Clarify your relationship with Sandra

Sandra has collapsed to the floor of the shower. Her legs bent at somewhat odd angles beneath and away from her. Pearly white seed oozes lazily out of her well fucked hole. Her eyes are closed to thin slits and head lolls a bit as she moans in pleasure at the fucking she just received. On her neck, a nice bruise has formed where you gave her a hickey - the first visible sign of your ownership over her body. Soon enough, the flat abdomen will swell with your seed granting you a second and more permanent sign of your new relationship with the gorgeous slut on the ground before you.

You grin down at the sight... your cock still a steel bar as you consider plowing into her again... and dismiss it for now...

"Sandra," you say firmly.

Her eyes remain closed and she mumbles questioningly, "Yes?"

"From now on... when we are alone, or when we are having sex... you are to address me as Sir... and I will not call you by name... no you must earn that by being a good girl... for now when we are together... I will call you Pet"

Sandra's eyes snap wide open when you tell her that. She adds, "Yes... Sir..." Her hand goes lazily to scoop up the seed that is flowing out of her in an attempt to push more of it back inside her juicy cunt.

"Don't worry about that for now Pet..." she shivers as you address her by the new name you've given her. Her hand almost immediately moves away from her slit, but she pulls it up toward her abdomen. You continue, "You'll be getting plenty more sperm from me in the future as long as you're a good girl..."

"I'm a good girl..." she says meekly and looks at you hopefully.

"Perhaps... you know everything that good girls do right?"

"I hope so... Sir..."

"Tell me then Pet..."

"Good girls don't use birth control so that they can stay fertile for their man... Good girls let their man fuck them and knock them up whenever he wants..."

"Excellent... Also, you should remember that good girls also help their man to find new good girls..."

"I understand... Thank you Sir" her pause before addressing you as Sir is a little shorter each time. She is becoming more accustomed to it. Good. That deserves a reward. You grab her and pull her to her feet. You take another kiss from her, your tongue essentially fucking her mouth as you assert your dominance over this woman. She melts into your embrace until you decide to stop.

"Now... do you have a diaphragm?" Sandra nods, "I want you to only use it to keep my seed inside of you from now on..." you stop and think for a second before adding, "unless I tell you otherwise..."

She says, "Yes Sir... right away..." she pulls her robe off the floor and quickly dons it before scurrying off to do as she was told. Your hand gives her another smack across the ass just before she leaves.

You finish your shower and ponder what to do next...
