She understands very well

Swallowing thickly, Sasha shudders at the thought of being broken in by him, but forces herself to stay calm. "Yes Master. I understand. If I serve you well, you won't… use my body until we're married. Right?" The thought of being used like some whore makes her shiver, and her mind wanders to what he could do to her if she failed him. He chuckles at her distress, enjoying the power dynamic, before pulling her close and kissing her deeply, his tongue dancing around hers. When they break apart, he says "That's right. Now, my ****, why don't you show me how you can serve me before we have to start our day? I did promise to let you keep your dignity in public after all."

Feeling the heat rush through her body as she returns his kiss passionately, Sasha's body betrays her reservations. She pulls away from him and looks at him seductively, running her hands along his naked torso before leaning down and taking his cock in her mouth. He had to admit, she was acting much more proactively than he expected. John was certain that his threats of knocking the (unexpectedly very cute and obedient) bitch up with a bastard would be effective in keeping her subservient, but he didn't think it would work so well. He groaned in pleasure as she sucked on his member. "You're learning fast, it seems that I was right in not ruining you right away." he encouraged her.

Moaning quietly at the praise, Sasha takes him deeper into her mouth, sliding her tongue along the underside of his shaft as she massages the base with her hands. Her eyes water slightly but she ignores it, intent on pleasing John. "Thank you Master." she mumbles around his cock, eager to make him happy. Without a reason to delay his release and under her careful attention, his cock begins to throb as he's about to come down his new servant's throat once more. He'd get bored of it eventually, but for now it would do.

As she feels him getting closer, Sasha redoubles her efforts, sucking harder and quickening her pace. When his cum floods her mouth she gulps it down greedily, moaning quietly around his length as she cleans him thoroughly.

He stared at her lovingly, thinking that perhaps this adorable girl throwing a wrench into his plans wasn't so bad after all… "We'll need to take a good shower after everything that's happened." he commented before leading her to the bathroom.
