The flight arrived back in Sydney a few minutes early at 10:05 and they were all back home by midday, after more fond farewells and much thanking the parents for allowing the teens to have such an amazing holiday together. James received special thanks and kisses (from the girls) for all the upgrades and the sailing lessons.
The next few days were an anticlimax with the teens left to wash all of the dirty clothes while their parents went back to work. However, there were compensations as Mia and Tilly were still allowed to sleep with their boyfriends without restrictions until the end of the school holidays.
After a couple of days, when Jules arrived back from the university where she had been planning her lectures for the next term, Mia handed her a glass of white wine which she usually had when she returned from work.
“The holiday was so amazing!” Mia exclaimed. “I’m frightened I’ll wake up to find that it was all a dream.”
Jules chuckled. “It was real, alright! Exactly how many boys did you sleep with?”
“Mum! That’s private! But I’ll tell you if you tell me how many men you had sex with on New Year’s Eve at your swinging party.”
Jules looked shocked, but it gradually faded. “I suppose you had to find out sooner or later, but it’s been just the same 4 couples since uni. Are you upset?”
“That would be hypocritical, especially as I had sex with just as many boys on holiday. I was shocked when I first found out about you and Dad, but I got over it, especially since I joined the group.”
“The group?” Jules asked.
“Oops! I suppose I will have to tell you sooner or later, so here goes. It’s a secret, closed party group of nine couples plus Izzy. Everyone is between 14 and 17 and we have parties about every month, usually for someone’s birthday. We swap partners, but everyone has to use condoms, although all the girls are either on the pill or IUDs.”
“But you and Brett don’t use condoms?”
“No. As you know, Brett, Tilly, Nick and me all had STI tests before we had sex the first time, so none of us use condoms, even when we swap partners with each other. We’ve recently allowed Noah and Tammy, who’s in the year above me at school to join what Noah calls the Inner Circle. We’ve all sworn to use condoms if we have sex with anyone else, which we did on holiday.”
“So, if my maths is correct, you’ve had sex with 11 boys since October!”
“No!” Mia laughed. “So far, I’ve only had sex with boys in the Inner Circle and 2 on holiday.”
Jules chuckled. “So that’s only five boys then! Well, have fun but I can foresee a few potential problems arising. I hope it works out for you, but if you have any problems, you know you can always talk to me.”
“Yes Mum and thanks for being so understanding. We all know we’ve got a good thing going, so everyone seems to manage to sort out their issues amicably.”
“I have to admit to being a bit jealous that we never thought of your group idea when we were teens!”
“But you’re making up for lost time now!” Mia laughed.
Australia day was only a couple of days away, so Mia and Tilly were looking through Mia’s wardrobe, trying to determine what to wear for their Schoolgirl and Teachers themed party.
“Our school skirts are boringly long and Mum’s given all my old shorter ones to recycling.” Tilly grumbled.
“Why don’t we wear our tiny navy hockey skirts?” Mia suggested, getting hers out of the wardrobe and putting it on.
“Great idea!” Tilly replied, “but I’m not wearing the big navy sports knickers underneath, like we do for hockey.”
“Little white cotton panties might work” Mia said, swapping her black lacy ones.
“That looks great” Tilly said, “now, do you have an old blouse?”
Mia searched in a drawer and pulled out a thin white cotton blouse. “I had to stop wearing this one when my tits started to grow. It had also been washed so many times that the material was getting thin and Mum pointed out you could clearly see my nipples!”
She tried it on, fastening two buttons just below her breasts which were pushing the blouse apart to show a generous amount of cleavage and her nipples pushing against the material.
“That’s so sexy!” Tilly exclaimed. “Now just tie the loose ends together under your boobs.”
Mia did and Tilly exclaimed “Perfect!”
“Little white cotton socks or the black stockings we got for Halloween?” Tilly mused. “Why don’t you wear socks, cos you look more sweet and innocent than me and I wear the stockings for a tarty look and maybe I’ll forget the panties?”
Mia laughed and put the socks on, then her school shoes and finally her school blazer, leaving it wide apart.
Just then, Jules knocked on the door, having been told what they were doing.
“Come in, Mum” Mia shouted.
As soon as Jules entered and saw her sexy young daughter, she started laughing. “My little girl has turned into a sex goddess! Hold onto your knickers!”
“That wouldn’t be any fun!” Mia replied. “And Tilly’s not even planning to wear any!”
“Mia!!” Tilly exclaimed.
“Don’t worry” Jules said, laughing even more. “I won’t tell your mum.”
“She would just tell me to take a pair for later!” Tilly replied.
Jules left them to it and went downstairs.
“Tilly, I have to tell you that it sort of slipped out about the group when I was talking to Mum earlier, so I told her all about it and that we knew about their swinging parties. She was cool about it and I know she won’t share our private chat with your mum, but I thought you should know.”
“Thanks, I’ll tell my mum when it crops up, but I think she’ll be cool about it too. They can’t really say much when we know about their swinging.”
“I nearly forgot to tell you I had a Snapchat from Penny” Mia said, passing her phone to Tilly. The message read:-
“Thank you all for the wonderful first week of our holidays. We are now back home after our second week in Fuck-It! which was nowhere near as exciting as the first, at least for me. Tom’s new self confidence with girls helped him bed two Swedish girls in a threesome. He won’t tell me much about it as he says gentlemen never tell, but I checked his box of condoms and he’s used 8! My boyfriend badgered me for a blowjob as soon as we got back. I agreed providing he promised to eat my pussy after. He wouldn’t, so I didn’t! He told his group of friends and one I really have the hots for said he would, so now I have a new boyfriend. I’m working on Dad for a holiday in Australia next year - I’ll let you know how I get on. Give my love to the rest of the gang, love, Penny xxxxx”
On Australia Day, Mia and Tilly woke up with their boyfriends at the girls’ houses and both families went to the beach cafe for brunch before they all went on the Manly Ferry over to Sydney to join in the festivities. From Circular Quay, they walked past the Opera House and through the Botanical Gardens where they had lunch before going up to the Domain to listen to the folk bands. The whole harbour area was teeming with people celebrating together and making a great atmosphere.
When they all returned to Tilly’s house, everyone helped to prepare for the parent’s party in the evening. Once everything was ready, the girls went up to Tilly’s room to get ready for their own party. After showers, hair and makeup, they put on their sexy schoolgirl clothes. They then packed their overnight things and t-shirts and cut-offs for the morning and went downstairs. Their parents’ friends had arrived and they all made a big fuss of the girls, with lots of hugs.
Mark’s hug with Mia was a little more than platonic and Mia was quite shocked when he squeezed her bum whispering “You’re so sexy, Mia! I hope you’ll be joining our grown-up parties soon.”
At first Mia was too shocked to reply, but she had always had a crush on Mark, so she looked up into his eyes and replied “Me too!”
As usual, Mia’s dad, Rob took the girls to the party at Tammy’s, checking to see that they had gone inside the house before he left. They were greeted with hugs and kisses from their boyfriends.
“Girls, you’re the sexiest schoolgirls I’ve ever seen!” Nick declared.
“We should do a porn movie!” Brett added.
“Dream on!” Mia replied, but she was shocked when she realised that she was thinking it might be fun.
The boys took them into the kitchen to get drinks. Tilly noticed that Brett was pouring a particularly generous shot of vodka into their cokes.
“Are you trying to get us drunk?”
“No, but you may want to feel really relaxed tonight” Brett replied with a grin.
“And why would we want to be really relaxed?” Mia asked, suspiciously.
Brett just smiled and led them back into the lounge where all the group were assembled, admiring the girls’ schoolgirl outfits.
