On yet another visit to the sperm bank, I crossed paths with a different donor. At first I figured he’d be like the rest—modest in size—but then I caught sight of his thick, pale cock, and my curiosity spiked. I lingered nearby, eyes locked on him as he stroked toward the finish. When he finally unloaded into the cup, the sight sent a rush through me: I started grinding my hips, twerking right there while touching myself, completely caught up in watching every pulse of his release.
