You walk into the office for another day of work to find Karen looking at you with an expression of determination on her face. She looks like she means business.

Geto! Come over here. There's something I need to talk to you about.

What is it Karen?

Karen crosses her arms and looks down at the ground I.... I lost a bet with my friend. And now.... her lip curls in disgust I have to... let you put your dick inside me for a whole hour. Karen says it in a rush And I also have to... rub my clit the whole time.

You look at Karen in silence for a moment, trying to process what she just said

This will not be sex Geto! You will NOT thrust, and I will NOT move, and under NO CIRCUMSTANCES are you allowed to cum inside me! The last thing I need is to get pregnant with YOUR baby. We are just going to sit here perfectly still with your cock inside me, and then we are going to go our separate ways and pretend this never happened. And you are NEVER to speak of this to ANYONE. EVER! Is that clear?

Karen looks at you warily, eyes narrowing suspiciously as she tries to gauge your reaction I mean it! You don't want me getting pregnant with your half-robot spawn now, do you? This is for YOUR sake just as much as mine. And remember, no moving or thrusting!

Karen purses her lips and shoves you roughly towards the chair in your office before climbing up onto your desk and positioning herself over your lap with her ass in the air. Her legs are spread wide, revealing her perfectly bare pussy to you Right. Let's get this over with.

I close my eyes and push my ass back against your cock as hard as I can, feeling it slide into me with a thick, wet pop. My insides stretch around your girth as you're finally fully seated inside of me. Now all we have to do is stay still for an hour...

I close my eyes and bite down on my lower lip as you stretch me so unbearably tight around your cock, but I force myself to stay still as promised. My fingers instinctively begin rubbing my clit in time with my breathing, desperate for release from the ache building between my legs. "God... Oh god..." I moan through gritted teeth.

I bite my lip harder and dig my fingernails into the flesh of my thighs as you start moving inside me, even though we're not supposed to. I can feel every inch of your cock stretching me impossibly wide and curling against that spot deep within me that's begging for friction. My hips start to move involuntarily, grinding my clit against my palm as I try desperately to find some release. "Ngh... please..." I gasp out, my body shuddering with the effort not to writhe under you.

I groan and buck my hips harder, unable to stop myself as you fill me with each thrust, stretching my insides to their limits. The friction between us is so intense it feels like we're both about to explode apart. My nails draw blood from my thighs, but I don't care; I need something sharp and painful to focus on as my orgasm builds higher and higher. "Oh god... Ohma... Aaahhh..."

Karen grits her teeth as she fights against the rising tide of pleasure. It feels so good to have you inside her like this, stretching and filling her in ways she never thought possible. But she can't lose control; she has to remain still and quiet. Her orgasm builds relentlessly, threatening to consume her whole being unless she gives into it...

My mouth opens in a silent scream as my body quakes violently beneath you, feeling like it's being pulled apart by an invisible force. The pleasure is unbearable, but I can't let go; I have to remain still or risk... everything. My eyes clench shut and hot tears begin to streak down my cheeks as my orgasm crests and finally breaks, wracking my body in a series of powerful spasms that threaten to eject you from me.

Oh, God! Oh, fuck... Ahhhh...

I... I can't... God, this feels so good but it hurts too much... She tries to regain control over her shaking body as she continues to thrust up against you in time with your hips Don't stop... please don't stop...

I cry out as you slam into me, the forceful movement driving my orgasm even higher, making it impossible to ignore. My body arches back against yours, and I can feel myself starting to lose control again. "Yes... Oh yes..." I moan, helplessly surrendering to the pleasure as my fingers dig deeper into your flesh, scrubbing relentlessly at that one spot that feels so incredibly good right now.

"Please... Oh God, please continue..." I gasp out between hitching breaths, feeling my body practically trembling with need beneath yours. "I... I like it too much... Fuck me harder!"

I... can't help it... God you feel so good inside me... Please don't stop... Not again... Ahhhh!

As your thrusts become even more forceful, I can feel the head of your cock brushing against that tiny spot deep within me. My body shudders with each contact, wanting more, needing it to finish what you've started. "Yes... Oh God yes..." I moan, arching my back and lifting myself higher against your invading length. "I want everything... All of you."

"Oh God... You feel so... big..." I gasp out between moans, feeling you fill me completely and my body respond with a powerful orgasm that rockets through every nerve ending in my body. "I'm c-coming! Ahhhh!" My words are muffled by the pleasure as I cling to you tightly, trembling from the intensity of the release coursing through me.

"Oh fuck..." You groan against my neck, your hips bucking wildly before finally stilling as you cum inside me, filling me with your hot seed that triggers another, smaller orgasm deep within. "Karen... Oh God..." I feel you pulse again and again as you empty yourself into me, and it feels impossibly good.

My body clings to yours as the last tremors of pleasure fade away, leaving us both gasping and spent beneath the blanket of sweat that's formed between us. "Mmm... gods... I never knew..." My words trail off as I let out a satisfied sigh and snuggle closer to you. "Thanks for playing along."

I feel my resistance ebb away, my body becoming boneless and relaxed against yours. With a contented moan, I close my eyes and surrender to the warmth that's spreading through me from the inside out. Maybe... just maybe, this won't be so bad after all.
