Yes, and Akeno wants to join!

"Well then... What say the three of us move on to the real celebration?" Issei asked Rias and Asia, the former beaming, the latter blushing, but also smiling a bit at the thought of sex with Issei right now.

"Of course, Master~!" Rias chirped. "Shall I go ahead and pull the privacy curtain?" she added, pointing to a corner of the club room that had the bed in it, and an enchanted curtain that was magically sound proofed.

"Actually, before that... room for one more?" Akeno asked, approaching the trio. Rias grinned as Asia and Issei froze. Issei turned towards Akeno, the implications running through his mind.

"...are you suggesting what I think you are?" he asked after a moment, his heart pounding, and hoping she said yes.

"If you're thinking that I am asking to join your harem... yes, yes I am," Akeno giggled. "Though I do have some requests I would like to lay out..." she added, a bit of a devious glint in her eyes.

Issei shivered. "We can... negotiate the terms," he finally said after a moment.

"No!" Koneko wailed. "He got to Akeno too! I should have known it was only a matter of time until she was corrupted and tempted by this Sex Genie nonsense when she used Dress Break on Yubelluna!" she wept.

"...let's not kid ourselves. She was always a perv, Issei just is an interesting catch for her, more so with Rias involved," Kiba chuckled.

Issei also chuckled, before he blinked, before looking at Akeno in a legit double take. "Wait, you used Dress Break on Yubelluna?" he asked her, stunned. "How do you even know the spell, I never taught it to you!"

"Issei, Issei, Issei," Akeno replied playfully, wagging her finger. "Aren't we forgetting just who taight you the basic ideas on how to create the spell in the first place? It's not even a particularly difficult one! Though it is immensely effective on most of the female gender... that said, I do apologize if you feel like I'm stealing your idea..."

"Hey, I have no problems with it," Issei replied with a shrug. "First of all, consider it payment for helping me learn it to begin with. Secondly, if it helped you beat Yubelluna, then it played a role in us winning, so can't be mad about that. And most importantly, if there's anything I'm lamenting... it's that I missed it," he wept.

Koneko groaned as Akeno laughed. "Don't worry, we'll get a copy of the Rating Game footage later. They might censor some of it, but I doubt Rias will have any trouble removing that... Also, I don't plan on using it often. I'll probably just keep it in the back pocket..." Akeno assured Issei. "...side note, Yubelluna is pissed that I destroyed her expensive dress..."

"Fair enough," Issei nodded. "And noted." He turned to Rias. "Think you can produce an exact copy of that dress? Actually, of all the clothes destroyed by Dress Break during the Game? I might send those to Riser's Peerage as a small peace offering. He might be a jerk, but I'm not... at least not as big of one."

"Of course, Master, clothing is very tied to sex, so creating it, especially sexy outfits, is well within easy limits!" Rias nodded. With that, they approached the bed, and Rias pulled the curtain closed.
