonable! Besides, we don't have any other rooms!"
"Hmph! Yes...isn't that your sister's room?"
"Hmph! You're..." "
It's not like siblings sleeping together is any big deal!" my sister-in-law said maliciously.
(Finally, the war is over. What an unreasonable woman!) I shook my head and immediately returned to my
room.
(Poor brother.) I thought to myself.
(Could my brother really be coming to sleep with me?) Thinking this, I fell asleep on the bed.
※
...

My brother and I are sleeping together—this is the first time since I was born!
Lying with my back to him, I slowly closed my eyes.
About twenty minutes later, just as I was falling asleep, suddenly, "smack!" A hand
slapped at me with a loud gasp, startling me. Of course, I knew it was my brother's hand…
He was fast asleep; perhaps he didn't know he was next to me…
His hand gripped me, and my heart started racing. There was nothing I could do; since he was already sleeping next to me, I
could only let him hold me. After all, he was my brother!
Then what happened? (So he did it on purpose!) I thought.
My brother slowly pulled my hand closer, breathing heavily, swallowing hard.
Oh! Then my hand felt a strange, warm sensation; it had touched a piece of flesh.
(Ah...this...what is this...?) Without even thinking, it's Chieko
's inseparable treasure...her brother's penis.
This warm thing, I'd peeked at it through the crack in the door before. The events of that day resurfaced
in my mind, and my body trembled involuntarily. Then, I instinctively gripped my brother's penis tightly.
(This cock that's always worried about not satisfying Chieko...sigh! Poor brother, he deliberately made me
hold his erect penis, could it be...?)
At this moment, my nipples started to itch, and I began to get excited...although this was a little inappropriate, I
didn't feel any objection to my brother doing this to me.
My brother grabbed my hand and started moving it. He made me rub his treasure. I grasped this thick
thing and slowly, gently, tenderly rubbed it with my five fingers.
My brother is repaying me! He slipped his hand inside my pajamas, his fingers
sliding under the edge of my underwear and into my genitals, gently caressing my vulva.
As his fingers were between my labia, I
thought to myself, "No! Brother, you can't do that..." but at the same time, I wriggled, trying to get my opening closer to his fingers so they could penetrate
deeper.
But perhaps in my haste, I pulled back slightly, causing his slender fingers to touch
my clitoris, and he began to tease it.
Unexpectedly, my body began to tremble; it felt so good. "Oh...there... harder... faster... brother..." I 　　was surprised
at myself for asking so clearly . 　　As my brother pushed his fingers further inside, I remembered his large, hot, and rock-hard 　　penis, the sensation of its penetration… 　　“Oh…what…Sanae, you’re already awake…” my brother asked, 　　feigning ignorance. I couldn’t detect his panic, so I boldly said, “Forget it! 　　I completely understand how you feel, brother! And today, let me take your place and make you feel good!” 　　These bold words slipped out without thinking. 　　Then I guided my brother’s hand to my thick, dark forest. 　　“Sanae, is it okay? Is it true?” my brother’s voice was filled with excitement. 　　Then his lips kissed my face, and he gently sucked on my ear. Oh! These actions really made my 　　whole body spasm with excitement. I pulled my brother's hand to my vulva and let him touch it; this was my response 　　. 　　As his fingers slid towards my slightly moist genitals, he inadvertently touched my clitoris, about the size of a bean. 　　The sensation of his touch sent waves of fluid through my uterus, causing more and more fluid to overflow. My pleasure 　　intensified. 　　As this fluid overflowed from my brother's fingers, he gently moved his hand. Then 　　he pinched my clitoris between two fingers and gently pulled it upwards, further stimulating my desire 　　. 　　"Oh…so good…brother…a little harder…" 　　The pleasure surged to my throat, my voice trembled, and my body felt like it was on fire; the 　　room felt like a greenhouse.

I was so excited I forgot the person next to me was my own brother; it was just a normal couple having
sex!
"Mmm...don't look at my face! Brother...please stop!"
"Okay! I didn't mean to..."
My brother's fingers moved like a spider, tracing paths across my private parts again and again. I
was already breathless with pleasure, my body trembling with intense ecstasy.
Was this a dream?
"Hey...brother...take a look, my clitoris is melting! Hurry...hurry! Help me check
!"
My words made my brother's heart flutter, and then he turned on the bedside lamp.
"Ugh...where's it melting? Let me check it carefully."
So I lay on my back, spreading my legs to let the light shine on my vulva. I don't know why I was so
bold as to ask my brother to do this; it was a rather complicated emotion.
"Your private parts are already swollen with excitement! And the color is very bright red. Also, this clump of pubic hair is quite
..."
He said this, inserting his fingers again, repeatedly pulling them out and then inserting them again,
playing with them up and down.
"Ah...that's amazing...really...brother..." I couldn't help but grab my brother's hand,
shouting like this.
A while later, my brother turned off the light.
"Sanae, just a little bit, can I insert it from the front? Or you can just leave it like this, I
won't force you." "I want to! Fuck me!" I nodded frantically, "But be gentle! This isn't 　　good
for Chieko !" 　　"Hmph! Don't mention that kind of woman!" 　　My brother said angrily, then he thrust his hard penis into my soft vagina with a "thud 　　." Then, with a "slap slap," he was thrusting in, and that alone was enough to make me ecstatic. 　　"Ah... I can't... I can't... It's so good!" Accompanied by this ecstatic cry, my hands 　　were also frantically groping and caressing my brother's waist. 　　"Hey...Sanae, I need to push it in a little deeper." 　　"Oh...okay...okay...faster, I can't take it anymore...faster...harder..." 　　My brother pressed his whole body against mine, thrusting rhythmically while kissing my lips, slowly using his 　　waist to penetrate me with each thrust. His thick glans pounded against my uterine wall again and again, 　　rubbing against my vaginal walls. The feeling was like falling into a cloud of mist, floating in blissful bliss. 　　With each thrust, hot, sticky vaginal fluid gushed out, quickly 　　wetting my pubic hair—a whole bunch! 　　With each thrust, my body electrified. 　　"Ah...ah...so good...so good..." I couldn't help but moan lasciviously, my hands 　　grabbing wildly. 　　"Oh...kiss me...fuck me..." 　　My brother pulled his penis out a little, leaving only the glans inside, then thrust it in again, repeating this motion 　　. When the glans touched the uterine wall, a strange sensation washed over me, making my mind race. Then 　　my vaginal opening tightened, gripping the glans tightly, matching its rhythm. 　　My body trembled as if electrocuted, matching the rhythm of the glans that was about to reach its peak. 　　My brother continued to use his hips, passionately thrusting in and out. 　　I felt the waiting was too long; I couldn't hold back any longer. 　　"Ah...no...I can't take it anymore..." I groaned, not even knowing what I was saying 　　. 　　My brother thrust in and out, twisting his waist as he rubbed my nipples with his hands, sometimes lightly, sometimes 　　heavily. His stimulation of my breasts fueled my rising desire, and my moans grew 　　louder. 　　"Ah...ah...harder...faster...oh...ah..." 　　I was startled by my own lewd moans. But these waves of lust only fueled 　　my brother's thrusting. 　　I realized my voice was too loud, so I put my fingers in my mouth to reduce the volume 　　. 　　My brother thrust as hard as I expected. 　　"Ah...ah..." Not only my moans, but even my rapid breathing seemed to ignite his passion. His 　　large, wet penis was fiercely plunging towards its apex. 　　To match my brother's rhythm, I arched my back to meet his, both of us striving for the penis to penetrate as deeply as possible. 　　"Ah...no...no...I'm coming..." 　　I felt my brother's hands press down hard, then he pulled out, and with a "whoosh," hot, thick semen shot onto 　　my stomach. 　　"Mmm...mmm..." my brother groaned. 　　Finally, we both reached orgasm. 　　After a while, my body stopped spasming and slowly calmed down, while my brother's rapid breathing 　　gradually evened out in my ears. 　　When I opened my eyes in the morning, my brother was gone. 　　That night, although I had sex with my brother, it seemed he and my sister-in-law, Chieko, had returned to 　　their 　　old life. Although I felt tricked, I could only 　　silently watch everything 　　unfold in their presence. Of course, I hoped their relationship would improve; after all, they were my brother and sister-in-law. And 　　I knew perfectly well that I couldn't let my brother sleep with me anymore. 　　Fortunately, after what happened that night, my brother seemed completely unaffected, still 　　treating me naturally, and Chieko didn't seem to have noticed anything about my relationship with him.

But about a month later, one late night, my brother came to my room again…
(Here we go again…) I thought.
“Brother, what’s wrong? No!”
I had just finished watching a midnight TV program and was changing into my pajamas, getting ready for bed.
I looked at him closely; he seemed to have drunk a lot and looked a little drunk.
“I lost track of time playing mahjong with my friends, and Chieko wouldn’t let me into the room.”
I couldn’t help but think: (This is going to happen again. Even though it’s not my fault, facing
someone so prone to hysteria… Sigh! Do I have no choice but to do what I did that night and sleep with him
?)
I thought to myself, and it was so late.
"This...brother...I think you should go back to your own room, it's more..."
Although I said this, the passionate
scene from that night flashed through my mind.
"It's okay! Nothing will happen. Chieko herself said you should sleep with Sanae! If we
change this double bed to a single bed later, you won't have this problem anymore!"
(What nonsense is my brother talking about? That thing that made me so intoxicated, he calls it a problem...) So they were just arguing about single versus double beds! I think my brother was planning 　　to come here
while they were arguing ! 　　But ever since I saw my brother coming here, I've really been tempted, and I can tell he's looking 　　forward to it too! 　　"Alright! Sanae, let me love you properly tonight!" My brother 　　whispered wickedly in my ear, his breath reeking of alcohol. 　　Ugh! This brother of mine always makes me lose control. 　　He had already torn open my bra and was licking my nipples with his tongue. A moment later, he gently 　　bit them with his teeth, and I cried out excitedly. 　　"Ah...ah..." A moan escaped my throat. 　　Naturally, I slowly opened my legs, but my brother didn't put his hands inside me 　　. He was only playing with my nipples. 　　"Oh...Sanae...you're such a cute little sister..." 　　"Ah...good...so comfortable...but my sister-in-law..." 　　My brother didn't answer me. He continued kissing my abdomen. 　　Starting from my nipples, then my breasts, then my abdomen and armpits, he licked my upper 　　body again and again, and of course, pleasure flowed through my entire body. 　　I raised my hands, letting him suck on my armpit hair. As soon as I raised my hands, my brother, as if 　　on cue, brought his lips close to my hairy armpits and kissed me passionately. 　　"Ah...so good..." I couldn't help but moan again. 　　I spread my legs more boldly, my waist beginning to writhe restlessly. In just a short while, I was already burning 　　with desire, hoping my brother would quickly insert his penis into my vagina and fuck me hard. 　　"Ah...brother...the front...the bottom...faster...fuck me...I...I can't take it anymore 　　..." I gasped, rubbing my brother's already erect penis with my hands. 　　Oh! This penis is burning hot! And it keeps dripping with sticky fluid, wetting my hands! 　　"Ah...ah..." 　　My brother brought his mouth close to kiss my lips again, and I couldn't help but moan through my nose, while I busily received 　　the saliva flowing from his mouth. Ah...this pleasurable moment. 　　"Hey! Is it okay?" 　　"Oh! Attack again." I urged him coquettishly. 　　As I spoke, I got up, and my brother slowly lay back. I hooked my legs around him and slowly climbed onto his body 　　, then straddled him like a horse. My 　　brother, lying face up, had his penis standing erect between his legs. I couldn't help but impulsively 　　grab this burning hot penis and shove it into my already wet vagina. Then I slowly 　　sat down, letting it fully penetrate my vagina. 　　Oh! The feeling was even better than last time! I arched my back, placed my hands on the bed, and leaned forward 　　, moving my body up and down, guiding the penis in and out of my vagina 　　. 　　I kept thrusting and panting, while my brother below kept kneading my 　　full breasts with both hands, occasionally pinching my nipples. My brother's thick penis was stimulating 　　the depths of my vagina, and combined with the excitement from stimulating my nipples, I was almost going crazy with pleasure. 　　Now I had complete control of the penis; with just a little effort, I could make it reach its peak, and the same amount of 　　vaginal fluid was constantly overflowing from my vagina containing the penis! 　　"Ah...ah..." I groaned, I had reached orgasm. 　　Of course, my brother had already ejaculated by then, and we hugged each other tightly, sleeping like that until 　　dawn. 　　My sister-in-law, Chieko, completely unaware of our affair, would sometimes send my brother to my room, 　　and each time we would have a passionate encounter. 　　The more we had sex, the more we wanted each other. I thought, if this continued, one day my brother 　　would definitely divorce my sister-in-law… 　　[The End]
