Surrogate

The desire they held for each other
was not supposed to be.
The appetite i had for them
was insatiable for me.
I was a willing participant,
a surrogate of sorts,
i let them use my body
for their licentious sports.
While he refused to touch her body
and she dare not touch his
my own was not restricted
to either of these twins.
Each had me while the other watched,
imagining together
until the day their shame crept in
and broke our bond forever.
Can you really blame a girl
for submitting to her desires
particularly when those involved
are quenching their own fires?
