It was pleasuring me deeply but I made up my mind and controlled my ejaculation. She leaned in front of me ready to be fucked in doggy style. I came b...ehind her grabbed her ass and put my cock in her pussy in one swift motion making her scream. Then I started pounding her pussy making her moan loudly. I continuously pounded her pussy making her cum in twenty minutes but did not stop and fucked her for over an hour making her cum 4 times more. Then I took out my cock and put it in her mouth to. Then one night during sex we were talking about my fantasy and I asked her again if she ever had a big cock. She was hesitant but I persisted I told her it wouldn't bother me if she told me. I knew she had experienced a big cock before because she wasn't telling me no. So while my cock was in her pussy I asked her "you fucked a big cock before haven't you"? I could tell by her moans and her bucking that she was reminiscing about someones big cock. I told her I was close to cumming and that I. .. go to work. She sobbed openly in front of her class and couldn't stop when she had to move to sit down... they were upset and... and... and she finally told them she had to sit still as her Grandpa had died - the only lie as a teacher she ever told. He made her admit it. And he then He told her next time, she had to teach normally - sit, walk, move, and he would WALK with her to school (not let her DRIVE) to school (almost a MILE) and already he had the principal's permission to. I heard a soft moan from Nikki as my tongue pushed in her widening lips and although I had no idea how she was going to get her legs back up I was more concerned about suffocating the poor girl.I felt her hands come up and wrap around me and as she tried to get a grip I found my shorts coming down again and as I manoeuvred myself into a better position all that was achieved was my shorts were halfway down my thighs and I could feel my cock pushing back into her mouth and OMG my balls were.
