Ex-school bully punished with math and orgasms

Lucia is a former bully who used to bully Lex when she was young, after some time she has gotten her revenge, she has her held in a room, handcuffed to the wall. She has made him dress in the school uniform they wore to high school when they were young. Lex enters the room where Lea is, arrives with a box full of ropes, unties Lucia’s handcuffs, and ties her hands with ropes, ties Lucia on the bamboo, with her body stretched to the floor and her hands forward, gags her with a bamboo gag, which allows her to speak enough for the exam. He binds each leg, joining ankles to thigh and finally anchoring each leg to the wall, tightening the ropes so that the legs cannot close and keeping them open.

Once he has her tied as he wants, he takes out the mega powerful hitachi, he starts the math test, Lucia was very bad in high school with math, Lex was excellent, Lucia was envious of her and made fun of her. Now Lucia is under Lex’s control.

Lex tells her the rules, he will ask her different questions, she has to get everything right if she wants to be free or else she will be punished and kept in detention. The longer she takes to answer each question, the more power he will give her with the hitachi in her pussy, it will progressively go up as the seconds pass without the correct answer until she gets it right or gives up.

Here we see a long scene where Lex gives her the exam, with different mathematical operations at different levels of difficulty, all the orgasms that Lucia has, are real with her consent.

Lucia fails the test, Lex punishes her by putting an armbinder blocking her wrists and arms, tying her to the bamboo. Lucia has failed, soon she will have another chance, another exam…
