Usually when you think about an "extra credit" situation in college, you think of some cute coed sucking her professors cock for a better grade. I know I do at least. I wouldn't have thought of it being me, a male grad student, tied up and taking my student's cocks however they wanted to use me! And yet here I am. This is what I get for being horny and posting an ad on craigslist. I had gotten back from the bar last weekend, drunk, horny, and feeling extra slutty. I'm normally straight and really don't have any attraction to other guys. When I'm drunk though, my submissive side comes out and all I want is to be used like a slut. I'm still not attracted to guys when I feel that way, but I just like the feeling of being treated like a cocksucking whore. I fired up my computer and posted an ad on craigslist saying I was a straight bottom slut looking to suck someones cock in their car. The idea of doing it in a semi-public way like that just made me even hornier! I couldn't drive, but I could meet them at the park at the end of my street. It didn't take long before some responses started coming in. I ignored a couple that were looking to cuddle and hang out, but finally found the right one. All he'd included was a picture of his cock and asked what time and where. His cock was huge! He had it held next to an old directtv remote control, and it was easily as thick and even a little longer. I could not wait to have my lips wrapped around it! I sent him the address of the park and he told me to be waiting there in 10 minutes which I eagerly agreed to. I changed quickly into some tight and thin black leggings with a pink stretchy thong underneath to make me feel extra slutty, and then headed over to the park. It was only a short walk and I felt like such a whore dressed as I was. I had worn these clothes before, and I figured from a distance they might pass for workout clothes, but up close they were clearly women's leggings. It didn't help that they were also thin enough that the outline and color of my thong was definitely visible from the back. I figured I would get there before him, but when I rounded the corner there was already a car waiting facing me. I only got a quick glance at what looked like a semi-new BMW, before the engine turned on and the lights blinded me. I was a little nervous at this point, but kept walking and heard the door locks click as I got near the passenger side. This was obviously the guy. I opened the door and quickly got in to see his cock already out and hard. Even though it was dark out, he also had on a hat and sunglasses, but I didn't think much of it since some guys don't want to be seen doing something like this. From what I could see though, he looked pretty young. Maybe early 20's. That was about all I had time to notice before he grabbed me by the back of the neck and pulled my head down to his huge cock. I eagerly opened my mouth to take it in and felt my lips stretch a little around his girth. I've only sucked a few cocks, but usually I could at least get them all the way into my mouth, and if they were thin enough could even deepthroat them. This one filled my mouth fast though! Even trying to swallow more of him down I could still see a few inches of cock in front of my eyes. Resigned that that's as far as I could take, I started bobbing up and down on his beautiful cock, swirling my tongue around the head and using my right hand to knead and massage his balls. I had been worshiping his cock for a few minutes when I felt him move around a little above me, and then felt the car shift into gear. I tried to pull off to ask him to stay close so I could walk back, but his hand held my head firmly in place. After a couple seconds I gave up and figured if worse came to worse, I would just ask him to drive me back after. I could hear him moaning a bit above me so I knew he would be done soon anyways. He started becoming more and more forceful too, pushing my head down harder and forcing his cock deeper into my throat. I would've loved to try and deepthroat him, but I just didn't have the right angle. Instead I kept my lips sealed tightly around his shaft and eventually felt him hold my head down tight as he started shooting into my mouth. After a couple spurts though he pulled my head off and shoved it down below his cock so he could shoot the rest of his load on my face. I wasn't thrilled with having cum on my face while I walked home, but didn't have much choice given how little leverage I had in my position. I felt like such a dirty slut, bent over in his car with his cum dripping onto my face, gasping like the eager slut I was. I could feel the vent blowing air on my ass so I knew my pants must've pulled down a little as I was working so my thong had to be showing. I was so horny I eagerly reached out to clean the last drops of cum from his cock and happily thanked him. Unfortunately I was in such a haze, I didn't even think twice as he pulled over and reached over me to push open the passenger door. I just pulled my pants up and climbed out, swinging the door shut as he pulled away. It took me a second to realize that he had dropped me off a considerable distance from the park. I recognized the neighborhood at least, but I was going to have to walk almost a mile back with cum on my face and dressed like a slut. I was a little annoyed for a second, but that was quickly overridden by how hot the situation was. I had just sucked a complete strangers cock and then been kicked out of his car further from home, without so much as a thank you! I felt like such a dirty cocksucker and it turned me on like crazy. The walk took a little longer than usual since I had to keep ducking behind trees or bushed whenever I saw a car. I also had to take a detour around a block when I saw a couple approaching on the same street. Eventually though I made it back to my block and practically sprinted down the street and up the stairs to my apartment. My computer was still on so I logged in quickly to shut it down properly, and noticed a new email from the guy I just blew. The first thing I noticed was the pictures. I pulled them up one by one in shock. The first was of me clearly lit up in the headlights. My face was very clear, as was my tight leggings and thong. In the bright light the leggings were almost transparent and the pink from the thong was more than obvious. Next up was me opening the door. I guess I was still a bit blinded by the light at the time, because I had no idea he had taken it. The rest were of me bobbing up and down on his cock. They looked a little grainy, like they were screenshots from a video, and it took me a second to realize that he must've wedged his phone behind the sun-visor when I wasn't looking. In some you couldn't see my face, but in others it was clearly me. And there was no mistaking the look of slutty ecstasy on my face as sprayed his load on me. Finally I read the text. It was pretty straight forward. Cocksucker Not bad tonight, but you could use a little more practice. Don't worry though, I'll make sure you get plenty. I'll be in touch soon, but I just wanted to give you a heads up. I know you don't have much influence on the grades, so instead you'll be the one earning some "extra credit" with me. You can either do what I say or I'll send these to Professor Hendricks. I have a feeling he wouldn't like knowing his TA is off blowing the students! You're now my bitch, and, gay or not, you're going to be spending a lot of time worshiping my cock! Sleep tight slut. See you in class! Your new Master PS. You look good in that sissy little thong. From now on, you will only wear thongs for underwear. I'll be checking and you had better not disappoint me. What had I done?! I was so horny I hadn't even thought about possibly running into someone who might know me. Let alone a student!!! Class was on Monday morning, but it was going to be a long weekend! Thank you for reading sirs, I hope you enjoyed it! I know I haven't gotten back to the intro yet, but it'll follow soon! I would love it if this were to happen to me, but if anyone has any other ideas they think would be hot, I might try and work them in too. I'm also on the lookout for an online dom so if anyone is interested you can email me at scslut4cock@gmail.com
