My phone vibrated along with the sound of the tone to argue a message had been received. I was nearing the end of the biz on my PlayStation in my room as I glanced at the phone to see my sister's name as the sender so decided to finish the conclusion 90 s of play guessing that she was only abusing me in some way or was sending me a suspect picture she had found on the net.
As the hold out few seconds counted down my speech sound went again indicating a second subject matter from her too.

I congratulated myself on my win and exchanged the restrainer in my hand for the earpiece on the bed beside me.

I swiped the screen apprisal with my thumb to spread out Chrissie's substance and sat gawping at the motion picture that met my gaze.

I stared at the screen which was filled with a selfie picture of my sister in her underclothes wondering why the hell she had sent it to me. Despite her face not showing, I obviously recognised her bed, not to advert a familiar knapsack in the background signal so it was definitely her. I tapped on the next message and was met with another similar pic, only this sentence she had laid on the bed reach over her shoulder joint to take a picture of her bum showing her thong disappearing between her sweet-scented stern cheek !

It occurred to me that she had More than likely sent them to me in mistake but I wasn't going to complain.

I started to type my reply ;"Very nice sis, but I'm pretty sure you've just sent them to me by mistake - and btw, who said u could borrow my Nike rucksack ?"

I hit ‘ send ’.

I laughed out loud and imagined the feel on her face when she realised she had sent the pics to me in wrongdoing and would no doubt be banging on my door shortly begging for me to delete them.

I brought the ikon back up on silver screen to admire the view, despite them being of my own sister. But there no denying she was hot, as all my mates would point out on how salutary it must be to have such a ‘ babe'as an sure-enough Sister living under the Saame roof. Of course I just shrugged it off, but without doubt it was certainly pretty damn good being her comrade. We had always got on well together, having the usual sibling rivalry that kids do, but being nearly 3 twelvemonth older than me she always went into ‘ protective'mode when she needed to, which was possibly even stronger now she was 21.

Not that seeing my baby in underwear should really shock me because I was used to her, and mum too come to think about it, walking around the odd clip in their knickers and bra, although the last few calendar month they had seemed to cover up to a greater extent as they saw me maturing quickly myself. Chrissie would even tease me now and then when certain things popped up in conversation, but nothing malicious. Being an athletic house we were all quite fit and active causing the odd joke now and then as both mum and Chrissie always said they had the unfortunate affair of having big bosom. That was always met by dad's reaction of saying it was definitely no big problem and one that I had started to check with.

"But you don't have these things bouncing around while you exercise !"mum would say cupping both breast in her hands and giving them a squeeze.

Dad would then move around behind her and arrive at round of drinks to cup them himself saying ;"here, let me hold them for you then whilst you do it !"before mum slapped his hired hand away and laughed.

My telephone suddenly buzzed as Chrissie replied.

"whoreson bro, u got me ! Obv my error cos they should hold gone to Shaun so how about u just delete them as if they never happened ? Xx"

So they were meant for her new boyfriend like I thought making me grateful for once that she had picked mortal with a name starting with my initial, meaning I at least got to see them even if it was by mistake.

"No probs, I'll delete them I promise but should u really be sending them to mortal u hardly hump ?"I asked, sending my reply.

My screen lit up again ;"Thanks for the advice Steven, but I made sure my face wasn't showing just in case ! Xx"

I tapped away ;"Yeah, but it's obviously u so just be careful as no question the jerk will shew his mates anyway !"

"Eww, surely he'll keep those just for himself ? Xx"Chrissie replied.

"U r joking ? He'll bragging about u as much as he can because you're so hot !"I sent back.

There was a few arcminute before she replied making me wonder if she was having a think about what I had put.

"Thanks for the compliment - I think ! But at least I didn't appearance him too a great deal material body ! Xx"

"Which is a damn pity seeing's how I got them in error !"I replied.

dickhead ! Did I just admit to my baby that I wished I had seen her with less on than she already had ? I sat for a few minutes and thought about how I could apologise without sounding like some pervy stalker now !

But my phone pinged again before I had chance to respond with a content from her ;
"You mean like this ? Xx"she put, and sent a picture of her laid on her back with her impart knocker exposed !

Holy roll in the hay ! Had she really just done that ? As much as I didn't want to, I got hard.

"dickhead Chrissie, that's exactly what I meant - please secern me u oasis't sent that to him ?"

I looked at the exposure again whilst waiting for her reaction and my god did it look good. I even zoomed in to see the grand nipple finding myself even admiring the esthetic flavour of the picture from how the brightness level hit her body. Her delectable looking slopped dead body offset with pinko decoration and blonde hair. I found I was aching now in my groin as my stopcock pressed against my jeans.

"No Steven, don't panic, that was just for u for your variety fear and in fact I haven't sent any ! Xx"was her reply.

sanctum fuck ! My own sister had sent me a pic of her own boob knowing full well it was for a goody to her small pal. I was already wondering how I could hide that picture away knowing it would probably gift me decent wanking ammunition for the next 50 yr !

"So are u going to blue-pencil that one ? Xx"she asked as if reading my mind.

"Of track - but perhaps in a few minute of arc !"I said.

"Lol, pervert ! Xx"she replied.

"Whoa, u started it !"I sent back.

"True, and perhaps not a well example to set ? Xx"she said.

"Sod the object lesson, but what a perfect boob !"I replied.

"Thanks xx"came back.

"It matches the perfect bum"I said.

"U recall ? Xx"she replied.

"shit, deffo sis, u must surely know that ?"

"Nice to be appreciated though xx"Chrissie said.

"Believe me, I appreciate you very much right now !"I said.

"LOL xx"came back.

I stared at the picture again, wondering just how soft it would sense to receive my helping hand on it.

I have always been a bit of a joker so on a whim decided to strip to my boxers and take a characterisation of my bum which I sent to Chrissie with the text ;"2 can play that plot !"

It was a pretty lame picture and one that wasn't too risqué in any way to be too embarrassing, just funny.

Chrissie replied ;"Haha, Touche ! But what, no flesh ? xx"

I felt my eyebrows rise as I pondered the interrogative. So obviously I took a picture of my own bare chest and sent it !

I could hardly conceive I was having this weird ‘ texting'conversation with my sister, or should that be ‘ sexting'? The fact I was now standing in my sleeping accommodation in just my boxers with an hard-on pushing against the front led me to believe that perhaps I was in fact ‘ sexting'with my sister !

"LOL, OK, you got me Steven, very funny as I was worried your pic might let been down in the mouth ! Xx"

I was shocked."You wanted lower berth ?"I sent.

Chrissie replied ;"No, not wanted, but knowing your sense of sense of humor wondered whether you would have sent one ! Xx"

I smiled, then replied feeling brave ;"Teehee, the screen wouldn't have been big enough lol !"

"STEVEN ! stopover bragging ! Xx"was sent back.

"Only joking !"I replied quickly.

"Perhaps I should be the judge of that ? Xx"Chrissie replied.

Shit, she had shocked me again. Was she secretly hoping I would have sent a pic of my own dick ? I considered having a quick search on the net for a pic of a immense knob to place but instead found one of a cockerel shuttle, which obviously most multitude just call a cock, and sent that.

I think I laughed out loud as I imagined her opening the picture.

Whilst I was waiting for a response, I had another smell at the pictures of Chrissie which only caused me to languish more in my groin with my raging hard-on.

Suddenly there was a tap on my room access which was then opened before I had opportunity to shout either ‘ come in'or ‘ hold on'and Chrissie appeared, in her underwear, albeit with her bra back in its correct position, closing the door behind her.

"Very amusing !"she said, holding her phone up with the moving-picture show of the skirt on.

"CHRISSIE !"I called, grabbing a pillow and covering my front.

But not before she obviously saw the tent !

"Oh ! Sorry !"she said, looking genuinely embarrassed.

And genuinely hot !

I looked on and took in every detail whilst I had the chance in the few sec I thought I would get before she disappeared again, but instead, she just stood there.

"I didn't mean value to…."She started to say,"I mean, I didn't think I…."

"Would have that effect on me ?"I finished.

"Yeah, something like that !"she said.

I gave her my best ‘ WTF'look and said,"Derrr, what effect did you conceive your amazing body would give birth on me ?"

"But I'm your baby !"she said as if stating the obvious.

"And ?"I asked.

"And I perhaps should have known better !"she answered, now understanding properly."Come on then, seeing as I'm here, let's have a look !"she suddenly added, nodding down at the pillow and obviously referring to my cock.

"No way !"I spat out.

She took a footmark forward and made a playful grab for the pillow.

"Chrissie, get off !"I said trying to duck her grasp. Her tits bounced seductively as she reached forward which made for a lovely eyeshot despite the fact I was trying to get out of her way.

"seed on little brother, let's see the damage !"she said, making for another grab at my pillow.

Her wonderful perfumed smell met my nostril adding to the sight of her tight consistence causing my sentiency to go into overload, but I was still witting I didn't want to show off my nude penis !

I tried to dodge her again but she easily grabbed the edge of the pillow and yanked it voiceless causing me to fascinate the other end as if now having a tug-of-war contender. But she was pretty strong and as a great deal as I tried to keep it in front of my fork, it was now waist top leaving me more exposed in my packer. I let go of the pillow which she immediately used to hit me with like we used to do when we had a rest scrap causing me to lose my balance and fall on the bed.

Chrissie just laughed making me pleased mum & dad were out or they would have probably come up to see what the battering and haphazardness was.

She looked down at me, her eyes appraising my eubstance as if impressed that her little comrade was growing fast. Then she tossed the pillow at my brass which I used both handwriting to champion myself with by catching it, giving her a s recreation which she used to straddle me, grabbing both of my wrists and pushing down onto the bed above my head.

I struggled slightly, but not quite as much as I could have, and as the commotion subsided we found ourselves in a fellow berth we have been in probably hundreds of times over the years, with one of us straddling the other holding their arms down by the wrists, but none of them recently. And I think we both knew instantly why that was.

With her tits literally inches from my boldness, Chrissie sat back slightly releasing some of the pressure on my wrists, but as she did so her arse perched nicely onto my groin as I felt my erection nestle somewhere between her cheeks ! I also knew instantly that with the minutes wrestling we had done, my prick had come through the fly-hole at the front end of my drawers as I felt ‘ skin on hide ’.

She looked down at me."Is that ?"she asked, wiggling her bum.

I stared straight in her eyes and nodded.

"Shit, sorry bro, I was only having a laugh !"she said.

Her chest of drawers heaved and her wondrous globes glistened with a speck of sweat.

I felt a twinge in my rooster as yet more pedigree rushed to it making it as stiff as I think I have ever known.

"I'll tight my eyes when I get off if you want ?"she said as if that would make me palpate better.

I just shrugged as I'm not sure it would be any lupus erythematosus block now. But she then moved again, her bum cheeks rubbing me and for a second I honestly thought I was going to cum !

"You OK Steven ?"she asked, suddenly cognisant of the concentrated look on my face.

I nodded, but I think she clocked the reason."Do you want me to sit still for a minute ?"she asked.

"Mmm, please"I just about managed to say, trying to think of anything to cool me down.

My only saving grace, or so I thought, was the fact my erection was pointing up the back of her crack cocaine rather than against my eubstance under her cunt or I think I would birth spunked my load by now if I had been that close to her sex.

"Have you ever been with a young lady ?"my Sister asked, as if changing the field of study a little.

I shook my head.

"No titty gropes ?"she asked.

I shook my point again."fountainhead, not under the dress anyway !"I added.

"So you've kissed then ?"she asked.

I nodded.

"So you haven't seen a breast in the physique until the pic I sent you ?"she asked.

I shook my head again, but added that technically, that wasn't in the soma as it was a exposure so I still hadn't !

Chrissie pulled a face that said, ‘ truthful ’, before letting go of my radiocarpal joint completely, reaching around her dorsum where she proceeded to unclip her bra, taking it off.

I stared.

She smiled.

"Now you have !"she said.

I just continued to stare at their beauty.

I've heard many masses comment that they think she's already had a tit job at her young age, even though they are completely natural. They're just big, but the fact she is so sporty is the reason her bureau sinew help keep open them standing Nice and pert, and my god, did they take care pert.

"Wan na feel ?"she whispered, rocking her torso face to side, making them jiggle. Of course it also had the event of crusade down below too, but for some cause the compactness I was showing on her tits made me a niggling LE desperate to cum.

I think the broadness of my eye gave away my answer.

I reached up, noticing my bridge player were shaking slightly before placing a ribbon over each breast. Nipples pressed against my hands as I spread my fingerbreadth making it look like two soma coloured spiders were nestled on her tits.

And fuck me, did they palpate nice - just as soft as I imagined.

Chrissie smiled at me as she sat straddling my breast whilst I fondled her boobs, my peter resting between her butt cheeks.

"And by the way,"she said,"from the flavour against my arse I don't think you were too far out when you said the filmdom wouldn't be big enough for a penis selfie !"she added.

She gave another movement, only this fourth dimension pushed back and forth a distich of meter indicating exactly what she meant.

I just laughed,"I wouldn't say that !"I said.

As her arms were already by her incline to allow me access to her front, I suddenly felt fingerbreadth trace their way along my thigh and over the leg of my boxers. Then her digit wrapped around my beam, taking me in her appreciation whilst inching forward a little causing her puss to rub against my pubic mound as she gave a pleasurable groan of approval.

It hit me that she was getting her own pleasance from this little meeting from the look on her face, and who was I to spoil her fun ? !

Her deal pumped up and down my putz a couple of metre before I felt a finger slip down inside the fly of my boxers to lightly tickle my testicle. I was immediately jealous of any boyfriend she ever had or would experience knowing just how near she must be at this whole sex thing.

"Pinch my mamilla !"she said, looking me in the eye before closing hers to savour my touch. I lifted my hand to see her wonderful cadaver buds and took each one between finger and pollex, pinching gently. She ground her pussy into me a little harder whilst continuing to rub my erection in her hot palm as I pinched and rolled her teat between my digits.

She then moaned out loudly, a moan that I took to be of pleasure rather than anguish moving herself faster on top of me. Then I felt her shudder as a loud pant escaped her oral fissure which, even with my lack of practical sexual knowledge, told me that she was having an orgasm.

Which is the precise peak that I shot my load up her back !

I thrust up to fit her mitt movements adding to the pleasure of the pressure on her pussy, not to mention my continued pinching of her tit as we both rode our orgasms to an exquisite climax, her deal continuing its rhythm milking every close drop from me.

With our breaths still heavy, I let go of her boobs as she wiped her manus against the fabric of my boxers before leaning down close to me putting her lips to my ear. Her longsighted blonde hair tickled my face, not to mention her nipples now pressing against my own bureau as I felt her lovesome breath on the side of my face.

"There you go piffling brother, a delicacy for you, just from me"she whispered,"Now I'll leave you to clean house up your pickle whilst I go and have a quick rain shower, but if you promise to edit those pics then I'll let you fuck me later if you would like ?"she added.

She lifted herself from me and swung her leg over mine as she got off the bed, looking for the showtime time at my cum covered tool that was sticking out from my trunks. Just the words she had whispered had me standing to attention almost straight away to both mine and Chrissie's surprise.

"Mmm, looks like someone is already cutting !"she said, peeling her lash from her body to give me my first aspect of her delicious looking kitty. She then picked up her bra and phone walking to my door and opening it."I reckon we still have a couple of minute before mum gets home so I'll text edition Shaun and tell him I have a headache and am staying in tonight, as it looks like I've found something much more fun to do instead !"she said once more looking at my glistening erection.

With that, she was gone, leaving me lying there still throbbing wondering what the hell had just happened as she headed for the toilet .
