When in Rome...

"Uh... Ok."

How could he say no? Jessica was already stroking his cock as he stood there. There's no turning back at this point.

Jessica gave Ian another "fuck me" grin, and led him onto the stage by his cock. Once they got back up to the stage, she kissed him passionately and explained how the lesson would unfold.

"In order for me to get close to the microphone and stay in range, you will have bend me over this desk and fuck me from behind like a dirty slut. And don't hold back: I want to feel that cock filling me up over and over again."

Despite everything that had happened, Ian was taken aback by how sexually charged her language was.

"There's a second mic hanging from the ceiling. Once you're ready, you should move that over so you can talk into it. We use the mics so we can record all of our demonstrations: The students will get a transcript of what we say so they can study after class."

"Ok," Ian said, distracted by the situation. "Should do an introduction or set the scene or something?"

"Nah," Jessica said, "they know I like it hard and fast. Plus, there isn't a girl at this school who wouldn't jump on a dick as big as yours. One look at that throbbing cock was all they needed.

Ian needed to take a minute and contemplate that for a bit. After a few moments, Jessica pulled Ian back to attention by navigating his cockhead to her wet slit. As drops of girl-cum dripped onto Ian's hard cock, he instantly refocused on the task at hand. She moved to the microphone next to his ear whispered loudly enough for everyone to hear; "I need you to spin me around and fuck me from behind so hard that I scream so loud the whole school can hear me. I can't wait anymore, Mr. White. Do your job and fuck me."

He didn't really understand it, but somehow Ms. LaChaud's challenge got to Ian. Without any warning, he grabbed her, turned her around, and pressed her torso against the desk with his left hand. With his right, he eased the head of his cock into Jessica's hot, wet box. As he slid all the way in, Ms. LaChaud moaned with satisfaction.

"Mmmmmm. That's what a giant cock feels like. Give me more!"

While his opening move suggested he was going to be gentle at first, Ian was so horny and in need of release that he immediately grabbed Ms. LaChaud's hips and began pistoning in and out of her relentlessly. Ms. LaChaud squirmed, grinding her nipples into the desk and crying out.

"FUCK ME! FUCK ME! FUCK ME!" Jessica cried. "Give me that thick dick!"

Feeling his swinging balls tightening, Ian knew he was getting close so he slowed his pace a little. Jessica immediately responded by bucking back into his dick. Every back-thrust pushed back right up to slap Ian's balls.

Fwap, fwap, fwap. "Oh don't stop now, baby," Jessica cried out. Fwap, fwap, fwap."I love it when you plough me deep."

To retake control of the situation, Ian slapped her tight ass and lifted her left leg on the desk. Rather than picking up the pace, Ian pulled his cock all the way out of Jessica's tight twat and then pushed himself all the way in, causing the dark-haired professor to scream out.

"FUCK! That feels so good, daddy."

The daddy comment spurred Ian on: He started thrusting even harder and actually started talking.

"Your pussy is so tight, baby. Do you like it when I stretch your tight pussy with my daddy dick."

"I love your big dick, daddy," Jessica egged him on. "Keeping fuck me... Ohh! Just like that. More! More! MORE!"

By this point, Ian knew he was going blow his load: "I'm going to cum," he cried.

Jessica responded by breaking her own rule, spinning around and getting on her knees. "I want you to cum all over me, baby," Jessica said, jerking his cock rapidly. She was about to put Ian's head in her mouth when a huge load of cum surged out of it, plastering her face with hot, milky seed.

Jessica started licking around her lips to get a taste, not realizing that Ian had only just started cumming. Another wad shot directly into her open mouth, a third shot aimed down and coated her tits. Realizing she would have the chance to drink Ian's sweet spunk right from the source, Jessica clamped her mouth down on Ian's cock and sucked as hard as she could. Load after load poured out of Ian's cock and into Jessica's mouth: At first she could keep up, but eventually cum started spill out of the sides of her mouth, spilling more hot cum onto her tits, legs and the floor.

After she finished, Jessica leaned back and said, "You have the most delicious cock, Mr. White. Next time, we'll have to start with a nice, long blowjob." She winked and cleaned Ian's cock with one more slurp before getting up and turning to the class:

"See class," Jessica said in her most authoritative voice. "When you tell people what you want, most are happy to oblige... Especially when what you want is a fat dick and some tasty cum." Jessica turned back to Ian and gave him a sultry smile. Even though he had just cum buckets, Ian was already starting to get hard again.

"So professor White," Jessica asked coyly, "what should we do next?"
