My brain is fried from studying Fourier transforms all day. The only equation I want to solve tonight is how many times I can make myself cum before my hand cramps up. There's something about that specific, aching need that takes over—when my cock is so hard it's practically begging for attention and my mind just goes blank. No math, no music theory. Just the raw, greedy impulse to stroke and edge until I'm shooting load all over myself. That total loss of control is the best fucking reward.
