Oh you're going to love this! All you can stroke! Get set! Steady! And Pump! Yes! Pump your cock excessively, pump to the clock countdown! Pump and surrender! Follow the clock! It feels so good to pump to my tits, watching that countdown, you can take your time. That is until there's another one? Wait, did it just change. Fuck did it reverse? Oh it's a mindfuck, your cock is just harder from it, it's unpredictable! And you need to keep your eyes set on the countdown! When will it finish? Oh it's so close, so fast! So slow! And the pumping just feels so good. Lose yourself in the jerk.
