Madoka worships the feet of Headmistress Kristina to not get kicked out of school

The story
Kristina is a private school principal. At the end of the day, she sits in her office. A knock is heard at the door of her office, and Madoka, an unlucky student and truant, enters the office.
Kristina was waiting for her to talk about her systematic absenteeism and, as a result, academic failure. But Madoka was silent and shy. The headmistress informs her student that she will most likely be expelled from school because of her situation. Madoka, realizing what’s happening, said that she is ready to do anything to stay in school.

Kristina liked Madoka’s offer and readiness, and she decided to take advantage of the plight of her student and help her, but on the condition that Madoka will have to work out and try hard.
Then, the headmistress walked up to the modest Madoka and strips her down to her panties. Madoka was very embarrassed but didn’t dare to contradict her. Moreover, she always secretly admired Kristina’s beauty.
The headmistress took out a pair of handcuffs and chained Madoka’s hands behind her back. As a result, Madoka was on her knees, her ankles were also handcuffed and her big toes were chained with small toe-cuffs.

Kristina made her lick her big bare feet properly. Madoka kneeled by the couch on which her headmistress lied and dutifully fulfilled her part of the contract – she worshipped the fragrant and slightly sweaty feet of her school principal. Kristina moaned and got very excited because Madoka did it great. Over time, Kristina takes out a Magic Wand and started helping herself to cum while Madoka sucked her toes. Kristina got a perfect orgasm and became very pleased, but she didn’t hurry to forgive Madoka so quickly…

For next, Madoka was hogtied tightly and ballgagged on the director’s desk, and Kristina tickled her bare petite feet. Having played enough with her student, the headmistress assured her that she won’t be expelled because she has paid off her debts completely. But instead of untying Madoka she simply left her alone. Topless hogtied Madoka had to learn her lesson.
