We used to flirt A LOT in class. But I never thought it would become anything more than flirting. He was my lecturer for the age of 17 - 18 (just over a year) we would joke around and also had a lot in common when it came to our interests in music, art and gaming. When I was due to turn 18, he asked what my plans were and I told him some friends and I are going drinking at this bar in town. He just so happened to be at the very same bar that night (coincidence?) Anyway he came over to our table and offered to buy a round of drinks. After he bought a couple and the night went on I was quite a few drinks in at this point and he suggested we all go back to his apartment to continue the party. So a few of us took a cab to his place where we carried on drinking. I went to the kitchen and he followed and confided in me that he had been wanting to fuck my brains out but resisted the urge until now I was 18. I was obviously flattered as he was very hot and I was horny and drunk. I told him he could fuck me on one condition - he could only use the tip. It was a fun little dare and so we went to his bedroom and got naked. He folded me like a pretzel and stuck the tip of his big cock into my wet pussy. We stayed like that for a few minutes maintaining eye contact as I stroked the remaining shaft of his cock with my thumb and forefinger, a couple more minutes passed and he couldn't take it so he thrusted the whole cock in me and I let out a huge scream with pleasure. The teasing I had put him through was such a turn on that I was so ready to be plowed by him. He continued to fuck me raw for about 5 minutes until I told him I wasn't on birth control and this made him explode. He let out this gigantic moan as he climaxed and filled me with cum. I guess he had a bit of a breeding fetish so that line finished him off xD getting creampied by my college lecturer was such a fun way to end my 18th birthday
