I Have a Secret

I sit here next to you,
But I am thinking of him.
I honestly know what I have to do,
But I love the feel of this sin.

You are my best friend,
And he is a great love.
I dont want our relationship to end,
But then again I dont want to shove.

We kissed each other at a party,
Something that felt so right.
But I still feel your part of me,
That wont disappear overnight.

So what am I to do,
What more can I say.
I have kept this one secret from you,
Hoping for a better way.

So I sit here next to you,
While I am thinking of him.
I know what I want to do,
But you make it feel like such a sin.
