Mate look at the game. You are literally a rectangle. This game is meant to be simple so more content can be produced. If you add animations suddenly you don't draw one sprite but 10 or even more depending on the quality. And so updates will take 10 times longer. I still recommend this game 2 you but if you want animations you won't find many good games in the NSFW-market. Especially free ones.
If I'm not mistaken "The Headmaster" has a good chunk of animated scenes.
Otherwise try "SpunkStock Full Demo". They move based on the beat.
Ok those are good games but ima not read the whole messege, just here to say, yeah sometimes thats how it works, and, welp it will be something else in the gb"s to have 348 videos or gifs of a ultra hd penis with 456 differents items in it that you can equip in 200 diferent colors.
do you see were im going?
But still, its good to dream
