"Sure, but why so—"
Rias didn't let Keiji finish his speech as she was already kissing him passionately, rubbing her buxom body all over him and arousing the pheromones, making them shoot out of his skin and flood the place in a perfume of lewdness.
"—Horny?" Keiji finished off.
Rias panted after the kiss. Her hand went straight for his cock and began jerking the fat flaccid length to greater heights, her hand already being able to feel the blood pulsing and expanding it into the monster that it was. "Let me just suck it!" she begged out.
Keiji instead gripped Rias by her hands and planted her down against the bed, looking down on her and his cock admiring her form as it expanded while Keiji resisted the urge to ravish Rias senseless. The struggle was harder as, thanks to the thickness of his length, it was already rubbing against her clit.
"Before I even attempt to fuck you, and believe me I do, I want you to tell me why," Keiji ordered, staring deep into his leader's eyes.
Rias blushed at his dominant display. She clearly couldn't fight against him. "Well, I'm a bit jealous that you've been fucking those other girls but not me!! she spurted out but Keiji wasn't fully convinced, making Rias look away. "And I'm contracted to marry a person I don't like, so I figured I'd let you take my virginity."
"Fuck it. I'm down. If this guy is that bad you're willing to give away your virginity, then I'll gladly take it for you. Besides... I've definitely gotten excited over this body once before," Keiji breathed out, caressing her curves and making her smile.
At that moment, the immersion was broken when a red seal glowed, prompting Rias to sigh at who it was. Keiji wasn't expecting much but his cock grew thicker the moment he saw who came out. A woman of unearthly beauty with back-length silver hair that features a long braid on each side with small blue bows at the ends, while the rest is let down which ends in twin braids and silver eyes. Her figure, though a bit supressed from the maid attire, was definitely proving to match or potentially surpass Rias' own.
"Is this what you've decided to do, Lady Rias?" the woman asked.
Rias sat up, her eyes still distracted by the throbbing hard on that was pressed near her. "I don't want to marry Riser. It's my choice on who I give my virginity to, Grayfia."
"Who is she, exactly?" Keiji asked.
Grayfia put a hand up. "I shall explain to him, Lady Rias. Greetings, Red Dragon Emperor, Keiji. I'm the maid of the House of Gremory, Grayfia. Rias has talked much about you," she said, making Rias blush. "But onto your point, Lady Rias, it is not my intention to stop you from going with this action," she said.
"Huh?!" both devils got out.
The red lips curved into a sensual smile that brought forth arousal in both of them. "As a matter of fact, I've decided that I would like to join in on the sex. Would that be okay... Lady Rias... Red Dragon Emperor..."
Keiji moved away from Rias, showing the heavy organ that instantly sent hearts into the eyes of Rias and Grayfia effortlessly stripped out of her garments, pouncing on Keiji and already sending shivers in his body at the way she expertly grasped the shaft and began massaging it with her fingers.
"It's so thick and smells so strong. I made the right choice!" Grayfia said before hogging it into her mouth, her ass wiggling and turning all parties on.
"That's not fair, Grayfia! I should get to have a go first!" Rias complained. But seeing as the maid wasn't budging, she went to go caress Keiji's body while making out with him. 'I can do this much. I'll pleasure him better than you!'
Grayfia's mouth was rapidly sucking, her tongue coiling and making sure to get the most out of the length. It took some time but Grayfia was able to take it all down, and being so close to his crotch allowed the pheromones to go further into her and turn her more. 'I need more!' she mindlessly thought as she began to gyrate her hips and molest his balls.
'These girls are so hot! I feel like I'm melting with the two of them!' Keiji thought, his cock expanding a bit in Grayfia's. Seeing her fat ass shake like that, Keiji reached out and began to finger her pussy. 'It's soft!' he thought, before chuckling a bit as Grayfia was also using her hands to help Keiji spear his fingers into her pussy.
Rias plucked her lips from Keiji but felt like he still wasn't paying attention to her. 'There's only one thing to do now!' she thought, pushing Grayfia off of his cock and hogging it in her mouth. She had a sort of pouty look as she bobbed her head up and down, passionate and eager as Keiji felt himself grip her hair and fuck her face harder.
Grayfia groaned at being exiled off his cock but she smirked. "Wow, you are being such a slut, Rias. It's very pleasing," she commented. "I think I'll have to teach you a lesson," Grayfia added, bending down and licking against Rias' clit.
'Even Grayfia! I'm gonna cum lose my mind!' Rias thought, which she was very close to as Grayfia stimulated her pussy enough to get her to orgasm and a flood of fuck fluids came right down her mouth but was too much for her virgin mouth to handle and so it started to spill.
Seeing the cum spill from behind Grayfia, she used her strength to flip Rias the other way, took her off Keiji's dick, and began to kiss her, allowing the cum to enter her mouth. Keiji's dick curved even harder at that as Grayfia finally pulled her mouth off Rias. "You shouldn't waste the seed of such a specimen, Rias. It's disrespectful," she lewdly stated.
Rias nodded with dainty eyes. "Yes... Grayfia..."
"Who do I go for?" Keiji muttered as he looked to find that Grayfia had dragged Rias down with her and essentially made a pussy sandwich.
Grayfia hugged Rias tightly in her place, preventing her from moving. "Rias, I'll be kind enough to be a bottom for this. Now, Red Dragon Emperor, who would you like to fuck first? Doesn't our wet cunts just excite your appetite?"
"My name is Keiji!" he roared out to Grayfia, shoving the whole length in at once. Her moan was loud and pleasant but Keiji didn't stop. As soon as he hit that spot, he get moving his hips into Grayfia until she would orgasm like crazy.
Feeling bold from what Grayfia did to her, this time it was Rias who initiated the kiss as she began to distract Grayfia and help Keiji double team her as the dragon devil continued to rock his body into her madly.
The feeling of her pussy was so intoxicating to Keiji that he couldn't even hold it for long before releasing inside of Grayfia, the maid's head fulling back.
And with her out, Rias found herself squealing lewdly and fast as Keiji pulled on her and let his cock in and out of her pussy, opening it up bit by bit. "I can't stop, Rias! I just want to have sex with you!" he told her.
Rias turned back to face Keiji with a smile on his face, bursting with love. "T-that's fine! I'm more than happy if you breed me silly! I'm just glad I got to do it with you!" Rias commented with a smile that quickly turned lewd.
Entwining her hair in his fingers, Keiji lifted her head up and pulled her in for a kiss. Having her body curve for him definitely set off Keiji as his cock was already twitching and finally began filling her up, making Rias contort in delight as exhaustion kicked in soon after.
Keiji pulled out, his cock still cumming. He jerked it off a couple of times and it coated the girls behinds.
"Hey, Asia, you're taking too long," Ilulu commented, until she looked to see Keiji having just finished with Rias and someone she didn't know.
Her boobs began bouncing up and down as she waved her hands. "Hey, that's unfair! Why are people cutting in line?!"

An orange circle arose with burning flames. Inside of it was a man with a burgundy blazer and matching trousers. His teeth were grinding against each other in anger. "Rias... I hear that some other low blood has claimed you! Do you wish to bring shame to both our clans?!" he grunted out.
'What's his issue?' Keiji thought, just ignoring the commotion.
Rias slammed her hands on the table. "That doesn't matter, Riser! I get to decide on what I do with my body. Consider this a rejection!"
"You!" Riser pointed to Keiji, who just rolled his eyes. "You must have been the one who ruined this, didn't you?! Riser will not show mercy to you."
Keiji had a look that said give me a break. "Don't look at me like I'm too blame. If Rias went to me, it just means you weren't to her tastes. Now stop bothering me."
Riser's flames continued to swell to a point that Keiji sighed, thinking he was going to have to fight. Only for the atmosphere to become chilly, which came from Grayfia. "Riser, might I remind you that you are in the human realm. You should not casually flaunt your power so casually. If you have any issues, it can be solved with a Rating Game."
Riser smirked. "If the Strongest Queen asks for it, then even Riser must back down from it," he admitted. He then turned his dark blue eyes to Rias. "My fiancé, is this truly all you have as your Peerage?"
"And what of it?"
The Phenex heir laughed. "You don't even amount to a full set, while I do," he remarked, the sigil of the Phenex appearing as a variety of girls popped up. All of them varying but all of them are definitely fuckable.
"If that's all, then I wouldn't get too confident. I can wipe them off the floor by myself if I wanted to," Keiji remarked with a confident grin.
Riser clicked his teeth. "Be quiet, filthy commoner! I'll have to put you in your place, where you belong! Mira, take care of him!"
The blue-haired girl stepped forward with her bo staff to fight but Keiji's aura exploded, sending her back and making her tremble in both awe, arousal and fear. "H-he's too strong for me," she admitted, shamefully; the other girls were also affected in the same way.
"Pathetic!" he admonished. Riser then pointed to Rias. "I'll give you ten days to train up as best as you can. Then I'll crush you, and even more to you... commoner!"

"You sure work fast," Keiji pointed out to Rias as he and the other members of the Occult Research Club stood in front of a giant mansion that looked to be a whole condominium, complete with lush green space and beautiful symmetrical separations.
Rias smiled. "Of course. It's for the best. We have ten days to show Riser why he's going to lose!"
"I can't wait to get started!" Ilulu shouted, appearing from out of nowhere. Koneko had an irked look as she watched bouncing boobs from someone around the same height of her.
Keiji exhaled then grinned. "Well, let's get started, then!"
