A Sudden Kick

Whoa! My fingers actually twitched! I leaned forward, gave a sudden punch into thin air, and snickered. Everything felt weirdly real! Right in front of me sat a glowing rectangular block on the seat. Without thinking twice, I swung my leg and gave it a solid tap! Clack! It nudged forward across the dark bench, glowing faintly under the sharp blue shadows. Ha! I really can move!
