Issei listens, but eventually his hands start to wander.

After Issei calmed down, Rias invited him to sit down so she could explain. Naturally, Issei sat down next to her as opposed to the couch opposite, but his perverted plans were shelved for the time being as he listened to Rias explain about the Three Faction, the Peerage System, and Sacred Gears. Or at least, he tried to pay attention. It was a little difficult when his eyes kept getting drawn to Rias's bountiful chest, which bounced at even the slightest shift in her posture.

"...and that's probably why she tried to kill you. Because her superiors detected a Sacred Gear inside you and wanted to eliminate a threat. Though I have to wonder...what kind of Gear would cause them to kill you while you have yet to unlock it?"

As Rias began to theorize on possible Sacred Gears he might have, Issei finally lost the battle with his libido as his eyes locked onto Rias's magnificent chest. He could ask her any remaining questions later, it was time for some fun!

"...but all this is just speculation. To find out for su-Eep!" Rias was cut off as Issei picked her up and shifted her onto his lap before his hands swiftly headed upwards, quickly removing her shoulder cape and ribbon before starting to undo the buttons of her shirt. "Uh, what are you doing?"

Issei didn't answer at first, focusing on pulling her now unbuttoned shirt open and sliding her black lace bra up to free her tits. Rias moaned as Issei's hands began to play with her sensitive breasts, and almost jumped out of her seat as Issei finally spoke directly into her ear, "I'm doing what I came here to do the other day. Lose my virginity with the hottest girl in Kuoh."

"W-what...?" Rias felt her face heat up even as she squirmed in the grip of Issei's ministrations. She gasped as she shifted and suddenly felt something big and hard that had formed a tent in his pants. Meanwhile, one of Issei's hands reluctantly released it's hold on her boob and began to travel south. "You mean...you intend to have sex with me?"

Issei chuckled and continued to speak, "Yep. I mean, you said that you help your Peerage with their goals and dreams right?" Rias nodded as Issei's hand had reached her thigh, where it slipped under her skirt and began to stroke her inner thigh. Issei smiled as his hand brushed her panties and felt the damp fabric, "My goal and dream is to become a Harem King, and if I'm not good enough in bed I'll never be able to keep any of my girls happy. So wouldn't it be normal for you to help me practice by having sex with me on a regular basis?"

"I-yes. Yes it is." Rias shivered, Issei's words and actions were quickly turning her on. Her hips began to move, grinding her tight ass against Issei's rock hard erection, even as Issei's lower hand pulled her panties aside as it began to stroke her wet snatch. "But my parents wouldn't approve of me losing my virginity before marriage...and do we have to do it now? I still need to tell you abo-"

And then two of Issei's fingers plunged inside her core, drawing a loud moan from the crimson haired devil. The pair of fingers wasted no time as they began to stroke and tease her insides, while the thumb began to lazily circle her clit. "All you're doing is helping your new Pawn, it's normal for anyone to understand and accept that without objection. Everything we do will just be considered a normal method for us to bond. And we can talk later. I've been waiting too long for this."

"Yes...yes, you're right..." Rias's breaths grew shorter and shorter, even as her gasps and moans filled the room. "And I-ah suppose the rest can wait...very well. I'd tell you to-ah, enjoy yourself, but it seems you already are."

"You're not wrong." Rias could feel Issei's hot breath on her ear, her new Pawn revealing in the control he had over her. "Can you imagine what the school would think if they saw us? To see the school idol so shamelessly moaning at the hands of a vile pervert? The girls would be horrified, while the boys, on the other hand, would be willing to sell their souls to be in my place."

Rias couldn't help but picture it, her and Issei on a stage as he toyed with her body, the students of Kuoh watching. The girls watching in horror and outrage, the boys stewing in their jealousy even as they jacked off to the sight. The voyeuristic thought pushed her over the edge, and Rias came hard, her inner walls clamping around Issei's fingers as her juices covered his hand and soaked his pants.

Rias panted as she sat there, coming down from her orgasmic high. Issei wasn't finished though, as he turned her face towards him and captured her lips in a passionate kiss. Issei's tongue invaded her surprised mouth, seemingly trying to taste every part of it.

Rias moaned into the kiss as she recovered, her tongue dancing with Issei's until the need for air separated them. Rias pulled away with a flushed face, a strand of saliva connecting their lips, "Th-that was my first kiss..."

"There's going to be a lot of firsts for both of us tonight." Issei smiled impishly at her as he brought up the hand her had been using to finger her and began to clean it of her liquids. "Mmmm...Delicious. I want more."

Issei gently picked Rias up and set her off his lap before leaning in and kissing her once more. This time he allowed her to be the one to explore his mouth. Pulling free, to Rias's displeasure, Issei lowered his head and captured one of her pink nipples in his mouth. Rias's moans once more filled the air as Issei lavished his attention on her breasts, alternating between each one with his mouth, while his hand entertained whichever one he wasn't suckling.

Rias knew Issei was a pervert, but even she never thought that he'd use her tendency to dote on her Peerage like this. She thought some teasing, flaunting her nude body, and the occasionally reward grope would keep him happy. Instead Issei went straight for the grand prize. Although, a gleeful part of her noted, at least this would deny Riser any chance at taking her virginity himself.

After spending a few minutes working her tits, Issei reluctantly gave each one a final kiss before moving south. Gently spreading her legs, Issei licked his lips before giving Rias's pussy a slow lick. "Ooohh..." Rias moaned, "D-do that again please."

"With pleasure."

Issei gave Rias a few more licks, each one drawing a moan loader than the previous one. And then Issei dove in, his tongue digging in and worming it's way into her depths. Rias gasped and her eyes rolled to the back of her head. Her fingers dug into the couch as her legs clamped around Issei's head. "Dooooo-don-don't stoooOPPPP!"

Issei smiled as he ate his redheaded King out. The beautiful Rias Gremory, writhing with pleasure through his actions. He felt like the king of the world, and he thanked whatever god or demon made these earrings.

It didn't take too long to bring Rias to another orgasm, and Issei decided that he'd had enough foreplay. Issei wiped his face with his sleeve as he stood up, admiring Rias's flushed face as she smiled up at him. Her gaze shifted downwards as he began to undo his pants, her eyes widening as she finally saw Issei's cock. Issei kicked away his pants as he aligned himself. "You ready, Rias?"

Rias stared down at were the tip of Issei's dick was pressed against her lower lips. Biting her lip and bracing herself, she answered, "Yes. Do it."

Issei took a deep breath, and thrust. He briefly felt a barrier, but it broke quickly, and then he was sheathed inside Rias's hot, wet pussy.

"Ahhhhhhhhhhhh!" Both of them all but screamed at the sensations. Issei do to the utterly amazing sensations his cock was feeling as Rias clamped down on him, and Rias do to the brief pain of her lost maidenhood and the surprisingly pleasant sensation of being filled.

They sat there for a moment, adjusting to the new sensations, before Rias spoke, "That...It feels..."

"Incredible..." Issei supplied.

Rias nodded, "Yeah...Can you...move?"

Issei responded by slowly pulling back till his tip was the only thing in, and then thrust back in, drawing another set of moans from the twosome. This time, he didn't stop. He continued to thrust, picking up speed as he fell into frenzy of sorts. Rias's arms wrapped around Issei's neck, pulling him down and locking lips with him.

When the finally parted do to lack of oxygen, Issei's eyes were drawn to Rias big tits, which were bouncing up and down with every thrust. Grabbing one with his hand, Issei once more began to suck on her nipple. "Ah! My breasts...!" Rias gasped, "....Feels so good!"

The two devils lost themselves in the haze of pleasure, Issei pounding away at Rias's eager body. However, all good things must end, and Issei felt his end coming quite quickly.

"H-hey! I'm going to cum-can I-?" Issei stammered out as he felt his hold about to give.

"Inside! Inside is fine! Just, just don't stop!" Rias panted, her own release about to give as well.

And with one final thrust, two voices cried out in unison: "I'M CUMMING!"

Rias's walls clamped down like a vice, practically milking Issei's erupting cock. Issei stilled as his cock finished pumping his baby batter into his King. The reality of what he had just done finally hitting him. He'd done it...he was no longer a virgin!

Issei wasn't left with much time to think before a flash of light **** him to close his eyes. He felt Rias push him back onto something soft, and his eyes opened to see not the Occult Research Club room they'd been in, but a bedroom. He didn't have much time to examine it as his gaze locked onto Rias, who was stripping out of her remaining, disheveled clothes.

"Well," Rias smiled at him as she bent over to slide her skirt and panties down her legs, "School ends soon, and I'd rather not have the rest of the Peerage walk in on us. And I doubt you're content with just that one round. So I moved us to my bedroom."

Issei smirked as he started stripping out of his own remaining clothes, "Works for me."

As Rias sauntered forward, Issei paused as an idea popped into his head, "Hey Rias? You said earlier that as a Pawn I can do something to increase my strength and speed, right?"

Rias's eyes widened before a lustful grin appeared, "Issei, I give you permission to promote to Queen."

Over an hour later, Rias collapsed on top of Issei, resting her head on his chest as they rested from their final explosive climax. "That...was unbelievable." Issei finally said, "I could die right now and be perfectly happy."

"No dying." Rias curtly responded, "As your King, I will not accept that. Besides, I...you can't train with me and become a Harem King if you die now."

"Don't worry, I fully plan on realizing my dream. And perhaps one day you won't just be my King and training partner, but an member of my harem." Rias smiled and rolled her eyes, her new Pawn was quite ambitious, wasn't he? "But right now I'm exhausted." Issei chuckled before yawning. Rias hesitated before kissing Issei on the cheek and then snuggling against him, "We'll see Issei, we'll see. Goodnight."

"Goodnight."
