Landscrape #3: The men in repulse

A young couple are kissing in a grove and are happened upon by three men who do depraved things:

Inside a grove,
Two lovers delight,
In playground pecks,
Preteen polite.
A rustle of leaves,
A stir from behind,
The band of black,
Sizing their find.
The couple's dread,
In quickened heart,
Three men in hunger,
Anxious to start.
Moist in the mouth,
Descent on the pit,
The boy’s neck seized,
Pallid and slit.
The First Man’s touch,
The girl in assault,
Stroke of the bog,
Her tears in revolt.
Her jeans undone,
Her lips in frown,
He raises a knife,
Plunges it down.
The howl of the girl,
A beggar unheard,
The hollow packed,
Second and Third.
Her visions vague,
And cavern’s clot,
A girl blissed out,
Sunk in the rot.
