My best friend Paulina and I had a lot in common except for one thing, chemistry. We were in the same class for that subject and while she was excellent in it, I was terrible, struggling with homework and lab. Paulina was nice enough to help me whenever possible.
Our midterm was coming and she tutored me as best as possible, but I was still struggling, then an idea came to me, why doesn't she help me during the test? She was appalled I could think of cheating, but I was out of ideas and if I failed this test, I will likely fail the class, preventing me from graduating on time. Paulina refused, knowing the ramification if we got caught, but I begged her nonstop to do it if she was really my friend. She soon agreed, but said she would not this again, which I was okay with. Our exam was multiple-choice and we sat at the room's rear corner with me behind her, so it would be hard for our teacher, Mrs. Hunter, to notice her giving me hand signals to say which letter was the correct choice.
That day we finished first together after Paulina gave me all the answers, but as I did not want to make Mrs. Hunter suspicious, I pretended to struggle until everyone else finished their tests. I was relieved, believing we got away, but a week later, when Mrs. Harris returned the tests, she did not grade mine nor Paulina's and asked us to see her after class. I knew at that point we were busted.
After everyone else left, we sat by her desk together as she asked about Paulina's odd hand signals during the test forcing us to admit to our cheating. Mrs. Hunter was stunned and threatened to fail us both. Not wanting Paulina to suffer for my idea, I begged her to just fail me, but Paulina felt she deserved to be punished too as she agreed to help me cheat.
We argued for a bit before Mrs Hunter said she would forget this happened and pass us both under two conditions, we not try this again, which we agreed to, and have threesome sex with her at her beachfront home that weekend, surprising us. We found it gross to have sex with our teacher even if she was young and attractive, being just 28 and it would be legal as Paulina and I were both 18, but after she threatened to expel us from the class if we did not do what she said, we agreed to it.
That Saturday, she drove us to the house and seeing how nervous we were, had us relax at the beach first. Paulina and I stripped to our bikinis. Mrs. Hunter, who wanted us to call her by her first name, Ellen, stayed clothed. We lay facedown in towels on the sand as she gave us lotion and massages to calm us. She also untied our tops or bottoms, which felt great.
