Fate: Grand/ Futa

Chapter 4:
Mad Mama's Mammaries

Minamoto no Raikou

By: JellalRaven

Ritsuka's POV

"Go-Ou Shourai – Tenmoukaikai!"

Raikou called the name of her Noble Phantasm. The mobs we were facing stood no chance as the AOE NP demolished them, turning them all to ash.

"Yeay Raikou!" I cheered. "With this we are done with today's farming!"

"I'm so happy when you praise me, Master!" Raikou chuckled. She pulled me in for a hug and almost choked me as she pressed my head into her cleavage. Her tits truly were massive. No to mention her skin tight bodysuit that didn't leave much to the imagination. The huge mammaries were way bigger than mine, they must have been around I-cup. But even when I could not breath I refused to complain. I just enjoyed the moment.

After a few weeks of being a futanari I had managed to learn some self control, so it took more than a tight hug from Raikou for me to get a boner. I was still a bit iffy about telling others about my conditions, so I had decided to hide the fact that I had a futanari cock under my skirt.

"We should head back!" Francis Drake said with a yawn. "I'd like to get a drink before the day is over!"

"I wouldn't mind that either." I muttered, face still stuck in Raikou's cleavage.

"Now, now Master!" Raikou scolded me. "No drinking for you, we would want that insect to get her hands on you and poison you!"

"Aren't I a grown woman…" I mumbled, but Raikou refused to listen.

"Don't worry, dear! I'll cook you a nice hot meal when we get back to Chaldea!" Raikou finally let go of me and I massaged my neck.

She always makes a mess in the kitchen. I better stop her or EMIYA and Boudica will have to clean up the kitchen after her again!

"Ehh, Raikou. Instead of cooking me a meal… Ehh…"

I had no idea what to say…

"Yes dear?"

It just slipped out…

"Could you come to my room?"

Now I've done it!

"You want me to come to your room?" She asked confused.

"Yeah! I wonder if you could give me a massage instead of making me a meal." I doubled down on the idea. Not a good move!

"O-of course!" Raikou yelled. "As your mother I must make sure you are in good health! Giving you a massage is the least I can do!"

"Thank you, Raikou." I said, giving her a bright smile.

Ohhh, now I've done it!

Some time later in my room...

I was used to have sex with Mash, Artoria and Mordred. They were a great help to keep my urges in check. I had of course thought about having sex with Raikou, in fact I had thoughts about having sex with most of my servants. But I had messed up when I asked Raikou for a massage. She was a Berserker, she was more likely to break my spine than give me a proper massage. Not to mention that the stimulation from a massage most likely would give me an erection. My magical panties that Merlin gave me helped a lot, but even they had limits.

"What should I do? It's not like I can call it off, Raikou would cry if I suddenly called it off!" I walked back and forth in my room, trying to come up with a plan. But as I was lost in thought Raikou came bursting into my room.

"Mommy is here!" She declared as she stormed in. "And I brought a bunch of stuff! Oils, sponges a massage bed! I even brought some snacks!"

"Raikou, I-" I noticed what she was wearing. Her summer outfit.

Her massive tits were covered by a purple bikini that only managed to cover up her nipples, but only barely. The string bikini was tied tight around her bouncing tits, and I could see her nipples already were erect under the bikini top. Her bikini bottom didn't leave much to the imagination either. The bikini bottom covered her pussy, but again, only barely. I could even see how her clit was erect as well, under the bikini. I stared at the "motherly" Berserker as she put down a basket of items and skipped up to me with a lewd smile on her face.

"Is it a bit much?" She asked, swaying her body slightly, making her tits sway as well.

"N-no…" I lied. "It's… Perfect…" How was I supposed to act. I loved the Servants' summer versions, and Raikou's was just too good. The only problem was that my dick started to get hard.

"Then please undress, Master!" Raikou told me.

"Ehh?"

"You must be naked for me to give you an oil massage!"

"Right… Oil massage…"

Ohh Mama, how am I supposed to survive this?

I turned away from Raikou and unbuttoned my uniform. Raikou told me to lay face down on the massage bed she had brought. I took off everything but my panties. She would not actually tell me to strip them as well!? Right!?

"Ohh, Master. I need you to take off your panties as well." Raikou told casual.

My cheeks turned red, I was blushing like crazy.

"Do I really…"

"YES!" She snapped. "I need to massage your butt as well!"

"What?" I asked, more scared than confused.

"Massaging the whole body is important to relieve all the stress! It will also make for great skinship between mother and daughter!"

What else did I expect from a Berserker that saw herself as my mother, she truly was mad. But I couldn't just tell her no, it was too late for that. And I had used up all my Command Seals during a recent event so ordering her to back down was pointless. I just had to roll with it. But then I got an idea.

"Raikou, could you get my hairband? I left it in the bathroom."

"Of course! Just get comfortable!" She then headed to the bathroom, happily humming to herself.

I quickly pulled off my panties and jumped on the massage bed, tucking in my balls and penis under my stomach so that Raikou could not see them. I then just had to pray that she did not ask me to turn around.

"Found it!" Raikou cheered as she came back. She handed me the hair band and I put it on. "I see you have already made yourself comfortable, my dear!" She sounded ecstatic. "I'll just begin then!"

I could not really see what she did, but I could hear her putting oil on something, her hands maybe?

"I'm going to put some oil on your back now!" She told me.

"Mmm!" I answered.

The warm oil suddenly was poured on my back. I shivered a bit as Raikou spread the oil all over my back and even my butt. When she touched my big butt my cock started to twitch under my stomach. Raikou's warm hands caressed and massaged my soft ass cheeks. I let a slight moan out, trying to pass it as a yawn. But then I felt her finger slide against my butthole.

"Ihhh!" I squealed.

"Sorry." Raikou purred.

"I-it's fine!" I muttered, my cock twitched like crazy and I could feel precum leak from the tip.

Raikou the massaged my back, her strong hands finding all the right spots to relieve my stress. I sighed as she was actually quite good at giving massages. I relaxed and let her hands and fingers touch my back and butt as much as she wanted. Sometimes she would find an especially sensitive spot and I would let out a quiet moan.

Then she climbed on top of the bed. My heart raced as Raikou pressed her giant tits against my back and began to move them up and down my back. I also felt her erect nipples against my back, meaning that she had removed her bikini top. The fat udders felt great against my stiff back, the heavy yet soft sensation of two tits pressed against me made my cock go wild. My dick started to pulsate and got fully erect as Raikou massaged my back with her cow tits. We both panted like bitches in heat. Feeling Raikou's body against mine made me happy. I could not deny that I wanted this, but if it kept up I would expose my penis and the fact that I was a futanari.

I was about to ask Raikou to stop, as I was about to cum, but she stopped rubbing her tits against my back herself. She got back up from the massage bed and giggled to herself.

"Fufufu, I think it is time for the front now."

My heart skipped a beat. The worst possible scenario had come to pass.

"I'm fine with just getting a back rub." I said, hoping Raikou wouldn't question me.

"Nonsens!" Raikou said. "As a mother I must look to your back and front when relieving your stress!"

"Raikou, I'm fine. Really!"

"Now, now, Master! Mother knows best! Come on turn on your back!"

She grabbed me and I was about to protest but was too late, in the blink of an eye Raikou had already turned me over, exposing my front and my raging cock.

"Ehh?"

At first Raikou just looked at the cock. Her initial dumbfounded expression quickly changed to an expression of shock and she screamed in surprise.

"EHHHHH!?" Her tits bounced wildly as she was shaking from the revelation. "My Ritsuka, my daughter is… A boy? But… Breasts… But p-penis… But… But…"

Raikou got all flustered and I knew I had to act quickly to calm her down. I got down from the massage bed and hugged the tall woman. She quieted down and seemed surprised that I was hugging her.

"Ara?" She said.

"Raikou, I… I am a futanari!" I confessed.

I explained what had happened. How Merlin had turned me into a futanari. How Mash, Artoria and Mordred had become my partners and how we all the time had sex to fulfill each other's sexual desires. Raikou seemed to understand as once I was done with the explanation, she just smiled and hugged me.

"I don't care if my dear child has a penis and vagina!" She said. "A mother will always accept her child!"

"Raikou…" I was shocked over how well she took it. But it made me happy that she took it so well.

"And as your mother I need to make sure you don't go around and fuck just any girl when you have a hard peepee!"

"Ehh?"

Raikou grabbed my hard cock that had been pressing against her bikini covered pussy this whole time. I blushed as Raikou rubbed my cock with her oily hand, her soft hand against my rugged girth felt amazing.

"As your mother, I must see to your every need!" She purred.

Raikou leaned in and kissed me. Her soft lips gently pressed against mine as she forced her tongue inside my mouth, still rubbing my cock. We both moaned as we made out, our tongues battling for control. But battling a Berserker was useless, she overpowered me and I let her tongue dominate mine. We both gasped for air when Raikou ended the kiss. I had instinctively grabbed on to her tits during the kiss, which seemed to please Raikou.

"You like mommy's tits, huh?" She gently patted my head.

"I… I love mommy's tits…" I confessed.

Raikou's face lit up and her lips formed a bright smile. She pulled me to the bed and gestured for me to get up on it. I got up on the bed, still all oiled up from the massage and layed down on my back. My cock was standing straight up and was leaking big droplets of precum.

With a lewd smile on her face, Raikou took her cow tits and pressed them against my cock, sandwiching it between the two udders.

"Ohhhh!" I moaned, thinking I would cum at once.

Raikou's ample bust was beyond amazing. Having her soft and oiled up boobs pressed against my rigid cock was a dream come true. She moved her erotic tits slowly at first, teasing my cock by gently rubbing it's pulsating head. She moved her tits up and down, side to side, her supple titty flesh wrapped around my cock, as if it was stuck in an onahole. When Raikou picked up the pace she also took the tip of my cock in her mouth. I would have cummed there and then, but I had enough control to hold back my climax. Raikou let her smooth lips suck and caress my cockhead, sucking all the precum from my rigid shaft.

The thing about Raikou's blow/ titty fuck was that she didn't hold back. Her lips pressed firmly against my cockhead as she vacuum sucked all the precum from my dick, while her huge cow tits pressed against my thick member. We both moaned in ecstasy as she kept going. The worst thing was that she was too good. Her soft, oily tits felt too good against my cock. Not to mention how she was vacuum sucking the tip of my cock, sipping all the precum into her mouth and down her throat.

We locked eyes and I could see how happy she was. Her eyes sparkled as she serviced my cock. Then I felt it…

"Raikou… Mom, I… Ohhhh!"

My balls clenched and my shaft shoot out a full load of my fresh hot semen. Raikou was unprepared for the amount and only managed to swallow a little before she let go of the dick and let the rest of the seed splatter all over her chest. She chuckled happily as she smacked her lips, licking up all the cum that had landed in her face. She let her tongue play with the cum as she ate it, tasting it properly before swallowing it.

"My precious child's semen… My mouth might get pregnant from this…"

"Raikou… That was amazing!"

I had titty fucked Mash before, but her tits had nothing on Raikou's. Especially when Raikou's were oiled up and she sucked the tip of my cock. I had to add that to the list of things I wanted to do with Mash and the other girls. Maybe if I came enough on Artoria's and Mordred's chests their tits would grow a few sizes?

Speaking of tits. My tits had begun to lactate and so had Raikou's. Small streams of thick white milk were leaking from her tits and mine did the same. The cum that had stained her face and chest had been sucked in by her pores. I think her lips had gotten a bit thicker, but beyond that she was normal.

"Why are you lactating!?" She screamed. "Are you pregnant? Who fucked you!? Was it Cu? Hector? Astolfo? Was it that stuck up Gilgamesh? Trying to be a golden boy when my Kintoki already is the best golden boy!"

Raikou's tits bounced and leaked more milk as she was ranting.

"No! I'm not pregnant!" I quickly told her. "It's just an effect from the potion that Merlin gave me!"

"So Merlin got you pregnant!?" She squealed. "That pervert! Taking advantage of you like that!"

"No that's not it!" I tried to reason with her, but Madness Enchantment EX was a pain to deal with.

I got up to hug her but when I put my arms around her I could feel how my dick was pressed against her stomach. She got quiet and looked me in the eyes, I saw pure madness in her big eyes. For a second I was scared. I could feel how Raikou grabbed my dick and rubbed it as she ripped off her bikini bottom. She exposed her hairy pussy to me and I gasped as she pushed me on my back and got on top of me.

"As your mother, I will always aid your sexual urges! That is my role as your mother!" She guided my cock to the entrance of her damp snatch and paused. My heart was beating like a drum. Raikou's pussy was already wet and was dripping her love juices on my erect member. With a swift motion she sat down on my cock, letting my hefty girth enter her wet vagian.

"Ohhh!" I moaned as I could feel her pussy-folds rub against my thick shaft while she let my dick enter her inch by inch. Raikou's snatch was unlike any other I had fucked. Raikou's pussy was looser, but her folds were more defined and felt great against my cock. Raikou could take my full length inside her without a problem. Her hairy pussy greedily swallowed all my ten inches and I gasped for air as her pussy lightly squeezed my dick when it was fully inserted inside her.

"As your mother I must please your big cock!" She moaned.

The motherly Berserker then begun to move her hips up and down, rocking both me and the bed. Our tits bounced and swayed, leaking warm milk on our bodies as we fucked. My thick cock rubbed against her slippery and warm vulva, making us both moan as Raikou's ass moved up and down on my dick.

"Rai… Raikou!" I moaned, unable to tell her to stop fucking me.

"No! Mommy! Call me mommy! I am your mother!" She scold me, slamming her ass down faster and harder on my raging futa cock.

"Yees! Yees! Mommy! Mommy! I want mommy to fuck me silly! I want mommy to mess up my thick cock with her loose pussy!"

"Don't tell your mother her pussy is loose!" Raikou scolded me.

Her pussy suddenly tighten around my cock and I could feel how my tip was knocking on Raikou's cervix. The tight hole that was the entrance to raikou's womb felt just like Mash's asshole. Tight and firm. I chuckled for myself as my cock kissed her cervix again and again, never fully penetrating it.

"Mommy! My cock feels sooo good!"

"Mommy feels good too, honey! Mommy feels so good when she fucks you!"

"My cock loves your hairy pussy!"

"And my hair pussy loves your long cock!"

Her pussy got tighter and tighter as we continued fucking. I was pretty sure her cunt was going to squeeze my dick to mush if we went on long enough. Her wild hip movements made it impossible for me to control myself. I matched her hip movements, but that was all I could do. Our hips made slapping and smacking sounds as we smashed into each other. Raikou was dripping her love nectar on my cock as I was leaking precum in her slippery snatch.

"I wanna… I wanna drink… Mommy!"

Raikou understood what I wanted and pulled me up into a hug. As I had Raikou sitting on my dick, all I could do was hump her while she slammed her ass down on my thick dick. But I could finally drink from her tits.

I had always wanted to drink breast milk straight from the teat, but as I was the only one of the girls that had lactating tits, I could not do it as I pleased. I could pull and stretch my own tit to suck on my nipple, but that hurt and I could never produce a steady stream of milk. Now that Raikou was lactating as well I made sure to capitalize on the opportunity.

I latched on to one of her erect nipples and sucked as hard as I could. A thick stream of warm milk filled my mouth and I gulped it down as the greedy child I was. As I was drinking her milk I also made sure to squeeze her tit as well.

"Yees!" Raikou moaned, her lewd voice making my heart race even faster. "Suck mama's titty! Drink all of mama's warm milk! It does you good!" She cooed.

As I was drinking her milk and humping her slutty body, Raikou gently patted my head like I was a baby. She truly was like a mother. And I loved it. Fucking the other girls was amazing, but fucking Raikou made me feel naughty and at ease at the same time.

"Ohh! Mommy's gonna cum, dear!" Raikou gasped, saliva dripping from her thick lips. "My child's thick cock is going to make this slutty mama cum like a bitch in heat!"

I didn't say a thing, I just kept drinking. Sucking on her nipple as if my life depended on it. Raikou put her arms around me and I could feel how her perverted pussy clenched around my cock.

"I'm such a perverted mother, cumming from having my child's cock inside me! I should feel ashamed, but I can't help but to love this big cock! And it makes me feel so good! CUMMING!"

I finally felt how my balls clenched as well, ready to expel my seed inside my mommy.

"Mommy! I'm cumming inside my mommy!"

My shaft flinched wildly as my spunk erupted from my cock and inside Raikou's damp pussy. The white goo flooded her snatch as we both held on to each other and moaned. I would have been afraid that she would get pregnant from such a large creampie, but merlin had reassured me many times that Servants could not get pregnant. So I happily emptied my balls inside Raikou's cum-starved cunt.

Raikou pressed her thick lips against mine as the last of my load filled her up. Her big lips dominated mine as we held each other close. My oozing seed was dripping out of her incestuous cunt as we laid down on the bed.

"You cannot tell anyone about this!" I told Raikou before I latched on to her nipple again.

"Ritsuka my dear…" She rubbed my head as I drank her warm milk. I really loved it when she mothered me. "You shouldn't hide who you are. Everyone at Chaldea loves and respects you, I know they will accept you, penis and all!"

She really does sound like a mother…

I stayed quiet and kept drinking her milk.

"Fufufufu. Drink all you need, my sweet child. Mama will stay with you always!" Raikou kept patting my head as I drank her sweet milk. The big breasted Berserker hummed a lullaby for me and I soon drifted off to sleep in her arms.

That night I ended up sleeping like a baby.

BB's POV

"Well girls, what do you think? Pretty interesting huh?"

I smirked as the faces they made were priceless. I had picked the perfect time to show them the truth of our dear Master. Even if it meant showing them my secret surveillance room.

"As… As her wife I must accept her every part! You villain! Trying to deter me from my beloved with such a erotic display. This maiden's love for her is still as strong as ever!" The fox maiden didn't seem to be too disturbed by the erotic scene she had just witnessed.

"For once I agree with the blue Caster… Umu! I for one love this revelation! To think my precious Praetor have the luxury to feel the pleasures of a woman and a man! Her very body is a work of art!" The tyrant emperor was as bombastic as ever.

I was happy that the two reacted as they did. My plan ad worked. If they could fall for senpai even if she had a massive cock, then why would not the rest of the girls fall for her too? I could now enact the second part of my plan.

"Would you two like to make love to your beloved Master?" I asked the two servants, knowing fully well what their answer would be.

JellalRavan:

And the mama with the big monster melons joins the harem! I am having a blast writing this series. I aim to introduce a few girls (and some guys) with every chapter from now on. If you would like to see anything in particular then leave a review! I am always listening to suggestions.

I also aim to have stuff like pregnant servants and more hardcore stuff in future chapters, I just want to introduce most of the girls first!

Look forward to the next chapter! I hear some Extra speCCCial girls are joining Ritsuka's harem. Something about a fox and an Umu?
