Black Silvia and her four henchwomen have turned your island paradise into a hell, and it's up to Sunny and her dildo staff to stop them. The enemies also have a similar rod, so as the intro says: "To advance or retreat, to win or lose, to stab or be stabbed, to pour or be poured into, to climax or be made to climax. Go, Sunny! Don't lose, Sunny, don't let your guard down!"

A simplified mahjongg variant with a board game / RPG element. Your character moves along, fighting enemies, with the tile combinations determining healing, damage, etc.
