Her slut

I choked hard upon her cock of rubber,
For mealy looking upon another, I was made to suffer.
If my eyes wandered and my mistress noticed me,
For wanting to be a slut then a slut I shall be.
But roles reversed for I shall be her slut and hers alone,
Unless she wished to watch her friend use me whilst sitting upon her red velvet throne.
She enters me from behind whilst I pant on all fours,
To be left as her bitch is my mistresses most noble cause.
She pressed against me and draws me near,
A simple dog to be taken from the rear.
Once my arms grow weak and my legs unable to stand,
She flips me onto my back and my shaft falls within her hand.
A tightening grasp squeezing flesh and vein,
My prostate milked but unable to cum drives me insane.
Only once my mistress has had her fun,
My arse is sore and her pleasure is done.
This is when her hand releases and all manner of fluid does flow freely,
She pulls out and I'm left to clean her off hungrily.
To taste myself upon her corset and skin,
This shall be the epic end to my heavenly sin.
