Birthday pic for Melangalade (Patreon)

 A quick birthday pic for Melangalade with his 2 diver girl OCs Dusk and Dawn. The girls planned a surprise where Dawn would jump out of the birthday cake to surprise the birthday boy. Unfortunately the cake is not water proof and she does not have gills. It looks like she tried really hard to stay inside for as long as she could but now she needs to get to the surface. Dusk seems to disagree...
Why are they underwater? Why not? He usually draws them in sexy diving situations so I will too. >:3
