Shido's POV:

The morning sun's rays hit me through the window and stir me awake with a groan. Slowly open my eyes, I notice Tohka lying asleep in my bed with me, and everything from last night became clear. I really did have sex with Tohka...

Smiling, I gentle caress Tohka's head, running my hand through her hair. She lets out a quiet moan stirring at my touch, before fluttering her eyes open. "Shido...?"

"Good morning, my Princess." I greet her. "Did you enjoy your nap?"

"Mhm." She nods, a smiling forming on her face. "We really did it last night... I feel so happy."

"I am, too, Tohka." I give her another kiss, which lasts only for ten seconds this time. "Well, we should take a shower first. Don't want to start the day smelling like sex."

"Can I come with you?"

"Sure, why not?" Honestly, given I've just seen her naked, it shouldn't be a problem if we shower together.

After washing each other in the shower, the two of us get dressed and head downstairs, where we see Maria already making breakfast and Kotori sitting at the couch. "Good morning, Kotori. Good morning, Maria." I greet them both. Maria glances back at the two of us, and then immediately blushes and focuses back on making breakfast. Odd.

"Did you enjoy fucking, lovebirds?" Kotori asks. Yeah, she obviously heard us.

"Shido was amazing!" Tohka cheerfully replies.

"Yeah, I'm sure he was." Kotori says nonchalantly. "Guess Yoshino's right that cooking isn't your only skill." Okay, Kotori's acting a little strange. She might be jealous. Is this also about yesterday?

Maria is also acting a little weird. Even while we were eating breakfast, she would steal glances at when she thinks I'm not only, and when I catch her staring, she blushes and looks back at the food. "Maria, are you ok?" I ask the AI girl as we wash the dishes. "You've been stealing a few glances at me during breakfast, and you haven't spoken at all."

"M-My apologies for worrying you." Maria quickly apologizes.

"Did she see something embarrassing?" Tohka asks. "I hear that people act like this when they're embarrassed about something they've seen or done."

"My guess is that she peeked at you two having sex." Kotori accuses, and Maria immediately freezes.

"Wait, you really were watching us, Maria?!" I ask, surprised that she would peek at us.

"I-It was for research!" She quickly defends herself, her face blushing madly. "Yes! I did so to further my understanding of love!" Well, I guess that makes sense. She did say she wanted to observe my love interactions with the girls, and sex is the biggest step. Though, that still doesn't make it any more right.

"Yeah, and I'm sure you had a lot of fun masturbating to your new research material." Kotori says, sounding disappointed in her ship's AI.

"I didn't masturbate!" Maria blurts out. "I don't even know what that is!" Huh. Okay then.

"Maria." I call her name sternly, and she flinches and looks at me like a kid in trouble. "Even if it was to help in your search for love, it's still considered bad manners to peek at two people having a private moment, especially sex."

"... I'm sorry." Maria apologizes, this time looking guilty. "I will abstain from watching you have sex from now on."

I pat her on the head. "Hey now, I'm not mad at you. I just would rather not have anyone peeking at us during sex." I tell her, and she nods in understanding. "Anyway, we should head to school now."

"Very well." Maria responds, making me raise an eyebrow at her.

"Are you coming with us to school, Maria?"

"Yes. I am set to be a transfer student." Oh, that's interesting.

"So, Maria's going to be our classmate?" Tohka asks curiously. "That means we're all going to the same school!"

"Yes." Maria confirms. "It seems to be the best method of constructing necessary events."

We head outside and see everyone else already waiting for us at the entrance gates. "Darling! There you are!" Miku happily greets me.

"And Maria-san's with them, too." Kurumi notes.

"Question: Are you attending school today?" Yuzuru asks.

"Yes. I wish to broaden my scope of experiences." Maria replies.

"Right. You're here as a transfer student." Yoshino says knowingly. "You'll be seated in Shido's class, correct?"

"That's correct."

"Very well, then. You'll have to follow me and Natsumi to the faculty office."

"Are you attending as transfer students, too?" Tohka asks curiously.

"Oh yeah, you were with Shido, so you weren't filled in." Natsumi smirks. "We're actually the teachers."

"Teachers?" I blink with surprise. I mean, I kinda understand it. Yoshino is actually 40 years old and Natsumi has her adult form, they could both pass as teachers.

"That's right!" Yoshino chimes in. "These two are gonna give you a lesson you'll never forget!"

"Well, I'll be looking forward to it, then."

Yoshino and Natsumi went to the faculty office with Maria, while the rest of us went to our respective homerooms. I sit at my usual spot with Tohka and Origami sitting next to me, Kurumi behind me and Rinne in front of me. I can already feel the glares of the other male students, seeing me surrounded by beautiful girls.

"Everyone, attention please!" I hear Yoshino call out to the class. Huh, guess she's replacing Okamine-sensei while we're here. "We have a new transfer student us today. Please make her feel welcome."

Maria comes in at that moment. "I am Maria Arusu. Nice to meet everyone." She introduces herself to the class with a bow.

"Oh, I have a question!" Tonomachi raises his hand. "Where do you come from, Arusu-san?" Oh god, please don't answer-

"I moved here from Cairo in Egypt when I was very young. I have been living in Tengu City with my uncle for over a year now." Oh. Not what I expected.

"I see." I notice Yoshino looking at Maria with a smile. She must've given her a cover story so she wouldn't answer my house and start any unnecessary drama. "Then Arusu-san, you can take a seat in the back."

Phew, one major misunderstanding avoided! Thanks a bunch, Yoshino!

The morning sessions went by and it was time for lunch. Everyone else left, leaving just me, Maria and Tonomachi. "So, Arusu-san, how is Itsuka?" Tonomachi asks. "He hasn't done anything weird to you, has he? He's a real Lothario."

"Hey! Don't insult me while I'm still here!" I exclaim.

"I am fine, Hiroto Tonomachi." Maria replies. "If you are so worried about me, why not offer me a tour of the school?"

Tonomachi gapes. "Eh? Huh? Me? You mean me?"

"Yes."

His face beams up like a kid in a candy store. "I-I-I would love to! I, Hiroto Tonomachi, will do anything for you, Arusu-san!"

"I see. Thank you very much."

"Wooohooo! Finally, spring has come for me!"

"Easy there, turbo!" I frown. "She only agreed to a tour, not to be your girlfriend." But he was far too happy to listen and leaves the classroom with Maria. If anything I'm more worried about him than Maria, especially since Marina has the power to erase NPCs from the virtual world if they annoy her, according to Yoshino.

Well, guess I'm left alone to enjoy my lunch.

"Shido." Or, I was until I hear Kotori enter the classroom.

I turn to look at her as she walks up to me, carrying her own bento. "Kotori? Didn't expect you to come here. Did you need something?"

She's silent for a moment before responding. "I wanted to talk about something. Just the two of us. I ask Maria to modify the NPCs so no one will walk into the room while we're both in here."

"Um, okay." If she's going to such lengths to make sure we're alone, then it must be important. And I feel like I can guess what. "You can sit on my lap if you want." Kotori blushes heavily, but accepts my offer and sits on my lap.

The two of us silently take a bite out of our own bentos, and then Kotori speaks up. "Shido..."

"Wait, let me guess." I interrupt her. "Is this about what Yoshinon said yesterday?"

"... Yeah." Kotori quietly answers, looking down at her bento, before twisting her body around to face me, hugging into my chest. "Shido. What do you think of me?"

"Huh?"

"Before you joined Ratatoskr, you had always known me as your sweet, adorable little sister." She says. "But then, after you first met Tohka, I showed you a side of me that I've kept secret for five years, alongside me being a Spirit."

"Is that what this is about?" I ask, making her look at me. "Well, my answer is this: Black or white, it doesn't matter to me. Whether you're the weak, adorable Little Sister Kotori or the strong, pushy Commander Kotori, I love you all the same, and that has never changed!" My words make her gasp, and I take that moment to dive in and kiss her on the lips. She's shocked by this, but unlike last time, she instead relaxes and kisses back. The kiss quickly grows into a make-out session as she wraps her arms around my neck, our tongues dancing in each other's mouths.

After a full minute, we part from the kiss, a thin trail of saliva briefly keeping us connected. "Shido..." She softly mutters my name. "I love you."

"I love you, too, Kotori." I confess my love to her as well.

She leans close to my ear, whispering her next words. "Once you come back from your date with Maria, we'll continue where we left off."

Well, looks like I have something else to look forward to.

School ended and it is now late afternoon and I'm outside the house with Maria. "Kotori seems more cheerful compared to earlier today." Maria notes Kotori's happy demeanor.

"Oh, let's just say I promised her something special when we're done with today's date." I vaguely tell the AI Spirit. "Now, as for today, how about we go to the shrine this time?"

Maria smiles. "Yes. It's somewhere different, so I'm happy."

The leave the residence area and make our way to the shrine area. There are a few people around, but they aren't taking notice of us like last time. "I made modifications to the NPCs. They won't pay attention to us for this date." Maria explains.

"Thanks. I appreciate it." I thank her.

"Is there a reason why you're not fond of attention?" She asks with a question mark above her head. Oh, now that's cute.

"It's not that I'm not fond of attention. I just feel that if a boy and a girl are on a date, they have a right to some sort of privacy." I try to explain.

"You mean like when you and Tohka were having sex?"

I blush at the unexpected comparison. "Especially that. Please, don't bring that up again. Sex isn't something that should be talked about in public."

"My apologies. You make a valid point, however. I won't make further changes today."

We walk up to the shrine and there were some people writing on small cards, before putting them in a small box, and then praying and bowing. "Oh, I've heard of this." I say, expressing interest. "It's a tradition when it comes to believing in fortune and luck."

"Would you like to try it, Shido?" Maria asks.

"I'm willing to try it if you are."

The two of us write something down and place the paper into the box and then pray, before standing up and bowing. Afterwards, I notice Maria having a worried look on her face. "What's wrong?" I ask.

"Shido... would it be okay to lock arms while we walk?"

I smile at her request. "Of course. Hold on to me."

Her smile comes back. "Yes, thank you." I wonder why her smile faded for a moment. Could it have something to do with Marina?

Maria wraps her arms around mine and we walk away from the shrine in silence. "So, where do you want to go next?" I eventually ask.

"Let me see." She puts a finger on her chin in thought. "If we're going to have dinner, there is a restaurant that have been wanting to try. There is one at a nearby train station that offers a full-course special, popular among couples." That sounds like a place Tohka would want to go to.

"Sounds like a good deal to me. Let's go."

Maria then giggles. "That was a joke."

"Ah..." I blink. "You were trying to pull a fast one on me, huh? Well played."

"Thank you. I wasn't sure if I was capable of joking." Maria, ANYONE is capable of a joke, even AIs like you.

"So, seriously, where to next?"

She takes my hand. "Why not a place where the two of us can relax?"

I nod at her suggestion. "Sure. Let's head over to the forest lake. It's very peaceful there." She nods and we make our way to the lake.

There's an empty bench near the gazebo, so we sit down close and Maria rests her head on my shoulder. I could see that she wants to rest, so I join in as well and lay my head next to hers. Honestly... Maria really is a beautiful girl.

After a bit of time passed, the sun is setting and it would be dinner soon.

"Alright, let's head home, Maria." I say.

"Hold on a moment, Shido." Maria stops me for a moment and I turn to face her. "I had a very good date today."

"I'm glad it worked out." I smile. "Have you learned anything new this time?"

"Yes, the sky is beautiful at sunset." She looks at the setting sun with a smile. "It fills me with joy when I get to share it with someone."

I look at the sunset with her. "Yeah. It's always nice to be able to watch the sunset with the people you cherish."

"... Shido." She calls for me after a short pause, and I turn my head to see her looking at me, but no longer smiling. "Do you wish to return to the real world?"

Ah. Her question reminds me that she and Marina aren't real people. That the only times I'll be able to physically interact with them is here in the virtual world. Not to mention what's about to happen, and what I'll be forced to do...

No. We will find a way to save them!

"No." I answer firmly. "When I accepted the idea to date you, Maria, it was also a promise to you. I will not leave until I help you discover what love it. Until that day comes, I won't leave you, and I'll make sure you are loved."

"Shido..." My words do seem to cheer her up, but I can tell she still feels lonely. "Let's go home, Shido. We'll have another date tomorrow, correct?"

"Yep." I confirm. "It'll be another school day tomorrow, but I'll be free to see you after school." She smiles in response.

When we return home, the first one to greet us is an enthusiastic Rio, who promptly hugs me. "Papa! You're back!"

"Yep. I'm back, Rio." I smile, patting my daughter on the head. "Have you been a good girl while I was gone?"

Rio nods. "Mhm! Rio has been good!"

"Good to hear!"

"Welcome back, you two!" Rinne greets us, and I notice a bunch of delicious food on the table. "Since you came back late, I decided to visit and cook dinner for you."

"Thanks a bunch, Rinne."

As we sit down and have dinner, I catch Kotori giving me a glance. I give her a nod, and she nods back.

Warning: Lemon incoming! Skip if you feel uncomfortable!

Third POV:

The moment dinner was over, Shido and Kotori leave upstairs, entering Shido's room together. The moment they're both in the room, Kotori closes the door and locks it, and then pushes Shido to the bed.

"Whoa!" Shido yelps as he's made to sit on the bed. Kotori immediately straddles him and kisses him passionately, which the [Sealer] returns. This time, though, Kotori's clothes don't disappear, meaning she didn't do the Reiryoku trick like the three Spirits before her. That doesn't deter Shido, though, as he slowly moves his hands to his step-sister's ass, giving her panty-covered cheeks a squeeze and making her moan into the kiss. After a full minute, the two part from the kiss. "Well, aren't you eager?" Shido lightly jokes.

"I've been wanting to do this ever since I realized I liked you more than just us being step-siblings." Kotori says firmly. "No more waiting. It's time I finally got a piece of my Onii-chan~" Shido can't help but shudder from hearing her call him 'Onii-chan' in this scenerio.

The two quickly undress, and Kotori forces him to lie down on the bed as she crawls on top of him. "Miku, Tohka, and even Yoshino let you take control when you fucked them." Kotori says with a predatory smirk. "But now, you're about to feel what it's like for the woman to be leading." She moves a hand down to Shido's dick and starts stroking it.

Shido groans from the feeling of her soft hand pumping his dick. "It feels so hard on my hand right now~" Kotori coos. "Good~ It better be for what I plan to do." She then takes her hand off his dick and stands up on the bed, her full naked body on display for him. At this moment, Shido realizes that Kannazuki must be feeling really jealous right now.

She then raises her right foot and brings it down onto his dick, making him gasp sharply. "Hehe~ Haven't gotten the foot treatment yet, huh?" Kotori smirk, enjoying the feeling of his warm dick on her foot. "Well then, enjoy being stepped on, Onii-chan~" She presses her foot down on his dick and strokes it, making Shido groan underneath her. "Look at you, squirming powerlessly beneath me~ You're really enjoying this, aren't you?"

Shido can't deny that he is indeed enjoying this. This is his first time receiving a footjob, and yet the feeling of Kotori pressing her foot down on his dick with just with the right firmness, the way she uses her toes to stroke it, combined with her domineering attitude, makes it all the more pleasurable as he feels his limit quickly approaching.

"Are you about to cum?" Kotori smirks, feeling his dick quivering underneath her foot. "Are you gonna cum from my feet? Do it, then. Go ahead and let it out." She presses her foot down extra hard, and Shido groans as this triggers his release, his seed shooting out and covering him instead, making him shudder from being covered with his own semen.

Kotori laughs lightly. "You came a lot, Onii-chan~" She notes, enjoying the sight of her brother covered in his own semen. However, being the kind sister that she is, she decides to clean him up. Leaning down over him, she runs her tongue over his body and licks up the semen. Every moment of her wet tongue licking his body makes Shido shudder, the scenario arousing him as she cleans up all the semen. "Yummy~ Now, time for the main course."

Straddling his body once again, she lifts herself up and grabs his dick, lining it up with her pussy, dripping with her own arousal. For a moment, her dominant façade falters. This is it. This is the moment she finally gives Shido her virginity. Taking a deep breath to calm herself, she makes sure his dick is properly lined up, and then slowly impales herself on it.

"So... big..." She groans, feeling him part her walls.

"It's ok, Kotori." Shido comforts her, running a hand over her thigh to soothe her. "I'm right here."

Kotori gives him a shaky smile, and then drops herself fully onto his dick. She cries out from the stinging pain of losing her virginity, tearing up a little, but Shido leans u and hugs her, running a hand over her back to soothe her.

As they stay in the sitting position, waiting for Kotori to adjust, the younger sister suddenly reaches a hand up to her ribbons... and takes them off, letting her hair fall free.

"Kotori?" Shido says, surprised to see her take off her ribbons.

Kotori blushes. "I... wanted to bring back the time in Eden, when I was able to grow out of my ribbons." She says shyly. "So I decided... that when we do have sex, it would be without my ribbons. You don't mind... do you?"

"Of course not." Shido says, smiling with love and acceptance. "I love you, Kotori. With or without your ribbons." Hearing Shido say those words makes Kotori smile happily and the two share a quick kiss before Kotori pushes him back down on the bed.

Slowly she raises herself up, stopping when his dick is halfway out before dropping back down onto it with a moan. She repeats this process until she no longer feels any pain, and then begins going faster. "Onii-chan... Onii-chan..." She moans. "Your big dick feels so amazing~"

"Your insides feel amazing, too, Kotori." Shido grunts, holding Kotori's hips as she rides him cowgirl.

While there's still a bit of blood from Kotori losing her virginity, by now, his dick is slick with her juices that it's become a non-issue. She bounces up and down on his dick, moving her hips to ensure it hits her sweet spots. Meanwhile, Shido starts running his hands on her petite body. His left hand goes down to her ass and squeezes it again, while his right hand goes to her budding breasts, his thumb circling her erect nipple.

"Onii-chan..." Kotori whimpers. "My breasts aren't as big as the others."

"And they don't have to be." Shido assures her. "Remember, the first Spirit I had sex with was Yoshino and I enjoyed her, breasts and all."

"Ehe~ That makes me happy~"

Shido's hands soon shift and switch targets, his left rubbing her right breast while his right grasping her ass, this time helping her bounce on his dick. He soon becomes more active as he thrusts up to meet her bounces, her moan getting louder because of it.

"Onii-chan, I'm gonna cum!" Kotori cries out, feeling the rising heat in her pelvis.

"So am I, Kotori!" Shido grunts, feeling his own release fast approaching.

No words were said of if Kotori took the pills or not, because it's obvious that she did. Her bounces soon hit their max speed as both of Shido's hands go to her ass, preparing for their release-

-and the moment Kotori slams her hips down, Shido shoots up and takes her lips, kissing her at the same time as they have their mutual orgasm. Kotori's loving the entire feeling. From his seed filling her little womb, to his lips claiming hers, even the feeling of her Complete Seal forming from their love hitting its peak, the young Flame Spirit is experiencing what she, up 'til now, only secretly dreamed about.

Their mutual orgasms soon die down, and the two part from the kiss as Shido falls back down onto the bed, pulling Kotori with him. As they lie together and catch their breath, Shido uses what strength he still has to lift Kotori off his dick, letting his semen spill out of her pussy.

"Onii-chan~" Kotori sighs dreamily. "That felt amazing."

"Same here, Kotori." Shido says with a smile. His little sister gives him a tired, loving smile before lying down on his chest, and he watches with a smile as she quickly dozing off the dreamland. "Sleep well, my beloved imouto."

Reine's POV:

As Kannazuki and I are still working on things on our end, I notice him suddenly pause completely. "Hm? Is something wrong?" I ask him with the same stoic expression.

"I don't know why, but..." He starts speaking as he turns to face me, crying comically as he holds up a fist. "I feel so jealous right now...!" Ah, if he feels that way, then that means Shido just had sex with Kotori.

Now that I mention it, even though this is happening in the virtual world, I can feel the Complete Seals forming on their real-life bodies, meaning their love from forming it is powerful enough to affect their real selves as well.

How very interesting.

Another date done, another Complete Seal formed!

Yeah, Kotori did NOT take Yoshinon's words lying down. No way she was gonna watch from the sidelines while everyone else has their turn with HER onii-chan, damn it!

Also, I decided to make Kotori the dominant one for this lemon. Because, let's be honest, she's much better as a dom then a sub.

And yes, I couldn't resist that last scene with Kannazuki. It just feels like the cherry on top.

Anyway, see you guys next chapter!
