My STEP-son and I are both submissive. I decided that he is ready to experience something different. I invited my very sexually dominant step sister over to play with us as she was MY first experience being sexually dominated many years ago. My STEP-son is inexperienced when it comes to being dominated as we always play submissively and gently and I have always been very protective of him. I held off as long as I could and while reluctant, it excites me to be dominated together with my STEP-son and I want to have this experience with him. I put a condom on him before his STEP-aunt arrived and put on the clothing that she told me to wear. I watch him masturbate and we both take directions from my stepsister as I use my vibrator and get very excited. I protest several times when I think his STEP-aunt is a little rough on him and he looks to me frequently for support, so I can calm him. After I cum, he cums in the condom. My step-sister immediately makes me cuff myself while she takes his condom off and squirts it inside her!! I protest profusely but cannot do anything as I am cuffed to the chair. I feel helpless but as I continue to protest and beg her not to take his semen I also try to remain calm and keep talking to my STEP-son lovingly, reminding him that I will always protect him and that his body belongs to me.
