An unfaithful Lover

It seemed to start ever so simply
A kiss, or two, maybe even three
Exchanged between you and me

A hot scandalous sexy liaison
Causing serious complication
A purely sexual lewd attraction

I know you belong to another
You are the wife of my brother
My society forbidden lover

I am very attracted to you
Watching everything you do
You are more than a screw

But caressing your lovely face
Secretly meeting at your place
We share a lovers embrace

Our sweaty limbs do entwine
Your body so close to mine
A feeling so totally sublime

My brother and I now share
So much more, I do care
My lover, I do not declare
