Brother and Sisters' sexual desires. R

When I was seventeen I started a sexual relationship with my sister, who was also seventeen.
It all started quite innocently one evening while our parents were out on one of their date nights.
They normally leave us home alone, but that night, I decided to go to my room early to play on my game console.
After about an hour I crawled into bed and was just about to drop off when I heard a loud thunderclap outside.
It was so loud that my sister who hated thunderstorms came running upstairs and thinking she would go to her room she instead came bursting into mine shouting “Move over will you I hate thunder”.
Throwing back my sheets she climbed in beside me, her warm body curled up next to mine in the spooning position.
Grabbing my arm she pulled it over her body and with her hand in mine she placed it tight against her breast.
Now my sister is not that slim but as she was only dressed in her nightgown and a pair of tiny briefs she pulled herself as tight as she could against me.
“ I hate it I really do,” she cried as the storm raged outside, each loud clap of thunder only encouraged her to hug me as tight as she could.
My hand still open and gripping her breast I could feel her nipple on my fingers, through her nightgown.
“ you do realise I’m holding your tit, sis,” I said.
“ I don’t care I just hate storms”
For a good half hour, I cuddled her body, as I was so close to her my cock started to twitch and stiffen, I couldn’t help it with me holding her breast and how close we were.
Eventually, the storm passed over, loosening her grip slightly I felt her nipple harden and my hand could then feel how plump her boob was.
“ I should let go sis” I said.
“ in a minute,” she said.
My cock not hard and pushing against her back she then pipes up, “You got a hard-on”
“ I can’t help it, I’ve been holding your breast for half an hour and what do you expect,” I said.
Turning to me she then for some reason reached behind her and grabbed my cock through my shorts, she felt how hard it had become.
“ god you are hard, can I see it,” she said.
“ what’s, my cock, why,” I asked.
“ I’ve never seen one hard, just curious,”
“ We can’t, I’m your brother,”
“ so I’m your sister, you’ve held my breast so it’s only fair I see your cock,”
Reluctantly I slipped my shorts down allowing her to see my stiff cock,
“ god you're dribbling,” she said.
“ yeah it does that sometimes, especially when it’s hard as it is,” I said.
Then she just reached forward and gripped it between her fingers, shocked at her action all I could do was watch her start to rub my cock.
“ is what the hell you doing,”
“ shut up will you I’m giving you a bloody hand job,”
“We can’t, you can’t, “ I said.
She just carried on rubbing my cock, her breasts wobbling under her nightshirt as she just went for it on my cock.
After a few minutes I knew what was coming and she also could tell by how hard I was getting, then I let out a low moan and a huge stream of cum shot from my cocks tip.
“ there you go, at least that works,” she said.
My stomach and her hand were now covered in my cum she picked up a cloth to wipe us both clean.
“ why did you do that,” I asked.
“ why not, you complaining,”
“ god no, you're pretty good at that,” I said.
“ my first time actually, read about how to do it thought I would see if I could do it”.
“ well you did,” I said.
Falling back beside me I noticed her gown had ridden up slightly, her blue Briefs showing a very obvious damp patch between her legs.
“Looks like I’m not the only one leaking” I said.
Lifting her shirt she nodded saying,” Well it does that sometimes when I get aroused,” said with a laugh.
“ so you're a bit aroused then after what you’ve just done to me,”
“ a little,” she said.
As I was still feeling the after-effects of my cum shot and how it was making me feel I then placed my hand on her inner thigh, thinking she would object her legs started to open slightly.
I could see her pants covering her pussy and how damp they looked.
Running my fingers up towards her wet pants I noticed she was just laid there eyes closed and seemed not to be bothered my hand was getting closer towards her open pussy covered pants.
I could see the shape of her slit through her briefs and how tight they were against her young pussy.
“ is that ok,” I whispered.
“ I’m not complaining am I,” she said.
My finger then started to trace the outline of the crease running up her blue pants.
That first touch made her gasp slightly as her pelvis lifted as my hand gently cupped her whole pussy between her wide open legs.
Her whole pussy felt warm to the touch as I started to rub my hand up over her now-wet crease.
She started to groan at my touch, my hand making her start to move in time with how I was caressing her pussy.
Then she lifted her backside, reaching down she quickly slipped her pants off, letting them drop beside the bed.
“ there you can touch me now,” she said.
Looking down at her pussy slit now in full view my finger slid down her lips over her tiny clit, hooking my finger I gently rubbed at her pussy as her lips parted allowing my finger to probe down towards her small entrance.
Again she gasped, and her legs fell open further as I slid my finger up inside her wet moist hole.
She gave out some soft low moans as each gentle prod of my finger seemed to reach inside her as she wanted me to.
“ god don’t stop, finger me please, go in further,” she begged.
I pushed in harder my finger now covered in her juices as her wetness increased with each push inside her.
Slowly pulling out and then slipping back in my hand firmly placed over her whole pussy with my middle finger wedged deep inside gopher virgin hole.
“Jesus Christ I’m cumming, don’t stop please don’t stop,” she cried.
With that, I felt my hand push in as hard as I could, she then placed her hand on top of mine to hold it in place while her orgasm wrapped through her young body.
Grunting at me her body seemed to stiffen and buck as I could feel her pussy clamp down on my finger.
After a few seconds, I felt her hand release mine, gasping and breathing heavily she seemed to return to normal.
“ my god that felt amazing, god I've not cum like that ever,” she said.
Collapsing back beside me, I slipped my fingers out of her pussy, her legs still wide open I watched her relax as her orgasm subsided.
“I love you,” she said.
“ I love you too,” I said.
Knowing what had just happened between I knew now that I could see my sister in a different light.
“ We shouldn't have done that you know,”
“ so I don't care, you enjoyed it and so did I,”
“If Mom and Dad find out we are dead,” I said.
“ They won't trust me they won't,”
At that one moment our sexual desires took over, and she reached down and grabbed my hard cock again, “ god it's a shame to waste that,” she said.
Not immediately thinking what she meant she stood up and slipped off her shirt. Fully naked she climbed on top of me.
Reaching under her body she gripped my cock and guided it towards her wet open pussy.
Feeling the heat on my cocks tip it found her open pussy, lowering herself down it slid up inside her with ease as she was already wet from her previous orgasm.
Her breasts now only inches from my face I felt for the first time my sister's warm pussy wrapped around her brother's cock.
I then took each breast in my hands and felt her hard pink nipples between my fingers.
She looked at me as she started to ride my cock, lifting up and down letting my whole hard shaft penetrate her as deep as she could.
With each drop of her body, I felt it slide in deeper, her hands on my chest and mine on her breast we just let the whole experience take over.
Then I shouted I was cumming, and she let out a cry saying she was too.
Then she dropped hard, my cock fully inserted and my cum shooting in her as much as I could.
Each pulse of my cock just seems to also feel her tight pussy clamp onto my stuff shaft.
We both came together, hard and fast and for the first time, we had sex, that forbidden taboo that brothers and sisters were never to have.
Lifting off me she again collapsed beside me, both looked at each other and didn't say a word.
We just let the moment pass as we both knew that what we had done changed everything.
Then it hit me, what if she gets pregnant, what if mom and dads find out?
We both just carried on as normal, but still that fear of not knowing if what we had done would come to light.
Then luckily a week later she got her period, the relief on her face and mine said everything.
She then later told me she had gone on the pill, which for us made it worse.
When our parents went on their next date night my sister called me to her room, opening her door she just laid their legs open beckoning me to fuck her.
Knowing she was on the pill and from that moment we started our intense sexual relationship.
Our parents never ever found out as we made sure they thought we hated each other.
