Causing some pain to her attacker was a small victory for Vera though her mind was still in conflict on whether it was the right thing to do or not. Another tentacle wrapped around the Head Girl's neck, pulling her away from the tendril she bit. "Urk! St-Stop..." she gasped as more vile appendages came to wrap and bind her. The woman tugged at her bonds while the alien monster took control.

A hand firmly pushed the woman back onto the desk. Legs kicked but could not get any strength behind them. Breasts bounced as squirmed on top of the desk, chest heaving panicked breaths. Vera knew screaming for help was useless as nearly all the walls were soundproof. Not that any of the staff would be overly eager to help even a Head Girl against an alien guest. The woman's struggling at least helped her focus on the danger rather than the little voices in her head telling her to just let this all happen and submit to this disguised instructor.

Upper body laying over the desk, the desk's contents were sent clattering onto the floor as a spot was cleared for the lovely female. "You... You are doing something to my head. I know it!" Whether it was a blind accusation or not, it would not matter after the professor was done with this student. Soon, she would only remember what the alien being wanted her to remember. Vera's arms were soon pushed up above her head, causing her chest to thrust outwards more as she was once more bound and helpless before the disguised monster.

She pulled and squirmed, arms pulling hard, legs trying to kick, but it was an impossible challenge at best. With bodies muscled like snakes, the tentacles gave enough while pulling enough to feel like she was struggling while barely managing to move at all, great victories merely a matter of an inch. The tentacles pull her arms straight out over her head, while another two kept her feet on the ground. He smiles down at her beautiful face. His hand reaching out and grasping one of her bouncing breasts. He cups and squeezes it, watching her squirm and struggle, knowing she was helpless,

What am I doing to your head? He reaches out and cups under her chin with the other hand, fingers pushing into her cheeks, holding her head in place. Then as suddenly as he grabs her face, he releases her. His hand whips up to the crown of her head. Slowly, her rubs her perfect hair on top of her head. His fingers comb backwards through it a couple times.It's not so much as your head Vera, that I do something to, that comes at the end. Actually though it starts with what I do to your lovely hair.

The professor locks his eyes upon hers, except when she struggles, and smiles the entire time. His hand that was cupping and squeezing her lovely breasts, begins unbuttoning her top slowly. One button at a time starting at the top and working it's way down. His manicured finger strokes and teases along her bare skin as it moves lower and lower. Calmly and confidently he tells her, You should be concerning yourself with today's assignment though... He finishes that first thought as her undoes the last button of her top. Both hands, leaving her soft hair, and non-chalantly tossing her buttoned front to the side. With swift and strong movement her grabs both sides of her top and yank it open, as he smiles maliciously at her, as he exposes her top.

You have 3 mini-sales to make me. Should be quite simple for a woman with your experience, and such a gifted tongue. Should you fail, you shall be punished, as will be obvious. As he speaks, one hand slips down her front, moving slowly. As he reaches punished, it slips under her too short, barely a skirt, and begins rubbing her clitoris through her panties.

It's simple, he says, while he ceases and step back. He unbuckles his belt from his toned waist. Then slowly he begins to unbuttons his pants, and zip them open. Your first sale. You must sell me on not fucking your tight little pussy. You must convince me not to rape you right here and right now. You must sell me on not cumming and filling your little womb with my seed. His pants fall to his ankles, he bends and slips off his shoes, socks and pants.

You have 5 minutes. Fail to convince me, he says and moves between her legs. His hands slide up her smooth soft thighs. They reach up under her skirt and slide her black panties down before ripping them apart.... And I'm going to fuck that little pussy. He returns to rubbing her now exposed clit and lips.

And time starts now. He looks up at the clock on the wall marking the time, before returning to watching her beautiful Asian face as it all sinks in.

The professor grabbed the Head Girl by the face briefly before running his fingers through those long silver locks. "Nngh!" He felt her soft orb through her blouse before starting to unwrap his prey. A lacy black bra held the lovely orbs in check as her blouse flew open. Vera's eyes narrowed angrily as he tried to make a lesson out of this. His hand slid beneath her skirt, feeling the matching thong covering her netherlips.

"You know that is not a real deal," Vera hissed venomously, "That is not a sale, that is an ultimatum! Guess you don't actually know anything about business after all."

Feet continued to kick as her arms tugged at her bonds. Vera was stuck with this disgusting monster. Her anger towards this thing and his threats muted the voices in her skull. The professor did not seem to care regardless as her thong was pulled down her thighs. She was not sure why she was wearing such skimpy attire. But with how her head has been feeling, she had a convenient culprit on top of her. Fingers stroked her netherlips and goaded her hidden pearl out. Blood engorged the helpless nub, sending faint pulses of pleasure throughout Vera's lower body. Toes curled inside her shoes as she clenched her jaw and shuts her eyes tight, waiting for this monster to finish his business.

Vera's struggles continue against her bonds, writhing her sexy body enticingly before him. His finger tips slowly rub over her sensitive nub, rubbing a tiny circle over the sensitive skin. He manages to smirk even harder as she tries to slam his understanding of business.

All of life is but one deal after another deal. Finding that special someone, seeing if you are compatible and closing the deal and seeing if you work together. Making sacrifices and deals with yourself to get where you want to go or to get what you want. Giving up something now, whether time or energy to achieve later. In work you sell yourself and your value to a new boss.

Over and over, his smooth fingertips rub her clit, as he speaks, slowly deliberate circling, occasionally dragging fingertips horizontally and vertically across the nub.

You have been given your assignment. This is the first sale you must make. The stakes are high dear. Sell me on why I should not rape that wet little pussy here and now. When the pressure is on and the stakes are high, and you have the bad hand, nothing going your way, no time to prepare, you give up? You have 4 minutes remaining.

He looks as she closes her eyes, and flinches away turning her head, and one hand continues assaulting her pussy, while the other continues stroking her soft hair. He glanced to the clock his hard cock ready to take her, whether she failed to convince or didn't bother to try made no difference to the professor.

Hot blood pulsed within the swollen love button as the professor rubbed. Each drag sent shudders of pleasure jolting up and down the woman's spine. "F-Fine!" the Head Girl hissed, "If you... Nngh! If you r-rape me, I will report you to the Headmaster myself! You may be a guest b-but, getting you removed from teaching the class is very much pos-possible!"

She bit her lip and gritted her teeth before continuing, toes curling inside her shoes. "That means no more tricking the other students in the class. Fucking me is just short term when... Nngh... When you could have the other girls. Three classes with them still and keeping your substitute visage or give it all up here. I will even turn a blind eye to what you do with them as long as it is within Shokushu's rules. Three girls instead of me and their quality is not even a question on th-this resort."

There was not really much a student could offer a monster. Especially when monsters tend to break their own created rules and simply decide they were the winner no matter the result. But, Vera was not lying. She would very much report this to who she could and do all in her power to make his life as a fake substitute more difficult to continue. The lovely woman's position as Head Girl certainly gave her some influence if it was minor in many cases. Also, she could very easily aid the alien guest in getting the other girls well within his grasp. Knowing all their fates, Vera had little issue with doing all she could to save her own hide.

The handsome professor continues to rub her sensitive nub, fingertips velvety points of pressure, sliding over, across, and up and down as she agrees to partake in her assignment. She begins with threatening to report him directly to the headmaster, having his position as substitute teacher revoked. Unfortunately, the poor restrained Vera couldn't know she would never walk out of the room remembering what had happened to her.

He continues rubbing her sensitive genitalia as he listens to her unfortunate threat. Deciding to have more fun, he kneels between her trapped thighs, and move his angelic face between her thighs. His lips part and his tongue dances forward with quick, small strokes, teasing her excited pearl.

Next, her argument becomes more enticing. She offers up three in exchange for herself. How generous of her, little could she know he was already fucking all four of them weekly. He seals his lips over her clit, sucking and licking circles with his tongue around the sensitive flesh as she struggles to make the sale. As she finishes, he stands back up, breaking the slurping seal his mouth had made with a soft pop.

Are you ready for your grade Vera? He moves forward, one hand grasping his cock as he aligns the tip of his nine inches with her pussy.

Even if you walk out of here unraped, unharmed, and unmolested, do you think you will be able to report me? he begins pressing his hips forward, slowly pushing his mushroom tip inside her moist tight pussy.

Secondly, I already get to fuck your three classmates. He slides forward, burying his cock all the way inside her. He slowly begins to reverse course as he continues.

They are certainly amazing hot ladies, he continues as the tip barely remains inside her. He then begins sliding back up into her, but you Vera are in a class of your own. I love the way your body feels, a pussy made in heaven, an ass as tight as one could wish, and a mouth that is worthy of praise. Forceful thrusts begin as he begins raping her hard against the wooden desk. It was information, perhaps she would pay attention and use it, perhaps not.

A solid D performance... and he began giving her his solid dick over and over again.

There was no information to use as none was actually presented. It was not really surprising to Vera unfortunately. Of course he was a fraud, just like everything else on the island. If this was an actual business deal between professionals, simply saying 'no' was a waste of time for both parties. A side presents an offer then the other side either accepts, makes a counter offer, or ends the deal. If this was a real assignment then this monster would be looking to gain more than just one few good fucks especially from someone who has as many connections as a Head Girl.

With that, there was no real assignment to be graded on. This was just a monster wishing to fuck her like the others. The professor will just have to find out if she will remember to report him after he was done with her. With her willpower, it was not completely impossible. It seemed unlikely that it would come to anything if she did report the matter. Then again, this silver haired woman had shown to be rather resourceful in unexpected ways.

This alien guest had already fucked the other students of the class and was no doubt enjoying his time as a substitute professor. It was doubtful he cared what a Head Girl thought of his supposed proficiency in the given topic. Vera screamed as the guest's unyielding cock plowed into her hot welcoming depths. The lubrication made it less painful than last time not that Vera remember that encounter. She felt the tip slam against her insides, jolting her body with pleasure and discomfort. Her insides quaked and contracted around the hard meat. Toes curled as the alien creature drew back to thrust again and again. The office quickly filled with the sound of Vera's grunts and groans while the desk creaked and rocked back and forth.

The professor continues having his way with the sexy Asian. Her super short skirt lifted up around her waist as his cock pounded her sensitive pussy. As obstinant as she was, even Vera couldn't fight the noises pulled from her as she is raped against the wooden desk. Her arms occasionally pulled against the restraining tendrils, but she must have realized how useless it was. He took his time slamming his full length home over and over, as her exposed breasts bounced in time with his thrusts. His hands caress and squeeze her lovely breasts, thumbs rubbing at her nipples.

So damned sexy... Such a wonderful, hot, fuck... the alien compliments her in between grunts and groans of his own.

After a solid 15 minutes, he approaches his orgasm, and slams his hips home. His 9 inches buried to the hilt in her warm sex. Throbbing and twitching, he moans loudly, cumming...filling that tight pussy....

His slender body twitches as his hands squeeze her lovely flesh hard, almost to the point of pain. Finally, he seems to finish, as he slides his man-meat from her stretched depths.

He stands back, looking at the sexy woman he had just taken. Are you ready for your next sales pitch? Or do you wish to continue denying your fate?

"Nnnggghhh! Ahhhnnnn!"

The monster pumped his hot seed into the Head Girl. She twitched and shivered over the desk. Her insides tightened and loosened around the pulsing manmeat. Her pulse raced within the luscious mounds topped with throbbing teats. Toes curled and uncurled as the warmth of the alien cum seeped into her core. The professor drew away though the tendrils maintained their hold. The lovely Asian beauty was not going anywhere.

As mentioned in class, first impressions were important. How the disguised alien guest handled the first little game only showed how useless it all was. Vera was not going to give him the satisfaction of playing along any further. Not that it mattered if she did or did not as shown before. This monster was going to fuck her until he was satisfied and no one was going to save her.

"Shut up," she replied, "Just get it over with!"

The professor stands back awaiting her response, and true to form her response was one of denial, not willing to participate. He smiles, and walks the few steps to the closet, and opens the door, bending over to retrieve one of the slime filled buckets. Turning back around, he lifts the bucket over the restraining tentacles and walks back to the desk. With a soft thump, he places the bucket on top of the desk with another devious smile.

So you wish to skip your second sales question? So be it. You will get an F and your punishment.

The tentacles flip her over onto her stomach on the desk, bent at the waist. Her arms remained stretched out before her. He takes a hand and strokes it over her soft silver hair, the last time it would be clean for awhile.

He reaches for the bucket and pops the top off with a pop, as a sweet aroma fills the confined quarters of the classroom.

Since you refuse to participate, let us begin, and perhaps your sliming will convince you to make a better effort for your third part of the sales presentation.

His words would let her know what was coming. Would she know the mind controlling, sensation enhancing, and aphrodisiac qualities of the disgusting substance about to be poorer over her, or would she simply question why the goo was being dumped over her sexy lovely body and soft silky hair? His tentacles hold her tight, bent over the desk as he lifts the container and takes his time making the disgusting process proceed as slowly as possible. He starts at the crown of her head dribbling a small stream. He let's it begin to pile there, sticking to her hair, unable to dislodge the goo that would deliver the chemicals into her system even should she fight and shake her head. Once the goo amasses enough to slip down her forehead, down the sides to her ears, and down to the nape of her neck, he moves the pouring stream down her back. The slime flows in a thick stream over her hair as he moves the bucket slowly towards her waist and ass, coating her and her lengthy hair as he goes.

Still glad you refused an attempt to save yourself and avoid your fate Vera? the chemicals would begin infiltrating her system, her blood running hotter, aphrodisiacs driving her wild with desire, her nipples hardening and her pussy growing moist, muscles twitching.

He swirls the buckets around sliming not just the hair running down her back, but also the strands flowing around her on the desk. Her whole body slowly covering in the horrid sticky substance. Finally, he pours the remainder in a cool stream over the hair hiding her ass and down to her ankles, her skin coated in the revolting goo.

When finished, he sets the bucket away on the floor.

Now that you have been properly slimed Vera, would you like to participate in your third portion of the sales effort, or should we just skip to your next punishment for failure as well?
