Ana woke up from her dream suddenly with a gasp. Her pussy dripping wet as she was on the verge of a powerful orgasm. Her hand immediately flew down to her clit and she rubbed hard. When she was finished she laid there for a few minutes, rubbing her wetness around her pussy. It felt so good she almost came again, but she remembered she had to get up and get ready for class and got out of bed with a sigh. She had been dreaming about one of her instructors at college. She had often thought about what it would be like to suck his cock. What his cum would taste like as it slid down her throat. She had a hard time paying attention in class because of these thoughts.

Her boyfriend HAD mentioned that he wanted to see her suck another man's cock. He wanted pictures and videos. She wasn't really into stuff like that but after he explained to her how much it turned him on, she considered it. Knowing that it would make him cum as hard as he said he would turned her on greatly and she had even gotten off a few times at the thought of it.

So one day, after these constant thoughts driving her crazy, she decided to go for it and stopped her instructor after class.

"Hey, I was wondering if you could show me that liquid penetrant testing again? It was super interesting." She said very sweetly.

"Sure! I've got time." he replied.

They walked over to the lab together and he unlocked the door and turned the light on.

He grabbed some safety glasses out of the cabinet and handed her a pair. His hand brushed hers as he handed them to her and she shivered a little at the thought of what she was about to attempt.

They walked down to the back of the lab and he opened the door to the storage area to grab the dye.

"Lemme just grab the stuff real quick!" he said.

But she couldn't wait any longer and followed him inside and closed the door behind her. He was facing away from her looking for the dye on the shelves. She turned on the video camera on her phone and pressed record and set the phone on a shelf. She walked up to him and wrapped her arms around his waist over his belt buckle and pulled.

"Whoa hold on!" he exclaimed, startled.

He turned around with a puzzled look on his face.

"You have no idea how long I've wanted to do this," she said seductively, "I know you want it to. I see the way you look at me during class. I can't ignore this any longer."

Before he had a chance to reply, she knelt down and unbuckled his belt. She looked up at him to see if he would protest more. When he didn't she gave him a big smile and giggled while continuing to undo his belt.

"I can't believe this is finally happening!" she thought to herself, "I'm going to make him cum so hard and when Robert sees, he is going to cum hard too!"

Her hands were shaking with excitement, she fumbled with the zipper on his pants.

"Here, lemme do it." her instructor whispered, his voice labored with anticipation.

He quickly unzipped his jeans and pulled his cock out.

"Oh my god!" she gasped. His cock was everything she imagined it would be. She marveled at the size and thickness.

It had a few nice veins running along the shaft. She could see him throbbing with excitement and that turned her on even more. She took it into her hands, looked at her phone sitting on the shelf and slowly licked the pre-cum off of the tip.

"Are you sure about this?" he said suddenly, "Anybody could just walk in here..."

"Even better!" she said and wrapped her lips around his cock and gently sucked. He sighed with pleasure and grabbed on to the shelf next to him. She took it out of her mouth and licked up the shaft a few times, swirling her tongue around the tip. She took his balls into her other hand and began to gently massage them. He groaned with delight.

She let out an excited giggle and took him into her mouth again, sucking a little harder this time.

"You're amazing." he moaned. She took his cock out of her mouth and smiled before lifting his cock and gently sucking on one of his balls. He gripped the shelf even harder and swayed a little.

"Mmmm you like that?" she asked. He nodded with his eyes closed, not even able to speak anymore. She noticed a chair in the corner.

"Take off your pants and go sit in that chair." she demanded. He eagerly obliged.

As he did this, she thought about where she would want him to cum. It would be amazing to feel his warm cum on her tits, but she also wanted to taste it.

The thought of tasting his cum overwhelmed the desire to feel it on her breasts and she knelt down in front of him and looked at the camera again and smiled. Then she took his cock in her hands and swirled her tongue around the tip again. He moaned a little louder. This made her extremely happy and she put his cock in her mouth again and began sucking even harder and playing with his balls. She loved the taste of his cock and she could even still taste the pre-cum and it increased her excitement.

"Robert is going to love this video." she thought, "I can't wait to see how hard HE cums while watching me suck my instructor's cock."

She took the entirety of his cock into her mouth and down her throat a few times and gagged a little. Her instructor grabbed her hair and she stopped and looked up at him.

"You like gagging on my cock, huh?" he asked her. She nodded and smiled glancing at the camera.

"Keep doing it then." he growled and he pushed her head down and shoved his cock down her throat over and over and she gagged again. He moaned loudly.

She looked up at him and he had his head back and eyes closed, clearly enjoying himself. She wrapped her lips around his hard, throbbing cock and began sucking harder and faster. She massaged his balls in one hand and began stroaking his cock with her other hand in time with her sucking. She could feel him getting close to cumming and she could feel that her pussy was soaking wet. She was close to cumming herself and she hadn't even touched her pussy.

She continued to suck and stroke and he began moaning louder and louder until she felt him explode in her mouth. She took her hand off his balls and began rubbing her clit furiously until she came while feeling his hot loads slide down her throat. When he was finished, she took her hand out of her pants and put her fingers in her mouth, tasting her delicious pussy while looking at the camera.

She couldn't believe that this had finally happened. Robert was going to be so happy with the video.

She looked up at her instructor and he was sitting limply in the chair still breathing heavily.

"Thank you." he said, "That was... incredible."

"No, thank YOU!" she replied and stood up. She grabbed her phone off of the shelf and stopped the recording.

"You have made someone very happy!" she smiled and turned around and opened the door, peeking her head out to see if anyone was in the lab. When she saw no one, she turned to her instructor and gave him one last smile and walked out of the lab. She couldn't wait to show Robert the video.
