@Starbright except that they aren’t progressing at all, in this way. She is the one who selfishly decided the whole “ban” thing; that gave problems for both of them, but when things didn’t went as expected, she is the one that leaves. And without any logical answer, too.
Plus she is ignoring him.
The right solution* -considering that she is as much of as a pervert as him, but she keeps acting like she’s superior- talking would have been an easier and proper solution. Not this dumb idea straight out of nowhere.
I’m not into ntr and I don’t think anything bad will happen in the end, but if something happens Kotoka has only herself to blame.
* n.b. “solution” to a non-existing problem: they are both perverts, and they are in love with each other even over the fetishes; it was already extablished, so I don’t get what proofs Kotoka is searching for, also.
