A wonderful original deluxe shunga woodblock print picture by Koikawa Shozan!  In this shunga scene, an upper-ranked samurai holds the leg up of his lover as he penetrates her deeply.  Her curled toes, facial expression, as well as her own ejaculation dripping onto her robes suggests she's in the midst of orgasm.
