Mia joined her parents tidying and cleaning the house before their guests arrived. Mid-afternoon, the grandparents arrived first, closely followed by her dad Rob’s sister, her husband and their daughter, Emma, 13. There was lots of hugging and noisy chatter as they had not seen each other for a while. Eventually, Mia led Emma upstairs with her bag and into her bedroom.
Immediately, Emma noticed two photos on Mia’s dressing table. One was of Brett on the beach, dressed in just his board-shorts, holding his surfboard.
“Wow! He’s a hunk! Is he your boyfriend?” Emma asked.
“Yeh, Brett. Since a couple of months ago” Mia replied with a big grin.
“Have you slept with him yet?”
“Emma! You’re so nosey!” Mia replied, blushing.
“I know, but your blush proves it!”
“Do you have a boyfriend?” Mia asked, to stop Emma asking any more detailed questions.
“Yeh, we kiss and stuff but I haven’t let him go any further yet. Anyway, I’m not on the pill and I don’t trust condoms. What do you use?”
Mia thought that this conversion was getting very personal, very quickly.
“I have an IUD. Now, do you want to unpack your bag, so we can hang your stuff up to hang the creases out?”
“Yeh, thanks” Emma replied, pulling out a couple of dresses and some tops. She passed them to Mia who put them on hangers in her wardrobe.
“Where can I put shorts, bikinis and panties?” Emma asked.
“The bottom drawer of the chest of drawers is pretty empty” Mia replied, immediately realising her mistake. “On second thoughts...”
But it was too late. Emma had already pulled the drawer out and gasped.
“There’s boys stuff in here! A toilet bag with mens’ stuff, boxers and things!” Slowly it dawned on Emma. “Mia! Do your parents let him stay the night!?”
Mia sighed. “Yes, but please don’t tell your mum and dad.”
“Wow! OK” Emma replied, thinking this would be good ammunition when the time came to ask her mum if her boyfriend could stay the night. She could say that her cousin was allowed.
“Would you like to go down to the beach for a quick swim?” Mia asked. Emma lived inland so did not get the opportunity often.
“Cool!” Emma replied.
Mia texted Tilly, asking if she wanted to join them.
Mia and Emma changed into bikinis, Mia putting on her tiny black string bikini and Emma putting on one which covered a lot more.
“Wow! Your bikini is tiny!” Emma exclaimed. “I wish Mum would allow me to have one like that.”
“Well, I’ve got a similar one to this in pink, if you’d like to borrow it while you’re here” Mia offered. “If you always wear a t-shirt when we leave and put it on when you get back, your mum will never know.”
“Thank you! Thank you!” Emma squealed, stripping.
Mia had noticed that Emma’s boobs were already about the same size as her’s, so was not surprised when the bikini fit perfectly.
“You look so hot, Emma!” Mia exclaimed.
“Wow! I do, don’t I. I wish Jake, my boyfriend could see me in this!”
“When we get to the beach, I’ll take some photos with your phone, then you can send him one.”
“Let’s go then!” Emma said, pulling on a t-shirt after they had both applied sunscreen.
The t-shirts came off as soon as they reached the beach and they both noticed a few boys checking them out. They went for a swim and were soon joined by Tilly and her younger cousin, Will who was 13. Tilly and Mia introduced their cousins who seemed to have an instant attraction, much to Tilly and Mia’s amusement.
The next day was Christmas Eve which involved lots of present wrapping, but Mia was excused helping in the kitchen now that her aunt was helping. She was told to keep Emma entertained, so she spent most of the day teaching Emma to surf. She also coordinated this with Tilly who brought her cousin Will along. He and Emma spent most of the day flirting shamelessly.
In bed together that night, Emma asked “Mia, I think Will might kiss me soon, so could you give me some tips?”
Mia laughed “OK. The first thing is not to bash noses, so tilt your head a bit to one side and slowly move closer, all the while looking into his eyes, smiling while you purse your lips, but not too obviously.”
Emma followed her instructions and Mia said “Good, but be careful not to overdo it. There’s a fine line between ‘Kiss Me’ and ‘Fuck Me’. If he hasn’t got the message that you like him by now, he’s probably gay. Now, keep your lips slightly apart as they meet his and be prepared for his tongue to slide between your lips. Suck it in gently to show you want it.
Emma practised on her arm, really getting into it.
“Wow!” Mia exclaimed, laughing. “Now you’ve made it obvious you like him. Remember, he’s a guy and their brains are hard-wired to try and get you excited enough so that you let them take off your panties and fuck you. So when he makes his first move and starts to feel you up, you have to decide if you want to let him. If you do, he might take it as a green light to move up to third base, so don’t be surprised if his hand slips down to your leg and starts to slide up towards your panties. It would be best to keep things above the waist at your age but don’t go all sulky and moany if you want him to stop. Something like ‘That’s too nice, but I’m not ready for that yet!’.”
Emma spent the next half hour practising, before falling asleep.
On Christmas morning, Mia woke up first and put her arm around Emma and was about to kiss her when she realised that it was not Tilly or Brett in bed beside her.
They showered and joined their parents and grandparents for breakfast, after which they opened their Christmas presents. Mia got a new iPad from her parents, a new school bag filled with the bits and pieces her mum had told her aunt she needed and a bank transfer confirmation for $100 from her grandparents. Emma got her first phone, a similar school bag from her aunt and uncle plus a bank transfer confirmation from her grandparents.
