Just like Tiffany a few weeks ago, Jenni misbehaved in class. She is punished even more than Tiffany: Jenni is in tight hinged handcuffs, ankle cuffs and even thumbcuffs! She has to spend a few hours of detention in this chair. But Jenni soon gets bored. She removes her shoes to see if she can slide off the ankle cuffs. Then she finds a key, but she is helpless, because of the tight thumbcuffs. School is hard these days...
