Yep. Trophy requires also her to be pregnant. If you can use any cheat tool before the scene, you just need to set the FLG_CONTRACEPTIVE_SWAPED to 1 and any she'll be pregnant if anyone "finished inside" her during the game.
Thanks, tools like? You cannot use the "rosebud" input prompt (I have already tried by inserting FLG_CONTRACEPTIVE_SWAPED=1 but it doesn't work)?
Yeah. In the rosebud cheat console you can use "Player.FLG_CONTRACEPTIVE_SWAPED=1", but int only works if you do it BEFORE playing the final scene
