MY STUDENT ASKED ME FOR GOOD GRADES IN EXCHANGE FOR SEX, I AGREED BUT ON THE CONDITION THAT IT WAS ANAL AND SHE ACCEPTED, SO I TOOK HER TO A MOTEL AFTER CLASS. I COULD TELL THAT HER ASS HAD ALREADY BEEN STRIPPED BUT IT WAS STILL VERY TIGHT AND NICE. I PULLED HER PANTIES HALFWAY DOWN HER LEG, PULLED HER KNEES TOGETHER, PUSHED HER UP AND LET IT ALL THE WAY UP HER ASS.
