I slept with my (kinda) professor as a thank you for doing me a favor [FM]

I’ve always been naturally good at school. So I’ve never had to sleep with a teacher to get a good grade. I have, however, slept with a professor, I just didn’t do it for the grade. My sophomore year of college, I had to take 2 science classes and a lab. So, I chose to take the geology lab. The geology professor was an old timer who required his own textbook for the class. That seems like a “legitimate” way to make sure people have to buy your book. He thought of himself as the “regional expert” on all things geology. But his time was precious, so he delegated anything outside of lectures to the grad students in his department

One of his grad students, Lance, was a professor for the lab I was in. The lab was once a week, every Wednesday night. And this grad student turned professor took a page out of the department lead’s book and thought his time was extremely valuable as well. And if you missed even 1 class or field trip, you failed the entire class. This wasn’t an issue until near the end of the semester.

Class was simple enough as long as you listened to the lecture and the lab was basically a regurgitation of the workbook we had to fill out. Every week I would always finish mine with no problem then stay late to help the students that shared my lab table. And every week on my way out, the grad student would offer “ If you ever need any help, I am available outside of class”. Even though he had to know, I really didn’t need the help.

Then I ran into a scheduling issue. I had already signed on to go on a group trip for a different class project at the same time that he scheduled one of our class projects. The original date had been postponed because of weather, so the time he picked just didn’t work. So after class that week I waited until everybody had left to go up to and talk to him about going at a different time. with a different class, or missing the trip all together.

So, I told him the issue and he told me that all the other classes had already been on the trip. But he would make the time and meett me there at the field trip location himself so I didn’t miss the field trip. And, he would make it available to anyone else who needed the rescheduling too.

The day of the arranged time, I drove to the site and parked in the mostly empty parking lot. Since it was still early spring not many other people were there that day. I got out of my car and headed into the park. I stood by the pre-designated spot. After a few minutes of waiting, Lance walked up alone. He handed me the workbook and indicated that we should move further into the park.

Confused, I asked, “Isn’t anyone else coming?”

“ No,” he told me, “you’re the only one who needed an alternate day to do the field trip.”

I nodded in acknowledgment and took the workbook. “Thank you,” I told him and we continued moving further into the state park.

I worked on my worksheet as we moved to several different locations around the park. He helped me fill out a few things and it was about 20 minutes before we stopped to take a little break. I told him, “I am really grateful for you taking this time out of your schedule to do this for me. It really means a lot.”

“Well you’re gonna fail the class if you don’t have this field trip as a part of your lab so you should be grateful,” he told me.

“That’s intense, but I’m really grateful”. I said with a wink.

“Oh, really how grateful?” He came back playfully.

We continued our trek around the park exchanging flirty banter. After I filled out the entire work packet, I was confident I had gotten everything right. I handed it back to him. He took the packet back from me and replied “great, thank you”. But then didn’t move to leave

“I really am very grateful. I’d like to show you how grateful”.

“Oh yeah, how’s that?”

“I’ll show you in your car,” I shrugged, moving to walk out of the park.

He caught my arm, I looked back at him but he just shook his head and took the lead, pulling me towards his car.

We got into his car, with me in the passenger seat and him behind the wheel. He didn’t seem to know what to do at first, so I leaned over and kissed his neck, running my hand down the front of his pants. I could feel the bulge there, clearly just the idea of what I had been suggesting earlier had gotten him excited and now that we were here, he was fully erect.

I undid the fly on his pants, took the length of his shaft in my hand and worked it up and down. His eyes changed as he looked at me, shifting from uncertainty to longing. He slid his hand down my back and onto my ass, pulling me forward.

I moved with his hand nudging me forward and took him into my mouth. My head moved up and down, slowly at first and then picking up speed. My breasts were pressed against the middle console as I lifted and fell. He groaned and tangled his fingers in my hair, helping me keep a rhythm.

After a few minutes, his dick got harder under my touch and it swelled inside of my mouth. At the same time he let out his loudest groan yet, I felt him cum in my mouth. I slowly worked it several more times as he finished his orgasm.

I sat up after a moment, adjusted myself, and told him, “See you in class!” before climbing out of his car and moving back toward my own.

A few days later, I took extra time to get ready for class. I had some ideas of how to show my “gratitude” for his time. For going on an extra outing with me, I wore a dress with knee high boots and no stockings. In the lab that day, I dragged my feet on doing the work book, instead of flying through it. It took so long that I was the last one working in the lab when I heard him close the door after the last person left.

It was late, the lab started at 7 PM and could go as late as 9 some nights. We were always the last people in the building when we got out, so the rest of the building was silent.

I finished my last problem on my work book and stood up slowly, pulling the workbook up with me. I moved to the space right in front of him and, instead of adding my work to the pile, I handed it to him. He glanced at it and set it on the pile, moving from behind the elevated lab table.

“It looks good,” he told me, “I don’t think you need any help with this week’s assignments.

I shook my head. “I thought we could continue what we started the other day.”

He held himself back for a long few seconds, not saying anything. I thought maybe I had over stepped this situation and read him wrong. But then he pulled me towards him, and his mouth was on mine. His hands ran down my sides and were on my hips as he pulled me closer to him. He reached down and hiked up one side of the just over knee length dress I was wearing, the fabric bunching in his hand.

I threw my head back, as he moved his lips down my jaw onto my neck and then to the exposed collar bone on my chest. I let out a soft moan and he pulled away suddenly.

Then, he put his hands on my hips and set me on top of the tall table. Luckily, all the papers were on the other side so he didn’t send them flying everywhere. His hand reached up my skirt and his finger hooked around the fabric of my panties at the waist. He yanked them off.

He quickly undid his fly and I bit my lip as I watched him in anticipation. I had never had sex on a lab table before.

Before he penetrated me with his dick, he used his fingers in a quick motion to make sure I was ready for him. I was.

He moved his fingers inside me as I squirmed and moaned on top of the table. Then he quickly pulled them out and almost as fast, they were replaced with his dick.

I wrapped my legs around his waist as he thrust into me. He held my bare hips as leverage, and yanked my dress totally up to rest around my waist like a very ineffective belt.

I urged his thrusts on by squeezing my legs tighter around him and he complied. Then, he moved my legs so my knees up against my chest but spread wide open .

This gave him such good leverage into me as he pumped out a rhythm, faster and faster. I dug my nails into my knees, trying not to lose the weak grip I had on them. He kept me balanced and was able to use my hips to meet his thrusts. My ass was barely on the ledge of the table, only his iron grip kept me from falling forward.

We tried to keep our heavy breathing and moans muffled, just in case there was someone in the building, but he couldn’t stop himself from letting out a loud groan as he came.

My legs were shaking with the after effects of the pleasure. I slowly lowered them to the floor and he helped me off the table and to stay upright on my feet.

“Same time next week?” I asked him.

“Fuck yeah.”

We screwed every week until the end of the semester. The only exception being a week when he had a guest professor. Our class finished except for one last field trip to the lava tubes. That would be the final grade of the class.

Our class rode together in a big charter bus the school either had or rented for us. I sat in the front of the bus alone as we rode to the site of the field trip. When we got there, he handed out workbooks again, the whole staple of the class, and gave us basic instructions. We were allowed to roam around and fill out the books on our own or in groups. We were also allowed to go into the caves as long as we were careful and met back at the bus in a little over an hour.

The entrance to the tube is sketchy. There are boulders and rocks to climb over and under to get into the space that leads into the remains of an ancient volcano’s lava vents. The cave is pitch black inside and after a few feet, you can not see even a few inches ahead without the aid of a light.

It’s also really cold there. The temperature holds around 45°F all year round. I brought a hoodie with me, and two flashlights because we were told ahead of time about the conditions inside the tubes.

I noticed that many of my classmates were not interested in going very deep into the tunnels, so I decided to explore alone. Then I heard footsteps hurrying to catch up to me. It was Lance, apparently I had a buddy to go exploring.

We were pretty deep inside the system when I said, “it’s a bummer class is over.”

“Yeah, it was a lot of fun… Do you think we could get away with one more time?” He wondered out loud.

“Here?”

“Why not?” he said with a shrug that I could only see because I had turned to look at him with my flashlight.

“Alright.”

It was very dark and there was no one around. It was also really cold in there. We found a little nook away from the main parts. We had to crawl a little at some points. When we found a spot that looked good, he looked at his phone, checking the time.

“Shit!” he exclaimed, “We’ve got to be back in less than 25 minutes. It took forever to get in here!”

I laughed and pulled him against me. He seemed to relax almost immediately and his hands slid under my hoodie and shirt to run up my back.

I heard him unbuckle his pants, we had turned our flashlights off and it was pitch black, I guess he was worried about time. He spun me around and nudged my pants down to my knees. I leaned forward, my hands were against the wall to hold my balance. I felt his hands run over my ass and over my wet entrance, he couldn’t see anything and he was familiarizing himself with where things were before… he slammed into me suddenly and I let out a low moan.

He started moving so fast, right away, racing towards a finish line where we both won. His left hand was gripping my hips and his right was wrapped around my front, playing with my clit as the pleasure built inside of me.

I was worried about sound carrying so I covered my mouth with the sleeve of my hoodie and bit into it, muffling the sound of my breathing and my moans. He also was trying to keep himself quiet but I could hear the muffled sound of his hard breathing as he continued to slam into me.

I felt him swell inside of me as he came and he was unable to hold back a strangled sounding moan as he fell forward a little, leaning on top of me for a moment. I took one breath, two breaths, before pulling away and straightening so I was standing fully.

We both fixed up our clothes and made our way back to the bus. I was disappointed that the class was over, but I did pass and it was a lot of fun.
