Just to add to what's already been said, if you go the slideshow-esque route with it, you can subtly add things that change/grow over time.
It's a really good idea.
Lets say that it's a good old trainer game. You can show images of the girl in her cell/room, slowly passing from a straight proud standing position to a more submissive one, while her clothes also slowly change to reflect her increased corruption ; the room itself can also change to reflect this lewdness. And on top of this you would have a text saying something like, "You continued training her days...", that change to "... after days ...", then, "... witnessing her slowly give up ...", and finally (for the few last panels), "... until the moment she was finally ready."
With a slow fading transition for the images, it could give a good result.
For a game where the MC start to live with a new roommate, the images can be scenes of the day by day life, with the girl being strict and shy at first, then slowly getting used to MC's presence. At first she's always fully dressed, then she drop the sweater at home, then the shirt isn't necessarily fully buttoned, then its sometimes unbuttoned, then she can just show up with a maxi t-shirt, then eventually don't care to be seen in underwear or just wearing a towel. This taking part in more than just one room of the house/flat, and the room themselves have some changes. In the kitchen there's sometimes dishes waiting to be washed, or to be served. In the living room books are moving, there's sometime a bag. In MC room (or the girl ones if she's the one that moved in), there's more and more furniture and objects (showing that (s)he slowly make it his/her room).
As for text, it could be something like, "It was strange at first, none of us being used to live with a stranger...", "... but with time it was getting less awkward ...", "... until the day it seemed that we were always living together."
For a game where the MC will corrupt his female coworkers, it could take place at works, with scenes took an MC's desk, and in the break room. At first MC is relatively tense, and generally alone, then he become more and more relax, and there's people going to see him at his desk, and talking to him in the break room. Those peoples also become more and more relax, showing that it slowly pass from professional relation to something more friendly. You can also start to add scenes took outside of the work place, like an after work session in a pub, some karaoke night, or just the MC talking with few coworkers in front of the building.
And so on depending of the context of the story.
