This artist Minami draws stuff that's such a great mixture of cute and erotic that I didn't think was possible.

small feral Pokemon often have an unspoken lol icon dilemma no matter the media. But I like these three a lot. Is lolicon immediately applied to the lake guardians?

No.

Same question applies if you make a small feral Pokemon, especially first base Pokemon sexy, kinky, and used like living condoms and other kinks.

Like, where is the boundary that is considerably important to keep in mind?

This is why I like this artist a lot. It has my style and set of kinks that are often underserved.
