Karin in Bondage 24

It's the soccer world championship in Brazil and everybody in Germany is very excited and don't want to miss a game when germany is playing.
But about the time difference to Brazil, some of the games start nearly midnight.
That is why Most teachers are starting their lessons later.
But not so our dutiful karin.

So some of the female students invite  her to a public viewing at one of the students house.
Karin hesitated a little bit, but then she thought that it would be a nice idea to spend an evening with her students.
But as soon as karin arrived, she was grabbed by two of the students and finds herself a few moments later tightly tied and gagged to a chair .
After the girls have finished tying up their surprised and confused teacher, they left her laughing with the words" so let's see if you can start your teaching on time tomorrow?
