I have a foster sister named Wanjun who is very close to me. She is a few months younger than me and lives with me. A foster sister means she often plays with me.
Sometimes we would flirt with each other, but it was just the kind of relationship where we were sworn brothers and sisters. We lived in separate rooms under the same roof. Jun liked to chat online very much and would often play until after four in the morning before going to bed. For this reason, I often missed her!
One time, I needed to use the computer for something, so I went to her room to borrow it. She was not there, so I turned on the computer and found that there were many erotic articles stored in her computer. At that time, I really couldn't imagine that picking up girls was associated with these erotic articles. I remember when I first noticed Jun, she was 160cm tall, with very plump breasts of C cup, round buttocks, well-proportioned figure, fair skin, and long beautiful legs...
(It hurts my heart)

****HiddenMessage********

As I was thinking about it, my little brother hidden in my pants was already erected and feeling sad (it’s a pity that my sister was not around, so helpless) Okay! In order to stop myself from thinking too much, I quickly checked the information and returned to my room, but I couldn't fall asleep no matter how hard I tried. I thought of my step-sister's seductive body, her plump C-cup breasts, and her round butt.
I started to masturbate, and after masturbating, I felt much more comfortable, but my penis was still hard and hot, and my mind was still thinking about my sister (her plump figure).
I thought about how she would react when she read those articles. After a while, I felt the urge to pee, so I got up and went to the toilet...
When I walked to Jun's door, I found that her door was not closed. I wondered when she would come back, and the door was left a big gap. I was just imagining how sexy she looked.
Curiosity made me unable to control myself, and I walked towards the room... I wondered what Jun was doing now? Was my sister reading those articles? Or... I came to the door of her room and peeked through the crack of the door...
call! My sister was still playing on the computer. It was already midnight. The light from the computer screen shone on her body. She was wearing nothing under her transparent black suspender nightgown. Her plump C-cup breasts and her cute little nipples were vaguely visible. Unfortunately, it was too far away and I couldn’t see what color they were. It was the first time I saw my sister wearing something so sexy. Usually, no matter how she looked in front of me, she would always wear a bra and panties under her transparent suspender nightgown. But now she was wearing nothing at all. I was really afraid that I would not be able to resist going in and raping my beloved sister, so I quickly ran to the bathroom and took a cold shower, hoping to cool down my hard and hot little brother and eliminate the lust…
I went back to my room and lay on the bed. It was already past three o'clock. I couldn't fall asleep after tossing and turning. Jun's sexy body kept appearing in my mind. I thought I should think of something else to distract myself. But the lingering image of Jun's sexy body and such plump C-cup breasts was really unbearable. I really wanted to rush to her right away and enjoy her...
Suddenly, an idea came to my mind: it would be fun to secretly look at Jun while masturbating. With this thought in mind, I slowly walked to Jun's room and peeked through the crack of the door. I saw that my sister was holding the mouse in her right hand and touching herself with her left hand. From time to time, I could hear Jun's mouth humming softly (Ah... Ah... Ah!) Oh oh!
Jun is masturbating? DIY? I can't believe my eyes, wow! It's a really pleasing picture, but the fact is right in front of me and I have to believe it. I see her masturbating deeply, stroking her own cunt, and moaning softly in the room (only a girl can moan in oblivion). I'm stroking my little cock outside the door, and she straddles her left leg on the computer desk. From my angle, I can vaguely see her hands touching and pumping near her cunt, and her hips twisting from time to time to match the movements of her hands.
I didn’t expect my step-sister to have such a slutty side. Her slutty and plump buttocks twisted sluttishly, her C-cup breasts swelled up and down due to her breathing, and her nipples stood up hard. I kept stroking my hard and hot little cock, and paid attention to the movements of my hands. Her hands should be (rubbing) (thrusting) (stroking) the entrance of her cunt!!! I guess she is very wet now?! She should want to have a…

Suddenly I heard "Ah...Ah...Ah..." and started to moan!
She inserted her fingers into her wet hole, then paused and continued reading her article!

"Yeah... Yeah..."
Her fingers began to thrust in and out of her wet hole. I wished that it was not her fingers but my big brother that was in her wet hole.
"Yeah..."
Her fingers were pumping in and out of her wet hole, and her butt was twisting lasciviously... Ah... Ah... Ah!!!

Yes...Brother...fuck me! Fuck me~! Oh...Ah...Ah...Ah...I was shocked at that time. It turned out that she was still intoxicated. I thought she had discovered me and was just fantasizing about being fucked by me...!

kindness……!
She seemed to have finished reading the article, put down the mouse, and joined in with her right hand, caressing her C-cup breasts!
She pinches, touches and kneads her plump C-cup tits!

I was so tempted to see my sister performing a provocative and lascivious act for me.
"Yeah...ah!"
Her fingers moved faster and her body trembled slightly!
I feel like she's about to reach her climax! Ah...ah...ah!

I couldn't bear it any longer and gently pushed the door open. My sister noticed it and was surprised at first, then she turned her face away, not daring to look at me. I walked over and carried her to the bed. I couldn't resist the desire and began to kiss and lick her. She closed her eyes, blushed, and responded fiercely. My sister's tongue was entangled with mine, and her hand was still pumping in and out of her pussy.
She kept humming in her throat, wanting to scream, but her mouth was blocked by me so she couldn't scream. I held her with one hand, and with the other hand I caressed and pinched her C-cup breasts. My fingers gently moved on her C-cup breasts and gently pinched her nipples. My mouth moved to her neck, biting her neck and licking her ears. She couldn't help but scream out (Brother...ah...ah...so...so comfortable)!
Hearing Jun's cry, I seemed to be greatly encouraged. I moved my mouth to her C-cup breasts, and licked her nipples while she was wearing a transparent nightgown with suspenders. I licked her nipples with my tongue, and then I put my arms around her waist and pulled my hands out. I grabbed her C-cup breasts with both hands, and kept licking her nipples while switching between left and right.
"Ah... ah... ah... ah... Jun's moans have become more and more lewd, and her lewd moans have been stimulating my desire! I can't bear it! I reached down and took out her hand that was inserted in her wet hole, put it in my mouth, and licked her transparent lewd fluid, which tasted salty! I put my mouth in front of her wet hole, and she suddenly blocked it with her hand: ah ah... brother... don't,
It's dirty in there!
Sister! Don't be afraid, as long as it's on you, I don't think it's dirty. To me, this place is the most beautiful and cleanest! I said firmly!
I opened her hands, put my mouth on her, and began to lick her wet hole. She couldn't help but scream: Ah... so comfortable... Brother... I can't stand it... so comfortable, so good...
I put my tongue into her wet hole again, stirring it back and forth and licking it, licking it inside her wet hole! Licking! Licking! Sucking that little bean...smelling the alluring smell coming from that wet hole...
The juice kept flowing out.. The more she moved, the more she felt her need.. She sucked up all the sweet juice.. Like finding a precious source of water in the desert.. She buried her head in the mouth of her vagina..
And the lustful juice keeps flowing out..
..
Ah...ah...brother!...ah...oh...so good...so itchy!...brother!...your tongue is so powerful!I can't stand your licking~it feels so good when I lick you.I put my nose against her wet hole, her little bean has already become hard, I sucked hard the love juice flowing out of her!Ah...I can't stand it anymore!...I...I want to orgasm...
. Alright…Her buttocks catered to the movement of my tongue, her hands held my head, and the love juice in her wet hole kept gushing out! Ah…ah…ah…ah…ah…ah…
…Brother…Brother~! I…I…you…made me…feel so good…ah…suddenly, her body trembled, and a lot of love juice gushed out of her wet hole, and I drank it!

Jun was panting, I hugged her, the orgasm made her body more sensitive, I put my big brother on the outside of her wet hole and rubbed it, her body trembled, she hugged my neck, and hummed in my ear: Brother... don't... don't tease me anymore... so... so comfortable... so sensitive!... ah... how could I let her go! I rubbed her wet hole up and down with my glans, and my big brother rubbed her sensitive clitoris from time to time. Jun couldn't stand it anymore, and turned over and pressed me down!

Jun: I can't stand it! She pressed on me, held my cock, touched it and aimed it at her wet hole, sat down, and couldn't help but humming ~ Ah. Brother.. Ah.. It feels so good~!

I immediately felt that the wet hole was tightly clamped around my glans, and the rest of the part had not been inserted yet ~ It felt so good but I felt that her wet hole could not bear it anymore, so I immediately supported her, and she slowly moved! Well... well... ah... I can't stand it... It feels so good... ah... well... ah~ Suddenly! My glans slipped out, probably because it couldn't be inserted too deep, so my sister anxiously supported my big brother, slowly sat down and inserted it ~ Ah... This time it was deeper, the penis was half in, I could feel very excited, the wet hole was trembling, she began to move slowly again, and she kept shouting.

Well…I hate it!…I…I gave you my first time…my first time…ah…you still say such things…well…I saw that she was willing to answer my questions, so I asked: Then what did you use to break your hymen? She suddenly raised her hand and hit me in the chest: Bad guy, bad brother!…I broke it myself when I masturbated…ah…brother!…
I…I can’t do it anymore! I’m so…so tired! Her movements started to slow down…
: : : : : : : : : : : : : : :
I knew she was about to orgasm, so I thrusted in and out of her as fast as I could, each time reaching the deepest part of her wet hole and touching the opening of her uterus. Half a minute later, she suddenly tightened her legs around my waist, and a stream of love juice spurted out of her wet hole! She screamed "Ah...", and I knew she was about to orgasm, so I thrust my penis deep into her wet hole, and held it there, feeling the trembling inside her wet hole and the contraction of the wet hole walls!
Feeling her climax, I moved my mouth closer, my tongue went deep into her mouth, stirring with her tongue. She seemed to have no strength to respond, and my tongue just gently pushed forward, letting my tongue actively entangle with hers (I sucked her tongue crazily). I looked at her tightly closed eyes, hugged her trembling body, she was panting, and it took her five minutes for her breathing to calm down!

Sister! Are you done resting? If you are, I will continue! I asked! Well... She responded to me with her eyes closed!

I started thrusting again, pulling out from that tight wet hole, and when I thrusted in again, I could feel the wet hole filled with her juices being squeezed out of it because of the entry of my penis, and a sound was heard.
"Puff, puff"
The sound!
Maybe because she was so sensitive after the orgasm, she started to moan as soon as the big brother started to move: Ah... Brother... You... You are so annoying!... I hate you!... You are a bad guy... Ah...
Mmm… Such a lecherous… lecherous brother… Mmm…

I started to fuck her with irregular movements, thrusting in and out shallowly for a few times, and then thrusting hard all the way in: Ah…..Ah…..Ah…
I held my little brother in my hand and inserted it into her wet hole, stirring it left and right, and thrusting it back and forth. She couldn't control herself anymore and started to scream wildly:
"Ahh...so good...yeah...
Brother...I'm going to die!...Ah...ah...ah...ah...ah...ah...I can't bear it...ah...bad brother...it feels so good!

It was really not easy to stir left and right in her tight wet hole. It was so tight that my little brother felt a little painful. I stopped stirring, touched her wet hole with one hand, and thrust my dick into her wet hole, rubbing her wet hole quickly with my fingers. Once her wet hole was stimulated, she couldn't help twisting her buttocks and thrusting up to cooperate with my movements: Ah... Brother...
So exciting...I can’t bear it anymore...ah...ah...ah...ah...so comfortable...I can’t bear it anymore...ah...

I saw her screaming more and more lasciviously, so I teased her: "Are you a slut?"
She has lost her mind: Ah… I am a slut… I am my brother’s slut… Ah… Yes, my sister is… is my brother’s… my brother’s!… It feels so good…

"Slut, will you let me fuck you every day from now on? It seems that such obscene words are very exciting to her~!
I…ah…ah…slutty…slutty sister lets…fuck brother every day…brother~!…It feels so good…I’m going to die…ah ah…~!
Little slut, I'll kill you!
Jun twisted his hips: Ah...brother...quickly...fuck me to death...ah...brother...quickly...quickly...fuck me to death...ah...ah...I just like...ah...I like to give brother's...big...big cock...big dick...fuck...ah...ah...~!
The more lewd Jun said, the more excited I felt. I rubbed my fingers on her wet pussy at the fastest speed, and my big brother also increased the speed of thrusting: Little wet pussy, so much water! She became more excited, and twisted her plump buttocks harder: Ah... You're killing me... Ah... Little wet pussy... My little wet pussy is specially for my brother to fuck... Woo... Ah...
Ah…mmmm…wuah…~!
Her whole body began to tremble again. Was she going to have another orgasm: little wet hole! She answered me in a trembling voice: Well...brother...brother...I...I ah...well...I can't take it anymore...I...I'm coming again...ah...well...quickly...brother...fuck me harder...fuck me to death...ah..."
She reached another climax and hugged me tightly again. I hugged her, and my little brother felt the trembling of her third climax while thrusting in and out slowly and gently. This climax made it impossible for her to breathe. She didn't even have time to rest, and she trembled and moaned: Ah... ah... bad man... bad brother... I'm going to die... ah... don't... ah... you broke me... ah...~!
(Oh…Brother…I feel so good…Brother…you really make me feel so good…Oh…it feels so good…I’m about to…I’m about to…orgasm…I’m dying…This time, under the fierce penetration, I can’t hold back and ejaculate…
(Sister…sister…I…I am also…I am also about to cum…I am about to cum…it feels so good…)
Of course my sister also wants to climax together......
(Brother, hurry up…cum…cum…cum into my womb…hurry up…I’m almost cumming…I’m cumming…oh…brother…brother…I…love you so much…)
Time seemed to stand still, and everything stopped in an instant...
As the semen slowly flowed out of my sister’s hole…
She kept kissing me...kisses and sucks my tongue...She also said...Brother...you make me orgasm continuously...it feels so good...
We hugged each other without moving. After a while, my big brother softened in her wet hole and slipped out of her wet hole. I licked her wet hole clean and she looked at me lovingly:
"elder brother"
I looked at her:
"kindness"
She kissed me on the mouth:
"I just couldn't control myself and cried. It's so embarrassing! Brother, I'm thirsty! Yes, Jun! I'll feed you!" I said, picking up a bottle of mineral water from the table beside her bed. I was thirsty myself, so I drank a few gulps first, then took a sip of water and fed it to her mouth.
Then we took a bath together, dragged our tired bodies to her bed and fell asleep in each other's arms!
