I have only told 3 people this, but when I was 20, I fucked my marketing professor for the first time. We are now friends with benefits. I would guess she was in her mid to late 40s. A tiny German woman with graying black hair. Her face was like a 6/10, but her tits were massive and her ass was hypnotic.

I had noticed her staring at me every now and then, but I didn't think she was honestly checking me out.

Well, one day the only clean boxers I had were way too small and the only jeans I could wear had holes in the crotch because I had been lazy with laundry. I went to my classes, not really thinking much of it other than my balls were uncomfortable that day because of the boxers.

All of my classes had desks with coverings on the front except for her class which was in an older building. I sat down on the front row and started moving my legs around, trying to get rid of the pinched feeling in my testicles. About 20 minutes into the class, she suddenly just stopped talking and drawing on the dry erase board. Her cheeks became red and it took her about a minute or two to regain her composure. I wasnt sure, but it looked like she had been staring at my groin. I looked down and, to my horror, my balls had somehow slipped out underneath my boxers and were being pushed out of the two holes on my jean's groin area. I immediately got up, went to the bathroom, readjusted, and came back, making sure to sit with my legs close together.

At the end of class, she asked me to stay. I was so scared. I started apologizing and tried to explain that I didn't mean for that to happen. I was afraid I would be expelled. She interrupted my explanation and told me firmly we were going to her office. My heart pounding, I gathered my things and walked with her to the elevator. Inside the elevator, I apologized the entire way up, saying the truth, that it was an accident, but she didn't respond. The class got out at 5 so there wasn't many faculty members left, and her office door was covered with pictures, which I dont think they're supposed to be, but they were. We got to her office and my heart was throbbing. She shut the door, locked it, and I was shaking as I sat down and waited for her to call the dean.

She didn't.

She quickly pulled down her panty hose, sat on her desk in front of me, pulling up her skirt and spreading her legs, revealing plain white panties that were noticeably darker were I guessed her pussy was. I was shocked.

She told me to scoot the chair closer. I was in such shock, I didn't move. She slid off her desk, undid her skirt and let it fall, got back on the desk and started rubbing herself through her panties, telling me again to scoot up closer. I did this time, my cock beginning to twitch. I looked in her eyes and saw nothing but lust.

I tentatively reached a hand out and rubbed the wet spot on her panties, feeling her lips and clit. She nodded and told me to stick them in, her breathing becoming ragged. I did as I was told, using my other hand to pull her panties aside and stuck two fingers in. They went in easily and she was soaking wet. It wasn't the tightest pussy I had ever felt, but it was so hot that it was actually happening. My brain had caught up to my cock at this point and I was committed.

I slid out of my chair and got on my knees in front of her as she scooted to the edge of her desk. I then proceeded to eat out my marketing teacher, alternating between writing things with my tongue and rubbing her clit while fingering her g-spot. Professor was quiet for most of the time, only giving a soft gasp every now and then, but she bucked her hips against my face or hands the entire time. She came rather quickly, and squirted all over the desk.

She then pushed my face away, stood up, and slid her panties off while I unbuttoned and slid down my pants and boxers. I only got one leg out of them when she swiveled me around and had me sit on the desk. She then looked at me and told me to be quiet as I then received some of the most amazing head I have ever had. This little German woman knew how to gobble a cock. I laid on her desk while I gasped as I felt my cock head literally reach the end of her mouth, then take a downward angle as she swallowed me. Soft, wet gagging sounds filled my ears as she just gobbled my cock for the next 5 or so minutes. I've never met a girl that could do what she did to me. She let me throat fuck her until I told her I was about to cum.

She helped me off the desk and whispered in my ear only two words "fuck me," before she switched places with me and laid herself tits down on her desk. As I put my head to her pussy lips, she shook her head and said "no, my ass." I reluctantly pulled back and adjusted to the other hole. I had never been that into anal with girls, but I wasnt going to turn her down. Her ass looked amazing, and parting her cheeks and staring at her tiny hole, knowing I was about to be in there, turned me on in a carnal kind of way. To be honest though, I still was in shock at what was happening.

I pressed the head against her surprisingly tight ass. As I mentioned before, she was a tiny woman. The top of her head only came to the middle of my chest, so maybe that had something to do with it. Either way, as I started to push in, I went very slowly. She wasnt having it. She put her hands on the edges of the desk and immediately pulled so that she impaled herself on my cock. She let out a grunt as I was about 3 quarters of the way in her instantly. She wiggled as I pushed and we got me all the way in. I began fucking her ass slowly, then picking up the pace as she adjusted. I began fucking her hard, but she reached back and slowed me down by putting a hand on my abdomen. The slapping of our hips was too loud. So I was forced to slowly push in and out of her amazing hole. It felt like her ass was milking my cock to be completely honest. We fucked like that for a while, me desperately trying not to blow my load and just savor the pleasure as I began to realize I was balls deep in the ass of my marketing professor. This was an ass I had stared at all semester. I felt like I was in a porno.

I reached up and groped her tits. They were at least C's. Once I started feeling her tits, something in me broke loose and I pulled her off the desk. My dick popped out of her ass, but I laid down on the floor and pulled her down with me, immediately repositioning my cock at her asshole. She plopped right down, her ass greedily swallowing me back in while I reached up her shirt, sliding my hand underneath her bra and groping her tits. I began bucking my hips. Between the bouncing, she managed to unbutton her bottom three buttons and then reached up and undid her bra. She then tried to slow me down because the snacking was loud, but I just kept fucking her hard. Her pussy juices were running down her legs and onto me. Watching my cock slide in and out of her and feeling her soft tits in my hands made me want to just fuck her like an animal, so I kept fucking her hard.

She grunted "too...loud..." between snacks, but I just grunted back "just take my dick." Right at that moment she squirted again. I will never forget this. Where we were laying positioned her face to be reflected in a little glass frame on a small table in the corner. The way the sun was coming into the room, I couldn't see the picture, but I could see her face perfectly as she squirted again. Her eyes rolled into the back of her head and her mouth gaped open as her pussy started spewing juice all over my legs while her ass tightened it vice-like grip as I plunged my dick balls deep in and out of her precum coated ass. Right at that moment, I came so hard that my vision got black around the edges. I have only ever came that much a few times in my life. I shot load after load into her ass. So much cum that it began leaking around my still thrusting cock onto my stomach like a water pipe with too much pressure. Her ass came off my cock with an audible plop and I shot two more loads onto the back of her shirt.

She shakily turned around and bent down, managing to catch the last little spurts of my cum in her mouth. She sucked my dick clean until it was soft again, then licked my stomach clean of cum.

She then crawled up and collapsed on top of me, slowly rubbing one of her legs against mine while we caught our breath. I began French kissing her which she didn't really kiss me back too eagerly. After a few minutes she told me "get dressed and get out. Get dressed and dont you dare fucking tell anyone" her voice cracked on the last three words. I guess now that her horniness was gone, what we had just done had began to sink in.

Right as I was about to leave, she begged me not to tell anyone, much nicer than before I got dressed. I told her I wouldn't.

I ended up getting an A in the class, and gave the teacher my number. We fucked two more times that year once I finished her class. Im about to graduate, but we now fuck more frequently than sporadically. I'll usually text her when I'm looking for an easy booty call.
I have cum in that her so much, and she loves French kissing me now that she knows I won't tell, but I've never came as hard as that time when we were fucking on her office floor.
