Didn't read it so no summary again.

I'm guessing this series will end (not anytime soon unfortunately) in one of three ways: with an orgy with the 4-5 couples we have seen since the start; this chick forgets about swinging with Seiji (or whatever his name was, I've already forgotten) and gets NTR'd; or the series will continue forever, just switching from couple to new couple until the series is bled dry (and maybe then end with a massive orgy?)

Just in case someone is still interested in the series, I'll keep uploading for a while more until I run out of the points I have stored on dmm (4 more chapters)

thanks for sharing

我算是看出来了，诚二上辈子是拯救世界了吧，每加入一组男女，女的都想跟他干，这新来的更离谱，专门交个模特男友想要交换，下一话估计是给男模特引个入门，后面还是要转到城二那两对里。

So the new character that was supposed to like the other guy started to like this guy now? I'm genuinely confused

What is this shit lol

越看越觉得这男朋友挺倒霉的，当个正常人太难了
