"It's not fair!" Megan screamed at her parents.
"I'm sorry but you're not staying here alone, either come with us or go with Jack."
"Fine, I'll go with jack." She said storming off to her room.
Megan had wanted to stay at home while her parents went off on their cruise and her twin brother Jack went camping with his friends. Megan and her twin brother Jack were 18 years old, and had both finished school for the summer.
Megan was 5'6, and had a slim and athletic body, as would be expected of the head cheerleader. She had dark brown hair that was long and straight which she wore in a ponytail with her fringe swept behind her ear.
Jack was slightly taller than his sister at 5'8, he was incredibly buff and spent a lot of his time at the gym. His hair and eyes were brown just like Megan's, worn in a short haircut.
"Looks like I'm coming with you." She said walking into Jack's room.
He looked up from where he was packing his rucksack with all he would need.
"Ok, go and pack your things, were leaving in an hour so we get there before dark."
Megan went to her room and packed a bag with some shorts and a few vest tops and various other things.
She came out of the house to the driveway where Jack was already sat in the car. She threw her bag in the back of the car and climbed into the passenger seat. The drive took a good few hours. They had just turned off the main road into the forest when Jack's phone buzzed with a text.
"Hey man, we broke down on the way out, we're gonna have to wait until tomorrow and meet you there when the car is fixed."
"Looks like it's just us two tonight." Jack said after reading the text.
"Oh well, I'm sure I can put up with you for a few hours." Said Megan evidently still sulking about not being allowed to stay at home alone.
After half an hour of driving down the narrow gravel track through the woods they arrived at a small car park. They got the tent and their bags out of the car and locked it up. They walked through the woods, there was no path they were following. After the walk they arrived at their final destination which was a clearing in the woods.
They set up the tent and unpacked their bags and were just making themselves something to eat when Jack's phone buzzed again.
"They don't have the parts we need, looks like we won't be coming."
"Was that your friends again?" Megan asked.
"Yeah, they can't come, the garage doesn't have the parts."
"So it's just gonna be us two for a week?"
"Yeah, looks like it." Jack said sensing Megan's bad mood. "But don't worry there's loads to do."
They sat in silence and finished their food and were clearing away when Megan spoke up.
"So what is there to do?"
"Let's go swimming."
Jack led Megan to the lake and without hesitation stripped to his boxers and jumped into the lake. Megan was hesitant at first but then because of the sweltering heat pulled her vest off. She had on a plain black bra that held her breasts perfectly in place.
"No peeking." She said as she pulled her shorts down.
Jack couldn't help but stare as he watched her shorts slide down her long legs, underneath she had on a tiny black thong that did little to cover her. She joined Jack in the lake.
"What's with the sexy underwear" he asked her.
"To be honest I was hoping to catch the attention of one of your friends but looks like that's not gonna happen. Anyway I said no peeking!" She playfully splashed him.
He splashed her back as she grabbed hold of him from behind in an effort to keep his arms still.
"If I had known it was just us I would have packed more underwear than just thongs." she said in a slightly embarrassed voice.
"You only brought thongs?" He asked laughing.
"Shut up! Yeah that's it." She said swimming to the shore.
Jack followed her and they both lay on the beach in their underwear letting the sun dry them off. There was a long silence and Jack kept looking over at Megan.
"I think that thong kinda suits you." He said breaking the silence.
"Erm, what?"
"It looks kinda good."
"I'm your sister you weirdo." She said playfully chucking a twig at him.
"I know, I know, I'm just saying you're not exactly ugly."
"That's probably the nicest thing you've ever said to me, you're not too bad yourself." She said smiling.
Megan got up and walked back to the tent carrying her clothes. Jack's gaze followed her pert ass all the way, he couldn't believe he was looking at his sister like that but something about her made it impossible not to.
