On the bus

His knee covertly inches
by fraction of millimeter;
almost brushing
before edging away
seemingly random rhythm.
Watching others - shifting;
excuse for quick glances,
subtle knee advances
Turning to window - hiding.

Sudden bumpy turn,
losing control
his knee swerved
their jeans touched
not entirely
by accident.
He trembled,
coursed with painful desire
scorching through denim.
