I realized recently that, while they have appeared together here and there, I haven’t drawn Goku and Chi-Chi directly interacting in quite a few years. I believe this Ask is referencing an older one Goku appeared in with Princess Snake, in which she claimed he enjoyed footjobs and he agreed. I thought it’d be fun to see him enjoying one from his wife, who’s kinda the one I picture teaching Goku everything he knows about sex.
