The day, or should I say the night, of the concert had finally come. Actually, it wasn't a solo concert. Rain would sing along with Yuna, the other famous pop princess. According to the press, those two were hated rivals, so them cooperating came as a huge surprise in music industry.

I had had to avoid Suguha all day so that I wouldn't be tempted to do anything sexual with her; the last thing I wanted was to wear myself out a few hours before meeting two hot superstars, a meeting that there was a strong chance would turn sexual. What? I'm not vain, but, judging from what had happened in my life since the day I set foot on that all girls academy, the possibility of those two girls throwing themselves at me as well was not out of question in my mind.

And now, here I was, showing my pass card to the security guard. He checked it. 'You're a friend of Seven's?' he asked.

'Err, yeah, a friend,' I answered awkwardly, recalling all inappropriate things I had done to the 12 year old that I bet that sturdy man would crush my skull if he knew about.

'Okay, you can pass,' he gave me the card back.

I wandered in the dressing rooms corridors for a while, until I found the room where Rain and Yuna were preparing themselves. Wait, they were sharing a room? I had expected two singers of their caliber to at least enjoy the luxury of having seperate rooms.

I knocked the door. 'Who is it?' I heard a voice. Rain's voice! A person known by billions of people worldwide had just addressed me!

'Umm, I have a message from your sister,' I said awkwardly.

I heard the door being unlocked. Rain opened the door. She was a really sweet girl, with long, crimson hair and brown eyes. She was dressed in a maid costume. I guess that had something to do with the performances concept that night. She offered me the kindest smile I had ever seen. 'Oh, you're a friend of Seven's? That's so nice.'

Yuna showed up next to her colleague, dressed in the same maid costume. Yuna had long, grey hair, with a bun on each side of her head, and red eyes. 'Whoah, hold your horses, Rain,' she said, not seeming as kind as her redhead colleague. 'Can this guy prove he knows Seven?'

'Well, he has her pass and is wearing her school's uniform...'

'So what?' Yuna interrupted Rain. 'Any psycho can order custom clothes online that look like a school uniform, kill your sister, steal her pass and...'

'YUNA! That's enough,' Rain snapped. She turned back to me and, regaining her sweet expression, said: 'Forgive her. She can be a real bitch sometimes.'

'Umm, it's okay,' I laughed awkwardly, stroking the back of my head.

'Come in,' the redhead kindly invited me.

I entered the room and looked around. There was a large bed, a mirror on a desk and posters and magazine covers depicting either Rain or Yuna all over the walls. 'Wow,' I commented.

'Heh. Are we great or what?' Yuna boasted, eliciting a glare from Rain.

'I'm surprised, though, that you two decided to perform together,' I commented, trying to maintain conversation. 'I mean, I have read so much about your rivalry and...'

'Don't believe into the presses bullshit,' Rain sweetly scolded me. 'Actually, we are pretty good friends, despite how much of an asshole Yuna can become at times.'

The grey haired girl retorted by sticking out her tongue. Lol, those two must have a Leafa/Sinon like frenemical relationship.

'Anyway, we decided to go on this tour together to show the whole world that music brings people close,' Yuna continued in the redhead's place.

'Wow, cool,' I exclaimed.

'So,' Rain casually had a seat on the bed. 'You said you had a message from my sister?'

'Oh, yeah, about that...' I fumbled in my pockets, took out the folded piece of paper Seven had given me and gave it to Rain.

She read it. Judging from her expression not changing much, I'd say that piece of paper did not say anything important. Rain beckoned to Yuna to sit next to her and showed her what the paper said. The two girls shared a giggle. Okay, now I was really curious, but it was not my place to ask.

The door knocked. 'Miss Yuna, your part begins soon,' an assistant's voice was heard.

'Anyway, I have to go,' Yuna said, standing up. 'You guys stay here and get to know each other until I have finished my first two songs.' Wait, was her expression... meaningful?

Yuna left the room and Rain locked the door. Then she sat back on the bed and beckoned to me to do the same. I did so. Awkward silence. I tried to think of something to say. 'Umm, so, miss Rain...'

'Just Rain!' she corrected me with a smile.

'So, Just Rain... I mean Rain, have you always wanted to become a singer or...'

The girl interrupted me again by handing over the piece of paper I had given her earlier. I looked at her, confused. 'Go ahead, read it,' she encouraged me.

Hesitantly, I lowered my eyes and started reading: 'Dear fellow sister, recently, I was devirginated. I know you probably consider me too young to be involved in such activities, but, please, do not become angry. The boy that brought you this message has one of the biggest male, reproductive organs I have seen in my life; and I have seen many, in educational, scientific books I have read as well as in educational, scientific videos I have watched. I advise you to utilize his copulatory organ yourself too. Sincerely, your beloved sibling, Seven.'

I froze in terror. That stupid, little genius had gone and ruined my life! I could already feel the lifers' dicks tearing my ass apart in jail. I turned to Rain, expecting to find her outraged: 'Li-listen, I can explain, I...'

Rain hushed me with her finger on my mouth. She was smiling. Huh? She was not mad?

'Actually, I really want to see whether that dick of yours is really that big,' she said.

I got a serious expression, though, inside, I felt delighted, both for nobody pressing charges against me after all and for this night turning sexual.

I stood up and lowered my pants. 'Holy shit!' Rain exclaimed, her eyes widened. 'Baby sis wasn't exaggerating after all!'

'Thank you,' I chuckled, trying to sound modest.

Rain walked to the desk. She pushed all the makeup stuff off it, producing a loud sound. With her back turned to me, she placed her hands under her skirt, removed her underpants and tossed it away. She turned to face me, got on the desk, resting her torso against the mirror, opened her legs and motioned for me to come close.

I ran to her, almost tripping over my lowered pants, which made her giggle. I took a condom out of my pocket, put it on and slowly entered her womanhood. She placed her arms on my shoulder and wrapped her legs around me while I held her by the waist for better balance. Not having time to fully undress, since Yuna would be back soon, which meant it would be Rain's turn to get on stage, we started thrusting the way we were. Occasionally, I would grope her exposed legs or lean and kiss her lips or the part of her shoulders and back that her maid dress left exposed.

I was about to cum when the door knocked. 'Guys, it's me,' Yuna's voice was heard. Fuck. I wanted so bad to stay in the redhead, but I had to pull out so that she could go. Rain ran to open the door and Yuna stormed in the room. 'Hurry, girl,' she said.

Rain was about to leave. 'Wait, your underpants,' I reminded her.

Rain looked at her tossed underpants. She pondered it for a moment and said: 'I think I won't need these to perform. In the future, every time you watch this concert on youtube, you will be the only one to know that I performed with no underpants and my freshly screwed vagina exposed while the crowd was cheering.'

That statement made my dick, which had started going down by then, regrow to full size! Rain winked and left, Yuna locking the door.

That moment, it struck me; Yuna had read Seven's message before and, right now, she was looking at me with my underpants lowered. She knew evverything!

Before this could sink in any further, the grey haired girl tossed her own underpants and assumed the same position on the desk, taking Rain's place. 'Hurry, boy,' she said imperatively, tapping her fingers against the desk. 'Rain will be back soon. No time for small chat or foreplay.'

After my initial shock, I shoved my dick in her vagina, still wearing the same condom I had used with Rain earlier. We started thrusting and moaning, in the same fashion as I had done with Rain before.

Once more, when I was about to cum, Rain was back and I had to half heartedly remove my dick from Yuna's gorgeous vagina. Then I put it back in Rain's.

To make a long story short, that was how all night went. I was fucking Rain as long as Yuna was on stage singing and vice versa. Every time I was close to climaxing, I had to pull out and change parnter. All the while, I was wearing the very same rubber! It was a pleasure and torture at the same time. A mixture of heaven and hell.

When the concert was finally over (the final song being a duet, which meant I had to stay alone in the dressing room for a while), we could finally be all three of us together, strip to nudity and take this to the bed. I was now fucking both of them at same time, constantly pulling out of one girl and penetrating the other. Sometimes I was thrusting against Yuna while groping Rain's boobs, sometimes I was thrusting against Rain while groping Yuna's leg etc Not once did I change condom!

I desperately needed to orgasm! I had been restricting that urge all night. That would be a hell of a load. My two partners had cummed at least twice each until then. When I decided to cut loose, I happened to be inside Rain at that time. I screamed. It was an ultra intense and long lasting climax. I enjoyed half of it in Rain and, in the middle of climaxing, with lightning speed, I pulled out and shoved my dick in Yuna, enjoying the second half of my orgasm in there.

We all collapsed, panting. Thankfully, mom's curfew wasn't strict, so I could stay there as long as I wanted, even sleep with the girls. And so, we fell asleep next to one another, exhausted.

Remind me to thank Seven for that!
