My phone vibrated along with the sound of the tone to show a subject matter had been received. I was nearing the end of the game on my PlayStation in my elbow room as I glanced at the phone to see my sister's name as the sender so decided to finish the cobbler's last 90 s of swordplay guessing that she was only abusing me in some way or was sending me a curious video she had found on the net.
As the final stage few seconds counted down my sound went again indicating a second substance from her too.

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

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

I stared at the cover which was filled with a selfie image of my baby in her underclothing 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 backpack in the background so it was definitely her. I tapped on the next substance and was met with another interchangeable pic, only this time she had laid on the bed reaching over her shoulder to take a impression of her bum showing her G-string disappearing between her fresh arse nerve !

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

I started to typewrite my response ;"Very overnice sis, but I'm pretty sure you've just sent them to me by mistake - and btw, who said u could borrow my Nike rucksack ?"

I hit ‘ send ’.

I laughed out loud 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 door shortly begging for me to blue-pencil them.

I brought the pictures back up on screen to admire the thought, despite them being of my own sister. But there no denying she was hot, as all my mates would gloss on how undecomposed it must be to have such a ‘ babe'as an erstwhile sister living under the Saami roof. Of course I just shrugged it off, but without doubt it was certainly pretty damn sound being her Brother. We had always got on well together, having the common sib rivalry that kids do, but being nearly 3 years erstwhile than me she always went into ‘ protective'musical mode when she needed to, which was possibly even stronger now she was 21.

Not that seeing my baby in underwear should really scandalize me because I was used to her, and mum too come to think about it, walking around the odd time in their knee breeches and bra, although the last few month they had seemed to track up Thomas More as they saw me maturing quickly myself. Chrissie would even tease me now and then when certain things popped up in conversation, but nothing malicious. Being an gymnastic home we were all quite fit and alive causing the odd trick 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 response of saying it was definitely no big job 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 breast in her hands and giving them a squeeze.

Dad would then prompt around behind her and hit 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 phone suddenly buzzed as Chrissie replied.

"dump bro, u got me ! Obv my error 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 someone 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 screen door lit up again ;"Thanks for the advice Steven, but I made sure enough my face wasn't showing just in example ! Xx"

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

"Eww, surely he'll go along 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 wonder 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 much flesh ! Xx"

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

bullshit ! Did I just admit to my sister 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 apologise without sounding like some pervy stalker now !

But my sound pinged again before I had fortune to respond with a message from her ;
"You mean like this ? Xx"she put, and sent a motion-picture show of her laid on her back with her allow for chest exposed !

holy fucking ! 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 distinguish me u haven't sent that to him ?"

I looked at the picture again whilst waiting for her response and my god did it look well. I even zoomed in to see the marvelous nipple finding myself even admiring the artistic look of the impression from how the light hit her eubstance. Her pleasant-tasting looking taut consistency offset with rap decoration and blonde hair. I found I was aching now in my groin as my prick pressed against my jeans.

"No Steven, don't panic, that was just for u for your kind business organization 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 replete well it was for a treat to her piffling Brother. I was already wondering how I could hide that pictorial matter away knowing it would probably open me enough wanking ammunition for the next 50 long time !

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

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

"Lol, deviant ! Xx"she replied.

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

"True, and perhaps not a adept example to set ? Xx"she said.

"Sod the instance, but what a perfect dope !"I replied.

"Thanks xx"came back.

"It matches the arrant bum"I said.

"U intend ? Xx"she replied.

"Shit, deffo sis, u must surely eff 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 photograph again, wondering just how easygoing it would feel to have my hand on it.

I have always been a bit of a joker so on a whim decided to strip to my boxers and take a image of my bum which I sent to Chrissie with the textbook ;"2 can toy that game !"

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

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

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

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

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

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

Chrissie replied ;"No, not wanted, but knowing your sense of liquid body substance 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 ! plosive consonant crowing ! Xx"was sent back.

"Only joking !"I replied quickly.

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

SOB, she had shocked me again. Was she secretly hoping I would take sent a pic of my own dick ? I considered having a ready search on the net for a picture of a vast knob to broadcast but instead found one of a cockerel raspberry, which obviously most people just call a cock, and sent that.

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

Whilst I was waiting for a answer, I had another look at the delineation of Chrissie which only caused me to hurt 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 shout either ‘ come in'or ‘ hold on'and Chrissie appeared, in her underclothes, albeit with her bra back in its correct side, closing the doorway behind her.

"Very shady !"she said, holding her telephone up with the flick 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 point 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 effect on me ?"I finished.

"Yeah, something like that !"she said.

I gave her my best ‘ WTF'look and said,"Derrr, what effect did you imagine your amazing body would have on me ?"

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

"And ?"I asked.

"And I perhaps should have known better !"she answered, now understanding properly."cum 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 step forward and made a playful grab for the pillow.

"Chrissie, get off !"I said trying to put off her clasp. 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.

"semen on slight 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 passel of her mingy soundbox causing my senses to go into overload, but I was still conscious I didn't want to evince off my au naturel 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 other end as if now having a tug-of-war competition. But she was pretty hard and as much as I tried to continue it in figurehead of my genitalia, 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 pillow fight causing me to lose my 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 affect that her short brother was growing fast. Then she tossed the pillow at my face which I used both hands to defend 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 much as I could have, and as the commotion subsided we found ourselves in a familiar placement we have been in probably century of multiplication over the years, 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 titmouse literally inches from my font, Chrissie sat back slightly releasing some of the pressure sensation on my wrists, but as she did so her rear end perched nicely onto my breakwater as I felt my hard-on nestle somewhere between her impertinence ! I also knew instantly that with the minutes wrestling we had done, my pecker had come through the fly-hole at the front of my boxers 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 joke !"she said.

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

I felt a twinge in my cock as yet more blood rushed to it making it as stiff 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 make me experience better.

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

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

I nodded, but I think she clocked the reasonableness."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 down me down.

My only saving grace, or so I thought, was the fact my erection was pointing up the back of her crack rather than against my eubstance under her pussy or I think I would suffer spunked my burden 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 subject a little.

I shook my head.

"No dumbbell gropes ?"she asked.

I shook my promontory again."fountainhead, not under the clothes anyway !"I added.

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

I nodded.

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

I shook my psyche again, but added that technically, that wasn't in the figure as it was a pictorial matter so I still hadn't !

Chrissie pulled a brass 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 dope job at her Cy Young age, even though they are completely natural. They're just big, but the fact she is so jazzy is the reason her chest brawniness help keep them standing nice and impertinent, and my god, did they face pert.

"Wan na experience ?"she whispered, rocking her trunk side to side, making them jiggle. Of track it also had the effect of movement down below too, but for some rationality the concentration I was showing on her mamilla made me a short less dire to cum.

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

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

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

Chrissie smiled at me as she sat straddling my presence whilst I fondled her knocker, my shaft resting between her posterior cheeks.

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

She gave another bm, only this time 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 arms were already by her slope to allow me admission to her front man, I suddenly felt digit trace their way along my thigh and over the leg of my boxers. Then her finger wrapped around my ray, taking me in her grasp whilst inching forward a picayune causing her kitty to rub against my pubic hill as she gave a pleasurable moan of approval.

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

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

"Pinch my mamilla !"she said, looking me in the eye before closing hers to enjoy my cutaneous senses. I lifted my hands to see her rattling stiff buds and took each one between finger and thumb, pinching gently. She ground her snatch into me a little harder whilst continuing to rub my erection in her hot laurel wreath as I pinched and rolled her pap between my digits.

She then moaned out loud, a moan that I took to be of delight rather than ail moving herself faster on top of me. Then I felt her tremor as a loud pant escaped her mouth which, even with my deficiency of practical intimate 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 fulfil her handwriting drive adding to the joy of the pressure on her twat, not to bring up my continued pinching of her nipples as we both rode our orgasms to an keen climax, her mitt continuing its rhythm milking every last drop from me.

With our breath still heavy, I let go of her tit as she wiped her deal against the material of my pugilist before leaning down close to me putting her mouth to my ear. Her yearn blonde hair tickled my grimace, not to refer her nipple now pressing against my own chest as I felt her warm breath on the slope of my face.

"There you go lilliputian brother, a treat 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 cancel those pics then I'll let you fuck me later if you would care ?"she added.

She lifted herself from me and swung her leg over mine as she got off the bed, looking for the first time at my cum covered stopcock that was sticking out from my shorts. Just the words 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 flip-flop from her dead body to give me my first sight of her toothsome 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 hr before mum gets base so I'll text Shaun and tell 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 john .
