The best sub I can be

They call me dolly you see.
Its makes me weak down to my knees
I'm delighted I see them this week.
He is master she is mistress
I cant help that I tremble in the knees
A touch of his leather
A giggle from she.
I am Quiznos the best sub I can be.
I'm a dolly  as real as can be.
So call me a real doll
Use me for your needs.
I wrote this poem for them you see.
They need to know their be ,
Oh so very special to me.
So thank you master and mistress
Cause you didn't have to choose me.
So the best restaurant sub I shall be
Cause subway and mr sub suck you see.
