A/n: This came from an rp that I'm doing with futanari DxD females.

Plot:

Y/n is the best friend of Rias Gremory, and knows about her being a devil. However, while Y/n appears to be a normal kid, he has one big secret. He's a futanari slut, just like his mother, and wishes to be taken by them.

However, what he doesn't know yet is that the Gremory Family women are futanaris, and  that Venelana, Rias's mother, has developed a crush for Y/n, and with a bit of Rias's help, and Y/n's own mother, Venlana plans to turn him into a sex toy for her and the other Futas of the Gremory clan.

---------------------------------------------------

No one's POV

We see the Gremory family mansion, with Venelana sitting in her room, wearing a very slutty outfit, which is showing her giant Futa cock.

Venelana: He should be here soon~ *lick lips*

The doors then open, and we see Y/n walking into the room, shocked by what he's seeing.

Y/n: H-Hi Miss Gremory...

Venelana: Ahh~. Fufu~. Hello N/n~

Y/n: *gulps* Why are you... um... well... naked...?

Venelana: *stroking her cock* Fufufu~. Well since you have a small cock, you wouldn't understand but you have such a massive and strong cock like mine~, any kind of clothing Is rather uncomfortable so I prefer to be naked and besides~. I know how much you and your slutty mother love staring at our massive Futa dicks~.

Y/n: W-Wow... it's... so huge... What is it's size...?

Venelana: Fufu~. Are you curious you cute little femboy~?

Y/n: *gulps* Well... a little bit... yeah...

Venelana: *giggles* Well, since you really want to know~ I'm 34 long and 18 thick~.

Y/n: W-Wow... S-So big... C-Can I touch it...?

Venelana: Of course~. You can lick it and suck on it too~.

Y/n: I-I'll just start with touching it...

Venelana: Fufu~. Mmm very well~

Y/n then slowly walks towards Venelana's cock, and at he slowly touches it, Venelana starts playing with her boobs, and starts moaning.

Y/n: Wow... It's so... big.

Venelana: Mmhmm~. You like it don't you~?

Y/n, realizing what's going to happen, starts smiling a bit more lewdly.

Y/n: Yeah~

Venelana: Fufu~. You're good with your hands N/n~

Y/n: Thank you Miss Gremory~

Y/n then starts moving his hand a bit faster, making Venelana moan.

Venelana: Oh yes~! Just like that~

Y/n: Do you think you can... bless me with your cum~?

Venelana: Fufufu~. Perhaps~ but you'll have to work for it~. Start licking you sissy~.

Y/n: Okay~

Y/n then starts licking some of the sweat off of Venelana's cock, making her moan a bit more in pleasure.

Venelana: Ahh~. Y-Yeah~. Just like That~! Mmm that feels good~. Keep licking boy~.

Y/n: Of course Miss Gremory~ I want that cum of yours so badly~

Venelana: Then be a good little sissy and start sucking~. Then I'll cover you in my superior Futa cum~.

Y/n then smiles in pure joy, thinking of how he'll feel being covered in a Futanari's cum, and starts slowly putting his mouth onto her cock.

Y/n: *muffled* Is this good, Lady Venelana~?

Venelana: Mmm~! Fuck that feels good baby~! Suck mommy's cock more~.

Y/n then starts deepthroating Venelana's cock, making her moan loudly in pleasure.

Venelana: Fuck~! Yes! Just like That you stupid Little whore~! Keel sucking on my dick! Make your mistress feel good~!

Y/n: *muffled* Of course Miss Gre- no. Of course Mistress! Bless me with your superior cum~! Make me your new "wife"!

Venelana: *scoffs* You take After Your Mother!

Venelana then grabs Y/n's head, and starts cumming deep down into Y/n's throat.

Venelana: MMAAAAAHHHH~~~!! FUCK~!

Y/n keeps drinking all of the cum that's going down his throat, and after a few minutes of Venelana cumming, takes his mouth off of her cock.

Y/n: Mistress~! Bless my body with this gift~!

Venelana: *starts relaxing a bit* Ahhh~. You want more~?

Y/n: *panting* Yes Mistress~

Venelana: Then where do you want it~?

Y/n: Right on my face~ Let me feel it all over my lewd body~

Venelana: Hmm~. Then how about you spread your ass~?

Y/n then smirks and stands up, showing his ass to Venelana.

Y/n: Like this mistress~?

Venelana: Just like That~. Ready~?

Y/n: Yes~ Pound my asshole full of your superior cum~ Make me more than your "wife".... MAKE ME YOUR BREEDING BITCH~!!!

Venelana: Good Boy~

Venelana then starts pounding Y/n doggy style, causing both of them to moan in pure bliss.

Y/n: Your cock~ It's so big~! *moans* Fuck~!

Venelana: Mmm~! So tight~! Ah fuck~! It feels so good~!

After a few minutes of doggy style, Y/n looks towards Venelana with a lewd smile on his face

Y/n: Mistress... Can I suck your tits while you fuck me~?

Venelana: Fine~

Y/n: Thank you mistress~!

As Venelana turns Y/n around, so he canc suck on her tits, Venelana starts fucking him faster.

Venelana: Ahh~! Ahh~!! That feels so good~! Mmm~! Ahhh~!

Y/n: *moans*

Y/n: HARDER MISTRESS! FUCK ME SO HARD THAT WHEN YOU CUM, YOU MAKE ME LOOK PREGNANT WITH YOUR BABY!

Venelana: Hehe~! Gladly~!

Venelana then starts picking up the pace, and as it happens, her dick starts twitching inside of Y/n, indicating that she's about to cum.

Y/n: *moans* I CAN FEEL YOU TWITCHING! RELEASE IT ALL INSIDE ME!

Venelana: AHHH~! TAKE IT ALL YOU STUPID FILTHY SLUT!

Venelana then makes one final thrust into Y/n's lewd body, and as he screams out in joy, his tiny little dick starts cumming, with it hitting Venelana's body.

Y/n: *gasps* I'm so sorry mistress! I didn't mean to hit you with my inferior cum!

Venelana: Fufufu~. Don't worry~. It still feels nice~.

Y/n: *panting* Did you know that you took my virginity, Mistress~? Oka-san's going to be so happy for me~

Venelana: Fufu~. I'm glad to hear that~.

Y/n: *panting* So~ What's next~?

Venelana simply smirks and pulls out of Y/n's ass, allowing her cum to slowly drip out of him. She then lays down on the bed, after tearing off all of her clothes, and taking off her wedding ring, tossing it in the garbage bin that's nearby.

Venelana: Now you bounce on your Futa mommy's cock~

Y/n: Of course mistress~!

Y/n then slowly gets himself ready, and immediately lowers himself onto Venelana's cock, making him jerk his head back in pleasure

Y/n: So Good~ *Small Ahegao face* You dick's hitting my deepest parts~! I wish I had another cock I could suck~

Venelana: Ahh~! You're such a tight little sissy~. And look at that worthless little dick bounce~!

Y/n: Thank you mistress~ I'm glad I was born, and able to take your futa cock~!

Venelana: That's a Good Boy~. You're nothing more than a sex toy for the Gremory Clan and a cumdump for the Futas and big cock guys at Kouh! Got it~?

Y/n: Mistress... I don't want to be fucked by guys~ After all... after taking your rod... ONLY FUTA COCK WILL PLEASE MY CO- no. PLEASE MY LITTLE BOY CLIT~!! SO PLEASE MISTRESS! *Image Below* LET ME TAKE NOTHING BUT ALL OF THE FUTA COCKS IN KUOH~!

Venelana: Hmm~. Well we have to keep the other guys happy so how about you watch your favorite girl get fucked by them and you will watch like a good little cuck~, okay~? If you agree to it, you can be a Futa exclusive sissy, okay~?

Y/n: Of course mistress~! I'd be delighted to do that to Murayama~!

Venelana: Good Boy! Now bounce faster as you think about Murayama forgetting about you and falling in love with cocks that you'll never be able to defeat~!

Y/n then starts bouncing faster, thinking about how the two will be married not to each other, but to cocks.

Y/n: Oh Murayama~ I know that we'll become the best sluts of Kuoh~! I just know we will~! You'll fall in love with big boy cocks, while I take big Futa cocks~!

Venelana: Mmm~. Good boy~. Keep bouncing~

Y/n then starts bouncing faster, and starts making Venelana's dick twitch.

Y/n: GIVE IT TO ME AGAIN MISTRESS~! TURN ME INTO A SISSY, BORN ONLY TO TAKE FUTA CUM AND COCK!

Venelana then starts cumming inside of him after he said that, and as Y/n moans out in pleasure, he falls onto Venelana's boobs, making her hug him.

Y/n: So much~ so much cum in my belly~ If I was a girl, I'd definitely be pregnant right now~

Venelana: Indeed~. You make a good cumdump~.

Y/n: Thank you mistress~ I'm glad I was able to please you~

Venelana: You did good~. Now get some sleep~. You'll be needing to stroke your pathetic little dick when you watch your favorite girl break~

Y/n: Mistress, when it does happen~ When the men break her... Can you get another futa to plow me, just so Murayama can see what a slut I truly am for Futa cock~?

Venelana: Of course~

Y/n: Thank you~ I can't for that day... It can't come any sooner~

As Y/n falls down, and starts stroking his dick, with cum leaking out of his ass, Venelana smirks and as she walks out, says one thing.

Venelana: You're Welcome~

As Venelana leaves, Rias comes walking up.

Rias: So? Did you do it?

Venelana: I did~ He's not more than a sex toy now~

Rias: Do you think me and Isami will get to fuck him?

Venelana: I know you two will~ But not today~ He's a bit worn out from the pounding I gave him~

Rias: Well, you do have a huge bitch breaker! No wonder daddy left you after learning how many femboys and females you cheated on him with~

One-Shot End!
