‘Shit. I’ve never seen Octavia act that way. What a witch. She had no right to make us leave. The cheek of it. I’m his sister for God’s sake,’ Britney grumbles furiously as we make our way to our seats. ‘Bloody hell, she wouldn’t even have a job if not for my brother.’

‘Look,’ I say, ‘I wanted to slap her too, but Cash has taken so much trouble to organize everything for us that the last thing I wanted to do was cause a scene just before he went on stage.’

‘But Cash wanted us to stay,’ she insists.

‘I know he did, but does it really matter in the bigger scheme of things? You’ve had an amazing time so far and it can only get better. Remember the twin with dung?’

She grins. ‘You’re right. We’ll have a wonderful time.’

Cash was spot on, we have one of the best vantage points in this arena reserved entirely for us, and Sean has arranged for drinks and snacks to be brought to us as well. The excitement is mounting in the stadium and everyone is full of expectancy and energy as the time moves closer to the band’s appearance. Eventually the entire audience of more than 15,000 people is chanting for the band.

The chanting stops and the crowd erupts into a loud roar of excitement as five figures, more shadow than real, saunter out on to the darkened stage. Flashbombs explode around them as the driving beat of the band starts and stage lights bathe the band in a breathtaking kaleidoscope of fast moving color. Huge screens surrounding the arena catch every move they make.

‘Bonasera Milano,’ Cash shouts, his hand lifted high above his head.

The fans scream the greeting back to him, and the air literally vibrates.

‘Are you ready to get down and dirty?’ he asks.

The applause and shouts of si is instant and deafening.

Gavin says something to the audience too, but I don’t hear it because Cash is looking directly at me. My heart stops beating. I can’t move. I just stand there transfixed and staring until he winks and turns away from me. I watch him energetically run to the other end of the stage as the intro to the first number, Let’s Hang Out, starts playing. The crowd goes crazy. Cash’s deep rich voice sparks more wild screaming.

Britney, like most of the fans, has jumped to her feet clapping, cheering, and dancing to the beat. The atmosphere is so electric with the throbbing of the powerful beat and the grinding of all the people below that it is infectious and I find my body reacting to the vibe too.

I remember that first time in Atlanta being there right in the heart of the energy and how good I felt, seeing Cash up on that stage, so close but so unobtainable. Now here I am with a VIP seat right at the front of the stage and he’s just as gorgeous as ever, but this time around he’s mine.

At least for tonight.

I look around at the sea of young girls swaying to the beat and filled with wild excitement at the sight of these handsome, virile young men and for the first time I understand what it must be like for these performers. Out on that stage they are larger than life. Heroes. Buzzed up with alcohol and out of control hormones, they look out across the arena at the adoring fans and see prey.

Although the band members are all handsome and have good voices, Cash has that something extra. He exudes confidence, presence and raw sex appeal. He’s also the most gorgeous. Hearing Cash’s name being screamed by so many beautiful girls makes me slightly insecure and I have to remind myself it’s me he has chosen to be with him tonight.

For one hour the band struts and performs dance moves with seemingly unlimited energy, lapping up all the love coming from their fans, as hit song after song reverberates across the packed arena. Britney is still boogieing next to me, trying to encourage me to join in using various facial expressions, but the heat all around is so intense I have to sit to cool down a little.

Then it is time for the finale and Tinie Tempah dressed all in black with a red jacket joins the band on stage. To Britney’s delight Tinie wishes her a happy birthday. I look at her with a grin and she is red with exertion, pleasure and excitement.

A girl brings some boxes to the stage. The band members take the boxes and sit with their backs turned away from the audience. When they turn around they are all wearing red shoes that match Tinie’s red jacket. Together they sing Written in the Stars and I feel the song in my bones. Like the lyrics of the song seasons come and go, but I will never change. My love for Cash is written in the stars.

Afterwards they all do Dizzee Rascal’s famous jump routine and the crowd becomes an enormous heaving mass of people jumping up and down while they scream, ‘Jump, jump, jump.’

Panting, the band announces how much they love their audience and thanks them all. ‘Grazie a tutti. See you all next year,’ the guys say before the notes for their biggest hit ring out. The Girl Who Can’t Say No. For the chorus the band lets the audience sing the words.

Two encores later, the crowd is clapping persistently, begging for more, but the guys say their final farewell. ‘Buona notte Milan.’ They bow in formation and run off the stage.

Even as they disappear from view Sean is already there to fetch us back to the dressing room. The cool air along the dressing room corridor hits my face and I welcome it after the steamy atmosphere in the arena. Britney is still buzzing and smiling happily when a boy with red hair and freckles comes up to us.

‘Britney?’ he says with an English accent.

‘Yeah,’ she says cautiously.

‘Your brother has arranged for you to meet Tinie Tempah.’

‘What?’ Britney exclaims.

‘Yup, I’m supposed to take you to him. The man has a birthday gift for you.’

‘A birthday present, for me?’ Britney repeats in astonishment.

‘If you want to come with me I’ll take you to him and bring you back.’

She turns to me. ‘Come with me?’

I shake my head and smile at her excitement. ‘You go ahead. I’ll wait for you in Cash’s dressing room.’

Smothering the squeal that threatens to escape the back of her throat, Britney clasps her hands to her face before planting a big kiss on my cheek.

‘This is the best birthday ever,’ she tells me and goes off with the man.

I am still smiling as we walk down the corridor when I spot Cash walking towards us.

‘I’ll be off then,’ Sean says. Lifting his hand in a wave, he starts walking back to where we came from.

I stand where I am, frozen, and watch Cash stride towards me. He seems so different. When he reaches me I look into his eyes and I can see that he is wired up. The performance has left him with an adrenaline high.

I feel my body responding to his. I can almost hear his heart thudding hard in his chest. There is a sheen of sweat on his face and body. His T-shirt is drenched and clinging tightly to his torso and every muscle is prominently on display. His skin is tingling as if he is full of static electricity.

His eyes drop from my face to my chest. Then he takes my wrist and pulls me along the corridor until we get to a door. He kicks it open and yanks me into a small toilet. He locks the door and turns to me, breathing hard.

He grabs me by the waist and pulls me hard towards him so I slam up against his body. Then he swoops down on my mouth and fucking devours me. Eats me alive. It’s like the Fourth of July fireworks. My hands come to entwine in his dripping wet hair. I suck his tongue when he sticks it in my mouth.

‘Fuck me, Tori,’ he growls.

‘What, here?’

He shakes his head slightly.

‘I thought fucking in the toilet lost its charm after a while,’ I say.

‘When you come to me looking like this, I’ll fuck you anywhere,’ he says roughly. He pulls my skirt up so it bunches around my waist, rips my panties right off my body, and chucks them to the ground.

‘Oh,’ I gasp, aroused by the violence and urgency in his action.

He swivels me around so I am facing the cistern and my feet are planted on either side of the toilet.

‘Hands on the wall,’ he orders.

I obey immediately and hear the sound of the metal teeth of his zip, and the rustle of his clothes being hurriedly yanked down. Seconds later he pulls my ass upwards and plunges his cock all the way into me, the entire length in one single movement.

‘Oh God, Cash,’ I grunt.

Holding my hips tight he powers into me energetically. Thrusting deeper and more powerfully until it feels as if the whole bathroom stall is vibrating and shaking with his thrusts.

‘This feel good to you?’ he snarls, slamming even harder into me.

‘Yes,’ I gasp.

‘Yeah?’

‘Yeah,’ I pant.

‘You’re going to let me fuck you in the toilet again?’

‘Yes,’ I cry.

‘After every concert?’

‘Yes. Every. Concert.’

‘Good.’

‘No more groupies?’ I ask.

He doesn’t pause or still. ‘No more groupies.’

‘Only me?’

‘Only you.’

And then I find myself climaxing. It’s so powerful it stuns me. My body vibrates uncontrollably. Through the waves of ecstasy, I feel Cash’s cock grow inside me. I feel him explode and maybe I even feel his hot seed flood into me. Panting hard and with him still buried inside me, he places his hands over mine on the wall. I turn my head and he kisses me.

‘You’re a bad boy,’ I whisper.

‘You’re a dirty girl,’ he whispers back.

I smile.
