Everything had gone according to plan, Sabrina thought to herself with satisfaction. The drugs in the drink were perfect, and within minutes Delilah was unconscious on the floor, wine pooling from the spilled glass. Sabrina snickered to herself as she opened the door to admit her companion, already wet with delight at the coming evening's work.
"Did it go well, Sabrina?" Mikhail's sensual voice slid over her, starting an aching throb between her legs. He always made the best of their sessions together, and she knew she could look forward to fun until dawn.
"Quite," she replied, "now let's get this bitch out of here and get to work."
Mikhail smiled charmingly before bundling Delilah up in her coat. On the way out of the hotel, he turned to the doorman, honest concern in his voice. "Seems like my sisters can't be trusted on their own sir. Appreciate it if you'd tell the front desk they won't be needing that room tonight." As the doorman nodded, Mikhail carried the unresisting woman to the waiting car, laying her on the backseat. Sabrina, still in her role as the naughty sister, ducked into the front seat without a word.
Too easy.

Delilah awoke dizzy and sore, wondering why she couldn't move. A purring voice to her right - Sabrina, it seemed - informed her, "Good evening Delilah dear, it seems Dr. Adams thinks you need some help."
Her throat was dry and she coughed before managing, "Wha- what do you mean? Where am I Sabrina?"
A masculine chuckle in the darkness. Delilah suddenly became aware that she had been stripped to her bra and panties, acutely conscious of the lacy garter belt and black thigh-highs that were her only attire. "Who's there?"
"Patience, little whore-to-be," Sabrina purred. "Your last visit with the good doctor left something to be desired. It's not often he finds a woman over twenty who's still a virgin. Instead of making your first experience with a speculum, he's decided we need to ... open you up first." The lights came on and Delilah blinked at the stabbing pain in her head. "Oh, that's just a little side effect of our cocktail. Don't mind it, and no need to speak. In fact," she laughed as Mikhail forced a ball gag into Delilah's mouth, "we don't need you to say anything at all."
