As i mentioned on the discord(posting again here for the eyes of anyone else looking.) :
-Snail of approval’s Supper Fatty RPG: Super Fatty RPG: Full Version!!! - #84 by jak8714 it is not specifically male centric, but the gender of the MC isn’t specified but does not have boobs unless though the in game events you give them boobs.
-Geek dragon’s Gaining Perspective: Gaining Perspective - Weight Gaming
-Fetish master also has male content (though males do get cut out of some content.)
There are others who i’m sure have slipped my mind at the moment though
