At the beginning it's playful and flirtatious, the clothes come off and it gets hotter, but eventually it turns into something more passionate, and seemingly more real. As it goes on, it gets more intense, maybe even one person takes over and the other lays back and enjoys it (thus the guitar solo) and at the very end of the solo, it gets more and more intense and then the couple as to take a rest from the immense beauty of the whole thing... and then it slowly picks up again, the male tries as hard as he can, and in a flash...
...it's all over.
Keep it easy, Newgrounds;
