I’m talking rule 34 content, mods, and games designed to be used as wank material.
I’d say mine is Hotel Harem. It’s a lewd game that’s still in development that has been around for a while.
I was struggling to think of what specific character I’ve masturbated to the most but then I realized it’s definitely Tifa Lockhart despite me never playing Final Fantasy VII.
I’ve never played the game, but when I was a pre-teen there were a lot of ads for Final Fantasy X-2 and they featured a blond character with her thong showing. Made it very difficult to read my Nintendo Power without having to relieve myself.
