I'm going to hurt you for this stroke session in a famously painful way! It won't take anything but a little knick on your skin. Doesn't sound so bad, does it? Just a teeny little slice made by the edge of a paper on the underside of your cock head (aka frenulum). You can do that for me, that's easy! It's not weights, needles, clamps, or smashing any of your parts. Just a thin, inconspicuous little slice. Next you'll need to get a little something to stroke with and it's very specific. Get the lemon juice. Now sit down, shut up, and get ready to pump that bitch dick.
