Agree

The doctor's eyes light up as your gruff voices responds, "Sure," followed by a short nod. Wasting no time, she strips off her lab coat, tossing it over the same chair that holds yours, and climbs up onto the table. You are given a direct view at her glistening, dark blue pussy nestled between her legs, your cock quickly springing to full attention, around six inches long. Her sizable thighs flex with effort as she bends her legs, lowering her body directly onto your extended erection.

You gasp as the tip of your foreign penis enters the warmth of her sex, sliding in easily due to what seems like an almost constant lubrication. The succubus is simply smiling down at you as she continues to lower herself, easily fitting your entire member within her body, coming to rest as if simply sitting on your groin. After several seconds in this position, her legs begin to move again, and she lifts herself up several inches, the walls of her pussy sliding along the length of your new penis.

She continues this up and down motion, steadily speeding up. Your gasps fill the room, each time surprising you at the deepness of your voice, and the doctor can't help but giggle every now and then at the astonished look on your face. The feeling of your cock against the walls of her pussy is unlike anything you've ever experienced, and so your will is short lived, as you feel an impending orgasm within minutes. Denaria looks down and winks at you, which is all the encouragement you need, and you feel as if you practically explode within her confines, strong spurts of cum shooting directly into her body. She presses down against you for the entirety of the orgasm, trapping your semen within her, and only when your shakes start to fade does she stand back up, stepping down from the table with a loud clacking sound, white drops starting to leak from between her legs.

"Thank you very much, dear, that was refreshing. Now, would you like to go back to normal?" There's at least a small measure of hesitation in your response, as you focus on the thought of the pleasure you just experienced, but you realize how foreign your current body feels, and do eventually respond with a short "Yes, please."

As if she can read your hesitation, the doctor leans over and flicks the tip of your cock, sending a few small drops of cum flying across the room. "You know dear, if you're attached to this, I can let you keep it."
