I am sorry to say it, but I am still totally confused by the sex scenes. Most of the buttons don't seem to do anything, and it seizes up randomly. I can't tell if hitting the right buttons is supposed to affect the scene outcome, and some of them are mysterious (like the one that depicts a sinusoid curve.)
It works a little different depending on what version you have, but here's the basics:
1. On the list of icons, click on the white box. That brings up a list of available positions. Click on one, then see what the woman says. If she says "change the position", then pick a different position. If she says "faster" or "harder", then go to the icon that looks like a speed dial.
2. On the speed dial, slide it up a bit. If she says "faster" or "harder", slide up more. If she says "grab my legs" or "pull my hair", you've hit the highest speed she can take. If you find her saying "it hurts!" you've gone too far and she gets the crying eyes, you monster.
3. As you are fucking, watch the "orgasm" meter at the bottom. Once she hits 100%, she will cum.
4. The "cum" meter tracks your pleasure. When it hits 100%, you will cum. In newer versions, you can shoot a load at will (hit the icon that looks like a SPLAT mark) and it won't affect your cum meter.
That's the basic premise.
As far as the other icons:
- The Tie: Lets you pick what clothes, if any, the participants wear.
- The Play Button: Not sure
- The Crossed Arrows: Switches to a random position. Stops working for me once you cum once.
- Wavy Line: Changes the rhythm. Sometimes this button works, sometimes it doesn't.
- Double-Sided Arrow: This is for orgy situations, which you can't really get involved in until you have a studio or a special event.
