I'm pretty sure that the office would've been legally within their right to sue her friend and the tabloid for conspiracy to commit defamation of character, but then I realize this is hentai and not within the bound of actual reason, and then I realize that this is likely based on a half-truth of the idol industry in Japan and I just facepalm.
I'd be pretty bummed if I got to fuck my idol, and they would just replace my dick with a dildo in post edit. That's like taking a photo with a celebrity, and you just get replaced with a cardboard cutout post edit.
......Well, I suppose this is what happens to idols in Hentai.
I feel like a concert like that wouldn't even be allowed to happen due to decency laws, or something, unless it's like an underground concert, but who am I kidding? It's Hentai, of course it'd be allowed.
