It was lunch time at the academy. I was sitting at a table outdoors and eating, along with the whole original group: Asuna, Leafa, Lisbeth and Sinon.

Suddenly, Seven showed up, carrying her disk, and joined us.

'Hello, fellows,' she greeted us as she was sitting. 'Which of you would like to come over to my chamber, when today's courses are over, to see my new invention?'

Knowing what Seven's experiments usually lead to, all of us took frightened expressions, except Leafa, who never learns!

'Umm, I'm sorry but I can't, Sev,' Sinon said awkwardly and stood up. 'I have to go and do... something!'

'Yeah, yeah, I've got to go and do something too,' Lisbeth stood up and started following Sinon.

'Like what?' Seven asked innocently. (For all her genius, she doesn't get innuendos easily most of the time.)

'Umm... to feed my tarantula,' Lis answered hastily.

'You don't have a tarantula,' Seven pointed out.

'Then I'll buy one,' Lisbeth called out, running away behind Sinon.

'Well, I have to do something too,' Asuna sweatdropped. 'You know... something about... something!'

She was about to stand up, but, with a mischievous smile, Leafa used a martial arts hold to keep her red headed frenemy pinned at the table.

'KIRITO, HELP!' Asuna shrieked, flailing her arms towards me. She was not afraid of Leafa hurting her; she was afraid of Seven's invention!

I sighed.

'Okay, I'm not stupid!' Seven snapped and stood up abruptly. 'Why does no one want to see what I have developed?'

'Because, Seven,' I sighed again, 'usually, your inventions have disastrous effects, such as getting all my girlfriends pregnant (Chapter 25), drugging us into having an overnight orgy in the classroom (Chapter 55) and creating a huge monster with a really perverted brain (Chapter 87).'

'Oh,' Seven looked at the ground, with childlike disappointment in her charming eyes.

She turned around and started walking away. 'Then I guess none of you wants to see my Potara Earrings!' (I bet that, at that moment she was turned around and spoke those words, a meaningful smile formed on her lips.)

'WAIT WHAT?' Asuna, Leafa and I cried in unison.

Seven turned to us and winked, smiling. 'All three of you, in my room, after the courses!'

That afternoon, Leafa, Asuna and I were in Seven's room, the last explaining to us what her invention was about.

I was sitting on a chair, Asuna sitting on my lap and me casually caressing her hair. She was wearing her school uniform.

Leafa was lying on the bed, on her belly, supporting her torso with her elbows and swinging her raised calves. She was wearing a white t shirt, red shorts and flip flops.

Seven was showing us the Potara Earrings and explaining to us: 'Those two pieces of jewellery contain tiny bio magnets that are activated as soon as two people put them on and stand side by side, causing one's cells to combine with the other's.'

'In other words, with these thingies, two people merge into a new being,' Asuna casually deduced as I was playing with a lock of her hair.

'Just like the Potara Earrings in Dragon Ball Z,' Leafa cried before I could speak those words myself, jumped to her feet and clapped excitedly.

'Yes, that's why I named them Potara Earrings,' Seven rolled her eyes.

'To honor the greatest anime series that has ever graced mankind with its presence,' I deduced.

'Do you all fellows have a thing for stating the obvious?' Seven sighed, annoyed.

Leafa stuck out her tongue and snatched the earrings, eliciting a gasp from the younger girl.

'I wonder what kind of being would be produced if I merged with Kirito,' I heard her mumble as she was examining the earrings in her hand.

I gulped, freaked out by the thought of the transvestite like abomination that would be created that way.

'I'm afraid it doesn't work that way, mentally incapable, blonde girl,' Seven closed her eyes and took hold of her nose, in an attempt to calm down herself. 'For the potaras to work, the two users must be the same gender and about the same height.'

I sighed in relief.

'So I guess I can't merge with you either, pretentious kiddo,' Leafa said to Seven, caressing her chin, pensive.

Then her eyes gleamed! She turned to Asuna. 'Are you thinking what I'm thinking, red?'

'Bring it on,' Asuna got off me and clapped.

She took one earring. The two girls stood side by side and put them on.

A blinding light flooded the room. When visibility was restored, before my and Seven's surprised eyes, a new person was standing in place of Leafa and Asuna.

She was visibly taller than either of them and, of course, than me! She had long, strawberry blonde hair (I guess a mixture of Leafa's blonde and Asuna's red) tied in a ponytail. Her eyes were green, but had a darker green hue than Leafa's (I guess that was due to Asuna's brown eyes). She was wearing a skirt that looked like Asuna's school skirt, except it was red like Leafa's shorts. On her torso, she was wearing a t shirt that looked like Leafa's, except it was the same color as Asuna's school uniform. Her outfit was supplemented by knee high, white boots. (Okay, I have no idea where the boots came from!)

I turned to Seven. 'Umm, scientifically, how is the fact that their clothes merged as well, explained?' I asked.

'I have no idea!' the usually arrogant little girl admitted, eyes widened.

The new entity looked around. Finally, she looked at Seven and me, raised her arm and greeted us. 'Hello,' she said, her voice sounding like Asuna and Leafa were speaking at the same time. (In a sense, that was exactly the case.)

I turned to Seven again. 'Umm, what should we call her?' I asked.

'Aseafa? Lasuna? Both sound awkward,' Seven caressed her chin, troubled, examining the taller (way taller!) girl, as if examining her would help her come up with a name.

'We could call her Luna. But that would create confusion to the readers, since Luna is also the name of a girl I fucked in Chapter 71,' I said. (Yes, ladies and gentlemen, after 87 chapters, this is the first 4th wall breaking moment in this fic!)

'Shut up!' the fused girl's thundering double voice resonated, making both Seven and me gulp. 'I will decide what my name is. Since I was produced by the power of unity, you will call me Uni!'

'Umm, okay,' I gulped again, unsure what to expect.

Uni walked over to Seven, her towering figure casting its shadow on the little girl. She crossed her arms. 'How long will the fusion last?' she asked.

'Umm, half an hour, ma'am,' Seven gulped.

'Good,' Uni smiled. 'So I have some time to enjoy myself.'

To enjoy herself? Did she mean what I thought she meant? Not that I didn't want her to mean that, mind you!

The fusion girl pointed at me imperatively. 'Undress,' she commanded me.

'Y-yes, ma'am,' I stuttered.

I sat on the bed and started removing my clothes while watching the standing Uni doing the same.

I was now nude. Uni was nude too, except she had left her boots on. (Fetish?)

Seven decided to sit on a chair and watch us, taking notes. 'Don't mind me, fellows,' she said, more bravely than earlier. 'For me, all this is an experiment. Entertain yourselves while I'm doing my job.'

Her words could barely reach our ears. That's how turned on both Uni and I were at that moment.

The fusion girl got on her knees in front of me and started giving me blowjob. I raised my eyes to the ceiling and sighed.

Her technique was... unlike anything I had experienced until then. The way her head was bobbing, her hands were holding and squeezing my shaft with her mouth moving onto it... her movements were smooth and deliberate like Leafa's and at the same time raw and straightforward like Asuna's!

'And now, how about a boobjob?' she asked at some point.

'YES, PLEASE,' I cried, gripping the mattress in anticipation.

Uni giggled and trapped my dick between her boobs, which were (I only now noticed!) huge! I dared to say, a little larger than Leafa's! Although I'm anatomically gifted and I know it, my cock looked so tiny at that moment, as it was being engulfed between those two beauties.

We continued like that for a long time. Past a point, I couldn't help leaning forward and planting kisses on Uni's lovely neck. Although I could tell, from her moans, that she liked that, it also made her angry.

She stood up abruptly and took two steps back, arms crossed. 'Who gave you the right to take initiatives?' she glared at me.

'Umm, sorry,' I stood up. 'I...'

'Lie down, slave,' she yelled and, with a push kick, forced my back to the bed, leaving a boot print on my belly!

Gosh, that hurt! A lot! I almost vomited in pain! I could tell that Uni meant to do it lightly, but it seemed that, just like in Dragon Ball, when two people fuse, the person that is born is stronger than the two of them together!

Uni grabbed the bed and dragged it with one arm towards her, making me get my legs on the mattress in the process!

She got on me, cowgirl style. She took hold of my arms, pinning me down. I couldn't move her arms one inch, no matter how hard I struggled! I don't think it would be an exagerration to say that Uni's strength rivaled that of a gorilla or a bear! A gorgeous, sexy, blonde bear!

She leant and stuck her lips to mine. We made out for a while. I loved it! For all the pain she had caused me, her scent was so intoxicating.

She descended and started sucking my neck. Somewhere during that time, I managed to suck her neck a little too, giving her hickeys.

She let go of my arms and placed her palms on my chest while kissing and sucking it. I tried to release myself once more, but, even with her palms on my chest and my arms free, her hold was too strong for me.

The girl kept descending, sucking my belly, licking the tip of my penis and my balls while shooting me sexy glances, groping and kissing my legs, sucking my foot bridges and, finally, kissing my soles.

As much as I was enjoying it, it was not fair. I wanted to explore her body too.

'May I ask you to turn us over?' I asked hesitantly.

The girl giggled and did me the favor, so I was now on top.

With newfound excitement, I leant and started kissing and sucking her boobs (tasting some of my precum left on them from the boobjob earlier), her silky belly, her endless thighs while shoving my hands under her and groping her gorgeous butt.

I wanted to explore every square inch of that fused body. But those boots were getting in the way. 'Umm, may I remove them?' I asked.

'Only if you show me how much you want it,' Uni gave me a playful look. And, getting a stern expression, she continued: 'Beg me!'

'Please, let me remove those fucking boots!' I pleaded, panting like a child whose parents do not let it eat its favourite candy. 'I want to take them off you more than anything in the world right now.'

'Okay, you can do it,' she tossed her head back and laughed carefreely.

I hastily threw her footwear away (no socks underneath) and started sucking and groping her lovely calves. I descended little by little, sucked her ankles and kissed her foot bridges while groping her soles.

All the while, she was giggling, partly because she was being tickled, partly with pleasure. I exploited her relaxed state at that moment and caught her by surprise, turning her over before she could use her monstrous strength to resist. She squealed in surprise.

I kissed and groped her back while untying her ponytail, causing her hair to spread around her shoulders. I groped her ass again. I kissed her buttcheeks.

'Want to burst into my rear door?' she turned her head and playfully asked.

'As much as I love that idea, right now, I prefer vaginal sex,' I answered and turned her over again.

'Then come in,' she said sweetly, raising and opening her arms and legs.

At that point, something occurred to me. I stroked my nape. 'Umm... to condom or not to condom?'

Uni sat up, eyes widened. 'Good question,' she said.

I didn't use condoms with Asuna, but I used with Leafa. So what was I to do now? And, first of all, could that fusion entity even get pregnant?

We turned to Seven. 'Umm, Seven, considering the fusion lasts only for half an hour, what will happen if I get pregnant?' Uni asked.

'Hard to say,' the little girl caressed her chin.

I tried some guesses: 'Maybe the pregnancy will be cancelled along with the fusion when the fusion time runs out. Or maybe the pregnancy will be randomly transferred to either Asuna or Leafa.'

'Nah,' Seven commented. 'Most likely, the two girls will remain pregnancy free, but, every time they fuse, the fused girl will return to the same state as the previous time, so, after about 1400 fusions, she will give birth to a beautiful newborn!'

All three of us sweatdropped. Uni and I looked back at each other. 'Whatever, just shove it in me without a rubber,' she said.

I drove my reproductive organ in her vagina, the girl tightening arms and legs around me.

We fucked, and fucked, like there was no tomorrow. (Well, in a sense, there was no tomorrow for Uni indeed, since she would cease to be as soon as the fusion time ran out!) Those moans of hers were music to my ears, sounding like Asuna and Leafa screaming with pleasure at the same time!

We began in a missionary position, we started rolling after a while, moaning in each other's mouths, and ended up with Uni riding me cowgirl style.

'I'M CUMMING,' Uni screamed at some point.

'Me too!' I cried. 'Let's do it together. Three... two...'

Before I could speak the word 'one', the fusion time ran out! Uni's clothes vanished and Asuna's and Leafa's clothes appeared, scattered around in the room on random spots. The nude Asuna and Leafa were pulled away from each other and fell off the bed before they could orgasm; at the same time, my poor penis was left ingloriously alone, convulsing like a hose and spraying its cum on my belly as I was crying in disappointment.

'NOOO,' Asuna and Leafa sat up on either side of the bed and extended their arms towards me, as a desperate and futile gesture.

Now everything was quiet. I was lying on my back, panting after the inglorious, unwelcome orgasm, while Asuna and Leafa were sitting on the floor, their respective backs leaning against either side of the bed, hugging their knees in disappointment.

Seven stood up, having finished her notes. 'Well, that was an interesting experiment,' she commented.

Ignoring her, Leafa crawled over to Asuna. The two girls exchanged whiny, childlike looks.

'How about we console each other?' Leafa tentatively caressed Asuna's shoulder.

The redhead nodded with a playful sob.

The two girls initiated a scissoring lesbian session on the floor. I sat up, watching them lazily, not having recovered from my orgasm yet. Seven sat next to me. 'Same old, huh?' she commented.
