Imagine waking up to a raging hard cock and feeling a set of 10 very long nails teasing it, playing with your cock until you get even harder. The only way to make it much better is with lots of oil - shiny and lubricated. Feel the fingers on your cock head, listen to the sound of the acrylic nails so close to you - the combination of feeling, sound, and arousal creates incredible conditioning which will affect your erections in the future. The only way to feel free is by letting Her have control of your cock, through slow, careful strokes combined with extremely fast, strong movements which make you want to explode right now. As I mentioned, She has control and she will play with your cock head for as long as She wants, because She cares about Her own pleasure. Whether you orgasm or NOT, that's irrelevant right now.
