First time sex between brother and sister.

I was twenty years old and living at home with my parents. My sister (Kelly) who is three years older, left home and got married (to Eddie) at just seventeen. Kelly had a gorgeous little girl called Amy. I often visited my sister on a Saturday afternoon to see my niece, sometimes I’d take her to the park. Occasionally I would babysit for Kelly so they could both go out for the night. I got on well with my brother-in-law; we shared an interest in weight training and motorbikes.

I never got on well with my sister when she lived at home; we fought like cats and dogs. Though I was younger and smaller, being a boy, I was stronger and always beat her in a fight. I always believed the main reason my sister left home and got married so young was to get away from me. I accused her of being our parents favourite because she was older and a girl. She could do no wrong, especially in our father’s eyes. If something got broken or went missing, Kelly would blame me. Our parents would always believe her, regardless of whether I did it or not. I hated my sister so much I refused to attend her wedding, much to the anger of our parents.

I never understood why my bitch of a sister was so popular with boys when we were growing up. From the age of eleven or twelve, Kelly was never without a boyfriend or an admirer knocking at our door asking to see her. The boys were usually a couple of years older. Eddie was her first-ever boyfriend. Strangely she met up with him again after leaving school at just sixteen to go and work in a laundry. At seventeen, Kelly told our parents she was getting married to Eddie and leaving home. Our father flew into a rage stating she was too young and couldn’t marry until she was eighteen without their permission. Our mother managed to calm dad down, saying he risked losing her if he insisted she couldn’t. In another six month’s she would turn eighteen and wouldn’t need permission anyway.

I wouldn’t describe my sister as the prettiest of girls in the looks department, but maybe that’s because a boy isn’t supposed to fancy his sister. However, Kelly was a very early developer and always did have a very nice body, which I suspect is what made her so popular with boys. I remember when I was just nine or ten, I walked in on my sister taking a bath and got a good look at her large breasts. Kelly screamed at me to get out, and shortly after, dad fitted a lock to the bathroom door at our mother’s insistence. After that, I would force my way into Kelly’s bedroom at every opportunity to try and catch her naked or partly dressed. My sister always took pride in her appearance and nearly always wore pleated skirts and silky blouses or pretty dresses. She was the only girl in school that wore a white satin blouse as part of her uniform. This might sound strange, but I was always envious of the nice clothes she wore, especially her shiny satin blouses. I especially remember, Kelly was twelve (almost thirteen) and had just started senior school; mum bought Kelly her first satin waist-slip with pretty lace around the hem, to wear under her school skirt. My mother once caught me masturbating in the bathroom after taking Kelly’s white satin school blouse and waist-slip out of the laundry basket to try on. I often wished I had been her little sister so I could have worn her cast-offs. Perhaps if we had been sister’s we would have been much closer when growing up.

—————————————————–

This particular and memorable Saturday afternoon, I visited my sister like I often did. I rang the doorbell and was surprised by the speed at which Kelly answered. Almost as if she had been standing there waiting for me. I was more surprised when the door opened and saw my sister dressed in a very slinky and clingy black satin full-slip. It had pretty scalloped lace trim around the bust and hem and delicate thin shoestring straps. I gasped with delight as I looked Kelly up and down and admired her lovely satin slip. I prayed that Kelly hadn’t noticed my reaction. I was somewhat relieved when she just turned away and picked up a paintbrush, then started painting the hallway.

“Oh!… That’s why you answered so quickly,” I said as I entered, watching her as she continued painting dressed in only her lovely black satin full-slip.

“Amy isn’t here,” she replied. “Eddie has taken her to visit his mum for a few hours. They haven’t been gone long, so won’t be back for some time yet.”

At that moment, I couldn’t believe how sexy my sister looked. Confused thoughts ran through my head as I watched Kelly intensely. I loved the way the slinky material of her satin-slip rippled when she moved and the way it shimmered as it caught the light shining in through the window. I was becoming aroused and having inappropriate thoughts about my sister. With each second that passed, I became more aroused and the more attractive she looked to me. Her long brown hair cascaded down her back; her ample breasts filled the cups of her silky-slip; her nipples pressed against the slinky fabric; the outline of her panties showing underneath as the clingy slip caressed every curve of her shapely body. I was aware my breathing grew heavier as I became more aroused. I tried to remain calm so as not to draw attention to myself.

“Why are you painting dressed like that?” I asked.

“I didn’t want to ruin my clothes,” replied Kelly.

“But you will ruin your lovely slip,” I told her. She glanced across at me and chuckled.

“What this old thing?… It’s just a slip. I’ve got plenty more,” she said.

Her words, “I’ve got plenty more,” echoed in my head, over and over. I was excited about babysitting for Kelly again. I knew I would be sneaking into my sister’s bedroom to look through her clothes, to find those lovely slips she just told me she had.

“It’s not just a slip, it’s satin and it’s lovely,” I told my sister.

She laughed. “Are you feeling okay?… So you like my slip do you?… as I said, it’s old and I’ve got others, some much nicer than this one,” said Kelly, amused by my behaviour.

“It may be old, but it’s much too nice to ruin by getting paint on it,” I insisted. “And you look gorgeous in it too.” Kelly looked at me in disbelief at what she was hearing.

“Have you been taking drugs or something?… Since when did you ever say anything nice to me?” she asked.

“That’s because I’ve never seen you in just your slip before,” I replied. Kelly paused from her painting momentarily to think.

She looked down at her satin-slip, then asked, “So what is your fascination with satin?… I never understood why you liked it so much. It’s just a piece of material.”

“Just a piece of material?… It’s so much more than that. It’s so elegant and sensual, the way it ripples as you move and the way it shimmers in the light. There is nothing so attractive as a woman wearing satin. It can even transform a plain-Jane, that nobody would normally look twice at into a stunningly sexy woman that people can’t take their eyes off,” I said. Kelly listened to me with extreme interest and disbelief at my comments.

She laughed. “Wow!… listen to you, Mr philosopher. There’s more to you than meets the eye,” said Kelly sarcastically.

“Okay then! You said you got lots more, so tell me why you wear satin-slips?” I asked.

“Because they stop static electricity building up and stop my dress or skirt clinging to my legs, and they can also stop some clothes making you itch,” she replied very unconvincingly.

“If that’s the case, why do they have to be so sexy, with all that pretty lace trim?… And what about camisoles and teddies and French knickers?… Why do they all have to be so pretty when they are underneath a woman’s outer clothes? No one gets to see them anyway. And why are they made from silk and satin and lace?… And why is it only women get to wear them when a man’s underwear is so dull, boring and practical?…”

“I don’t know. I hadn’t thought about it. I can’t answer that!” replied my sister. ”

So what about your knickers?… Are they satin too?” I asked my sister.

“Yes, my knickers are satin. All my underwear is silk or satin. I can’t believe we are having this conversation. Why am I standing here with my brother talking about lingerie and my choice of underwear?” said Kelly.

“I’m just interested in why you wear satin underwear when you don’t wear satin blouses anymore? I’ve not seen you wear a satin blouse since you left school,” I asked.

“I suppose most women wear satin lingerie because it feels nice next to their skin and makes them feel sexy and feminine,” said Kelly rather meekly and embarrassed. “And for your information, I do still have several satin blouses and a couple of satin dresses too, but they are too dressy, so I only wear them on special occasions.”

“Ah-huh!… I knew it; you wear satin because it feels nice. You admit satin feels nice and makes you feel sexy,” I said.

“Yes… Yes it does,” replied Kelly, as she picked up her paintbrush and continued with her painting.

“So do you feel sexy now wearing that lovely satin-slip?… And would you normally open the front door in just your slip?” I asked curiously.

“I guessed it was you. You normally come round on a Saturday afternoon,” replied Kelly.

“You would have had a huge shock if it had been some stranger at the door. Or maybe that would have given you a thrill, eh?” I suggested.

“Don’t be daft,” said Kelly, blushing.

As I stood watching my sister painting in her lovely black satin-slip, I grew more aroused. My cock was getting hard with incestuous thoughts running amok in my head. I moved closer behind Kelly, placing my hands on my sister’s tiny waist, caressing that lovely black satin material.

“What are you doing?” asked my sister.

“I just want to see what it feels like,” I replied.

“What?” she asked.

“I was just wondering what your slip feels like,” I said, as I continued to rub my hands up and down her slinky satin-slip. I was somewhat surprised that Kelly didn’t try and stop me or object. I moved to her side so I could watch her as I moved my right hand down over her bum and stroked the lovely satin-slip, feeling it slide effortlessly over her silky satin knickers. My left hand slid up and down her stomach with my thumb just brushing the underside of her shapely and firm breasts. My sister stood motionless, looking me in the eyes, biting her bottom lip, her right arm outstretched with the paintbrush touching the wall but not moving.

“So you didn’t answer my question,” I said.

“What question?” asked Kelly with a slight quiver in her voice.

“Do you feel sexy now, wearing that lovely silky slip?”

Kelly looked me straight in the eyes. Without even blinking, she answered, “Yes, I do.”

“I love the way your slip feels over your satin knickers,” I told my sister as I continued to feel her buttocks. “Think how nice a satin blouse or a satin dress would be over the top of your slip, satin upon satin. You would feel the layers of satin sliding over each other as you moved.

Imagine the admiring looks you would get from people if you wore a satin dress to go grocery shopping,” I said. Kelly laughed at the idea. “I’m serious. You have no idea how much attention you would attract from men and other women. You should wear satin every day, even if just a simple shirt-style satin blouse with a pair of denim jeans. Maybe a pencil skirt with a long slit at the rear, with your satin-slip showing underneath as you walk along the road.” Kelly chuckled once more.

“Are you serious?…. Are you telling me you notice such things as a woman’s slip under her skirt when she walks?” asked Kelly.

“Hey sis, I can spot a woman wearing satin from half a mile away, even if it’s just the collar of her blouse peeking from beneath her coat. It drives me crazy. Honestly!” I told her seriously.

As I continued to fondle my sister’s buttocks with my right hand, I moved my left hand higher over her breasts, gently brushing over her nipples as I did so. Kelly took a deep breath as my hand glided over her breasts and brushed her sensitive nipples. She closed her eyes and tilted her head back slightly, letting out a gentle sigh as I continued to feel her tits through her satin-slip. I cupped my hand over each breast in turn and gave it a gentle squeeze. My sister’s tits were amazing, perfectly formed and very firm, despite having given birth to Amy. Kelly made no attempt to stop me playing with her tits, the pleasure she was getting from it was obvious. Her nipples grew hard and protruded further out through the thin slinky material of her satin-slip. I pinched each nipple through her slip and gave it a tweak. I moved back around behind her, fondling my sister’s breasts with one hand, whilst sliding the other hand down her body and between her legs. My right hand continued to squeeze and fondle Kelly’s tits whilst my left hand cupped her pussy. I rubbed my left hand up and down Kelly’s silky slip between her legs, feeling the satin-slip slide over her satin panties. Kelly dropped the paintbrush. Her body went limp like a rag-doll, her legs buckling beneath her. If I hadn’t held her up, she would have collapsed onto the floor. Kelly made audible moans of pleasure as I tweaked her nipples and rubbed her slip over her pussy. The pleasure she was getting was obvious and she made no attempt to stop me. I was determined to see how far Kelly would let me go before stopping me or saying no.

“You said Eddie wouldn’t be back for a while?” I asked.

“Not for… at least… two… maybe… three hours,” replied Kelly, panting with deep breathes.

I picked up my sister’s limp body in my arms and carried her into the lounge, placing her on the sofa on her back. As she lay there looking more attractive than ever in that lovely black satin slip, Kelly surprised me by pulling her slip up around her waist to expose her bright red satin panties, as if she was inviting me to explore.

“Oh wow!…” I exclaimed.

I noticed a small damp patch and could make out the slit of my sister’s pussy through the tight silky material. I spread my sister’s legs wide apart and knelt on the floor in-between. I placed the tip of my index finger on my sister’s silky soft satin knickers and rubbed it up and down her slit. Kelly immediately shut her eyes and let out a gentle moan, taking deep breaths. Her breasts were heaving. Watching my sister as I stimulated her pussy turned me on. The tight satin material felt great against my cheeks as I rubbed my face over my sister’s soft silky panties. I pushed my nose into the damp patch and rubbed it up and down her pussy slit. The pungent smell hit me like a slap in the face, but being aroused at what I was doing to my sister, I didn’t care.

“Oh, fuck!…. I can’t believe this is happening,” moaned Kelly.

I couldn’t believe it was happening either, but until my sister said no or tried to stop me, I wasn’t about to stop. Kelly was writhing on the sofa, squeezing her own tits through her satin slip. I hooked two fingers under Kelly’s satin panties and pulled them to one side. I was somewhat surprised that my sister was completely shaven and admired her moist pussy slit. It wasn’t at all how I expected it to look. A friend told me he didn’t like going down on his girlfriend. He said it looked like a bomb had gone off down there. I remember thinking to myself, “What a crude description!” Having seen pictures in magazines, I understood what he meant. In comparison, my sister’s pussy was one of the nicest I had seen. Having sucked my fingers to wet them, I explored my sister’s pussy more closely.

I buried my face between her legs and pushed my tongue as deep as I could into my sister’s snatch, licking and sucking as vigorously as I could. I flicked Kelly’s clitoris with my tongue, sucking it hard, making her scream with pleasure, her whole body writhing about and shuddering as she orgasmed.

I was so aroused my cock was rock hard and twitching in my pants. I just had to relieve myself somehow. Either my sister would have to let me fuck her, or I was about to rape her. I pushed off my shoes, then stood up and quickly removed my jeans and pants whilst Kelly just lay back on the sofa and watched with a shocked look on her face. I stood there momentarily in just my shirt, with my eight-inch erection, waiting for some glimmer of response from my sister. Kelly stared at my cock with a slightly worried look, knowing what was about to happen. Unsure if she should try or even wanted to stop me. I reached down and removed those gorgeous bright red satin panties Kelly was wearing, then lifted them to my face to sniff them. After discarding the panties, I grabbed Kelly by her ankles and pulled her onto the lounge floor onto her back. Kelly hit the floor with a thud, banging her head.

“Ouch!… Careful!” cried Kelly, rubbing the back of her head.

I knelt on the floor and spread her legs open, placing them over my shoulders, pushing all my body weight down onto her. My erect cock found the opening of my sister’s sopping wet pussy without any need to guide it into position. Within seconds I was buried deep within my own sister’s pussy and thrusting my cock in and out as hard and as fast as I could, giving it the pounding of her life. My only consideration at that moment was for my own selfish pleasure. I couldn’t have cared less if I hurt my sister or not, as I pounded her pussy with all my might. I began to sweat heavily. My shirt clung to my damp body; drips fell from my forehead onto my sister’s face as I looked down on her. I pumped my cock in and out continuously, watching her breasts bounce back and forth under that rippling black satin slip. Kelly screamed with each inward stroke of my cock. Her face contorted as if in pain.

“Don’t cum inside me!… Don’t cum inside me!… Please don’t cum inside me!” she begged, over and over.

I ignored my sister’s pleas. I had no intention of withdrawing from my sister’s pussy until I had discharged my load of cum. Suddenly, my whole body shook. An intense feeling I can only describe as a-mild-electric-shock ran through my hips and thighs. I grunted and pushed my cock deep inside my sister’s cunt, as I ejaculated inside of her, filling her womb with my fertile sperm.

As I got dressed, Kelly lay on the floor in the lounge and started to cry. “Oh my God!… Oh my God!… Oh my God!” she said over and over. “What the hell have we done?”

A sudden rush of guilt hit me. I felt totally ashamed of myself. I sat down on the sofa and stared at my sister, still crying on the floor. I started to tremble uncontrollably. Panic was setting in at the realisation of what I had just done. Neither of us spoke for what seemed like an eternity. After probably just a few minutes, my sister got up off the floor.

“I’m going for a bath,” she said in a soft, hardly audible tone. I sat there gathering my thoughts, trying to fathom what had just happened and why? After about thirty minutes, my sister reappeared dressed in jogging pants and a baggy sweatshirt. She had made us both coffee and handed me a mug.

“Thanks!” I said, watching her as she sat down opposite in an armchair. She sat staring at the floor, avoiding any eye contact with me. Nothing was said as I sat drinking my coffee. I kept looking at my sister, wanting to do or say something to put things right, but she remained staring at the floor the whole time, deep in thought, avoiding any eye contact.

Eddie was due back with Amy soon. I didn’t want to be around when they arrived home. I stood up and said goodbye to my sister, but she didn’t reply. Her red satin panties were still on the lounge floor exactly where I had discarded them. Imagine Eddie arriving home with Amy, walking into the lounge, seeing Kelly’s red satin panties on the floor in the middle of the room. Why?… How would she explain that?… I picked them up, watching my sister. She didn’t move or take any notice as if she were in a trance. I put the red satin panties in my pocket and left the room.

I went upstairs to the bathroom before I left to use the toilet. My sister’s lovely black satin-slip was lying on the bathroom floor next to the bath. I picked it up and looked at it, holding it up to my face and smelling it. I could smell my sister’s perfume on her lovely slip. I folded it neatly into a small bundle and took it with me.

As I exited the bathroom, I stood at the top of the stairs looking towards my sister’s bedroom. My thoughts momentarily drifted to those satin-slips Kelly had admitted to owning, and the satin blouses and dresses too. Did I dare take a quick peek through her wardrobe? As I pondered whether I would get caught, the reality of what I had just done with my sister dawned on me. The immense feelings of shame and guilt came flooding back.

I went back downstairs to the lounge. Kelly was still sitting staring at the floor, her coffee which was now cold, still in her hand, not having moved an inch.

“I’m going now,” I told my sister. She didn’t reply.
