Entertaining the Darkness (Patreon)

Commission by a Pixiv FANBOX user through discord!

Darkness (KonoSuba) is stuck at the bottom of a pool, waiting to be rescued by someone because she can't swim or even float due to the weight belt around her. Realizing it might take a while, and with air to spare, she decided to have some fun all by herself...but it looks like she went a bit too far.
