A fantastic original deluxe shunga woodblock print picture by Koikawa Shozan!  In this shunga scene, a postcoital couple is being interrupted by a large shi-shi (lion dog).  Making the scene even more odd is the fact that the woman is also caring for and holding her child - while wiping up her privates!
