For newcomers who might like to catch up on the previous chapters, a quick summary follows.
On holiday in Devon with my parents and my brother Matt, we make friends with Abi and her daughter Sally. So begins a series of increasingly exciting sexual adventures.
•Chapter One - I accidentally stumble across Matt fucking Sally. Abi catches me watching them, and she masturbates with me while we both watch.
•Chapter Two - That evening in our bedroom, I tell my brother that I saw him with Sally. We each masturbate, and he ejaculates on my naked body.
•Chapter Three - The next day, I meet Sally on the beach while skinny-dipping and sunbathing topless, and we fuck.
•Chapter Four - That night, Sally asks me to film her and Matt fucking. Afterwards, they film me masturbating.
•Chapter Five - The next day, I meet Abi again. She watches me pee in the bath, and then I fist her.
•Chapter Six - That evening, I meet Matt in a pub garden and we watch the video of him and Sally fucking. Turned on, I give him a blow-job, and he fingers me until I orgasm.
Now read on...

I must have had a restless night, because when I woke up the next morning the top sheet was on the floor and I was sprawled naked on top of the bed with my legs apart, showing off everything I'd got. I smiled as I thought of Matt waking up and seeing me like that, and examined myself briefly for evidence of fresh semen, in case he hadn't been able to resist jerking off over my naked body. But as far as I could tell he hadn't indulged himself in that particular perversion. Maybe he was starting to run out of spunk at last.
I had a shower, and got dressed. For some reason, I was feeling especially horny already, so I decided to have a "no underwear" day. I slipped on an oversized t-shirt over my bare top half (I didn't want it to be too obvious that I had no bra on) and a summery skirt that was long enough to protect my modesty when I was sitting down (as long as I kept my knees together).
By the time I'd wandered downstairs, my parents and brother had almost finished breakfast. Mum and Dad announced that they were going to drive to the local cider farm to stock up with a few litre bottles before we went home. I perked up at this. Although I'd planned to go on the beach again, I'd recently developed a bit of a taste for proper cider, as opposed to the watered-down muck that's served in most English pubs outside the West Country. And I wouldn't be driving so there would be nothing to stop me sampling a few of the different brews that would hopefully be available to taste.
"I'll come too, if that's ok," I said.
My dad laughed. "Ok, just as long as you don't drink too much."
Matt rolled his eyes. "I'll stay here then," he said. "There's no point in me coming if I can't drink anything."
"You could try some of the apple juice," said my mum, though I knew she'd have let him have a taste of cider as well, under supervision.
"No thanks," he said. "I'll go on the beach instead. The surf doesn't look too bad this morning."
I suspected he was looking forward to getting Sally by herself, although it would be just his luck if she went off with her mum instead. But that was his problem.
"Well, don't stay in too long," said my mum.
"And don't drown," I added, and Matt stuck his tongue out at me.
"Do you need to get anything?" said my mum. She'd probably noticed I hadn't got a bra on, but I didn't think it was that obvious in my loose t-shirt, and besides, we weren't going anywhere posh. Anyway, she didn't always wear one herself: I'd definitely taken after her in the boob department. Small but perfectly formed, and well able to pass the pencil test.
