My phone vibrated along with the sound of the tone to show a message had been received. I was nearing the end of the game on my PlayStation in my way as I glanced at the speech sound to see my sister's name as the sender so decided to wind up the stopping point 90 mo of play guessing that she was only abusing me in some way or was sending me a funny picture she had found on the net.
As the live few minute counted down my telephone went again indicating a second message from her too.

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

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

I stared at the sieve which was filled with a selfie depiction of my sister in her underclothes wondering why the infernal region she had sent it to me. Despite her face not showing, I obviously recognised her bed, not to advert a familiar back pack in the background so it was definitely her. I tapped on the next substance and was met with another similar pic, only this clip she had laid on the bed reaching over her shoulder joint to take a picture of her bum showing her thong disappearing between her perfumed prat cheeks !

It occurred to me that she had Thomas More than likely sent them to me in mistake 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 fault - and btw, who said u could borrow my Nike knapsack ?"

I hit ‘ send ’.

I laughed out gimcrack and imagined the look on her face when she realised she had sent the pic to me in error and would no doubt be banging on my room access shortly begging for me to delete them.

I brought the pictures back up on concealment to admire the view, despite them being of my own sis. But there no denying she was hot, as all my mates would comment on how good it must be to make such a ‘ baby'as an older sister living under the Sami cap. Of course of study 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 common sibling competition that tyke do, but being nearly 3 age older than me she always went into ‘ protective'mode when she needed to, which was possibly even secure 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 mean about it, walking around the odd metre in their knickers and bra, although the live on few month they had seemed to cover up more as they saw me maturing quickly myself. Chrissie would even razz me now and then when certain things popped up in conversation, but naught malicious. Being an athletic household we were all quite an 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 reaction of saying it was definitely no big trouble 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 hands and giving them a squeeze.

Dad would then make a motion around behind her and pass on round to cup them himself saying ;"here, let me check them for you then whilst you do it !"before mum slapped his hands away and laughed.

My telephone suddenly buzzed as Chrissie replied.

"Shit bro, u got me ! Obv my mistake cos they should make gone to Shaun so how about u just edit 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 someone with a epithet starting with my initial, meaning I at to the lowest degree 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 person u hardly know ?"I asked, sending my reply.

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

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

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

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

There was a few minutes before she replied making me question 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 a good deal chassis ! Xx"

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

diddley ! Did I just admit to my baby 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 apologise without sounding like some pervy prowler now !

But my phone pinged again before I had chance to answer with a message from her ;
"You mean like this ? Xx"she put, and sent a mental picture of her laid on her vertebral column with her left breast exposed !

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

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

I looked at the photograph again whilst waiting for her reaction and my god did it look near. I even zoomed in to see the wonderful mammilla finding myself even admiring the artistic looking of the motion picture from how the visible light hit her body. Her delicious looking fuddled organic structure offset with pink decoration and blonde hair. I found I was aching now in my mole as my cock pressed against my jeans.

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

Holy screwing ! My own babe had sent me a pic of her own tit knowing fully well it was for a treat to her small comrade. I was already wondering how I could hide that picture away knowing it would probably give me enough wanking ammunition for the future 50 twelvemonth !

"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, 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 perfect bum"I said.

"U guess ? Xx"she replied.

"Shit, deffo sis, u must surely fuck 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 finger to have my deal on it.

I have always been a bit of a joker so on a caprice decided to loot to my boxers and take in a picture of my bum which I sent to Chrissie with the text ;"2 can play that game !"

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

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

I felt my supercilium rise as I pondered the question. So obviously I took a photo of my own bare dresser and sent it !

I could hardly believe 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 bagger with an erection pushing against the front led me to consider that perhaps I was in fact ‘ sexting'with my Sister !

"LOL, OK, you got me Steven, very suspicious as I was worried your pic might have got been lower ! Xx"

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

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

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

"STEVEN ! Stop 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 ready lookup on the net for a picture of a huge boss to send but instead found one of a cockerel fowl, which obviously nigh people just call a stopcock, and sent that.

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

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

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

"Very funny !"she said, holding her phone 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 item whilst I had the chance in the few arcsecond 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 best ‘ WTF'face and said,"Derrr, what effect did you cogitate your amazing body would cause on me ?"

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

"And ?"I asked.

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

"No way !"I spat out.

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

"Chrissie, get off !"I said trying to duck her range. Her nipple bounced seductively as she reached forward which made for a lovely purview 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 nostril adding to the sight of her soused soundbox causing my pot to go into overburden, but I was still conscious I didn't want to evince off my raw penis !

I tried to dodge her again but she easily grabbed the edge of the pillow and yanked it laborious causing me to grip the former end as if now having a tug-of-war contender. But she was pretty strong and as lots as I tried to hold open it in front of my crotch, it was now waist height leaving me more bring out 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 pillow fight causing me to lose my residuum and autumn 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 interference was.

She looked down at me, her eyes appraising my body as if impressed that her small brother was growing fast. Then she tossed the pillow at my face which I used both custody to defend myself with by catching it, giving her a mo 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 practically as I could have, and as the commotion subsided we found ourselves in a familiar position we have been in probably hundred of metre over the yr, 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 human face, Chrissie sat back slightly releasing some of the pressure sensation on my wrists, but as she did so her rump perched nicely onto my groyne as I felt my erection nestle somewhere between her cheeks ! I also knew instantly that with the transactions wrestling we had done, my cock had come through the fly-hole at the front of my boxershorts as I felt ‘ tegument on skin ’.

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

I stared straight in her centre and nodded.

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

Her bureau heaved and her marvellously globes glistened with a hint of sweat.

I felt a twinge in my cock as yet Sir Thomas More blood rushed to it making it as stiff as I think I have ever known.

"I'll airless 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 sure it would be any less stymie 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 concentrated facial expression on my face.

I nodded, but I think she clocked the grounds."Do you require 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 book binding of her crack rather than against my trunk under her cunt 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 Sister asked, as if changing the subject a little.

I shook my head.

"No boob gropes ?"she asked.

I shook my head again."fountainhead, not under the clothes 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 drumhead again, but added that technically, that wasn't in the flesh as it was a picture so I still hadn't !

Chrissie pulled a human face that said, ‘ rightful ’, 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 mass comment that they think she's already had a tit job at her untested age, even though they are completely cancel. They're just big, but the fact she is so sporty is the reasonableness her chest muscles help save them standing prissy and pert, and my god, did they look pert.

"Wan na experience ?"she whispered, rocking her body side to side, making them jiggle. Of course it also had the consequence of movement down below too, but for some reason the concentration I was showing on her pap made me a piddling less despairing to cum.

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

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

And bonk me, did they feel gracious - just as subdued as I imagined.

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

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

She gave another move, only this time pushed back and forth a pair of multiplication indicating exactly what she meant.

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

As her branch were already by her English to tolerate me access to her front, I suddenly felt digit trace their way along my second joint and over the leg of my bagger. Then her fingers wrapped around my shaft, taking me in her clench whilst inching forward a petty causing her kitty to rub against my pubic mound as she gave a pleasurable groan of approval.

It hit me that she was getting her own pleasure from this niggling coming together from the look on her face, and who was I to spoil her fun ? !

Her hand pumped up and down my rooster a couple of multiplication before I felt a finger's breadth sneak down inside the fly of my boxers to lightly vellicate my balls. I was immediately covetous of any young man she ever had or would have got knowing just how good she must be at this unanimous sex thing.

"speck my nipples !"she said, looking me in the eye before closing hers to savour my soupcon. I lifted my hands to see her wonderful clay buds and took each one between finger and thumb, pinching gently. She ground her pussy into me a short harder whilst continuing to rub my hard-on in her hot palm as I pinched and rolled her nipples between my digits.

She then moaned out loud, 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 loudly gasp escaped her rima oris which, even with my lack of practical sexual noesis, told me that she was having an orgasm.

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

I thrust up to fulfill her hand movements adding to the pleasure of the pressure on her pussy, not to advert my persist in pinching of her nipples as we both rode our orgasms to an recherche climax, her bridge player continuing its rhythm milking every endure drop from me.

With our breathing space still heavy, I let go of her knocker as she wiped her hand against the material of my boxers before leaning down close to me putting her lips to my ear. Her long blonde pilus tickled my boldness, not to mention her nipples now pressing against my own chest as I felt her warm intimation 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 pick up your mess whilst I go and have a agile cascade, but if you promise to erase those pics then I'll let you fuck 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 foremost time at my cum covered pecker that was sticking out from my shorts. Just the password she had whispered had me standing to attention 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 give me my first position of her delightful looking snatch. She then picked up her bra and phone walking to my door and opening it."I reckon we still have a couple of time of day before mum gets base so I'll text Shaun and secernate him I have a worry 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 .
