Two young girls play sex games with their partner

They were always punished, they were a pair of unruly girls who never obeyed and every afternoon was spent in detention. That afternoon was no exception but they were pleased to discover that they had a new detention partner. She was a new girl at school, I didn't understand why she was there, if I had always seen her all tender, obedient and docile. As they always spent the afternoon unsupervised, they decided to have a good time with the girl and use her for their perverse games. It didn't take them long to force her to undress and let them touch her, the girl was crying at the beginning but little by little she was loosening up and moaning with pleasure and wanting to never stop.
