I Am My Brother's Cum Slut, Chapter 1

I always thought my big brother was a pain in the ass... turns out he just wanted it!

I can still remember the day it happened as if it was only yesterday, I had just come home from work (I work as a waitress at the local coffee shop) and I was excited because it was Friday night and I had plans to go out with a new guy I had met earlier this week. Thomas seemed like a really nice guy and he was very handsome so I was looking forward to getting to know this guy and see where it would take us.

Before I get too much further into my story, I guess I should tell you a little about myself. My name is Karen Duwalt and I live in Madison, a small town just north of St. Louis with my mother and father and older brother, Michael. I am nineteen years old, 5'1" tall, with black hair halfway down my back and green eyes.

I rushed home from work and after a hurried "Hi Mom!", I ran straight to my room to get ready for my date. Thomas said he would pick me up around 7:00 pm so I didn't have a lot of time to waste. I quickly got undressed and went into the bathroom to take a shower. 

Dammit, Michael! You left your dirty clothes in the bathroom again! I thought to myself as I entered the bathroom and spotted the pile of dirty clothes beside the tub. Michael had this bad habit of leaving his clothes wherever they fell and it was usually either in his bedroom or in the bathroom. Our home had two bathrooms - one for Mom and Dad and one for me and my brother. And my brother used our bathroom as his own dirty clothes hamper!

With a heavy sigh of disgust at my brother's lack of responsibility, I picked up his dirty clothes intending to take them the ten feet or so across the hall to the laundry room. But when I picked them up, something completely unexpected happened.

I had gathered his shirt, t-shirt, and pants in my arms and reached for his boxers when my hand touched something cold and slimy. "Eww, gross!" I said as I recoiled my hand in shocked surprise. But then I reached down to pick up the dirty garment and, for reasons I still can't explain, I looked at the milky-clear jelled substance in his shorts.

It looked innocuous enough... kind of like mayonnaise that had been left out too long. My curiosity stirred, I touched it lightly with my fingertips. It was slick and slimy, but not altogether unpleasant. However, what struck me then was the faint smell I detected. I raised the garment closer and took a sniff.

It was a moment that would change my life and define who and what I was to become.

As I stood there in the bathroom holding my older brother's sex-soiled boxers to my nose and inhaling the musky scent, something inside me awoke. I felt a stirring deep inside me and my pulse increased, my breathing got shallow, and I felt a familiar but unexpected twinge in my pussy. 

I was getting turned on sniffing my brother's underwear! I knew it was wrong, that this was the act of some kind of sick, twisted pervert. But perhaps the wickedness of it all was part of the appeal. I was breaking about every taboo I had been brought up with. Yet this was so exciting and sexy that I couldn't bring myself to stop!

Now don't get me wrong, I'm no prude by any measure. I've had my share of boyfriends and seen a cock or two in my time. I lost my cherry at sixteen to a high school football player two years older than me and I haven't looked for it since. I enjoy sex as much as the next girl and maybe a tad more. But this was a twist that I wasn't expecting!

Almost without realizing what was happening to me, I found myself with my hand in my panties, the only clothes I was wearing as I prepared to take my shower. I rubbed my dampening pussy with one hand and held his boxers to my nose with the other as I breathed in Michael's intoxicating scent. 

The whole scene made me lightheaded, and I had to sit down on the toilet as I tried to sort out what I was feeling. I rubbed my sopping pussy vigorously as I took in his aroma, quickly bringing myself to a thunderous orgasm - one of the best I'd ever had! I was too weak and wobbly to walk much less stand up long enough to take my shower, so I sat there for several minutes until I calmed down enough to continue.

I finally managed to get my shower taken and get ready for my date, although honestly, I don't remember a whole lot about it. While I may have been out with Thomas physically, my mind was back home in that bathroom. I couldn't get over how incredibly turned on I had gotten sniffing my brother's cummed-in shorts.

I thought about what had happened and what it meant. Was I actually a closet pervert and didn't know it until now? What would my family think if - God forbid - they would find out? St. Louis is right smack dab in the middle of the Bible Belt and people here are ultra-conservative; they don't go in for the wild sexual kinks and quirks found in more free-thinking and adventuresome places. They certainly wouldn't understand something like this!

Yet as sick and twisted as this was, I couldn't help thinking about it and getting excited about the whole wicked, depraved thing. Whether it was the wickedness or the danger or what, this new kink of mine was all-consuming! 

I knew my older brother had had several girlfriends and had even had sex there at the house ( Mom and Dad didn't know it, though!) and I had noticed him noticing me a little more now that I was older, but I thought nothing of it at the time. 

So I wasn't too worried about the fact that he had blasted his boxers in the bathroom. I wasn't even mad at him anymore for leaving them there for me to find. What disturbed me was my own reaction to finding his "present".

The events of the day haunted me for the rest of the evening and into the night. I replayed the scene over and over in my head and I don't mind telling you that I got just as worked up as I was that first time. That night brought several rocking orgasms as I thought about what I had learned about myself. There wasn't much sleep for me that night, but I did greet the morning with a satisfied smile on my face!

*

I was able to get through the next day with a modicum of self-control - at least until dinner time. Michael had grabbed himself a quick breakfast consisting of a cinnamon roll and a glass of milk that morning so he was gone by the time I got to the breakfast table. But dinnertime that night was the first chance for Michael and me to sit at the table together. And while he wasn't aware of what had transpired, I most certainly was. I couldn't help but shoot him furtive glances, looking away quickly when he caught me, too embarrassed and self-conscious to lock eyes with him for even a second. 

Not much was said that evening at the table, which was a little odd for us since the table is where we usually caught up with one another and talked about our day. Mom, Dad, and Michael were all up for chatting, but I was too afraid of my own voice betraying what was constantly on my mind lately.

After dinner, I decided that it would be prudent if I got away from the family for a little bit before my mouth got me in serious trouble. So I decided it was a good time to take a shower and went into the bathroom to try and cool down. But my plan was thwarted almost immediately when I spotted a pile of dirty clothes on the bathroom floor again. 

But this time it was excitement, not aggravation, that I felt when I saw the crumpled clothes. I knew by looking at them whose they were, and I went straight over and rummaged through them until I found the object I was looking for. 

I was not disappointed in what I found there either... Michael had shot a load in his underwear again and I was lucky enough to find them before Mom washed them. 

I brought them to my nose, inhaling deeply the musky, pungent scent of male sex. And just like before, the smell of my brother's "gift" was too much for me to resist. My hand went straight to my dripping pussy and I fingered myself to a crashing orgasm. But this time, just as I was finishing, I heard the distinctive "click" of the door as the latch closed!

Oh my God! I thought as I clamped my hand over my mouth to stifle any sound I might make. Who had that been? Was it Mom or Dad? Dad probably would have interrupted me asking just what the hell I was doing, and Mom would have shut the door a lot harder, ashamed of what I was doing. Then another even more alarming thought occurred to me... what if it was Michael who had come in? What if he saw what I was doing with his clothes?  How much did he see?

I went straight to my room after my shower and stayed there the rest of the night. I was afraid if I came out to be with the family, the first person who spoke to me would see my beet-red face and know something was up. Mom came into my room after a while and I made up an excuse that I wasn't feeling well and was just taking it easy. She bought my flimsy excuse and I was left alone for the rest of the night.

However, later that night after everyone had gone to bed, I was laying there in my bed, still scared to death that someone caught me with my kink. How would I face the family after this? Would they even want to face me, to acknowledge me as a member of the family?

Suddenly, I heard a soft knocking at my door. I pulled the blankets up tight around my chin and didn't make a peep. I mentally kicked myself in the ass for leaving the light on in my room and silently willed it to turn off so that whoever was knocking would think I was asleep.

"Sis? Are you asleep?" Michael said, cautiously peeking around the door. 

"No," I said. He had seen me so there was no use in pretending.

"Can I come in... and talk?" he asked quietly.

"I suppose. Are Mom and Dad still up?" I asked.

"No, they've gone to bed. They think I'm in bed too, but I wanted to talk to you," he said, coming in and shutting the door. He walked over and sat at the foot of the bed.

I didn't say anything at first, wanting to hear what this was all about before deciding how to respond.

"Karen, I... I saw what you were doing... in the bathroom," he started. Right there my heart dropped to the floor. He was the one who caught me!

"But I'm not going to tell Mom and Dad, don't worry about that," he finished.

"You're not?" I asked unbelievingly. Michael and I had always had a rocky relationship, with me being the girl of the family and him being older than me, there was always a competition for our parent's affection and attention. To learn that he knew this terrible secret and wasn't going to use it against me was almost too good to be true!

"No, I'm not," he said. 

"Why not?" I asked, now getting a bit suspicious of my brother.

"Well, Sis, I saw how much you liked it and I saw what it did to you. And since it's not hurting anyone else and not bothering anyone, what's the point in saying anything. If it makes you happy, then knock yourself out, I say. Besides, you know that I... umm... I jerk off in my underwear," he said, looking down.

I wasn't sure at this point which of us was more ashamed of our actions. Him for jerking off into his shorts, or me for enjoying them afterward! But I was just happy that he wasn't going to tell our folks.

"Really? You won't tell Mom and Dad about this?" I asked.

"No, I promise. But you have to promise not to tell on me either," he said.

"Deal. Let's shake on it," I said. And we shook hands sealing the deal. But I pulled him closer and when he came to me I gave him a big hug "Michael, if you ever want to talk, I hope you will come to me and we can talk about anything," I said in his ear.

"Okay," he said. I gave him a sweet kiss on the cheek to show my gratitude.

"Aww, Sis cut that out!" he said, wiping off my kiss. But I saw a smile on his face that let me know he didn't really mean it. Then he left and I felt a tremendous weight go out the door with him. That night I slept better than I had the last couple nights.

The next couple days were uneventful. Michael and I talked liked always, perhaps a little better. We shared a few secretive smiles that caused Mom to pause and wonder what was going on, I'm sure. But she was just happy we were getting along and didn't say anything. 

"Sis, I'm finished with my shower if you want to take one," Michael said one afternoon. I was in my room watching TV when he popped his head into my room to make his announcement. I looked up and he had a big goofy grin on his face. I instantly knew what he meant and I quickly got my things ready to take my "shower". As I went into the bathroom I saw that old familiar pile of clothes and I smiled - Michael had left me a little "present"! 

Knowing that Mom and Dad weren't due home for a while yet, I didn't shut the bathroom door fully. If Michael was the voyeur type, I would give him a show! I stripped out of my panties and stood there with my back to the door sniffing his boxers. He had left me quite the load this time - evidently, he had been saving himself for a good load the last couple days! His boxers reeked of man-smell and I breathed him in deeply. I rubbed his cum-laden boxers across my cheeks and over my tits, making my nipples so hard they could cut glass!

My hand slid down my belly to my drenched pussy and I moaned aloud at how good it felt to have my fingers there. That's when I heard the bathroom door slowly open. I turned to look and I saw Michael standing there, silently watching with the door half-open.

"Come in," I said, smiling wickedly. I curled my finger in a "come here" motion and Michael came into the room.

"So you like to watch do you?" I asked, "Well how about I give you a show then?"

"O-okay," he said, stammering nervously. I put my hands on his shoulders and pushed him gently backward until I seated him on the toilet.

"You just sit right there, the show is about to start!" I said. I had seen enough movies and Internet videos on lap-dancing that I was fairly certain I could give a good enough show so that's what I did. I was already fully undressed so that part of the show would have to wait for another time, but I moved closer and wiggled my tits and shook my ass at him which seemed to please him well enough. 

Now I'm not built like a pornstar by any means. I have 32C tits and my ass is nice and tight. I haven't had any complaints from the guys I've dated although I wish my tits were a bit bigger. But Michael seemed pleased enough with them. As I shook my tits and ground my ass into his lap I could see his eyes begin to glaze over and I definitely felt the impression I was making on him!

"Michael honey, would you like to see... my pussy?" I purred at him. 

He gulped looking at me wide-eyed. "Y-yes please," he croaked. He was as nervous as if he was in a whorehouse for the first time!

I smiled at his discomfort and moved back a step to sit on the vanity. I spread my legs and ran my hands up and down the insides of my thighs, adding to his anticipation. I saw his eyes grow wide with wonder at my little show and it encouraged me to play it up all the more. 

At last, my teasing was done and I reached down with one hand and spread my lips apart to show him my wet pink interior. I thought Michael would have a heart attack! His mouth dropped open and his eyes got as big as dinner plates. But what really got me excited was how he was tugging at what looked like a very hard very uncomfortable bulge in his pants!

"Oh my, Michael!" I said, looking at the large prominence in his jeans, licking my lips as I slowly traced the outline with my French-manicured fingernail. "You've got yourself quite a boner there, big brother!"

"Yeah, no thanks to you!" he said, gaining a much-needed ego boost.

"Let me see it!" I said.

"You want to see my cock?" he asked, looking up from his lap at me in surprise at my suggestion.

"Of course! I mean it's only fair - you've seen me now I want to see you!" I said.

"I guess that's true. Okay," he said, and he moved his hands to his belt to begin taking off his pants.

"Wait a second... I want to do it!" I said quickly. I moved down onto my knees in front of him and began working his belt and unfastening his pants. I pulled his jeans off as he lifted up off the toilet a bit to help me. Once his jeans were down and off him, his boxers gave me a better idea of what he kept beneath them. 

"Now the shorts!" I said, and I began easing them down his hips. Then my anticipation and eagerness were rewarded as his cock sprang out when I pulled his underwear down. 

"Oh my God, Michael!" I said as the large, hard and throbbing cock sprang forth ready for action. "You are huge!"

And he was. Michael was twenty-three and he sported a full grown man sized cock. In fact, he was bigger than what I'd seen in my father from the quick accidental glances I'd gotten around the house. I'd caught Dad coming out of the shower or changing clothes a couple times, and accidentally caught a glimpse of his "package" - Michael easily had him beat!

As I knelt there on the bathroom floor, admiring my "big" brother, a very wicked thought came to my dirty mind.

"Michael, would you like me to help you with that?" I asked him softly, hoping that he didn't balk and run off thinking his sister was too wicked to deal with. 

"What do you mean?" he asked.

"Well, you jerk off into your shorts... why not let me help you the same way?" I said.

"You want to jerk me off?!" he asked, incredulously.

"Michael honey, you know that I like sniffing your cummed in shorts. You caught me doing it. Yet you continue to leave them for me in the bathroom when I shower. So you must like that I am turned on by it. Well, this is the same thing. I have gotten you in this... condition, and now I want to help relieve it. Understand?" I explained.

"I guess so... but you can't tell Mom and Dad!" he said.

"Michael, if I told them, I would be in more trouble than you! Remember, I may be the little sister here - but I'm still old enough I should know better!" I said with a smile.

My logic seemed to relax him. He leaned back against the back of the toilet and let me have my way with him. I reached up on the vanity and got the hand lotion, squirting a little into my hand and rubbing it in my hands to warm it up. Then I took his cock in hand and began slowly tugging on it.

I had a boyfriend that let me watch him jerk off once or twice so I knew basically what to do, and Michael was experienced enough that my feeble attempts at it didn't seem to bother him. He began moaning and closed his eyes so he could enjoy my actions better.

I knew my brother didn't currently have a girlfriend. He'd mentioned a couple girl's names in the past, but I don't know how serious he was with any of them. And as for what he had and hadn't done with them, well he was too much of a good guy to kiss and tell and I didn't ask a lot of questions. It wasn't any of my business and frankly, I didn't need the play-by-play!

I could tell by the way he was softly moaning that he liked what I was doing. But the nosy girl in me needed to know for sure. I decided to ask him a little more about his past sex life. "Have you ever had a girl jerk you off like this before?" I asked.

"Noo," he groaned.

"Am I doing it okay? Let me know what you like okay?" I said.

"You're... doing... fine. Oh, that feels good!" he moaned. Michael spread his legs further for me. I cupped his balls with my other hand, softly rolling and massaging them as I tugged him.

It wasn't very long before I could sense his impending orgasm. His breathing had been reduced to a pant and he was moaning and pushing his hips at me.

"Are you going to cum, Michael?" I asked.

"Uh-huh... in a minute..." he said.

"Michael, I want you to cum on me. Please, Michael, I love your cum, please cum on my tits and let me feel your hot cum!" I said.

Michael didn't argue; he didn't even open his eyes. I guess my "dirty talk" was all it took to push him over the edge. Michael let out a groan and let fly. His first spurt hit me square between the tits as I was directly in front of him. I directed his next one towards my left tit and he delivered a spurt right on my nipple. It was so hot and so sexy! It was my right tit's turn next and he covered that nipple just as easily. A couple more spurts and his young nuts were empty. 

I used his still throbbing cock to smear the warm white cum all over my tits and let my nipples feel his hardness before it was gone. Michael watched as I took his cock on a tour of my tits, circling the areola with the tips and then rubbing the very tip across my steel hard nipples.

"Mmm that was very nice, Michael, did you enjoy it too?" I asked.

"Fuck yeah! That was the hottest thing I ever saw!" he said when his breathing slowed enough to talk.

"Well, I think it was pretty hot too... in fact, it made me very horny. Want to watch me get off now?" I said.

"Sure!" he said, sitting up a bit at the idea.

"Let's go into the bedroom, it's more comfortable and I can show you better there," I said. So once Michael gathered up his clothes, we went into my bedroom...
