Use her mouth!

“Let's see you take the “oral exam.”” Mr. Allen said, chuckling. Su-jong's body instantly dropped to her knees. Her teacher pulled down his pants, showing that his erection was throbbing in his boxers. The foreign student pulled his underwear down, his dick popping up in her face. Rather than be disgusted, Su-jong lifted up her hand and wrapped it around the rod. Mr. Allen moaned as her silky hand began pumping up and down. Her other hand began softly massaging his balls. She could smell his sweaty scent, making her dizzy.

“Start using your tongue.” Mr. Allen ordered. Su-**** extended her tongue and leaned forward. Her muscle swirled around the head of his dick. Her teacher moaned even louder. He put his hands in her silky black hair, petting her in gratitude. Her tongue then began licking up and down the shaft, coating it in her spit. She could taste the sour sweat on his skin. Mr. Allen's fingers dug into her head and he growled.

“Go lower.” he said. Su-jong's tongue trailed down the dick to his sack. She began gently juggling one of them, before taking the testicle into her mouth sucking. Her teacher's hips quieverd a little. She released the ball from her mouth, and licked her way to the other one. She kissed it as if it were precious before sucking on it

“God, you were made for this!” Mr. Allen shouted. “Let's see how good at sucking you are!” Su-jong lifted her head back to his shaft. She wrapped her lips around the bulbous head and began sucking. She could feel his dick throb in her mouth gratefully. Then she began bobbing her head back and forth. Like an expert, she sucked and licked the shaft at the same time. Each time her mouth came away from his rod, more of her spit dripped down onto the ground. Mr. Allen's moans began echoing around louder and louder. He was loving this.

Abruptly, his fingers dug into her head. He bucked his hips and jerked her head forward. In a split-second, his dick was in her throat. The foreign student gagged and choked, feeling her air cut off. He pulled his shaft back out, making her cough and drool.

“That was great!” Mr. Allen said. “Can you do that again?”

“Yes.” Su-jong replied. She opened her mouth wide and gripped his hips. The teacher licked his and his eyes lit up in lust. He seized both sides of her head, gripping it tightly. He then jerked her face forward, burying her nose into his pubic hair. Her eyes rolled as his shaft rammed into her throat. Mr. Allen began pounding her face back and forth. Each time her face collided with his body, his wet balls slapped against her chin. He was using her mouth like a pussy, treating it like he owned it.

Rather than fight back, Su-jong's body played along. Her throat relaxed, and her tongue continued to coil around his pounding shaft. Every time his dick pierced her mouth, she pushed her head forward, helping him. Her saliva was flying and dripping everywhere. Her sucking mouth echoed around the room, sounding more like a porno than anything else. Mr. Allen threw his head back and moaned. His hips began to quiver as his shaft grew even larger in her mouth. With a creeping realization, Su-jong knew he was about to cum.

“Oh God! It's been so long! I'm gonna cum!” Mr. Allen cried. He slammed his hips against Su-jong's face as hard as he could, his dick in her throat. The shaft throbbed a few times as she gagged on it. Mr. Allen practically screamed as he stared down at the foreign student, his eyes burning with pleasure. Then he began pulling it back. Halfway out, Su-jong could feel the shaft pulse and then gush with his seed, sticky cum coating all over her tongue. After a few gushes, his dick popped free of her mouth. Ropes of his jizz shot all over her face, coating her cheeks, nose and hair with it. Mr. Allen groaned and bucked with every powerful throb of his dick. His climax seemed to go on forever, with the endless shots of cum completely soaking Su-jong's face. With a final, grateful moan, his shaft stopped gushing. He grinned a little and shoved his dick back into her mouth. As if she knew exactly what to do, Su-Jong began licking and sucking it again, drawing the remaining seed out. She swallowed his semen gratefully, even as he continued to moan and stroke her head.

“That was amazing!” Mr. Allen moaned. “Now then, what else should we do...?”

Su-jong's body jerked. It took a few moments for her to realize was happened. She could move her hands, then her legs. The time was up, and she was free! By instinct, she slammed her hands against Mr. Allen, hard. He yelped and tried to step backwards. His pants were around his ankles, so he tripped. The teacher went careening back into some desks, falling to the floor. Without wasting a moment, Su-jong jumped to her feet and went sprinting out of the room.

The exchange student knew she was covered in semen, and if anyone saw her they would think she was some kind of slut. The only thing she could think of was to run into the bathroom and clean herself off. When she entered the nearest one, she slammed the door and locked it. She ran over to the sink and began washing her face off as fast as she could. Her desperation, however, was interrupted.

She heard the dreaded popping noise. Su-jong shot up and whirled around, terrified. As she expected, the orb was in the room with her, grinning widely.

“You have fallen into a trap!” he cried.

“No! Don't!” she cried.

“Too late!” the orb turned towards the door. Su-jong followed his gaze, and saw with horror that the door was now gone. The door was gone, there was only a solid wall. She was trapped! The orb then floated over to the stalls, of which there were three.

“Let me explain the trap!” he announced. “Behind each of these stalls is a man you will have to please! Pleasure the man, the door comes back! Choose wisely, because while two of them have non-impregnating fetishes, one of them wants you knocked up! Take your chances and pick a door!”

“Wait...which one is which?” the student asked.

“If I told you that, it wouldn't be a trap! Take your pick and take your chance!” The orb then popped back out of existence. Su-jong licked her lips, which still tasted like Mr. Allen's jizz. She had just gotten out of a horrible situation, and the orb and dropped her in another. Her eyes darted from one stall to another. She tried to look under them, but there was nothing there. Likely the man would appear when she opened the door. The student took a deep breath and let it out weakly. She had a one and three chance of ending up pregnant...but she had ****. Which stall to pick?
