SuccuFuta

Not much to it as is, but what's there is promising. The sex scene is fairly lengthy, you can choose whether or not to cuck the dude (since he actually seems fairly nice), MC is surprisingly patitent and has hints of a personality beyond "lol im horny XD". No bugs, not too many grammar issues, no attempts at "deep" writing with zalgo text or whatever, just a simple, mostly linear experience.
