It was yet another boring class of Physics 101 at the St Louis Community College, and the students once again streamed into the small class room. There were around 15 of them, some having taken the class by choice, but most because it was a requisite for some other class. They all expected to see old Prof Swanson when they entered the room, but were surprised to see someone much cuter. The 23 year old pig-tail girl looked almost like a student herself, but she was in fact their replacement teacher for now, and somehow the students were apparently far more interested suddenly. As she taught class, most eyes stayed on her cleavage and bare abs, and the way Kathy walked was almost sensual. One student in particular seemed to have difficulties containing his/her desires, and Kathy could see how he/she was masturbating him/herself. So she made sure to give a better show..
For this RP I'm thinking Kathy could be the replacement teacher and you would play one of the students. She could either meet you after class, or humiliate you in front of the others after she made you soil yourself by acting the way she did.
