Bigger than Tommy's

It was quite late in the evening my parents was up stairs.. In their bedroom still enjoying live... My sister was upstairs sleeping she have school tomorrow... But not me I was downstairs in the living room watching terminator the box set 1-3.
My phone buzzed it was a tax message from my sister.
Asking if I was up!
Before I could answer she taxed me again. This time adding a photo...
It was a photo of her school outfit on the floor... With her white flowered panties on top of the school outfit ...
What can I say! My sister is very quick at taxing...
Repeating her first question! But this time adding the name of her boyfriend.
Tommy are you up! Yes or No
I replied back... Yes
Like I've mentioned my sister is very quick at taxing. She started sending photos getting more and more exciting... Then she stopped! It's no fun if you don't send me some photos back Tommy...
I was so horny I took a photo of my cock and send it to her..... She did not reply back.... I fucking shit myself all night...
I do not remember falling to sleep in the morning my dad woke me up... How was Terminator you look scared son... Come and get something to eat, me and your mum and sister had been waiting for you...
My mum and sister was in the kitchen mum was finishing off the breakfast. And my sister was eating and taxing and dad started to eat.. Dad looked at me and said eat up son... I said I felt sick I'm going to lie down... I was laying down when my sister came into the room... She jump on the bed looked at me and said; I want to see it it looked so big... Much bigger than Tommy's
