anyone knows, how to play this game? I'm trying and clicking and get sometimes another picture, but I don't come to a real game

I've tried it a few times. If you double click just below her mouth, she will lick your cock but you have to double click below her mouth a few times and each time she will go a little further.
The same goes for her breasts. If you double click her chest, you can squeeze her breasts. Each time youdo it, you can squeeze her breasts a little more.
If you double click her skirt, you can open her legs. After about the third time, you can touch her pussy but I keep getting a dialogue box where if I click yes, nothing happens and if I click no the game closes. So I haven't gotten any clothes off of her yet and according to the pink progress meter on the right side, I've only done about 25% of the game.
