Oh Professor, I'm your best student won't you let me miss a little bit of class so I can pee? I beg and beg and you finally say you'll let me go if I show you what I have on under my cute schoolgirl outfit (Calvin Klein sports bra and tiny pink thong.) I end up peeing in my panties a little bit because I just can't wait any longer and you tell me I can finish by peeing into a glass in front of you but first I have to strip out of my clothes. I end up playing with my piss for you - pouring it in my mouth and all over my sports bra before taking it off. I pour piss into my mouth and all over myself a few times and finish by using my fingers to cum for you. We finish up right in time for me to get dressed for gym... No wonder you're my favorite teacher! :)
