That's certainly possible. Something clearly went wacky with her programming this morning  and that may be part of it as well.GouryG wrote: ↑Mon Dec 10, 2018 7:52 am"fully functional" human female but she had limiters built into her program to keep her activities PG rated. Now between Largo's hacking and the evolution of her programming these limiters may have been overridden or deleted and now she can do many things her programming would not let her do.
But Ping has always had the ability to do sexual stuff, even though she's a non-H model: "that part belongs to me. It's not part of any game." . I think the fact that she's doing this for Junko makes it meet that criteria. Ping has always been self-sacrificing and willing to go way above-and-beyond for her friends.
So rather than (or maybe in addition to) software glitches and changes, I think the problem is that:
a) PIng is misunderstanding the situation
b) Ping doesn't realize that Junko would be horrified
c) Ping needs to value herself more
That last one is the biggie, I think.
