I don't play a ton of H-games, especially since working on this project I just don't have a lot of free time any more, but I'm not aware of any major projects where this is a feature. Is this a thing I'm not aware of or are you asking for a novelty thing here?
Like personally, to me, looping during scenes makes sense because it's sex and it can/should go as long as the player wants, but an orgasm is a finite experience it only lasts for so long haha I feel like it would break immersion (I know, funny a game as goofy as this one is worried about immersion) to just have MC busting for 10 minutes on a loop
