Onderdanige stiefmoeder en stiefzoon gedomineerd door tante

Fanclub only. My stepson and I are both submissive. 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. My stepson 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 shy, it excites me to be dominated together. I put a condom on him before his aunty 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 aunty 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.
