*****
Tommy's favourite heavy rock band were coming to town. He had waited all year for this. He begged his mom and dad to let him go see them but because of the adult content of the songs, there was an 18+ tag on the tickets - Tommy had just turned 18 but his parents still saw him as a juvenile, and weren't keen on letting him go at all, certainly not on his own. They had heard all kinds of bad things about the rough crowd that attended these heavy metal concerts.
He pleaded with his Dad to take him there, even willing to bear the embarrassment of being there with a parent, as long as he could see his favourite band live - but his father wasn't remotely interested and turned him down flat. Then he remembered that his older sister Kara had just turned 19. She was thought of as the more responsible one, a Grade A student who was just about to go off to college at the end of the summer vacation. He asked his parents if they would allow him to go if she accompanied him, and after much pleading, they agreed. He was over the moon. The only thing that stood in his way was convincing Kara to go. This would be difficult!

Kara was a beautiful, petite brunette with a slim, athletic body and pert C-cup breasts. She looked just like Shyla Jennings, the adult movie actress. Tommy knocked on her bedroom door quietly and poked his head in.
Kara was lying on her stomach with her earphones on, listening to music with her laptop in front of her. She was wear a plain white tank top and a pair of tight red short shorts, accentuating the curve of her perfectly pert, young tushy. She didn't notice him coming in and was playfully swinging her hips gently from side to side with the music. Tommy stopped and stared for a moment, mesmerised by his sister's cute, little teen ass, moving around delectably before him. His cock involuntarily started getting thick and heavy in his shorts. He imagined pulling those tights shorts down real slowly and burying his face in between those firm, young buttcheeks... he would take his time, kissing and licking every inch, pushing his tongue between her tasty pussy lips and licking her soft pink vagina from the inside... and of course, he wouldn't forget to visit her tight little asshole... he would make love to it patiently with his tongue, licking the tight, puckered rim with lots of slobber and pushing his pointed tongue deep inside it... and then he would...
Suddenly Kara felt the presence of someone in the room and turned her head.
"Oh, it's you! What do you want?" she said turning her attention back to her laptop. Kara didn't have much time for her snotty little brother. Apart from being siblings they didn't share any common interests.
Tommy was woken abruptly from his daydream but quickly regained his composure, casually putting his hand in front of his crotch.
"Er, hi. Kara? Could I ask a big favour of you?"
She was still deeply focused on her Facebook but she turned her head and raised an eyebrow, interested to know what this big favour might be?
"What is it?"
"Well, you know that my favourite band is doing a concert here in town this Friday?"
"No!" she shrugged. "Why would I care about that?"
"Well the thing is, Mom and Dad are saying that I'm not allowed to go on my own... even though I'm 18 now... so I was thinking... now that you've just turned 19 and everyone knows you're very responsible for your age..." (he knew this would help to coax her into agreeing.)
"Well, I was wondering if you would be able to go with me? Please?" He put on his cutest, innocent smile.
"Hmm", Kara looked back at her laptop for a moment, weighing up the offer. "And why would I want to go to see some smelly heavy metal band? What's in it for me?"
Tommy was already prepared for this. "I can do your washing-up duty for a month". He knew she hated doing her house chores and was sure that this offer would appeal to her. He also knew that she needed to get hold of a spreadsheet program for college. He had heard her asking their parents to buy her the latest version. She was really excited about going to college and was talking about nothing else.
"And I can get you the latest version of Office. A friend of mine can get a free copy and install it for you." Her ears pricked up when she heard this.
"Hmm..." she thought. It was quite an attractive offer. "Ok. I'll accompany you. But this is a one-time thing. And you better be real nice to me until this concert or I might change my mind."
"Oh, I will!" said Tommy enthusiastically, as he grabbed his sister, throwing his arms around her neck, and giving her a big kiss on the cheek. "Thanks so much Kara! I really appreciate this"
"Ok, ok. No need to get all sloppy." she said wiping her cheek.

The big day came. It was a warm summer's day. Tommy was wearing his best black jeans and his favourite T-shirt with the name of the band on it.
Kara came down from her room wearing a pair of denim shorts. They were an old pair of baggy jeans which she had cut off to shorts, thereby giving them a new lease of life. They were quite a loose fit, but still sat comfortably on her hips without needing a belt.
For her top she was wearing a white halter top with thin shoulder straps. It was kind of thin and Tommy could see her bra through it when she stood in the light. On her feet she was wearing a pair of strappy white sandals. Her shoulder-length brown hair bounced healthily as she came down the stairs.
"Ok, I'm ready. Let's go." she said to Tommy. "Hopefully it's not gonna be too boring for me."
"Oh it's gonna be great, Kara!" he replied. "I'm sure you'll have a good time too." (But little did he know how good...)
-
They got to the venue around 7pm, half an hour before the gig was due to start. As they were walking towards the entrance, Kara suddenly stopped and turned. She had seen something that drew her attention. She squinted, and then shouted "Jess? JESS?"
Tommy looked in the direction she was looking and saw a blonde girl about Kara's age. She had a nice tan and looked just like a young Jessica Simpson. She was with a guy about the same age, a year above him.
Jess turned to see who was calling her name. She saw Kara and opened her mouth in surprise. Then she smiled, waved back and started walking over to them.
"Hey! What are you doing here hunny?" She said to Kara when they arrived.
"Ugh." she sighed. "My brother... I promised to take him to this stupid concert. What about you?"
"Yeah, something along the same lines. My boyfriend wanted to go. He's a big fan. This is Jeremy." Jessie said introducing the guy with her. He was also wearing an official merchandise T-shirt. "What's your brother's name?"
"Tommy" said Kara, and Tommy nodded and smiled in response. "Tommy, this is Jess. She's in my class at school. She's going to the same college as me too." said Kara, smiling at Jess.
