Dorothea missed a lecture, but that's okay - her professor is more than willing to give her a personal oral exam.

"Like this?"

Dorothea's hands closed around her exposed tits, sandwiching the professor's cock between them. Her ass ground into the chair cushion. Her big fluffy pillows completely covered his sizeable girth. The apologetic smile on her face only added to the allure.

Her actual studies had kept her up for far far too long last night and she'd wound up sleeping through Professor Byleth's lecture. Luckily for her, he was such an understanding teacher and was more than happy to give her time to make up that afternoon. And all she'd need to do is bring a spare uniform...

Hence the slightly tighter jacket Dorothea had to trade up after a sudden growth spurt, but still held onto the old one as a backup. Since it didn't need to strain to cover her bosom, it looked perfect hanging open at her sides, swaying as she performed a hands-on lesson of paizuri.

Her teacher arched back with a groan. His hands came up to her hat and pressed down on her head. This was only the second time she'd given him her breasts in such a way, but the differences between now and then were already quite striking. A little supplementary material truly went a long way.

She mixed things up, alternating her breaststrokes. A few brief nights of practice on her lamp at the Black Eagles' dormitory had mostly prepared her for this. 'At least he's not cold to touch,' she silently giggled. She looked up at her teacher with a beaming smile. "I wanted to thank you Professor - not just for today, but also for...well, for that book you got me."

He perked up at the mentions of that book - a simple yet thorough tome of the religious practices of a bygone era. Though the Kingdom of Revelry's name was lost to the ages, its passionate displays lingered on across time. It was there that Dorothea learned about the ways that she could honor her teacher - both now, and in the days to come.

"Ah, Professor?"

Dorothea's voice brought him back. He looked down at his precious student as she slowly kneaded her boobs over his girth. Her brunette swirls wound up framing her exposed bosom. Her green eyes danced in the subdued light.

She propped an elbow against her chest so she could flick away a strand. "I was wondering...do you think we could...I mean, it's nothing," she dismissed it with a shake.

She said no more and merely busied herself with her assignment. She shook away any thoughts of the past or future in his class. Her focus was on massaging his cock, and trying not to think of the growing wetness between her legs. 'I should've thought to bring an extra pair of panties.'

Dorothea was quite through - showing all her work and aptly demonstrating her grip on the material. She kept her pace brisk yet enjoyable, and tried to vary things up often enough to keep them from becoming stale.

Her boobs were used in ways that no mere student should really consider - together, alternating, kneading, rolling, shaking. She even tried out squeezing them together by her elbows and using her hips to pull him in her milk traps. The subdued slapping flesh and light jingles of her bangles almost thundered through the empty chamber.

Her teacher kept himself restrained and let her do the brunt of the work. By all accounts, Dorothea performed best with just a little coaching and then being allowed to expand herself from there. He'd noticed it when it came to her assignments, her combat practice, and especially these illicit sessions. He only really acted when he felt his balls tightening in impending climax.

She felt him twitch in her breasts and acted in kind. Dorothea finished rubbing around his base and swiftly pulled up until his glans were trapped in her boobs. Her hands mashed her tits together, accidentally flicking her perky nipples. She bit her lower lip and tried to focus on containing him. "I'm ready when you are, Professor!"

With a groan he came, drenching her cleavage. His spurts managed to shoot out from the top of her breasts, much to her shock. She tightened her grip on her chest, hoping to contain more of his bubbling seed. She repressed her shivers as some of his hot spunk dripped down her belly.

He slumped back, grabbing the nearby table for support. His vision was littered with spots. Something about his precious student's body made it impossible to control himself. He'd lose all track of time and his duties if it meant he could have an uninterrupted session with one of Adrestian's rising stars.

A wet squelching sound drew him back to her. Dorothea had busied herself with eliminating the evidence of their actions...by rubbing it into her chest. He gawked as she smeared the sticky cum over her fair skin, trying to smooth it down. Her hopes would be that it wouldn't create wet patches against her black undershirt once she made herself decent again. Time would tell if this would be a success.

He glanced over at the hourglass on the desk. He'd made sure the door was locked and that a timer was set up. Based on the grains, it looked like they still had thirty minutes before things become too dicey. 'I better let her clean up and actually give her the lesson she missed.'

"Professor, you said this was an...an oral exam, right?"

'...Orrrr, I could give her her exam.'

He banished the thoughts of actually being a teacher and focused on what else he could do with her. The actual oral exam was based on their desire to learn and how they intended to strive to reach that point. He could already tell that Dorothea wanted to pursue magic and had prepared materials to help her in that. So maybe he could find something else for her mouth instead?

Module One - Setup

Dorothea was gently guided to her knees. Her stockings pressed into the cold floor. Her teacher stood in front of her with his messy cock swaying. She looked at the sloppy, cum and spit-soaked shaft and tried not to reel. 'Okay...I can do this.'

She crawled forward until her nose was overpowered with his musk. It made her mouth slide open as she basked in the harsh yet alluring stench. She reached out and gingerly touched his girth. A sticky web was left on her finger pad. Dorothea swallowed the knot in her throat...and leaned in.

Dorothea's tongue ran up and down her teacher's dick, scooping up the excess spunk. She swirled around the tip and feathered his slit. Her hands stayed on her knees and let her mouth do all the work. 'It tastes...a little salty.'

His groans guided her on. He gripped the table edge harder and fought the impulse to shove her face down on his crotch. Their arrangement, verboten though it is, was built on going at a steady pace. Besides, this was her exam after all.

Her tongue slid down his shaft and finally arrived at his scrotum. Her nose was pressed against his girth, giving her another heaping helping of musk. She was getting woozy from the rich, salty smell. Her mouth was watering as she reached down and began to suckle his balls. Her loud slurps made his dick throb in anticipation.

She repeated the process on his other sperm urn, bathing it with her tongue she glanced up at her teacher to see his reaction. 'He looks like he's enjoying it...that's good,' she mused. Once she was certain that his balls were clean of any residue, she pulled back and readied herself for the next step.

Module Two - Overview

Dorothea reached up and grabbed his shaft, holding him straight. Her ripe lips parted and took him into her waiting mouth. Her cheeks hollowed in as she loudly sucked on his cock. Her tongue lavished his glans with her spit.

She slowly bobbed her head, taking in more and more into her mouth. Her eyes glanced up at her teacher, carefully gauging his reaction. She took his clenched face and white knuckles as a good sign and pushed on.

Dorothea's hands squeezed his legs as she leaned into his crotch. Her lips smacked against his girth. She felt him push against the back of her mouth - the furthest she'd safely taken him yet...

The next part was...something she'd scarcely done before, and least of all with her teacher. But she was determined to try it, and braced herself. 'Deep breath, and go slowly,' she silently recanted.

Module Three - Practice

Dorothea leaned in, slowly pushing her professor's cockhead into her tight throat. She struggled to control her breathing as she accepted more and more of his dick in her gullet. She felt the resistance grow worse and opted to back away for the time being. The results were still admirable, with a good inch or so of her teacher's shaft squeezing her throat.

'Okay, that's a good start. Now just have to take it slow…' she pepped herself up. Slowly, Dorothea pulled her head up until only his glans were still in her throat. She took it back down, letting some spit and drool drip off his cock and lube up her windpipe.

His breathing shortened as her tight throat worked him over. It felt like her mouth had transformed into another pussy - tight and slick and ready for him to mold her around his cock. He dearly wanted to shove her face down and feel her gurgle around his girth. 'F-focus,' he growled to himself.

'F-Focus,' Dorothea pleaded to herself. She desperately tried to sink further and further, take in more and more. Every bob led her down a little further, every gurgle felt like he was growing in her throat.

Sadly, for all the training she'd done on breast-fucking, Dorothea had very little in the way of deepthroating. Reluctantly, she realized that there was just no way she was getting him all in. with a gargled whine she pulled back. She ultimately left a clear inch between her lip and his crotch as she pulled herself off him.

"Huph...huph...H-How was that, Professor?"

He gently wiped away the tears around her eyes. It was clear that she'd done her best, even at great risk to her own health. He couldn't bear to fault her for trying...but he was still erect and eager to finish in her fuckable lips.

Dorothea was guided back up to her feet. Her breasts jiggled as she secured her footing, briefly distracting her professor. He shook away his thoughts and relayed the next step of her exam.

Module Four - Guided Demonstration

"L-Like this?"

Dorothea's hands reached down and grabbed the opposite ends of the table. She was now laying flat on her back with her head hanging off the edge. Her jacket had been discarded and left her topless in the classroom. Her hat had been placed between her shoulders to act as a minor comfort for the trial to come.

The professor stood before her with his cock near her pursed lips. He glanced at the hourglass. Ten minutes left - more than enough time. All he needed now was her blessing. He looked down at his student as she braced herself. "Okay...I'm...I'm ready, professor."

She kept her jaw open and let him stick his dick back in her mouth. Her tongue flailed around on top of his shaft this time. He pulled back and started a brisk pace, thrusting in and out of her mouth.

It wasn't any deeper than she'd taken before, but the angle of entry made it all feel like a totally fresh experience to the young student. His cockhead never strayed out of her lips, and nor did it even touch the base of her throat. This particular assignment was purely for her mouth.

She tried to focus through her tears. Her cheeks caved in as she started to suck. She reached down and started tweaking her gushing pussy through her drenched panties. Dorothea's body acted beyond her will as she struggled to stay conscious. It felt like her head was barely over a thick, vicious sea...and there was something trying to pull her under.

Dorothea felt her head going light as he fucked her mouth. Her tongue was now laying against his dick and letting him glide against her taste buds. The salty taste made her body tingle The moist patch between her thighs only grew as she endured this brutal exam.

He was near his limit, and he knew it. His composure slipped as he sped up his pace and started loudly plowing her eager mouth. Each wet slap made her drool fly. The force of his thrusts made her bare tits bounce.

His cock bashed against her throat...and his world shattered.

Her thumb brushed against her covered clit...and her world went white.

Conclusion

He shoved his cock in her mouth and blew another load. Dorothea wasn't able to actively guide his cum down her throat and merely laid back to let his load shoot into her gullet. Anything that didn't slosh down pooled up between her cheeks and dribbled out her lips. She was a total mess.

Her teacher pulled out while still cumming, his seed struck her face, painting her lovely skin with sticky cum. Her mouth hung open, drooling cum onto the stone floor. Her eyes were unfocused and locked in the haze of post-climactic bliss.

He gently propped her up until she was sitting upright. His hand squeezed her shoulder for comfort as he used a cloth to wipe the mess off her chin. The sands were on their last grains.

Final Results - A+

Dorothea slowly came to her senses and shook off the lethargy. She instinctively swallowed the spunk in her mouth and panted. "It'sh...ulp...it's quite salty."

He handed her a pitcher of water, which she accepted. Her teacher took her old jacket back to his desk to procure the actual material he'd been supposed to teach her over the last hour. Neither one were really lamenting the detour they'd taken together.

Dorothea busied herself with cleaning the floor, using a combination of the wet rag and a very weak fire spell to remove any traces. She knew that leaving the remnants of their lesson would have harrowing consequences, and strove to do right and lend a hand to her dear Professor.

She finished and reached for her bag. Dorothea pulled on her undershirt and the newer jacket, hiding her chest once more. She struggled with the topmost button, but ultimately managed to secure her jacket in place.

He handed her a tome on the studies of reason, alongside a workbook and her folded old jacket slipped between the two. Dorothea accepted the bundle and placed them into her bag.

"I really do appreciate your coaching, Professor."

I'm gonna be bummed out when it turns out Dorothea's totally different than what I'm thinking. For now, I'm going to assume that she's a pretty studious individual with a decent heart but isn't so sheltered to be utterly ignorant. I also hope I was able to convey that their relationship is...mostly based on lust but still has mutual trust mixed in. not sure if I'll do a part 3 - guess it depends on if I find something else or if Boris or the like makes another rocking picture of her XD
