To be honest the last sex scene was somewhereNuh uh, but in FOG, she only had consensual sex with Inoda a couple of times. However, according to Fujino sensei's recent progress report, we might see an irl scene in the next upcoming update. Still, I doubt we'll get a full sex scene yet lol.
between FOG and IRL, she was online he was not
About the relationship is almost inexistent, I can't remember when was the last time they had sex.
This is kind bad because take away her sense of guilt and the mystery of the secrecy of the story.
If they are doing nothing together to validate the betrayal which is the fun in NTR plot we end up with a Cuckold voyeur plot
