Share your SIL/GFsister stories


    Chapter #1

    Hi Bros, im starting this thread because i havent seen any SIL or GF sister chats. Or rather not many people have been sharing about their stories. So i shall start with my own encounter with my gf sister.

    Lets call her SY.

    Recently, i started to notice SY in a new light. I am quite close to my gf family and they trust me quite a bit. Just a short description of SY: Age: 19/Face: Those xmm face with chubby cheeks/Breast size: approx. 32A /Body type: A bit baba

    So, one of the common thing that i always get to enjoy is SY being braless at home. Whenever I am at my gf place i will steal glances at the 19 yo xmm. One occasion i went over to my gf place to help pack her bag for staycation. Now house very trendy to have electronic lock. So i knew the password. I only use it when no was at home and if its urgent. So at time time was 7pm alr. Yes we both worked late that day and couldnt check in earlier. SY was the first one to come home.

    I ended earlier and therefore went over to pack for my gf. As mentioned no one was home. So being a pervert instead of packing for my gf I went to SY room to see if got any goodies. Sadly dont have. So just to get a kick i pull down my pants and lay in her bed rubbing her pillow against my erected bro.

    How shiok to see SY sleep on the pillow with my sweaty cock scent.

    Knn all of a sudden hear the electronic door activated. I faster pull up my pants and try to hide my huge erection. SY came back, sadly not wearing anything sexy just a jeans and t shirt. We greeted each other and i got to packing. SY went directly to her room and left the door open.

    My little bro was not satisfied by rubbing the pillow. So while packing i just decided to act blur and pretend not to know where all the stuff was. Yup i decided to walk in to SY room and ask for help. I used the chance to just walk in on her hoping i can catch something.

    I used the chance to just walk in on her hoping i can catch something.

    I prayed to god to give me something to look at. You onow that feeling when youre so excited you just start to tremble. Well my hands started to shake as i open the door. As i opened i saw the jeans on the floor and a cute cotton panty stuck inside the jeans. As i open further i saw a bra above the jeans.

    Well not the result i was hoping for but better than nothing.

    So when the door fully open SY was in a old and loose spag top and a white fbt. And up there it was two pokies facing me and best part was she was tying up her hair. Chest out arms raised behind her head.

    “Yes? Kor kor?”

    “Oh SY you know where is your jie jie contact lens solution?”

    “SY where is your jie jie make up remover?”

    “SY where is your jie jie bikini?”

    Bingo! Finally something she couldnt find. We spent quite awhile looking for it. So we emptied the bra and panty basket and sat down to find it.

    Ya you guys maybe a thinking knn a bikini only so difficult to find meh? My gf got 5 baskets worth of bra/panties/bath robe/and god knows what else.

    So we started digging through the pile of sexy lingerie that my gf owns. I was thinking to myself wonder when i will SY start to wear these type of panty so i can sniff them.

    Well while i wished she had started to wear sexy lingeries. but aiya these kind of things only happen in movies. What i saw made me a true believer that sometimes movies can become reality.

    Sometimes movies can become reality..

    So being the disloyal and pervert bf that i am. I kept staring at her pokies. I tried changing my position to “search for the bikini” but it was trying to catch a down blouse.

    Just at that moment SY changed her position. Yup she changed to doggy position. Knn my bro sedia instantly. Two full views of her lovely tits just dangling there for me to see.

    I stopped and went to the bed to “check on other stuff” but actually went there to check out her ass.

    The layout is simple. A rectangle room wardrobe is and the far end of the room by the window and the bed is beside the door. So yeah walked to the bed because SY was facing the window.

    Wow.. So back to the scene, SY was in her fbt that rode up so high in that doggy position. And a lovely surprise was waiting. The inner netting of her fbt was not there. And you hiys know what else wasnt there? Yeah, her panty.

    I had a full view of her small round perky butt. It wasnt those perfect butts you see in porn but instead it was a flawed perfection. If you rated a girl a GND her ass would probably be a GND rating. A little bit of marks and could see a visible pimple near the contours of her pussy. It was enough to make my pants bulge.

    I eye raped her further and scanned deeper to examine her pussy. Unshaven but not uncontrolled growth of hair. Those thin layered type not bushy at all. Her pussy lips were nice and thick. I didnt get to see her actual pussy because the lips were covering it up.

    Expert bros here would probably know what type of pussy she has. My little bro was so hard. I guess after coming home from school she didnt replace the panty that was stuck in her jeans

    Didnt know got feedback for more of SY.

    These kind of experiences dont come very often. But what can i say? SY is a growing girl. The way she dress is getting less conservative.

    SY recently got this fbt like shorts. No inner lining, high slit with loose flaps. What i mean is the flaps covering the front and back lifts up very easily. Furthermore the slit goes up quite high. Tease my cock to the max.

    So one night she decided to wear this for me to see. She decided to tease my cock. During dinner keep stealing glances at her legs. Cock want to stand alr. My perverse mind whole dinner keep thinking about her. Wondering if i will ever get to see her pussy again.

    Cut the long story short, after dinner went to the room stripped naked and waited for my gf to come. Best part was my gf decided to talk dirty and guess who she decided to bring into our sex fantasy.

    Yup thats right boys, SY. Not sure if my gf saw me keep bio SY. But its was the perfect moment. I banged my gf so hard while my gf pretended to be her sister. That night bang until my gf also KO. I unloaded a huge load all over my gf ass. After cleaning up both of us fell asleep. But you know those kind of sleep where your mind still awake but body sleeping?

    My pervert mind still couldnt get enough of SY. I woke up about 1 hour later(this 1 hour later i not sure if really 1 hour but for the sake of the story lets just put it as 1 hour lol. Not very important detail but.. you know..). During the 1 hour sleep i kept thinking how to see more of SY.

    After 1 hour of planning my mission i got up. Walked out naked to use the toilet. Good thing my gf KO. Some of you maybe wondering i so daring walk out naked not scared of parents wake up? Well once my future in laws sleep they dont come out of the room.

    I decided to execute my mission.

    1. Check if my gf will wake up: sleeping like a log.

    2. Check if SY sleeping: lights offed quite late at night alr. Should be clear.

    3. Open SY room door slowly: heng the door got oil, no squeaking sounds. Opened the door just nice my body can go in.

    4. Peek my head in to check: knn room so dark and my eyes not adjusted yet.

    5. Still cant confirm if SY sleeping: suddenly heard a sound coming from SY.

    Balls dropped to the cold floor. Dont forget i was butt naked.

    Chapter #6

    So I have been a bit busy and frankly quite lazy to finish the story.

    Well, this isn’t some fantasy story this is real life and my luck not that good until can find a gf sister willing to suck her own sister boyfriend cock. lol..

    So to continue where I left off, my balls touching the floor.. frozen with my head peeking in watching SY throw her blanket off her. She made those like annoyed sleeping groans and adjusted herself.

    Im not sure if you guys have this feeling when doing something exciting or perverted but there is a feeling like you want to take a shit. And it works better than vitagen or yakult. Once you got that feeling you sit at the toilet and auto come out.

    I froze there for awhile to confirm if SY is back to sleep. Went out again to check if my gf is asleep then decided to go in all the way.

    By now my eyes has adjusted to the dark and the moon light was shining in. For some reason i used my army training to walk silently but that only applies to boots. Not sure if you guys remember, but your heel touches the floor first followed by your feet.

    The moment i was at the foot of her bed my shit almost blast out my ass, my legs trembling from the adrenaline like literally shaking. Heart beating damn fast. Cock hard until can carry pail of water.

    When SY adjusted herself previously she was feeling hot from her thick blanket. She lifted up her shirt and exposed her right boob. Her legs was spread open like as if she knew i want to come in naked and stare at her.

    So guys here i am standing butt naked, legs shaking, cock harden in front of the exposed 19 year old SY.

    What do i do next?

    What do i do next?

    There is only so much i can do without risking waking her up.

    First things first i brought my nose nice and close to her loose fbt shorts(without the inner lining) and took a big whiff.

    Mmmhhmmm musky pee smell of a young 19 year old.

    It was dark couldnt see much but sadly she was wearing a normal silky-ish black panties, nothing special.

    Second thing i did was go in for a kiss. Not with my lips, but yeah… with my cock. I decided to lights rub my cock head against her lips which i did. Oh boy.. that rush. Like taking drugs from your cock and you can feel it tingle up your body.

    I pushed my cock to part her lips and slowly slide it up and down. If you guys ever have a chance like this you’ll know how difficult it was not to just jerk off and cum into her mouth.

    That warm lips was heavenly.. but that was a stupid move. The next moment she shifted and my cock went limp i got scared and left the room as quietly as i could.

    Decided to take home SY used panty from the laundry basket and unloaded fully into it. The next day went to her house to put it back.

    Now that i look back, i wish i had done more.

    Everytime during meals when she is eating something that requires her to suck(like chicken wing or ice cream or whatever that will make her lips purse) i always remember that moonlit night where she first kissed my cock.

    Hope you guys enjoy the read. Not very happening but hope to have more bros share their experiences.

    Great stories of your SIL. Hope to see more sharing.

    Recently was at my gf house. Only the three of us at home. My gf, SY and me. My gf and SY was in the kitchen cooking dinner. Then she asked if we wanted to order bubble tea in. At that point of time I was in my gf room playing game on ipad.

    So usually when I’m in my gf room I will just be in my boxers or boxers and shirt.

    That day I was just in my boxers. It was one of my loose boxer. I don’t really know how to explain my sitting position but I was on the floor leaning against the bed with the bottom of my feets against each other. Like when you put your palms together. So basically my legs were spread open and my cock and balls was fully exposed.

    SY came into the room while I was play game. At the point of time I wasn’t really paying attention to what she was saying but she wanted to ask me for my order. I took awhile to reply her.

    “Kor kor which bubble tea you want?”

    “Uhh where you all ordering from”

    “From ***”

    “Orh get me ***”

    To those of you that doesn’t know how my SIL sounds like she sounds like a very talkative 12 year old with a cute high pitch voice.

    It was only after my game ended then I realised my cock was fully exposed and she took my order for at least a good 5 minutes because that was how Long my game was.

    My cock went hard just thinking about exposing my cock to my gf sister. The feeling of shredding her innocence from her and showing her what a cock is. At this point my dick was standing at full attention.

    I thought that was the end of that episode.. so I didn’t bother covering up my fully erect cock. I started another game and my cock slowly went soft. You know the part where your cock still the fully erect size but soft? I think this only applies to guys that grow. For guys that show probably they might not understand (I’m a grower not a shower)

    So my limp but fully erect cock was still hanging out and at that moment SY came back in again to inform me that my drink no stock. Instead of thinking of what to drink next I only could think about SY staring at my cock.

    And yup. When I looked at her I could she her staring at my cock. Wah knn that feeling fucking shiok. I could feel the blood pumping back to my cock. With each heart beat a small amount of blood push my cock up slightly.

    MY GF SISTER WAS STARING AT MY FULLY ERECT PENIS! MY GF SISTER KNOWS HOW BIG MY COCK IS! HAHAHAAH. This feeling really kan song.

    I immediately told her my order then she gave me a orh then left the room.

    Later that night after dinner I fucked my gf damn hard. Imagining I am fucking her sister.

    TLDR: My gf sister saw my fully erect cock.
