My phone vibrated along with the audio of the tone to indicate a message had been received. I was nearing the end of the biz on my PlayStation in my room as I glanced at the sound to see my sister's name as the transmitter so decided to finish the last 90 seconds of caper guessing that she was only abusing me in some way or was sending me a fishy impression she had found on the net.
As the finally few s counted down my earpiece went again indicating a second substance from her too.

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

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

I stared at the screen which was filled with a selfie photograph of my baby in her underwear wondering why the hell she had sent it to me. Despite her boldness not showing, I obviously recognised her bed, not to refer a conversant knapsack in the background so it was definitely her. I tapped on the adjacent substance and was met with another alike pic, only this time she had laid on the bed stretch over her shoulder to take a scene of her bum showing her thong disappearing between her sweet behind cheeks !

It occurred to me that she had to a greater extent than potential sent them to me in error 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 knapsack ?"

I hit ‘ send ’.

I laughed out gimcrack and imagined the look on her human face when she realised she had sent the moving-picture show to me in wrongdoing and would no doubt be banging on my doorway shortly begging for me to delete them.

I brought the pictures back up on blind to admire the horizon, despite them being of my own Sister. But there no denying she was hot, as all my mates would remark on how good it must be to cause such a ‘ babe'as an older sis living under the same roof. Of course I just shrugged it off, but without dubiousness it was certainly pretty damn unspoiled being her brother. We had always got on well together, having the usual sibling rivalry that kids do, but being nearly 3 years 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 sister in underclothes should really shock me because I was used to her, and mum too come to think about it, walking around the odd metre in their knee pants and bra, although the last few calendar month they had seemed to cover up more as they saw me maturing quickly myself. Chrissie would even pester me now and then when sealed things popped up in conversation, but zippo malicious. Being an gymnastic family we were all quite an fit and alive causing the odd jocularity now and then as both mum and Chrissie always said they had the unfortunate matter 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 affair 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 reach round to cup them himself saying ;"here, let me confine them for you then whilst you do it !"before mum slapped his hands away and laughed.

My sound suddenly buzzed as Chrissie replied.

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

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

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

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

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

"U r joking ? He'll gasconade 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 least I didn't appearance him too very much flesh ! Xx"

"Which is a shucks 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 instant and thought about how I could apologise without sounding like some pervy stalker 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 picture of her laid on her rachis with her left breast exposed !

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

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

I looked at the motion-picture show again whilst waiting for her reaction and my god did it take care expert. I even zoomed in to see the tremendous mamilla finding myself even admiring the esthetic spirit of the word-painting from how the luminousness hit her trunk. Her delicious looking tight organic structure offset with pinkish ribbons and blonde hair. I found I was aching now in my groyne as my dick pressed against my jeans.

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

Holy nooky ! My own sister had sent me a pic of her own boob knowing full well it was for a treat to her little buddy. I was already wondering how I could hide that picture away knowing it would probably contribute me enough wanking ammo for the side by side 50 geezerhood !

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

"Of grade - but perhaps in a few instant !"I said.

"Lol, pervert ! Xx"she replied.

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

"True, and perhaps not a sound example 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 think ? Xx"she replied.

"Shit, deffo sis, u must surely cognise 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 subdued it would feel to have my hand on it.

I have always been a bit of a joker so on a whim decided to discase to my pugilist and subscribe a motion-picture show of my bum which I sent to Chrissie with the text ;"2 can spiel that game !"

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

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

I felt my supercilium rise as I pondered the question. 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 chamber in just my boxers with an erection pushing against the front led me to believe that perhaps I was in fact ‘ sexting'with my babe !

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

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

Chrissie replied ;"No, not wanted, but knowing your sense of mood 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 ! block crowing ! Xx"was sent back.

"Only joking !"I replied quickly.

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

Shit, she had shocked me again. Was she secretly hoping I would have sent a pic of my own prick ? I considered having a quick hunting on the net for a picture of a huge knob to send but instead found one of a cockerel shuttle, which obviously near citizenry just call a pecker, 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 facial expression 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 doorway which was then opened before I had chance to shout either ‘ come in'or ‘ hold on'and Chrissie appeared, in her underclothing, albeit with her bra back in its correct status, closing the door behind her.

"Very curious !"she said, holding her phone up with the movie of the shuttlecock 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 core on me ?"I finished.

"Yeah, something like that !"she said.

I gave her my best ‘ WTF'look and said,"Derrr, what essence did you retrieve 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 make known near !"she answered, now understanding properly."seminal fluid on then, seeing as I'm here, let's have a looking at !"she suddenly added, nodding down at the pillow and obviously referring to my cock.

"No way !"I spat out.

She took a footprint 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 vista despite the fact I was trying to get out of her way.

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

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

I tried to hedge her again but she easily grabbed the sharpness of the pillow and yanked it hard causing me to fascinate the other end as if now having a tug-of-war competition. But she was pretty substantial and as very much as I tried to go on it in front of my crotch, it was now waist height 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 fight causing me to lose my Balance and dip on the bed.

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

She looked down at me, her eyes appraising my body as if instill that her little brother was growing fast. Then she tossed the pillow at my font which I used both paw to fend for myself with by catching it, giving her a s 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 much as I could throw, and as the ruckus subsided we found ourselves in a familiar position we have been in probably hundreds of times over the years, with one of us straddling the other holding their weapons system down by the carpus, but none of them recently. And I think we both knew instantly why that was.

With her tits literally inch from my face, Chrissie sat back slightly releasing some of the pressure on my wrists, but as she did so her buns 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 cock had come through the fly-hole at the strawman of my boxers as I felt ‘ skin on peel ’.

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

I stared straight in her eyes and nodded.

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

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

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

"I'll closelipped 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 for certain 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 concentrated flavour on my face.

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

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

My only saving state of grace, or so I thought, was the fact my hard-on was pointing up the back of her crack rather than against my body under her cunt or I think I would have spunked my load by now if I had been that close to her sex.

"Have you ever been with a missy ?"my Sister asked, as if changing the national a little.

I shook my head.

"No boob gropes ?"she asked.

I shook my head 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 dummy in the flesh until the pic I sent you ?"she asked.

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

Chrissie pulled a face that said, ‘ true ’, before letting go of my wrists completely, reaching around her binding 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 blunder job at her young age, even though they are completely born. They're just big, but the fact she is so sporty is the intellect her chest of drawers muscles help retain them standing nice and saucy, and my god, did they look pert.

"Wan na feel ?"she whispered, rocking her torso side to side, making them jiggle. Of course of action it also had the effect of move down below too, but for some reason the concentration I was showing on her mamilla made me a little less desperate to cum.

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

I reached up, noticing my script were shaking slightly before placing a medal over each titty. pap pressed against my paw as I spread my fingers making it reckon like two figure coloured spider were nestled on her tits.

And be intimate me, did they feel decent - just as soft as I imagined.

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

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

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

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

As her weaponry were already by her side to allow me admittance to her front, I suddenly felt fingerbreadth trace their way along my thigh and over the leg of my boxers. Then her finger wrapped around my shaft, taking me in her clutch whilst inching forward a fiddling causing her pussy to rub against my pubic mound as she gave a pleasurable moan of approval.

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

Her hand pumped up and down my tool a couple of fourth dimension before I felt a finger pinch down inside the fly of my boxers to lightly tickle my ball. I was immediately jealous of any boyfriend she ever had or would deliver knowing just how good she must be at this unhurt sex thing.

"Pinch my mamilla !"she said, looking me in the eye before closing hers to bask my hint. I lifted my hands to see her wonderful stiff buds and took each one between fingerbreadth and thumb, pinching gently. She ground her twat into me a lilliputian harder whilst continuing to rub my erection in her hot palm as I pinched and rolled her nipples between my digits.

She then moaned out brassy, 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 gasp escaped her back talk which, even with my lack of practical sexual knowledge, told me that she was having an orgasm.

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

I thrust up to receive her hand apparent movement adding to the pleasure of the pressure on her twat, not to mention my continued pinching of her nipples as we both rode our orgasm to an recherche climax, her manus continuing its rhythm method of birth control milking every last drop from me.

With our breaths still heavy, I let go of her boobs as she wiped her script against the stuff of my packer before leaning down close to me putting her sass to my ear. Her recollective blonde fuzz tickled my expression, not to note her pap now pressing against my own chest as I felt her warm breathing time on the face of my face.

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

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

"Mmm, looks like soul is already slap-up !"she said, peeling her lash from her body to feed me my first off scene of her Delicious looking pussy. She then picked up her bra and phone walking to my door and opening it."I reckon we still have a couple of hours before mum gets base so I'll text Shaun and tell him I have a head ache 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 lavatory .
