Well that's certainly a straightforward title. Also Netori. That ending though. I have to say, they, more so she, didn't exactly do a very good job of...hiding what they were doing while on the phone. What a coincidence, though? That they both essentially called at the same time to ask about their respective partners. Would certainly be ironic if the both of them were...together somewhere, doing something similar. A 4P though...as interesting as that sounds, I'd much rather find out the content of those...texts, as well as how he plans to remedy the situation.
I don't know... I don't think so. The girl (Sakura) said that she had her first time with the boyfriend a little time ago so...Maybe after they find out? But then again, it would go from netori to swapping/cheating and maybe some ntr feels. (And I kinda hope it won't go like that)
