Luke sat in the cafe at the shopping mall with his mum, drinking hot chocolate while they were waiting for his aunt Jenna. She had married his mum's brother just a few months earlier and she had invited him to come to her lake house to spend some time with her and her twin daughters Mia and Emma. This way, they would get to know each other and his parents could spend some quality time as well.
Although Luke was eighteen, his mum still treated him like a boy. He was short and skinny but an adult none the less.
"Please don't cause aunt Jenna any headache Luke," his mum said, "be a sweetheart and behave yourself!"
As if he ever did anything naughty!
"Yes mum, I'll be fine."
He was looking forward to spending time with his new relatives. They seemed a lot more relaxed than his mum and dad, not that this was much to go by.
Finally, Jenna and her daughters arrived, giving them both long hugs. Jenna looked great, wearing a short summer dress that showed off her curves and big bust.
Then his cousins hugged him as well, both quite the contrast to their mum. Both nineteen years old, they were skinny, with small tits and tight little asses.
After they all had assured Luke's mum several times that they would be alright for the weekend, they finally left her behind and walked towards the big clothing store in the mall. The weekend could begin!
"First, we need some new swimsuits," Jenna said, "I hope that's ok for you?"
"Of course," Luke replied.
"I can't wait to try the new bikinis!" Mia said.
"Yeah, you promised we could pick anything we liked, mum!" added Emma.
"Sure hun, I did promise that."
They entered the store and the three women went straight to the sportswear section to pick their favourite bikinis. Luke stayed close by, unsure what to do while they were browsing.
"What do you think of this one?" asked Emma, holding a tiny yellow bikini top to her chest. Only now did Luke realise that the shape of her tiny tits was visible through the fabric of her t-shirt, there was no bra underneath and her nipples were poking through. He couldn't help imagining what her slim body would look like naked.
"Hello, anybody home?"
"Err, yes, sorry! I was... err, yeah. Nice ti... I mean top. Nice top."
"Ok, thanks for the great review. I'll try it on anyway."
Before Luke could think too much about the awkward moment, Emma took him by the hand and pulled him along towards the changing rooms. He wanted to wait outside but his cousin pushed him into the small cabin where his aunt and Mia already hung their bikinis onto the hooks.
"It's way too small in here for the four of us," Luke protested, "I'll wait outside."
"No, hun. It's alright," Jenna insisted, "we don't want to lose you and we need your opinion. Sit here in the corner and we'll all fit."
Luke did as he was told and sat on the small stool. His aunt and cousins considered him close family and they had no clue what it did to poor Luke when they undressed before his eyes. Jenna dropped her dress to the floor and was in her underwear right in front of him. Then she opened her bra and gave it to him. Her heavy breasts were dangling right in front of his nose. Then she turned around and slid her panties down her legs, pushing her big round ass towards him. A familiar sensation formed in Luke's groin. Pressure built inside his pants as an embarrassing erection formed and his stiffening penis pushed against his shorts.
Then the twins stripped naked, exposing their skinny but equally sexy bodies and throwing their clothes into his lap. At least he could cover his bulging erection with them! Luke had never been this embarrassed before and he was too perplexed to talk.
Jenna was the first to be in a new bikini, a black model that supported her big bust, making her breasts look even more impressive.
"What do you think?" she asked Luke.
"I... I'm... they're..." he stammered.
"Are you ok, dear? You're all red in the face and sweaty!"
"It's... quite hot... in here."
"Oh sweetie, do you want to wait outside after all?"
"No no, it's ok!" Luke suddenly wanted to stay. He just had to get his shit together for a few more minutes! He didn't want to miss the rest of the show!
"I'll be alright, really. This looks great on you aunt Jenna!"
"Oh thank you hunny! I'll take it. Mia, Emma, show him yours."
Mia was wearing a small blue bikini that looked stunning on her small frame. Emma's yellow model meanwhile was so tiny, it barely covered anything. Luke's eyes almost popped from seeing his cousin's tiny tits and asses on display. He was rock hard by now and made sure the women's clothes covered his lap nicely.
"Which one do you like better, cuz?" asked Mia.
"They're both nice," he said.
"Oh, come on! You have to pick!" said Emma.
Luke had a clear favourite. The tiny yellow one was so revealing, he couldn't wait to see both his cousins in it. But he didn't want to admit that he liked the sexier option!
"Well, yellow is my favourite colour," he improvised.
