a ride and a question

"Very good, my new little ****. Now ride your master's dick."

Michelle tried to get over the pain she was suffering, and moved like she thinked she was supposed to.
After some times, the pain decreased and her body reacted to accept the pleasure of it.

Ivan put his hand on her hips to help her with the pace.

Without interrupting their movements, Ivan said : "You know that as my **** you must do as I say, and answer me truthfully, right?"

Michelle nodded.

Ivan : "Ok so from now, you must say 'Yes, Master', or 'No, master' like a good **** must be."

Michelle nodded but understood immediately and added : "Yes, master."

"Ok, you could understand that we will fuck very often from now and that I'll cum in or out out your pussy at my discretion."

"Yes, master." A part of the mind of Michelle worried as she didn't really know where this discussion going.

"Well, then to my question : are you in any form of birth control?"
