Carparking.

The walk back to the car felt much different from the walk to the arena. Neither of us said much at first. We were both still caught up in the noise and excitement of the concert, but there was another reason for the silence too. Every so often Trish would glance at me, smile, and then quickly look away again.

When we finally reached the makeshift car park, I stopped dead. “Oh, you've got to be kidding me.”

The place was absolutely jammed. Thousands of people were pouring out of the arena, all heading toward the same rows of cars. Headlights stretched into the distance, and somewhere ahead of us a chorus of impatient horns had started.

Trish laughed. “This is going to take forever.”

I looked along the line of cars. “We're not getting out of here anytime soon.”

“So, what do we do?”

“Wait, I guess.”

We reached the car and climbed inside. I started the engine briefly to get some heat going before switching it off again.

Trish looked through the windshield at the unmoving line ahead. “Yeah. We're definitely waiting.”

I leaned back in the driver's seat. “At least we've got somewhere to sit.”

Trish smiled. Then she looked down at the plastic merchandise bag sitting between us. “Actually…” She pulled out the new Weeknd shirt I'd bought her. “I want to try this on.”

“Now?”

“Why not?”

She opened the rear door and climbed into the back seat, still holding the shirt.

I turned around. “What are you doing?”

“Changing.” She grinned. “And don't look.”

I raised both hands innocently. “Wouldn't dream of it.”

Trish disappeared behind the front seat, and I deliberately stared through the windshield. For about five seconds. Then curiosity got the better of me. I glanced into the rear-view mirror.

I immediately caught a glimpse of Trish halfway through changing, the old Fleetwood Mac shirt discarded beside her and her new shirt being pulled over her head. For an instant, I caught her sitting there in a white bra before the new shirt dropped into place.

She caught me looking in the mirror. Instead of getting angry, she simply stopped and raised an eyebrow. “I said not to peek.”

“Sorry.”

She smiled knowingly. “Did you like what you saw?”

I couldn't help grinning. “Yes.”

Trish finished pulling the new shirt down and looked at herself in the darkened window.

“It fits.”

“It looks good.”

She turned back toward me. There was a pause. Then she smiled again. “Come back here.”

I looked at her.

“What?”

“You heard me.” She shifted across the back seat, making room beside her. “Come on.”

I glanced once toward the endless line of traffic outside before turning off the interior light. “Are you sure?”

Trish nodded. “I'm sure.”

I opened my door and climbed into the back beside her.

For the first time since we'd left the arena, it felt like we were completely alone. No music, no screaming crowd, no thousands of people surrounding us. Just the two of us sitting in the back seat of Heather's car, waiting for the traffic to move.

Trish looked down at her new shirt, then back at me. “Best free concert ticket ever?”

I smiled. “Definitely.”

Trish reached out towards me and took my hand in hers. I moved close towards her and was about to lean in and kiss her again.

Trish reached out towards me and took my hand in hers. I moved closer towards her and was about to lean in and kiss her again.

What she said stopped me in my tracks.

“Heather says you have a crush on your next-door neighbour Rebecca.”

I stared at her.

“What?”

“Rebecca.” Trish watched my face carefully. “Heather told me you've been in love with her forever.”

“I wouldn't say forever.”

“But you do like her?”

I hesitated.

There didn't seem to be any point in lying. Not after everything that had happened tonight.

“Yeah,” I admitted. “I do.”

Trish's expression changed almost imperceptibly. The smile disappeared from her lips, and for a moment she looked down at our hands.

“I knew it.”

“You knew?”

“Heather's mentioned it before.”

I frowned. “What exactly has she been saying?”

“That you're completely gone on Rebecca. That you've been best friends since you were kids and that you've always wanted it to become something more.”

I leaned back against the seat.

“That sounds about right.”

Trish was quiet for a moment.

“So tonight…”

“What about tonight?”

She looked up at me.

“Was it just because Rebecca wasn't there?”

The question caught me off guard.

“No.”

“Then what was it?”

I looked at her for several seconds before answering.

“You.”

She blinked.

“What?”

“You asked me to come tonight. You wanted to be here with me. We had a great time together. Everything that happened tonight happened because we were together.”

Her expression softened, but she still looked uncertain.

“Even though you like Rebecca?”

I nodded slowly.

“I've liked Rebecca for years. That's true. But tonight I wasn't thinking about her.”

Trish squeezed my hand.

“You were thinking about me?”

“Yeah.”

A small smile returned to her face.

“That's what I wanted to hear.”

She shifted closer until our shoulders touched.

“I've spent years thinking of you as Heather's annoying little brother,” she said quietly. “Then somewhere along the way that stopped being how I saw you.”

I didn’t get a chance to react before Trish lifted up and over onto my lap. Her tongue was in my mouth, and she was kissing me harder than even before. It was hot, passionate and exceedingly intense. Again, she lifted my hands, bringing them up and under her new The Weeknd T-shirt. I could feel her incredible firm and perky tits through her lace bra before I pulled the cups aside and clutched at her exposed flesh. Trish in turn was grinding her hips ardently on my rapidly returning hard-on. I was almost instantly back to full mast before she reached back behind herself to unhook her bra and give me full access to her body.

It felt like forever but must have only been a couple of minutes before Trish instigated things further. She pulled back as I continued pinching her nipples. She fumbled with the button on my pants before undoing them and pulling them down to my knees.

Oh shit! Was this really happening? I was going to have sex for the very first time with Trish. My sister’s best friend.

With my cock exposed and standing straight up, Trish got off me to quickly slip one leg out of her jeans. She climbed back on me and pulled the front of matching white panties to the side as we drew close together.

“I’m not on the pill, so just pull out, ok?” Trish asked, and I nodded.

She moaned as my head entered her, parting her lips, and she started sliding down onto my cock. It was so hot and wet I’d never felt anything like it. I grabbed onto her hips as Trish took complete control of the situation. She rocked her hips against me, driving her pussy back and forth along the length of my shaft. She was moaning freely as she worked herself in pleasure. I reach around to grab her arse and help her down onto me as we ground our privates together in a quickly dripping mess.

The car must have been rocking to the outside world as in less than five minutes we were interrupted by a group of people shouting and banging on the windows of our car. I expected Trish to immediately stop, but instead she told me, “Just keep going!”

Her rashness must have been due to her closeness, as just seconds later I felt her pussy drench me in new wetness and start to close even tighter around me. Trish cried as she came on top of my cock, throwing her head back and slamming down as hard as she could. The throbbing walls of her cunny felt incredible as she continued to orgasm past the sixty-second mark.

A little too good it felt as I felt a tightening in my own balls. “Trish! I’m getting close,” I warned

She heeded my caution and slid off my cock at almost the last second. Still straddling my legs, Trish held the front of her new top over my cock and started to stroke me. It shielded what was happening inside from anyone looking through the windows. Trish’s hands made short work of my wet and greasy cock. I started to cum, shooting off powerful thick blasts of my jizz that splashed all over the front of Trish. I couldn’t see, but I coated her tits, stomach and the inside of her shirt with my heavy load.

Our finale was greeted by a round of shouting applause from outside as Trish dropped onto the seat beside me.

“Oh, my God! Get me out of here,” Trish cried as the reality of the situation returned to us.

I had to pull my jeans back up before I was able to climb between the two front seats and start the car. Luckily, the crowd was thin enough that I could drive away immediately. Trish stayed in the backseat, but I could see her laughing through the rearview mirror. One leg in her jeans and one leg out still. Her sweet little teenage pussy turned red and shiny in the aftermath.
