Let's be honest.
This is what the overwhelming majority of dwellers on this site (and quite a few others) would do if they reincarnated as a slime and ran into any viable girls or women.
i mean, running around killing and absorbing all the different magical monsters to gain all the abilities possible in a new fantasy world is essentially my ideal superpower i'd want in an isekai situation
to the point the 'reincarnated as a slime' was sort of a basic synopsis of one kind of playstyle of my 'ideal' game, if i were to make one without any limitations...
edit: someone mentioned some similar anime - the arifueta one where dude's like 'fuck society, just gonna conquer dungeons and fight a god' is essentially another.
but might not mind this as a diversion.
edit: pretty familiar with that 'slime hentai doujin' mentioned above, really. and the author's other works. it got to a certain point where you go 'fuck, this took a dark turn', i then noticed the author and went 'nevermind, surprised it didn't go way darker even earlier.'.
