Li Oshiri no Hi (いいおしりの日 ) - Good Butt Day 2023 (Patreon)

November 4 in Japan is unofficially celebrated as "Good Butt Day (Ii  Oshiri no Hi)", derived from a pun on the Japanese writing of the date.  The number 11 represents a double “i” (いい = good), the number 0  represents a letter “o”, and the number four maintains its pronunciation  as “shi”. To the latter, the “ri” is added to create “ii oshiri (Good  Butt)“, which gives rise to this peculiar celebration.

And our dear Sapphire was very happy to illustrate this day.
