A little while into the area of Rhodes, the first area of the game, you will drop down into a bath-house/sauna type area. Instead of continuing and diving down, jump out of the water onto the area around it. There should be two screens which are breakable. Behind one of the screens are two topless women. By walking up to them and pressing the circle button, you initiate the sex mini-game in which you complete a series of button presses. When you have won, you will receive a large amount of red orbs and some green orbs. You can only receive the orbs once, however you may play the mini-game as much as you'd like.
