Lingers - a poem

I smell it on my fingers
I taste it in my mouth
Its aura really lingers
As your hardness moves in and out

Up and down, around my tongue swishes
As you slide to and fro
All that's stuck are silent wishes
To hope I can rinse and you will go

I spit just once
But rinse twice or more
For in my mouth I don't care for the taste
Of that funky goop left by my toothpaste.
