Very nice! Is the male figure in this picture the same character as your recurring tall female with the horns, from other illustrations, who's transformed herself into a big dominant man here, to ravish the male-turned-female subby slave?
If so, that's my #1 one sexual fantasy; to have a sexy, beautiful woman impose a magic-based TG transformational swap with me, trading sexes, sizes and gender roles... and then, as a handsome and powerful hunk, completely owning me, an incredibly cute and feminine little curvaceous hottie, in the bedroom. So totally hot!
