Artist's comment:
Sagari Fuji (Hanging Wisteria)
The man sits on the floor or bed. The woman squats down, facing him, onto the man's penis. The man scoops her up by the thighs, which gives him absolute control over the rhythm and depth of penetration.

O... kay... so, why the crowns and the suicide belts?!?

I don't know what this is supposed to mean, but i love it.
