[A simple mistake on an online order form kicks off a fascinating tale of underage non-sex. If you have been reading my previous submissions, you should know by now that all the named characters in this story are real and capable of some of the fantasy events.]

Rapidly approaching puberty, Natalie was determined to discover her own sexuality, that of her school friends Alf and Charlie and all the adults attending the regular weekend family orgies.

Mum Steff and 19-year-old stepsister Nicki were always prepared to answer her most intimate questions, either across the breakfast table, at the nudist beach or just out in the garden where they loved to sunbathe naked. —- A delivery email pinged onto Nicki’s phone while eating breakfast in the Cardiff University student flat she shares with Molly, Chloe and Rach.

“Bugger, I must have ticked the wrong address on the Amazon order. The box of toys has gone to my home in Stockbridge. Look there’s the courier photo of Nat holding the box on the doorstep and she’s got nothing on. I’d better tell her not to open it.”

Nicki called her stepsister Natalie, “Hi babe, thanks for taking in my parcel from Amazon Prime. I hope you haven’t opened it. It should have come here.”

Nat replied, “It was just addressed to Ms Andrews. I thought the box was a bit big for the earbuds I ordered, but I signed for it anyway.”

Nicki, “so why were you naked in the photo?”

Nat, “Duh! I’d just got out of the shower when the doorbell rang. Mum and dad must have been busy in bed. Anyway I wasn’t actually naked,” lowering her phone to waist level, “It’s a towel”.

Nicki, “Yeah, but it doesn’t cover your little girly bits, sis.”

Nat, “I wondered why that courier spent so long getting the best photo of me holding the box. Said he was taking a few extra for his private collection - of course, I’ve no idea what he meant. Just what is Crisco?”

Nicki, “Oh bugger, you opened the box!”

Nat, “Yeah I had to check if it was the earbuds I ordered. It says Anal Lube on the jar - I know what it’s for, but why do you need so much? How many arses are you planning on fucking?”

Nicki, “Don’t be so crude! What flavour did they deliver?”

Nat, “it says Raspberry. Don’t tell me you plan on tasting it? That’s disgusting! Oh, there’s some other stuff in here- do you want me to take a look?”

Nicki, “No that’s fine, just put the box in my room. I’ll pick it up next time I’m home.”

Nat, “There’s this shiny showerhead. The instructions say it gives a deeply satisfying pulsating enema. I’ll have to ask Dad for a spanner.”

Nicki, “Don’t you dare...”

Nat, “You’re so easy to wind up. Wait a minute, what are these pink floppy things with nipples?”

Nicki, “fake tits, stupid! Now put the box away.”

By now, Nat was parading around the room with the silicone breasts stuck to her flat chest and the front of her sleep shorts stretched out around the artificial camel toe.

Nicki closed her eyes for a moment imagining how good they would look on the boy at Uni she was helping to transition but was dragged back to reality when the photo of a purple feeldoe arrived and Nat was innocently asking, “How do you use this, sis?”

Nicki, “Purple! I ordered flesh-coloured!”

Nat, “There’s a delivery note, they apologise for being out of stock of pink, so they’ve included a complementary bullet vibrator. Does that go in this hole?”

This exchange was followed by a long pause in which Nat apparently found out the answer to that question, herself.

Nicki, “You still there, squirt?”

Nat, “Yeah, I’m just watching the feeldoe video on their website. It said I had to be over 18, so I used your login.”

Nicki, “How...?”

Nat, “easy peasy. I’m using your old laptop. Now I know which end goes up your pussy and which end goes into the other girl. Oh, wait a minute. That’s a boy’s backside. I never realised you could fuck arses too.”

Nicki, now getting very worried about what else she might have left on that school laptop, “I’d rather you didn’t look in the Special Photos folder.”

Nat, “Wow, found it! You girls certainly know how to party. Is that Submissive Chloe on her knees, sucking your arse?”

Nicki, “bugger!”

Nat, “and that must be Rach suspended from the ceiling by her tits. That must really hurt and you can tell Molly she looks really hot in that black leather outfit, whipping those two blokes on the floor.”

Nicki, fearing further violations of the story no-masturbation-under-14 rule, “Please put the laptop away and stop looking at my sex toys.”

Nat, “OK, bye for now, but I might have to show Alf and Charlie what to expect when we’re all old enough.”

Two days later the same Amazon Prime courier delivered Nat’s earbuds, so she called Nicki again.

“You’ll never guess. I was properly dressed this time, but he was still looking at me a bit oddly when he took the photo. I pointed out that the last ones were probably unlawful and I might have to report him”

“You little minx. What did he say?”

“He said something crude about me not having any tan lines, you know, down there. I had to explain we always sunbathe in the nude, but that’s none of his business. He then agreed there must have been a mixup in the addresses and he would take your package back and deliver it personally to you in Cardiff.”

“That’s brilliant, thanks, sis. My ... uhh ... boyfriend will really appreciate that...”

“Sorry, sis. The dressing up wasn’t my idea. Emma and Ellie brought Charlie and Alfie over for a swim yesterday. Our three mums all stripped off and jumped in the pool, then dried each off in the sun.”

“I bet the boys were excited.”

“Yeah, no big deal. I’ve seen it all before of course, but Alf wanted to join in when they covered each other in suntan oil, but of course, we had to wear our swimming costumes.”

“Yeah, that no-nudity-or-sex-under-14 rule is a bugger!”

“Ahh, Charlie insisted on trying out my old shiny blue bikini with those silicone fake tits and a cameltoe piece to cover his tiny cock. She looked amazing, but Alf might have made a mess on them.” —-- The following afternoon, “Mum, you know I saw you eating out Aunty Emma and Aunty Ellie by the pool.”

Steff, “Yes darling, but you shouldn’t really have been watching. Why do you ask?”

Nat, “I wish someone would get me so excited that I came on her face. Charlie and Alfie are cute, but really haven’t a clue about sucking pussy.”

Steff, “so I would hope! You are all much too young to be even thinking about cunnilingus and orgasms. Oh wait a minute, what were you three up to in your bedroom?”

“No comment, mummy. As you say we’re all far too young to be trying out sexual gratification,” replied Nat, rubbing her crotch up and down her mother’s thigh.

A similar conversation was taking place across town between Charlie and his mum when she found the crossdressing photos on his phone.

“I can explain, Mum.”

Emma, “I think you’d better. I suppose Natalie put you up to this?”

“Yeah, she said Nicki had ordered these fake breasts and pussy for a boy at Uni and wanted to see what they looked like inside a real bikini. It was quite fun parading around her bedroom pretending to be a girl.”

“I hope that’s all you did. You know I only allow your dad to watch me having sex with other men, perhaps you’ll be a cuckold too when you’re old enough.”

Ellie is being watched by her husband Paddy and son Alfie giving an Intimate Massage to a male client passed on by Emma, in the Old Barn.

“Daddy, why does mummy have to wear tights with her Feeldoe? Is that to stop it slipping out?”

“Sorry son. We cannot possibly discuss this here. Now go to bed and keep both hands out of your PJs. We don’t want any more stained sheets.” —--- In Cardiff, Nicki reluctantly accepted the Zoom invitation from Nat, Charlie and Alfie wondering what they wanted.

“Hi, sis. It’s the middle of the afternoon, why haven’t you got any clothes on?”

Nicki had just finished an awesome session fucking her Amazon Prime courier, fortunately pulling out the sticky feeldoe before answering the call.

“Stop staring at my tits, you little perverts! What did you want? I’ve got a lecture in 15 minutes, so you’d better be quick.”

Nat grinned at her big sister’s discomfort, “You’d better wash that spunk off your belly first.”

Nicki was barely listening, absentmindedly dipping her fingers into the puddle and licking them clean.

“Heh, sis. I found your xvideos favourites on the laptop. 1578 of them! How did you ever find time for any schoolwork?”

Nicki, “I hope you haven’t watched any. Some are pretty perverted for three children even if you are all fully dressed.”

“Don’t worry, Nicki,” remarked Charlie, “it’s not like we’re going to copy any of the MMF porn. It’s just interesting to see what excited you at our age.”
