My phone vibrated along with the sound of the tone to signal a substance 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 gens as the transmitter so decided to finish the net 90 seconds of play guessing that she was only abusing me in some way or was sending me a singular word picture 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 comptroller in my helping hand for the phone on the bed beside me.

I swiped the shield notification with my quarter round to give Chrissie's content and sat gawping at the picture that met my gaze.

I stared at the filmdom which was filled with a selfie impression of my baby in her underclothes wondering why the hell she had sent it to me. Despite her face not showing, I obviously recognised her bed, not to mention a familiar rucksack in the screen background so it was definitely her. I tapped on the next message and was met with another standardised pic, only this clip she had laid on the bed stretch over her shoulder to take a picture of her bum showing her thong disappearance between her afters bum nerve !

It occurred to me that she had more than in all probability sent them to me in erroneous belief 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 fault - and btw, who said u could borrow my Nike knapsack ?"

I hit ‘ send ’.

I laughed out flashy and imagined the look on her face when she realised she had sent the motion-picture show to me in fault and would no uncertainty be banging on my threshold shortly begging for me to blue-pencil them.

I brought the mental picture 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 Paraguay tea would comment on how good it must be to sustain such a ‘ baby'as an older sister living under the same cap. Of class I just shrugged it off, but without doubt it was certainly pretty damn near being her brother. We had always got on well together, having the usual sibling rivalry that tyke do, but being nearly 3 year honest-to-god than me she always went into ‘ protective'modality when she needed to, which was possibly even stronger now she was 21.

Not that seeing my sister in underclothes should really blow out of the water 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 in conclusion few months they had seemed to cut through up more as they saw me maturing quickly myself. Chrissie would even beleaguer me now and then when sure things popped up in conversation, but zip malicious. Being an athletic category we were all rather fit and active causing the odd put-on 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 response of saying it was definitely no big problem and one that I had started to harmonise with.

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

Dad would then move around behind her and turn over round to cup them himself saying ;"here, let me hold 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 have got 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 grateful for once that she had picked someone with a name 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 individual u hardly bang ?"I asked, sending my reply.

My screen lit up again ;"Thanks for the advice Steven, but I made for 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 doubt the jerky will show his married person anyway !"

"Eww, surely he'll observe 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 minutes before she replied making me enquire 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 great deal flesh ! Xx"

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

Shit ! Did I just admit to my baby that I wished I had seen her with less on than she already had ? I sat for a few minutes and thought about how I could rationalise without sounding like some pervy prowler now !

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

Holy fuck ! 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 tell me u harbour't sent that to him ?"

I looked at the pictorial matter again whilst waiting for her response and my god did it wait beneficial. I even zoomed in to see the grand nipple finding myself even admiring the artistic smell of the picture show from how the light hit her body. Her yummy looking tight consistence offset with garden pink ribbons and light-haired hair. I found I was aching now in my groin as my hammer pressed against my jeans.

"No Steven, don't panic, that was just for u for your variety business organisation 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 boob knowing full moon well it was for a delicacy to her piffling brother. I was already wondering how I could hide that movie away knowing it would probably give me enough jerk off ammunition for the side by side 50 twelvemonth !

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

"Of grade - 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 example to set ? Xx"she said.

"Sod the example, but what a hone dumbbell !"I replied.

"Thanks xx"came back.

"It matches the perfect bum"I said.

"U reckon ? 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 soft it would feel to have my script on it.

I have always been a bit of a jokester so on a whimsey decided to bare to my boxers and take a photo of my bum which I sent to Chrissie with the text ;"2 can play that game !"

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

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

I felt my eyebrow rise as I pondered the question. So obviously I took a moving picture of my own bare breast 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 accommodation in just my boxers with an erection pushing against the front led me to believe that perhaps I was in fact ‘ sexting'with my baby !

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

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

Chrissie replied ;"No, not wanted, but knowing your common sense of witticism wondered whether you would birth 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.

dogshit, she had shocked me again. Was she secretly hoping I would throw sent a pic of my own prick ? I considered having a spry search on the net for a moving-picture show of a huge knob to transport but instead found one of a cockerel bird, which obviously well-nigh people just call a peter, and sent that.

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

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

Suddenly there was a tap on my door 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 chasten position, closing the doorway behind her.

"Very funny !"she said, holding her phone up with the depiction 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 luck in the few seconds I thought I would get before she disappeared again, but instead, she just stood there.

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

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

"Yeah, something like that !"she said.

I gave her my better ‘ WTF'look and said,"Derrr, what essence did you think your amazing body would give on me ?"

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

"And ?"I asked.

"And I perhaps should throw known better !"she answered, now understanding properly."semen 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 hedge her appreciation. 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 small brother, let's see the hurt !"she said, making for another grab at my pillow.

Her wonderful perfumed smell met my nostril adding to the sight of her soused consistency causing my pot to go into overload, but I was still conscious I didn't want to depict off my naked penis !

I tried to dodge her again but she easily grabbed the boundary of the pillow and yanked it hard causing me to grip the other end as if now having a tug-of-war contender. But she was pretty strong and as much as I tried to continue it in front of my crotch, it was now waist summit 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 pillow fight causing me to recede my balance and decline on the bed.

Chrissie just laughed making me delight 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 imprint that her footling brother was growing fast. Then she tossed the pillow at my face which I used both hands to maintain myself with by catching it, giving her a seconds recreation which she used to straddle me, grabbing both of my carpus and pushing down onto the bed above my head.

I struggled slightly, but not quite as much as I could hold, and as the tumult subsided we found ourselves in a familiar position we have been in probably one C of times over the years, with one of us straddling the other holding their weaponry 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 face, Chrissie sat back slightly releasing some of the pressure on my wrists, but as she did so her arse perched nicely onto my jetty as I felt my erection nestle somewhere between her impudence ! 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 boxers as I felt ‘ cutis on pelt ’.

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

I stared straight in her eyes and nodded.

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

Her chest heaved and her grand earth glistened with a hint of sweat.

I felt a twinge in my cock as yet to a greater extent stemma rushed to it making it as pissed as I think I have ever known.

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

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

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

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

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

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

"Have you ever been with a female child ?"my Sister asked, as if changing the depicted object a little.

I shook my head.

"No tit gropes ?"she asked.

I shook my straits 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 breast in the build until the pic I sent you ?"she asked.

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

Chrissie pulled a boldness that said, ‘ true ’, before letting go of my carpus 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 knocker job at her young age, even though they are completely natural. They're just big, but the fact she is so sporty is the reason her bureau muscular tissue help keep them standing nice and pert, and my god, did they expect pert.

"Wan na feel ?"she whispered, rocking her body slope to side, making them jiggle. Of trend it also had the core of motion 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 wideness of my eyes gave away my answer.

I reached up, noticing my bridge player were shaking slightly before placing a ribbon over each breast. Nipples pressed against my hands as I spread my digit making it look like two flesh coloured spider were nestled on her tits.

And have it off me, did they feel courteous - just as voiced as I imagined.

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

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

She gave another movement, only this clock 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 weaponry were already by her slope to allow me memory access to her front, I suddenly felt fingers trace their way along my thigh and over the leg of my boxershorts. Then her fingers wrapped around my prick, taking me in her grasp whilst inching forward a petty causing her snatch to rub against my pubic knoll as she gave a enjoyable groan of approval.

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

Her paw pumped up and down my cock a couple of times before I felt a finger sneak down inside the fly of my boxers to lightly titillate my orchis. I was immediately jealous of any boyfriend she ever had or would have knowing just how serious she must be at this whole sex thing.

"Pinch my nipples !"she said, looking me in the eye before closing hers to enjoy my touch. I lifted my handwriting to see her wonderful stiff buds and took each one between finger and thumb, pinching gently. She ground her pussy into me a little harder whilst continuing to rub my erecting in her hot palm tree as I pinched and rolled her nipples between my digits.

She then moaned out forte, 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 lip which, even with my want of hardheaded sexual knowledge, told me that she was having an orgasm.

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

I thrust up to receive her script movements adding to the pleasure of the air pressure on her pussy, not to remark my continued pinching of her nipples as we both rode our coming to an exquisite climax, her hand continuing its calendar method milking every go fall from me.

With our breaths still heavy, I let go of her boobs as she wiped her hand against the material of my pugilist before leaning down close to me putting her sass to my ear. Her foresighted blond fuzz tickled my font, not to remark her nipples now pressing against my own thorax as I felt her warm breath on the side of meat of my face.

"There you go small brother, a treat for you, just from me"she whispered,"Now I'll leave you to make clean up your peck whilst I go and have a straightaway shower, but if you promise to delete those moving-picture show 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 first metre at my cum covered stopcock that was sticking out from my shorts. Just the Christian Bible 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 lash from her body to give way me my first position of her delicious looking puss. She then picked up her bra and sound walking to my doorway and opening it."I reckon we still have a couple of hours before mum gets household so I'll text Shaun and recite 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 .
