There's only one CG with our MC as of right now I think. Near the very start of the game where you can give Gunnar a blowjob on the Tracks.
But I also saw something on twitter from one of the artists of this game "StanGArt" I think? If I remember correctly, they've done some CG on this game. and there's possibly a top MC CG during your date with Bernard at Northcrest. I think? I wouldn't know though because my character isn't a top. That or that art was just fan art by them as well. Anyway, all I know is there's only one MC CG yet at the moment.
