You follow Mary to room and with a lewd grin declare "'I'm ready are you Mary..."
Mary swallowed the brothel's special potion then moaned with need and smiled back "Yes John, I am now please take me..."
You then tied her hands above her head before you looked down on her body and felt it was perfection, supple, soft, curved in all the right places. And even better she was lost to her need, all reason stripped from her, all restraint gone, unable to think beyond pleasing you.
You grinned as you took her, teasing her slowly, making her want you all the more as you held her, controlled her, dictated the terms of your coupling.
"Beg me Mary... Tell me how much you want it..." you crudely asked her.
"Please! Please give it to me!" she gasped, almost frothing at the mouth. She rubbed herself against you and your member, clamping her slick, warm thighs around you in supplication. "Master. Master! Please, Master fuck me, fuck your slave!!"
At that moment you felt your dominance of Mary was complete. So you generously decided to give her what she wanted as she had capitulated to her potion slave urges and, well, you wanted to as well obviously. You thrust into her. She was incredible. "Good girl," you said as you held yourself within her.
As you pumped into the whore, watching her breasts bounce, her face lost in pleasure, you asked "You like that don't you
Mary?"
"Yes! Yes! Yes!" she screams back as your pumps seemed to bring her over the edge, her back arching, hands flailing as she crested the edge of her orgasm.
You then felt yourself losing yourself in her wanton moans and moments latter felt yourself cross the line as well. As you thrust home hard eventually cumming.
She bucked and thrashed under you, sharing your exultation, and the tow of you came together.
The pleasure roared through your body and then weirdly everything faded to blackness.
