The Poll was pretty clear that you guys wanted a DXD story so here we go!

Quickly for new readers I write Futanari stories so I hope you like it, also I haven't seen all of DXD so if some people are out of character cut me a small break? I decided to start off the series with something I knew I would like.

For story purposes we'll say this starts a little while before the start of the series.

Rias' POV.

"I don't remember this being in here…" I said skimming over a book.

"What are you reading?" Akeno asked walking over.

"I found this book down in the basement of the club manor." I said "I didn't recognize it so I thought I'd scan it over to make sure it's nothing too bad."

I stopped on one page "Do you recognize this spell?" I asked my friend.

"No I can't say I really do." She blinked "Are you sure this book is serious, maybe it's just a pretend for fun book that got tossed in with the rest by mistake."

"I'm positive it's real." I told her "Look at these symbols I've seen them before but some of the stuff her, look the way these pictures are…what would you say it is?"

"Well…they do look a little like sex positions." Akeno smirked "Maybe this is a naughty book…I like it."

"Calm down." I pushed her head away from me "Get your mind out of the gutter."

I turned the page again and noticed that this time the text was glowing.

"Do you see this?" I asked showing the Queen the book.

"See what, that's a blank page." She commented.

Why…can I see text?

"Ummm Rias?" Akeno said with a bit of worry.

I stood up and started concentrating some magic.

"Are you…casting a spell from that book?" she said "I don't think this is a great idea."

"It…feels like I'm supposed to do this." I said as I started reciting a spell.

"I…fine." Akeno shrugged.

I stood up as the magic poured out of me.

"Rias?" Akeno yelled "I'm getting a weird family.

As I reached the end of the spell a massive magic circle appeared on the floor and I was at the center of it.

"HAAAA!" I gasped as I was suddenly bathed in a light.

What…is this feeling?! It…it…It feels incredible!

I felt a heat building up in my body, my clothes started to feel unbearably tight and then suddenly ripped off, my already big breasts bounced slightly and they felt a bit heavier, I groaned as my wings suddenly popped up and I was sure I felt them grow larger.

"OHHHHH!" I moaned as I felt a soreness near my crotch.

"HAAH!" I looked down and saw the skin and flesh in that area wiggling and bulging up.

"Ah…ah…AHHH!" I screamed as I saw a large penis erupt out from above my vagina and a pair of testicles dropped down.

Suddenly the light faded and I dropped to the ground.

"Rias!" Akeno ran over to me "Are you alright?"

"I…I…I feel…"

I looked at her as I stood up "I feel so alive!"

"W-What happened to you." She gasped.

My wings were larger and more leathery, my butt had a bit more bounce to it, my breasts had suddenly puffed up to be larger than Akeno and most notably I had a throbbing foot long penis sticking out of my crotch.

"I feel incredible." I moaned before Akeno "So…what do you think?"

"You…wow." She gulped.

"I understand this now." I said picking up the fallen book "This was a sex book, a sex demon's book to be more precise. It's awakened something deep down inside me."

"You…have a penis." She pointed out.

"A fun little addition don't you think." I smirked "I'm a true Futanari Succubus…or since I have a penis perhaps I'm really an Incubus?"

I looked at Akeno, her large breasts, her glorious curves…she would be prefect.

"Rias?" she noticed my peering eyes "Something wrong?"

"I need pleasure to calm myself." I said "You'll help me will you not?"

"Hmph." She scoffed "I had a feeling you'd say that."

She reached forward and gave my balls a squeeze with the iron grip and even tingled her hands a bit with lightning.

"Let's see what the new you can do." She smirked "Take me for a wild ride."

"MHMMH!" I shot forward and pulled her into a rough kiss, shoving my tongue down the devil's throat.

"OHHMMM!" she moaned back as our tongues swirled and our breasts mashed together in what was a beautiful sexual sight.

As the kiss intensified Akeno suddenly broke it and dropped to her knees where she began to stroke my length.

"Ohh that's perfect." I groaned as I reached up to squeeze my supple bosom.

"I can't believe you actually have this." Akeno said moving her hands.

"Don't stop with those lightning charged hands you sexy beast." I said "Once you give me a reason I'm taking you to feed my pleasure drives."

Akeno stopped her hand job and then licked my junk before taking it into her mouth. I let off a grunt of satisfaction as Akeno's glorious mouth sucked my cock. I was pinching my nipples to further pump up my pleasure. As a succubus I needed to feed on pleasure it was a basic instinct but it also caused me to have a high ceiling of need.

"GURGLE GURK!" Akeno bobbed her head as she reached down to unbutton her top and unhook her bra, letting her heavy breasts swing free.

Look at those delectable melons, I can't wait to suck on those.

I started thrusting my hips slightly and forcing my cock deeper down her throat. My foot long injector was all the way down her throat and I was loving it, Akeno seemed to be struggling to take it all at once but it felt so good I wasn't going to let her spit me out.

"GAGG!" Akeno gasped and gurgled as she struggled to hold my big dick in her throat clearly she was struggling to breath but now I felt a powerful sensation bubbling up in my balls.

"Yes, I feel it!" I moaned "TAKE IT!"

"GUAGGG!" Akeno gagged as I filled her throat and mouth with my first ever load of cum.

A good amount of white spunk spewed out of my penis and covered Akeno in a sheet of cum.

"Mmmm." I licked her cheek to taste myself "You perfect."

"Rias!" she moaned as I licked her all over with my tongue, cleaning the semen off her face before I trailed down and teased her tummy with my tongue and then found my way to her slit where I quickly put my tongue into her.

"HAAA!" she squirmed as I grabbed her milky thighs and shoved my head into her crotch.

My goal was not to give Akeno an orgasm, I just wanted to get her nice, wet and ready to take my cock into her perfect pussy.

"RIAS!" Akeno moaned as she dug her fingers into her big tits "Your tongue is incredible!"

I felt more of her juices leaking out of her hole as my tongue probed her walls and when she was nice and ripe I leaned up and started using my cock to tease her clit.

"Are you ready to feel the best sensation ever?" I asked.

"Please…I want you." She groaned "Fuck me so hard."

"I can't wait to feed on you." I said licking my lips "URRGH!"

I grunted as I slowly pushed into Akeno's tight pussy, I reached out and grabbed one of her beautiful titties. I quickly began rocking my hips, sliding in and out of her, gradually getting more of my cock into her pussy.

"Oh…oh yes!" Akeno moaned "That feels so good!"

"YES!" I groaned "Take my cock you slut, give me your energy!"

I grinded my body against my Queen, I fondled her melons and felt my ass clapping as I drew closer and closer to blowing my load and achieving the desired satisfaction I so desired.

"AKENO!" I yelled as I felt my chest flopping around "I…I'm about to…"

"YESSS!" she moaned as her walls shifted "I'M CUMMING RIAS!"

I felt energy flowing into me as I feed off the desire and sexual power of the lovely Akeno, my body felt perfect and I once again felt that new feeling in my balls.

"GAAAHHH OHHH FUCKKKK!" I screeched as I filled her full of cum.

I pulled out of Akeno and fell back.

"Rias?" she spoke up "Are you alright."

"Phew…I feel a lot calmer now." I panted "Being a succubus though…I could grow used to it."

"I think you will too." She smirked before kissing me again.

I'll have to learn to curb my desires a bit…but the future looks great.
