Lust  (how deadly is this sin?)

Pleasures of the flesh include
A range of human action
From gentle touching in the nude
To sexual penetration

The bewitching feel of skin to skin
The  sharing of a passionate kiss
The tingle when the penis goes in
All these are too good to miss

The sharing of an orgasm
Is the height of ones longing
Creating such a mutual spasm
That will last until the morning

Why is lust such a sin?
When such actions are so natural
Two are needed to join in
But the feeling  must be mutual

It is a sin to impose
Ones self upon another
But not if both chose
An act of  lust  together
