A son and daughter

You turn around and see a guy and a girl. The guy looks Like he is in his early twenties and is an almost perfect copy of what you imagine his father looked at that age. He is wearing a uniform for some retail store. The girl is tiny. She is so short she would probably only just reach your shoulder height. She has long straight black hair that reaches to her nearly non existent ass she is wearing the tightest short shorts you have ever seen and a tank top with no bra. You can clearly see her nipples through the fabric, but then with breasts that small she probably doesn't need them. Brother and sister have a slight Asian look to their features, but you aren't sure.

The son is introduced as David he shakes your hand looking awkward, barely able to look you in the eye. And to think I'm the awkward shy one you think to yourself. The daughter is Kim as you are introduced you she some strong emotion flash in her face before she is all smiles and embraces you like a long lost sister.

"Ok Amy, Richard and I are going to be going away for a few days to catch up. Do you think you will be Ok with David and Kim for a few days?" your mother asks.

You aren't sure, after all you've only just met these people. Then again they are family now and you are supposed to trust family. "Ok mum, you guys have fun."

With that Richard pulls your mum away and you a left with these complete strangers. "Ok" David says "we need to be going or I will be late for my shift. kim looks around and asks" where are you bags?"

You pick up your carry on and gesture to it "right here. Mum said it was cheaper to just get rid of everything and buy new stuff when we get here. With the exchange rate it turns out pretty cheap. I just have the stuff I couldn't bare to part with."

Kim looks at the small bag and asks" how much clothing do you have?"
You tell her you have enough for a couple of days. "Are they all like what you are wearing?" she asks.

"What's wrong with what I'm wearing?" you look in worry at your jeans and long sleeve t-shirt.

"Oh there's nothing wrong with it, it's just a little warm." She replies with a laugh.

As you walk out the exit door to the terminal you a hit by a wall of hot dry air. You instantly start sweating. " I see what you mean. It's snowing back home, I guess I didn't think it would be the middle of summer here."

kim shrugs "It's the start of a heat wave. There will be highs over 43 every day for another week."

You quickly do the conversion in your head. "That's one 109 Fahrenheit" oops, now they know you're a massive nerd. "Wow, I would have to look that up" David replies "you must be really smart."

You make an awkward excuse about having seen it in a movie and hope they bought it. The last thing you need is to have no friends yet again.

"Whatever as I was saying I think we need to go shopping asap. You will make yourself sick wearing all those layers in this weather."
Kim asks David to drop you off at the shops instead of at home then calls a friend to come meet you two.

David pulls up in the car park and heads in to work his shift. You leave your bag in the boot and follow Kim into the air conditioned interior. As you sigh in relief Kim turns to you and says...
