My phone vibrated along with the sound of the tone to indicate 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 babe's figure as the sender so decided to end up the lastly 90 seconds of play guessing that she was only abusing me in some way or was sending me a odd depiction she had found on the net.
As the concluding few seconds counted down my telephone went again indicating a second message from her too.

I congratulated myself on my win and exchanged the control in my script for the phone on the bed beside me.

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

I stared at the screen door which was filled with a selfie picture of my sister in her underwear wondering why the Inferno she had sent it to me. Despite her boldness not showing, I obviously recognised her bed, not to refer a conversant rucksack in the background so it was definitely her. I tapped on the following message and was met with another similar pic, only this time she had laid on the bed reaching over her shoulder to direct a picture of her bum showing her thong disappearing between her gratifying arse cheeks !

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

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

I hit ‘ send ’.

I laughed out forte and imagined the look on her brass when she realised she had sent the pic to me in wrongdoing and would no question be banging on my threshold shortly begging for me to delete them.

I brought the depiction back up on screen to admire the view, despite them being of my own sister. But there no denying she was hot, as all my mates would comment on how soundly it must be to sustain such a ‘ sister'as an onetime sister living under the same cap. Of path I just shrugged it off, but without doubt it was certainly pretty damn in force being her brother. We had always got on well together, having the usual sib rivalry that fry do, but being nearly 3 years older than me she always went into ‘ protective'style when she needed to, which was possibly even stronger now she was 21.

Not that seeing my sister in underwear should really shock me because I was used to her, and mum too come to think about it, walking around the odd time in their knickerbockers and bra, although the last few 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 sure things popped up in conversation, but nothing malicious. Being an athletic 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 person thing of having big boobs. That was always met by dad's reaction of saying it was definitely no big problem and one that I had started to agree with.

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

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

My phone suddenly buzzed as Chrissie replied.

"Shit bro, u got me ! Obv my mistake cos they should have 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 thankful for once that she had picked person 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 soul u hardly know ?"I asked, sending my reply.

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

I tapped away ;"Yeah, but it's obviously u so just be deliberate as no dubiousness the jerk will show his mates 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 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 display him too much anatomy ! Xx"

"Which is a damn shame seeing's how I got them in erroneous belief !"I replied.

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

But my phone pinged again before I had chance to reply with a subject matter from her ;
"You mean like this ? Xx"she put, and sent a picture of her laid on her backrest with her left breast exposed !

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

"Shit Chrissie, that's exactly what I meant - please tell me u haven't sent that to him ?"

I looked at the picture again whilst waiting for her reception and my god did it look good. I even zoomed in to see the grand nipple finding myself even admiring the artistic look of the icon from how the Christ Within hit her body. Her scrumptious looking mingy body offset with pink ribbons and blonde hair. I found I was aching now in my groin as my cock pressed against my jeans.

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

sanctum nooky ! My own sister had sent me a pic of her own boob knowing full well it was for a dainty to her slight Brother. I was already wondering how I could hide that pic away knowing it would probably give me adequate wank ammunition for the succeeding 50 years !

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

"Of class - 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 illustration to set ? Xx"she said.

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

"Thanks xx"came back.

"It matches the gross bum"I said.

"U think ? Xx"she replied.

"dirt, 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 feel to have my hand on it.

I have always been a bit of a joker so on a whimsy decided to strip to my boxer and take a word picture of my bum which I sent to Chrissie with the text ;"2 can play that secret plan !"

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

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

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

I could hardly think I was having this weird ‘ texting'conversation with my sister, or should that be ‘ sexting'? The fact I was now standing in my bedroom in just my shorts with an erection 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 have been lower ! Xx"

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

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

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

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

"Only joking !"I replied quickly.

"Perhaps I should be the evaluator 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 picture of a vast knob to air but instead found one of a cockerel bird, which obviously most people just call a cock, and sent that.

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

Whilst I was waiting for a reaction, I had another look at the pictorial matter of Chrissie which only caused me to pine more in my groin with my raging hard-on.

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

"Very funny story !"she said, holding her earpiece up with the picture 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 bit 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 effect on me ?"I finished.

"Yeah, something like that !"she said.

I gave her my sound ‘ WTF'looking at and said,"Derrr, what effect did you think your amazing body would make on me ?"

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

"And ?"I asked.

"And I perhaps should have known respectable !"she answered, now understanding properly."ejaculate on then, seeing as I'm here, let's have a flavour !"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 grab for the pillow.

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

"seminal fluid on fiddling brother, let's see the terms !"she said, making for another grab at my pillow.

Her wonderful perfumed smell met my nostrils adding to the passel of her tight body causing my mother wit to go into overload, but I was still conscious I didn't want to establish off my naked member !

I tried to dodge her again but she easily grabbed the edge of the pillow and yanked it hard causing me to transfix the former end as if now having a tug-of-war contest. But she was pretty strong and as a great deal as I tried to sustain it in strawman of my crotch, it was now shank peak leaving me more exposed in my Boxer. 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 recede my Libra the 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 banging and noise was.

She looked down at me, her eyes appraising my body as if yarn-dye that her niggling brother was growing fast. Then she tossed the pillow at my fount which I used both hands to represent myself with by catching it, giving her a indorse 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 very much as I could have, and as the hoo-ha subsided we found ourselves in a fellow location we have been in probably one C of sentence over the age, with one of us straddling the early holding their coat of arms down by the wrists, but none of them recently. And I think we both knew instantly why that was.

With her bosom literally in from my nerve, Chrissie sat back slightly releasing some of the imperativeness on my carpus, but as she did so her buttocks 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 cock had come through the fly-hole at the battlefront of my boxer as I felt ‘ skin on skin ’.

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

I stared straight in her center and nodded.

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

Her breast heaved and her wondrous globe glistened with a hint of sweat.

I felt a pang in my shaft as yet more blood rushed to it making it as unbendable as I think I have ever known.

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

I just shrugged as I'm not indisputable it would be any less blockade now. But she then moved again, her bum brass rubbing me and for a second I honestly thought I was going to cum !

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

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

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

My only saving state of grace, or so I thought, was the fact my erecting was pointing up the back of her crack rather than against my body under her twat or I think I would let spunked my lode by now if I had been that close to her sex.

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

I shook my head.

"No boob gropes ?"she asked.

I shook my pass again."well, not under the wearing apparel anyway !"I added.

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

I nodded.

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

I shook my chief again, but added that technically, that wasn't in the flesh as it was a word-painting so I still hadn't !

Chrissie pulled a side that said, ‘ dependable ’, before letting go of my wrists 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 stare at their beauty.

I've heard many people comment that they think she's already had a boob job at her young age, even though they are completely born. They're just big, but the fact she is so sporty is the reason her chest muscles help keep on them standing nice and pert, and my god, did they bet pert.

"Wan na experience ?"she whispered, rocking her body side to side, making them jiggle. Of trend it also had the result of effort down below too, but for some reasonableness the concentration I was showing on her tits made me a fiddling less desperate to cum.

I think the immensity of my heart gave away my answer.

I reached up, noticing my hands were shaking slightly before placing a palm over each breast. Nipples pressed against my hands as I spread my fingers making it front like two flesh coloured spiders were nestled on her tits.

And fuck me, did they feel overnice - just as voiced 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 CRT screen wouldn't be big enough for a penis selfie !"she added.

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

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

As her arms were already by her position to allow me approach to her front, I suddenly felt finger's breadth trace their way along my second joint and over the leg of my boxers. Then her finger wrapped around my irradiation, taking me in her grasp whilst inching forward a little causing her slit to rub against my pubic mound as she gave a pleasurable moan of approval.

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

Her hand pumped up and down my prick a duad of times before I felt a finger sneak down inside the fly of my boxers to lightly thrill my glob. I was immediately overjealous of any beau she ever had or would have knowing just how unspoiled she must be at this whole sex thing.

"speck my nipples !"she said, looking me in the eye before closing hers to enjoy my touch. I lifted my hands to see her terrific cadaver buds and took each one between finger and quarter round, pinching gently. She ground her slit into me a piffling harder whilst continuing to rub my hard-on in her hot palm as I pinched and rolled her mamilla between my digits.

She then moaned out garish, a moan that I took to be of delight rather than pain moving herself faster on top of me. Then I felt her shudder as a forte gasp escaped her mouth which, even with my lack of hard-nosed sexual knowledge, told me that she was having an orgasm.

Which is the precise point that I shot my lading up her back !

I thrust up to cope with her hand movements adding to the pleasure of the pressure on her pussy, not to mention my go forward pinching of her teat as we both rode our climax to an keen coming, her hand continuing its calendar method milking every last drop from me.

With our breathing time still grave, I let go of her boobs as she wiped her helping hand against the material of my boxers before leaning down close to me putting her lips to my ear. Her yearn light-haired hair tickled my typeface, not to bring up her pap now pressing against my own thorax as I felt her warm breathing spell on the side of my face.

"There you go slight brother, a treat for you, just from me"she whispered,"Now I'll leave you to clean up your lot whilst I go and have a quick shower, but if you promise to delete those pics then I'll let you know me later if you would like ?"she added.

She lifted herself from me and sway her leg over mine as she got off the bed, looking for the outset time at my cum covered cock that was sticking out from my short pants. Just the words she had whispered had me standing to tending almost straight away to both mine and Chrissie's surprise.

"Mmm, looks like someone is already keen !"she said, peeling her thong from her body to grant me my foremost view of her delicious looking pussy. She then picked up her bra and telephone walk to my door and opening it."I reckon we still have a brace of hours before mum gets family so I'll text 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 bathroom .
