[26]f sister seducing teen bro on vacation. REAL STORY[fm]

Well my family parents and sis are arabs , but living in germany ,parents are a bit religious so hijab and so for females and u know .. muslim family.
Once we went on vacarion to sharam alshaikh to egypt , we had to share room me and my sis , i was still a teen , had kissed a girl before but nothing more .
I admit i always felt my sis had a bit of slutty soul in her but not infront of family .
So when we packed and so and went to our room first night tired ; i got to shower , got out and saw her naked changing clothes near her bed .
I was shocked cause she was just bending and her pussy was in vision from behind .
She saw me but no reaction .. so i went to bed .. hard as a rock . Put blanket on me and sneak peeked a little .. with a racing heart .
Could see her smiling but her back was to me .saw a bit of side boob . But i could tell she is hot af . Even hotter than the pornstars i watched at the time!!
We went to sleep that night . I waited till she slept and masturbated so hard thinking about what i saw and what am seing .
So woke up next day ,breakfast .. had our day .. thinking what the fuck happened and realising if she reacted so cold when i saw her naked it must be am just another one that saw her that way .
In night when we went back to hotel .. showered and so .. got out on my bed .. she was next in the shower i could hear her moaning very very softly like she didnt want me to hear but i heared and putted my ear on the door .
It was like she had to moan but stopping herself from being too loud .
When the shower stopped . I was so shocked about everything and went back to bed .. hard under my blanket just in a boxer .. she got out with only a towel .. went to her bed and got the towell off .. she was completly naked again now standing like her front to me seeing clearlyher boobs and pussy .
It was like shock . Horny af . And shy .
She looked at me but i couldnt get my eyes of her . But not looking in her eyes just glancing her body . Curvy fit .. big boobs .. pussy very clean . It was like what the fuck i almost cum without touching myself .. she shamelessly put her undie on smiling .. asked me what am planning we should do tommorow i didnt say a thing .. she started laughing .. told me its okay but dont tell anyone cause its forbidden but we love each other limitlessly right ..
I said right .. nodding .. still hard .. she started walking to me she told me i can touch her if i want .. without any word i touched her pussy .. it was very wett .. while am almost laying side ways on bed she got the blanket of me and got on her knees .. started carressing my inner thigh . Told me to take off my boxers .. my hard cock infront of her face .. she just started sucking ..
I was so thrilled i came a lot in 10 seconds in her mouth and she even didnt stop sucking .she spit the cum a bit on her boobs and a bit she swallowed .
Told me to promise i wont tell anyone and ill be very happy .i promised .. smiling for getting my first bj . “Confused smiling” .
She didnt even shower or saw .. she just wiped the cum and went to bed . I was tired .. like emotionally i fell asleep .
What happened the next 4/5 years before she got married to abroad . Is what made me a pro fuck machine. She taught me how to be a man .
