Responding to some of what you said, I'll have to give some thought with the rest.
He is ruthlessly obsessed with research and research only, so unless banging his daughter somehow helped his research, it's unlikely. I doubt he augmented his penis with sensors to "research" the cavities of his daughter...for SCIENCE!
There's sexual things one can do without insertion. Also, not his daughter and she wasn't in a rational mindset in the beginning, she's told a "cartridge" is a girl called X and she doesn't blink at all. She was incredibly far from any social normals, her mind broken and reformed, at least TWICE.
Prushka was part of Bondrewd's research and his goal was to make Prushka love Bondrewd above all else, before being inserted into a cartridge. Banging her daughter was therefore too risky and out of the question...unless it was part of his plan all along, to make Prushka love him even more...but that too seems unlikely.
Again with the banging, pleasuring her would make her love/devote herself to him more, probably. And maybe he allowed her to investigate and explore him in return. Does Bondrewd's character seem like he is risk averse? Especially when it comes to the welfare of children. The risk/reward is probably a little different than you think too.
I considered the possibility too at first, but ditched the thought since it doesn't fit Bondrewd's character at all.
Him being careless in a way that would cause her to see his penis in a large mansion size structure with many locking doors does not seem at all in character. The clues on that page mentioned before, I don't see any other way to take them then her having seen his erection (well technically someone elses erection, since he borrows bodies, original bodies probably lost even) And it also implies she saw how he got the erection.
And what the hell with them letting Bondrewd survive. Why didn't they break the mask? I thought they already knew it was a aspect of his body swapping. And did they destroy the main body swap device? Riko was in the room with it, but they kind of glide over that. All that desperate survival against him and trying to kill him because he's so bad, and they just shrug about him surviving and seeing them off?!? Won't Bondrewd keep using kids in horrible experiments and as cartridges?! Also, was Regis arm reattached? I can't remember if we were told after.
Regarding Nanachi'
Ok maybe he rubbed to her underbelly then? We know that he finds the smell down there especially good. And I get what you are saying about it being a general wish for being liked, except where the best smells come from aspect. Also, Nanachi can take care of herself, but then again he is a cyborg or whatever with high strength and while embarrassed and resistant to a degree, she wasn't totally adverse him touching her either. It was implied with her saying "now you know how it feels" with those things reaching into Regis pants, that he had managed to pet her in sexual ways any of a number of times before, even if we quibble about which ways those might have been.
Also, Nanachi expressed something that sure sounded like sexual arrousal regarding Bondrewd a few times, calling him attractive or whatever, despite her general hate of him (during battle with him and after, of all times) And Nanachi was assistant to Bondrewd for a long while after she got turned into a bunny. (why did she do what he said after that, hurting kids on his behalf?) Which goes to both Bondrewd possibly doing sexual things with the young girls and to Nanachi having a bit of a extra sex drive that isn't typical for a young kid.
Regarding Riko and her punishments.
Former punishment room, Riko's room", meaning that the tools are no longer in use. Why keep it then? Well, it's still very effective psychological tool for scaring children.
Why make it into Rikos room then? Behave or we will take you to Rikos room? Yeah, I don't see a threat like that being effective. No longer in use, but you think they may have been in use before? If the tools had never been used, wouldn't the kids pick up on that and not be scared?
Whether Riko took a few items or many items, whether she was electrocuted or any of the other nasty items in the "punishment room" were used on her or others, or not...
1. We know that at the very least she was hung naked in that horrible way many times. It tells us exactly that at one point. And since no picture accompanied it telling us it was done many times, the point was not some fetish drawing by author/artist only, and was well past the point of establishing her being a energetic troublemaker or whatever, in the story.
2, Her being hung like that naked would cause great pain and damage. This is not some minor thing, it is torturing someone. Plus since kids are growing and repeated distortion of the body as someone grows can badly affect their growth. Like how Japanese girls forcing their feet into shoes too small because of ideals of small feet warped their feet growth. She'd probably at least have scar tissue from it as well as permanent mental damage.
3. If it was private, there wasn't much reason to do this with her naked, unless they wanted the ropes to damage her young flesh as part of the punishment (or wanted to see said flesh themselves) If it was public, it would be putting her on display, either way, sadistic and extremely excessive.
4. This torture, was repeatedly proven useless, and even counterproductive with both Riko and the others (and would be much more so in real life) yet they kept on doing it and not trying other things. Meaning the goal was not "reforming" her, but the torture itself, which makes those who do it, sadistic. And we know the old lady made threats regarding such, meaning she was the one who decided such, and probably saw to it herself.
Also, the white whistle lady using it on her child assistant after commending her for the very same thing she was torturing her for. Like, "Yay, a excuse to torture a naked young girl!", and we know she was twisted.
