The basic premise of this answer seemed pretty obvious to me from the get-go. Popularity is always going to be a big factor with things like this, and in the Studio there’s a direct correlation between frequency of appearances and fame. Of course, Natsu wouldn’t be the type to go completely without partners, but I figured it’d be fun to pair him with a bottom boy who also hasn’t had much spotlight yet. Shun’s one I keep thinking I’ll draw more often, and he seemed like the perfect partner for this Ask. On top of me wanting to use him more, he’s also got experience taking dick from pink-haired guys already.
So I’ve been revisiting The Disastrous Life of Saiki K. recently, and one character I really wanted to draw while the show was fresh with me was Shun Kaidou. We saw his mom and sister not long ago in the last MomSwap I did, but Shun himself is also pretty cute (as his his younger brother). Shun’s the type of character I just kinda want to draw being a slut for a bunch of different characters, but in this case I went with series protagonist Kusuo Saiki. Kusuo’s pretty asexual in the series, but he also has a bad habit of getting involved in situations he wants nothing to do with (his line in this picture being something he ends up saying with some regularity in the series). Shun’s whole gimmick is that he lives in a fantasy world, where he pretends to have secret powers contained by the bandages on his hands and is the target of a sinister cabal. Most of the early humor for his character comes from this, but I thought it’d be funny if he began incorporating ecchi tropes into his own internal logic. I feel like powering a superpower through cum like he talks about here is something I’ve seen a number of times in hentai doujins and the like. How exactly he managed to rope Kusuo into providing said cum I do not know, but here we are.
