Fucking with my stepsons and her friend

My best friend's stepmother and I had sex a few days ago and my best friend was very upset... In order to keep him silent, his stepmother convinced him to have sex with her anyway, but not before calling me to fix things with me. best friend... She thought that the best idea for the friendship to return to what it was before was to fuck with both of them at the same time and show her stepson what a bitch his stepmother was!!
