I know you love mindlessly pumping your dick up and down for me until you cum. But you know what's even better than that? Cumming for a challenge. Today you're going to stroke the hard way. You're going to cum for me if you can. If you succeed in my challenge, you earn a big orgasm. If you fail, you'll have to try and try again. Stroke your cock up and down ten times, getting it nice and hard for me. Then...hands away!  The challenge begins now. For the rest of this clip, your masturbatory range is limited to just the tip. No more stroking the shaft. It's all about the head now. I'll teach you different ways to stimulate the tip of your dick, showing you how good this masturbatory focus can feel, as I make your cock head drip and twitch. Sometimes less is more. Like right now. Just the tip -- it's all you need.  And THEN the cum countdown timer begins. Can you make that cock cum for me with just the tip? Let's find out.
