I found a link on this website a few weeks ago (don't know how old the post was). I think the person who posted it was Slave_Kris but I can't be sure. It was a butt plug. If I remember right, it was red and gold. It had a cylinder thing that you could press and expose a hole for a lock to go through. When you pressed that cylinder thing-y in also opened into four parts to prevent it from coming out. Does anyone remember seeing this and if so can you give the link again?
