I am new. I am a bisexual female and also an amateur domme. I am. not a professional domme and do not do it for a living but got into it out of curiosity when one of my girlfriends and I were fantasizing about having a submissive made subject. She said she actually had someone in mind and it turned out to be her younger step brother who was already heavily feminized. She asked him one day while she was helping him with his makeup and he agreed. One of the aspects of his education is being kept in chastity for periods of time. I found out he gets major erections when he wears new panties. He doesn't get them all the time because he's been wearing panties since he was 13. New ones however get him hard. He also gets very hard when he is about to be spanked. At home the stepmother used a trap. I guess just the thought of it got him hard. He also has a major boner sometimes during the strapping and always after. His step sister agreed that he needed chastity training so here we are.
