Whose heart is not a hungry fish?

Accelerando by Cyril Wong
The lovers wait to lose their balance. They would dive
gratefully into the half-dark, picking fingers, thighs, lips
and tumescent parts. But wait, let’s stick to beginnings.
Before a rustle in the chest, there were first meetings

in crowds and along unremarkable corridors. A grin, a look
and the memory shrinks to the here and now, re-playable
for future use in the hour before sleep, the hours before
they meet again. Living is an endless piece of rope.

The lovers are jaded funambulists, steady gait slowed
by the weight of loneliness. But legs quiver now, the bait
already cast. And whose heart is not a hungry fish?
