My headphone vibrated along with the sound of the pure tone to indicate a message 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 name as the sender so decided to finish the last 90 sec of play guessing that she was only abusing me in some way or was sending me a funny mental picture she had found on the net.
As the last few bit counted down my earpiece went again indicating a second message from her too.

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

I swiped the riddle notification with my thumb to give Chrissie's message and sat gawping at the picture that met my gaze.

I stared at the screen which was filled with a selfie picture of my sister in her underclothes wondering why the the pits she had sent it to me. Despite her grimace not showing, I obviously recognised her bed, not to mention a familiar rucksack in the backcloth so it was definitely her. I tapped on the following message and was met with another similar pic, only this meter she had laid on the bed stretch over her shoulder to make a picture of her bum showing her thong disappearing between her odoriferous tush face !

It occurred to me that she had more than than belike 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 fault - and btw, who said u could adopt my Nike rucksack ?"

I hit ‘ send ’.

I laughed out loud and imagined the look on her facial expression when she realised she had sent the moving-picture show to me in error and would no doubt be banging on my door shortly begging for me to delete them.

I brought the pictures back up on silver screen to look up to the sight, despite them being of my own sister. But there no denying she was hot, as all my mates would remark on how skillful it must be to have such a ‘ baby'as an former sister living under the like roof. Of course I just shrugged it off, but without doubt it was certainly pretty damn unspoilt being her Brother. We had always got on well together, having the common sibling competition that youngster do, but being nearly 3 geezerhood 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 underwear should really shock me because I was used to her, and mum too come to think about it, walking around the odd time in their bloomers and bra, although the cobbler's last few month they had seemed to cover up more as they saw me maturing quickly myself. Chrissie would even tease me now and then when certain matter popped up in conversation, but naught malicious. Being an athletic category we were all quite fit and fighting causing the odd jocularity now and then as both mum and Chrissie always said they had the unfortunate affair 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 accord with.

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

Dad would then move around behind her and reach 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 mistake cos they should make 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 public 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 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 dubiety the jolt will present his better half anyway !"

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

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

There was a few hour 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 anatomy ! Xx"

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

diddley ! Did I just admit to my sister that I wished I had seen her with LE 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 probability to reply with a message from her ;
"You mean like this ? Xx"she put, and sent a word-painting of her laid on her spinal 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.

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

I looked at the photo again whilst waiting for her response and my god did it depend unspoilt. I even zoomed in to see the marvelous tit finding myself even admiring the artistic spirit of the pictorial matter from how the luminousness hit her eubstance. Her delicious looking tight trunk offset with pink palm and blonde haircloth. I found I was aching now in my groin as my shaft 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 place piece of tail ! My own sis had sent me a pic of her own boob knowing entire well it was for a treat to her little brother. I was already wondering how I could hide that image away knowing it would probably pay me decent wanking ammunition for the next 50 twelvemonth !

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

"Of row - 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 representative, but what a perfect boob !"I replied.

"Thanks xx"came back.

"It matches the unadulterated bum"I said.

"U call up ? Xx"she replied.

"dirt, deffo sis, u must surely cognize 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 depiction again, wondering just how soft it would finger to make my hand on it.

I have always been a bit of a joker so on a whim decided to leach to my boxershorts and lease a characterization of my bum which I sent to Chrissie with the textual matter ;"2 can play that game !"

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

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

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

I could hardly trust I was having this weird ‘ texting'conversation with my sis, or should that be ‘ sexting'? The fact I was now standing in my chamber in just my boxers with an hard-on 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 curious as I was worried your pic might have been lower ! Xx"

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

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

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

"STEVEN ! Stop gasconade ! 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 quick search on the net for a picture of a huge pommel to send but instead found one of a cockerel Bronx cheer, which obviously to the highest degree people just phone a pecker, and sent that.

I think I laughed out tatty 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 bulwark with my raging hard-on.

Suddenly there was a tap on my doorway which was then opened before I had probability to shout out either ‘ come in'or ‘ hold on'and Chrissie appeared, in her underwear, albeit with her bra back in its discipline lieu, closing the door behind her.

"Very suspect !"she said, holding her telephone up with the picture of the raspberry 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 opportunity 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 considerably ‘ WTF'looking at 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 take in known well !"she answered, now understanding properly."Come 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 elude her appreciation. Her titmouse bounced seductively as she reached forward which made for a lovely view despite the fact I was trying to get out of her way.

"Come on piddling buddy, let's see the scathe !"she said, making for another grab at my pillow.

Her wonderful perfumed smell met my anterior naris adding to the mickle of her tight body causing my mother wit to go into overload, but I was still conscious I didn't want to show off my defenseless phallus !

I tried to sidestep her again but she easily grabbed the sharpness of the pillow and yanked it gruelling causing me to spellbind the early end as if now having a tug-of-war competition. But she was pretty strong and as much as I tried to keep it in nominal head 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 pillow engagement causing me to suffer my balance and fall on the bed.

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

She looked down at me, her eyes appraising my eubstance as if move that her trivial brother was growing fast. Then she tossed the pillow at my face which I used both paw to defend myself with by catching it, giving her a endorse diversion which she used to straddle me, grabbing both of my wrist joint 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 position we have been in probably hundreds of times over the years, with one of us straddling the early holding their blazon 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 insistence on my wrists, but as she did so her arse perched nicely onto my seawall as I felt my hard-on nestle somewhere between her cheek ! I also knew instantly that with the transactions wrestling we had done, my pecker had come through the fly-hole at the front of my boxers as I felt ‘ tegument on peel ’.

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

I stared straight in her eyes and nodded.

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

Her thorax heaved and her grand Earth glistened with a tip of sweat.

I felt a twinge in my cock as yet to a greater extent blood rushed to it making it as stiff 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 certain it would be any to a lesser extent stymie now. But she then moved again, her bum cheeks rubbing me and for a secondment 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 minute ?"she asked.

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

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

"Have you ever been with a girl ?"my sis asked, as if changing the subject field a little.

I shook my head.

"No titty gropes ?"she asked.

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

I shook my nous again, but added that technically, that wasn't in the human body as it was a photograph so I still hadn't !

Chrissie pulled a face that said, ‘ true ’, before letting go of my wrists 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 cancel. They're just big, but the fact she is so gaudy is the reasonableness her pectus muscles help hold them standing nice and impertinent, and my god, did they search pert.

"Wan na sense ?"she whispered, rocking her body side to side, making them jiggle. Of path it also had the effect of apparent movement down below too, but for some reason the concentration I was showing on her tits made me a small less desperate to cum.

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

I reached up, noticing my hands were shaking slightly before placing a palm over each breast. Nipples pressed against my bridge player as I spread my finger's breadth making it count like two flesh coloured wanderer were nestled on her tits.

And have it away me, did they feel nice - just as indulgent as I imagined.

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

"And by the way,"she said,"from the feel against my buns 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 time pushed back and forth a couple of sentence indicating exactly what she meant.

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

As her arms were already by her side of meat to allow me admission to her front, I suddenly felt fingers trace their way along my thigh and over the leg of my boxers. Then her fingerbreadth wrapped around my shaft, taking me in her grasp whilst inching forward a little causing her pussycat to rub against my pubic mound as she gave a pleasurable moan of approval.

It hit me that she was getting her own pleasance from this slight meeting from the spirit on her face, and who was I to botch her fun ? !

Her hand pumped up and down my cock a brace of times before I felt a finger abstract down inside the fly of my shorts to lightly tickle my balls. I was immediately jealous of any boyfriend she ever had or would have knowing just how beneficial she must be at this wholly sex thing.

"Pinch my pap !"she said, looking me in the eye before closing hers to delight my touch. I lifted my hands to see her grand stiff buds and took each one between finger and ovolo, pinching gently. She ground her kitty-cat into me a slight harder whilst continuing to rub my erection in her hot palm as I pinched and rolled her nipple between my digits.

She then moaned out loud, a groan that I took to be of pleasance rather than trouble moving herself faster on top of me. Then I felt her chill as a brassy gasp escaped her backtalk which, even with my lack of practical sexual noesis, told me that she was having an orgasm.

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

I thrust up to meet her hand movements adding to the pleasance of the imperativeness on her pussy, not to mention my continued pinching of her pap as we both rode our coming to an keen orgasm, her hand continuing its rhythm milking every end drop from me.

With our breaths still heavy, I let go of her pinhead as she wiped her hand against the textile of my shorts before leaning down close to me putting her sassing to my ear. Her long blonde hair tickled my typeface, not to mention her nipples now pressing against my own chest as I felt her fond hint on the side of meat 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 promptly shower, but if you promise to delete those exposure then I'll let you fuck me later if you would wish ?"she added.

She lifted herself from me and sweep her leg over mine as she got off the bed, looking for the first meter at my cum covered cock that was sticking out from my short pants. 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 thong from her physical structure to give me my number one view 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 hours before mum gets home so I'll text Shaun and narrate 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 underworld had just happened as she headed for the privy .
