my sister’s little secret

Let me throw some little information about myself first.
I am 18 years old, tall person and my sister is 21, my main language isn’t english so forgive me for my spelling mistakes

it all started years ago when I was about 11 years old and my sister was 14 years old.
she was already got in puberty and she had large C cups breasts that you would love to play with for hours with big round nipples.

it all started one night we were alone in the house and bored, my parents were out for a wedding and they usually get back home at around 12am at midnight.
so we usually play a game called houses where she would be the wife and I’m the husband
we pretend to do simple stuff like going to work and she would cook for me like normal husband and wife do.
so I was pretending I got back from work and she came to me and kissed me on the cheek.

so I said
“hey what are you doing that’s disgusting, dont you kiss me”

“but you have soft cute cheeks” she said

“still I don’t like being kissed!”

“well that’s not fair, in the game we are married and that’s what married people do!”

“yeah I guess but kissing is really weird” I said

“you should try kissing on the lips like mummy and daddy do when we are not looking”

all of the sudden she came to me holding my hands and pushing her body into mine and starting kissing me on the lips

I struggled for a few seconds but when I tasted her lips on mine I loved it and I liked the feeling of her body against mine

seconds later she became so wet and horny you can smell her lust in the air,she started to dry humping me and putting her tongue in my mouth, I reached under her shirt feeling all her warm body
untill I grabbed her tits and started playing with them and feeling them , she saw I was enjoying her boobs so she took off her shirt and I had a big erection sucking on her tits and dry humping my penis on her wet pussy

I went to reach under her pants for her ass but she wouldn’t let me.
