Before I could panic and start screaming again, the ghost showed me his palms as a comforting gesture.

He was a boy with white hair and black eyes. He was wearing an orange t shirt and blue jeans.

'Wh-what do you want from me?' I stuttered.

The spirit opened the door to my room and beckoned to me.

'You want me... to follow you?' I gulped.

The spirit nodded.

I followed him in my room. Lisa was snoring undercover.

We walked over to my room's window. The boy pointed outside. I gasped. Was he pointing at... Lisa's underground bunker?

'Is what you're looking for in there?' I asked. 'But how am I supposed to enter? The entrance is electronically locked. Only Lisa can enter there. She built that place for her experiments.'

The boy nodded, as if he already knew all that stuff. He looked at me strictly and pointed again. The message was clear. I had to find a way in there.

But, wait a minute. If that boy was a spirit, why didn't he enter himself through his ghost powers? And what would I find in that place? And who was that boy? Darn, so many questions.

Over the following days, I mulled over all that stuff, trying to reach a conclusion. There were nights I couldn't sleep because of that.

One of those nights, when I was sitting on the couch in the living room, hugging my knees, the door opened.

A shadow sneaked in. Was it another spirit? No, wait, spirits don't enter that way.

I turned on the lights. 'LUNA!'

'Ssshh. You'll wake everybody up, bro,' she whispered, anxious, in her usual, British accent.

As most of the times, my 15 year old sister in that universe was dressed in purple: a t shirt with the design of a skull on the chest area, a skirt and boots. She had short, dark brown hair and black eyes.

'Sorry,' I apologized.

'Why are you awake anyway?' she asked.

'You know... just... couldn't sleep...' I stroked my nape. 'Lotsa things in my head.'

'I understand you,' she chuckled. 'I just returned from a concert I went to in secret, because mom and dad wouldn't let me.'

She sat on the couch and removed one of her long boots in an unbelievably sexy fashion. 'God, I'm so tired,' she moaned.

I gulped. 'Umm, I can help you take off the other boot,' I offered.

'Okay, thanks,' she winked.

I knelt in front of her and slowly removed the other boot while kissing and groping her calf and finally her foot (she wasn't wearing socks)!

I swear I hadn't planned this! I got carried away!

'KIRITO!' she cried, almost waking up the whole Loud family.

'Sorry,' I gulped, red like hell.

She glared at me. She seemed so angry.

'I swear I didn't mean to...' I tried to defend myself, awkwardly, like the 12 year old I had transformed into a few days earlier, like the 12 year old I was in my heart too by that time. 'I can understand you if you want to punch me in the face. I won't hold a grudge...'

Luna laughed. 'Let's go to my room and we'll discuss it there,' she proposed.

And so, we went upstairs, Luna holding her boots and tiptoeing. So sexy!

In her room, Luan was snoring. Luna sat on her bed and patted on the spot next to her. I sat tentatively.

'I understand you're in an age your body starts changing and your hormones go crazy,' she said sweetly. 'I've been there. In my case, it was even harder, since I'm... you know... a lesbian.'

'A WHAT?' I cried, almost waking up Luan.

I was genuinely surprised. Most of the girls I had been with in the past had lesbian urges, but that was the first time I met a 100% self aware, self admitted, outright lesbian.

'Don't tell me you never suspected anything,' Luna raised an eyebrow. 'I've been dating Sam, a girl from my school, for almost one year.'

Come to think of it, I had read something about that in my other self's diary. But I couldn't remember everything I had read in that diary.

I looked her seriously in the eye. 'It's okay to be gay. Never be ashamed of it,' I said and affectionately caressed her knee. Whoops!

'Sorry,' I blushed and removed my hand.

'No, it's okay,' she smiled, took my hand and placed it back on her knee!

My eyes widened. I gulped. I looked at her, with a lost expression.

Luna wrapped her hands around my neck and stuck her lips to mine. We started making out, me hungrily groping her knee and thigh.

My sister broke the kiss. 'Just to make it clear,' she raised a finger. 'I'm homosexual and Sam is my girlfriend. You're just my cute, little bro whom I'm training. Okay?'

'Okay,' I nodded with a smile. 'Don't worry. I won't cause problems to your relationship.'

'Good,' she smiled.

We resumed making out.

Eventually, I drove my other hand under her skirt and started taking out her underpants. My sister lay down on the bed to help me remove it.

'My turn,' she said, sat up and removed mine, leaving me naked.

She opened her legs. 'Wanna come and explore?' she asked playfully.

'Yes!' I cried.

I drove my little head under her skirt and started sucking her virgin (at least in terms of heterosexual relationships) pussy. She gripped the mattress with her fingers and toes and started producing moans.

At some point, Luan was heard: 'Mmm... how do you fit 4 elephants in a car...snore snore... mhahaha, good one...'

Alerted, I took my head out of Luna's skirt and looked at the redhead. She was wearing yellow pajamas and seemed asleep.

'Ignore her, bro. She's just sleep talking, as usual,' Luna whispered.

We resumed. Luna slowly removed the rest of her clothes as I explored her naked body, which was slowly being revealed before my eyes.

Later, when we had progressed and we were fucking in a missionary position, me sometimes sucking her elegant neck and sometimes her gorgeous breasts, Luan spoke again: 'Mmm... I want sex too... snore snore... I need brotherly dick...'

We interrupted and turned to Luan again. Had she said... what I had heard?

Luna chuckled. She gently pulled my cock out of her and crawled over to Luan's bed.

Then, she removed the blanket and began... undressing Luan! While kissing her on the neck and other body parts! Luan was moaning and smiling in her sleep.

'What are you doing?' I whispered, freaked out.

'Let's give our sleeping beauty what she wants,' Luna winked.

Luan was quivering, unconsciously helping Luna remove her pajamas and underwear easier. I saw the redhead's gorgeous naked beauty being revealed little by little. Her large breasts, her belly button that looked like a work of art, her gorgeous, freshly shaved legs, her pussy that was inviting me to...

'Luna, no!' I snapped. 'If we do that to a sleeping person, it's rape!'

Luan opened her eyes wide and glared at me! 'Am I awake enough for you now?' she snapped, angry with impatience. 'Now bring your tiny but cute dick over here and fuck me!'

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

Luna, Luan and I were now all nude. We were fucking sideways, me thrusting my little dick in and out of Luan's pussy, sometimes making out with her, sometimes kissing her breasts or neck. At the same time, Luna was behind me, gripping my shoulders and rubbing her pussy sometimes against my back and sometimes against my ass.

'Fuck us, bro,' Luna gasped.

'Fuck is like the sluts we are,' Luan added. And then she laughed herself at that remark, amid her moans and screams!
