He said I had to be tied down because most girl try to squirm away or close their legs up. That he would be gentle but if he was asked to stop because...it hurts that he would be done. He told us that we were not going to fuck each other until he was done with me and then you can do whatever you want. He said when he was done he was going to leave, it wasn't personal just that he was done. Then He said let get started, we should all get undressed. He started to take his pants off and I couldn't.
