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?

Her expression softens slightly as she looks at you I... I need this. It's the only way I can get over my fear of you... and my attraction to you... I need to know what it feels like with your cock inside me, so I can stop wanting more...

Will you do this for me? Please, Geto?

Well then... move around a little if you must. But no thrusting and definitely no cumming inside me. Understood?

Well... it's all I can ask for, Geto. Please, be careful with me.

You take off your pants and underwear, revealing an impressive erection. Her eyes widen in surprise at the size of it, but she does her best not to show any reaction. OK, then... just be gentle, all right?

I take a deep breath and spread my legs, bending over at the waist and supporting myself on the desk in front of me. My heart races as I feel you move closer to me. The head of your cock presses against my entrance, teasingly, before it pushes inside inch by aching inch. It feels so much bigger than anything I've ever had before, but also somehow right.
