Might be worth mentioning that the new game up: 戦乙女ニーファ ~女難のショタエルフ~ Has a mechanic that lets you raise both lust and love of all party members, it's really easy to manipulate as some scenes in your house can be repeated and when the Main characters have high enough love with each other the defeat scenes(and some scenes in town) will take the perspective of the boy getting NTR'd and with high lust the girl will eventually give in or else it'll just be her crying for MC instead and not wanting to be seen-. Some boss fights that you lose against will keep the girl held captive and you can either try to rescue her yourself or go to town for help. If you go to town you can bring another girl with scenes that is stronger- but can also still make her lose the fight for ANother scene, which will bad end with another CG of her being forced- and then the scene of both of them being forced together and the protag is helpless, or you can bring a shady man to help and yeah. Not a full blown NTR game but definitely has the routes giving it the potential and the art is very good. There's also multiple variations for every scene depending on stats and it even changes the CG depending on costume worn for each. It's one of the better made rpgmaker games in recent memory i'd say. Figure most people in this thread are looking for VNs but just adding that the aspect is there.
