Sketch: Cerulean Moon / Ganymede X Mercury (Patreon)

When Io is away on trips, they'll sometimes ask Ganymede to make sure Mercury is safe and cozy while they're gone. Ganymede is more than happy to oblige since Mercury is such a sweetie and since both of them very much enjoy being soft together... and on each other and in ya know, certain places... like a big comfy bed! : 3

Seriously, they have a lot of fluffy blankets and giant pillows. This moon gets cold!
