The game is mostly cuckold focused. There's a route where you don't have to share but as described above it's kind of boring.
The actual cuck route has nuances to it. You can structure it so your protagonist has the highest likelihood of being the father of the child, or you can make it so someone else like Saul is the father. You can also choose to make some one sided deals that turn you into an exclusive cuck, or you can lean more towards sharing where you can fuck other women and get them pregnant too. So far I think you can only get 2 of them pregnant.
Interesting so you'd recommend playing it then?
Also with this This game feature light "NTR", pet play, humiliation and bondage - I assume this is more focused on Lisa rather than her fiance or is it a mix
Also I assuming there's some obvious cuck kinks that make you more cuck like eg cleaning other people's cum etc
What way do the other kinks work towards the MC with out massive spoilers like is it easy to get tripped up by something and end up fully cuck sort of thing
Also you mentioned a route where you dont have to share I assuming it's not a loyal partner route but instead is a mix of it with some aspects of unavoidable NTR
