She refuses him.

"N-No," Nat manages to gasp, collecting her thoughts. "N-no, th-thank you. I don't...want any cum right now."

"Oh." The boy positively deflates, looking both crushed and ever so slightly angry. Ms. Poundwell sighs.

"Well, that's her right, but I must say, it really isn't very fair of Miss Pierce. After all, it was her luscious little body that got you all hot and bothered in the first place! The least she could do would be to accept your cum." Nat blushes in embarrassment as Ms. Poundwell shakes her head scoldingly. "Tell you what: I'll deepthroat you real quick, how about that?"

"Oh! Uh, w-what? Are you sure that's...ok?"

"Of course!" Ms. Poundwell frowns. "Why would it not be?"

Frank scratches the back of his head, perplexed. "Well, you're a teacher..."

"Right, but this isn't high school, Frank. You are over 18, right?"

"Well, yeah."

"Good. Several someones would have lost their job otherwise," she says with a chuckle. "This is Bridge Year, Frank! And you're a grown up and I'm a grown up. Teachers aren't some untouchable, otherworldly entity here, especially the women wearing green neckbands. All you have to do is ask nicely."

As Nat watches, still locked into the stool, Ms. Poundwell drops to her knees in front of a startled-looking Frank. She runs her hands up and over the front of his khaki shorts. "Mmmmm. Feels like you've got a nice-sized cock in there. May I take it out and suck on it?"

"Um, um...yeah," Frank gulps, gasping slightly as he steadies himself against a desk. Ms. Poundwell purrs as she reaches up to unbutton and unzip his shorts, then pulls them and his boxers down in one easy motion. She laughs with delight as his already hard cock springs out.

"Well, this is just delicious! And so hard...don't worry, dear. I'm a professional sex educator, I can take care of this in no time. You just relax." Rising up onto her knees, the blonde teacher leans forward and takes Frank's five-inch cock fully into her mouth. The boy groans, knees buckling slightly as he clutches the desk and Ms. Poundwell closes her lips around the base of his shaft. Frank tilts his head back, eyes closing, as his teacher begins to industriously bob up and down on him.

Nat watches from her imprisoning perch, both incredulous and slightly turned on. Ms. Poundwell blows Frank erotically but with an almost industrial efficiency, slurping up and down on his shaft as he moans above her. She’s doing everything Nat’s seen other girls do for a boy, and been told to do herself - making eye contact, moaning slightly around the boy’s cock, occasionally reaching up to grope and massage her own tits through her green mini dress - but it’s almost as though these are staged. Like they’re algorithmically inserted bits from a repertoire, put in because they’re going to get the job done.

She doesn’t feel anything about this at all, Nat realizes somewhat wonderingly. It's like she's...she's not excited by his cock and she's also not afraid of his cum. She's just doing her job as fast as possible.

Even as she thinks this, fascinated, Frank makes a slightly strangled noise and his hips buck, attempting to lodge himself even more deeply in Ms. Poundwell's throat. The blonde teacher looks up at him from her position against his pelvis, smiling slightly, as he lets out a long groan. Nat can see his pelvic muscles twitch as he cums, but there's hardly any evidence of it otherwise - not a single white drop leaks from Ms. Poundwell's lips. As Frank finishes with a gasp, Ms. Poundwell sits back on her heels, opening her mouth to display an impressive collection of spunk to Frank and Natalie. She sits there unmoving for a few moments before Frank realizes what she's waiting for.

"Er, y-you...can swallow it if you want," he says uncertainly.

Ms. Poundwell closes her mouth, swallows once, cleanly, and smiles. "Thank you, Frank. Don't forget, it's always good to have clear, enthusiastic consent! Men's cum is important, a girl should wait for your command before swallowing it down. What if there was another girl you were saving it for or something?"

"Right," Frank says, blushing slightly as he tucks his dick back into his boxers and closes his shorts. "S-Sorry."

"No need to apologize! That's what this is for: learning." Ms. Poundwell stands fluidly. "Now, hurry on to your next class."

Frank nods. "Thanks, Ms. Poundwell," he says with a grateful smile.

As he turns and heads out the door, Ms. Poundwell turns to Natalie. "As for you," she says briskly, "I do hope you'll take the reading from All Holes at Heart seriously. You certainly aren't bound to fuck any boy who asks - but don't you go thinking you can just avoid cock entirely. You have an ethical responsibility to your peers. You're a fine piece of ass, and when you get a boy worked up like that, his spunk's going to end up somewhere. When your holes are part of the problem, your holes should be part of the solution!"

"Yes, Ms. Poundwell," Nat says, subdued. "Sorry."

"Don't fret, dear. You're learning too! Just think a little more carefully next time." Ms. Poundwell unbuckles Nat's ankles, then her wrists, and Nat sits up, rubbing them to get rid of the soreness from her long-held position. "Remember, when a guy asks you for a fuck, or to cum on you, or whatever, your first thought shouldn't be, 'Do I want this?' It should always be, 'How can I make him happy?'"

"Got it," Nat mutters as she pulls her clothes back on.

"I hope you enjoyed the show, at least. Here's a hall pass - the bell might ring before you get to your next class."

A minute later, Nat finally makes it out of the classroom and begins making her way toward her next destination...
