Not in Mainstream works, porn with BBWs that Japanese creators made, it could be live action stuff, or drawn Hentai. Not protagonists/characters from mainstream anime like Dragon ball, sailor moon, Pokemon, One Piece, naruto, Bleach, My Hero Academia, Yu-Gi-Oh!,
I was saying that most BBW porn done by Japanese creators, when they have men, they tend to be short and bossed around by BBWs who the creators draw to be super tall in contrast with the tiny thin men in these stories. I noted that Heroherotom does this, as does Squarewave29 in some pieces and artist Namio Harukawa. Bits of live action porn from what I've seen also has this, the dudes gettng bossed around by BBWs. Feels sort of BDSMy.
