"Maybe a little"

This is too easy. You've already got Joy in the palm of your hand and she doesn't realize it. Not only that, she keeps volunteering information, as if she's looking for someone to spill her thoughts to.

"I mean..." she goes on "These old guys look at you in ways, and it's obvious they're never going to be with a pretty young girl again, and sometimes they find ways to touch you, accidentally or not so accidentally. Something about being lusted after like that is hard to resist."

You wonder, is the taste of your juices on her tongue making her horny even if she doesn't realize it? Listening to perfect little Joy admit to something this naughty is certainly making you horny, or rather hornier than you already were.

"Show me" You say. Joy looks at you quizzically. Either she doesn't know what you're suggesting, or she's waiting for you to confirm what you're suggesting. "Show me how you fantasize about them." Your pussy is already wet again.

"Well... I... um..." Joy looks around, as if she's looking for someone or something to excuse her from having to do this, even though she wants to.

"I assume you rub yourself." You smile. You try to be as gentle and kind as possible. You don't need to pressure her into anything. If she doesn't want to answer your question, she'll say so. If she does she'll say...

"Yes" She says with a smirk.

"Then show me." you say.

Joy bites her lip. "You want me to masturbate for you, for free pizza?"

"No." you answer. "I wanted you to answer that question for free pizza. I want you to masturbate for me because you want to."

Joy takes a deep breath. She doesn't need to think if she wants to. Her hand is already finding it's way into her scrub pants. She leans against a nearby counter, spreading her legs slightly, closing her eyes.

You can't see exactly what her hand is doing down in her pants. But you know the moment her finger finds her clit.

"Tell me what you fantasize the old guys doing." you prod.

"First, jerking their cocks at me." Joy takes a deep breath.

You're getting impossibly wet. "You'd prefer more than one?"

"....Yes" Joy is starting to breathe very heavily now.

"How many?" You want to slide your fingers down into your pants. But you hold off. You need to maintain control.

"As many... as possible... all of them...."

"And what do you do to them?" This is great, you think.

"Anything... Everything... They hold their cocks out for me to suck and lick and to... cover me in their cum..." Joy has turned out to be a total freak, and you're loving every moment of it.

"Do you get to taste all the cocks?" You try to suppress a giggle at this perfect girl, supplicating herself in front of you.

"Yes... even the ones... that were inside me..." Joy winces. She's already getting close. The thought of this must really do it for her. "And then...." she says. "And then...."

And then suddenly the sound of a door opening and a voice. "Joy? Are you in there? Joy I need you."

You jump up and try to cover up what's going on. You expect Joy to do the same, to pull her hand from her pants and get back to work. But she's too far gone. She just keeps rubbing. You realize she's going to be caught. No question.
