I got tempted and pushed my middle finger into her ass and thumb into her pussy, simultaneously, finger fucking both the holes as well as tonguing her...clit. This was driving her wild and she came crashing and went still for some time. I also got exhausted with so much of licking and sucking and my tongue started aching also. I just put my head in her lap and closed my eyes and started enjoying the musky smell of her pussy. Now she lifted her boobs and offered them to me. I fell on her and. At the end of each session we would be given a grade with apunishment based on the grade: A- 5 swats with a riding crop. B- 15 swats with a paddle. C- 25 with a paddle. D- 30 with a light whip. F- 50 with a paddle, 10 with a riding crop and 5 with a riding crop to the balls while wearing a bigger butt plug, and nipple clamps.The F also had "her" mouth washed out with soap.After each session the highest grade was allowed tomasturbate, or as she called it "squirt". She said studsCUM, men. Sue was moaning and telling me to fuck her harder. I wrapped my fist around her hair, pulling her head back. She yelled, “Don’t stop! I’m cumming!” Her talking dirty to me was all it took to send me over the edge. I came so hard that I thought I was going to pass out. I pulled my dick out smearing our cum across her but , and laid on my side facing her, trying to catch my breath. My dick laid limp on my thigh, glistening with a mixture of our sex.Sue told me to lay on my back. I thought to. I was startled. My bag fell off my arm, as I was struggling to let go. He came near me, and said, ‘The next time you dare to be late, just know that it’s going to be way worse than this.”I was gasping for air and finally, he let me go. I touched my neck and coughed a little. Just when I had let out a sigh of relief, he pressed his lips on mine and started kissing me.Tushar was full of lust, and there was an urgency in him. I kissed him back too. He tasted sweet. His tongue twirled around mine..
