A wonderful original deluxe shunga woodblock print picture by Koikawa Shozan!  In this somewhat busy & odd shunga scene, some sort of celestial being takes interest in the seaside lovers.  Meanwhile, neither the man nor woman seem to mind the woman's daughter being present (pinned underneath her!?!?) during their sexual bout.
