A superb Japanese erotic art shunga surimono picture of an elaborately and distinguishedly dressed couple sharing a sexual encounter next to a fast-moving river.  The female beauty assists in placing her lover's penis inside her open legs.  Her attire (and high-class stature) is further accentuated by the dragon-motif headdress she adorns.
