Metronome Challenge for Solo Overwatch Jerk Off scene

It's a solo jerk off challenge themed around Overwatch, with the whole thing set to a metronome. The guy starts stroking to the steady beat, trying to keep the rhythm. He's focused, looking at the screen, working his hand in time with the clicks. The pace is pretty nonstop, no chance to slow down or speed up on his own. You can see the tension build as he gets closer, his movements getting more urgent against the unchanging tempo. It's all about that forced rhythm, a challenge to finish before the timer or just keep going with the beat. The climax hits right on cue, a messy finish that proves he kept up with the Overwatch-themed jerk challenge until the very end.
