This is the 4th session and you are late for class. I am annoyed because you are wasting my time for not being on time. I am irritated by you. I welcome you to the class of Building up your stamina. Wasting no time I tell you to unzip your pants and start stroking your cock. I am also annoyed that I always have to do all the work. I have to fuck the cock inside of me and I have had it. This time the cock inside of me will pound me hard. Then starting to instruct the guy to fuck me hard. He's doing a good job but slows down after a while. I get really mad at this. After a few attempts from him I just lose it and tell him I will do the fucking and start to ride him with my head tilted backwards. I will make myself cum. Your punishment for being late are that I am not letting you cum because it seems you have not practised in the time we didn't have class. Also telling the guy that he is bad at what he's doing. Eventually after a while of pounding and fucking I ask him if he think he will be able to cum in my pussy, giving me a nice creampie. He says YES. He fucks me hard and fast until he cums inside of me. For his punishment for not doing his job good I take out his cock to show you his cum dripping out of my pussy and tell you that he was only allowed to cum because he can fuck me. I put his cock back inside and ride him more as a post cum punishment. Then again take out his cock and stroking it. Letting him moan about the sensitivity of his cock. I hope this learns you a lesson to not be late for class again and not to slack.
