What future tags are you planning? Harem? ntr/sharing? Pregnancy? futa/trans? femdom?
I would sincerely advise against making NTR content lol. That would put too much on your dish, and steer NTR-avoider like me clean away from the game, while may or may not meet the expectation of NTR-enthusiast (as far as I know, they are EXTREMELY picky and won't support unless it has a compelling story or rub their specific spot).
