[Blargsnarf] Finn the Stripper Boy
http://exhentai.org/g/856232/eafd27836d/
This is part one, of this set. It may be older, but it's new to me, and it just showed up on exhentai. It might be newly finished. Essentially, Finn the Human goes to a party hosted by Marceline, and performs a striptease for pretty much every woman in the series, and also Peppermint Butler. I honestly wish there were more scenes like this in hentai, the idea is incredibly hot, and there's a ton of opportunity to make a fulfilling scene, for both men who are into the women watching, and women, who are into the boy performing. It just doesn't get done, much, which sucks ass. It really is a fantasy with legs.

This is part two. Finn gets pounded by pretty much every woman in the series. Like, they take turns pegging him. It's fun, the art style is very much like the show, so if you can't do western, you won't like this. There isn't much to say, I guess if you like the show a lot, this might be more your thing, because I'm pretty sure the characters are presented on model. This artist very much takes the "Marceline and Bubblegum are lesbian lovers" approach, which is what it is. I think these are decent, as a set.
