My new step-s****r Episode 1: Molly comes to stay

Hi, my name is Timothy, Mum had left years ago and Dad had to make do with internet porn, which I discovered on his laptop. He was something in IT, so had created me a user with 'parental controls', but his login had a really simple password "p0rn". One day I logged in to his account and gazed in amazement at the picture covering his desktop of two young-looking blonde naked girls lying by a pool. One appeared to have her right hand entirely inside the other girls cunt. Just below her bum on the screen was a folder named 'fisting', which revealed dozens of downloaded photographs of these two girls stripping off each others bikinis, kissing, fondling breasts and then fisting. One girl rubbed suntan oil all over the others breasts, tummy, thighs and then pussy, until it was running down her arm and dripping off her elbow. In one photo she had bunched her fingers together and pushed them half-way into the girls pussy, and they both smiled provocatively. At this point I heard dad returning from the garden so hurriedly shut the laptop and tried to hide the sticky mess in my pants.
One night I couldn't sl**p so tip-toed downstairs into the lounge behind the sofa to see dad not wearing much, talking to a web-cam picture of a gorgeous naked lady on his laptop. She was slowly squeezing her nipples, licking her lips and discussing what she would do to dad at the weekend. I crept back to bed and made do with a girly mag I found in dad's sock drawer.
She arrived on Friday, and dad announced this was my new step-mum who had come to stay for the weekend, bringing her bossy daughter Molly, who said she was 15. Molly was really cute – short dark hair, a lovely smile, small tits in a tight tee-shirt and long legs emerging from a short skirt. We were lying in the garden when I told her about the photos on dad's laptop, and nervously asked if she had ever fisted.
"How did you know I was a lesbian" she murmured.
"My best mate at school reckons all pretty girls are bi-sexual, so I figured you might have tried it".
"No" said Molly, stroking my right hand and checking for short finger nails "but show me the pictures, and we might give it a try".
We sauntered indoors, trying to hide our blushes, grabbed the laptop and ran upstairs to Molly's room. I showed her how to logon and stroked her bottom while she flipped through the pictures lying face-down on her bed. She was rubbing up a damp patch on the front of her panties when she spread her legs wide enough to allow me to touch her cunt. Flipping over onto her back she pulled off the damp panties and f***ed my tongue hard onto her clit. When I came up for air she had lifted the tee-shirt and was squeezing her nipples, just like her mum on the web-cam.
"There's some baby oil over there, you need lots on your hand".
I grabbed the bottle off the cupboard and coated my right hand before dropping my shorts and squatting down between her thighs and pushing one then two fingers into her sopping cunt.
"More fingers" she moaned "harder" then "…aarghh".
Afterwards she told me she had been climaxing from the second finger to the full fist.
Bending down she wrapped her damp panties around my willy and jacked me off, while I tried to lick her neck and then chew on a breast. She roughly pushed me away, straightened her skirt and tee-shirt and flounced off downstairs. I hid the sticky sodden panties, got dressed and put the laptop back in its usual place downstairs.
At tea Molly acted as if nothing had happened, but smiled when her mum asked if we were getting on OK, and flashed her bare pussy at me and dad.
Molly explained that she had been born when her mum was only 15, so they grew up more like s****rs than mum and daughter, and had always had a very open sexual relationship – sl**ping together and with mum's girlfriends when Molly was growing up.
So I was not too surprised when that night Molly f***ed me to watch her mum bouncing up and down on dad's prick, while she straddled his head and rubbed her cunt back and forth across his nose and chin. As they were facing each other across his chest they kissed and squeezed each other's breasts before climaxing noisily.
The following week we all went shopping to Primark to buy Molly a whole pack of shiny black thongs, a new bikini and a really short skirt. Molly and her mum disappeared into the changing room to try them on and were gone for a good ten minutes. They walked back rather oddly giggling, dad paid for the clothes and we headed for the car park.
“Are you alright” I whispered to Molly; she just chuckled and said “You’ll see when we get home” and stroked the back of her tiny shorts.
On the way home Molly sat in the front seat with dad’s hand down the front of her shorts and her mum sat in the back with me, stroking my willy with her moist panties. As soon as we got home, Molly pulled off her shorts and bent over the sofa dad tugged on the purple ring hanging from her bum and pulled out the anal beads that her mum had inserted in the changing rooms. I managed some really close photos of Molly’s enlarged bum hole before dad blocked my view by squeezing in the tip of his enormous penis. Molly screamed as half the length slid in; Molly’s mum licked his balls and dad groaned and came quickly, dropping his prick into her mouth. Shakily I shot the cum dripping from Molly’s bum and running down her legs, and then her mum licking it all better.
Next day dad had to go up north on a contract and left with a laptop full of photos of Molly and her mum, waiting for Episode 2.
