High School DxD: The Red Dragon Sex Emperor

Rias proceeded to gently kiss him, sitting on his dick she decided to just enjoy this feeling of being full before they went at full throttle.
"A-Are you sure about this," Issei said looking at Rias, as she lay on the bed.

Her hands bound together as her eyes darted around at her pussy, glistening with anticipation and leaking love juice onto the bed.

"W-W-W-Well, I just wanted to let you have full control of this, so being tied up makes me nothing more than a cock sleeve."

Whenever they had sex, Rias did sometimes put in some control, whether she was on top or when Issei was pounding her. However, a part of her wanted this, too, to lose the control she had as a princess and be nothing more than an outlet for Issei's lust.

"Okay, but if things start to feel uncomfortable, just… kick your legs into- "

"Shut the fuck up and get over here right now, you have a girl begging for your dick, so come on!"

Rias shuffled to spread her legs apart to entice him. Issei got onto the bed and he proceeded to grip her hips. Rias felt her body tingle in excitement as he felt his cock brush against her pussy. Her spine shivered as she couldn't even press herself back.

She needed it so fucking badly.

"Kyaaaaaa, how much longer will you attempt to embarrass me, please? Plow your thick cock inside of my shameless pussy, I don't care what happens to me, just make me feel as good as fuck!"

Rias seductively begging for his dick was all that Issei needed, like a part of him wanted to see his proud girlfriend beg for him like that.

Now, he soon was inside of her.

"Ahhhhhhhhhh!"

Rias didn't know why this felt different, his dick was still the same size, the same filling thickness she was well aware of. However, maybe it was the fact that she couldn't look back at him as her face was pressed into the bed by Issei's weight. The bed that they had been fucking in for hours had their scents mixed together, and his scent drove her crazy.

"R-Rias… you're so… tight."

"Ahhhhh, but you feel so good, getting fucked while you shove my face into the bed full of your scent… I can't help but coil around your amazing dick! Harder, faster, right now I am not the heiress of the Gremory Clan, just a girl desperate for her master's dick!"

Rias Gremory's desperate plea for rougher treatment sent Issei into overdrive, gripping her butt as he pressed his cock even deeper. He proceeded to breathe into her ear which to her was completely unfair, but the pleasure she was feeling was insane, nothing she had ever felt before, and upon feeling his dick enter her womb..

The crimson big-breasted girl came so hard.

"Ahhhhhhh, cumming, cumming! Fuuuck I'm cumming, cumming, cummmmmmmmmmmmmmmmmming."

"Guh!"

Rias's climax caused her pussy to tight harder around his dick. Her eyes slowly went into her head as Issei treated her like an onahole.

'Oooooh, this isn't good, every thrust feels like he is breaking me down, turning me into the servant and him the lord, his hands are like electric, and I can't do anything! I've allowed Issei to turn me into a cock Sleeve… and I want him to do it more often.' The lustful lewd succubus thought as she came.

"Orrrahhhhh!"

Issei Hyoudou found his reasoning slowly leaving him, the respect and devotion turning more into lust and desperation, and being the oppai man, He turned her around to start sucking on her tit flesh.

"Nooooo, not my breast, if you suck on them, I'll completely sucummmmmmmbb!!!"

"Mmmmmmm."

Issei's right hand groped and played with her left breast while his mouth suckled on her right tit, taking licks around it. Rias's mind slowly clouded over by lustful desires as Issei pounded her pussy and played with her tits.

"I-Issei, ahhhhh!! You're so rough, you don't have to be so rough, these breasts will always be around for you to do with whatever you want."

"I know that! These tits have belonged to me for as long as I owned your virginity."

Issei bringing up her virginity loss, made her heart flutter. She could feel it as he roughly loved her tits as he throbbed inside of her.

"Hrgh, Cumming."

"YES!! Fill me up, let my womb drink up all of your cum!"

Issei didn't need to be told that as he came hard, drowning her pussy and womb with a maelstrom of cum, Rias let out a scream of carnal pleasure as her lover filled her up once more, but it wasn't enough, it was never going to be enough, and she had a way to make sure tonight she was going to get all that she wanted.

"Hee, Hee, so full, but I can feel it, still so hard, you dragon bastard. How about I do some of the work now."

Rias looked back at him, her eyes begging to keep on fucking, and who was he to ignore her.

"Mmmmmmmm, mmmmmm"

KISS, SMOOCH, PAH

Rias sat atop him, hands still tied up behind her as she leaned down for a kiss, as their tongues danced against each other as she opted for a shallower thrust her ass bouncing against his crotch.

"Ooooh, Issei's kisses are so lewd, we used to have such gentle cuddling kisses, I want to kiss like this forever!"

"R-Rias, keep bouncing."

Rias soon ended the kiss as she proceeded to bounce atop him, Issei taking in the statuesque stunner of a girlfriend he had, her enormous breasts bouncing as she pleasured herself and him with her cowgirl ups and downs.

Her beautiful crimson hair, sweat dolloping specific points, they hadn't been in the bath for a while, it felt like their skin was sticking together like they were one person connected with one another. Issei absolutely didn't want this to end, the feeling of her tight devilish pussy around his cock, her tits on his face it was absolute bliss.

"Ahhhh, Issssseiiii, keep up this pace, I need this!"

The once refined and regal princess was replaced by any girl desperate to quell the heat she felt as Issei kept fucking, piercing her womb as she slowly converted her into a cock sleeve, and unbeknownst to Issei, Rias was prepping a spell, if there was ever a good chance for pregnancy, this was it.

"Hurry, cum inside me, fill me, let my womb have another fill of your delicious creampie, so fulfilling."

"Guh, yes, I going to fill your womb again!"

Issei didn't know why but he really wanted it now more than ever to cum, to fill her, he gripped her hips as he pulled her down on top of him.

Rias threw her head back as she felt him about to climax, to unleash his seed and once it was done, her trap would be set.

"Cumming!"

The two lovers yelled out as a flood of cum shot up into Rias's womb, the feeling of absolute nirvana as each shot flowed out of Issei's cock and her pussy coiling around his dick.

However, as he continued to cum, Issei felt his cock for some reason getting even bigger inside of her as he kept pumping inside of her, and soon moving became quite difficult.

"W-What."

"Hee hee, caught you."

Rias proceeded to undo the ties, very clearly, she practiced escaping as she snuggled up to Issei.

"Rias… what did you- "

"Oh, don't worry, it's nothing dangerous, I just used a spell to make your cock bump me, it'll be a bit before it shrinks and you can remove it, but until then, you'll cum as your cock enjoys the snugness of my horny pussy."

Rias twirled her asscheeks as she kissed his forehead.

"So why not just enjoy each other's company, as you proceed to finally breed a child inside of me wouldn't you say."

Issei really couldn't believe it, but it seemed that she was right about the knotting. As she cupped his head, he simply decided to kiss her, the two enjoying the slower-paced sex as things quieted down.

"Issei, thank you… and I... I love youuu ♥️ I love youu so much ♥️" Rias said hugging Issei tightly with a look of satisfaction lingering in her blue eyes.

A few minutes passed. The residual heat from the intense sex had subsided, and Issei wiped his sweat-drenched body and changed into light clothes, but Rias remained completely naked.

She said she couldn't sleep unless she was completely naked, so maybe she didn't want to leave.

"Hey, Rias. Isn't it about time you told me? Why did you resort to such desperate measures?"

Rias, still naked, lowered her gaze but then raised her face as if making a decision.

"You're right. I should tell you. But before that..." Rias said as she stood up and faced the window.

"I know you're there! Come out, Grayfia!!" With those words, the same red magic circle from earlier appeared on the floor, glowing vertically.

From it emerged a big busty woman in a maid outfit with silver hair.

"Sigh... did you really go to such lengths just to call off the engagement, my lady?"

The woman, called Grayfia, sighed deeply saying those words.
