Affairs with my girlfriend's sister


    Chapter #1

    Been reading up in sbf for quite some time. Back then when I was 21, my girlfriend was one year younger than me. We were together the 5th year and I somehow get to know her family quite well. She had one elder sister who is kind of anti social thus I did not really talked to her in depth. Her younger sister was 14 the first year I met her. Just that usual secondary school girl you see in her uniform. Of course I did not bother much about her neither do I have any sexual thoughts on her at first. There’s this Chinese saying 女大十八变. Which also means a girl Change a lot as she grows. Seriously I couldn’t deny this fact. When she turn 18 she changed into another lady. From that young girl who seems so quiet and innocent. To someone who dress to kill. Everything seems to be fine.. Until that very day, everything seems to changed.

    Hi guys, I’m back. Thanks for supporting this thread. It’s not that completely true but it did happened to me years back. Hope you bros will like it!

    Judgement day [ PART I ]

    On that fateful day, I was having dinner with my girlfriend at Dempsey hill. My girlfriend phone rang. As a sensitive boyfriend I took a quick peek to see who it was and apparently it was her sister. I didn’t think much into it. Slowly my girlfriend became very worried and I saw her counselling her sister. I shall name her sister J and my girlfriend Z. Z told me that J quarreled with his boyfriend and is crying hysterically. So we quickly finished our meals and drive to cineleisure to fetch her.

    After a short drive we arrived there and she boarded my car. She was quite calm as she might felt embarrassed breaking down infront of me. At that point of time, all I can rmb is how short her skirt was as she walked towards the car. My god. Her legs… I don’t know about you guys but I’m somehow attracted to slender legs and J’s leg was seriously too hot. The leg that is every guy’s dream. After around 30 minutes drive we reached jurong west. We sat under their block to chat till it was 1.30am and her sister was all the way telling us how upset she is when the boyfriend scream at her saying she’s a inconsiderate lady. Well, to be frank she wasn’t. The guy is asking too much. Damn him, a gem and he can’t treasure.

    Suddenly my girlfriend initiated to go home as she got work the next day which I agreed too but her sister started screaming again saying that she don’t wanna go home early and starting blabbering some shit to her Z’s ear. I was like. What the fuck. I am fucking tired already. Just when I was feeling pissed my girlfriend pulled me aside asking me if it’s possible to accompany J as she’s not able to and maybe as a outsider that is not that close to her she will be more rational instead of breaking down all the way. Well, somehow it wasn’t a choice. So I send my girlfriend to her doorstep as J waits below. Upon our usual hug I went down to talk to J.

    Me:hey, cheer up man. I know how you’re feeling. Quarrels are inevitable, just learn how to give and take.

    J: no… I have not said out the reason behind the quarrel yet, Idw to tell Jie cause I dw to get mocked by her after these ends.

    Me: so by saying these.. You mean you don’t mind getting mocked by me? I said it jokingly.

    J: c’mon la please I trust you. I have been observing your character and you’re a nice guy. I believe you’ll not mock at me.

    Me: since that’s the case why not go straight to the point?

    J: my boyfriend went to club and end up having sex with a friend of mine. Fuck leh, seriously. Then I question him he say he drunk. I scold him after that he say I unreasonable.

    Me: what?! And you’re still with him? Break leh still need to say meh!

    J: I feel very buey kay yan. Can you bring me for a spin?

    My god still got a long way to go! Stay tune!!

    Thanks bro for helping me up my reputation! Motivates me to share more! Do continue to up if you like the story!

    Judgement day [PART II]

    Me: where you wanna go?

    J: somewhere where I can shout and also quiet enough.

    Without further discussion she took my car key, unlocked and sat inside the passenger sit looking at me. I went forward and asked her where she wanted to go. She kept quiet and look out of the window. So, I decided to go mount faber and she wants to be quiet. Along the whole journey, she kept mum all the way. It was kinda awkward as my eyes somehow got glued to her legs. Finally when we are near to keppel I broke the ice.

    Me: you not scared I bring you go sell?

    J: I know you won’t. I trust you. You’re the nice boyfriend of my sister.

    Me: what is that supposed to mean? Wait I park first.

    After we park we walked around looking for a nice spot to chill. Ended up.. Ants la… Dirty… A lot of grass… Disgusting… Fucking princess attitude. She suggested to head back to the car. As she is my girlfriend sister, there is nothing I can do except suck thumb and obey. I open the back seat due to some habit you guys should know… She was like..? Where you going? I was shocked myself as I didn’t know what I was doing. Probably too tired. I acted calm and suggest that it’s more chilling behind as I won’t have a steering wheel to block me from relaxing. She kinda smiled and followed to the back seat.

    Me: so.. As what you said.. Your boyfriend fucked a girl in the club behind your back and blamed you. Don’t mind me asking you, are you still a virgin?

    J: *looks at me with that face like she commited a crime*

    Me: c’mon la, I’m treating you as an adult, a friend. Don’t worry. Whatever we say is between us. It’s not a very disgracing thing. To be frank me and your sister ain’t that clean like it seems to you. We hide from you cause you’re still young last time.

    J: oh.. I’m not.. I lost to him a month ago. It was horrible.. I didn’t want to. But I really loved him. I don’t wanna lose him. Eventually I gave in.

    Me: it’s good ah, like honestly how’s a couple gonna survive without sex? Sex is important to a relationship and it really improves relationship.

    *looks at me feeling lost, question mark on her face*

    J: you sound so different.. I thought you and Jie never had sex. Guess I was wrong. You sound experienced. He always complains idk this and that. Ask me to watch porn. I really don’t know how this shit works. He just fuck me and then say I should watch more porn. I felt like a prostitude.

    Me: don’t worry man everyone started from novice. No one is born to be good on bed. Do you really mind describing what you guys did?

    *honestly, I had an hard erection*

    J: he says I can’t do anything. What handjob blowjob and boobjob I don’t even understand. Why not you tell me how you teach Jie?

    Me: WHAT?! I didn’t teach her.. I literally did it with her.. It’s not possible for me to explain to you by words. Sorry.

    J: it’s okay I understand. Why not you describe from porn? My boyfriend forced me to download some on my phone. Can? I don’t wanna lose him. I wanna be the one that can satisfy him. Please.. Take it as I’m begging you. I’ll treat you a big feast after I win him back from that fucking slut that took his dick.

    I was fucking shocked. Which lady would have like porn on her phone. This young lady here. The innocent girl whom I use to treat her mentos is asking me to describe how sex is done through porn. Yes she’s hot but I can’t accept the change. It was too scary to be true! Like if it’s not me, she might just get raped by other guys if she did that. I wonder she’s dumb or just plain innocent.. She on her phone and I plug the phone to connect to my cars speaker. We started watching a porn about a milf being horny and then a neighbour fucks her. The moaning is like stereo effect! ‘Ahh ahh ahh ahh ahhhhhh…’ All the way.. My dick felt like it’s burning. I swear upon god I’m fucking horny. Looking at J, she was very focus on it. Just then she happen to notice my erection and stare at me.

    Me: sorry! Really sorry. It’s my natural reaction, I can’t help it.

    J: it’s okay, I understand. How she suck his cock until the guy feels so good? Got difference meh?

    Me: there’s a way la.. But how I show you… Fuck I think if we continue I can’t take it anymore. Sorry J we carry on another day? I’ll send you home.

    Just then she hold me back. ‘Please stay.. Please. You’re the only one that can help me.’ Fuck man, idk what but I know I can’t carry on like this. I can’t take it.

    J: I’ll do it on you. Keep it a secret and don’t tell Jie. I just want you to correct me. That’s all. I’m not doing it all the way.

    Me: whatever you say!

    I let my dick took control of my mind. Unzip my pants, and my erected dick came out like a tiger released from cage. She stare at me and I was like, do whatever you want and let’s end this. It’s too much for me to handle. Slowly she bend down and held my dick. Never have I felt so horny before. Just when the fingers touched my dick, I can feel her temperature, the heat. She started to put her mouth inside my dick. Just then I realised.. Her lips didn’t even touched my dick. I was like..

    Me: sorry but you’ve to literally suck, like a lollipop. It’ll be better if you’ll be able to lick it while sucking. Just treat it as a lollipop.

    She bend forward and did as I say. My heart stopped for a second. Gosh! She was doing it perfectly. What more, she had her tongue stud on and I was seriously too satisfied. Just then she stopped! FUCKKKK. Now she have brought me to these stage and she sit up and talk to me like nothing had happened. I realised, she’s really just treating me like a labortory mice. Once she sees that I’m enjoying.. She’s done. She adjusted herself and thank me for it. My dick was still standing so straight that i could feel the energy in it. Instead of wearing my pants I started masturbating.

    J: what are you doing.. Please rmb you’re Jie’s boyfriend!

    Me: I’m sorry I can’t control it anymore.. I’ve forgotten to tell you I’ve a fuckibg high sex drive..

    I pulled her over gave her a kiss on her lips. Immediately, I got a slap on my face. She started to resist ‘WTF WE ARE NOT GONNA FUCK’ I ignored her resistance and carried on pushing my tongues into her mouth. Suddenly she grab my dick hard! I mean REAL HARD. I stopped and look at her. ’ just a handjob, that’s all’ she grab my dick once again, stroking it up and down. Our tongue engage into a tough war. As I was about to cum.. She whispered into my ear ’ you’re really big ‘. Upon hearing this.. My sperms shot out like it’s free from jail. I looked at her.. Things started to get awkward. We clean up the mess in the car and head out for a stick.

    Me: sorry I got too carried away. It’ll be between us right?

    J: yup.. I understand.. Somehow.. I couldn’t control too. I just suddenly wanna help you out. I’m sorry too. Please keep it from others. No one should know about this..

    Me: of course, I don’t wanna lose your sister! Anyway you’re doing it right just now. Too right to be true. Your stud helps a lot. Just rmb to suck it like a lollipop. Trust me he will like it.

    J: thanks a lot. I’ll take note of it. But how to show you if I did the right thing to him?

    Me: you video down la haha! Then I help you see if you’re right.

    J: wtf seriously? Use what? Hand phone meh?

    Me: webcam la, like the Taiwan guy who fuck a lot of woman and record it. Lol!

    J: okay la let’s go.. It’s late alrdy.

    Obviously I was just joking about the recording thing. I send her home and spend another 15 min apologizing to her under her block. She gave me a kiss before she went home. While driving home I can never imagine what just happened to me. Guess what it’s 6am when I got home. After lust what’s left is guilt.

    Two days later I recieved a text from J…

    Stay tune. Gosh I typed damn long.. Goodnight bros! Will update soon!

I have not mentioned that my gf and I have been focusing too much on career and neglected sex during that period of time this explaining the horny me. So you guys ready? Let’s carry on.

    Video

    ‘—’ = Message content

    J: ’ hey are you out with my sis? '

    Me: ’ nope J yes is there anything? She’s too busy with her ongoing things to meet me. Anyway, it’s damn early now. No school? '

    J: ’ I’m in school, can you meet me later? My boyfriend got gathering with friends at 4.30pm onwards and I’ll be free. I did as you say alrdy. '

    Me: ’ dafug seriously, you’re still with him. And anyway what did I asked you to do? Just nice lo, your sister is telling me she can’t meet me as she’s tired from work. Need tell her I meeting you? '

    J: ‘VIDEO LA ASS. Don’t tell her la siao. Wanna sabo me ah. Better keep your mouth shut to her on these stuffs!’

    Me: ’ YOU REALLY VIDEO?! YOU CRAZY OR WHAT! He allowed ah?! Okok meet alrdy then say. I’ll be free after 6. Meet where? '

    J: ’ I very sleepy leh class is bored. We go somewhere I can rest? '

    Me: ’ okay I’ll plan and pick you up later. See ya. '

    J: ’ Seeyou. Don’t tell jie. '

    Obviously I couldn’t even focus throughout the whole day at work. My mind is all about what she video. Seriously, inside me there is one party telling me stop all these and not be so fucked up. Another party is like, c’mon la not like as if you are wrong or what. She initiated what. Fuck I don’t know how to explain the feeling that I’m going through at that point of time. Well, human instinct asked me to bring her to a hotel. I met her at bedok and eventually geylang was the nearest hotel that came to my mind…

    J: eh what are we doing in geylang?!

    Me: you say want rest right. Nearest hotel what? If not you wanna go ikea and lie on their showroom?

    J: fuck what is people see?! Eh you don’t crazy leh.

    Me: eh not I want de leh. You tell me lo. Where you wanna rest. Seriously, if you’re uncomfortable I can send you home.

    J: hena hena, no hanky panky ah. I 18 leh enough age meh.

    Me: c’mon is you initiate to meet de leh. I never had that in mind. Enough la you think go dragonfly ah?

    J: you’re an asshole.

    We park at a carpark near lor 19 and went to 星光. A not bad hotel I’ve been to a few times. Head up to the room straight and there’s this weird silence. And we went in the room. I can feel my dick starting to get harder and her skirt is still as short as ever. Smlj. Guess she love to flaunt her legs as well. We sat on the corner of the bed and she took put the phone and showed me a video. She really used her webcam to video it. Whoever who watched the Taiwan guys leaked video. ITS THAT EXACT KIND OF SHIT. She just passed me the phone and say ’ NA’ my eyes pop out when it started. The video started by her pressing the start and walked back to his boyfriend on the bed eating potato chips. She climb on top of him and took away the chips. The boyfriend immediately got the meaning and took off his specs. *i feel like watching a porn* she directed him nearer to the cam and started making out. Like less than 20 sec the guy took out his dick and dangle it in front of her face. *fuck man no foreplay for her ah* I thought to myself. She happily placed it into her mouth and did as what I’ve taught her to. Slurping sounds got louder and louder.. My dick got harder and harder.. So I lied down and took the blanket to cover it. This continue for another 6 minute plus and finally she stop sucking. At this point of time the guy is damn erected. Just as the video shows her boyfriend pushing her on bed, J snatched the phone away. ’ NO MORE FOR YOU, NOW TELL ME WHAT IS WRONG’

    Me: huh? No more? The video still got 12 minute leh.

    J: the rest cannot be seen la please. I only wanted you to see if I sucked correctly. Eh he say I improve a lot leh. Got hor! Your trick damn good. Jie also always like that ah. Sian if not you teach I sure disturb her.

    Me: hena now haolian lo, know abit then yaya alrdy. Kay la can pass, no need me teach alrdy lo. We better be like last time. Don’t get too close.

    J: you confirm like that enough not. Okay lo.. Anything you say. I feel damn guilty to Jie after that night. Okay la I go take a short nap. Still got 1 hour plus right. Don’t disturb me ah I wanna rest.

    Just then.. I had a dirty idea. I waited for 30 minute after she sleep and I took her phone and unlocked it. Password was easy.. Saw her drew the pattern for dk how many times. I tried to wake her up to test water see if she’s in deep sleep, apparently. She tsk me and cover herself with blanket. I happily open the video and carry on from where I stopped. My god. I never regretted opening it. The boyfriend started stripping her till she was naked.. Slowly.. The top was gone revealing the bra.. The jeans removed revealing the sexy lace undies.. The bra removed revealing her cute boobies.. The undies removed revealing her pussy.. There she is.. Naked. Fuck man, once again I can’t take it anymore. I went into the toilet and started masturbating. The guy started fondling with her tits, sucking it out. I guess he didn’t do a good job as J was not really that aroused. Fuck man, it’s the best porn I’ve ever watched. After another less than a min, J boyfriend tried to insert inside but seems to get stuck. Like wtf man she’s not wet yet dude. But he used his saliva to lubricate and then stuck it in. Oh she started to moan.. Pain.. Pain.. PAINNN!! Stop it.. Please it’s hurting me.. Can you be more gentle..?! It is so obvious that she’s really uncomfortable and guess what the boyfriend replied..? ’ fuck you bitch stop acting I know you’re enjoying it!’ Such a small dick with such horrible skills thinking that his gf is enjoying. Poor dude.. Well I ignored it and carry on masturbating. Imagine if it’s me how I’ll satisfy her. Just then J open the toilet door. Fuck I didn’t lock.

    J: OI WTF WHY YOU TAKE MY PHONE?! *came in to snatch it*

    J: fuck you seriously, I said you can’t watch right. Cb I never go edit away cause I trust you leh. Disgusting fucker. Never did I know you’re so fucked up.

    Me: sorry.. I quickly ran up to her. I don’t mean it. I was really curious cause I realised your boyfriend like can’t satisfy you that’s why I wanna see if I’m right. But you’re too hot. You’re in a hotel beside me eh, if I really want I would have touched you right. I go toilet because I respect you and I don’t want to break your trust eh. Sorry.. *just then.. I heard loud voices of moaning opposite the door*

    Unknown china lady: ahh.. Kan wo(fuck me) ahh.. Ahhh shuang(shiok) shuang( shiok) buyao ting( don’t stop )

    Moment of silence….

    Me: that’s why you woke up..?

    J: yes and caught your pervertic act. Sicko.. Don’t let this happen again. *delete video*

    Me: sorry it won’t. Your boyfriend really sucks what you got so shiok like her meh? *moaning carries on*

    J: no la siao. She prostitude leh. You okay not?

    Me: please leh your sister also moan like that when I lick her pussy. You calling her a prostitude?

    J: wtf, disgusting. Lick pissy?! Nice? Gosh.

    Me: please la you’ve never even been wet you want tell me these. Kao.

    J: how you know? I got okay. But lick pussy leh.. Wtf sia.

    Me: you want me to teach you that too?* I started to stroke her thighs..*

    J: don’t like that leh please.. Put your hands off.. * while saying this her hands are not stopping me..*

    Me: *decided to test water* c’mon la.. It will be another lesson only.. Secret? *puts my hand in the skirt*

    Chapter #7

    Inside me I was like WTF HOSEH LIAO LA! Once again, I lost the guilty feeling and pulled up her skirt. What I’ve just saw in the toilet is coming in front of me. The moaning of the opp china lady makes me fucking excited. I took off her panties and started rubbing her pussy. She was feeling kinda weird I guess she tries to escape but she can’t and she’s smiling like I’m tickling her. Just than.. The opposite lady stopped her moaning and their room was quiet. I took out her bra and used it to tie up her hands in order to avoid her from pushing my head away. She was like a small little girl being tickled laughing madly. After I tied her hands I started licking her pussy, pressed her down. ’ AHH. Wtf! WHAT IS THIS.. UGHHHHH… UGHH UGHH UGHHHH AHHHH!!!’ I can tell you she’s fucking wet. Wet like I’ve been doing foreplay for 30 min when it’s like 5 mins only. She started to get comfortable and seems to be enjoying it.. Her moaning got louder and louder as my tongue were playing with her abalone. Well to be fair I asked for a 69. To my surprised, she’s not the girl scolding me I’m the toilet anymore. She turned around placed her pussy on my face and sucked my dick. Oh shit.. Finally. She’s turned on, I know I won the mental battle. She started sucking.. I carried on licking.. Her nice ass in infront of my face now. I was enjoying this wonderful pussy and yet suddenly! She camed. She squated up and goes ’ AHH!’ I didn’t expect it coming.. So didn’t she.. She lift her ass up and all the liquid splashed on my face. Immediately she was shock and apologized! Sorry I don’t know why I will urine! Fuck! Wash up now!! Sorry!! This is really so cute.. At the point of time I ignored all cries. Push her down and slide my dick up her hole. Look at her in the face. You’ve just reached your orgasm. Now it’s mine. She still looked puzzled but before she said anything I started to thrust inside.. Slowly.. Slowly… Her face showed me a word.. Enjoyment. Her moans.. Her cries.. Begging me to fuck her more.. I can’t resist that man. She’s fucking horny. I swear. I untie her hands and removed her top and bra. Revealing her cute boobies.. Oh no.. She’s near to perfection.. Her innocent moans.. Her pussy is so wet you can hear the ’ squish squish’ sound during every thrust. Heavenly feeling. I Carried on for awhile and finally I came on her tummy. She looked at me and I looked at her.. Our tongues engage into a fierce war and eventually, Both smiled and went to the toilet to clean up. Silence all the way and we decided to head out. As we left, we saw the couple opp our room. They were leaving too. To my surprise, they were workers from the frog porridge just below. Awkward moment as the four of us step into the lift.

    The guy spoke ‘you two very loud’

    Me: so are you? Haha

    Four of us started laughing out loud. I realised J have changed. She no longer treats me as her sister boyfriend. She hugs me in the lift when she see the lady hugging the guy. After we checked out. We bid farewell to the couple and head back to my car.

    Me: so where do you wanna go. It’s 9 alrdy. Your sister never text me at all wtf.

    J: my boyfriend also. Got brothers no need me. I can’t imagine what we just did. We just cheated on our partners and worst! Your girlfriend is my sister. Fuck la you la. Cb

    Me: you never enjoy meh. Now put blame on me. I not guilty meh. You just now I fuck you you also like enjoy only.

    J: cause I somehow had a crush on you since young what!

    Me: what?! What are you talking about?

    J: since young I see how you treat Jie. You’re really a nice boyfriend what. I wish I’ll also find a boyfriend like you.

    Me: but.. Yeah.. Let’s go for dinner first?

    So we drove to east coast to have dinner that night…

    Shall carry on tomorrow! Hope you all enjoyed it! Up my reputation to support me! Thanks. Honestly, I’m feeling guilty to my girlfriend. Yes my girlfriend is still my girlfriend no change at all. Me and her sister? Stay tune to know ba?

    Hi guys! Paiseh forget to say. She kept using her bra and too to cover her boobs while we were doing foreplay. That explains why on the second post I removed her top and bra again. Sorry guys. I’m too focus on the image in my mind. So I typed exactly what I remember. Will try to improve on explaining on the scenes in my head! Hope you guys understand that I’m new to writing my affairs online. Thanks for the understanding (;
