I inch higher, and when I make contact with her clit through her lace underwear, she presses her face into my shoulder, muffling a moan.
I turn my hand, shifting her underwear aside and rolling her clit between my fingers. She's so wet, and I grin, knowing the hours I spent building up her arousal has her exactly where I want her.
I work her up slowly, stopping each time a moan slips from her lips. I have no intention of letting her come yet. She responded so well to the edging I'd given her that first night that I want to see just how far I can push her before she falls apart.
When the cab turns into my street, I pull my hand away, and she whimpers. Chuckling, I brush my lips over her temple, before leaning forward to pay the driver once he pulls into my driveway.
She grips my fingers when I help her out of the car. Her eyes are glazed with lust, and as soon as I close the front door behind her, I turn her body so that her chest is pressed against the door, sliding my hands up her thighs to grip the band of her underwear.
"Do you want to come, Imogen?" I ask, dragging them down her legs.
"Yes," she whispers, a little sob escaping.
"How badly do you want to come?" I kneel behind her, continuing to drag the lacy fabric down her legs, inch by inch.
"So badly. Please," she begs.
I help her step out of the panties, tossing them aside before returning to stand behind her.
"I like it when you beg, Imogen." I pull her hips back slightly, then glide my hand over her arse. "If you beg enough, maybe I'll let you come."
She moans when I smack her arse. I'd suspected she'd be into spanking, and a smile ghosts across my lips when I do it again, harder.
"Fuck, please, Cam," she sobs.
I push two fingers deep into her pussy, feeling her tighten around them as she gasps.
"Yes," she whispers, her forehead pressed against the door as she pushes her hips back further, trying to fuck my fingers.
I grip her hip, forcing her to remain still. "Remember, Imogen. I control when you come."
Another sob escapes her. "Please."
I add a third finger as I fuck her lazily with my hand. She moans, doing her best to stay still, her body shaking with the effort.
"We're just getting started. I plan to make this last for hours."
She's so wet that I can hear the sucking sounds while I drive my fingers in and out, watching her pant, her chest heaving.
"Please, Cam. I need to come."
I wrench my hand away, and she lets out a strangled cry, glaring at me over her shoulder. I smirk before wrenching her around to face me. Dropping to my knees in front of her, I throw her leg over my shoulder and swipe my tongue through her pussy, before clasping her clit between my teeth.
"Fuck!" Her head hits the door as she throws it back.
I push my fingers back inside her as I suck on her clit, continuing the slow, steady pace. When I feel her start to quiver, I pull away again, looking up to find her panting as she narrows her eyes.
"You're fucking evil," she says.
I grin. "Yes, I am." Then I drop the grin. "And it's 'you're fucking evil, sir", remember?"
Her eyes flash as arousal rips through her. When her breathing starts to even out again, I suck her clit between my lips again, swirling my tongue over the sensitive bundle of nerves.
She moans again, tipping her head back once more. Each time she's close to climaxing, I pull away.
"Please. Please. Sir. Please let me come," she pleads, tears of frustration shining in her eyes.
Deciding the torture has gone on long enough, I pick up the pace with my hand and suck hard on her clit.
