Kinky girl fucks a dildo in the school gym

I was recently in the gym again to do a bit of sports and realize: No one else is there!This was finally the chance for me to live out a secret fantasy and really get it on the wall bars. Luckily I also had a cool toy in my sports bag, so I didn't have to do it with my fingers =)I just hope that the caretaker, who is sometimes out and about in the hall, didn't notice anything.
