Use her pussy!

“I haven't been with my wife in so long,” Mr. Allen said. “I just want to be with a woman, as a man is supposed to be. I know it's wrong, but can we have sex?”

“Yes.” Su-jong replied. The exchange student tried with all of her might, but the only strain was in her brain. Her body worked by itself. She reached down to her pants and let them drop to her ankles. Mr. Allen's eyes drank in her nearly naked body. Her shirt and bra were at her neck and her pants at her feet. Only her plain white panties were left. Mr. Allen pressed his mouth against hers. He pushed her against a nearby desk, putting her ass on it. His hand trailed down her stomach and slipped into her panties, one of his fingers pushing inside of her, swirling around. Rather than be disgusted, Su-jong shivered felt her pussy begin to tingle. She moaned against her teacher's mouth as his tongue explored inside.

As if by instinct, her hands went forward and undid his pants. His erection popped free from his boxers. She wrapped her supple hand around the rod, pumping it. His dick throbbed and he groaned. Mr. Allen stuck a second finger inside of her and began pumping them in and out. Su-****'s pussy throbbed around his moving digits. Mr. Allen could feel her hot fluids drip onto his skin and soak into her panties. The teacher pulled away, a string of his saliva between them. Her grinned, his face full of lust.

“You shouldn't soil your panties naughty girl!” he teased. “Let's lose them!” Su-jong's hands seized the hem of her panties and slid them down her creamy legs. Mr. Allen stared at her wet, engorged folds for a few moments. Then he grabbed her and flipped her around. Her feet game to the floor and her stomach was pressed against the desk. Mr. Allen's hands traveled up and down her back, as if admiring it.

“My wife would never let me fuck her from behind.” he growled. “You'll let me, won't you?”

“Yes.” Su-jong said. She felt him spread her legs apart. She screamed as loud as she could in her brain, but her body simply went along with it. Mr. Allen pressed the head of his dick against her entrance. He rubbed it back and forth, coating it in her glistening fluids. Then he began pushing inside. With every inch, he moaned louder and louder. Su-jong could feel her canal spread apart, as if welcoming him. After what seemed like an eternity, their hips met. Mr. Allen gasped several time, his legs bucking as if tying to find a deeper spot.

“Oh God!” he cried. “You feel amazing!” He laid his body across her back. He put his hands on top of hers, lacing their fingers together as if they were lovers. He began pumping his hips, slowly and deliberately. Su-jong was shocked to find that her body loved it. Streaks of tingling pleasure went up her body. She moaned, overwhelmed by the sensations. Mr. Allen kissed and nuzzled her neck as his dick came away from her insides a little wetter each time. He began increasing his pace, his balls slapping against her hips. The wet noise of their lovemaking began echoing around the room. If someone entered the room they would find Su-jong moaning, her pants around her ankles, and her teacher's dick inside of her.

Mr. Allen thrust himself deeply, his dick hitting her cervix. Su-jong shrieked, a dull throbbing clenching inside of her. She had been incredibly close. Mr. Allen paused for a moment, his hips quivering. Su-jong was terrified that he was cumming, but he wasn't. Instead her put his mouth next to her ear, panting like an animal.

“This is incredible!” he growled. “Is it great for you too?”

“Yes.” Su-jong moaned.

Mr. Allen kissed her cheek. “It doesn't have to the only time. I probably shouldn't decide this on my own...but how about you carry my child?” Su-jong felt a bolt of fear shoot through her. “My wife can't have a baby, but you're young and fertile. Will you do it?”

Su-jong wanted to scream 'NO!' “Yes, I will.”

Mr. Allen smiled. He began pounding his hips against hers with all of his might. Su-jong felt the waves of pleasure begin again. Over and over they swelled, threatening to overpower her. She moaned louder and louder with every wave, her hips quivering against Mr. Allen's thrusts. When her body could take it no longer, it unleashed a torrent of her juices. The exchange student shrieked at the top of her lungs, a flood of tingling pleasure washing over her body. Her hot fluids squirted against Mr. Allen's dick with every peak of her pleasure. Her pussy clamped down on his shaft, causing his own hips to quiver and to grit his teeth. Mr. Allen didn't let up for a moment, pounding through it and allowing her ride her climax much longer. As her orgasm faded, she could feel Mr. Allen thrusting against her desperately. She could feel his body shaking on top of her as he moaned in her ear. He was about to cum, she could feel it!

Suddenly, Su-jong felt strength return to her body. She moved her leg, then flexed her fingers...and they obeyed! Time was up! She gasped and turned her head towards Mr. Allen.

“NO! Don't...!” Instead of listening, his lips pressed against hers and he held her face. She tried to push him away, but only succeeded in grinding against his dick. He moaned against her mouth, his shalft swelled, and warmth exploded inside of her.

Su-jong abruptly had another climax. Her pussy clamped harder than before and even more of her juices gushed out. A bolt of pleasure shot up her spine and into her brain. Every muscle in her body clenched and spasmed, not in pain, but bliss. Her pupils expanded, as if she was a **** addict getting a fix. What felt like electricity danced around her brain, frying every nerve it found. Mr. Allen was lost in his own delight. The first gush of his seed flooded against her cervix. Every subsequent one felt just as strong. He moaned against her mouth as he experienced the best orgasm he ever had. His seed managed to fill her entire canal and even dripped out. Still his dick continued to twitch, trying to pump even more into her. After a few fruitless thrusts and some dry throbs, it finally ended. He slumped against his student, panting in her ear again. He raised his body back up. With a grin, he pulled his dick out of her painfully slow. The more of his girth that came out, the more of his seed that dribbled down onto the floor. Finally, the head popped free and a gush of sperm followed.

“That was the best orgasm I ever had!” Mr. Allen announced. “So Su-jong, excited to carry my baby?”

Su-jong stood up and turned to him, grinning. “SO excited!” She wrapped her arms around Mr. Allen's neck. They kissed again, deep and long. Their tongues batted against each other as they giggled and moaned like lovers. They pulled apart, still smiling.

“Think you'll get pregnant from this?” her teacher asked.

“I know I did!” Su-jong replied eagerly. “I'm very fertile right now!”

Mr. Allen cocked his eyebrow. “Doesn't mean we can't try again and make sure.”

Su-**** giggled at him. “Of course not, you're a great lover! What should we tell your wife though?”

Mr. Allen considered it for a moment. He could tell her about Su-jong and make it like she was their surrogate, or they could run away together and start their own family. Decisions, decisions...
