When the principal at Kerrigan Junior High School told you that you would be shadowing Justin Timberlake's class as part of your student teaching, you immediately felt at ease. You and Justin had been friends ever since you both had Professor Durham for Intro to Teaching back in college. He had just switched to a health education major from music education and even though he was a junior and you were a freshman, you hit it off immediately, bonding over your mutual love for teaching and your mutual hate for Professor Durham.

Justin was the whole package in your eyes: smart, confident, funny, caring, and passionate about teaching (not to mention ridiculously good looking). So of course you couldn't help but have a crush on him. But if you thought that he viewed his relationship with you as that of a mentor or friend, not boyfriend and girlfriend material, back in college, you were positive of that now. Because as far as you could tell, you were the only one who felt uncomfortable at the moment.

It was your luck that you would schedule your student teaching time with him right in the middle of sex ed. Watching Justin explain all the things you wanted to do with him (minus contracting the STDs, of course) while he barely batted an eyelash was quite unnerving.

On this particular day, Justin had decided that instead of continuing the lesson he wanted to pause and give the students a chance to ask any questions they might have. When he proposed this to the class, the students groaned.

"How embarrassing!" One kid exclaimed.

"I'm not saying anything out loud," said another.

Justin rolled his eyes at the class. "Do you really think I would make you guys do that? I'm gonna leave the room and let you write down any questions you have anonymously on a slip of paper. Ms. Summers is going to pass around a basket for you to put them in, and then I'll come back in and answer them." Your heart fluttered as it always did when he said called you by your teacher name but you did your best to suppress any reaction and smiled reassuringly at the class.

It was a testament to Justin's ability to put the students at ease that ten minutes later the basket you had passed around was full of questions from almost every student.

You stuck your head out the classroom door, looking up and down the hallway for Justin. You spotted him about twenty feet to your right, reading a bulletin board next to a row of lockers. God, he was gorgeous from head to toe: hair just long enough to start curling a bit, slight stubble on his face, a white button down shirt and black tie with the sleeves rolled up so you could see the veins bulging on his crossed arms, black jeans, and crisp white Nikes. You shook your head to clear it of the inappropriate thoughts that began to form and called his name to get his attention.

He turned to face you. "All done?" He asked with a smile.

"Yep," you said with a nod, your eyelids fluttering a bit as he passed you, his clean scent filling your senses.

"Okey doke, let's see what we've got here," Justin said to the class, shaking the basket like it was full of raffle tickets, not adolescent questions about sex. He pulled out the first slip of paper and unfolded it, scanning it quickly before reading it to the class. "Is it illegal to have sex before you get married?"

A few students laughed nervously, but Justin continued. "Well, that's a good first question. It is not illegal to have sex outside of marriage. Many people choose to wait until after they are married to start having sex for a number of reasons, which we actually will be talking about next time. But while it is an honorable choice to wait until you are married, many people do not and there is nothing wrong with that as long as they are involved in a healthy, loving relationship and they are both old enough and mature enough to make the decision to protect themselves."

Justin tossed the question into the trash and pulled another slip from the basket. He looked at the paper and shook his head, grinning. "I'm sorry, but 459-0521 looks more like a phone number than a question to me."

A few of the girls giggled and blushed and a boy in the front row took his cell phone out and asked if Justin could repeat the number.

"No, Brady, I will not be playing matchmaker today. That's in next week's lesson plan," he responded, tearing up the paper and throwing it away before grabbing another one. He read it over and an odd, unreadable expression crossed his face before he read it out loud. "What kinds of things do people fantasize about when they masturbate? Is it okay to fantasize about things you wouldn't do in real life?"

He took a deep breath before answering. "To answer the second question, it is perfectly okay to imagine yourself doing sexual things you wouldn't normally do in real life, as long as they aren't unhealthy fantasies like having sex with a child or an animal or something."

A few of the kids made gagging noises.

Justin chuckled. "I know, but there are some strange people out there. As to what the fantasies are about, everyone has different ideas of what is sexy and what arouses them." You wondered what Justin fantasized about. The thought of him all alone, aroused and touching himself, made you blush. You stared down at your shoes to rid yourself of the pictures swimming through your brain.

As if right on cue, someone's cell phone went off.

I wanna, li-li-li-lick you from yo' head down to yo' toes

And I wanna, move from the bed down to the, down to the, to the flo'

Then I wanna, ahh ahh, you make it so good, I don't wanna leave

But I gotta kn-kn-kn-know what-what's your fan-ta-ta-sy?

"Brady!" Justin said sternly, though he couldn't help but smirk as he headed towards the boy's desk. "I'll pretend I'm not terrified that you have that song as your ringtone," he said, shaking his head. As he took the phone from the boy and headed towards his own desk, an idea suddenly popped into your brain. It was risky, but you were tired of playing it safe. While Justin locked Brady's cell phone in his desk drawer, you quickly scribbled out a question of your own and shoved it towards the bottom of the basket, hoping none of the students had seen you.

By the time Justin had explained to Brady that his mother would have to come pick his cell phone up for him, the rest of the class had lost interest in the lesson and began discussions of their own. Justin sighed as he looked at the clock. Realizing there was only five minutes before the final bell of the day rang, he decided to let the students talk.

He motioned for you to join him at his desk. You brought the basket with you, placing it in front of him. He absentmindedly took a slip of paper from it and unfolded it as he said to you, "Kids these days." You wanted to laugh with him, but your heart was pounding with nervousness. He flipped through the rest of the questions and you watched over his shoulder until you realized yours was the last one left.

The dismissal bell rang just as he went to pick it up. Justin stood and headed to the door to say goodbye to his students as they exited the classroom. You watched Brady approach him after all of the other students had left.

"Mr. Timberlake?"

"Yes?"

"I'm sorry I had my cell phone on."

Justin smiled at him. "It's okay, but your mom still has to come pick it up."

"She doesn't get off of work until 5:00. Will you still be here?"

A look crossed Justin's face that clearly said he would rather head home early and get a head-start on his weekend, but he quickly replaced it with another smile. "Sure."

Brady returned the smile, wished Justin a good weekend, and joined the masses in the hallway scrambling to get out of school.

Justin sighed as he closed the door behind him to dull some of the noise. He walked among the students' desks, straightening the rows and throwing away loose papers. You sat at his desk, silently, unsure of what you were supposed to do and sure your plan had failed.

"Now I've got that friggin' song stuck in my head," Justin said, startling you.

"What song?"

I wanna get you in the Georgia Dome on the fifty yard line

While the Dirty Birds kick it for t'ree

And if you like in the club we can do it

In the DJ booth or in the back of the VIP

He continued straightening up the classroom as he imitated Ludacris and you couldn't help but giggle as he danced between the desks.

Whipped cream with cherries and strawberries on top, lick it don't stop

Keep the door locked, don't knock while the boat rock

We go-bots and robots so they gotta wait 'til the show stop

Or how 'bout on the beach with black sand

He approached his desk and you blushed as the lyrics got dirtier.

Lick up your thigh then call me Pac Man

Table top or just give me a lap dance

The Rock to the Park, to the Point, to the Flatlands

That man Ludacris, woo

He took the basket from his desk, your paper still in it and turned it over the trashcan to empty it. The paper fluttered to the ground, just missing the trash. He leaned down to retrieve it and your heartbeat sped up.

In the public bathroom or in the back of a classroom…

He stopped mid-verse and slowly stood up, his eyes glued to the slip of paper in his hands. You didn't need to see it to know what it said.

So, JT, what's your fantasy?

He had to know who had written it. None of his students would call him JT; it was your nickname for him back in college.

His eyes slid from the paper to you, the unreadable expression crossing his face again.

"Why, Ms. Summers, is this your handwriting?" He asked. As if you weren't already completely turned on, you felt your whole body flush at the husky tone of his voice.

"Yes," you whispered breathlessly as he leaned in towards you until your faces were inches apart.

He looked down at the paper again before tracing your body from the ground up, eyes stopping at your lips. "Do you really wanna know?"

"Know what?" You asked.

"What my fantasy is?"

Unable to speak, you nodded dumbly.

He leaned in further, his lips barely brushing yours. "Lock the door," he whispered against you before pulling back abruptly and handing you the set of keys he kept in his pocket.

Speechless and shocked and turned on all at the same time, you stood up and crossed the classroom to lock the door. When you turned around to return the keys to him, you nearly jumped out of your skin. Justin was right behind you, his hands against the door on either side of your body, and he leaned in to kiss you as soon as you were facing him.

The keys dropped to the floor as he moved his mouth against yours. It was just what you imagined and so much more. His lips were soft and perfect and he knew just how to use them.

You moaned when he traced your lips with his tongue and he pulled back. "We've gotta keep this quiet, babygirl," he whispered against you and it took everything in your power not to moan at the fact that he just called you "babygirl." But before you could make a sound his lips were back on yours, his tongue gently probing your mouth.

"Fuck, you taste good," he whispered when he pulled back again. This time, he brought one of his hands down your back, gripping your ass for a moment before lifting your thigh and wrapping your leg around his waist. Your other leg followed and you both gasped when your warm center pressed against his hardening cock.

He bit his lip and moved his hips against yours a bit to get a little friction before bracing himself against the door and kissing you again. You cupped the back of his head, hands lightly tugging on the curls at the base of his neck. One of his hands gripped your ass, holding your body against him, and the other trailed around your hip, beneath your white button up shirt and up your stomach, running a finger along the bottom edge of your lacy bra.

"Is this okay?" He asked shyly.

You nodded impatiently, grinding your crotch against his. He hissed at the sensation and his hand slipped up to cup your breast through your bra. You arched into his touch as his hand softly molded your flesh. As he kissed you again, he brought his hand behind you to undo your bra. He lowered you to the ground for a moment and began unbuttoning your shirt. You slipped that and your bra off your shoulders. Justin bit his lip as your breasts were revealed to him.

A noise in the hallway startled you both, reminding you that time was something you did not have a lot of.

"Shit, I wish we didn't have to rush this," Justin whispered, leaning in and cupping your bare breasts in his hands.

You looked between you and eyed the bulge in his pants. Suddenly, you had an idea. You slid to your knees, trapping yourself between the door and his crotch. He sighed softly as you unzipped his pants and pulled his erection free from his boxers.

For a moment you stared at his cock. It was beautiful: long and thick, red and hard. Without warning you leaned in and enveloped the head in your mouth, licking your tongue up and down the slit, tasting pre come, before moving in to swirl it around the ridge of skin beneath the head. Justin yelped in surprise.

"What're you doing?" He managed to say, gently gripping your hair as you pulled back and licked up his shaft.

"Taking care of you," You whispered seductively against his heated flesh. "We can finish things between us later."

"Fuck," Justin mumbled as you reached with your hand to massage his balls. He gently tugged you back up his body. "I need you now," he whined.

You looked around desperately, knowing that having sex up against the door was very risky. Your eyes settled on the countertop that ran along the back of the classroom. You made your way briskly across the room, settling on top of the counter, spreading your legs and pulling your panties aside, revealing yourself to Justin.

"Shit," you heard him say as he made his way towards you. He stopped at his desk and fumbled around in the drawer until he found the box of condoms he was going to use for a demonstration next week.

"We don't need one; I'm on the pill and I'm clean," you said, spreading your legs wider.

"Are you sure?" Justin asked, hesitating. You nodded repeatedly until he dropped the box back into the drawer and shut it.

"Fuck, I need you so bad," he whispered breathlessly as he moved between your legs. You reached between you and gripped his cock, pressing the head against you intimately. He gasped as you rubbed it up and down your wet slit.

"C'mon," you moaned, trying to get him to enter you.

He pressed in slowly, giving your body time to adjust to him. When he was in all the way, he buried his head in your neck and you could hear him grinding his teeth and whimpering at the pleasure of your tightness around him.

You both looked between you as he pulled out until just the head of his cock was in you and you both gasped at the sight of his cock slick with your juices. He pushed back in quickly and pulled out again, establishing as steady rhythm.

On the next in-stroke, you grabbed his ass and pulled him into you deeper and he let out a primal groan.

"Shh," you whispered, pulling his head down so you could kiss him. He sped up as your tongues played with one another, your bodies rubbing sensually. One of Justin's hands cupped your breast, tugging lightly at your nipple while the other trailed down your stomach and in between your legs. He pulled out of you completely and dipped his finger in your wetness before re-entering you and rubbing your throbbing clit at the same time.

You gasped at the sensation, clenching around him. "Justin!" you cried breathlessly. He rubbed harder against your clit and you tightened around him again.

"Oh, I'm gonna…" he moaned.

"Yeah," you whimpered.

Justin pinched your clit and that's all it took for your body to grip his over and over again as wave after wave of pleasure overtook you. He silenced your cries with his mouth, only pulling back when the pleasure was too much for him to handle.

"Fuck!" He moaned and you felt him reach his peak, his cock throbbing as it shot out his come in thick, sticky waves. His head fell to your shoulder again and he placed gentle kisses along your collar bone as the final waves hit him and he began to soften inside you.

When you had both caught your breath, Justin reached for a box of tissues you hadn't realized were next to you, pulling out and handing you one to clean yourself off before taking one for himself.

Taking the tissue from you when you were done, he tossed it in the trash and leaned in to kiss you again. "Come home with me," he whispered against your lips.

You smiled. "I'd love to."

The next few moments were silent as you both got dressed and tried to make yourselves look like you hadn't just had mind-blowing sex.

"So what's yours?" Justin asked when you had both gotten resituated.

"Huh?"

"What's your fantasy?"

You smirked and leaned in to kiss him on the lips one more time. "Well, it's not exactly a fantasy anymore…"
