Chapter 19: Behind Enemy Lines

"Sirzechs... Got used to your new body?"

Lucias asked while checking the supply of food and potions in his inventory. Making Sirzechs nod her head before taking out a black coat from the chest in front of them. 

"How long until we arrive at our destination?"

She asked causing Lucias to raise 5 fingers at him without turning his head. 

"5 hours?"

"No, 5 minutes... That's why everyone wear your invisibility cloak. We'll commence the drop as soon as we enter enemy borders"

He said while Rias and Venelana tried to calm their emotions down since it will be the first time that they've been assigned with an extremely dangerous and crucial mission.

"Nervous?"

Lucias asked as he placed his hand on top of Venelana's hand. Making him feel her cold hands due to the nervousness that she felt, since one wrong move could lead to their deaths.

"Don't be so nervous, I promised to protect you both when I dragged you in this mission... Since there's three of you that can control the [Power of Destruction]. We can finish this mission within two days... As long as you all can keep up with my pace"

He said before looking at Sirzechs with a teasing smile on his face.

"So... Tell me what happened with Issei"

He asked while looking at the obvious red marks on the fair skin of her neck. Making her blush as she hurriedly hid the marks on her neck with the black cloak in her arms.

"You tricked me!!"

She shouted with a furious expression on her face. Clenching her teeth as she remembered what happened yesterday. Making Lucias grin in response.

"Really now... Sandra said you enjoyed your session together"

"Y-You!!"

Sirzechs said as the scene from last night appeared on her head. 

-Flashback (yesterday)-

"So you're saying... Sirzechs obtained a few of my own emotions and characterics?"

Sandra asked while crouching down with Lucias at the wall to ensure that no one would hear their conversation.

"Yes... she got the skill [Heightened Sensitivity], and from her reaction a while ago... I think she also obtained your love for Issei... So her personality right now is a mix of yours and his own"

He explained before both of them glanced back at Sirzechs who was sitting on the couch.

"So she also likes Issei, huh?"

She said before an excited smile appeared on her face. Making Lucias look at her with a weird expression on his face.

"Why the hell are you excited about another woman looking your own husband?"

"You don't understand, Lucias. Succubus grows stronger by the number of partners that they have on a regular basis... but after I got together with Issei. I stopped... That's why I'm having a hard time increasing my own strength"

"..."

"I still need to feed so I regularly just blow them so that I'll get the essence that I need... and most of the time, if I am sexually frustrated, I just invite other succubus from our faction and do it with them"

"... I forgot that most succubus are bisexual"

"Aren't you also bisexual?"

"... Kind of"

Lucias muttered as the image of Modeus suddenly appeared on his mind.

"How about Modeus? She only has me as her partner so how come she's still able to increase her strength"

Lucias asked with a frown as a trace of fear and anxiety appeared in his eyes.

"Oh, that's because she's been doing it with the other girls of your harem. She developed a toy moulded from the shape and size of your p*nis. She was using it together with the rest of the girls of your harem. But don't worry, you are her only male partner. She doesn't even like other males touching her, you're the only exception"

She explained. Making Lucias sigh in relief before a sudden realization entered his mind.

"Wait... what toy?"

He asked causing Sandra to look at him with a weird expression on her face.

"You don't know?"

"No..."

"Then do you know the reason why your fiancée are giving out plushies and toys of you 5 years ago?"

She suddenly asked, causing to Lucias look at her in confusion.

"It was made to control the 4 races in the faction that you seduced... The Sirens, Lamias, Harpies, and Flügels... They had to since they've been annoying Asia to have a chance to mate with you"

She explained while Lucias listened to her intently.

"The toy that I mentioned before was an exclusive product in your harem... but I heard after the war started, that toy was given away to the Sirens who always used it with each other everyday"

She said. Making Lucias look at her in disbelief, opening and closing mouth like he was about to say something but decided to just leave it. Since it was already done anyway.

"let's go back to the topic from before... What do you want to do with Sirzechs"

Lucias asked. Making Sandra grin in response.

"I want her to join, Issei's harem... That's why please help me, Lucias-sama!!"

She said as she tried to kneel down in front of Lucias but was quickly stopped by Lucias who pushed her head.

"Is Issei alright with this?"

"Don't worry, I'm sure he'll love it!"

"..."

"Even though Issei completely trashed his dream of becoming a harem king. He still does want a harem... It's just that he didn't do it as a sign of respect for me"

She said with a bright smile on her face, causing Lucias to look at her in suspicion.

"... So how do you want me to help?"

"I want you to get Issei drunk, and I'll handle everything after that"

She said. Making Lucias contemplate as he tried to decide whether or not to help her in this charade.

"... Then I also want something from you..."

He said as he leaned closer and whispered something in her ear. Making her slightly frown from his request before nodding her head in understanding.

"What are you two talking about?"

Sirzechs asked as he noticed both Sandra and Lucias whispering to each other at the corner of Issei's house. Making both of them stop before they looked at Sirzechs with an innocent smile on their faces.

"I don't have any extra rooms at the ruby palace right now, so you'll have to stay here. I already talked with Sandra about this and she agreed. Is that right, Sandra?"

He asked, causing Sandra to brightly smile in response.

"That's right, you can stay here. We have plenty of extra rooms after all, so you can go ahead and sleep at Iss- the guest's rooms"

Sandra said as she wrapped her right arm around her waist and proceeded to guide her towards the second floor. Winking at Lucias who gave her a thumbs up. Taking out a strong liquor from his inventory before making his way towards the living room where Issei is currently staying at.

"Where's Rias?"

Sirzechs asked as she was being dragged towards a room at the 2nd floor of their house. Looking around the interior of the house.

"Rias? She's staying with Venelana at the Ruby Palace, so you don't have to worry"

She said before pushing Sirzechs into their bedroom. Trying her best to hide the mischievous smile on her face.

"... This is a guest room?"

Sirzechs asked in suspicion, noticing the king sized bed in the middle of the room while a pack of condoms is placed beneath the lamp just beside the bed.

"... I think... I'll just sleep on the sofa..."

"How can we do that to a guest!? This is your room, we'll staying at the room beside this so if ever you need anything... just knock on the walls and we'll know"

She said pushing Sirzechs to sit down on the bed, before Sandra placed a chair in front of her. 

"W-Why is there a chair in here?"

"Oh? Don't worry, it's just something that Issei and I use when exercising..."

Sandra said as she sat down on the chair. Facing Sirzechs with a wide smile on her face, causing her to feel uneasy.

"W-Who's room is this?"

She asked out of curiosity as she placed her hand on the pillow, causing a familiar comfortable and masculine scent to assult her nose. 

"This is Issei's room when we still slept seperately. It's been a while since I properly changed the pillowcase, so I should change-"

"NO!!"

Sirzechs suddenly shouted, causing her to immediately cover her own mouth in surprise since she didn't expect herself to answer like that.

"Hmm?"

"I-I'm already fine with everything. No need for the trouble"

"But I'll feel bad if I don't-"

"It's alright... I like this room"

She said with slightly flushed cheeks. Making Sandra smile before she suddenly held her hand.

"Sirzechs-san, what do you think of Issei?"

She asked, causing Sirzechs to jolt in surprise as she didn't expect to be asked that kind of question so suddenly.

"H-He's a good guy..."

"Is that it?"

Sandra said as she suddenly leaned closer to her ear before whispering something to her in a soft voice.

"Do you love him?"

She asked. Making Sirzechs grow increasingly red down to her neck.

"D-Don't joke like that, we're both guys. Why would I love my sister's previous pawn?"

Sirzechs hurriedly said. Making Sandra show mysterious smile at her direction.

"Is that so..."

She said before standing up from her chair.

"It's already late, so I'll leave for now. If you need anything don't hesitate to call me alright?"

She said, causing Sirzechs to nod her head as she watched Sandra leave the room. 

"... Why do I feel like they're planning something strange?"

She muttered before glancing at the alarm clock at the side of the bed.

"... I hope everything would go well tomorrow..."

She says as she laid down on the bed to go to sleep. Placing a picture of Rias and Milicas together at the top of the drawer beside her with a gentle smile on her face.

"Goodnight"

She said. Removing her shoes as she stretched her body. Preparing to sleep soundly on the bed who was littered with Issei's scent.

"... It smells... a bit nice... W-Wait, what am I saying!? I'm a guy..."

She said while burying her face on the pillow. Making her body heat up, feeling her crotch itch as Issei's scent continued to enter her nose. 

"I can't sleep like this..."

She said before someone suddenly opened the door. Making her jolt in surprise before hearing the person slam the door shut behind him.

"I-Issei? What are you doing here?"

She asked. Staring at Issei with a cautious expression on her face.

"... Sandra?"

Issei guessed while looking at Sirzechs' with flushed cheeks. 

"I'm not-"

She tried to deny but was interrupted as Issei suddenly pinned her on the bed.

"Issei, what are you doing!?"

She shouted as she tried to push his body off of her. But failed as Issei started to kiss her neck, slowly making her way up to her lips.

"... Sandra... Can we?"

He asked as he started rubbing Sirzechs' crotch above her underwear. Making her body tremble as a wave of pleasure assulted her mind.

"Issei..."

She called in a dazed voice. Making Issei kiss her on her lips, inserting his index and middle finger inside her entrance.

"I can't... hold it anymore, Sandra"

"mn..."

She answered in a muffled tone before Issei started taking off her clothes. Making Sandra, who was listening from outside the door to show to smile victoriously.

"... It's a success... the only thing left is Lucias-sama's request"

She whispered to herself, recalling the requested that Lucias made before he agreed in helping her.

"Convince Rias to give up on me. She'll only hurt herself if she keeps pursuing me like this"

-Flashback end-

"Lucias-sama, where almost there"

The pilot reported, causing the 5 people inside the aircraft to immediately wear the black cloak around their body. Placing all of their radios hanging on their clothes inside the cloak. In case that they ger seperated during the drop.

"Everyone ready?"

Lucias asked. Making all of them nod their heads in response.

"Open it, and... thank for your services, soldier"

"Glad to be of service to you, Lucias-sama"

The pilot said in a respectful and calm tone, making Rias look at the direction of the speaker in confusion.

"Lucias, why did you-"

Rias says as Lucias suddenly grabbed her and the 3 girls in his arms before immediately jumping off the aircraft. Surprising the 4 of them from his sudden actions before hearing a loud explosion behind them.

"Lucias... D-Did he just..."

"It's impossible to enter enemy lines without getting detected... He already knew about this before we even set off"

Lucias said while looking at the Tier V Gastrea on the ground. Pointing it's long mouth to the direction of the aircraft from before.

"We're almost at the ground so... everyone prepare to seperate and spread your wings. Avoid using any magic or else they'll notice our existence"

(A/N: Moshi Moshi. Please don't cry anymore for the Yuri of the harem. I understand ? Capisci?!
