Fucking My stepSon's Teacher to Keep Him From Failing Gone Wrong

Description: I meet with my stepson's teacher and he tells me that he is failing his class. i realize just how serious the matter is. my stepson has been having bad behavior in school lately. i try and see if there's something i can do to keep him from failing. i make a desperate attempt to save his grade by pulling out my tits and offering to be a big titted slut for the teacher. i suck his cock and then ride him. he makes a huge mess all over my tits and face. he then says he's not going to do anything about my stepson's grade. the teacher used me and i did all that for nothing. there's nothing more i can do. i now feel angry and humiliated.
