December 26, 2017... Chaldea..
Koyanskaya was walking around the place her high heels making sound with each step, a brown hair boy with a jacket, white shirt, jeans and white shoes is walking beside her. That's was her master name Issei hyoudou, he doesn't know how he got himself into this mess maybe summoning a hot fox girl? We don't know yet if Issei now that's she isn't a fox girl.
"Do you think is a good idea to fooled the guy who bought this places.." has Issei said with a nervous tone his brown eyes darting to serval dead body that was laying around with blood still coming out "oh.. oh master don't be afraid.. just a little betray doesn't make me that bad..❤️" she said teasingly to him, "now master! We better get going we don't want to make Rasputin mad❤️" has she said before walking away from the place has Issei follow behind her.
Grigori Yefimovich Rasputin, a weird Russian man who was summon by the alien god to destory humanity has there was blood on his hand after killing Da Vinci he was looking for the remaining survivors that was Mash, Ritsuka and Goredolf. Koyanskaya was walking around the corridor of chaldea has Issei is still walking behind her, without anyone there they walk back to Rasputin make it clear that no one was alive inside of the chaldea.
After hours passed mostly the remaining survivors escaping by a car, that was made by a smaller Da vinci. Koyanskaya just sigh in annoyance has Issei look at the car "should.. should we chase them?" He ask her "no my sweet master.. just let them go.. for now❤️", "Mm ok Koyanskaya.." he said to her before they walk back to the place maybe meeting them in Russian Lostbelt
—————————————
Inside of the Russian Lostbelt Issei was wearing snow jacket with the NFF logo on the front of it, has he wear a small hat to cover himself even more, koyanskaya was too wearing a Jacket has she's look at Issei patting his head. "Master.. are you ready?" She ask in a sweet tone of voice before grabbing his hand and walking together, still wearing those high heels she doesn't feel cold has Issei wears boots.
Her Mana reserves was large, massive enough to fill a entire country with it but it can end fast when doing something that's important or impossible, Koyanskaya looks at Issei his body was strangely always pack full with mana has she walk closer to him "Master.." she ask him, Issei would look at her has he titled his head. "Is something the matter koyanskaya? What's with that face.." he ask her looking at the weird face that she was making.
Putting her hand and making a circle before opening her mouth before slowly moving forward and backwards mimicking a blow job.. "eh? What's that supposed to mean.." Issei ask innocently without knowing anything about sex or anything sexually "Wow oh wow! Master is truly innocent and dense enough to not know that!" Koyanskaya said has she look at Issei with loving eyes. "How about I show you how to dump your mana inside of me.." she said in a lewd tone.
Before Issei can process that his hand was grab by her has they were dragged into a cabin that was made for koyanskaya since she's pay alot of money to build.. like one million? But that doesn't matter to her the only thing matters is getting mana now. Even though they can do it by blood is nothing pure useless and too little mana, his Semen that was a powerful source of mana.
Issei lay on the edge of the bed has Koyanskaya is beside him has he jacket and pants was remove showing tone muscle and arm he isn't strong but above average of strength, Koyanskaya purr at that before looking at the final piece of clothes his boxer. Laying down has she right between his crotch area smelling the musk of his dick in it "ough.." Koyanskaya moan a bit at that smell has she slowly started to see how massive that thing, "We got our self someone big.. very big.." Issei blush that sentence before fumbling his finger around her head "I'm.. not that big.. just average at best.." the boy down play his own size has he doesn't like to talk about it that much.
"Average at best..? Oh no your not average at best.. your just.. perfect size for me" saying that she remove his boxer a bit before suddenly the dick hit her face TWHAP! Has she blinded by the massive amount of meat in the way "Mm just perfect.." she said before slowly getting away seeing the massive Twelve inches cock and his apple size balls. "Ah.. ah.." moaning slowly Issei sees her mouth and tongue cleaning his cock making a small blow job to him, "ah~" has she drag her tongue up and down the cock tasting the salty flavor of it has small but large chunks of pre cum falls on to her and the floor too, she look at the tip of his bitch breaker clock before dropping her head on it.
"Oo.. such a big boy.." has her voice vibrate around his cock shaking Issei a bit has he drop on the edge again has she slowly pulled out and put back in has the pre cum started coming in fast dropping into her mouth has he drink ever last one of it. She suddenly ramp up the speed chocking on his cock a little "GWOH GLLACK" has Issei moan louder "ah! Ah!" Has he slam it deep inside making her neck obscenely bulge her slender neck showing his cock has her chocker snap at the roughness of issei *SNAP* has it drop down on the floor
"..I'm close.. Koyanskaya.." has Issei said to her, he slowly want to remove this pent up lust made by her has she does her job chocking on it even more "GWOH GLLACK GOWK" she only chock on it has a response before suddenly a large burst of cum suddenly cum.
Koyanskaya eyes rolled up has she drinks ever last each of those thick drops of cum has more produce again and again until her belly started bloated at that sign, has cum dribble down her chin dropping into her large chest making a puddle with it, Issei huff in a low voice "..are we done..?" Issei ask her, koyanskaya pulled out "PWAH!" Has she lick her face before cleaning herself up "Mm yes.. my sweet master, or should I say.. husband..❤️" her mana started to refill again with that she grab his hand snapping her finger removing all trace of there sexual interaction ever happend "now your my husband.. don't be naughty and go with other women.."
Koyanskaya move her hand around his crotch feeling the monster inside of it "hehe.. don't worry I'll be asking a lot of mana from today now.." Issei just blushes at that has the servant he summon was now his wife.
