I (21[F]) have been getting railed by my brother law (30[M]) for the last year, and now I’m his live-in cum slut. This is the story of how it started.

I’ve never had a good relationship with my older sister. We are 8 years apart so she never really wanted to play with me as a kid because I was too young (but more likely too independent) to play along with her little games the way she wanted to play them. She moved away from our home town when I was only 10 and I had barely anything to do with her from then onwards. It was only 3 years ago when she met a guy and moved back to our hometown that she re-entered my life. This time with an absolute snack of a boyfriend who soon became her husband and now the father of her child.

While I’ve never gotten along with my sister, as she’s a bossy, overly serious, self-absorbed person, my brother in law Hugh is a funny, charismatic, and easy going guy, and we have always got along like a house on fire from the day we first met.

I started to spend more and more time with them after they had their first child a year and a half ago. It would always really annoy me when I would go round to visit or baby sit that my sister would treat her husband like a dog. Yelling and snapping her fingers at him. Nothing he could do was ever right and she was constantly on his case. In her defence though, she treats everyone like that, including me, so Hugh and I soon formed a stronger bond based on muttering under our breaths about her when she would leave the room, and rolling our eyes when she would act especially ridiculous.

My sister soon returned to work a bit over a year ago when their baby was 5 months old, and would go to yoga straight after work on Thursdays, and then have dinner with her yoga pals (because ‘self care’). Hugh would go get personal training on a Thursday night too so a new arrangement began that I would come baby sit for them every Thursday night. It was a pretty fun arrangement, mainly because I got to hang out with Hugh. I would pick up their baby from childcare after uni, and bring him round to their house at 5pm when Hugh would just be arriving home from work. I would help Hugh feed and bath the baby. Hugh would then put the baby to bed and we would chill for a bit until Hugh would head off to PT at 7:30. I would just watch tv, do homework, and chill while the baby slept until my sister would come home at 8:30ish, and she would very bluntly tell me she was “tired” and that I should leave (she’s never been one for wanting to spend any type of sisterly bonding time with me).

The arrangement had been going on for a month and a bit, and each week I would wear something a little more daring than the week before for my evening with Hugh. I could tell he was noticing by the way his eyes would linger on my body, especially when I would bend over or lean forwards. I would always bring with me a loose pair of trackies and a hoody to throw on once Hugh would leave so my sister would be none the wiser when she got home. This week I decided to wear my most daring outfit yet. I was wearing little black booty shorts and a tight low cut practically see through white singlet, with a bright red crop top that made my boobs look great underneath. When I walked in holding his baby, Hugh’s eyes nearly popped out of his skull, it made me smile but I knew he would never actually do anything with me, and that I should just enjoy the rush of having him notice me like this. I made an extra effort to do a lot of bending in front of him and touching him inadvertently to grab things.

Just after feeding and putting the baby to bed, Hugh got a call from his PT saying he had dropped a weight on his foot and he was on his way to the hospital for an X-ray. I was a bit disappointed because just chilling on the couch with Hugh for an hour and having banter was my favourite part of the evening and now because he wasn’t going to PT I would just have to go home. I stood up and started to grab my stuff. Hugh told me I didn’t have to leave and that we could just chill until my sister got home. I asked if he was sure and he insisted.

We put on some Netflix original movie that had just come out. The lead actress was a 6ft tall blonde bombshell and I couldn’t help but remark how hot she was. Hugh laughed “yeah she’s hot, but nothing special”. I pushed for more detail, she was a goddess, what could he possibly not like about her? “Well yes she’s good looking but not my type, at all”.
“What is your type then? Like my sister I imagine? Brunette, slim, perfectly sun kissed skin, prim and proper, not a hair out of place, perfect posture from the big stick up her arse” I joked.
Hugh laughed, and shook his head “uhhh your sister is beautiful, don’t get me wrong, but umm that was never my type before I met her”. He seemed a little embarrassed, but I was having fun with this conversation,
“so what was your type then?”. He paused for a bit and stared intently into my eyes, I could tell he was trying to decide if he should keep up with the light hearted banter, or put a stop to it before he says something he might regret. I reached and put my hands on his legs
“come on we are just having a laugh, don’t worry I won’t tell my sister” I winked.
He smiled, eyes glancing down to my hands still sitting on his legs for a split second and then back up to my face.
“Well, my type was always shorter girls, but with curves, you know…. like with some cake. Also I’ve always loved big hair, there’s something so sexy about it. Skin colour I’ve never really cared about, but I’ve always loved freckles and dimples, they’re so cute.”
Inside my stomach I felt butterflies, had he just described me, or someone like me? I had out of control long curly brown hair, I was on the shorter side of average but firmly pear shaped with a pants size 2 dress sizes bigger than my top half. I also had a smattering of freckles across my nose and cheeks, and one single dimple on my right side. I looked down at my hands, still on his leg, and it almost felt like there was an electric charge keeping them there. He interrupted me from my thoughts.
“What’s your type?” he asked. I could have embarrassed myself and told him that I liked tall, dark, and handsome types like him, but instead I kept it light and playful and responded “All the guys I like seem to be taken, perhaps men that aren’t single are my type, that or I’m just unlucky”.
“Oh yeah”, he responded, “maybe you should tell these non-single men that you like that you’re interested, they might not realise. A beautiful young woman like yourself… I’m sure they might make an exception…”.
I was shocked, was he saying what I thought he was saying. Inside my shorts I could feel myself turning into a puddle. I looked into his eyes for a long moment, giving him the opportunity to change the subject, move away from me, or even just break the eye contact. His stare never wavered so I proceeded with caution.
“So if you were me, what would you do?”, I asked him, putting the ball back in his court.
“Well” he started, “this guy is taken right? So you would want to make him feel pretty confident that you’re into him. Because he isn’t going to risk it all for someone who may not even want to go there”. I nodded,
“How can I show him I’m interested? Would casual touching work?” I glanced pointedly at my hands still on his leg, “how about if I were to dress in a certain way that shows a lot of skin? Would that help show him I’m interested?” I continued, glancing down at my scantily dressed body.
“Hmm those things would help but I don’t think he would be 100% sure yet that you’re interested. He may just think you’re being a flirt or just having a laugh”, he explained. I furrowed my brows and stared at the ground, what did he want from me, he wasn’t willing to admit he wanted me and I wasn’t ready to admit it either. I felt his warm hand grab my chin, and gently lift my head so I was once again staring him in the eyes.
“I can think of one thing, what if you were to go in for a kiss very slowly, and if he pulls away he was never interested, but if he accepts…” he trailed off.
My eyes lit up, I started to inch forward very slowly, waiting for any sign he didn’t want this.
“Like this?” I asked as I kept moving towards his face at a snails pace. He just nodded. I kept getting closer, staring into his eyes, waiting for something, some sign, but nothing came so I kept going. I could feel his warm breath on my face. I paused centimetres from his lips. Working up my courage. My next action was going to change everything, either I would be completely embarrassed if this was just some type of joke to him, or I was going to kiss my sister’s husband, knowing he wanted me to. I took a deep breath, ready to take the plunge, when he pounced on me, crushing me into the couch cushions and feverishly meeting his lips to mine. I was shocked for half a second but my feelings for him took over and I was kissing him back with all the pent up passion that had been developing over the last few months.

His hand slid up my body as he continued to kiss me, it felt like he was leaving a trail of fire all over my body with every place he touched. He ducked his hand under my singlet and grabbed my breasts through my crop top, a moan escaping both of our mouths mid kiss. He expertly took off my singlet and crop top with one hand. My nipples instantly hardened from my arousal and the cold air. He paused our kiss and took one in his mouth, my back arching in pleasure.
“You have no idea how long I’ve wanted this” he said with my nipple between his lips.
“Me too” I moaned in response. He reached down to the apex of my thighs and I could feel his hand through my now soaking wet shorts.
“You’ve been teasing me with your little outfits for weeks. This was all your plan wasn’t it, you little slut”
All I could do was nod as he pulled my shorts to the side and slipped his fingers into my dripping slit. He pumped his fingers in and out as I threw by head back in ecstasy. I could barely believe this was actually happening. Suddenly his fingers left my body and when I opened my eyes I could see Hugh pulling his rock hard cock out of his shorts. I gasped as I took it in. My sister was a lucky bitch. It was at least 8 inches and thick. He pulled me up and directed my head straight to his cock. I took my time licking it all over before putting as much of it as I could in my mouth. I was on the edge of gagging but it felt so good to have my mouth full of him and I could tell he was enjoying it too. I kept going but I could tell he was getting close. After a few moments he stopped me and pulled my head back.
“You’re not going to end this that easily” he laughed. He pushed me back down into the couch cushions and peeled my now soaked shorts off my body. He spread my legs and took a moment to look at me laying there on the couch naked, legs spread for him.
“God you’re so fucking hot. I was never going to be able to resist you.”, he stated.
“How long have you wanted me?”, I asked. I hadn’t realised the long term longing was mutual.
“Since that first day your sister brought me to meet you. You were wearing a stupid little white sundress and I swear to god I would have bent you over that restaurant table right then and there had nobody been around.”
“Well we can make up for that lost time now”, I joked.
“Yes we can”, he replied, as he started to dip his head between my legs and lap up my pussy juices. Feeling his hot wet tongue running along my slit and flicking my clit was heaven. I almost came immediately from the sheer pleasure of it. None of the guys my age had ever given me head like this, it was borderline earth-shattering. He could tell I was getting closer with every pass of his tongue, so he abruptly stopped and rolled me over, slinging me over the arm of the couch. I supported myself there, ass in the air as he rammed his cock into my pussy from behind. My eyes nearly popped out of my head and tears came to my eyes as he drew back out and rammed back in. It was a struggle to stop from screaming out and waking the baby and the whole neighbourhood.
“You like that don’t you, you little slut?”, he asked. There were no words to express how much I liked it, and even if there were, there was no way I could string together a sentence in that moment. He kept pounding me from the behind, with every stroke taking me higher and higher and higher into what felt like the clouds. Just when it felt like I was about to explode from pleasure, he whispered in my ear
“Cum for me, now”. I let go and let my orgasm rip through me, screaming his name. He started pounding harder and faster now as the waves of my orgasm continued for what felt like an eternity. He moaned out my name as he too came apart, stopping the thrusting as he grabbed me from behind and shook with me until our orgasms subsided. After a long moment he pulled back and flopped back on the couch, pulling and twisting me with him so that I was lying on top of him, now with our faces centimetres apart.
“That was incredible” I breathed.
“That was a long time coming”, he laughed at his own pun. I stayed there laying on him for what felt like hours as he slowly and sensually caressed my body. Too soon it was almost 8:30 and my sister would be home soon. He cleaned up our mess as best as he could and kissed me, his lips still tasting like my pussy, as he grabbed his keys and gym bag and got into his car, driving to sit and wait somewhere until it was an acceptable time for him to come home from “PT”.

I threw on my hoodie and trackies and sat on the couch scrolling my phone for 3 minutes or so when my sister arrived home. She waltzed in the door and took one look at me in my comfy clothes and scoffed, “I don’t know why you insist on walking around dressed like a homeless man in your baggy old clothes. I don’t think you’re ever going to get a boyfriend dressing like that. A little bit of style and good taste goes a long way”. I chuckled under my breath. She hadn’t even given me a chance to feel guilty for what I’d done before berating me. I got up heading to the kitchen to get a glass of water, suddenly realising how thirsty I was after my evening with Hugh. She stepped in front of the cupboard where the glasses were kept. “I’d love to stay up and have a drink with you but actually I’m really tired and want to go to sleep. You should go home”. I just nodded and wished her goodnight. I walked out to the car and saw a note on my seat, I must have left my car unlocked. The note read “hey sis, tonight was a lot of fun. I hope you can cum back soon.”

Since that day Hugh and I have gotten to know each other a lot better. His PT ended up fracturing his foot in 4 places after dropping the weight on it so was off work for 2 months. But neither Hugh nor I thought to tell my sister that. When his PT finally did recover Hugh made the decision that he was getting more than enough exercise on Thursday nights and our secret arrangement continued. Eventually COVID hit and I lost my job as a bartender and was going to have to move back in with my parents as I couldn’t cover rent. My sisters job still required her to come in to work physically every day and Hugh was going to have to work from home. My sister didn’t want her son going to childcare during the pandemic as she was afraid he would get sick. Hugh cleverly suggested I move in and look after their son full time, kind of like an au pair, so Hugh could work from home without being interrupted by the baby. This was a win for everyone, but mostly for Hugh and me as I’m now his little live in slut and I regularly spend their son’s nap time/ his lunch break getting fucked all over my sisters home, including in their bed. My favourite times are when everyone is asleep, Hugh will sometimes creep into my room and wake me up with his fat cock in my mouth. It’s always such a struggle not to moan too loudly and wake my sister up.

I don’t know what will happen to mine and Hugh’s little arrangement when this lockdown is finally over but I for one can say I don’t want it to end.

  1. I really enjoyed it, descriptive and with no spelling mistakes. Well written. Could use a few more paragraphs.

  2. Great story and lucky him until you open your mouth about it and it all comes crashing down on him ruining his life that he has goin. But I know he made the decision too. Just rarely can you have that fun and stop without it going unnoticed forever

  3. This was quite the trip, but I can’t stop to wonder, what will you do if she is going to find out?

  4. We both enjoyed the very well written story. It was sexy without being porn. Had a lot of nice details. Thank you for sharing. But as others have eluded to, it will somehow come out. When it does you both better be prepared. It is obvious that once again opposites attract (he and ur sister) but rarely work out. He is obviously unhappy with his marriage but again, you both need to be prepared for whats to cum. Reality sucks. We hope you continue to share with us the progression of your fun. We are sure there is qujte the evolution possible between you and him. Our best to all.

  5. This was an amazing read. You should enter it into the September contest. :)

    Thank you for sharing. I hope we’ll hear more from you.

  6. are you gonna keep sharing stories of you and Hugh its totally up to you but i know me and others would enjoy if you did

  7. I see that this was written by a non American English speaker. I love the suttle differences in spelling and verbiage.

    Love the story too. A non face revealing pic of that hot bod might help us imagine you getting railed a bit more vividly.

    I agree that if your sis is so demanding that she just needs a good long hard banging to bring her back around. The marriage is doomed if all one partner does is control and complain. I think you playing it safe is your best bet.

  8. Probably my favorite story in terms of technical story telling ability. I felt like I was there watching you cum apart. This is so well written in just excited to see what’s next. I know you used a throw away but man I hope to read your next….

  9. I actually am rooting for you, though I generally would take the side of the person getting cheated and lied to.

    But just a word of warning, this is going to end very very badly. There is no scenario that is a happy ending other than you and Hugh quietly deciding to end things and to never ever ever speak of it again, even if they get a divorce.

  10. Great story. A hot arrangement for sure. I hope you are able to keep it on the down low. Well written – I love your sweet and slutty style! :)
