Step sisters pussy and my cock.

All my youth I fantasised about sex with women, I couldn't get these images out of my head.
It was like my desires were constantly wanting to be satisfied but they were always out of reach.
Then one Sunday afternoon my step sister aged seventeen suddenly came out of the bathroom wrapped in a towel.
“ what you looking at she said”
Freezing to the spot I gazed at her wet body replying “Not bad still needs work”
Knowing she is obsessed with how she looks she replied,
“ what the hell you on about, needs what work,”
“ maybe a little too much around the middle”.
That was it she flipped, “ fuck you I'm not fat if you think I'm fat then you have a small dick”
“Thanks for the compliment,” I said.
“ Yeah well men with small dicks aren't up to much”
“ ok well, girls with tiny tits have nothing between their legs,”
“Fuck you, my tits are fine and what I've got between my legs you could only dream of getting”.
“ yeah well with what I've got won't even go near what you've got trust me it would make you bloody scream if it ever did”.
“ oh you bloody think so do you” she said.
“ yeah and if those tits were much to look at I doubt there much to grab onto”. I said.
“ right if you think I'm not up to much and think I'm fat prove to me that your dick is something a woman would bloody want,”
“ what flash my dick at you, ok only if I get to see what you've got then we would both know now won't we,”.
“Right you little sod I'm not bloody shy, so come with me” she said.

With that she dragged me into her bedroom, closing the door she said,” Right let's see it, show me that tiny dick of yours”
What she didn't realise was I now had a bloody hard on, my dick now looked way bigger than normal.
So dropping my pants I let loose my clock, “They're tiny enough” “ Christ that's huge you bugger and hard”.
“Let's see what you've got,”
looking at her face she reluctantly dropped her towel, revealing a nice pair of tits with a nice bush tucked between her legs.
“Well, am I fat”. She said.
“ ok, am I tiny “?
“ no, I apologise it's bigger than my bloody boyfriends”.
“You not fat either better looking than I thought sorry I said what I did,”
“ god if you weren't my brother I would have that cock now”. She said.
“If you weren't my sister I would fuck you trust me”. I said.
“ I would let you as well, look Mom and Dad are out, looking at that dick it's about to explode, shame to waste it,”.
“ what you want me to fuck you,” I said
“ yeah, why not we aren't related”.
“Ok I won't be long either at this rate,”.
“Well don't rush I want it all,”.
With that she climbed onto her bed, opening her legs her nice pink open pussy eagerly awaited my still-solid cock, standing between her legs I slid up inside my step-sister for the first time.
The sensation felt amazing, she groaned loudly as I began to fuck her hole.
It wasn't long before I felt my cum rising up my shaft as she begged me to go faster, I held off as long as I could when she screamed at me to fuck her harder.
We both exploded together, my hot cum shooting deep into my step-sister's tight young pussy.
Holding it in for a while she looked up at me to say, “You bloody sod that was amazing, if never cum so fast.”
“ me neither you're well tight”.
“ god I needed that,” she said.
With that, she lifted herself onto her elbows to say,” If that's how you fuck then you can fuck me again, I best have another shower before they get home, keep this between us ok,”
Nodding I said, “When you fancy more of my dick let me know”.
After that afternoon we fucked regularly and my parents never found out.
