Yes, and they discuss the future a bit!

"Okay, sure," Issei smiled as he stood. "We can go out tomorrow. Maybe I can show you some of the Japanese cuisine Irina mentioned to you. Maybe we can teach you an appreciation for our dishes."

"It's a date then. And even if we can't go for having children right away, we can always try to plan for it, right?" Xenovia asked. "We can pick up condoms for you to practice with..."

Issei was glad he hadn't been taking another drink at the moment, that might have resulted in another spit take. "Yeesh, you're really set on this, aren't you?" he asked.

"Condoms are unnecessary regardless," Rias noted with a smirk. "Master Issei wished to ensure no unintentional pregnancy long ago. He could fuck us for years without protection, and we'd never get knocked up, unless he wanted to do so."

Xenovia's eyes brightened at that notion. "Truly? Your Sex Genie powers can influence pregnancy?" she inquired.

"Of course they can," Rias snorted. "Pregnancy is very, very strongly associated with sex, given it's often the end goal of it, or an accidental result, etc. It's one of the biggest reasons that Devil leadership is so interested in where the Lamp goes."

"Because Devils struggle with having kids, right?" Issei questioned, and Rias nodded.

"...so it can go the opposite way, and ensure pregnancy instead of preventing it?" Xenovia questioned, and Rias beamed.

"See, you catch on quick. That alone is a huge potential game changer in the balance of power between the Factions. The possibilities are endless, really. Ensuring conception, making the pregnancy less difficult on the body, ensuring no birth defects, even in cases of ****, speeding up the fetus's development, making labor pleasurable instead of painful, preventing any complications, ensuring twins or triplets if desired, just about anything you could think of to make family planning more convenient, really," Rias explained, placing a hand on Xenovia's shoulder. "So worry not, my new Knight, even if Master wants to wait a little while, when the time comes, we'll all certainly bear him at least a few children each..."

Issei's head spun as he processed all of those implications as Xenovia looked absolutely enraptured at the realization that all the downsides to pregnancy could easily be dealt with, and that it could come so easily, even with her being a Devil. How had the conversation gone from him saying he wanted to wait a while before fatherhood, to his Genie and potential newest harem recruit conspiring to give him enough descendants to form his own faction?

Ddraig himself put in his two Yen, his tone tinged with faint amusement. "...I am currently unsure whether to congratulate, or pity you, Partner. Or both."

Issei ignored that comment for the most part. "Let's not get too hasty, everyone," Issei told them before Xenovia could fantasize too deeply. "Again, this is still in the far future, and while I agree that there's no harm in thinking things out a little early, there's also still the politics to consider."

"Ugh, politics..." Rias groused. "Kill them with fire..."

"...oh, that's true. I suppose the idea of a Devil baby boom would be cause for alarm for both the Church and the Fallen," Xenovia realized.

"Which, again, is probably why Sirzechs has yet to ask me to start using Rias's powers to help Devil couples who are trying for conception do so..." Issei nodded. "He and the other Satans no doubt want to get on the same page with Michael and Azazel before doing anything drastic. We'll probably have to figure out ways to aid the other two factions with Rias's power to an almost equal extent, before we can chance doing something like that if we don't want the Church and Fallen getting spooked enough to make an alliance against Devils to prevent us from getting too numerous or something like that."

"Exactly. So we can probably expect to be called to a meeting between the leaders of the Factions regarding this matter. Not to mention the Kokabiel incident," Rias mused.

After that talk, and a few other, more casual topics were discussed, the party wrapped up, and they all headed home, or in the case of Xenovia and other members of the residence, slept at the club.
