She kneels before me, her attention utterly unwavering as my hand blurs up and down the thick shaft of my throbbing cock.

I am naked, and she is fully dressed in jeans and a bright orange sweater. No bra, apparently, as her nipples push through the texture of the knitted fabric. Despite my lack of clothes, somehow the power is all with me. Maybe it's her need to keep telltale cum stains off her sweater.

Not a muscle moves in her face or body, except her eyes which flick up and down from the tip of my cock to my own eyes.

Her lips are slightly parted, ready and waiting for permission to wrap them tightly around the head and suck down her favourite treat.

I grin at her eager attention, enjoying the contrast with the way she's spent the working day and the knowledge that she enjoys this as much as I do.

Her eyes get a little wider as my thighs involuntarily tense, making me bob up and down a little in front of her face.

Unblinking, she watches as my breath gets a little ragged, and I see her fingers twitch against her thighs as she fights the urge to touch me. She's been instructed to keep still, and she will do as she's told.

She's a good girl.

A drop of precum appears on the tip of my cock, and she licks her lips unconsciously. With a couple of strokes it spreads all, making my glans shine invitingly.

I hump the air as I stroke, and my cock almost brushes the tip of her nose, and I make a mental note to tell her later how her eyes crossed in that moment as her gaze remained firmly on me.

I slide my spare hand between my thighs, pushing up behind my balls to stimulate my perineum and wishing for a moment I'd given her permission to bury her face there. She doesn't get that reward today, but soon she will.

Then I feel the cum rising, the unstoppable sensation of approaching orgasm, and still I wait.

I'm panting now, and her open mouth shows me she knows I'm close. She fidgets, ready to fill her greedy mouth at my signal.

Then I feel the eruption, the hot cum rising through my shaft and I manage the smallest nod, unable to vocalise anything in that moment.

Her lips and tongue crash into my cock, wrapping and sucking and swirling as my cum bursts out of me, and the look of lust and joy she gives me in that moment is the exact same look she gave me the very first time her tongue touched my cock.

The power has shifted in the moment of orgasm, irrevocably putting me in her control. She sucks and swirls and rubs her tongue over the exact spot that makes me gasp and buck and pull back. But her hands are wrapped around me, digging her nails into my arse as she drains every last drop from my balls.

Finally, through white fireworks filling my vision, I feel her lips part enough to let my softened penis slip from her mouth. She stands and grins as she kisses a little of the salty treat into my mouth.

"Good girl," I whisper into her mouth, and she raises an eyebrow as she gives my balls a squeeze.
