Maybe because I use a translator, you misunderstood me a little...
In your game, the character is simply mismanaged. I mean, I can move it up at any time. There is no binding, no gravity. That is, I just don't understand why characters have avatars at all, if they are... They don't really exist. Here you need to work hard to shove the penis into your mouth. And it's not pleasant to work hard, it's just a strange, incomprehensibly justified hassle. I mean, if your main gameplay cycle is a blowjob, then it should function. SDT is very good from the point of view of the gameplay cycle, but it is very small in it, plus the game is terribly outdated. And have you... The gameplay cycle doesn't really exist. I mean, it's there, but it's just terribly made. Sucking sucks in this game.
To summarize: Do you want to focus attention on something other than what the gameplay is currently revolving around. Or you're trying to improve the game somehow, even though its foundation sucks. You should either shift the focus to what you want there, or do a normal sucking. Despite the fact that there are examples where it is done well (SDT).
