It was late at night
I heard an echoing
Of heels...clicking
On the sidewalk

I could see shadows
Through the trees
Two lovers kissing
On a park bench

I stood there...frozen
Watching. . .
Waiting. . .
Wanting. . .

I heard zippers
Unzippening. . .
Hands moving
To pleasure each other

She slipped onto his lap
Guiding him...she rocked
Back and forth
Their moans carried them

To thrust with greater force 
They came simultaneously
Together, they walked
I was an accidental voyeur
