Disclaimer: I do not own the Fate series or any of its characters.

Author's Note: So…I've learned NTR can go both ways, which I can understand, but when it comes to Yuri, I feel kinda sad. XD But…this came to mind the more I thought about it. So…hope you all enjoy this 2 part story.

Mash wakes up and finds herself in a strange room with her arms bound above her. She looks around in a panic, trying to find out where she is and how she got here. Just then, there is some clacking of high heels coming her way, making the demi-servant look up. The figure reveals herself in the light, wearing a leather leotard with thigh high boots and elbow gloves. Mash gasps as she recognizes the figure.

"S-Saber Alter!?"

"Correct," the dark king replies, tapping her riding crop on her palm. "And it's time for me to teach you a lesson, my dear demi-servant."

"Why'd you bring me here!? Where's Sempai!?" Mash demands.

"Let's just say…she's being taken care of as well," Saber Alter says. "Just like you're about to be."

"She better be alive…!" Mash grits her teeth. "Or else I'll-"

"Fufu! Do not worry~" the dark king gently tips her chin to her level. "Your master is fine. Do you want to see it for yourself?"

Mash looks over at the other side of the prison where she's at. A little window where she can see just a little bit. Ritsuka-chan is naked, in a Cowgirl position with an unknown man and with two other men surrounding her, presenting their dicks to her. Mash's eyes widen in shock.

"Sempai!? SEMPAI!" she cries. "Nooooo! Why!? Why would you-"

"She can't hear you," Saber Alter says. "These windows are sound proof and you can only see one way. Your master doesn't even know you're even here when she's captured."

Mash grits her teeth and looks down at the floor. She's doomed to rot in this place…and get screwed by a couple of guys if Saber Alter sends them in? Come to think of it, she's been getting a little…hot. Why though?

Saber Alter chuckles. "Seems like this drug is taking effect."

"Wha…?" Mash questions as she looks up.

"See…I rubbed some aphrodisiac on you while you were asleep. It will take effect within an hour or so. And it seems that it's working."

"Th-there's no way you put that kind of stuff on me…" Mash denies.

"Oh~? Shall we test it out and see?" Saber Alter goes up behind Mash and gropes her breasts, making her jump a bit. "Ahhhh! See how sensitive you are already?"

"N-no…it doesn't….feel that good…"

"Why aren't you resisting~?" Saber Alter coos in her ear. "Come on, your body is honest. Why can't your mouth be the same thing?"

The groping continues and Mash tries her hardest to endure it. She just wants to get out of here and fast so she can rescue Ritsuka-chan. Saber Alter lowers her hand to push aside her cloth and fondle her wet pussy.

"You're already this wet? You really should be more honest, my dear demi-servant~" the dark king coos.

"Please….just let me go…" Mash begs. "I want to be with Sempai. I love Sempai…so please…"

Saber Alter grins and leans against her. "Alright. How about this: if you can endure my pleasure for at least a week, I will let both of you go. You can handle this…right?"

Mash nods. "If it's for my Sempai, I will accept your challenge!" A week shouldn't be so bad as long as she keeps her mind at ease and thinks of Ritsuka-chan the whole time.

"Very well then," Saber Alter says. "Let's get started." She unties Mash and puts her on the bed in the corner of the room.

Once Saber Alter sits next to her, she does her groping technique once again. She goes around in circles, then up and down. Mash tries to resist it, but she can feel herself sweat all over.

"Feeling good so far~?" Saber Alter coos.

"It...it still doesn't feel good..." Mash replies.

"Ohhhh it will soon. You shouldn't really lie to yourself. Listen to your body a bit more~"

Mash grits her teeth and closes her eyes. She vowed to herself to put her mind at ease and not think about anyone other than Ritsuka-chan. It's day one, so she will be able to do that. However, she wonders if she'll really be thinking about the cute redhead when the week passes. This drug is really taking effect now.

"Hey...look at me," Saber Alter whispers as she gently tips her chin to her level after facing her and leans in to give her a nice, kiss.

Mash's eyes widen in surprise. She didn't really think Saber Alter would notice her trying to look out the small window. Saber Alter's tongue dominates hers right away, making soft moans. Mash lets out soft moans as well. Why? Why does this kiss feel so good? That kiss belongs to her Sempai, not her. The dark king multi-tasks by groping her breasts and then lowering her other hand to fondle her wet pussy.

"Mmmm...mmmm...,mmmchu...no...stop...!" Mash tries to stifle a moan.

"I will never stop~" Saber Alter says. "Don't forget our deal~" She fondles her pussy in a faster pace, making it hard for the demi-servant to resist.

Mash doesn't know how much longer she will be able to hold it in. She most likely is unable to anymore. She's reaching her limit already. "I-I'm gonna cumm...I'm cumming...!" she moans.

She screams in pleasure, throwing her head back as she climaxes. She squirts out love juices on the sheets with Saber Alter catching some of it and tasting it with her fingers. She licks her lips in satisfaction .

"Delicious~" she coos. "Some sweet demi-servant juice. Now then...let's move on to the main event, shall we~?"

"Eh?" Mash is gently pushed down on her back and has her legs spread wide.

Saber Alter pushes aside her cloth to reveal something between her legs. Something long, big and thick.

"Wh-wh-wh-whaaaa!?" Mash sputters. "Why do you have a...!?"

"Fufu! None of your concern," the dark king says. "All that matters is that I will make you feel good even more with this big cock of mine. Don't' tell me you've never had one of these things inside you."

The demi-servant shakes her head. "N-no..."

"Then it's your lucky day~" Saber Alter crawls toward her. "You get to lose your virginity from me. How exciting is that~?" She pokes Mash's wet pussy with the tip and then rubs it against her to tease her a little. "I won't enter you unless you beg for it."

"EH!?" Mash exclaims.

"Please, though I'm a dark king, do you really think I'm going to penetrate you without your consent~?" Saber Alter grins.

Mash is surprised by this. Saber Alter is an evil version of Saber. But...there is still good in her somehow. She's letting Mash decide whether or not she wants it. The drug is kind of cheating in a way, but regardless, she cannot resist the good feeling of pleasure after being touched and kissed like that. She needs more of it. And Saber Alter is the only one in this room who is willing to give her just that.

"Well~?" Saber Alter encourages her and keeps on teasing her with her dick. "I'm waiting~"

Mash cannot take it anymore. She spreads her legs wider with her hands and opens up her wet pussy. "P-please...give it to me. Give me...y-your cock. I beg you...to give it to me! Jam it inside me!"

Saber Alter chuckles. "As you wish~"

The dark king finally inserts her big, meaty cock inside Mash's pussy and makes her way deeper until it's all the way in. Mash's eyes widen at the thickness of this cock. She's never felt anything like it and yet...it feels so good just from it entering her.

"How does it feel now?" Saber Alter says.

"It…it feels really…good…!" Mash replies with a weak smile. "I don't know why, but it just does! Move your hips for me….I can't take it!"

Saber Alter nods while grinning. "As you wish~"

The dark king begins to move her hips nice and slowly at first. She leans over, looking down at the demi-servant while thrusting. Mash lets out several moans and cries with her limp arms at both sides of her head. She's completely vulnerable in this position, but she doesn't care. She NEEDS this feeling. She WANTS to feel good. Saber Alter holds her legs high as she keeps on thrusting, grunting with each movement.

"Your pussy feels so good around my dick~" she says. "It's like it's letting me swallow up my cock~"

"Yeeessss….yes….your d-dick feels so good!" Mash moans. "Keep going. Go deeper! Go faster! I don't care!"

"Heh, you're really loving it for sure~" Saber Alter grins. "You've already given up. Alright, I'll make you feel good until the end!"

She thrusts harder and faster just like Mash wants, making the demi-servant cry out louder, more moans are being heard. It feels amazing. There is nothing in this world that can make her feel this good. Saber Alter lets go of her legs and leans down to grope both of her breasts, plus nibble on her nipples a little bit to stimulate her a bit more. Mash throws her head back at this feeling, yet she loves still loves it. She doesn't want her to stop now. She feels like Ritsuka-chan back there with all these men, but it's just one on one for now.

"Mash…this is it…!" Saber Alter says. "I'm going to cum inside you! Tell me you want it! Beg for it! Say you want it!"

"Yes….yeeeessss…!" Mash cries. "Cum inside me! Please….I beg you! Fill me up with your semen!"

The dark king thrusts harder and faster until she gives one last very hard one and spills up her pussy with lots of semen. Mash throws her head back, crying in pleasure. When it's all over, Saber Alter pulls away and the remaining semen drip from Mash's pussy onto the sheets. The demi-servant is exhausted already.

Saber Alter grins and licks her lips. "It's not over yet, Mash. You still have 6 more days. Do you think you can handle more of my pleasure before I release you both~?"

Mash is too exhausted to speak. The dark king shrugs and tenderly picks her up to embrace her.

"Do not worry," she says. "For now, I'm here for you. Your beloved Master is too busy being horny with the boys in the other room. So until then…"

**A Week Later**

Mash feels like she's on fire. After endless pleasure day after day, with Saber Alter using different methods to make her feel good like using sex toys, tying her up on the bed and having sex with her at the same time, touching her like there's no tomorrow and so on, Mash cannot live without anything other than pleasure. Her mind has been broken now. Saber Alter wants to pat herself on the back. Her plan has worked.

"Ohohoho~" she chuckles. "Look at you. Masturbating on the bed while crying out my name. You really are a slut, aren't you~?"

"Yes….yeeeesss….I am a s-slut. I am a servant to only Saber Alter. Not anyone else." Mash says.

"Your final hours are almost up," the dark king says. "After you cum, I will gladly release you and your Master."

Mash gasps softly. Sure she wants to get out of this place, but after a week in this prison…does she really want to? Saber Alter grins at her reaction. There is absolutely no way Mash will want to leave now.

**Later**

Ritsuka-chan puts on her usual clothing, sighing in relief. She doesn't know how long it's been since she was locked up, but someone informed her that she is free to go. A guard leads her to a large room with double doors. With a nod, he smiles and leaves, having Ritsuka-chan go in by herself. But when she opens the doors, she is greeted by several of her female servants giving in to pleasure by lots of men and women around them.

"Wha….what is this…!?" Ritsuka-chan gasps.

They look like they are having fun. Like they are under some kind of spell that no one is able to break. Ritsuka-chan can see they are enjoying it a lot. Her female servants: Artoria "Lancer Saber" Pendragon, both Jeanne and Jalter, Ushiwakamaru, Quetzalcoatl and even the goddesses, Ishtar and Ereshkigal. The redhead cups both hands to her mouth, seeing this scene before her. Why didn't they let them go?

"Ahhh, you're here, Fujimaru," Saber Alter says from behind.

Ritsuka-chan turns around to see the very person she wants to see…being given the same exact treatment like the others, except Saber Alter is doing the job.

"Sempai…ohhhh…." Mash moans as she is being taken from behind, stand up doggy.

"Mash…!" the cute redhead is shaking. Her legs begin to feel weak. "I thought…I thought we're going to get out of here together! The guard told me so!"

"Mmmmm….does it look like she wants to leave~?" Saber Alter says. "I'm pretty sure that Mash wants to stay here."

Ritsuka-chan can see Mash's face. Her eyes are rolled at the back of her head, tongue is sticking out and her moans are loud.

"Mash…please tell me it's not true…!" the redhead cries, putting a fist on her chest.

"I'm so sorry….Sempai…" the demi-servant says. "Ahhhh….ohhhh…but this is…amazing! You have never felt…anything like this before. Saber Alter has taught me many things. Even though I loved you…you will not be able to satisfy me like she does. There is…just no way…"

"That's right~" Saber Alter leans over to kiss her on the cheek and goes back to thrusting, harder and faster this time. "Tell her everything. Do you want to be with your Sempai? Do you want to get out of this place? Do what your heart tells you~"

Ritsuka-chan shakes her head roughly and takes a step forward, putting both fists on her chest. "NO! Mash, don't listen to her! She's warping your mind!"

There is a slight hesitation before Mash responds. Her long bangs hide her expression. "I'm sorry…Sempai…but…" She looks up with a silly grin on her face. "There is no way…I am getting out of here! It feels too good! I don't want to miss this incredible feeling!"

"Haha! That's right! THIS is your home now! Your family is with these people in this very room~" Saber Alter grips onto her butt cheeks and thrusts even harder than ever. "You can experience this incredible feeling every single day! That's what I like to hear~!"

Ritsuka-chan drops to her knees, unable to look away. Her beloved demi-servant…has been taken away from her.

"Look at me, Sempai!" Mash says. "Watch me as I climax in front of you. This is what I've been waiting for all this time~! For you to see the results of my training!"

Saber Alter keeps up these hard thrusts until she can no longer hold it in. "This is it, Mash! I'm going to cum inside you once more…in front of your beloved Master! I'm cumming!"

"Cum….inside….insiiiide….yeesss…" Mash's eyes roll at the back of her head again, tongue sticking out. "Inside meeeeee….pleease….!"

With that, it is done. Saber Alter ejaculates hard inside her, spilling as much semen as she can with Mash crying out in pleasure. Ritsuka-chan can't watch any more of this. She tries to look away with her eyes closed, yet a gentle guard, who has been standing by her without her noticing, encourages her to look up, putting his hand on her head. Tears fall from the red-head's eyes as she sees Mash fall face down, butt up. Her body is twitching and she is panting heavily.

Saber Alter grins and walks up to her to kneel down to her level. "Well, Fujimaru. I guess it's up to you now. Do you want to stay as well? Experience what the others are experiencing right now? Or go free?"

Ritsuka-chan hesitates a little. She feels that there isn't any choice. Without her powerful servants, including her main one, she's powerless against whoever she encounters. Looking down at the floor, fists clenched and all, she finally speaks.

"I'll…I'm going to stay…" she says. "Teach me…everything…like how you taught Mash."

A/N: I still feel kinda bad considering it's Yuri NTR, but I made it this way. Hehe! XD Part 2 awaits!

Have a nice day!
