great game.
also to follow up on donatiel25's general summary of how to get everything, a FullNelson position can be unlocked. after you get the alternate breast bouncing animation (the one where she sticks her arms out), click on the anal or vaginal option (blowjob doesn't have an animation since it's mostly done on the ground). you should see her with her hands out with the peace sign. also worth noting is that if you do the Missionary or DoggyStyle sex, you can click on her eyes to show tears (only works when heart meter is full as far as I can tell). hope you enjoy!
