I personally disagree. I like the image to give an appearance, but in this case most of the scenes are written really well, so my imagination does a better job than videos would. Defeat images could possibly work, but again, text does it really well to begin with so why risk it?
Well it's all depend on people perspective. Some people don't have a good creativity and need a image/video to help them, and some people have it. I specially just want a new art/image when you lost the fight, like a new image on what scene you lose. If you lose in handjob it's gonna be a new image where you got handjob by the enemy, or when you lose while in sec stance, then it's a new image you having sex with the enemy. And it's still has the naration (the text) but with a new image. Not just the same as when you were fighting against it. Try looking for death/sex scene from game named "Monster Girl Quest". That is what I want and mean from the comment before.
