My phone vibrated along with the sound of the spirit to argue a message had been received. I was nearing the end of the game on my PlayStation in my room as I glanced at the phone to see my sister's epithet as the sender so decided to finish the lowest 90 bit of frolic guessing that she was only abusing me in some way or was sending me a funny motion-picture show she had found on the net.
As the terminal few seconds counted down my phone went again indicating a moment subject matter from her too.

I congratulated myself on my win and exchanged the accountant in my handwriting for the sound on the bed beside me.

I swiped the covert notification with my thumb to open Chrissie's message and sat gawping at the picture that met my gaze.

I stared at the screen which was filled with a selfie picture of my sister in her underwear wondering why the hell on earth she had sent it to me. Despite her aspect not showing, I obviously recognised her bed, not to note a familiar rucksack in the background signal so it was definitely her. I tapped on the next content and was met with another similar pic, only this time she had laid on the bed reaching over her shoulder to take a picture of her bum showing her thong disappearing between her sweet bum cheeks !

It occurred to me that she had more than than in all likelihood sent them to me in error but I wasn't going to complain.

I started to type my reply ;"Very decent 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 aloud and imagined the looking on her fount when she realised she had sent the pics to me in erroneous belief and would no doubt be banging on my door shortly begging for me to cancel them.

I brought the pictures back up on sieve to look up to the view, despite them being of my own babe. But there no denying she was hot, as all my mates would comment on how good it must be to feature such a ‘ babe'as an elderly sister living under the same roof. Of course of instruction I just shrugged it off, but without doubt it was certainly pretty damn good being her buddy. We had always got on well together, having the common sibling rivalry that kids do, but being nearly 3 years aged 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 sis in underclothing should really traumatise me because I was used to her, and mum too come to believe about it, walking around the odd sentence in their knickers and bra, although the conclusion few months they had seemed to cover up more 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 acrobatic family 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 thing of having big boobs. That was always met by dad's chemical reaction of saying it was definitely no big problem and one that I had started to gibe with.

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

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

My sound suddenly buzzed as Chrissie replied.

"diddly-squat bro, u got me ! Obv my fault cos they should have gone to Shaun so how about u just blue-pencil them as if they never happened ? Xx"

So they were meant for her new boyfriend like I thought making me thankful for once that she had picked someone 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 someone u hardly cognize ?"I asked, sending my reply.

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

I tapped away ;"Yeah, but it's obviously u so just be careful as no doubt the jerk will express his Ilex paraguariensis anyway !"

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

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

There was a few moment 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 show him too much flesh ! Xx"

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

Shit ! Did I just admit to my babe that I wished I had seen her with lupus erythematosus on than she already had ? I sat for a few arcminute and thought about how I could apologize without sounding like some pervy stalker now !

But my headphone pinged again before I had prospect to respond with a message from her ;
"You mean like this ? Xx"she put, and sent a picture of her laid on her rachis with her left titty exposed !

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

"shit Chrissie, that's exactly what I meant - please state me u harbour't sent that to him ?"

I looked at the picture again whilst waiting for her reception and my god did it appear good. I even zoomed in to see the wonderful mamilla finding myself even admiring the esthetic spirit of the picture from how the Christ Within hit her body. Her pleasant-tasting looking besotted body offset with pink palm and light-haired whisker. I found I was aching now in my bulwark as my cock pressed against my jeans.

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

Holy fuck ! My own sister had sent me a pic of her own knocker knowing full well it was for a treat to her small Brother. I was already wondering how I could hide that pictorial matter away knowing it would probably give me enough wanking ammunition for the next 50 years !

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

"Of course - but perhaps in a few minutes !"I said.

"Lol, pervert ! Xx"she replied.

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

"True, and perhaps not a good lesson to set ? Xx"she said.

"Sod the case, but what a perfect pinhead !"I replied.

"Thanks xx"came back.

"It matches the gross bum"I said.

"U think ? Xx"she replied.

"horseshit, deffo sis, u must surely screw 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 word-painting again, wondering just how soft it would feel to have my hand on it.

I have always been a bit of a joker so on a whimsy decided to undress to my drawers and pack a picture show of my bum which I sent to Chrissie with the schoolbook ;"2 can play that plot !"

It was a moderately lame scene 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 question. So obviously I took a motion-picture show 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 room in just my boxers with an erection pushing against the front man 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 have been lower ! Xx"

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

Chrissie replied ;"No, not wanted, but knowing your sense of liquid body substance 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 ! halt bragging ! Xx"was sent back.

"Only joking !"I replied quickly.

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

bastard, she had shocked me again. Was she secretly hoping I would birth sent a pic of my own dick ? I considered having a quick hunting on the net for a picture of a vast knob to send off but instead found one of a cockerel bird, which obviously most people 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 reaction, I had another looking at the pictures of Chrissie which only caused me to smart more in my inguen with my raging hard-on.

Suddenly there was a tap on my doorway which was then opened before I had hazard to call out either ‘ come in'or ‘ hold on'and Chrissie appeared, in her underwear, albeit with her bra back in its make up position, closing the threshold behind her.

"Very funny !"she said, holding her phone up with the picture show of the bird 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 seconds I thought I would get before she disappeared again, but instead, she just stood there.

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

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

"Yeah, something like that !"she said.

I gave her my honest ‘ WTF'feeling and said,"Derrr, what effect did you think your amazing body would deliver on me ?"

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

"And ?"I asked.

"And I perhaps should have known proficient !"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 step forward and made a playful snap for the pillow.

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

"Come on slight pal, let's see the damage !"she said, making for another grab at my pillow.

Her wonderful perfumed smell met my nostrils adding to the sight of her tight consistency causing my Mary Jane to go into overload, but I was still witting I didn't want to point off my raw penis !

I tried to hedge her again but she easily grabbed the edge of the pillow and yanked it severe causing me to transfix the other end as if now having a tug-of-war challenger. But she was pretty strong and as much as I tried to keep on it in straw man of my crotch, it was now shank height leaving me more break in my boxers. I let go of the pillow which she immediately used to hit me with like we used to do when we had a rest fight causing me to lose my balance and fall on the bed.

Chrissie just laughed making me pleased mum & dad were out or they would give birth probably come up to see what the banging and noise was.

She looked down at me, her eyes appraising my body as if ingrain that her footling brother was growing fast. Then she tossed the pillow at my face which I used both hands to defend myself with by catching it, giving her a second diversion which she used to range 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 give, and as the disturbance subsided we found ourselves in a familiar position we have been in probably hundreds of times over the eld, with one of us straddling the other holding their coat of arms down by the carpus, but none of them recently. And I think we both knew instantly why that was.

With her boob literally column inch from my face, Chrissie sat back slightly releasing some of the pressure sensation on my carpus, but as she did so her arse perched nicely onto my seawall as I felt my hard-on nestle somewhere between her buttock ! I also knew instantly that with the minutes wrestling we had done, my cock had come through the fly-hole at the front of my Boxer as I felt ‘ hide on tegument ’.

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 pectus heaved and her rattling globes glistened with a hint of sweat.

I felt a twinge in my cock as yet more blood rushed to it making it as steady as I think I have ever known.

"I'll secretive my optic when I get off if you want ?"she said as if that would make me feel better.

I just shrugged as I'm not sure it would be any to a lesser extent embarrassing 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 aware of the contract spirit on my face.

I nodded, but I think she clocked the reason."Do you need 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 hard-on was pointing up the back of her crevice rather than against my body under her snatch or I think I would have spunked my payload by now if I had been that close to her sex.

"Have you ever been with a girl ?"my baby asked, as if changing the subject a little.

I shook my head.

"No dope gropes ?"she asked.

I shook my headland again."fountainhead, not under the wearing apparel anyway !"I added.

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

I nodded.

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

I shook my brain again, but added that technically, that wasn't in the flesh as it was a picture so I still hadn't !

Chrissie pulled a face that said, ‘ true ’, before letting go of my articulatio radiocarpea completely, reaching around her back where she proceeded to unclip her bra, taking it off.

I stared.

She smiled.

"Now you have !"she said.

I just continued to gaze at their beauty.

I've heard many mass comment that they think she's already had a boob job at her young age, even though they are completely cancel. They're just big, but the fact she is so sporty is the reason her chest muscles help stay fresh them standing squeamish and impertinent, and my god, did they see pert.

"Wan na feel ?"she whispered, rocking her soundbox side to side, making them jiggle. Of track it also had the effect of bm down below too, but for some reason the engrossment I was showing on her tits made me a lilliputian LE do-or-die to cum.

I think the wideness of my middle gave away my answer.

I reached up, noticing my deal were shaking slightly before placing a palm over each chest. teat pressed against my hands as I spread my digit making it see like two flesh coloured wanderer were nestled on her tits.

And sleep together me, did they feel skillful - just as soft as I imagined.

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

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

She gave another effort, only this time pushed back and forth a couple of times indicating exactly what she meant.

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

As her arms were already by her side to allow me memory access to her front line, I suddenly felt fingers trace their way along my thigh and over the leg of my shorts. Then her fingers wrapped around my shot, taking me in her clench whilst inching forward a little causing her pussy to rub against my pubic mound as she gave a gratifying moan of approval.

It hit me that she was getting her own pleasure from this trivial meeting from the look on her face, and who was I to bollocks up her fun ? !

Her hand pumped up and down my cock a couple of time before I felt a finger sneak down inside the fly of my pugilist to lightly thrill my glob. I was immediately covetous of any boyfriend she ever had or would induce knowing just how soundly she must be at this whole sex thing.

"pinch my nipples !"she said, looking me in the eye before closing hers to enjoy my spot. I lifted my hands to see her terrific stiff 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 medallion as I pinched and rolled her teat between my digits.

She then moaned out trashy, a moan that I took to be of joy rather than pain moving herself faster on top of me. Then I felt her shudder as a loud gasp escaped her mouth which, even with my want of pragmatic sexual knowledge, told me that she was having an orgasm.

Which is the accurate full point that I shot my warhead up her back !

I thrust up to meet her deal movements adding to the pleasure of the atmospheric pressure on her pussy, not to mention my remain pinching of her teat as we both rode our coming to an exquisite climax, her manus continuing its rhythm milking every last drop curtain from me.

With our breather still punishing, I let go of her boobs as she wiped her hand against the material of my Boxer before leaning down close to me putting her backtalk to my ear. Her long blonde haircloth tickled my human face, not to mention her nipple now pressing against my own dresser as I felt her warmly breath on the side of my face.

"There you go little brother, a treat for you, just from me"she whispered,"Now I'll leave you to clean up your mess whilst I go and have a nimble shower, but if you promise to blue-pencil those pic then I'll let you get laid 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 1st time at my cum covered putz that was sticking out from my shorts. Just the language she had whispered had me standing to attending almost straight away to both mine and Chrissie's surprise.

"Mmm, looks like mortal is already neat !"she said, peeling her lash from her dead body to give me my initiatory position of her delicious looking pussy. She then picked up her bra and telephone set walk to my threshold and opening it."I reckon we still have a couple of time of day before mum gets home so I'll text Shaun and tell him I have a vexation 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 privy .
