Start to lick the tip to show him you want it but tell him not here

The closeness of his black cock is having a strange effect on you, the heat and rhythmic pulse of his cock is somewhat hypnotic and you have a burning desire to open your mouth, but reason tells you your mother could disturb you at any minute. You start to kiss and lick the head of his cock before extracting yourself from the position you are in. You stand up and look him in the eye.

"I'm sorry, I do want to, it's just that..." You leave the sentence hanging.

"I understand and you're right, there will be plenty of time for fun. Besides, I came up here to fit this."

He pulls from his pocket a silver bulb and what appears to be a tube of lube. You look at him quizzically.

"It's a butt plug. I'm going to insert it in your ass and leave it in overnight. It will stretch your ass out so that way when I do start to fuck you it will be a more pleasurable experience for both of us. Now drop your pants and turn around. It won't take long."

You're unsure as what to do; on one hand having your ass hole opened up sounds like a good idea, but on the other, is a lump of metal the first thing you want to penetrate your ass?
