Student Ass JOI 4K

(THIS IS THE 4K VERSION!) Your student hasn't been on her best behavior lately. She doesn't work hard and her grades are failing because of it. After class, you try to have a conversation with her about it. She seems really adamant about NOT staying after school for extra credit, but instead offers a proposal... What if you gave her just a passing grade for jerking off to her ass? It seems like an offer to good to be true, but when your student starts making accusations of you staring at students butts all day, you feel you have no option but to say yes! Your student teases you relentlessly with her full ass while giggling at you. When she counts you down to cum, you accidentally unload early, all over her perfect ass!!!
