Now these are my kind of games. There are a lot of threads posted here already about this. First search here before making any new thread. Now let's see what we can do about this. I think most of these games will have a female protagonist instead. You will find more success in finding those games. I will mention all the games with this type of scenario along with female/male MC.
1.
https://f95zone.to/threads/rhodes-fortress-scalegarden.1826/ (Female protagonist, has a childhood friend, NTR)
2.
https://f95zone.to/threads/the-tyrant-v0-9-1-saddoggames.6025/ (If you replace friend with family it suits the demand)
3.
https://f95zone.to/threads/do-you-have-akira-points-final-golden-fever.26448/ (You met with your childhood friend and can romance her but no NTR option, great romance story though)
4.
https://f95zone.to/threads/amor-magical-academy-precious.1868/ (Start of this game contains unavoidable brutal NTR but after that you can either romance with your childhood friend, sister or let others do that)
5.
https://f95zone.to/threads/childhood-friends-v1-0-void-star.42697/ (very short novel, but only NTR, no romance)
6.
https://f95zone.to/threads/dark-hero-party-v1-01-u-room-kagura-games.3106/ ( no romance only depressing NTR)
