We can let Sophie rest.

"One of the other girls can do it," you say, "Sophie seems happy as she is."

"Very happy," she murmurs, splayed legs showing her soaking panties.

"Ok, then!" Diana claps her hands briskly, "Nice work getting Sophie lubricated, Joe! Girls, who would like to use Sophie's natural lubrication on Joe's penis? Grace?"

The blonde comes to the front of the room and sits near Sophie. Her hair is pulled neatly back in a ponytail and her larger breasts are covered in a button up white blouse. She looks very focused, yet she has the most beautiful face.

"Ok," she says, "will you sit next to Sophie?"

You pull a chair so you're knee to knee with the two of them. Your penis is only semi-hard right now, but it's perking up at being so close to these two sexy young women, one who is looking like the model of a cute, dedicated student, the other who is lounging in a post-orgasmic bliss.

"Sophie," Grace says, "Is it ok if I use my hand to get some of your...natural lubrication?"

"Sure," she says comfortably, eyes still shut.

Grace reaches over towards Sophie's panties, hand pausing to hover just a few inches from the soaked fabric. After just a moment of hesitation, Grace seems to relax into a decision. She slides her hand into Sophie's panties and you watch, jaw dropping open, as she _swirls _her hand around Sophie's pussy. You can literally hear the wet sounds of cum being pushed around.

"Mmmm, that's nice." Sophie says, widening her legs slightly.

Grace nods, still with a focused look on her face, and pulls hand out of Sophie's panties. It's visibly wet now; she did a good job harvesting the cum from Sophie's satisfied sex. After another brief moment of hesitation, she reaches and grabs your cock. You instantly feel yourself start to harden again, a process that triples in speed as she begins firmly pumping your cock, Sophie's cum making the movements smooth and intensely pleasurable.

She seems to know what she's doing- or maybe she's just a fast learner. She goes all the way down to your base, then follows it up to the very tip, squeezing just a little harder at the end. As you close your eyes and start thrusting into her hand, you can almost believe it's her pussy.

"You should use both hands," you tell her.

"Ok," She says, sliding her other hand into Sophie's panties. This time she spends a little longer swirling around, "There's not as much," she says, continuing to swirl.

You almost don't care, as you thrust your hard cock into her soft, glistening hand. But there's something intensely sexy about watching the shape of her other hand move around under Sophie's panties. And as she quests for more moisture, you can actually see her hand dip in and disappear slightly as she pushes gently into Sophie's vagina.

Now Sophie moans again, quietly but surely, her legs widening even more. "Oh my, that's nice." You feel Grace's grip tighten slightly around your shaft as she hears Sophie's words. Your pleasure increases with her touch, and you start to feel your excitement build. You thrust faster.

She starts exploring Sophie's vag more thoroughly, and more quickly. It looks like she's trying to get Sophie to lubricate further by turning her on. She's a quick learner for sure. Sophie is starting to make little gasps and gyrations with her hips as Grace works her, and sure enough, the wet sounds are starting to come back.

You're sure you'll come first, but somehow you make it- Sophie's moans turn to gasping screams as she grinds her pussy against Grace's relentless, determined hand, fingers still thrusting in and out as she grabs for more cum. You watch Sophie's hard nipples as her breasts heave with her scream, and almost don't notice Grace's swift movement.

Because as soon as Sophie finishes cumming, Grace swiftly pulls her hand out and bring it, soaking and dripping wet, to do double duty on your cock. She starts pumping you in earnest and you grip the edge of your chair as your balls clench- you thrust into her and start blasting your load; it covers her hands, sprays your pleasure up onto her blouse, onto Sophie's legs. You're awash in ecstasy and the two girls are awash in your cum.

Grace doesn't stop until your spent. Then she looks down at her sopping wet hands in satisfaction and says, "I did it!"

Fuck yeah she did.
