My classmates and I go to private classes with our math teacher, we arrive on time, he asks us if we are preparing for today's homework? We tell him that we are ready, but the teacher is a pervert and likes to see us under the table, he throws the pen to see us under the table and see us through the mini skirt. He keeps looking at my friend's tits, she notices and gets upset and closes her shirt tightly so he doesn't keep seeing her. Then the teacher couldn't take it anymore and offered us a drink, but what we didn't know was that it was adulterated, and we drank it naively. and without us realizing it he took advantage of it to gag us and fuck us!
