Ask her if she's wet enough

You pause from your ministrations of pleasure and look up at her blissed-out face. She tries to roll her hips against your hand but you pull your hand away.

"What??" She finally says, "why did you stop?"

"Well," you respond, "weren't we just doing this to get you wet?"

"Oh, right?" Sophie looks a little confused as she tries to pull herself together. Her hand, seemingly involuntarily, drops down to her crotch and she absently strokes herself over her panties. She's so turned on she's only partially present to the world.

Diana interjects, resting her hand lightly on her students shoulder. "Sophie?" She says, looking down at the masturbating redhead, "You were going to show the class what it's like to touch Joe's penis with natural lubrication."

"Oh my god!" Sophie says, suddenly realizing what she's doing, "I'm so sorry, teacher, I just- I forgot where I was!"

"It's ok!" Diana laughs gently, "Let's just get back on track, ok?"

"Of course! Sorry Joe! Your idea worked, I'm totally wet. It just worked too well, I guess!

"No problem," you shrug.

Blushing bright ride with embarrassment now in addition to arousal, Sophie looks at you and your waiting cock.

"Ok..." she says to yourself, "'milk' it..."

She reaches out and softly takes your cock, giving it a few gentle, dry tugs. The sweet pleasure of her touch almost brings a moan out of you.

Then, she lets her hand return to her panties, this time slipping it underneath, touching her wet pussy. You hear a wet noise as she slides her fingers into her vagina, and her eyes flutter closed. For several long moments you watch as she plunges her fingers in and out of her pussy, making a few quiet, cute gasps, and then her eyes pop open again as, through her lust, she remembers what she's doing.

"Right..." she says, taking her wet hand out of her panties. She wraps her hand around your cockhead and begins 'milking' it like Diana had said before. It feels about a thousand times better than it did dry, and you feel yourself pushing gently against her hand. She seems to be enjoying herself more, she matches your pressure with her own, firmly gripping your cock as she milks it up the shaft.

"Faster," you moan, and she starts pumping your shaft as well as working the head. Her other hand goes back to her pussy to collect more cum, although it stays there for an awfully long time, eliciting more gasps from her before returning to get your dick even wetter.

You can feel yourself getting closer to orgasm, but you feel like you want something more. What is it?
