The first story in my Satin Sister Series. My sister gives me my first blow job.

My First Blow Job.

My sister (Kelly) and I never got on well as kids, we were always arguing and fighting about something. Even though I was 3 years younger than Kelly, being a boy, I was stronger and always got the better of her in a fight.

My sister was in her last year at school as a senior, this meant she no longer had to wear a uniform. All sixth-formers were allowed to wear whatever they wanted within reason, as long as they were smart and presentable and didn't give the school a bad reputation. Since turning 17, Kelly had started taking more pride in her appearance, dressing more elegantly and ladylike. Gone were the jeans, t-shirts and baggy sweaters, instead she wore dresses, or a skirt with a nice blouse. My sister had always been naturally very pretty, and popular with boys, regardless of what she wore. Recently she had started wearing make-up, which made her look older and even more attractive. All my friends fancied her, even I started to lust after her, not that I would have ever admitted it to anyone.

Pretty satin underwear had started to appear in the laundry basket. At first, just bras and panties, but as time went by, satin camisoles and lovely waist slips started to appear. I knew the silky lingerie had to belong to my sister, mum never wore anything like that. Whenever I got the chance, I would sneak into my sister's bedroom and look through her underwear draw.

I usually arrived home from school about thirty minutes before Kelly. Mum and dad would normally get home from work about thirty minutes after that. One day I was in the lounge watching television, when Kelly arrived home from school. She removed her coat and deliberately threw it down on the sofa next to me, to annoy me.

"Oh wow!" I said out loud unintentionally, as I admired the long sleeves and open necked collar of her shiny silver satin blouse, which she wore under a black V-neck tank top. Kelly turned and look at me.

"What's the matter with you?" she asked nastily. I just sat in silence staring at my sister in her lovely satin blouse. That was the first I had seen Kelly wear a satin blouse. I had never told anyone about my satin fetish. Kelly had no idea the effect her blouse was having on me. My cock grew hard as I became aroused. I shifted around in my chair to hide the growing bulge in my trousers.

"What the hell are you staring at, you little creep?" she asked getting annoyed, as she looked down at herself puzzled. I sat mesmerised as if hypnotised or drugged, just admiring the lovely view of my pretty sister wearing shiny shimmering satin.

Without thinking I blurted out, "Wow!... She is gorgeous, I would definately tap that, given the chance." As soon as I said it, I was jolted back to reality, by the shock of what I had just said out loud, in front of my own sister.

Kelly gasped and stepped back with shock. "What did you just say?"

"Oh shit!" I exclaimed. I stood up and ran out of the lounge, up to my room, feeling very embarrassment. Shortly after, there was a knock at my bedroom door and my sister called out to me, the tone of her voice was different from usual. Instead of the harsh abrupt insulting tone, I heard a soft sweet feminine voice who beckoned me to open the door. I knew I couldn't hide forever, so I hesitantly opened my bedroom door to see Kelly smiling sweetly. This put me at ease slightly.

"Can I come in please?" asked Kelly, in a calm polite manner. I opened the door wider to allow her to enter my room. Kelly sat on my bed and beckoned me to sit next to her, so I did.

"It was a huge shock to hear you say what you did. I don't want you to be embarrassed about it, I'm not going to tell anyone. It was kind of flattering, especially coming from my little brother. I just wanted to know what made you say such a thing?" asked Kelly. I just stared down at the floor, feeling really foolish and embarrassed, not knowing how to justify what I had said to my sister. "Will you talk to me please?" said Kelly, putting her arm round me to try and comfort me.

Hearing my sister say 'please' (twice) was a shock in itself, I had never heard Kelly say please to anyone; but having her put her arm around me, was unheard of. I looked down at the hem of Kelly's black pleated skirt, which had risen up slightly when she had sat down on my bed, and noticed the lace hem of her red satin slip showing.

"Oh, wow!.... that's nice!" I said in a soft whisper, as my heart pounded and my cock grew hard once more.

"What is?... What's nice?.... My skirt?" asked Kelly, looking down puzzled.

"No!... Your slip is showing," I told her. Kelly looked down at the hem of her skirt and saw a hint of red lace showing, but instead of pushing her skirt down, she pulled the skirt up higher to reveal her shimmering red satin slip with two inches of scalloped lace around the bottom.

"OMG!.... That's lovely," I said, unable to conceal my excitement.

"So you like my slip?......That's why you were staring at me downstairs, because my slip was showing?..... Does my slip turn you on?" she asked. Suddenly nothing seemed to matter any more, my nerves were gone and I wanted my sister to know how much I fancied her.

"No Kelly, I was staring at your lovely satin blouse. You are so pretty and you look even prettier in that satin blouse. I've never seen you wear a satin blouse before, and now you just showed me your lovely red satin slip too."

Kelly sat thinking for a moment. "So it's satin that you like?" she asked. I nodded timidly. "I had no idea," she said. "So do you really think I'm pretty?"

"Kelly....... I think you are the prettiest girl I know, maybe even the prettiest girl I've ever seen," I told her. Kelly blushed slightly, then stood up and went to her own room.

As I sat on my bed, thinking about how lovely Kelly looked in her satin blouse, she reappeared in my doorway once more. My jaw dropped and I sat staring open mouthed at Kelly.

She laughed at my reaction and asked, "So how do I look now?" Kelly had removed her black tank top and her black pleated skirt. I couldn't believe my sister wasn't embarrassed to let me see her in her slip.

"Wow! You look amazing," I told her. I couldn't believe I was actually being nice to my sister and paying her compliments. She was making me aroused, as she playfully pranced around my room.

"Oh My God!.... I guess you weren't joking," she said pointing to my bulge.

"GET OUT, GET OUT" I shouted. I was so embarrassed, I didn't want my sister to see me with an erection.

"It's okay, really it is. I'm really flattered that I turn you on. Actually you've helped me understand why the boys at school have been hanging around me all day," said Kelly.

"Boys always hang around you. You attract them like flies around shit," I said rather crudely.

"Well, thanks for that comparison," she replied sarcastically. "Seriously though, the boys at school have been flirting with me all day, now I know why. I had no idea wearing a satin blouse would have such an effect on boys."

"Can I touch it?" I asked.


"Can I touch your blouse. I want to see what it feels like?" I asked again.

"Sure go ahead," said my sister. I placed my hand on Kelly's arm and rubbed it up and down her silky sleeve.

"Can I hug you?" I whispered timidly.

"You want to hug me?" she replied, shocked at my request. "Okay, I suppose so."

I put my arms around my sister, gave her a big squeeze, and rubbed my hands all over her satin blouse. I could feel my sister's breasts pressing into my chest. The feeling was incredible.

"What does it feel like to wear satin?" I asked.

"I hadn't really thought about it," she replied. "But it actually feels kinda nice, now that you ask," said Kelly.

"I love the way your nipples poke out through your blouse," I said brazenly. Now it was my sister's turn to feel embarrassed. "Can I touch them?" I asked. I figured my sister would probably say no, but I had nothing to lose by asking. Kelly looked at me very straight faced and serious. She looked at the clock to check the time, our parents were due home soon. I knew the very instant she looked at the clock, she wasn't going to say no. She swallowed, then coughed to clear the lump in her throat.

"Okay!" came the simple reply, in a nervous faint whisper.

I placed both hands over my sister's breasts and began to fondle them gently through her lovely satin blouse. It was like a dream. If I had died and gone to heaven, then this is what I imagined heaven to be like. Not only was I getting my first feel of a girl's breast's, but they were my own sister's breast's, and a nice size too.

"OMG!.... They feel amazing," I told her. "How come you aren't wearing a bra today?" I asked.

"I don't always wear a bra, unless I've got PE. Anyway, I'm wearing a full-slip with cups," she explained.

"Does your slip have lace around the top as well?" I asked, already knowing the answer; I could see the outline of lace through her thin satin blouse.

"Would you like to see?" she asked. Not bothering to wait for an answer, Kelly surprised me by unbuttoning her blouse. The whole time my sister never took her eyes off my raging hard cock trying to burst out of my trousers. Kelly licked her lips several times before making eye contact with me and blushing bright red.

"Oh My God, Oh My God, Oh My God, Oh My God!" I said over and over, breathing heavily and unable to conceal my excitement.

I couldn't believe my sister was standing in my bedroom, in front of me, with her blouse completely unbuttoned and her slip on show. Her breasts looked absolutely amazing, trying to burst out of her tight figure hugging red satin slip.

"So did you really mean what you said when we were downstairs? she asked.

"What did I say?" I asked, not sure what she was referring to.

"You know.... Erm..... That you..... Errr.... What you said you wanted to do to me?"

"What I wanted to do to you?" I replied, shaking my head confused.

"You said you wanted to fuck me?" Kelly blurted out, looking away and breaking eye contact.

"Nooo!.... What I said was, 'I would definately tap that, given the chance'."

"Same difference," replied Kelly.

"Well, maybe if you weren't my sister, perhaps I would," I said.

"Hmm....." said Kelly, staring at my cock. "I suppose you'll go and jerk off into a tissue when I leave," she asked.

"Yeah I suppose," I replied, nodding.

"I was just thinking, it would be a shame to let that go to waste," she said.

"What do you mean, let it go to waste?" I asked.

"I could always give you a hand with that," she said, placing her hand on my crotch and giving it a gentle rub.

"Are you serious?" I asked, thinking my sister was offering to give me a hand job. There was no way on earth, I was about to miss out on a hand job from my own sister. It was my turn to glance across at the clock. "You'll have to be quick," I said. Mum and dad will be home soon.

In a second Kelly was on her knees. She wasted no time in undoing my trousers and pulling them down to the floor. She looked up at me completely bewildered.

"What's wrong?" I asked.

"Are those my panties you're wearing?" she asked.

Suddenly, I just wanted the ground to open up and swallow me. I had completely forgotten, I had taken a pair of my sister's dirty red satin panties from the laundry basket and worn them to school.

"I'm so sorry," I replied, shaking nervously.

"You are full of surprises today aren't you?" she said, not seeming the slightest bit angry. In a moment, she had my penis out and was stroking it back and forth with her hand. The feeling was intense, like nothing I could ever experience with my own hand.

"We need a tissue," I said. "I'm gonna cum any second now."

"No we don't," she replied.

My sister placed her mouth over the end of my cock and started to suck with such enthusiasm. I couldn't believe it was happening. Never in a million years did I expect my sister to give me head. Kelly began sucking vigorously on my cock, her head bobbing back and forth as she took the whole length of my cock into her mouth. I wondered if she knew this was the first time I had ever had my cocked sucked.

I tried desperately to pull my cock out of my sister's mouth. "I'm about to cum, I'm gonna shoot my load," I yelled. My sister was having none of it. She put her arm around the back of my legs and hugged me tightly as she kept sucking on my cock with such enthusiasm. I tried desperately not to cum in my sister's mouth.

I couldn't hold out much longer, I was at bursting point. "Kelly, I'm gonna cum," I warned her again as I tried to pull away. My sister would not let me go. She hugged me tight as she kept sucking on my cock, her head bobbing back and forth, one hand gently cupping my balls. Then I shot my load of spunk deep into my sister's mouth, spurt after spurt. My body shuddered involuntarily, like a mild electric shock had shot through the tops of my thighs. "Oh Fuck!.... Oh God.... I'm sorry.... I'm so sorry," I said to Kelly. Kelly continued to suck on my cock even after I had shot my load of cum into her mouth and my erection began to subside.

"What have you got to be sorry about little brother?" she said standing up, grinning like a Cheshire cat. "That was fun."

The front door slammed and mum called out, "Kelly, Steve, I'm home."

"Hi mum, we're both upstairs," called out Kelly as she buttoned her satin blouse and left my room.
