In my opinion the best and most realistic NTR game next to Adventurous Couple. Maybe you know more games like that or have an other opinion.
Yes, apart from this and The Adventurous Couple, there is also : Exciting Games, Happy Marriage, Lisa, The Singer, Angelica's Temptation, Watching My Wife, Where It All Began, Jessica O'Neil's Hard News, The Office Wife, Project Myriam, Project HotWife, Inside Jennifer, Jasmine Hotwife For Life, Deliverance, Anna EA, Because I Love Her, Pervert Action Timelapse, EON, to name only the best ones..
To find more, try a search for the tag "NTR" whereby due to the mixed understandings of this term you may or may not find what you wish to find.
In my experience, the tag "cheating" is not what you need coz it usually refers to the MC fucking a lot of girls so you can find it even in harem games. But it does not imply that a Li is fucking other men..
Normal western words like "sharing" or "swinging" are hardly used in tags, "open relationship" .. unfortunately not at all
And when you find "swinging" in tags you can mostly expect some 3 somes, mainly FFM, seldom MMF, which are in fact "group sex" but not swinging in the classical meaning (which is 2 couples swapping partners).
So the best is to search for "NTR" whereby you can naver know if you find netorare or netorase.. or both.. or none.. and just some group sex with more women and no other men
In many cases, if a Li has a relation with another woman, that is also tagged as NTR, although it is not..
However the games i named above are really good and if you like this kind of "kink", you should try them all
