Chemistry lessons

I failed my chemistry class and my chemistry professor detained me and asked me to attend extra classes after school. I accepted his offer as his looks were worth it. The bell rang and all the students left. "Time for your extra classes" said the professor while waving a book in his hand. He locked the door which made me a little suspicious but I ignored that. after that he asked me to come towards him. I walked closer to where he was standing. "do you remember our last lesson?" he asked. I nodded and said "yes the human chemistry" . "yes we will be continuing that today, now remove your shirt quickly".

yes he have been teaching me about sex all this time and I went along with it because it was fun.

I removed my shirt and my boobs dangled as I wasn't wearing any bra today.he placed his hand on my neck as he said "why don't you pleasure me today" I nodded and bend over between his legs. I unzipped his pants as his dick popped out and hit my face. I started licking from the tip slowly taking all of his length inside my warm mouth and gave him some aggressive sucks as he groaned and grabbed my hair and thrusted his dick deeper inside my throat. after cumming inside my mouth pussy once he asked me to stand up. he caressed my boobs and sucked one of my nipple. I moaned and arched my waist in pleasure. after seeing my reaction he sucked it more passionately.

he then asked me to remove my pants and I did as I was ordered. he removed his own pants and rubbed his dick against my pussy "look at your pussy being all wet, just like a whore" I moaned more at his harsh words as I liked his rough tone. he playfully teased my clit until I was soaking wet. he then nudged the entrance of my hole with the tip of his dick and rubbed it there for a few times while groaning. when I was wet enough he used his fingers to spread my precum into my Hole's entrance so he can enter without any problem. after that he slowly pushed his dick inside me while groaning. I moaned at the pleasure I was receiving and begged for more "sir please move faster" I said while moaning " as you wish" he said while increasing his pace. slowly his thrusts started getting more and more wild. I came all over his dick due to all the pleasure I was receiving "I am cumming too" he said as he removed his dick from my pussy and came all over my belly. "this will be all for today's lesson" he said while dressing himself before leaving.
