This might be the most wholesome foot fetish comic I've ever seen.
Hell, I don't even think Lincoln likes Ronnie Anne's feet in this, he was just trying to tickle her (he also goes for her ribs). Ronnie Anne's the one trying to turn Lincoln into Quentin Tarantino with her constant smothering, and it didn't work seeing as how he set her free pretty soon after she began foot domming him.
I don't even know if this is intended to be a foot fetish comic. Could just be Lincoln/Ronnie Anne having fun with the author's bondage fetish creeping in.
