My telephone vibrated along with the sound of the tone to indicate a content 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 stop the net 90 seconds of play guessing that she was only abusing me in some way or was sending me a funny remark photograph she had found on the net.
As the last few seconds counted down my phone went again indicating a second message from her too.

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

I swiped the screen telling with my thumb to afford Chrissie's substance and sat gawping at the moving picture that met my gaze.

I stared at the screenland which was filled with a selfie picture of my sister in her underwear wondering why the hell she had sent it to me. Despite her grimace not showing, I obviously recognised her bed, not to mention a familiar packsack in the background so it was definitely her. I tapped on the side by side message and was met with another similar pic, only this time she had laid on the bed reaching over her shoulder to take a characterization of her bum showing her thong disappearing between her sweet-smelling arse brass !

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

I started to typecast 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 adopt my Nike rucksack ?"

I hit ‘ send ’.

I laughed out brassy and imagined the look on her facial expression when she realised she had sent the photo to me in error and would no dubiousness be banging on my threshold shortly begging for me to delete them.

I brought the pictures back up on screen to admire the vista, despite them being of my own babe. But there no denying she was hot, as all my mates would comment on how unspoiled it must be to deliver such a ‘ babe'as an older babe living under the Lapp ceiling. Of track I just shrugged it off, but without doubt it was certainly pretty damn good being her brother. We had always got on well together, having the usual sibling competition that kids do, but being nearly 3 age onetime than me she always went into ‘ protective'modal value when she needed to, which was possibly even warm 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 reckon about it, walking around the odd time in their knickerbockers and bra, although the lowest few calendar month they had seemed to pass over 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 gymnastic menage we were all quite fit and active causing the odd gag now and then as both mum and Chrissie always said they had the inauspicious thing of having big boobs. That was always met by dad's reaction of saying it was definitely no big trouble and one that I had started to agree with.

"But you don't have these affair bouncing around while you exercise !"mum would say cupping both breasts 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 entertain them for you then whilst you do it !"before mum slapped his hands away and laughed.

My telephone set suddenly buzzed as Chrissie replied.

"Shit bro, u got me ! Obv my misapprehension cos they should have gone to Shaun so how about u just erase 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 somebody with a figure 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 know ?"I asked, sending my reply.

My projection 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 incertitude the jolt will show his teammate anyway !"

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

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

There was a few minutes 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 to the lowest degree I didn't appearance him too much flesh ! Xx"

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

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

But my phone pinged again before I had hazard 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 pass on bosom exposed !

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

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

I looked at the image again whilst waiting for her response and my god did it count good. I even zoomed in to see the wonderful pap finding myself even admiring the artistic look of the picture from how the light hit her body. Her delicious looking tight trunk offset with pink ribbons and blonde hair. I found I was aching now in my groin as my putz pressed against my jeans.

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

Holy roll in the hay ! My own sister had sent me a pic of her own boob knowing full well it was for a treat to her little brother. I was already wondering how I could enshroud that picture away knowing it would probably present me enough wanking ammo for the next 50 years !

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

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

"Lol, deviate ! Xx"she replied.

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

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

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

"Thanks xx"came back.

"It matches the perfect bum"I said.

"U imagine ? 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 easy it would feel to stimulate my hand on it.

I have always been a bit of a joker so on a whim decided to strip to my boxers and guide a exposure of my bum which I sent to Chrissie with the textual matter ;"2 can flirt that game !"

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

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

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

I could hardly believe I was having this unearthly ‘ texting'conversation with my Sister, or should that be ‘ sexting'? The fact I was now standing in my bedroom in just my boxer 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 modest ! Xx"

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

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

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

"STEVEN ! Stop vaporing ! 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 make sent a pic of my own dick ? I considered having a quick search on the net for a word-painting of a Brobdingnagian knob to send but instead found one of a cockerel birdie, which obviously virtually people just forebode a turncock, and sent that.

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

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

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

"Very mirthful !"she said, holding her phone up with the picture of the razz on.

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

But not before she obviously saw the collapsible shelter !

"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 second base 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 outflank ‘ WTF'aspect and said,"Derrr, what force did you think your amazing body would have on me ?"

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

"And ?"I asked.

"And I perhaps should have known right !"she answered, now understanding properly."ejaculate 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 footstep 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 perspective despite the fact I was trying to get out of her way.

"Come on little Brother, 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 soundbox causing my senses to go into overload, but I was still conscious I didn't want to show off my naked penis !

I tried to dodge her again but she easily grabbed the edge of the pillow and yanked it hard causing me to grapple the early end as if now having a tug-of-war rivalry. But she was pretty warm and as much as I tried to stay fresh it in front of my crotch, it was now waistline altitude leaving me more exposed 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 battle causing me to lose my balance and surrender on the bed.

Chrissie just laughed making me please 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 dead body as if impressed that her picayune crony was growing fast. Then she tossed the pillow at my face which I used both hands to fend for myself with by catching it, giving her a seconds diversion 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 a great deal as I could give, and as the commotion subsided we found ourselves in a companion position we have been in probably hundreds of times over the years, with one of us straddling the former holding their arm down by the wrists, but none of them recently. And I think we both knew instantly why that was.

With her mammilla literally inches from my face, Chrissie sat back slightly releasing some of the pressure on my wrists, but as she did so her prat perched nicely onto my inguen as I felt my erection nestle somewhere between her cheeks ! I also knew instantly that with the minutes wrestling we had done, my hammer had come through the fly-hole at the front of my Boxer as I felt ‘ cutis on skin ’.

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

I stared straight in her oculus and nodded.

"SOB, sorry bro, I was only having a joke !"she said.

Her chest heaved and her toppingly world glistened with a lead of sweat.

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

"I'll close my oculus when I get off if you want ?"she said as if that would make me find better.

I just shrugged as I'm not sure it would be any less 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 centralize spirit 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 conceive of anything to cool down me down.

My only saving grace, or so I thought, was the fact my hard-on was pointing up the back of her whirl rather than against my torso under her pussy or I think I would possess spunked my encumbrance 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 field a little.

I shook my head.

"No knocker gropes ?"she asked.

I shook my head again."Well, not under the clothes anyway !"I added.

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

I nodded.

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

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

Chrissie pulled a boldness that said, ‘ true ’, before letting go of my wrist joint 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 titty job at her Whitney Young age, even though they are completely cancel. They're just big, but the fact she is so sporty is the reason her breast muscles help hold on them standing nice and pert, and my god, did they bet pert.

"Wan na feel ?"she whispered, rocking her body side to side, making them jiggle. Of course of instruction it also had the burden of movement down below too, but for some reason the concentration I was showing on her tit made me a little less do-or-die to cum.

I think the wideness of my eye 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 look like two material body coloured wanderer were nestled on her tits.

And fuck me, did they feel nice - just as flaccid as I imagined.

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

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

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

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

As her weapon were already by her position to give up me access to her front, I suddenly felt finger trace their way along my thigh and over the leg of my boxershorts. Then her digit wrapped around my shaft, taking me in her grasp whilst inching forward a petty causing her puss to rub against my pubic knoll as she gave a pleasurable groan of approval.

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

Her manus pumped up and down my cock a couplet of times before I felt a finger cabbage down inside the fly of my boxers to lightly tickle my balls. I was immediately overjealous of any boyfriend she ever had or would accept knowing just how practiced 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 fantastic stiff buds and took each one between digit and thumb, pinching gently. She ground her pussy into me a short harder whilst continuing to rub my erecting in her hot medallion as I pinched and rolled her pap between my digits.

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

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

I thrust up to come across her paw movements adding to the pleasure of the press on her pussy, not to mention my continued pinching of her pap as we both rode our orgasms to an exquisite climax, her hired hand continuing its beat milking every last drop curtain from me.

With our breaths still heavy, I let go of her boobs as she wiped her hand against the stuff of my boxers before leaning down close to me putting her brim to my ear. Her recollective blonde tomentum tickled my fount, not to mention her nipples now pressing against my own pectus as I felt her ardent 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 cleanse up your mess whilst I go and have a flying shower bath, but if you promise to delete 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 offset time at my cum covered stopcock that was sticking out from my short pants. Just the words she had whispered had me standing to care almost straight away to both mine and Chrissie's surprise.

"Mmm, looks like someone is already keen !"she said, peeling her thong from her soundbox to chip in me my first-class honours degree view of her delicious looking slit. She then picked up her bra and phone walk to my door and opening it."I reckon we still have a mates of 60 minutes before mum gets home so I'll school text Shaun and enjoin 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 bathroom .
