Highschool HxH

[A succubus's blasts Rias with an aphrodisiac that finally pushes Issei's to lose his virginity and begin to bang his other lovers]

"Hah, hah, hah, I-Issei."
"R-Rias!? What are you- "
"Isn't it obvious... we are engaged now, so we its time to consummate our relationship, right?"
Rias was hovering over him. His buxom, beautiful crimson-haired fiancée was completely nude and had a manic look in her eyes. She had pinned his arms down to prevent him from running. Issei was trying to figure out what had happened to her. It had been a few hours since they had dealt with a stray devil that had been hiding in the red-light district area of Kuoh Town. It had been a succubus who was draining the men in the area of their life force. Both his peerage and hers work to stop it but in the middle. They had found her with a new victim. She was wearing a pure black negligee that one could see her big oppai behind it
"Oh my, it seems that some more boys have come around here, why not dump the girls and have time with a real women."
"Gulp."
She hopped and twirled around showing off her assets. Issei enjoyed it and the other girls took noticed and gave him a look of annoyance. Both Koneko and Akeno spoke up.
"Thinking of perverted things Issei-senpai."
"To think you had thoughts of cheating when you are surrounded by us."
"N-No, I already have plenty of big boobs around me already."
For a moment his face was a lewd smirk, but he knew he needed to stay alert against this foe. Though he was nearly caught off guard.
"Issei, Look out!"
"Huh?!"
Rias pushed Issei out of the way of a blast that was cleary meant for he.
"Rias?!"
"Oh, I meant to hit you with that."
"You Bitch."
The succubus gave a smile and wink.
"But I am doing you a favor, I could feel the tension between all of you."
"What did you-"
"You'll see soon enough."
For some reason, afterward she just gave up, even promised to give back some of the energy she stole from the men she recently drained, thought the earlier guys were far too gone to do something.
Though in Issei and the other's mind they were more concerned about Rias, since she had collapsed from the blast. Thankfully she was not injured seriously or affected initially, but she kept eyeing Issei and sizing him up, it felt like she was ogling his muscles underneath his shirt and looking at his crotch. Issei didn't know how to feel, granted he felt it wasn't okay to just comment since he was really bad at ogling girls and talking about perverse things like sucking on tits and feeling them up. They went home after that and Issei was just getting out of the bath, enjoying it with the church trio and as he headed into his room.
"Hee Hee, caught you."
"R-Rias?!"
Rias turned Issei around and captured his lips, she forced his mouth open and proceeded to ravage his mouth and tongue. Issei was caught off guard as he just let her go to town on him, even dancing her tongue against hia, not wanting to be on the defensive, he attempted to grab at her chest, but then he realized something, she had come up behind him not wearing any clothes.
"Pah, R-Rias, why were you walking around the house naked. Think of what-"
"But if my clothes were in the way, we couldn't have sex, so I just stripped it off before I came to visit."
"W-Wait, What."

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

And now he was on his bed with Rias like a lioness ready to take her prey, she blew into his ear as she proceeded to keep kissing him, she even went for his neck and was leaving marks on it. She sat straight up and looked directly at him. From his view she was a statuesque stunner, her red hair flowing all the way down her back, the most perfect set of boobs Issei would ever lay eyes on, perfectly soft and bouncy in how they move, and curves that also accentuated her bottom and already child bearing hips. Her skin was completely smooth but that was when Issei had noticed a rather noticeable Tattoo had formed on her chest, it appeared to be heart shaped and was also glowing, if he remembered correctly this was where she got hit. Could her sudden urges have something to do with that.

"R-Rias why don't we calm down here for a bit and-"
"No! I am sick and tired of all this coy teasing and cuddling. Didn't you promise to take my virginity almost a year ago. Where is that Issei!"
Rias had puffed out her cheeks as she looked down at him with half lidded eyes. He had promised that to her, and he was always adamant about his desires, but he kind of struggled to act on them, wanting to ensure a perfect mood and time to do it, he attempted to open his mouth but Rias proceeded to giggle to herself.
"But its okay, I know that Issei is still a virgin himself, and as the older person here, its my job to be the perfect first time."
She proceeded to slide down the bed towards his lower body and proceeded to use her teeth to pull his boxer's down, tugging at it with her might until her goal sprung free.

THWAP

"Oh my."
Issei's cock proceeded to smack Rias as she freed it from its prison. She had seen him nude various times prior to this but he was always flaccid or barely hard. Now before her was massive giga cock,

maybe it got bigger after his body was recreated she didn't know and didn't care.

"S-Sorry about-"
"What is their to be sorry about, what should be happening is you apologizing for not using this yet."
"I-I thought you would've been terrified by it, it has been... a lot bigger recently."
"It seems you still lack confidence, don't worry let me help you build the confidence to be the harem king."
Rias licked her lips as she stared at it and began jerk it off with her hand, she started out slow and sensual to get a look at his reactions, he twisted and turned and his face was a mixture of his usual lewd look when he was being a pervert and his face scrunched in pleasure. She soon picked up the pace as she wanted to see the different ways he reacted. She slided back to his face and began to face his nipples.
"My you seem so tense, don't worry I promise to help you feel less tense."
"Gah."
She began to swirl her tongue around one of his nipples, drawing more moans and groans out of her boyfriend. He felt himself melting at the affection, and the feeling of her body against him. He should be trying to talk her out of this, she clearly was not in the right mind for this... but the pleasure was too much for him now.
"See, just relax and enjoy yourself. You want to know what I think you would enjoy the most?"
"W-What would that be."
She removed her hands and did the thing that was a staple of Issei's naughtiest dreams as she proceed to his dick between her bosom.
"Getting to use my boob-pussy for tit fuck. The boobs of your favorite woman."
Issei felt his legs turn to jelly at Rias's soft flesh pressing into his dick. She began to massage it by moving her boobs up and down. Taking a lick at his head, the feeling of her boobs and mouth across her dick was enough to drive him crazy, he also began to buck his hips at the pleasure he was feeling.
"Easy there, your senpai promises to give you release, but let's hold off for a little longer, that way you have the best ejaculation."
He wanted to cum, badly, he wanted to sully her face and breasts with his dick milk, but as her pawn, he should listen to her, so he attempted to hold himself back as she picked up.
"Good boy, nice to know you don't just mindlessly hump until you just cum, you also desire something greater and-"
"Ghhhhhrk."
She proceeded to smash her boobs even closer, creating a tight funnel as Rias went full throttle.
"Ahhhhhh, this is-"
"You enjoying it, I can feel it pulsing, violently demanding release, as your King I will allow it, cum all over my face, let my red and your white cum mix together beautifully."
"Ahhhhhh."
He didn't need another second as he came hard. He was spraying like a volcano, one that shot hot white semen, Rias opened her mouth up to try and catch any of it to taste, the rest stained her front body white, after a over a minute, Issei's ejaculation finally subsided."
"Hah, Hah, Hah... woah!"
As Issei regained his senses, he took a look at Rias, body bukkaked by his cum, her boobs having a pool of the stuff right around it and his dick and her body have splotches all across. This was something he did and to his darling fiancée and he enjoyed the sight of it, if he was still allowed masturbation he would use it... though he imagined it wouldn't happen. Rias proceeded to clean his dick and slurp up the cum in her valley of tit flesh.
"Hee hee, this stuff is actually kind of tasty, maybe I should have you nude from now on when I want some of this stuff in my tea."
"P-Please... don't do something like."
"You sully this princess with your jizz and get embarrassed at being nude in public. Maybe your not as perverted as you claim to be."
Rias said those words in a slow, sultry tone of voice, as she freed Issei's dick from her boobs, it did get a little flaccid.
"Oh my, it seems someone has spent too much time masturbating, maybe you don't have much... but that doesn't matter."
Rias pushed her boobs right up to Issei's face, Rias had always let him sleep in her tits but their was something hungry for it. As she moved her body up and down, her womanhood resting on his dick
"Come on, get that cock nice and hard again and let my womb enjoy your extra sticky, rich cum."
"Hmmmmmmmph!!!!!!!"
Issei was losing his mind to pleasure, Rias was also starting to put off a scent that was going right to his dick too, was that also an effect of what she got hit by. At this point it seems that at this point the only thing that could calm her down was the ensure she was pleased. So if he wanted to help his fiancee, might as well go with the flow.
"Go. Fight on. You can do it."
As Rias continued to rub her body, she felt his dick growing back to full mast, and a giddy smile went to her face, which was even gidder when Issei overpowered her to push her onto the bed.
"Ahhhh, finally, you want to take control of it."
"Hah, Hah."
"Yes, those eyes want to breed, so please, conquer my pussy for now and forever."
Issei lined up his dick with her pussy, it was leaking like crazy, only even more when Issei began to take charge, and with a single thrust.
"Ahhhhhhhh!!!!"
Issei could feel her pussy coil around him, wanting to squeeze him completely, he almost came, but he was a gentlemen, he wanted to ensure she enjoyed herself, but he did notice something, the heart symbol that was on her chest disappeared. And with that Rias seemingly lost the pink glow behind their eyes.
"R-Rias, are you back to normal?"
"I-Issei?... Issei?!"
And she had no memory about what had happened.
"I-I can explain, you got hit by some weird succubus power and then you cornered me and started to act all seductive and horny, and I just thought that it would make sense to I... I'll just-"
"Don't"
"Huh."
Rias looked at him with blush and darted her eyes to the side as she and Issei were finally going to do it.
"I-I don't mind for us to continue. Just promise me one thing."
"That being?"
She whispered the next part into his ears.
"That you hug me really tightly."
With his sweet fiancée back to normal, Issei decided to start off a bit slowly since this wasn't horny out of her mind Rias. Even at the slower pace, Rias felt herself melting into his embrace. She was going
to have a discussion with that succubus about this little trick she did, but at the same time she was happy to finally to be connected to Issei.
"Hah, Hah, Issei, mmmmmm."
She proceeded to latch her lips around his, deep kissing with him as he slowly began to build up speed with his thrusts, going from slow to an average pace. Even if this was their first time, he somehow

had found all of her weak points, he broke the kiss to start suckling on one of nipples like a baby.

"Y-You really are crazy for these, that you would leave my lips lonely. Oh well, I think I'll just explore your body too."
She felt his muscles up, he had gone from rather average to having some well defined muscles. She took in how handsome. She knew that he would have to divide his attention with the others when they

figure out they finally committed the deed. But tonight."

Push.
"Eh?"
"I'm done with this dainty stuff, I want to be in control.".
Rias pushed Issei's back right into the bed as she now started to bounce herself on his member. Issei also took the time to also fondle the glorious boobs that were flailing about like crazy at the

princess's descent into lewdness.

"Your boobs truly are the best, there may be bigger but there is just something to these."
"And they are yours to do whatever you want with, just like how this cock will forever be mine!"
She could feel it getting hotter and harder inside of her, was it close to ejaculation? She should probably try to pull out now... she should, but she wasn't.
"R-Rias, I am about-"
"Its all right, you can spray all of that cum directly into my womb, you can feel it, my never touched has met your cock desperate to breed, it has lost and desires to be conquered-"
Plap, Plap, Plap.
"I want my first orgasm to be compounded by you pounding me into submission and cumming directly inside-"
Plap, Plap, Plap.
"So forget all those worrisome thoughts and cum directly into my womb."
All reason was lost as Issei put both of his hands on Rias's hips and started to force her down onto his cock, penetrating her womb. Rias' tongue began to hang out of her mouth, she could feel her brain

melting with each thrust, if she wasn't careful she may end up corrupted by the pleasure. But it didn't seem like a bad thing.

"Ah, Ah, Ah, Ah."
"Yes Issei, keeping pounding me like that, claim me like you did that night atop the griffin, I am yours to do what ever."
"Ghhhrkkk, cumming."
"Ahhhhhhhh!!!"
As he continued to piston his dick into her, a stream of cum began to flow right inside of her. All of her eggs, defenseless to his seed as it traveled from dick to womb. Rias threw her head back as it reached her womb and she felt euphoria, it felt like it was never going to end as he kept pushing his hips forward to ensure that he got her filled to the brim.
"Yes, more and more of your warm stuff inside of me."
After a bit, his climax subsided as Rias proceeded to nuzzle herself closer to his face as she enjoyed the afterglow.
"Hah, hah, hah, that was-"
"Wish we did it sooner than we did."
"Y-yeah. I would have enjoyed it doing it a lot... maybe even have the other girls-"
"I mean... they don't have to join yet."
"Huh."
Rias gave him an aside glance as she riggled her butt to get his dick a bit harder.
"I know it is selfish of me to ask, but I want you all to myself for a bit. Do you not want that."
"U-Uhhhhhh."
A spurt of blood came from his nose at the idea.
"No, I wouldn't mind doing whatever you asked."
She gave him a lustful smile.
"Good, now shall we continue."
